Abstract：

Automatic change of parts with geometric association in product structure is realized in associated design, and geometric consistency of change between parts is maintained. However, design quality after associated change cannot be guaranteed. Therefore, for die and other products with complex structure, an associated design method was put forward, and the influences of changed geometric parameters on quality of die design were expressed by checking knowledge. After the associated changes of parts, the changed die design was checked automatically by checking knowledge in order to make adjustments in time and ensure that the internal rationality of die design was not destroyed by the associated change. Furthermore, the types of part association, representation of checking knowledge and process of associated design based on checking knowledge in the die design were described, and an example of associated design change in drawing die was given. Finally, the validity of this method was verified by application of drawing die design in a stamping enterprise.
