Problems solved by technology

[0005] (1) The flow adjustment is not uniform, resulting in inconsistent spraying thickness on the mold surface;
[0006] (2) The flow channel is easy to block and difficult to clean;
[0007] (3) The atomization is uneven and easy to form drops;
[0009] (5) The response delay of the flow control mechanism is high, and the opening and closing are not timely;
[0010] (6), spraying and air blowing are carried out by two independent components, the cost is higher and the equipment is more complicated

Abstract

The invention discloses a mold spraying frame which comprises a spraying seat. The spraying seat is connected with a cantilever. One end of the cantilever is connected with the spraying seat, and a connecting disc is arranged at the other end of the cantilever and is provided with a screw hole. The spraying seat is provided with at least one spraying vertical face. A transverse nozzle set and a vertical nozzle set are arranged on each spraying vertical face. Each transverse nozzle set is formed by multiple transversely-distributed nozzles. Each vertical nozzle set is formed by multiple vertically-distributed nozzles. The mold spraying frame can carry out coating spraying on a mold stably and can be started and stopped fast, coating waste can be avoided, the environment can be protected, the spraying angle and direction can be adjusted, and the pressure casting spraying time can be effectively shortened; and the nozzles facilitate the work of coating flow adjusting and clearing, and thespraying efficiency can be effectively guaranteed.

Description

technical field [0001] The invention relates to spraying equipment, in particular to a mold spraying rack. Background technique [0002] The die-casting process uses high pressure to hydraulically inject metal into the mold cavity, and the molten metal is cooled and solidified under pressure to form a casting. The die-casting process can manufacture metal parts with complex shapes, clear outlines, thin walls and deep cavities, and the utilization rate of materials is high. Spraying is an important link in the die-casting process. It can effectively prevent the die-casting from welding with the die-casting mold, reduce the frictional resistance when the die-casting is ejected, prevent the mold from sticking, and play a cooling role; after spraying, the mold needs to be blown dry. [0003] Since the latent heat of crystallization of magnesium alloy is smaller than that of aluminum alloy, the solidification time is faster, and it is more sensitive to the mold temperature. If ...
