Abstract
SMDS which stands for Sony Mold Design Simulator has been developed as a part of an integrated CAD system for injection mold design. This paper describes the prototype system of SMDS, and some examples that are applied to the actual injection mold design are presented. SMDS has been developed to realize the system that can process the geometric data of a mold, based on CSG solid modeler TIPS-1 system. However, there are some future subjects, i.e., physical analysis, simulation of mold flow and so on. These problems should be solved using the model generated in SMDS in the near future. In SMDS, the process of mold design is done by interactive operations and several useful functions for mold design, i.e., shrinkage process, automatic generation of cavity and core, drafting process, and dimensioning and tolerancing, are prepared. Additionally, SMDS has an interface to a 2-D drafting system that can generate complete drafts using interactive operations.
