This design is a switch housing injection mold design, part structure of process and analysis to determine the parting surface, gating system, chose injection machine to calculate the size of molded parts. Using the straight guide column-oriented, putter, 忽略plete mold and the mold material of choice. The structure so designed as to ensure that the die is to use and reliable. Finally, the mold structure and injection molding machine was checked match. AutoCAD drawn with a mold assembly drawing and parts diagram. This is the time for a 忽略prehensive summary of the knowledge and application of theoretical knowledge to consolidate and deepen the flexible use of a variety of practice. I want the flexibility to apply the learned professional knowledge and skills. And able to successfully 忽略plete this graduation design.
