文 獻(xiàn) 綜 述
摘要 塑料工業(yè)是當(dāng)今世界上增長最快的工業(yè)門類之一，而注塑模具是其中發(fā)展較快的種類，因此,研究注塑模具對了解塑料產(chǎn)品的生產(chǎn)過程和提高產(chǎn)品質(zhì)量有很大意義。模具是制造業(yè)的重要基礎(chǔ)裝備，它是“無以倫比的效益放大器”。沒有高水平的模具，也就沒有高水平的工業(yè)產(chǎn)品，因此模具技術(shù)也成為衡量一個國家產(chǎn)品制造水平的重要標(biāo)志之一。
關(guān)鍵詞 模具 分類 現(xiàn)狀
1 模具工業(yè)在國民經(jīng)濟中的地位
模具是制造業(yè)的一種基本工藝裝備，它的作用是控制和限制材料（固態(tài)或液態(tài)）的流動，使之形成所需要的形體。用模具制造零件以其效率高，產(chǎn)品質(zhì)量好，材料消耗低，生產(chǎn)成本低而廣泛應(yīng)用于制造業(yè)中。
模具工業(yè)是國民經(jīng)濟的基礎(chǔ)工業(yè)，是國際上公認(rèn)的關(guān)鍵工業(yè)。模具生產(chǎn)技術(shù)水平的高低是衡量一個國家產(chǎn)品制造水平高低的重要標(biāo)志，它在很大程度上決定著產(chǎn)品的質(zhì)量，效益和新產(chǎn)品的開發(fā)能力。振興和發(fā)展我國的模具工業(yè)，正日益受到人們的關(guān)注。早在1989年3月中國政府頒布的《關(guān)于當(dāng)前產(chǎn)業(yè)政策要點的決定》中，將模具列為機械工業(yè)技術(shù)改造序列的第一位。[1]
模具工業(yè)既是高新技術(shù)產(chǎn)業(yè)的一個組成部分，又是高新技術(shù)產(chǎn)業(yè)化的重要領(lǐng)域。模具在機械，電子，輕工，汽車，紡織，航空，航天等工業(yè)領(lǐng)域里，日益成為使用最廣泛的主要工藝裝備，它承擔(dān)了這些工業(yè)領(lǐng)域中60％~90％的產(chǎn)品的零件，組件和部件的生產(chǎn)加工。
模具制造的重要性主要體現(xiàn)在市場的需求上，僅以汽車，摩托車行業(yè)的模具市場為例。汽車，摩托車行業(yè)是模具最大的市場，在工業(yè)發(fā)達(dá)的國家，這一市場占整個模具市場一半左右[2]。汽車工業(yè)是我國國民經(jīng)濟五大支柱產(chǎn)業(yè)之一，汽車工業(yè)重點是發(fā)展零部件，經(jīng)濟型轎車和重型汽車，汽車模具作為發(fā)展重點，已在汽車工業(yè)產(chǎn)業(yè)政策中得到了明確。汽車基本車型不斷增加，2005年將達(dá)到170種。一個型號的汽車所需模具達(dá)幾千副，價值上億元。為了適應(yīng)市場的需求，汽車將不斷換型，汽車換型時約有80％的模具需要更換[3]。中國摩托車產(chǎn)量位居世界第一，據(jù)統(tǒng)計，中國摩托車共有14種排量80多個車型，1000多個型號。單輛摩托車約有零件2000種，共計5000多個，其中一半以上需要模具生產(chǎn)。一個型號的摩托車生產(chǎn)需1000副模具，總價值為1000多萬元。其他行業(yè)，如電子及通訊，家電，建筑等，也存在巨大的模具市場。
目前世界模具市場供不應(yīng)求，模具的主要出口國是美國，日本，法國，瑞士等國家。中國模具出口數(shù)量極少，但中國模具鉗工技術(shù)水平高，勞動成本低，只要配備一些先進(jìn)的數(shù)控制模設(shè)備，提高模具加工質(zhì)量，縮短生產(chǎn)周期，溝通外貿(mào)渠道，模具出口將會有很大發(fā)展。研究和發(fā)展模具技術(shù)，提高模具技術(shù)水平，對于促進(jìn)國民經(jīng)濟的發(fā)展有著特別重要的意義[4]。
2 各種模具的分類和占有量
模具主要類型有：沖模，鍛摸，塑料模，壓鑄模，粉末冶金模，玻璃模，橡膠模，陶瓷模等。除部分沖模以外的的上述各種模具都屬于腔型模，因為他們一般都是依靠三維的模具形腔是材料成型[5]。
（1）沖模：沖模是對金屬板材進(jìn)行沖壓加工獲得合格產(chǎn)品的工具。沖模占模具總數(shù)的50％以上。按工藝性質(zhì)的不同，沖模可分為落料模，沖孔模，切口模，切邊模，彎曲模，卷邊模，拉深模，校平模，翻孔模，翻邊模，縮口模，壓印模，脹形模。按組合工序不同，沖模分為單工序模，復(fù)合模，連續(xù)模。
