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 developm
4、ent will play an increasing role. 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
5、 equipment and the corresponding 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 included in the “current national focus on encouraging the development of industries,
6、 products and technologies catalog“ and “to encourage foreign investment industry directory.“ 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. All these have fully demonstrated the develop
7、ment of the State Council and state departments tooling industry attention and support. 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, beg
8、inning in 1997, Chinas industrial output value has exceeded the mold machine tool industry 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 radi
9、o industries, the proportion exceeded 60%. 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. From the output of view, since the 80s, the United States, Japan and other industrial
10、ized countries die industry output value has exceeded the machine tool industry, and there are still rising. 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,
11、 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.2 2、TheThe historicalhistorical developmentdevelopment ofof moldmoldThe emergence of mold can be traced
12、 back thousands of years ago, pottery and bronze foundry, but the large-scale use is with the rise of modern industry and developed.The 19th century, with the arms industry (guns shell), watch industry, radio industry, dies are widely used. After World War II, with the rapid development of world eco

From a global perspective, when the United States in the forefront of stamping technology - many die of advanced technologies, such as simple mold, high effici

Multi-die design rule of thumb, reference has been drawing and perceptual knowledge, on the design of mold parts of a lack of real understanding of function. From 1955 to 1965, is the pressure processing of exploration and development of the times - the m

The result is summarized mold design principles, and makes the pressure machine, stamping materials, processing methods, plum with
