Design and Manufacture of Plastic Injection Mould Cavity for “Base Cover of Bus Ticketing Machine”

ABSTRACT This has been an opportunity to study, design and manufacture of an Insert Moulding Tool of Base Cover Component. The material of Base Cover being ABS is used for supporting electronic equipment, for issuing tickets to passengers at KSRTC busses. Tool design protocol is on conventional lines, based on tested and tried norms developed through expertise and extensive experience over a number of years and reported in literature. Design of Core and Cavity and other parts to build the Mould Tool for normal working, Creation of detailed manufacturing drawing of all the parts of the tool, 3D Virtual Models is created for effective communication using the software Pro-E Wildfare2. The Core & Cavity were extracted using Pro-E Wildfare2. The 2D-Drawings of the designed tool have been drawn using Auto CAD® 2002. Cost estimation procedure is carried out to predict the cost of a tool to be manufactured before it is actually manufactured. Fabrication is carried out starting from the design of electrodes, process planning and assembly procedures. The report is made complete by including design of electrodes, process planning, and assembly procedure and Component tryouts. Added to this the Component is checked for dimensional accuracy and a note on cost estimation of the tool is included.
