[0031] At present, the demolding of magnesium alloy cabin castings is mostly done manually, that is, the mold is brushed with a release agent on the mold in advance, and sand is filled in after it dries. The mold is removed after the sand hardens. For small castings, the mold is generally demolded directly with a demolding needle. For medium and large castings, it is necessary to rely on a crane. The mold is easily damaged when the mold is demolded with a demolding needle, and looseness problems will occur after a long time, affecting the demolding efficiency. When using a crane to lift and hammer the mold, it is difficult to ensure that the force point and the center of gravity of the mold are in a straight line, which can easily cause damage to the cavity, increase the workload of repairing, and the mold needs to be repeatedly hit, which damages the mold and increases labor intensity.
