Discussed traditional Die Casting and the applied current situation that squeeze Die Casting to make craft and equipment, introduced the craft character of craft of extruding Die Casting and its economy, put forward to use the method of craft of extruding Die Casting on equipment of common Die Casting. Keyword: Crowded Die Casting builds die forging of machine of Die Casting of extruding of craft of extruding Die Casting one, crowded Die Casting builds craft and equipment application current situation to squeeze Die Casting to built a technology to invent 65 years, what it has powerful technical advantage, already took seriously for place of mechanical workmanship industry. Suffer what traditional thinking means and equipment develop lag to restrict regrettablly, the dominant position that crowded Die Casting creates still not be able to the most sufficient show. Uptodate crowded Die Casting builds craft to squash in order to open type mould vertical basically means undertakes, with the horizontal with highest work efficiency craft of cold room Die Casting fails to come true compatible. Develop the vertical that rise to shut a model to fill in recent years model crowded Die Casting is built, the " essence with the invention 40 years ago, fast, principle of close "Die Casting is same, it is shoot an orgnaization in order to press to undertake filling shrinking, its nominal pressure is finite, did not achieve what crowded Die Casting builds to fill shrink to ask than pressing, strictly speaking, still cannot count the crowded Die Casting on real significance is built. Compare with photograph of Die Casting technology, existing crowded Die Casting builds equipment work efficiency not tall, precision of dimension of spare parts figuration is low, cost is relative taller. Because the automation rate of equipment is low, taller to skill requirement of the worker, operation difficulty is greater, labor intensity is high. Same part, 2 what squeeze Die Casting to build the workshop cost of craft to be Die Casting craft about- - 3 times. Add pressure shoot a system to be not perfected, the part with complex structure is produced hard come out, restricted crowded Die Casting to make the wide application of craft. Crowded Die Casting builds craft to extend the issue that uses a presence, because the lag of equipment development arises,be. The crowded Die Casting of uptodate tradition makes craft and equipment, the biggest crucial reason depends on failing true with device of traditional Die Casting pressure shoot a system to be united in wedlock effectively, add up to model, lock model and extruding how to combine the issue that rising is its key well. Do not break through this, the technology potential that crowded Die Casting creates cannot be developed completely, its are right of craft of traditional Die Casting replace sexual advantage to also be conveyed adequately hard, technology of traditional Die Casting also cannot borrow this technology to undertake compound and jump a new chance to extricateoneself from an awkward position. 2, the technology of advantage tradition Die Casting that uses technology of extruding Die Casting on machine of traditional Die Casting and equipment technology are quite perfect already, especially machine of Die Casting of horizontal cold room and craft of horizontal Die Casting, its pressure shoot with plant of model of lock combining a model, have extremely strong craft adaptability. Accordingly, if cannot be united in wedlock with photograph of equipment of traditional Die Casting,crowded Die Casting makes technology, the wide application that restricts it. Step this one pace, crowded Die Casting builds a technology to will appear another branch, this is technology of extruding Die Casting. Change character, in the application on the foundation of machine of traditional Die Casting crowded Die Casting makes a technology, it is technology of extruding Die Casting. According to the characteristic of craft of oneself of extruding Die Casting, undertake be perfectinged accordingly transforming to machine of traditional Die Casting, this equipment is a machine of brand-new extruding Die Casting. 1. The function of craft of Die Casting of correct and comprehensive understanding and machine of traditional Die Casting holds crowded Die Casting to build the principle of craft, on machine of traditional Die Casting the ground uses technology of extruding Die Casting simply is not a tickler, crucial is breakthrough tradition idea. It needs the property that owns to place of machine of traditional Die Casting to have comprehensive and sufficient knowledge, also want to have deep understanding to craft of traditional Die Casting, even cleared the ambiguous understanding of those first impressions are strongest. In fact, the Die Casting machine of uptodate tradition, its function already comparatived all ready, it not only can undertake common Die Casting, still can undertake Die Casting of extruding Die Casting, belt core extruding; Not only can undertake all sorts of low Die Casting is built, poor Die Casting is built, gravity is cast, after increasing evacuating device, still can undertake vacuum sucks Die Casting of extruding of Die Casting of casting, vacuum, vacuum. If the thought is unlocked again a bit, half solid state the technology of treatment, die forging joins to it, form Lian Zhu to connect the craft of forge, also can come true effectively. Have the Die Casting opportunity of many model, its press those who shoot a system fire force, pressing firing rate to spend is " successive stepless is adjustable of " . Low Die Casting is built, poor Die Casting is built, for the craft character that gravity casts, undertake on machine of common Die Casting afore-mentioned craft are to do not have any problems. This kind of mould is installed on Die Casting machine, also not be people in the imagination so costly, if pattern of traditional Die Casting is euqally mixed,get. Regretful is in practice we see relevant application and story hard. This is us an understanding error to machine of traditional Die Casting and craft of traditional Die Casting, idea error and applied error. 