The principle of V-method casting, i.e. vacuum sealing moulding, is to utilize plastic film to seal sand box, and use vacuum pump to pump out air in mould, so as to form pressure difference between inside and outside of mould, and compact dry sand to form required mould cavity. The biggest advantage of V-method casting is that no adhesive is used, thus reducing the sand treatment work, greatly reducing the labor amount for molding and cleaning the burnt sand of castings, and ensuring the recovery rate of used sand to be more than 95%.

After the existing balancing weight is shaked, cooling is needed, and after the cooling is finished, a casting is hung by a shot blasting worker after the casting passes through a workpiece loading station of a shot blasting machine, and residual sand of the casting is cleaned. Because balancing weight cooling cycle is long and the productivity is big, in order to reach refrigerated purpose, just need put the balancing weight, and this kind is put and is leaded to the balancing weight in the cooling process, has the problem that area is big, simultaneously, because area increases, leads to follow-up transportation comparatively troublesome, need adorn the balancing weight to the dolly, then go to shot-blasting machine department again and lift off the balancing weight, for this reason, has seriously restricted production efficiency.
