CONCEPTUAL DESIGN OF INJECTION MOULD TOOL FOR INLET CHAMBER OF AN AIR INFLATOR

Abstract

Plastic products can be manufactured by various processes. Injection moulding is one of the techniques used to produce plastic products by forcing the molten plastic material under pressure into a mould, where it is solidified and subsequently released by opening the two halves of the mould. Tool design and development is a specialized and critical area. This paper presents the conceptual design of plastic injection mould tool for inlet chamber of an air inflator, which is used for air filling for the dunnage bags. The material used for the production of the component is ABS (Acrylonitrile-Butadience-Styrene).The technique is incorporated to produce a good quality component considering the ease of manufacturability, assembly and positive ejection of the component with minimum possible time and cost. Designing of mould is carried out by using computer aided designing software Unigraphics. The tool is of two plate, single cavity, stripper plate ejection, cold runner (sprue feed system). Cooling system may not be essential as the component mass is less.
