Background
The molten steel smelted by the vacuum induction furnace is usually molded, and the mold is usually an integral straight barrel mold or a half-type half mold which can be disassembled. When an integral straight barrel mold is used, the problem of difficult later demolding often exists. The reasons for the difficulty in demolding are mainly: the inner wall of the die has insufficient smoothness or uneven smoothness; molten steel is flushed in the same place of the die for a long time in the steel casting process, so that the inner wall of the die is melted and damaged to form a dent; the shrinkage ratio after cooling of the molten steel is insufficient.
At present, the traditional demolding method is to separate the steel ingot from the mold in a special demolding pond by adopting a physical impact mode. This approach tends to produce greater noise and dust, and also presents a certain safety risk. In addition, when the mold is difficult to be released, the steel ingot is sometimes taken out in a mode of damaging the mold, so that great waste is caused.

Although the demolding device can realize demolding of the steel ingot to a certain extent, the hydraulic cylinder is required to overcome the gravity of the steel ingot to do work during demolding, so that the energy consumption is high and the demolding is difficult.
