FAMILY MOULD DESIGN FOR QUALITY LEVERS

Abstract

Moulding is a process in which by pouring a molten metal into a mould cavity which is created by keeping the required shape of pattern on the molding sand and allowing the molten metal to solidify by cooling slowly. But in this process we can able to get only one shape of casting, it means shape of the final casting is limited. If we want more number of same design but not identical parts then it is not possible from a single mould, this drawback can be overcome by family moulding. This paper tells how can be able to get more number of same design but not identical parts. In another words we can say that two different parts can be produced from a single mould. This mould is called family mould. Family mould design consists of a complete mould with a few or many different cavity inserts that runs as a multiple part. Hence Family mould design for plastics levers is made here by using injection moulding machine for injection of molten plastic into mould cavity and UGNX5 software for injection mould design for plastic levers.
