缩短了的

What we designed in this present is an injection mould of a plastic pothook, which mainly including it's holistic configuration and part design, calculation and check of every part of the mould. A software "PRO/ENGINEER" was used in the design process to analyze the rationality of the mould and decrease the design time for obtaining an ideal mould.