2. The characteristic of craft of traditional Die Casting and equipment and machine of as traditional as the adaptability of craft of extruding Die Casting Die Casting are divided kind, one kind is complete hydraulic pressure advocate the crock closes (lock) machine of modular Die Casting, another kind is machine of Die Casting of model of lock of music ancon orgnaization. The equipment that locks up a model as a result of music ancon orgnaization makes cost inferior, this kinds of type on uptodate market already took dominant place. Machine of traditional Die Casting has a main feature, the model that is it names in order to lock up modular force for main body parameter, we often say machine of some Die Casting is how many tons now, point to ton of number of the force that lock up a model namely. And machine of extruding Die Casting, it not only the parameter requirement of force of model having a lock, still must an extruding fills shrink the parameter requirement of force, and parameter of this extruding force or the mainest index. As above, because machine of traditional Die Casting has the type that full-hydraulic and music ancon type differ two kinds, did not part when undertaking traditional and common Die Casting, but if use as,differred when extruding Die Casting. Of extruding Die Casting and common Die Casting depend on respectively, cast is in fill model later, extruding Die Casting increased advocate crock motivation advances the labor situation that has filling shrinking ahead, and common Die Casting just cools naturally, did not fill the labor situation that shrink. Here even fractionize and make clear two concepts, join modular force and lock model force namely (or model weighing a lock fights force) . Force combining a model is the motivation that shows those who advance movable mould place to need is forward, the force that lock up a model is to be resistance to fill model, bilge model what need fight force, it can be a static force only (counterforce) . Accordingly, use technology of extruding Die Casting directly with machine of traditional Die Casting, can use its to join modular force only, also joining modular force only just is a power that boosts ahead. Combine the size of modular force, decided extruding fills shrink the size of force. Accordingly, machine of full-hydraulic tradition Die Casting, its join modular force greatly most is the its greatest power that lock up a model, also can fill as its extruding shrink force. And the largest forward extruding force of machine of Die Casting of music ancon type is equal to his to add up to force of modular oil cylinder to multiply the lever with lock model orgnaization to compare, but also cannot exceed its to lock up modular orgnaization greatly most can susceptive compressive strength. Undertake extruding Die Casting with this kind of equipment, because its add up to position of modular initial stage to did not arrive at those who add up to modular orgnaization to lock up " of " dead center oneself, and extruding is terminative the position just is his the " of " dead center that model of the biggest lock fights force, if be filled than pressing with same Die Casting model, the umbriferous area of the part that can produce decreases somewhat. 3. The extruding with the highest Die Casting of extruding of feature of main body technology that limits crowded Die Casting to build fills shrink to be pressed for common Die Casting about than pressing shoot than the 5-10 that press times. Press with the extrusion ratio of extruding Die Casting measure, uptodate fly a model besides the vertical that transforms with machine of 4 column oil pressure pouring crowded Die Casting is built machine outside according with crowded Die Casting to make index of main body technology, the others device comes true, just still belong to place of traditional Die Casting to belong to craft limits, still not be the crowded Die Casting on real significance is built. This concept, we are it is clear to should be limitted. 4. What with traditional Die Casting machine pressing shoots device to have technology of extruding Die Casting is unworkable the gender is uptodate and traditional no matter Die Casting machine is which kind of orgnaizations that lock up a model, get Pascal's law restrict, of the design press firing force is the force that lock up a model about very one of. Craft of active Die Casting asks to press commonly shoot come in 80MPa roughly than pressing between 130MPa, every 100 tons of force that lock up a model can stand the umbriferous area of Die Casting is made an appointment with 150- - 250 square centimeter. Because squeeze Die Casting to build craft place to ask is,fill shrink press and comparing is not Die Casting than pressing, extruding fills shrink topper than pressing demand comes in 500MPa between 1000MPa, the Die Casting to the runner inside small