透视制模法是根据制模过程的不同阶段,分别交替将铸件的合金与型芯视为透明体与不透明体,在透明体中浇注成型的一种制模方法。它是伴随着塑料模与类金属铸模材料的诞生而诞生的一种制模新方法。它建立在传统的木模与塑料模制造方法的基础上,但又与之有着明显的区别。它是八十年代末发达国家的先进厂家普遍采用的一种新制模法,是获得尺寸精度较高铸件的重要手段之一。 Perspective modeling method is based on different stages of the molding process, respectively, alternately casting the alloy and the core as a transparent body and opaque body, casting a transparent body molding method. It is accompanied by the birth of plastic mold and metal mold material and a new method of mold. It is based on the traditional methods of making wooden and plastic molds, but with a clear distinction. It is a new mold making method commonly used by advanced manufacturers in developed countries in the late 1980s and is one of the important means to obtain castings with high dimensional accuracy.
