62、產(chǎn)、省料、低成本等特點，現(xiàn)已在國民經(jīng)濟(jì)各部門，特別是汽車、拖拉機、航空航天、儀器儀表、機械制造、家用電器、石油化工、輕工日用品等工業(yè)部門得到極其廣泛的應(yīng)用。</p><p>　　現(xiàn)在，模具技術(shù)已成為衡量一個國家產(chǎn)品制造水平的重要標(biāo)志之一，研究和發(fā)展模具技術(shù)，對于促進(jìn)國民經(jīng)濟(jì)的發(fā)展有著特別重要的意義。模具工業(yè)能促進(jìn)工業(yè)產(chǎn)品生產(chǎn)的發(fā)展和質(zhì)量的提高，并能獲得極大的經(jīng)濟(jì)效益，因此引起各個國家的高度重視和贊賞。在日本，模具

63、被譽為“進(jìn)入富裕社會的原動力”，在德國則冠以“金屬加工業(yè)中的帝王”，在羅馬尼亞視為“模具就是黃金”。因此可以斷言，隨著工業(yè)生產(chǎn)的迅速發(fā)展，模具工業(yè)在國民經(jīng)濟(jì)中的地位將日益提高，模具技術(shù)也會不斷發(fā)展，并在國民經(jīng)濟(jì)發(fā)展過程中發(fā)揮越來越重要的作用。</p><p>　　模具是高科技含量的產(chǎn)品，是專門為工業(yè)生產(chǎn)服務(wù)，并用于特定產(chǎn)品生產(chǎn)而被特殊制作的工藝裝備，隨著工業(yè)產(chǎn)品向多樣化發(fā)展，模具生產(chǎn)從形狀、尺寸、數(shù)量、材料、結(jié)構(gòu)

64、、精度、使用條件及壽命等方面，向著多樣化發(fā)展的傾向也日趨明顯。模具基本上是按訂貨合同單件生產(chǎn)，因此，模具產(chǎn)品的多樣性及單件生產(chǎn)的技術(shù)特點十分突出。所以，工廠的設(shè)計、工藝、工藝裝備和管理等，都要適應(yīng)這個技術(shù)特點。大部分精密復(fù)雜模具都需要高精度機床加工，檢測設(shè)備要求精密度更高。模具加工技術(shù)集中了機械、電子乃至化學(xué)和光學(xué)等工業(yè)技術(shù)的精華。同時，模具對熟練技工的依賴程度遠(yuǎn)比其他加工業(yè)要大。因此，技術(shù)的先進(jìn)性及對熟練技巧的依靠性也是模具產(chǎn)品的技術(shù)

65、特點。隨著技術(shù)的快速發(fā)展，特別是信息技術(shù)等高新技術(shù)在模具設(shè)計制造上的應(yīng)用日漸廣泛和高新技術(shù)對模具提出的要求越來越高，模具的高新技術(shù)特點將日益明顯，而對熟練技巧的依靠性將逐步淡化。</p><p>　　作為工業(yè)生產(chǎn)基礎(chǔ)工藝裝備，模具在國民經(jīng)濟(jì)中占有重要的地位，模具技術(shù)也已成為衡量一個國家產(chǎn)品制造水平的重要標(biāo)志之一。80年代以來，我國模具工業(yè)發(fā)展十分迅速。國民經(jīng)濟(jì)的高速發(fā)展對模具工業(yè)提出了越來越高的要求，也為其發(fā)展提

66、供了巨大的動力。這些年來，中國模具工業(yè)一直以15%左右的增長速度快速發(fā)展。目前，中國17000多個模具生產(chǎn)廠點，從業(yè)人數(shù)約50多萬。1999年中國模具工業(yè)總產(chǎn)值已達(dá)245億元人民幣。工業(yè)總產(chǎn)值中企業(yè)自產(chǎn)自用的約占三分之二，作為商品銷售的約占三分之一。</p><p>　　在模具工業(yè)的總產(chǎn)值中，沖壓模具約占50%，塑料模具約占33%，壓鑄模具約占6%，其它各類模具約占11%。改革開放以來，中國模具工業(yè)企業(yè)的所有

67、制成分也發(fā)生了巨大變化。除了國有專業(yè)模具廠外，其他所有制形式的模具廠家，包括集體企業(yè)、合資企業(yè)、獨資企業(yè)和私營企業(yè)，都得到了快速發(fā)展，集體和私營的模具企業(yè)在廣東和浙江等省發(fā)展得最為迅速。例如，浙江寧波和黃巖地區(qū)，從事模具制造的集體企業(yè)和私營企業(yè)多達(dá)數(shù)千家，成為國內(nèi)知名的“模具之鄉(xiāng)”和最具發(fā)展活力的地區(qū)之一。在廣東，一些大集團(tuán)公司和迅速崛起的鄉(xiāng)鎮(zhèn)企業(yè)，為了提高其產(chǎn)品的市場競爭能力，紛紛加入了對模具制造的投入，例如科龍、美的、康佳和威力等集

68、團(tuán)都建立了自己的模具制造中心。中外合資和外商獨資的模具企業(yè)多集中于沿海工業(yè)發(fā)達(dá)地區(qū)，現(xiàn)已有幾千家。例如，江蘇無錫的微研有限公司為一日本獨資企業(yè)，員工有200余人，擁有精密數(shù)控模具加工設(shè)備60余臺，1998年其模具產(chǎn)值超過2億元</p><p>　　中國模具工業(yè)的技術(shù)水平近年來也取得了長足的進(jìn)步。目前，國內(nèi)已能生產(chǎn)精度達(dá)2微米的精密多工位級進(jìn)模，工位數(shù)最多已達(dá)160個，壽命1～2億次。在大型塑料模具方面，現(xiàn)在已能生

