ABSTRACT The Objective of work involves design and manufacture of injection mould for Lead Acid Battery Container for its application in trains. The battery is subject to various factors like temperature and pressure. Thus, we have made considerable improvements to the battery container design which includes: In essence, we have designed the container of the battery, made an exhaustive analysis through different software on the design and finally manufactured the injection mould for the battery container. With respect to the design of the container, the honeycomb structure has been implemented with changes to the rib thickness. The results obtained have been promising with increase in strength and life of component, reduced maintenance and less space used. A Moulding Simulation of the battery container has been done to optimize the part quality like fill balance, injection pressure, clamping force & deflection pattern. Keywords: 16V 120AH Lead Acid Battery, battery container, injection pressure, clamping force & deflection pattern.
