Mold is high quality, high efficiency of production, The development cycle takes large share of the whole product development cycle ， shorten the product development cycle
3、 or not has become the key to success， but used widely in industrial engineering today, to shorten the development cycle of mold has become an inevitable trend. The content of this graduation project is to design a set of the cold die to make the rack frame. On the one hand, through the use of natio
4、nal standards and mechanical analysis to design a practical mold； On the other hand, through the use of CAD, Pro/E and other computer software technology to shorten the product development cycle. This can accelerate the progress of the entire process, ocupied the consumer mind market, and accumulate resources for the subsequent price competition between the same products .
