上下射砂造型机采用上下射砂的方式冲砂
上下射砂造型机采用上下射砂的方式冲砂，上下射砂是垂直于型板分型面射砂的，所以，它具有复杂形状的铸型和带较深吊砂形状的型板等都能完好地造型、产品布置不太受限制等特点。而且，由于采用了新型射砂结构，所以大幅度地扩大了所用砂型的适用范围。另一方面，由于上下射砂式操作简单、结构紧凑，所以是大多数铸造厂需要的铸造设备。
1) The upper and lower sand shooting moulding machine adopts the method of sand shooting from top to bottom, and the upper and lower sand shooting is vertical to the parting surface of the moulding plate. Therefore, it has the characteristics of complex shape of the casting mold and the moulding plate with deep suspended sand shape, etc. can be perfectly moulded, and the product layout is not restricted. Moreover, the new sand blasting structure is adopted, so the application scope of the sand mold used is greatly expanded. On the other hand, because of its simple operation and compact structure, it is the casting equipment needed by most foundries.
上下射砂单工位造型机，从造型到下芯、合型、脱箱、铸型推出都在一个工位上进行了的紧凑型造型机。
The single-station molding machine with sand shooting from top to bottom is a compact molding machine, which has been carried out in one position from molding to core-lowering, closing, box-stripping and casting pushing.
2）上下射砂改善了型砂的流动状态，使砂填充达到了均一化。因此无砂堵塞现象，可稳定生产较深及形状复杂的产品。
2) the upward and downward shooting of sand improves the flow state of molding sand and makes the sand filling achieve homogenization. Therefore, no sand blockage can stabilize the production of deeper and more complex products.
3）可减少布置产品时所收到的限制，增加一型件数。
3) it can reduce the restrictions received when arranging products and increase the number of one type
