1973年我厂参照国外专利,设计和制造了救护车前围外板等较大型的覆盖件拉延模具,其模具型腔均用6101号环氧树脂等材料浇注。几年来的生产实践证明,效果良好。今年一季度我们综合了塑料模的专利,又设计和制造了CD130汽车车门外板成型模具(如图2),现已投入生产,CD130汽车门外板外形如图1。实践证明:环氧树脂塑料模具在经济、技术效果方面有下列优点:(1)以铸造代替机械加工,定型方便,能缩短模具生产周期,便于成批生产。(2)能保证多型腔模具的内型腔和外表形状的同
In 1973, with reference to foreign patents, our factory designed and manufactured a larger cover drawing die for the front cover of the ambulance, and the mold cavities were all cast with 6101 epoxy resin and other materials. Years of production practice has proved effective. In the first quarter of this year, we integrated the plastic mold patent, and designed and manufactured the CD130 automobile door panel forming mold (Figure 2). The CD130 car door panel has been put into production. Practice has proved that: Epoxy plastic mold in the economic, technical effects have the following advantages: (1) instead of machining casting, stereotypes convenient, can shorten the mold production cycle, easy to mass production. (2) to ensure that the multi-cavity mold cavity and appearance of the same shape
