工作开始时,将芯盒置于工作台上,工作台上升使芯盒与底板压紧。射砂时,打开射压阀,将储气罐中的压缩空气通过射砂筒上的缝隙进入射砂筒内,于是芯砂形成高速的砂流从射砂孔射入芯盒,并将芯砂紧实,而空气则从射砂头和芯盒的排气孔排入大气。可见,射砂紧实是将填砂和紧砂两个工序一并完成,故生产率很高,他不仅用于造芯,也开始用于造型。

At the beginning of the work, the core box is placed on the worktable, and the table is raised to make the core box and the bottom plate pressed tight. When shooting sand, open the shooting pressure valve, the compressed air in the air storage tank enters the shooting sand barrel through the gap on the shooting sand barrel, then the core sand forms a high-speed sand flow from the shooting hole into the core box, and the core sand is compacted, while the air is discharged into the atmosphere from the shooting head and the vent hole of the core box. It can be seen that sand shooting compaction is the completion of sand filling and sand tightening two processes at the same time, so the productivity is very high. It is not only used for core building, but also began to be used for modeling.