（2）鍛模：鍛模是金屬在熱態(tài)或冷態(tài)下進(jìn)行體積成型是所用模具的總稱。按鍛壓設(shè)備不同，鍛模分為錘用鍛模，螺旋壓力機鍛模，熱模鍛壓力鍛模，平鍛機用鍛模，水壓機用鍛模，高速錘用鍛模，擺動碾壓機用鍛模，輥鍛機用鍛模，楔橫軋機用鍛模等。按工藝用途不同，鍛?？煞譃轭A(yù)鍛模具，擠壓模具，精鍛模具，等溫模具，超塑性模具等。
（3）塑料模：塑料模是塑料成型的工藝裝備。塑料模約占模具總數(shù)的35％，而且有繼續(xù)上升的趨勢。塑料模主要包括壓塑模，擠塑模，注射模，此外還有擠出成型模，泡沫塑料的發(fā)泡成型模，低發(fā)泡注射成型模，吹塑模等[7]。
（4）壓鑄模：壓鑄模是壓力鑄造工藝裝備，壓力鑄造是使液態(tài)金屬在高溫和高速下充填鑄型，在高壓下成型和結(jié)晶的一種特殊制造方法。壓鑄模約占模具總數(shù)的6％。
（5）粉末冶金模：粉末冶金模用于粉末成型，按成型工藝分類粉末冶金模有：壓模，精整模，復(fù)壓模，熱壓模，粉漿澆注模，松裝燒結(jié)模等[8]。
模具所涉及的工藝繁多，包括機械設(shè)計制造，塑料，橡膠加工，金屬材料，鑄造（凝固理論），塑性加工，玻璃等諸多學(xué)科和行業(yè)，是一個多學(xué)科的綜合，其復(fù)雜程度顯而易見。
3 我國模具工業(yè)的現(xiàn)狀
自20世紀(jì)80年代以來，我國的經(jīng)濟逐漸起飛，也為模具產(chǎn)業(yè)的發(fā)展提供了巨大的動力。20世紀(jì)90年代以后，大陸的工業(yè)發(fā)展十分迅速，模具工業(yè)的總產(chǎn)值在1990年僅60億元人民幣，1994年增長到130億元人民幣，1999年已達(dá)到245億元人民幣，2000年增至260~270億元人民幣。今后預(yù)計每年仍會以10℅~15℅的速度快速增長[10]。
目前，我國17000多個模具生產(chǎn)廠點，從業(yè)人數(shù)五十多萬。除了國有的專業(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)等，都得到了快速發(fā)展。其中，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，成為我國國內(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，康佳和威力等知名集團(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)則多集中于沿海工業(yè)發(fā)達(dá)地區(qū)，現(xiàn)已有幾千家[11]。
在模具工業(yè)的總產(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。其中，沖壓模具約占50℅（中國臺灣：40℅），塑料模具約占33℅（中國臺灣：48℅），壓鑄模具約占6℅（中國臺灣：5℅），其他各類模具約占11（中國臺灣：7℅）。
中國臺灣模具產(chǎn)業(yè)的成長，分為萌芽期（1961——1981），成長期（1981——1991），成熟期（1991——2001）三個階段。
萌芽期，工業(yè)產(chǎn)品生產(chǎn)設(shè)備與技術(shù)的不斷改進(jìn)。由于紡織，電子，電氣，電機和機械業(yè)等產(chǎn)品外銷表現(xiàn)暢旺，連帶使得模具制造，維修業(yè)者和周邊廠商（如熱處理產(chǎn)業(yè)等）逐年增加。在此階段的模具包括：一般民生用品模具，鑄造用模具，鍛造用模具，木模，玻璃，陶瓷用模具，以及橡膠模具等[12]。
1981年——1991年是臺灣模具產(chǎn)業(yè)發(fā)展最為迅速且高度成長的時期。有鑒于模具產(chǎn)業(yè)對工業(yè)發(fā)展的重要性日益彰顯，自1982年起，臺灣地區(qū)就將模具產(chǎn)業(yè)納入“策略性工業(yè)適用范圍”，大力推動模具工業(yè)的發(fā)展，以配合相關(guān)工業(yè)產(chǎn)品的外銷策略，全力發(fā)展整體經(jīng)濟。隨著民生工業(yè)，機械五金業(yè)，汽機車及家電業(yè)發(fā)展，沖壓模具與塑料模具，逐漸形成臺灣模具工業(yè)兩大主流。從1985年起，模具產(chǎn)業(yè)已在推行計算機輔助模具設(shè)計和制造等CAD/CAM技術(shù)，所以臺灣模具業(yè)接觸CAD/CAM/CAE/CAT技術(shù)的時間相當(dāng)早[13]。
