Molding machine mould
1)高压造型线：利用高压(大于0.7Mh)压实造型生产线。高压造型生产率高，所得铸件尺寸精度高和表面质量较好。同时，自于砂型紧实度高，强度大，砂型受振动或冲击而塌落的危险小。
1) High pressure molding line: using high pressure (greater than 0.7Mh ）Compaction molding production line. High pressure molding has high productivity, high dimensional accuracy and good surface quality. At the same time, due to the high compactness and strength of sand mold, the risk of sand mold collapse caused by vibration or impact is small.
2)射压造型线：射压造型就是利用压缩空气将型砂以很高的速度射人砂箱而得到紧实。射压造型具有很多优点：紧实度分布均匀、工作无振动、无噪、紧实速度快、机器结构比较简单等。其又分为水平分型造型线和垂直分型造型线两种。
2） Injection molding line: injection molding is to use compressed air to inject molding sand into the sandbox at a high speed to get compact. Injection molding has many advantages: uniform compactness distribution, no vibration, no noise, fast compaction speed, simple machine structure, etc. It can be divided into horizontal parting line and vertical parting line.
3)气冲造型线：气冲造型就是利用具有一定压力的气体瞬时膨胀释放出来的冲击被作用在型砂上使其紧实，克服了粘土膜引起的阻力，提高了型砂的流动性。其砂型特点是紧实度均匀且分布台理，靠模样处的紧实度高于铸型背面。
3) Air impact molding line: air impact molding is to use the impact released by the instantaneous expansion of gas with a certain pressure to act on the molding sand to make it compact, overcome the resistance caused by clay film, and improve the fluidity of molding sand. The sand mold is characterized by uniform compactness and distributed bedding, and the compactness near the pattern is higher than that on the back of the mold.
4)静压造型线：静压造型就是在砂箱内填砂，对型砂施以压缩空气进行气流加压，用压实板在型砂上部压实，使其上下紧实度均匀。这种方法要求模板排气好，砂箱与模板密封好。其特点是铸件尺寸标准，生产率高。
4) Static pressure molding line: static pressure molding is to fill sand in the sand box, apply compressed air to the molding sand for air pressure, and use the compaction plate to compact the upper part of the molding sand to make its upper and lower compactness uniform. This method requires good exhaust of formwork and sealing of sand box and formwork. It is characterized by standard casting size and high productivity.
