Mold has become an important means of modern indus
2、trial production and technology development direction. The foundation of the modern economic industry. Modern industrial development and the improvement of technical level, to a large extent depends on the development level of mold industry, so die industry to national economy and social development
3、 will play an more and more important role. In order to adapt to the user for mould manufacturing of high 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 technological progress of
4、mold industry, satisfy all walks of life to mold the base and the urgent need of process equipmentKeywords: mold; modern economy; the development trendDie position in industrial productionMold is a high-volume products with the shape tool, is the main process of industrial production equipment.With
5、mold components, with high efficiency, good quality, low cost, saving energy and raw materials and a series of advantages, with the mold work pieces possess high accuracy, high complexity, high consistency, high productivity and low consumption, other manufacturing methods cannot match. Have already
6、 become an important means of industrial production and technological development. The basis of the modern industrial economy.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 devel
7、opment 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 generatio
8、n 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,
9、 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 developmen
10、t 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, beginn
11、ing 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 radio i
12、ndustries, 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 industrialize
13、d 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, ru
14、bber, 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 intoDie trendMold CAD / CAE / CAM being integrated, three-dimensional, intelligent and network direction(1) Mol
15、d software features integratedDie software features of integrated software modules required relatively complete, while the function module using the same data model, in order to achieve Syndicated news management and sharing of information to support the mold design, manufacture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits. Series such as the UK Delcams software will include a surface / solid geometric modeling, engineering drawing complex geometry, advanced rendering indust
