Die history Abstract: the mold is a tool for mass production with the form of a product, is th e main process equipment in industrial production。 Mold has become an important me ans of modern industrial production and technology development direction。 The found ation of the modern economy industry。Modern industrial development and the improv ement of technical level, to a large extent depends on the development level of mold i ndustry, so die industry to national economy and social development will play an mor e and more important role。 In order to adapt to the user for mould manufacturing of hi gh precision, short delivery time, low cost, the urgent request of the modern advanced manufacturing technology is widely used in die and mould industry to accelerate the t echnological progress of mold industry, satisfy all walks of life to mold the base and t he urgent need of process equipment 82235

Die position in industrial production Mold is a high-volume products with the s hape tool, is the main process of industrial production equipment。

With mold components, with high efficiency, good quality, low cost, saving ener gy and raw materials and a series of advantages, with the mold workpieces possess hi gh accuracy, high complexity, high consistency, high productivity and low consumptio n , other manufacturing methods can not match。 Have already become an important means of industrial production and technological development。 The basis of the mode rn industrial economy。

The development of modern industrial and technological level depends largely o n the level of industrial development die, so die industry to national economic and soc ial development will play an increasing role。 March 1989 the State Council promulga ted "on the current industrial policy decision points" in the mold as the machinery ind ustry transformation sequence of the first, production and capital construction of the s econd sequence (after the large-scale power generation equipment and the correspondi ng power transmission equipment), establish tooling industry in an important position in the national economy。

Since 1997, they have to mold and its processing technology and equipment incl uded in the "current national focus on encouraging the development of industries, pro ducts and technologies catalog" and "to encourage foreign investment industry directo

ry。" Approved by the State Council, from 1997 to 2000, more than 80 professional m old factory owned 70% VAT refund of preferential policies to support mold industry。 All these have fully demonstrated the development of the State Council and state depa rtments tooling industry attention and support。 Mold around the world about the curre nt annual output of 60 billion U。S。 dollars, Japan, the United States and other industria lized countries die of industrial output value of more than machine tool industry, begi nning in 1997, China's industrial output value has exceeded the mold machine tool ind ustry output。

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%。 Such as ai rcraft manufacturing, the use of a certain type of fighter dies more than 30,000 units, o f which the host 8000 sets, 2000 sets of engines, auxiliary 20 000 sets。 From the outp ut of view, since the 80's, the United States, Japan and other industrialized countries di e industry output value has exceeded the machine tool industry, and there are still risin

g。Production technology, according to the International Association predicts that in 2 000, the product best pieces of rough 75%, 50% will be finished mold completed; met als, plastics, ceramics, rubber, building materials and other industrial products, most o f the mold will be completed in more than 50% metal plates, more than 80% of all pla 模具历史英文文献和中文翻译:http://www.youerw.com/fanyi/lunwen_96400.html