size, we cannot be adopted with press the means that shoot a crock or assists " of crock of extruding or " pressurization to undertake cooling filling shrinking, must by advocate crock motivation extruding fills shrink to just have actual effect. If true with " essence, fast, means of close "Die Casting undertakes extruding Die Casting, be about to increase inside the dimension that circle a mouth, make have ordinal and caky feature. As a result of inside runner cools at cast first commonly, do not increase inside runner dimension, extruding fills shrink to come true far from possibly. This kind of method to a lot of Die Casting it is inapplicable. If want to achieve afore-mentioned extruding to fill,shrink than pressing, the extruding Die Casting that Die Casting machine can produce umbriferous area, reach only original very one of. The semifinished product that machine of traditional Die Casting produces is original " but " of Die Casting umbriferous area already not quite, decrease again 9 into, it is wasteful apparently, the sense that its use was lost on practice. Uptodate Die Casting machine has Die Casting to fill model the link of " pressurization " of later period, but Die Casting air-tightness blemish remain as before, with increase type to produce small part method of " of car of big Niu La of this kind of " , effect it may not be a bad idea does not go where, alleged " essence, fast, close "Die Casting, still be a pretty name only, will 40 years did not see have materiality progress, produce the commerciality conduct propaganda of manufacturer of aircraft of this kind of Die Casting, pour aggrandizement project technology and the understanding error that use personnel, make the person lost way. 5. The feature of main body technology of the feature of main body technology that understands technology of extruding Die Casting and Die Casting of its powerful extruding of technical economy advantage, it is to reflect " common Die Casting to fill model, crowded Die Casting is built fill shrink " principle, it is to use what machine of existing Die Casting perfects to press shoot a system to undertake full model, use up photograph of fluid of utmost escape metal to fill again at the same time model when Pascal's law is right fill model condition (the spare parts can be filled model area) restrict. This have very important sense, it also is the main feature of craft of extruding Die Casting: What craft of extruding Die Casting emphasizes is to be being satisfied fill model below the condition, use lowest as far as possible fill model mix than pressing speed, thought of this kind of craft, fill to wanting low pressure model Die Casting of all sorts of large large parts and successful implementation belt core is a greatest advantage. This is it can replace low pressure, difference pressing, gravity to cast the reason that reachs foundry technology of moulding of partial belt core. Of craft of extruding Die Casting put forward, extended the range of machine of traditional Die Casting and applicable of Die Casting craft greatly, its great economy still depends on, machine of a traditional Die Casting if with 1. The low pressure of 4Mpa is filled model, 80 the umbriferous area that produces a part was before----100 times, can say, the mould that the workbench of existing equipment can install has how old, can produce how old the spare parts of dimension. With a traditional J1140 complete hydraulic pressure machine of 400 tons of Die Casting is transformed shrink to have 400 tons of extruding to fill at the same time the machine of extruding Die Casting of force, can satisfy hub of the car with extruding average Die Casting, autocycle basically the craft of spare parts of this kind of big norms asked. The craft sex with extruding Die Casting is conjectural, one has the opportunity of extruding Die Casting of 500 tons of force that lock up a model and 500 tons of extruding force at the same time, can cope with the Die Casting that shows Shi Jiucheng above production, the machine of traditional Die Casting that uses 500 tons of above to lock up modular force, already was a very wasteful practice, to factory of small-sized Die Casting, have huge to invest a risk. Place of craft of extruding Die Casting accumulate containing technical economy energy is exclamatory making a person. The factory of extruding Die Casting of a coequal dimensions, its installation cost will can reduce 2/3 above than factory of traditional Die Casting, the casting that its craft adaptability can enclothe the majority outside be being cast except moulding however is caused model. Of technology of extruding Die Casting put forward, the breakthrough on the idea may compare the breakthrough of its technology itself, the meaning is even far-reaching. 