The CATIA CAA secondary development technology was used to develop the motion simulation and interference checking system of multi-station molds for automobile parts. By classifying the mold parts, a template definition method is proposed, which separates the designers from the cumbersome definition of motions, and realizes the rapid definition of the moving parts. The storage of templated data is solved by CATIA customization features, The movement of parts of the freedom to delete, add and re-edit; By analyzing the basic curve and components of the motion parameters obtained drive curve, the use of drive curves to ensure real and effective motion simulation. Compared with the professional simulation software, the system realizes the integration of mold design modification and simulation inspection, and avoids the repeated conversion of the model data. Compared with the simulation module of CATIA platform, the system reduces the repetitive operation of designers in the simulation process. System to enhance the design of multi-station car mold efficiency and shorten the development cycle.
