摘　　要：介绍了一种新发明的气冲气推成形触头造型机实砂机构。它于同一工位、同一工序、用同一动力,实现了气冲紧实与成形触头冲击紧实同时并举。阐述了其实砂过程及实砂机理。试验表明,气冲气推成形触头造型机的实砂效果十分理想,砂型紧实度高而且均匀,完全克服了目前单纯气冲造型技术中存在的弊端,拓宽了气冲造型机的适用范围。这是一种机构简单、投资少、高速、高效、低能耗的造型实砂机构。The sand compaction mechanism of air impact molding machine combined with an air-pushed contour squeeze head, which was recently invented, is demonstrated. For the new machine, air impact compaction and impact compaction of the air-pushed contour squeeze head are simultaneously carried out, and these two types of compaction are performed at the same working place, in the same working procedure, and with the same compressed air power. The process and mechanism of sand compaction are elucidated. The experimental results indicate that the sand compaction effects of this new type of air impact molding machine are ideally perfect, high and uniform mold compactability being obtained. This new air impact molding machine completely overcomes the disadvantages of the present single air impact molding machines, and greatly extends the application scopes of air impact molding technology. And it is a new molding machine of simple design, high speed, excellent efficiency, lower energy consumption and smaller investment.
