Design and Analysis of the Sleeve Ejection System in Injection Molding Die for Trolley Wheel

Abstract

Plastic is a commonly used engineering material. Properties like availability, less weight, moldability and corrosion resistance are a few among many desirable properties, due to which most of our usable products are made of plastic. This vital use encourages manufacturing industries to make plastic products in large scale. The industries are able to meet this demand and supply requirement, using various methods of processing plastics. All the methods and tools for processing plastics contribute to mass production. Injection molding dies are one among the many tools used for processing plastics to the required shape. Usually it is very easy to learn and perform the injection molding method to obtain plastic products. But to achieve quality components in mass production, one needs proper implementation of each die-set element in an injection molding die. Ejection of component from the die cavity is one phase in injection molding process and it has similar importance like all other phases. This paper aims at implementation of sleeve ejection system for plastic trolley wheels. Software used for modeling of parts is UG Nx 9.0 and that for the simulation of process parameters is Autodesk Moldflow Adviser 2015. Stress and deformation analysis is done by ANSYS 16.0 version.
