阐述了适用于多品种、小批量生产的金属树脂模具敏捷制造技术,包括快速成型的原理,适合于转化原型零件为“金属树脂”模具的各种模具材料配方的对比试验,从硬度、耐磨性、拉伸强度和线膨胀系数等几个方面得出了适宜于低熔点塑料模具和板料拉伸模的配方。介绍了基于RP技术的金属树脂模具的快速制造过程,并对其关键工序,如设计制造原型零件、原型零件表面处理、分型面选择、凸凹模的浇注等进行了论述,最后分析了这种快速制模方法的特点。
This paper describes the agile manufacturing technology of metal resin mold, which is suitable for multi-species and small-batch production. It includes the principle of rapid prototyping, the comparative test of various mold material formulations that convert prototype parts into “metal resin” mold, Sexual, tensile strength and coefficient of linear expansion and so on several aspects have drawn suitable for low melting point plastic mold and sheet stretching die formula. This paper introduces the rapid manufacturing process of metal resin mold based on RP technology and discusses the key processes such as the design and manufacture of prototype parts, the surface treatment of prototype parts, the selection of parting surface and the pouring of punch and die. Finally, Features of rapid prototyping methods.
