CONCEPTUAL DESIGN OF TRANSFER MOULD TOOL FOR RUBBER BUMPER SPRING

Abstract

This paper presents the conceptual design of transfer mould for rubber bumper spring, which is used as housing for auto parts. The fundamental aim of the designer is to achieve balance between productivity and design, by optimizing the design, process and manufacturing parameters, which results in the final cost reduction of the mouldings without compromising the quality of the product. The various parameters like processing temperature, pressure, moulding material, parting line selection, mould cooling, ejection system, etc. affects the design of mould and its functions with variation in cost and quality for producing optimized quality mouldings. By varying some of the above said parameters an effort is made to attain a cost effective conceptual design. The suggested material for rubber bumper spring is NR/BR (Natural & Polybutadiene Rubber) blend. Designing of mould is carried out by using computer aided designing software solid works 13.