成熟期，在國際化，自由化和國際分工的潮流下，1994年，1998年，由臺灣地區(qū)政府委托金屬中心執(zhí)行“工業(yè)用模具技術(shù)研究與發(fā)展五年計劃”與“工業(yè)用模具技術(shù)應(yīng)用與發(fā)展計劃”，以協(xié)助業(yè)界突破發(fā)展瓶頸，并支持產(chǎn)業(yè)升級，朝向開發(fā)高附加值與進(jìn)口依賴高的模具。1997年11月間臺灣憑借模具產(chǎn)業(yè)的實力，獲得世界模具協(xié)會（ISTMA）認(rèn)同獲準(zhǔn)入會，正式成為世界模具協(xié)會會員[16]。整體而言，臺灣模具產(chǎn)業(yè)在這一階段的發(fā)展，隨著機械性能，加工技術(shù)，檢測能力的提升，以及計算機輔助設(shè)計，臺灣模具廠商供應(yīng)對象已由傳統(tǒng)的民用家電，五金業(yè)和汽機車運輸工具業(yè)，提升到計算機與電子，通信與光電等精密模具，并發(fā)展出汽機車用大型鈑金沖壓，大型塑料射出及精密鍛造等模具。

(1) manufacturing stampings with traditional metal materials, are gradually being high-strength steel plate, coated steel plating, plastic laminated steel and other composite materials or polymer materials substitution. With the development of materials science, strengthen the research of new materials stamping performance, continuous development and improvement of metal forming technology.
????? (2) fine blanking and semi-fine blanking, hydroforming, spinning forming, explosive forming, electric water forming, electromagnetic forming, superplastic forming, such as technology development and applications, some of the traditional processing methods will be stamping their replaced by punching processing products become more reasonable and more economical. Fine Blanking technology which has been relatively rapid development, Fine Blanking is an advanced manufacturing technology, can be used to replace certain parts machining with high-quality, high efficiency, low consumption, application characteristics of Canton. Gear plate in terms of fine blanking, in ordinary hydraulic fine blanking machine, technique and equipment is simple and precision workpiece. Its sheet metal as raw material, the use of less without cutting the plastic processing methods, one can get the size shape and high precision, low-shear surface roughness of the parts, the use of fine blanking technology known as fine blanking parts, pieces.
