Several useful functions for injection mold design are prepared for the system. In this paper, one of the most important functions, i. e., the function of automatic generation of cavity and core is discussed and the newly developed algorithm for the function is presented. And also, some examples which are gotten by the actually developed software are shown. The automatic generation of cavity and core is done using the user-defined geometric data such as product shape, blank shape, parting surfaces and shut-off surfaces.
