In die production, according to the terms of use the standard mold rate rising, and the use of hot runner mold rate is also rising. Production management level of the pany and mold rising with the development of the Sino foreign joint ventures. The molding tool technical development,in a large extent dependent on the quality of mold materials research, standardization of mold, special machine tool equipment,advanced design and manufacturing technology, it is more important for production technology ,mold manufacturing industry develop toward intelligent, highly integrated,work and flexible improve the quality, improve production efficiency, shorten the manufacturing cycle, reduce the cost,enhance the consumption ability is the goal of mold ,the key is the development direction of mold technology and industry in China: of the large, plex, precision and longlife mold design and manufacturing technology, increases the export quantity of mould, reduce imports mold gradually. popularize, extensive application of CAM/CAD/CAE technology, gradually moving toward integration. Integration should be stressed that the information in the modern mold design and manufacturing, should be more integrated stressed people, technology and management. 機(jī)電工程學(xué)院 10 機(jī) 制本三班 學(xué)生 黃進(jìn) 井岡山大學(xué)畢業(yè)設(shè)計(jì)用紙 第 6 頁 共 43 頁 the use of mold standard parts and mold standardization level rate. The use of standard parts of mould standard parts is to pave the way, high usage can reduce manufacturing cycle, die quality get improved. Advanced countries die standardization, mercialization rate is higher than 70%, than China39。s higher than 40%. Take imported from abroad every year die standard parts about the proportion of import charges three percent to eight percent die. plastic injection mold, promotion of water assisted, gas assisted injection molding and injection molding technology, the positive application of hot runner, meet the molding product needs. the analysis of materials and polishing technology of mould, to achieve the specific product requirements. tooling and quick manufacturing dev
