摘 要
针对对讲机后盖进行了注塑模具设计。通过对塑件进行工艺的分析和比较,最终设计出一副注塑模。该课题从产品结构工艺性，具体模具结构出发，对注塑机的选择及有关参数的校核、模具的分型面、浇注系统、模具成型部分的结构、推出系统、冷却系统进行了设计。同时运用三维pro/E制图软件绘制该模具，与平面图相比更具立体感。

Abstract
This topic is mainly for radio shell mold design, plastic parts through the process of analysis and comparison to the final design an injection mold. Process from the product structure on the subject of, specific mold structure to the sub-surface of the mold, pouring system, the mold forming part of the structure, launch systems, cooling systems, injection molding machine of choice and the parameters of the calibration, are detailed design.At the same time drawing zhe molds use to three-dimensional mapping program of pro/E,this computer graphics system has the impasto compared to the plain view drawing.
Key words：injection mold；system of gating；system of cooling；checking.
