Abstract With the increasing development of electronic, automotive and aerospace industries, sheet metal materials utilization, light weight, easy operation, etc。 designed to make sheet metal parts are widely used in various industries, sheet metal products can be seen everywhere in life。 Therefore judge mold industry has become a national industrial development of the important indicators。 For growing mold industry, Pro / e, UG, CATIA, SolidWorks and other three-dimensional mapping software constantly updated sound, function more complete, more convenient to use。 Three-dimensional mapping software to visualize the entire design process, the parts can disassemble assemble and retain the middle of the process in order to optimize mold design, mold to promote industrial development play a key role。 In this design, the parts physical measurements, and the use of UG three-dimensional mapping software to draw parts diagram, expand the map。 Through the structure and process of the parts analysis, select multi-position progressive die mold in many species。 Then progressive die design principles and order parts through machining stage design layout diagram actually needed。 Calculate the punching, bending, expansion-type force, determine die pressure center and calculate the convex and concave mold cutting edge size。 Design of progressive die unloading device, positioning device and guide。 Select suitable materials mold parts, the design of its size, with the way, used processing methods。 Select and press feeding device。 Finally, three-dimensional rendering of each part and assembly drawings。 The graduation project is completed。
