Abstract
Eliminating the under-cut caused by interference between a mold and a product in designing a mold for injection molding processes is a very important problem. In general, the under-cut problem can be avoided by side cores which are the principal members of a mold assembly. In this research, a procedure has been developed by which the side cores and the corresponding core and cavity plates of a mold are generated after identifying the mold faces to prevent product faces from moving while being discharged. The characteristic features of the procedure suggested in this paper are as follows. One is that the interference faces between the product and the mold are derived from the core plate (or cavity plate) alone without considering the product together. The other is that the algorithm in the designing of side cores and modifying molds is very efficient because it uses Euler operations instead of Boolean operations.
