成型模具包括塑料模、胶木模、粉末冶金模和橡胶模等简称为型模,型模种类虽多,但有其共同特点,它们都是由成型零件与结构零件所组成。型模的成型零件形状一般比较复杂,尺寸和配合精度要求比其它类型模具稍高,光洁度要求也较高。因而,成型模具热处理主要是保证成型零件热处理变形小,对表面光洁度的影响小。有些型模,常规热处理无法满足这些要求,不得不牺牲其寿命要求而采用调质处理后再加工使用的方法。成型模具热处理是模具热处理中十分重
Molding molds include plastic molds, bakelite molds, powder metallurgy molds and rubber molds, which are simply referred to as molds. Although the number of molds is large, there are common features, all of which are composed of molded parts and structural parts. The shape of the mold parts are generally more complex shape, size and precision with the requirements of slightly higher than other types of mold, the finish is also higher. Therefore, the forming mold heat treatment is mainly to ensure that the forming parts heat treatment deformation is small, the impact on the surface finish small. Some molds, conventional heat treatment can not meet these requirements, have to sacrifice their life expectancy and the use of quenched and tempered and then processed using the method. Forming die heat treatment is very heavy mold heat treatment
