24、uction efficiency is not high, poor economic returns. 模具行業(yè)的生產(chǎn)小而散亂,跨行業(yè)、投資密集,專業(yè)化、商品化和技術(shù)管理水平都比較低。 Mold production industry </p><p>  據(jù)不完全統(tǒng)計(jì),全國現(xiàn)有模具專業(yè)生產(chǎn)廠、產(chǎn)品廠配套的模具車間(分廠)近17000家,約60萬從業(yè)人員,年模具總產(chǎn)值達(dá)200億元人民幣。 According

25、 to incomplete statistics, there are now specialized in manufacturing mold, the product supporting mold factory workshop (factory) near 17 000, about 600 000 employees, annual output value reached 20 billion yuan mold. 但

26、是,我國模具工業(yè)現(xiàn)有能力只能滿足需求量的60%左右,還不能適應(yīng)國民經(jīng)濟(jì)發(fā)展的需要。 However, the existing capacity of the mold and die industry can only meet the demand of 60%, still can not meet the needs of national economic development. 目前,國內(nèi)</p><p

28、China mold is divided into 10 basic categories, which, stamping die and plastic molding two categories accounted for the main part. 按產(chǎn)值計(jì)算,目前我國沖壓模占50%左右,塑料成形模約占20%,拉絲模(工具)約占10%,而世界上發(fā)達(dá)工業(yè)國家和地區(qū)的塑料成形模比例一般占全部模具產(chǎn)值的40%以上。 Calcul

33、地位。 Currently a single cavity, a simple mold cavity 70%, and still dominant. 一模多腔精密復(fù)雜的塑料注射模,多色塑料注射模已經(jīng)能初步設(shè)計(jì)和制造。A sophisticated multi-cavity mold plastic injection mold, plastic injection mold has been able to multi-color

34、preliminary design and manufacturing. 模具平均壽命約為80萬次左右,主要差距是模具零件變形大、溢邊毛刺大、表面質(zhì)量差、模具型腔沖蝕和腐蝕嚴(yán)重、模具排氣不暢和型腔易損等,注射模精度已達(dá)到5um以</p><p>  2、模具工業(yè)技術(shù)結(jié)構(gòu)現(xiàn)狀 3.2 mold Present Status of Technology</p><p>  我國模具工業(yè)目前技

37、el, there is a big gap between both. 在應(yīng)用CAD技術(shù)設(shè)計(jì)模具方面,僅有約</p><p>  缺乏技術(shù)素質(zhì)較高的模具設(shè)計(jì)、制造工藝技術(shù)人員和技術(shù)工人,尤其缺乏知識(shí)面寬、知識(shí)結(jié)構(gòu)層次高的復(fù)合型人才。 Lack of technology of high-quality mold design, manufacturing technology and skilled work

38、ers, especially the lack of knowledge and breadth, knowledge structure, high levels of compound talents. 中國模具行業(yè)中的技術(shù)人員,只占從業(yè)人員的8%~12%左右,且技術(shù)人員和技術(shù)工人的總體技術(shù)水平也較低。 China's mold industry and technical personnel, only 8% of em

42、de special tools, auxiliary materials, and some promotion. 但因材料的質(zhì)量不夠穩(wěn)定,缺乏必要的試驗(yàn)條件和試驗(yàn)數(shù)據(jù),規(guī)格品種較少,大型模具和特種模具所需的鋼材及規(guī)格還有缺口。 However, due to </p><p>  模具加工的輔助材料和專用技術(shù)近年來雖有所推廣應(yīng)用,但未形成成熟的生產(chǎn)技術(shù),大多仍還處于試驗(yàn)摸索階段,如模具表面涂層技術(shù)、模具表面熱

48、后,至今仍不能稱其為一個(gè)獨(dú)立的行業(yè)。 China's mold industry is relatively backward and still could not be called an independent industry. 我國目前的模具生產(chǎn)企業(yè)可劃分為四大類:專業(yè)模具廠,專業(yè)生產(chǎn)外供模具;產(chǎn)品廠的模具分廠或車間,以供給本產(chǎn)品廠所需的模具為主要任務(wù);三資企業(yè)的模具分廠,其組織模式與專業(yè)模具廠相類似,以小而專為主;

49、鄉(xiāng)鎮(zhèn)模具企業(yè),與專業(yè)模具廠相類似。 Mold manufacturer in China currently can be divided into four categories: professional mold factory, professional production outside for mold; products factory mold factory or workshop, in order to supp

50、ly the product works as the main tasks needed to die;</p><p>  模具適宜于中小型企業(yè)組織生產(chǎn),而我國技術(shù)改造投資向大中型企業(yè)傾斜時(shí),中小型模具企業(yè)的投資得不到保證。 Mold is suitable for small and medium enterprises organize production, and our technical tra

51、nsformation investment tilted to large and medium enterprises, small and medium enterprise investment mold can not be guaranteed. 包括產(chǎn)品廠的模具車間、分廠在內(nèi),技術(shù)改造后不能很快收回其投資,甚至負(fù)債累累,影響發(fā)展。 Including product factory mold shop, factory,

93、壓技術(shù),蘇聯(lián)對塑性加工的研究也處于世界先進(jìn)行列。50年代,模具行業(yè)工作重點(diǎn)是根據(jù)訂戶的要求,制作能滿足產(chǎn)品要求的模具。模具設(shè)計(jì)多憑經(jīng)驗(yàn),參考已有圖紙和感性認(rèn)識(shí),對所設(shè)計(jì)模具零件的機(jī)能缺乏真切了解。從1955年到1965年,是壓力加工的探索和開發(fā)時(shí)代——對模具主要零部件的機(jī)能和受力狀態(tài)進(jìn)行了數(shù)學(xué)分橋,并把這些知識(shí)不斷應(yīng)用于現(xiàn)場實(shí)際,使得沖壓技術(shù)在各方面有飛躍的發(fā)展。其結(jié)果是歸納出模具設(shè)計(jì)原則,并使得壓力機(jī)械、沖壓材料、加工方法、梅具結(jié)構(gòu)、
