This paper mainly introduces the method and the process of the injecting mold designing, and analyses the influence of mould shaping structure to the quality of moulds.After the structure analysing of the mould,draw and design the appearance.structure with the UG three dimensional entity designing, then carry on drawing of ejecting mechanism, cooling system of mould, core, mould shelf and design to lead organization,etc.. Core-pulling structure is the emphsis and difficulty of the article. We have used the slanting sliding block side pulls out method , after the analysis which is both economy and effective, and it can solve this question perfectly .
