Design Optimization of Stationary Platen of Plastic Injection Molding Machine Using FEA
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 5
Abstract
Plastic are certainly most versatile of all known materials today and have therefore, established themselves in enviable position from where are not even possible to replaced. Injection molding machine is one of the most widely used method of conversion of plastic into various end products application to wide range of plastic materials from plastic commodity to specialty engineering plastic.In injection molding machine stationary platen play a very important role. During the process generally compressive stress generates at particular regions. As load varies with fast rate there is chance to failure of tie bar rod. Due to heavy mould shape, size of platen also change, that’s increase its weight as well as stress level at certain region and this is not good in practice . This leads to failure of platen or failure of tie rod due to stretching by nut and platen. This create loss of money (Production stop), man (injured due to accident), and material (increase inventory cost). The aim of this project is study about those areas where stress can affect the failure of tie bar due to heavy weight of stationary platen the deflection or misalignment with movable platen. Finally redistribution of stress sothat uniforme stress achive (optimization of platen). This project is including Finite Element Analysis and Design Optimization of a Typical Structural Component of a Plastic Injection Molding Machine. The aim of project is to optimize a typical structural component (stationary platen) by using finite element analysis after checking induced stresses with allowable design stress. Hence design modification of platen is carried out to achieve good strength and cost effectiveness.