(3) With the development of computer graphics technology matures, the field of metal forming in recent years the rise of the computer-aided design (CAD), computer aided engineering (CAE) and computer-aided manufacturing (CAM) technology. The technology of traditional stamping technology changes have had an important impact. Especially the numerical simulation of sheet metal forming technology, so that sheet metal forming technology to rid itself of the "experience" and "qualitative" level, has entered a "scientific" and "quantitative" stage of development. The use of this technology for sheet metal forming process simulation, you can predict metal stamping process flow, stress and strain and thickness distribution, die by the strength and wrinkle, break down, the impact of lines of possible defects and failure mode. This is to optimize process parameters and die structure provides a very effective tool in reducing or even abolishing the test mode process, shorten the product development cycle and reduce the cost of product development plays an increasingly important role, has become the guiding mold design and optimization an important tool.
???? (4) high-speed milling process, both at home and abroad in recent years the development of high-speed milling process to improve the processing efficiency, and access to high surface finish. In addition, high hardness module can also be processed, also has a low temperature rise, thermal deformation of the small advantages. High-speed milling technology, automobile, home appliance industry, a large cavity mold manufacturing has injected new vitality. At present it has more agile, intelligent, integrated direction.
???? (5) die scanning and digitizing system, high-speed scanners and mold scanning system provides a model or in kind from the scan to be processed into the desired model number of the necessary functions, greatly reducing the mold in the development of the manufacturing cycle. Some quick scan system, which can quickly installed in existing CNC milling machine and machining center, the fast data acquisition, automatic generation of a variety of CNC machining process, the CAD data in different formats for the mold manufacturing industry " Reverse Engineering. " Die scanning system has been in the automotive, motorcycle, household appliances and other industries has been successfully applied, I believe in the "Tenth Five-Year" period will play a greater role.
???? (6) high-quality materials and advanced surface treatment technologies, high-quality steel and application of the corresponding surface treatment technology to improve the life of mold it is very necessary. Mold heat treatment and surface treatment can give full play to the die steel material properties of the key link. Mold heat treatment is the development direction of vacuum heat treatment. In addition to improving the mold surface treatment technology should be developed advanced vapor deposition, plasma spraying techniques.
Fourth, stamping machinery manufacturers in the position and characteristics:
Pressing both capable of producing small-size instrument parts, but also capable of producing beams, such as automotive, pressure vessel head for a class of large parts; both capable of producing the general size and shape of the tolerance level of spare parts, also capable of producing precision (tolerances in the micron level ) and the complex shapes of parts. The world's steel production accounted for 60% ~ 70% of the plates, tubes and other profiles, most of which are made after stamping products. Stamping in the automotive, machinery, household appliances, electrical, instrumentation, aerospace, weapons manufacturing, a very important position.
????? Stamping parts of the light weight, thickness, stiffness good. Its size tolerance is guaranteed by the mold, so the quality of stability, in general no longer be used by mechanical cutting. Cold metal stampings and mechanical properties superior to the original blank, smooth surface appearance. Cold stamping tolerance level and surface state is superior to hot-stamping parts [6].
????? Stamping production technology and equipment is growing, with the exception of the use of the traditional mold presses and steel stampings, the hydroforming and spinning forming, superplastic forming, explosive forming, electric water forming, electromagnetic forming a variety of special Stamping technology is also developing rapidly, the press raise the level of skills to a new height. Special metal forming process is particularly suitable for many species of small and medium-sized quantities (or even dozens of) parts production. For ordinary stamping process, to be used in simple mold, low melting point alloy die, die and stamping group flexible manufacturing systems, organizations and more species of small and medium-sized quantities of stamping parts processing.
????? In short, stamping die with high productivity, low processing costs, material utilization high, simple operation, easy to achieve mechanization and automation are a number of advantages. The use of stamping and welding, bonding and other composite process, so that more reasonable structural parts, processing more convenient, you can use relatively simple technology to create more complex structure.