69、產(chǎn)48英寸電視的塑殼模具、6.5Kｇ大容量洗衣機的塑料模具，以及汽車保險杠、整體儀表板等模具。在精密塑料模具方面，國內(nèi)已能生產(chǎn)照相機塑料模具、多型腔小模數(shù)齒輪模具及塑封模具等。在大型精密復(fù)雜壓鑄模方面，國內(nèi)已能生產(chǎn)自動扶梯整體踏板壓鑄模及汽車后橋齒輪箱壓鑄模。在汽車模具方面，現(xiàn)已能制造新轎車的部分覆蓋件模具。其他類型的模具，例如子午線輪胎活絡(luò)模具、鋁合金和塑料門窗異型材擠出模等，也都達(dá)到了較高的水平，并可替代進(jìn)口模具。</p>

70、;<p>　　雖然中國模具工業(yè)在過去十多年中取得了令人矚目的發(fā)展，但許多方面與工業(yè)發(fā)達(dá)國家相比仍有較大的差距。例如，精密加工設(shè)備在模具加工設(shè)備中的比重還比較低，CAD/CAE/CAM技術(shù)的普及率不高，許多先進(jìn)的模具技術(shù)應(yīng)用還不夠廣泛等等。特別在大型、精密、復(fù)雜和長壽命模具技術(shù)上存在明顯差距，這些類型模具的生產(chǎn)能力也不能滿足國內(nèi)需求，因而需要大量從國外進(jìn)口。</p><p>　　但是，由于我國的模具

71、行業(yè)起步較晚，與國外相比，仍存在不小的差距，主要體現(xiàn)在：產(chǎn)需矛盾：隨著工業(yè)發(fā)展水平的不斷提高，工業(yè)產(chǎn)品更新速度的加快，對模具的需求越來越大。無論是數(shù)量還是質(zhì)量都無法滿足國內(nèi)市場的需要，只達(dá)到70％左右。造成矛盾突出的原因是模具企業(yè)的專業(yè)化、標(biāo)準(zhǔn)化程度低，生產(chǎn)周期長。另外，設(shè)計和制造工藝水平還不能完全適應(yīng)發(fā)展的需要。 </p><p>　　企業(yè)結(jié)構(gòu)不合理：我國很多模具生產(chǎn)能力集中在各主機廠的模具分廠或車間內(nèi)，模具的

72、商品化程度低，而國外70％以上都是專業(yè)模具廠，且走的是“小而精”的道路，因此生產(chǎn)效率和經(jīng)濟(jì)效益俱佳。 </p><p>　　產(chǎn)品水平 ：衡量模具的產(chǎn)品水平，主要有模具加工的制造精度和表面粗糙度，加工模具的復(fù)雜程度，以及模具的制造周期和使用壽命。而這幾項指標(biāo)與國外相比的差距都十分明顯。 </p><p>　　此外，模具工業(yè)的整體裝備水平也存在相對落后，利用率低的現(xiàn)象。高素質(zhì)的模具技術(shù)人才缺

73、乏，產(chǎn)品的綜合開發(fā)能力還急需加強。 </p><p>　　針對不足和模具市場巨大的潛力，根據(jù)我國模具工業(yè)的現(xiàn)狀，并聯(lián)系國際先進(jìn)水平，中國模具工業(yè)協(xié)會協(xié)助政府制定了我國模具行業(yè)“十五”發(fā)展規(guī)劃，確定模具工業(yè)重點發(fā)展領(lǐng)域有三方面：一是對整個模具行業(yè)發(fā)展有重要影響的主要模具標(biāo)準(zhǔn)件；二是技術(shù)含量高，反映模具制造水平和發(fā)展方向的模具；三是目前大量進(jìn)口的中高檔模具。重點發(fā)展的模具產(chǎn)品主要有：模架，包括冷沖模架、塑料模架和壓鑄

74、模架等；模具導(dǎo)向件，包括導(dǎo)柱、導(dǎo)套、導(dǎo)板及無油潤滑導(dǎo)向件等；推桿、推管，包括塑料模用及壓鑄模用的異型推桿等；熱流道元件，包括內(nèi)熱式、外熱式、閥式和管式等；彈性元件，包括矩形彈簧、聚氨酯彈性體和氮氣缸等；小型標(biāo)準(zhǔn)件，包括標(biāo)準(zhǔn)凸凹模、澆口套、定位圈和拉鉤等；汽車覆蓋件模具，特別是轎車所需的覆蓋件模；精密沖壓模，包括多工位級進(jìn)模、厚板精沖模和硬質(zhì)合金多功能復(fù)合模等；大型塑料模，包括汽車飾件模和家電塑殼模等；精密塑料模，包括塑封模和多層多腔、多

77、校開展模具技術(shù)的研究和開發(fā)。目前，從事模具技術(shù)研究的機構(gòu)和院校已達(dá)30余家，從事模具技術(shù)教育的培訓(xùn)的院校已超過50余家。其中，獲得國家重點資助建設(shè)的有華中理工大學(xué)模具技術(shù)國家重點實驗室，上海交通大學(xué)CAD國家工程研究中心、北京機電研究所精沖技術(shù)國家工程研究中心和鄭州工業(yè)大學(xué)橡塑模具國家工程研究中心等。經(jīng)過多年的努力，在模具CAD/CAE/CAM技術(shù)、模具的電加工和數(shù)控加工技術(shù)、快速成型與快速制模技術(shù)、新型模具材料等方面取得了顯著進(jìn)步；在
