射芯机的构造:

The structure of the core ejection machine:

1.射芯机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。

The 1. core machine adopts a new type of multi-function down pressure direct shooting sand gas package, which realizes the high-pressure airflow blowing sand, and the ring core box cavity can be filled with sand, effectively ensuring the structure strength of the 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.

6.射芯机配置了高效连续气化气体发生器，及全自动高效连续混砂机磨陶瓷贴片、满足用户特殊需求的技术条件。耐磨陶瓷贴片的耐磨性是锰钢280倍，是高铬铸铁的180.5倍。

6. The core-shooting machine is equipped with high-efficiency continuous gasification gas generator, and automatic high-efficiency continuous sand mixer to grind ceramic patches to meet the special requirements of users. The wear resistance of wear resistant ceramic patch is 280 times of manganese steel and 180.5 times higher than that of high chromium cast iron.

射芯机适用于采用树脂砂批量生产各种形状复杂、尺寸精确的砂芯；安装了抽模和夹紧机构，满足五开模要求。

The core-shooting machine is suitable for mass production of sand cores with complex shapes and precise sizes by using resin sand, and a drawing and clamping mechanism is installed to meet the requirements of Five-opening mould.

射芯机的射砂装置、吹胺头能同步前后移动，定位准确、移动平稳、灵活，操作简单、方便。同时实现自动加砂，砂门开合时基本无砂泄漏、开合灵活。

The sand shooting device and the amine blowing head of the core shooter can move forward and backward synchronously. The positioning is accurate, the movement is stable and flexible, and the operation is simple and convenient. At the same time, automatic sand adding is realized, sand door opening and closing basically no sand leakage, opening and closing flexible.

射芯机除射砂外、其余动作均采用液压驱动。不仅提供了足够的顶模力，保证射砂时不会产生工作台下沉等现象；同时开模、合模、工作台或射筒的移动、起芯等动作定位准确、运行平稳可靠；而且起芯动作更平稳有力，保证砂芯不易散列。

In addition to shooting sand, the core ejection machine adopts hydraulic drive. Not only does it provide enough die force to ensure that the work table will not sink in the sand shooting, and the movement of the die, the working table or the barrel, the movement of the core, the movement of the core and so on is accurate and stable and reliable, and the movement of the core is more stable and powerful, and the sand core is not easy to hash.

综上就射芯机而言具有砂芯好、尺寸精确，生产率高，工作可靠，劳动强度低、清洁、安全等优点。

In a word, the core shooter has the advantages of good core, accurate size, high productivity, reliable work, low labor intensity, cleanliness, safety and so on.

1、射芯机使用时要认真观察运转情况，在操作中应经常用空气吹净润滑部位和运转部位的砂粒，严禁各润滑部位粘砂。

1, when the core machine is used, the operation should be carefully observed. In the operation, the sand particles of the lubricating parts and running parts should be purge with the air, and the sand is strictly forbidden in all the parts of the lubrication.

2、射芯机使用时，开闭手柄气阀时动作要平稳。

2. When the core machine is used, the movement of the valve must be steady when opening and closing the handle.

3、严禁开空车，必须在有载荷的情况下进行试车，检查各工作状态是否正常，对应该加油的地方进行加油润滑。试车正常后方可进行工作。

3. It is strictly forbidden to drive an empty car. It must be tested under the condition of load to check whether the working state is normal or not and to lubricate the place where the oil should be refueled. The test car can work in the normal rear.

4、射芯机使用完毕后，要将手柄回到零（空）位，关闭各阀门，清扫设备，打扫现场，要保持设备各滑动（转动）部位的清洁和润滑，认真收检工具，模具。

4, after the core machine is used, it is necessary to return the handle to the zero (empty) position, close the valves, clean the equipment, clean the scene, keep the cleaning and lubrication of the sliding (rotating) parts of the equipment, and carefully collect and check the tools and moulds.

5、射芯机使用时，开动设备前，应先检查造型机的润滑装置是否完善，并按规定加油，检查各紧部件是否紧固，各操作手柄是否处于零位（空位），气阀动作是否灵活，管路有无漏气，然后打开总气阀放掉管路中的积气和积水。

5, when the machine is used, it is necessary to check whether the lubricating device of the molding machine is perfect before the equipment is opened, and to check whether the tight parts are fastened, whether the handle handles are in the zero position (vacancy), the valve movement is flexible, the pipe has no air leakage, and then the gas and water in the pipeline are opened. .
