Redesign and Finite Element Analysis for Movable Platen of Toggle Type Injection Molding Machine

Abstract

The purpose of the project is to redesign and optimize movable platen of 500T toggle type injection molding machine. The one side of platen is connected to toggle clamps and the mold is connected to the other end of movable platen. The movable platen reciprocates over the four tie-bars, which are located at four corners. The detail design of existing movable platen of 500T is studied thoroughly. Finite Element Analysis is carried out for 500T movable platen in Ansys Workbench 14.5 and the stress values are compared with acceptable criteria.

The aim of the project is to redesign the movable platen by changing the tie-bar distance after analyzing the stress and deflection values with the help of Finite Element Analysis, to improve the reliability of the proposed design. The movable platen is the critical component of injection molding machine. Optimization has been carried out to optimize the weight, which ultimately give machine a competitive edge over the market in terms of cost and design.
