摘 要 Abstract The contents of this graduation project is the electrical box seat mold design, plastic parts through the process of analysis and comparison, the final design of an injection mold. The graduation process from the product structure of the specific structure of the starting mold of the casting mold system, mold forming part of the structure, the top of the system, cooling system, the choice of injection molding machines and checking the parameters, there are detailed design, plastic Injection molding cycle, the maximum is characterized by short, to forming a complex, precise dimensions, such as plastic parts, the adaptability of various plastics, high production efficiency, product quality is stable, easy to automate production. The process of injection molding of plastic materials is to melt into the barrel through the viscous flow of plastics into liquid, high pressure in the plunger or screw driven, the higher the melt through the nozzle into the mold cavity pressure After cooling, the solidification stage, the cooling is formed, and then typing into a mold shaped pieces are plastic parts products. Mainly for the design work is the first analysis of process performance plastics and draw parts diagram, in this design, the use to the side core pulling, so the side core pulling (angle pin and slide) and design, and the Lord, shunt design, the distribution of the mold cavity and to draw part of their plans, the selection and verification mold, injection molding machine such as the selection and verification, the most important part of the mold structure is medium cavity, core of the radial and height of the calculation process, the design process to access large amounts of data, and to the mold assembly and test mode, in which the problems of the mold to improve until the last part meets the design requirements.Keywords: The lid of the maners lamp ; injection mold 前 言 第一章 绪论 ?1.4.2 国内外模具发展状况 现代模具工业有“不衰亡工业”之称。世界模具市场总体上供不应求，市场需求量维持在600亿至650亿美元，同时，我国的模具产业也
