一、概况聚氨酯橡胶冲模是以聚氨酯弹性体代替凸模或凹模的一种新型模具,这种模具结构简单、制造周期短、成本低、通用性强。特别是制模用的浇注型聚氯酯橡胶,具有极好的抗压性能,高强度、高弹性同时兼备,且便于切削。聚氨酯冲模的工作原理是:处于封闭状态下的聚氨酯,压缩时将产生较大的单位压力,压力的性质与液体静压相似;冲压时,利用其受压后产生的弹性变形抗力来完成指定的工序。从经济、合理的观点出发,聚氨酯适合于冲裁0.3毫米以下的金属与非金属材料,能得
First, an overview of polyurethane rubber die is a polyurethane elastomer instead of punch or die a new type of mold, the mold structure is simple, short manufacturing cycle, low cost, versatility. In particular, molding with cast-type polyurethane rubber, has excellent compressive properties, high strength, high flexibility both, and easy to cut. The working principle of the polyurethane die is: the polyurethane in the closed state will produce a greater unit pressure when compressed, and the nature of the pressure is similar to that of the liquid hydrostatic pressure; when the pressure is applied, the elastic deformation resistance generated by the pressure is used to complete the specified Process. From an economical and reasonable point of view, polyurethane is suitable for blanking of metal and non-metallic materials up to 0.3 mm,
