[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. The cast material is mostly a metal that was originally solid but heated to a liquid state (for example, copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramic. However, in the current casting process, there is a large amount of dust during sandblasting, which pollutes the working environment.

[0003] Existing Chinese patent document CN201920821633.7 is a spray device for a casting casting line, which is installed on the casting casting line to remove dust, reduce the amount of dust during sandblasting, improve the sealing of the mold during casting, ensure the quality of casting molding, and improve practicality; it includes a conveying platform, a loading trolley, a water tank, a left bracket, a right bracket, a top plate and a spray pump, and slide grooves are arranged on the left and right sides of the top of the conveying platform, and two rows of pulleys are arranged at the bottom of the loading trolley. The two rows of pulleys are respectively located in two groups of slide grooves, and three groups of left spray devices are arranged at the right end of the left bracket. The three groups of left spray devices all include two groups of left fixed pipes, two groups of left connecting shafts, left spray heads and multiple groups of left rubber strips. Three groups of right spray devices are arranged at the left end of the right bracket. The three groups of right spray devices all include two groups of right fixed pipes, two groups of right connecting shafts, right spray heads and multiple groups of right rubber strips, and also include connecting pipes and solenoid valves.

[0004] However, the above patent has certain defects when used. After long-term use, the spray head part will be blocked, resulting in unstable spray flow, which leads to poor spray effect. Utility Model Content
