Die history and Design
1 Die history
1.1 Die position in industrial production
Mold is a high-volume products with the shape tool, is the main process of industrial production equipment.
采用模具生產(chǎn)零部件，具有生產(chǎn)效率高、質(zhì)量好、成本低、節(jié)約能源和原材料等一系列優(yōu)點，用模具生產(chǎn)制件所具備的高精度、高復雜程度、高一致性、高生產(chǎn)率和低消耗，是其他加工制造方法所不能比 With mold components, with high efficiency, good quality, low cost, saving energy and raw materials and a series of advantages, with the mold workpieces possess high accuracy, high complexity, high consistency, high productivity and low consumption , other manufacturing methods can not match. 已成為當代工業(yè)生產(chǎn)的重要手段和工藝發(fā)展方向。 Have already become an important means of industrial production and technological development. 現(xiàn)代經(jīng)濟的基礎工The basis of the modern industrial economy. 現(xiàn)代工業(yè)品的發(fā)展和技術水平的提高，很大程度上取決于模具工業(yè)的發(fā)展水平，因此模具工業(yè)對國民經(jīng)濟和社會發(fā)展將起越來越大的作用。
The development of modern industrial and technological level depends largely on the level of industrial development die, so die industry to national economic and social development will play an increasing role. 1989 年 3 月國務院頒布的《關于當前產(chǎn)業(yè)政策要點的決定》中，把模具列為機械工業(yè)技術改造序列的第一位、生產(chǎn)和基本建設序列的第二位 ( 僅次于大型發(fā)電設備及相應的輸變電設備 ) ，確立模具工業(yè)在國民經(jīng)濟中的重要地位。 March 1989 the State Council promulgated "on the current industrial policy decision points" in the mold as the machinery industry transformation sequence of the first, production and capital construction of the second sequence (after the large-scale power generation equipment and the corresponding power transmission equipment), establish tooling industry in an important position in the national economy. 1997 年以來，又相繼把模具及其加工技術和設備列入了《當前國家重點鼓勵發(fā)展的產(chǎn)業(yè)、產(chǎn)品和技術目錄》和《鼓勵外商投資產(chǎn)業(yè)目錄》。 Since 1997, they have to mold and its processing technology and equipment included in the "current national focus on encouraging the development of industries, products and technologies catalog" and "to encourage foreign investment industry directory." 經(jīng)國務院批準，從 1997 年到 2000 年，對 80 多家國有專業(yè)模具廠實行增值稅返還 70% 的優(yōu)惠政策，以扶植模具工業(yè)的發(fā)展。 Approved by the State Council, from 1997 to 2000, more than 80 professional mold factory owned 70% VAT refund of preferential policies to support mold industry. 所有這些，都充分體現(xiàn)了國務院和國家有關部門對發(fā)展模具工業(yè)的重視和支持。 All these have fully demonstrated the development of the State Council and state departments tooling industry attention and support. 目前全世界模具年產(chǎn)值約為 600 億美元，日、美等工業(yè)發(fā)達國家的模具工業(yè)產(chǎn)值已超過機床工業(yè)，從 1997 年開始，我國模具工業(yè)產(chǎn)值也超過了機床工業(yè)產(chǎn)值。 Mold around the world about the current annual output of 60 billion U.S. dollars, Japan, the United States and other industrialized countries die of industrial output value of more than machine tool industry, beginning in 1997, China's industrial output value has exceeded the mold machine tool industry output.
據(jù)統(tǒng)計，在家電、玩具等輕工行業(yè)，近 90 ％的零件是綜筷具生產(chǎn)的；在飛機、汽車、農(nóng)機和無線電行業(yè)，這個比例也超過 60 ％。According to statistics, home appliances, toys and other light industries, nearly 90% of the parts are integrated with production of chopsticks; in aircraft, automobiles, agricultural machinery and radio industries, the proportion exceeded 60%. 例如飛機制造業(yè)，某型戰(zhàn)斗機模具使用量超過三萬套，其中主機八千套、發(fā)動機二千套、輔機二萬套。 Such as aircraft manufacturing, the use of a certain type of fighter dies more than 30,000 units, of which the host 8000 sets, 2000 sets of engines, auxiliary 20 000 sets. 從產(chǎn)值看， 80 年代以來，美、日等工業(yè)發(fā)達國家模具行業(yè)的產(chǎn)值已超過機床行業(yè)，并又有繼續(xù)增長的趨勢。 From the output of view, since the 80's, the United States, Japan and other industrialized countries die industry output value has exceeded the machine tool industry, and there are still rising. 據(jù)國際生產(chǎn)技術協(xié)會預測，到 2000 年，產(chǎn)品盡件粗加工的 75% 、精加工的 50 ％將由模具完成；金屬、塑料、陶瓷、橡膠、建材等工業(yè)制品大部分將由模具完成， 50 ％以上的金屬板材、 80 ％以上的塑料都特通過模具轉(zhuǎn)化成制品。 Production technology, according to the International Association predicts that in 2000, the product best pieces of rough 75%, 50% will be finished mold completed; metals, plastics, ceramics, rubber, building materials and other industrial products, most of the mold will be completed in more than 50% metal plates, more than 80% of all plastic products, especially through the mold into.
