Finite Element Analysis and Topology Optimization of the Clamping Unit in a Two-Platen Injection Machine

Hua Wei Zhang, Wei Xia, Zhi Heng Wu

Abstract

In this paper, the clamping unit of a two-platen injection molding machine was modeled by Pro/ENGINEER, and was imported to Altair HyperWorks. In HyperMesh module, the finite element model was set up, ANSYS has been used in the finite element analysis of the clamping unit and the deformation and stress results were obtained. Based on the topology optimization of HyperWorks/OptiStruct, recommendations to improve the structure of the clamping mechanism are presented; the results showed that less material was used while its performance was maintained.
