Anti-sticking spraying device for moulding sand box

Abstract

The invention discloses an anti-sticking spraying device for a moulding sand box. The anti-sticking spraying device comprises a spraying gun, a spraying gun mixing control device, an electromagnetic valve control device, a spraying material stirring barrel and a compressed air bag, wherein the compressed air bag is connected with the air inlet end of the electromagnetic valve control device, and the air outlet end of the electromagnetic valve control device is connected with the air inlet end of the spraying gun mixing control device; the feeding end of the spraying gun mixing control device is connected with the spraying material stirring barrel, and a discharging port of the spraying gun mixing control device is connected with the spraying gun. By performing spraying on the surface of the sand box, the problem that iron sticks to the surface of the sand box can be effectively solved; every time when a sand mould track surface passes through spraying materials before pouring, if molten iron splashes in the pouring process, the molten iron can slip off along the sand mould track surface without sticking to the surface of the sand box.

Description

technical field [0001] The invention relates to the field of casting, in particular to an anti-sticking spraying device for a molding flask which is eroded by molten iron splashes during the pouring process. Background technique [0002] The sand mold of the molding line is pushed to the pouring line after the box is closed, and the pouring ladle often has molten iron splashed or sprinkled on the surface of the sand box during pouring. In severe cases, the molten iron will stick to the track surface of the sandbox, causing the sand mold to be stuck on the track after being demolded. In the prior art, most foundries will encounter the problem of pouring molten iron on the sand mold. The conventional avoidance measure is to install hanging plates and brushes on the cooling line after pouring, which will cause long-term wear of the sand box and cause sand The size of the box changes, affecting the accuracy of the equipment.
