With the development of the plastic industry, mold manufacturing in the increasingly high status and die level of technology, has become a national manufacturing measure the level of the important signs, the plastic injecting mold has already become one of the mainly ways of making the plastic ware. This paper describes the injection mold design method and process. First, on the injection mold at home and abroad of the status quo and future development trend of development, and plastic parts of the structure analysis, according Plastics Mold Design structure. Design elements include : injection machine models of choice, forming parts of the design, pouring system, from top design, pumped-lateral agencies, cooling system and die-design, in addition, to other parts injection mold for the simple presentation and design. Which side pulling mechanism design is difficult and brochures on the detailed design, the insight was elaborating in the end of the paper, and the later designing way of the injecting mold was put forward my views and viewpoints.