6. Of craft of extruding Die Casting and equipment of traditional Die Casting cut the entrance to be with machine of horizontal Die Casting exemple, this kind of traditional equipment need not new raise machine, also can use technology of extruding Die Casting, also can produce extruding Die Casting, the spare parts construction that just produces is a bit simple, the ply dimension precision of the spare parts is restricted certainly. As a result of machine of traditional horizontal Die Casting and extruding of neither one appropriative fills shrink orgnaization, orgnaization combining a model must be assumed at the same time add up to model and extruding to fill shrink function, pattern of uses extruding Die Casting, the punch of the design is must be whole spare parts umbriferous area, essence is " of drift of a " , with open type to squeeze Die Casting to build machine place to use mould likeness, the structure of mould of crowded Die Casting that is a kind of the most traditional, model. Accordingly, on machine of traditional horizontal Die Casting application pushs Die Casting technology, need has controlled his to combine dimension precision of the model. The simplest way, can control " to had controlled the exact position that closes a model in real time through so called " . Increase position of a " through be on Die Casting machine electronic-controlled " switch, make corresponding adjustment to the logistic circuit of Die Casting machine. Die Casting ply precision, be enslaved to be enslaved to this " position is electronic-controlled of switch " can accuse precision. Pass such improvement, craft of whole extruding Die Casting and existing vertical shut a model (drift type mould) press instead fill model crowded Die Casting makes technology very similar. Undertake with machine of common horizontal Die Casting Die Casting is produced squashing, because be to shut a model to fill model, it not only producible more crowded than traditional vertical Die Casting is built machine the model is pouring the part that the method produces complex structure, and because press the crowded Die Casting that shoots a system to than using 4 post oil pressure machine is transformed and also be become,build opportunity is more perfect, it also shuts a model to turn over extrusion Die Casting to invent a method than vertical producible a more complex part, its are complex coefficient and craft of traditional Die Casting are same. 7. The similarities and differences that the mould top of extruding Die Casting gives device and pattern of traditional Die Casting uses machine of traditional horizontal Die Casting to use technology of extruding Die Casting, still having a very different feature is its carry a device on the head. Machine of traditional Die Casting makes semifinished product stays in movable mould commonly, and craft of extruding Die Casting is to stay in movable mould or static model two kinds of circumstances can exist, it has structure, pattern to the model bear force and mould cost produce conclusive effect. The engine of extruding Die Casting that new design produces must mature this problem. Notable is, model of extruding Die Casting assumes high-pressured extruding to fill shrink, it should have higher mechanical strength than model of traditional Die Casting, the design standard that should consult forge tool set is provided undertakes bear intensity of pressure spends a design, what its carry place giving staff on the head to need intensity to also compare pattern of traditional Die Casting is big. It is better to want the intensity that solves mould of extruding Die Casting and stiffness this problem, must simplify the structure of mould of extruding Die Casting, this is about to press craft of extruding Die Casting to undertake be transforminged thoroughly to machine of traditional Die Casting, or use machine of true extruding Die Casting. 3, of the design of machine of new-style extruding Die Casting and machine of traditional Die Casting transform summarize machine of extruding Die Casting is transformed on the foundation of machine of traditional Die Casting, have two kinds of ways: It is the manufacturer that produces Die Casting engine, press the feature of craft of extruding Die Casting, the design produces the engine of extruding Die Casting of all-round with wide adaptability. The opportunity of has force of identical lock model and extruding force extruding Die Casting that Die Casting machine produces manufacturer to design production by this technology train of thought, overall production cost compares machine of common Die Casting only tall 3% the left and right sides. Specific improve plan to be able to consult the patent document related this technology introduces. 2 it is to show some Die Casting manufacturer to to its oneself proper motion of Die Casting machine is transformed. The full-hydraulic that transforms a tradition locks up machine of modular Die Casting to be machine of extruding Die Casting, cost is lowest, it should add lock model orgnaization on equipment only, cost is controlled to 10 thousand yuan in 5000 yuan, volume of equipment model tonnage, differ and not quite. Machine of Die Casting of model of lock of music ancon type can be finished in general machinery plant transform the job. Those who transform charge to be equipment value commonly 5% the left and right sides. Die Casting machine transforms the music ancon type that is a force that lock up a model 500 tons to have the extruding that force of model of 500 tons of locks mixes to fill at the same time for shrink the machine of extruding Die Casting of force, cost makes an appointment with 30 thousand yuan. Machine of Die Casting of two kinds of distinct categories changes the opportunity of extruding Die Casting that create, structure of mould of its extruding Die Casting is met somewhat difference, this is design personnel need is advertent. About the characteristic of mould of extruding Die Casting, will other article introduces. 4, of craft of epilogue extruding Die Casting and equipment technology put forward, make crowded Die Casting built a technology to stride ahead greatly one pace, but it or a newly emerging things, remain to person of the same trades are abounded in practice and rise.
