一、研究目的及内容粘土砂潮漠造型目前仍占绝大部分,而采用普通气动震压造型机所占的比例比其他类型造型机还是相当大。国外早已广泛使用弹簧式(或气垫式)气动微震压实造型机,国内仅是在一些地方使用,还未普及。就我省而言,此类造型机为数很少,更谈不上得到全面应用。大多数,特别中小厂仍是采用一般震压式造型机。因而对气动微震机构的 First, the research purpose and content Clay sand tide desert shape still account for the vast majority, and the proportion of ordinary pneumatic compression molding machine than other types of molding machine is still quite large. Foreign has long been widely used spring-type (or air-cushion) pneumatic microseismic compaction molding machine, the domestic use is only in some places, not yet universal. In our province, the number of such molding machine is small, let alone be fully applied. Most, especially small and medium-sized factories are still using general compression molding machine. Thus the pneumatic microseismic mechanism
