| Abstract: | The two material injection mould process and the structure features of snap-fit were introduced,the mould was designed.In this mould,some special structures,such as delayed mold core pulling,ejection mechanism in order,and hot runner system combined with the general structure of gating system in second injection were used to solve the problem of rotation for cavity.This mould design would improve the bond strength of the two kinds of material and improve the productivity. |
