1.采用了新型多功能下壓式直沖射砂氣包，實(shí)現(xiàn)了高壓氣流吹均壓射砂，環(huán)形芯盒模腔可得到均實(shí)充砂，有效地保證了砂芯的結(jié)構(gòu)強(qiáng)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.采用了移動(dòng)式浮動(dòng)射頭與吹氣板，加砂位與射砂位分開(kāi)，在避免了加砂閥跑砂的同時(shí)實(shí)現(xiàn)了射頭下壓射砂及吹氣板下壓吹氣（工作臺(tái)及芯盒不動(dòng)），降低了機(jī)器運(yùn)行能耗，縮短了運(yùn)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.采用了全新的脫模出芯方式：在開(kāi)模的同時(shí)芯棒下抽，砂芯由底板直接送出。其明顯優(yōu)點(diǎn)是：砂芯受力合理，脫?？?，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.模具安裝空間及開(kāi)模行程在一定范圍內(nèi)無(wú)級(jí)可調(diào)，有效避免了大馬拉小車的現(xiàn)象，適應(yīng)了規(guī)格跨度較大的系列砂芯生產(chǎn)。大型射芯機(jī)的使用范圍擴(kuò)大到DN80-1000,降低了工程建設(shè)投資。

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.機(jī)器整體結(jié)構(gòu)緊湊，便于封閉，廢氣收集率高，環(huán)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.
