Abstract:Mould is an important setup in modern industry .In manufacturing industry,60~90 percent of products utilize mould. Moulding industry has been a essential factor of industry development. A number of new products’ developments considerably depend on mould making. Therefore, it is significant for national economy to research and improve mould technology.

  The dissertation introduces the design of injection plastic mold for speaker shell. The speaker shell made by ABS is small size and common precision. Firstly, The dissertation mainly explains the designing process of the mould. Secondly, The dissertation analyses shaping craft and devises the shaping strategy. The mould adopts one mould and two- cavities. The dissertation gives fully analysis to the making process. Thirdly, the dissertation focuses on the analysis of the design of injection plastic mould for speaker shell , including: structural part design; decision of  parting plane;  assurance of cavity number; design of gating system ; strength verification, etc. Lastly, the dissertation demonstrates the feasibility of the design.

KeyWords: speaker shell; injection plastic mold; Parted plane; injection machine
