一、我国快速成形模具技术的应用研究概况快速成形模具技术的研究与开发,我国早在五十年代后期就已经开始了,然而这项技术在我国的广泛应用与发展则是在七十年代中期,至今方兴未艾。快速成形模具在众多的模具门类中已逐渐形成一个专门的分支,大体可分作以下分类: 1.按应用范围分类 (1) 冷冲压用快速成形模具①大型薄板件拉延成形的快速成形模具; First, the application of rapid prototyping mold technology research overview Rapid prototyping mold technology research and development, our country as early as the late fifties has already begun, however, this technology is widely used in our country and development is in the mid-seventies , So far in the ascendant. Rapid prototyping mold in a large number of mold category has gradually formed a special branch, can be broadly divided into the following categories: 1. According to the application range (1) cold stamping rapid prototyping mold ① large sheet metal parts drawing rapid prototyping mold ;
