The level of a cuntry’s industry was mostly determined by die & mould technology. But injection die & mould demonstrates its incomparable superiority,more and more.Firstly,this articl introduced the current situation and problems of die & mould technology, and put forward the development trend of die & mould technology. Secondly, take the injection die & mould designing about lid of barrel for exemple, elaborate the detailed process of injection die & mould design. In the design has utilized the advanced CAD/CAM/CAE technology,and has optimized the injection die & mould. Theoretically analyzed the plastic product’s questions in the injection molding. For exemple, plastic product’s shrinkage and warpage were Influenced by the factors about size of gate、injection speed、injection pressure and so on, and then the corresponding solution to be followed.
