Design and Analysis of Family Mould for Plastic Box

Abstract

Injection molding is one of the growing molding process in the plastic field. It is a cyclic process of forming plastic into a desired shape by forcing the material under pressure into a cavity. The shaping is achieved by cooling (thermoplastics) or by a chemical reaction (thermosets). It is one of the most common and versatile operations for mass production of complex plastics parts with excellent dimensional tolerance. Injection molding is preferred where tight tolerance, good quality and high rate productions are required.The aim of this paper is to model, extract core–cavity and develop injection molding tool for manufacturing a plastic box and also to reduce its warpage Core–Cavity design the mould flow analysis of the component is done using SOLIDWORK software.The tool will design to produce a good quality component considering the ease of manufacturability, assembly and Positive ejection of the component. The tool design should match the machine specification and should be accurate and economical for successful life of a component or product.
