单件小批生产及中小型铸造车间约占全国铸造车间总数的80％以上,对于这类车间造型的机械化,是一个难于处理的问题。“发展简易造型单机”,是当前解决这一问题的途径之一。对此,作者从一九七五年起,考虑设计了将震击缸和起模缸合一的三种司气方法,同时,分析探讨了震击缸代替压实缸完成辅助紧实的可行方案,付于实施。限于篇幅,仅将文题涉及部分作如下介绍。 Small single-batch production and small and medium-sized foundry shop accounted for about 80% of the total number of foundries in the country, for the mechanization of such workshops modeling is a difficult problem to deal with. One of the ways to solve this problem is to “develop a simple model and stand-alone machine.” In this regard, since 1975, the author has considered the design of three kinds of gas methods that combine the impact cylinder with the mold cylinder. At the same time, it has analyzed and discussed that the impact cylinder can complete the auxiliary compaction instead of the compaction cylinder Program, to be implemented. Due to space limitations, only the topics involved in the article are described below.
