Computer Aided System for Semiautomatic Injection Mould Design

Abstract

Injection molding field has become one of the most important polymer manufacturing areas. One of the elements that plays a very important role in the injection molding process is the mold from which plastic part is obtained. The quality of the final product, depends highly on the proper design of the mold. A software to design injection molds following a design methodology has been developed. It allows the user both, to follow a suitable design itinerary for the mold design including plates, guiding system, ejection system, sliding cores, etc, and to eliminate the repetitive tasks of drawing the different mold elements. The software has been implemented by using PRO/TOOLKIT functions and a Visual C++ environment, and it is supported by PRO/ENGINEER. The usage of the software saves design time at ante project stage and it can be also used as a tool to check the feasibility of the mold according to the part to be manufactured.
