射芯機的構(gòu)造:

The structure of the core ejection machine:

1.射芯機采用了新型多功能下壓式直沖射砂氣包，實現(xiàn)了高壓氣流吹均壓射砂，環(huán)形芯盒模腔可得到均實充砂，有效地保證了砂芯的結(jié)構(gòu)強度。

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.采用了移動式浮動射頭與吹氣板，加砂位與射砂位分開，在避免了加砂閥跑砂的同時實現(xiàn)了射頭下壓射砂及吹氣板下壓吹氣（工作臺及芯盒不動），降低了機器運行能耗，縮短了運行周期。

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：在開模的同時芯棒下抽，砂芯由底板直接送出。其明顯優(yōu)點是：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.模具安裝空間及開模行程在一定范圍內(nèi)無級可調(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)。大型射芯機的使用范圍擴大到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.

6.射芯機配置了高效連續(xù)氣化氣體發(fā)生器，及全自動高效連續(xù)混砂機磨陶瓷貼片、滿足用戶特殊需求的技術(shù)條件。耐磨陶瓷貼片的耐磨性是錳鋼280倍，是高鉻鑄鐵的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.

射芯機適用于采用樹脂砂批量生產(chǎn)各種形狀復(fù)雜、尺寸精確的砂芯；安裝了抽模和夾緊機構(gòu)，滿足五開模要求。

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.

射芯機的射砂裝置、吹胺頭能同步前后移動，定位準確、移動平穩(wěn)、靈活，操作簡單、方便。同時實現(xiàn)自動加砂，砂門開合時基本無砂泄漏、開合靈活。

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.

射芯機除射砂外、其余動作均采用液壓驅(qū)動。不僅提供了足夠的頂模力，保證射砂時不會產(chǎn)生工作臺下沉等現(xiàn)象；同時開模、合模、工作臺或射筒的移動、起芯等動作定位準確、運行平穩(wěn)可靠；而且起芯動作更平穩(wěn)有力，保證砂芯不易散列。

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.

綜上就射芯機而言具有砂芯好、尺寸精確，生產(chǎn)率高，工作可靠，勞動強度低、清潔、安全等優(yōu)點。

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、射芯機使用時要認真觀察運轉(zhuǎn)情況，在操作中應(yīng)經(jīng)常用空氣吹凈潤滑部位和運轉(zhuǎn)部位的砂粒，嚴禁各潤滑部位粘砂。

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、射芯機使用時，開閉手柄氣閥時動作要平穩(wěn)。

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

3、嚴禁開空車，必須在有載荷的情況下進行試車，檢查各工作狀態(tài)是否正常，對應(yīng)該加油的地方進行加油潤滑。試車正常后方可進行工作。

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、射芯機使用完畢后，要將手柄回到零（空）位，關(guān)閉各閥門，清掃設(shè)備，打掃現(xiàn)場，要保持設(shè)備各滑動（轉(zhuǎn)動）部位的清潔和潤滑，認真收檢工具，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、射芯機使用時，開動設(shè)備前，應(yīng)先檢查造型機的潤滑裝置是否完善，并按規(guī)定加油，檢查各緊部件是否緊固，各操作手柄是否處于零位（空位），氣閥動作是否靈活，管路有無漏氣，然后打開總氣閥放掉管路中的積氣和積水。

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. .
