1.采用了新型多功能下压式直冲射砂气包，实现了高压气流吹均压射砂，环形芯盒模腔可得到均实充砂，有效地保证了砂芯的结构强度。

1. a new type of multi-function down pressure direct shooting sand gas package has been adopted to achieve high pressure air blowing in uniform pressure shooting sand, and the ring core box cavity can be filled with solid sand, effectively ensuring the structure strength of the sand core.

2.采用了移动式浮动射头与吹气板，加砂位与射砂位分开，在避免了加砂阀跑砂的同时实现了射头下压射砂及吹气板下压吹气（工作台及芯盒不动），降低了机器运行能耗，缩短了运行周期。

2. the moving floating head and blowing board are used, and the sand position is separated from the sand shooting position. At the same time, the sand of the sand valve and the blow air under the blow board (the worktable and the core box are not moved) can be avoided at the same time, which reduces the running energy of the machine and shortens the operation period.

3.采用了全新的脱模出芯方式：在开模的同时芯棒下抽，砂芯由底板直接送出。其明显优点是：砂芯受力合理，脱模快，取芯方便。

3., a brand-new demoulding and core pulling method is adopted: under the opening of the mould, the core is drawn under the mandrel, and the sand core is directly sent out from the bottom plate. Its obvious advantage is that the sand core is reasonable in force, quick in mold release and convenient in core pulling.

4.模具安装空间及开模行程在一定范围内无级可调，有效避免了大马拉小车的现象，适应了规格跨度较大的系列砂芯生产。大型射芯机的使用范围扩大到DN80-1000,降低了工程建设投资。

The 4. mold installation space and the open die stroke are stepless in a certain range, effectively avoiding the phenomenon of the big Mara car, and adapting to the production of a series of sand core with a large span. The use of large core shooters has been extended to DN80-1000, reducing investment in engineering construction.

5.机器整体结构紧凑，便于封闭，废气收集率高，环保性好。

5. the overall structure of the machine is compact, easy to seal, high collection rate of waste gas and good environmental protection.
