采用粘土砂一次铸型生产铸件,在最近的年代里仍然占优势。因此有必要对高功率和高生产率的自动造型机的无冲击震击和震压过程进行研究,研究它的理论和计算方法。近些年来,在国内先进的汽车厂里,为了制造名目繁多的中型铸件,采用美国SPO公司、西德KW公司和其它公司制造的自动造型线。作为过程自动化的工艺基础在这些自动线上应用压实的同时带有无冲击震动或予震的方法来紧实高强度的铸型。自动造型机震压机构 The use of a clay mold for the production of castings has remained dominant in recent years. Therefore, it is necessary to study the shock-free shock and compression process of high-power and high-productivity automatic molding machines and to study its theory and calculation methods. In recent years, in the state-of-the-art automobile factories, in order to manufacture a wide range of medium-sized castings, automatic modeling lines made by SPO Corporation of the United States, West Germany KW Company and others are used. As the basis for the process automation, high-strength molds are compacted on these automatic line-based compacts with shock-free or earthquake-free methods.
