【正文】 s favor and the concerned leader department39。, may suit each kind of black and the nonferrous metal thick sheet processing generally. The life may achieve 525 ten thousand, the production cost is low. 7 molds semifinished materials fast manufacture technology solid casting Because the massive molds are belong to the single unit or the production, the mold semifinished materials manufacture quality and the cycle and the cost to the final mold quality and cyclical and the cost influence are very important. The modern mold semifinished materials widely have used the seeds casting technology, the socalled solid casting is (polystyrene PS either polymethacrylate PMMA) manufactures using the foam plastics replaces traditional the wooden mold or the metal pattern, after the modelling does not have to take out the model, then may the casting, under the foam plastics model high temperature liquid metal function, deflagrate the gasification but to vanish, the molten metal substitution original foam plastics model holds the position, after the condensation forms the casting. 8 other aspects technologies in order to simplify the mold the structural design, reduces the mold cost, reduces the mold manufacture cycle, in domestic and foreign also successively appeared some other aspects new technology application, like trades the mold frame, the ramming unit, the cutting edge builtup welding quickly, inlays the block casting, the nitrogen spring and so on. nitrogen springs on mold application The nitrogen spring is one kind of new elastic function part, replaces the spring, the rubber, the polyurethane or the air cushion with it side, it can accurately provide presses the strength, then may have the greatly initial ball pressure in the small space, does not need pre tightly, is basically hit the pressure basically in the mold entire work process to be constant. The ball pressure size and the working point position may, accurate, conveniently adjust as necessary, simplifies the mold to stretch, nearby the pressure, exdenning isostructuralism, simplifies the mold design, reduces the pattern making cycle, debugs the mold to be convenient, reduces the replacement mold time, enhances the production efficiency. fast trades the mold technology Because product variety increasing, causes the mold in the production the transmutation extremely frequently, how thereupon reduces the ramming equipment the down time, enhances the production efficiency, fast traded the mold technology to receive people39。 On the other hand enterprise in order to satisfy the multi varieties, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The puter, the laser, electronic, the new material, the new technical development, causes the fast economical pattern making technology even more powerful, the application scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more remarkable. The fast economical pattern making technology and the traditional machinefinishing pares, has the pattern making cycle short, the cost is low, the precision and the life can satisfy in the production the operation requirements, is synthesizes an economic efficiency quite remarkable kind to make the mold the technology, summarizes below, has several types to leave. 1 fast prototypes manufactures technology The fast prototype manufacture technology is called RPM, is one kind of new manufacture technology which the 8039。各種快速經(jīng)濟(jì)制模技術(shù)在推廣應(yīng)用過程中也會不斷完善成熟和發(fā)展，由于高新技術(shù)的發(fā)展，各種技術(shù)的復(fù)合與滲透，為適應(yīng)生產(chǎn)中的不同需求，今后必定會形成一些新型、節(jié)約能源、節(jié)約材料的快速制模技術(shù)。隨著商品經(jīng)濟(jì)的發(fā)展，激烈的市場競爭，產(chǎn)品更新?lián)Q代的加速，對快速經(jīng)濟(jì)制模技術(shù)在縮短周期、降低成本，提高精度和延長壽命方面的要求勢必會越來越高。可加工塑料在發(fā)達(dá)的工業(yè)國家應(yīng)用較
