Mold design have long relied on the experience and mechanical drawing to complete. Since the 1980s, China's development of computer-aided mold design (cad) technology, which has been recognized, and get used to the fast development. Nineties began to develop computer-aided engineering analysis of the mold (cae) technology, now also for many enterprise applications, it shortens mold manufacturing cycle and improve the quality of mold have a significant role. Some mold enterprise applications cad technology industrial countries, from two-dimensional to three-dimensional design development design, three-dimensional design has reached more than 70%. Most Chinese enterprises still remain at the level of two-dimensional design, three-dimensional design of the enterprise can be less than 20%. cae software application has been more common in foreign and domestic applications is still relatively small, is used to predict the part forming process may occur in relatively low level of defects. Mold design and cad, cae software technology, the future should improve the level of the following aspects: * Mold design database and knowledge base systems; * Mold project planning and design; * Reasonable selection of mold materials and standard parts; * Mold rigidity, strength, design and runner cooling passage;
