At present, the mould industry has bee the important basis of the industry of the national economy. The car industry is pillar industry of the national economy, the update mainly depends on the car body development cycles. And the development of key to body automobile covering die design and manufacture. Above that is the top of the car partment cover plate, the subject is using UG design that car trimming mold. The cover of the stamping process, mold design and manufacturing process, debugging and use and other than die, there is the unique. To stamping process is concerned, and that other stamping pared with thin materials, shape plex, and more for threedimensional surface, structure size and surface quality higher characteristic, to get a qualified covering, the key lies in its technology is reasonable. Use of 3 d software to develop parametric die structure, establishing standard parts library to mold for overall drive, can greatly decrease the repetitive work, improve the design efficiency, shorten the design cycle. From the analysis of the above that stamping technology, can see, material thickness of mm above that, belong to the plate material forming, need to pass and delay, trimming and plastic three procedure. Through the UG software that analysis of car, after DL figure pretreatment and thus
