In the drawing process in order to reduce automobile wrinkling and rupture defect，In view of thematerial for the AA6009 aluminum alloy door inner plate，using the finite element software DYNAFOＲM to carry on the drawing forming numerical simulation and the craft optimization. By setting the sheet blank holder force， drawbead and friction coefficient method，the forming limit diagram ( FLD) and the wall thickness distribution of the plate are measured as the standard. ，prediction and optimization of the cause of forming defects，get the best loading. Then use the three-dimensional modeling software UG to carry on the automobile interior board convex， concave die and the blank holder design and carried on the mold component design，completed the mold assembly and the check. . The result show that set draw bead on die and effective binder force and proper coefficient of friction may reduce the tendency of wrinkling and improve the quality of stamping product. Finally，the use of UG for three-dimensional parts of the drawing and assembly，reduce the time of mold development and test mode cycle.
