DESIGN, OPTIMIZATION AND FINITE ELEMENT SIMULATION OF DIE STRUCTURE IN PLASTIC INJECTION MOULD

Abstract

A die is a comprehensive tool used in manufacturing industries to cut or shape material mostly using a press. Like molds, dies are generally tailored to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology. The Aim of this thesis work is to optimize the weight and cost of the injection mold by removing undesirable materials and using low cost materials at non-stress region areas. A general large size model will be prepared to design the mold structure using theoretical method. Complete level of mold parts and assembly will be prepared to conduct analysis. Structural analysis will be conducted on mould to find stress locations and non-effective locations. Modifications will be done on mold according to obtained results. Finite element simulation will be carried out on modified mold for evaluation and various materials will be applied in ANSYS at non- stress affected areas to reduce the cost. Conclusion will be made from the obtained results along with comparison tables / charts. Keywords: Die, Finite element simulation, mold parts.
