覆膜砂射芯机清洗工艺

发布时间:2020-01-11
覆膜砂射芯机清洗工艺Cleaning process of film coated sand ejection machine根据芯盒不同的工艺要求,有两种工作方式可供选择:According to the different process requirements of the core box, there are two modes of work to be selected:①不加压缩空气,只靠磨液泵供给磨液,通过喷嘴加速射向被清洗铸造模具。适用于定期对芯盒进行一般性清洗保养。(1) without compressed air, the grinding fluid is supplied only by a grinding pump, which is accelerated through the nozzle to the washed mold. It is suitable for regular cleaning and maintenance of the core box.②磨液系统和压缩空气系统同时启动,向喷枪同时提供磨液和压缩空气,使其在喷枪内混合后,经喷嘴向铸造模具表面高速喷射气、磨液流。由于有气、泵兼施的工作方式,使得喷出的气、磨液流具有更大压力,被载液包裹着的磨液质点动能加大,有效提高了芯盒的清洗能力(主要适用于芯盒表面树脂结垢的清洗)。(2) the grinding system and the compressed air system start simultaneously, provide liquid and compressed air to the spray gun at the same time, make it mixed in the spray gun, and spray the gas and liquid flow to the surface of the casting mould through the nozzle. Due to a gas pump, and way of working, the ejective gas, grinding fluid flow with greater pressure, by loading the grinding liquid particle kinetic energy liquid wrapped with the increase, improve the cleaning ability of core box (mainly suitable for cleaning the surface of core box resin fouling).
