This subject is mainly aimed at the design of plastic molds. Through analysis and comparison of the process of plastic parts, an injection mold is finally designed. Starting from the product structure manufacturability and the specific mold structure, the subject has a detailed design for the mold casting system, the mold forming part structure, the ejection system, the cooling system, the selection of the injection molding machine and the check of related parameters. According to the specific parameters, UG is used for modeling, and then CAM is used for mold flow analysis to optimize and improve, and a more excellent design scheme is obtained, avoiding repeated trial mold repair in the later stage. Finally, CAD is used to create a two-dimensional drawing of the mold to determine the processing procedures and process routes of the mold parts. The entire design process shows that the mold can achieve the processing technology required by this plastic part. The main task of the design according to the subject is the design of the injection mold for the bottom plate of the electronic scale scale housing. That is to design a pair of injection molds to produce plastic parts of electronic scale shell bottom plate to achieve automation and increase output.

本课题主要是针对塑料的模具设计,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，对模具的浇注系统、模具成型部分的结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核、都有详细的设计。根据具体参数利用UG进行建模，然后利用CAM进行模流分析优化改善，得到更加优异的设计方案，避免后期重复的试模修模。最后利用CAD出模具的二维图，确定模具零件加工工序和工艺路线等。通过整个设计过程表明该模具能够达到此塑件所要求的加工工艺。根据题目设计的主要任务是电子体重秤仪表外壳底板注塑模的设计。也就是设计一副注塑模具来生产电子秤外壳底板塑件产品，以实现自动化提高产量。

This topic is mainly for the plastic mold design, through the analysis and comparison of plastic parts technology, the final design of a pair of injection mold. Starting from the product structure and the specific mold structure, this project has a detailed design of the pouring system, the structure of the mold forming part, the ejection system, the cooling system, the selection of the injection molding machine and the check of the relevant parameters. According to the specific parameters, UG is used to model, and then cam is used to optimize and improve the mold flow analysis, so as to get more excellent design scheme and avoid repeated mold test and repair in the later stage. Finally, the two-dimensional drawing of the die is drawn by CAD, and the processing procedure and process route of the die parts are determined. The whole design process shows that the mold can meet the processing technology required by the plastic part. The main task of the design is to design the injection mold for the bottom plate of the shell of the electronic scale. That is to say, a pair of injection mold is designed to produce the plastic products of the shell bottom plate of the electronic scale, so as to realize the automation and increase the output.
