所谓聚氨酯橡胶通用模及其冲裁技术,就是利用高分子化合物-聚氨酯或聚氨基甲酸乙酯(统称为聚氨酯)等人造橡胶制造凸模或凹模,并通过一块厚约2～3毫米的切割模板对板料进行冲裁的技术,模具结构如图1所示;该模具除切割模板外,其余为通用零件,在需要制造某种冲压零件时,只需要制作一块与零件外形相同的切割模板即可。 The so-called polyurethane rubber universal mold and its punching technology, is the use of polymer compounds - polyurethane or polyurethane (collectively referred to as polyurethane) and other artificial rubber to make puncher or die, and through a piece of about 2 ~ 3 mm thick cut The template for blanking the sheet metal technology, mold structure shown in Figure 1; In addition to cutting the mold template, the rest of the common parts, when you need to create some kind of stamping parts, only need to make a piece with the same shape cutting template Can be.
