1) 工作原理 以磨液泵和壓縮空氣為動力，通過噴槍將磨液高速噴射到模具表面，達到光飾鑄造模具的目的。磨液是用對模具有保護作用的載液與一定粒度的磨料(白剛玉砂，玻璃丸等人造磨料)按一定配比混合而成，放置在機體下部的貯箱中。工作時磨液泵將貯箱中的磨液以一定壓力和流量通過磨液管路輸入噴槍。此時，還有一磨液旁路經(jīng)裝置在其中的攪拌噴嘴高速噴出，從而使貯箱中的磨料和載液攪拌均勻；另外壓縮空氣由外接氣源經(jīng)過(溢)減壓閥、電磁閥進入噴槍。噴槍是直接執(zhí)行液體噴吵工作的主要部件。它與磨液、壓縮空氣管路系統(tǒng)相連接，設(shè)置在機體上部密閉的工作艙內(nèi)。噴射出的磨液對鑄造模具表面沖擊磨削后，從圓盤工作臺流下，經(jīng)網(wǎng)孔板返回貯箱，如此循環(huán)便完成了對鑄造模具的噴射清洗。

1) the working principle is that the grinding fluid pump and compressed air are used as the driving force, and the grinding fluid is sprayed to the surface of the mould at high speed through the spray gun to achieve the purpose of finishing the casting mould. The grinding fluid is made of a certain proportioning of a certain grinder (white corundum sand, glass pellets and other artificial abrasives) which has a protective effect on the mold, and is placed in the tank of the lower part of the body. When working, the grinding fluid pumps the grinding fluid in the tank with a certain pressure and flow through the grinding fluid line to enter the spray gun. At this time, there is a grinding liquid bypass through the device in which the stirring nozzle is spewed out at high speed, so that the abrasive and the liquid in the tank are stirred evenly, and the compressed air is passed through the external air source through the pressure relief valve and the solenoid valve into the spray gun. Spray gun is the main component of direct liquid spraying. It is connected with the grinding fluid and compressed air pipeline system, and is arranged in the closed working cabin of the upper part of the body. After the injection of the grinding fluid to the casting mold surface impact grinding, from the disc worktable flow, through the mesh plate back to the tank, so the cycle completed the spray cleaning of the casting mold.

2) 清洗工藝 根據(jù)芯盒不同的工藝要求，有兩種工作方式可供選擇：①不加壓縮空氣，只靠磨液泵供給磨液，通過噴嘴加速射向被清洗鑄造模具。適用于定期對芯盒進行一般性清洗保養(yǎng)。②磨液系統(tǒng)和壓縮空氣系統(tǒng)同時啟動，向噴槍同時提供磨液和壓縮空氣，使其在噴槍內(nèi)混合后，經(jīng)噴嘴向鑄造模具表面高速噴射氣、磨液流。由于有氣、泵兼施的工作方式，使得噴出的氣、磨液流具有更大壓力，被載液包裹著的磨液質(zhì)點動能加大，有效提高了芯盒的清洗能力(主要適用于芯盒表面樹脂結(jié)垢的清洗)。

2) according to the different technological requirements of the core box, the cleaning process can be selected as two kinds of working methods: (1) without compressed air, only the grinding liquid is supplied by the grinding pump, and the nozzle is accelerated to the washed casting mold through the nozzle. It is suitable for regular cleaning and maintenance of core boxes. At the same time, the grinding fluid system and the compressed air system start at the same time, providing the abrasive and compressed air to the spray gun at the same time, making it mixed in the spray gun and spraying gas and grinding fluid through the nozzle to the mold surface at high speed. Because of the working mode of gas and pump, the air and the grinding fluid have greater pressure, and the kinetic energy of the grinding fluid is increased, and the cleaning ability of the core box is improved (mainly for the cleaning of the resin fouling on the surface of the core box).

3) 生產(chǎn)效率和經(jīng)濟效益比較 ①使用液體噴砂機和玻璃丸清洗芯盒的工藝基本上能夠?qū)⑿竞斜砻孑^厚的樹脂結(jié)垢清理干凈，但對于較長時間沒有清洗積垢很厚的溝槽處，卻難于清除干凈。

3) comparison of production efficiency and economic benefit (1) the process of using liquid sanding machine and glass pellet cleaning box can basically clean up the thicker resin in the core box, but it is difficult to clean up the groove where the scale is not very thick for a long time.
