Mold Design for a Composite Core-Pulling Mechanism

Abstract:

This work's context is an industrial project aiming the accurate modeling of the injection molding process.The main purpose of this work was to design a mathematical model and computer programs for design analysis in composite core-pulling mechanism. The injection mould with slanted guide pillar for two-step core-pulling from the side of the product effects significantly the quality and efficiency of plastic part. The study is a one-dimensional analysis of secondaryejector mechanism, based on a forward marching technique of solution for the simple structure and high safety and reliability. 3D numerical simulation of the different stages is considered: during processing, anisotropy of the stress state build up affects its mechanical or dimensional properties once the part is ejected. Using the simulation analysis of mechanical system based on Pro/E, the mechanism can solve the problem that plastic parts are difficult to side core pulling in different directions by the use of bevel pillar.
