塑模典型特征的电极设计及加工技术
Electrode Design and Machining Technology of Typical Characteristics of Plastic Mold
以某款额温枪模具型芯制造为例,开展电火花特种加工中典型特征电极的设计研究,并设计出各类特征电极。通过对零件结构、加工精度要求及放电间隙等多因素的综合分析,提出基于工艺特征的小电极合并与复杂轮廓拆分电极策略。基于铜质电极材料性能,以难加工电极结构为例,介绍数控加工技术,提出工艺规划及加工要点。模具制造完成后,生产的产品已通过客户验收,表明该研究的应用效果良好。
Taking the manufacturing of a core mold for a certain type of forehead thermometer as an example, a design study of typical feature electrodes in electrical discharge machining was conducted, and various types of feature electrodes were designed. Through a comprehensive analysis of multiple factors such as part structure, machining accuracy requirements, and discharge gap, a strategy for merging small electrodes based on process features and splitting complex contour electrodes was proposed. Based on the properties of copper electrode material, a difficult-to-machine electrode structure was used as an example to introduce numerical control machining technology and put forward process planning and machining points. After the mold manufacturing was completed, the produced products passed the customer's acceptance, indicating that the application effect of the study was good.
