【導讀】模具是制造業(yè)的重要工藝基礎,在我國,模具制造屬于專用設備制造業(yè)。國雖然很早就開始制造模具和使用模具,但長期未形成產(chǎn)業(yè)。年代后期,中國模具工業(yè)才駛?cè)氚l(fā)展的快車道。近年,不僅國有模具企業(yè)有了很。大發(fā)展,三資企業(yè)、鄉(xiāng)鎮(zhèn)(個體)模具企業(yè)的發(fā)展也相當迅速。中于精密、大型、復雜、長壽命模具領域。由于在模具精度、壽命、制造周期及。要大量進口模具。整和技術發(fā)展水平的提高。結(jié)構(gòu)調(diào)整方面,主要是企業(yè)結(jié)構(gòu)向?qū)I(yè)化調(diào)整,產(chǎn)品。用、高速切削、超精加工及拋光技術、信息化方向發(fā)展。迅速;股份制改造步伐加快等。從地區(qū)分布來看,以珠江三角洲和長江三角洲為。中心的東南沿海地區(qū)發(fā)展快于中西部地區(qū),南方的發(fā)展快于北方。國內(nèi)模具自配率只有70%左右。其中低檔模具供過于求,中高檔模具自配率。凈進口量最大的國家。目前享受模具產(chǎn)品增值稅的企業(yè)全國只有185家,大多數(shù)企業(yè)仍舊稅負過重。“十一五”期間,中國

  

【正文】 standard letters also must the prioritize, moreover its development speed should quickly to the mold development speed, like this be able unceasingly to raise our country mold standardization level, thus improves the mold quality, reduces the mold production cycle, reduces the cost. Because our country mold product holds the bigger price superiority in the international market, therefore regarding the exportation prospect good mold product also should take key develops. According to the above required quantity big, the technical content is high, represents the development direction, the export prospect good principle choice prioritize product, moreover chooses the product to have at present to have the certain technology base, belongs has the condition, has the product which the possibility develops . According to 十 15 the mold profession development plan, 十 15 the period mold product development mainly has following several kind of the automobile cover mold (1)Ramming mold to occupy The mold total quantity dish with emphasis above 40%. Automobile cover mold mainly for automobile necessary, also includes for the agriculture with the vehicle, the project machinery and the farm machinery necessary cover mold, it has the very big representation in the ramming mold, the mold mostly is large and middle scale, structure plex, the specification is high. For the passenger vehicle necessary cover mold, the request is in particular higher, may represent the ramming mold the level. This kind of mold our country had the certain technology base, already for middlegrade passenger vehicle necessary, but the level is not high, the ability is insufficient, at present satisfying rate only has one about the half. Center the upscale passenger vehicle cover mold main dependence import, has bee the bottleneck which the automobile develops, enormous influence vehicle type development . (2)The precise ramming mold Multi locations level was entering the mold and fine represents the ramming mold development direction, the precision request life request has been extremely high, mainly for the electronics industry, the automobile, the instrument measuring appliance, the electrical machinery electric appliance and so on formed a plete set. These two kind of molds, domestic had the suitable foundation, and has introduced the overseas technology and the equipment, the individual enterprise produces the product has achieved the world level, but the majority of enterprises still had a bigger disparity, the supply total quantity insufficient, the import were very many (3) The largescale precise plastic mold Plastic mold accounts for the mold total quantity 10%, moreover this proportion also is rising. In the plastic mold necessary largescale casts the mold for the automobile and the electrical appliances, necessary models for the integrated circuit seals the mold, for the electronic information industry and the machinery and the packing necessary multilayer, the multi cavities, the multi material qualities, the multicolor precise note , and saves water the agricultural necessary plastic different molding for the new building materials to squeeze out the mold and the pipeline and the nozzle mold and so on, at present although had the suitable technology base and fast is developing, but the technical level and overseas still had a bigger disparity, the total quantity falls short of demand, Every year import amount reaches several hundred million US dollar. (4) The main mold standard to imitate At present domestically to have an greater output the mold standard letter mainly is the mold frame, the guidance, the throughout lever pushes the tube, the elastic part and so on. These products not only the domestic necessary massive need, the exportation prospect very is also good, should continue vigorously to develop. The nitrogen cylinder and the hot flow channel part main dependence import, should raise the level in the existing foundation, forms the standard and organization scale production. (5) The other hightech content molds Occupies in the mold total quantity green 8% pression casting mold, largescale thin wall precise pression casting technology content high, the difficulty is big. The magnesium alloy pression casting mold at present although just started, but the prospects for development were good, have the representation. The meridian rubber tire mold also is the development direction, detachable mold technology difficulty is biggest. With fast takes shape some fast pattern ma king technologies and the corresponding fast economical mold which the technology unifies has the very good prospects for development. These hightech content molds in 10 15 period also should the prioritize.
