Development of a Runner and Gate Design System for Injection Mold Design based on Unigraphics

This paper describes the runner and gate design capabilities of the RAMEDS system, which is a specialized CAD system for injection mold design, dcvcloped using the application procedure interface of the Unigraphics system. In this system, runners lying on sculptuted partlng surface can be modeled by projecting the runner trajectory on the surface and sweeping a selected cross section along the projcctcd trajectory. In addtion, the system provides solid modeling capabilities for three types of gates currently.
