The mold is more and more high in manufacturing industry status, the mold technical level has become the important symbol to weigh the level of a national manufacturing industry horizontal. This article mainly introduced the injection mold’s designing’s method and process. First, it introduced the injection mold’ present development situation in the domestic and foreign and the future development tendency, than analyzed this plastic model’s structure, then designed the mold according to the plastic model’s structure. The designing content includes: injection model machine ’choice, designing of components of take shape, designing of the pouring system, designing of goes against system, designing of the side draws out system, designing of the cooling system and the mold, in addition, there is the simple introduction and designing of other mold’s spare parts. The side draws out system is difficulty in the designing, I design it in detail in the instruction booklet .
