Abstract With the rapid development of the mold, twenty-first century industrial market place, the mold has become a key manufacturing equipment manufacturing various types of industrial finished products can not be indispensable in order to extend the knowledge part of the process, in order to accommodate the work of all needs, the College held a design. The design design is a continuous curved mold lighthouse. On the foundation of this design is just the study is completed stamping die, mold processing and other programs implemented, is for me a comprehensive test level, is to get full use of the knowledge I gained, the same for my knowledge of retrial and testing. According to this example, analysis of the punching process planning components, described mold structure elements and workflow, and ultimately gives the mold design and drawing should pay attention to the problems.
Keywords: die、stamping 、die design .
