Abstract: A plastic injection mold in the standard moldbase was chosen as the base, a framework for rapid design systems was formulated. The significance, object of the modular, and establishing methodologies of modules library were analyzed. Finally, rapid design system for injection mold based on standard moldbase and modular was established. The system can improve the utilization of three-dimensional software, the rate of design, and production efficiency, and shorten the product development cycle. Modern design concept, including the people-oriented, green design was reflected in this system, so it was of certain theoretical and practical application value.

Key words: rapid design system, standard moldbase, modular, injection mould
