Improved spray gun for die casting

Abstract

The invention discloses an improved spray gun for die casting, which is characterized in that one end of a spray steel pipe is fixedly connected with a transfer box body, one end of the middle part of the transfer box body is fixedly provided with a conveying pump, and the interior of the transfer box body is provided with a purification anti-blocking mechanism. The interception plate performs coarse filtration on the release agent to intercept solid substances mixed in the release agent, and the purification plate continues to perform fine filtration on the release agent, so that impurities are not doped in the release agent, blockage of a spraying steel pipe caused by continuous accumulation of the impurities is prevented, the spraying process can be normally performed, and reduction of the spraying amount is avoided; the inclined impact plate is arranged between the interception plate and the purification plate, the mold release agent directly impacts the inclined impact plate when passing through the interception plate after being intercepted and filtered, and the impurities still doped in the mold release agent can generate downward force during impact, so that the forward flowing force of the impurities is attenuated, and meanwhile, the impurities sink downwards under the action of the gravity of the impurities.

Description

technical field [0001] The invention relates to the technical field of die-casting spray, in particular to an improved spray gun for die-casting. Background technique [0002] Die casting is a metal casting process characterized by applying high pressure to the molten metal using the cavity of the mold. The mold is usually machined from a stronger alloy. This process is somewhat similar to injection molding. Most die-casting castings are not Iron-containing, such as zinc, copper, aluminum, magnesium, lead, tin and lead-tin alloys and their alloys, depending on the type of die-casting, need to use a cold chamber die-casting machine or a hot chamber die-casting machine, and the die-casting spray machine is used The manipulator moves the spray gun to one side of the mold, sprays out the release agent, and sprays the release agent evenly on the surface of the mold, which also plays a role in surface cleaning and rapid cooling of the mold, keeping the surface of the mold clean an...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an improved spray gun for die-casting, which can effectively solve the problem that the release agent proposed in the above-mentioned background technology is directly delivered to the inside of the spray gun. Impurities are easily mixed into the interior during production, storage and transportation. Impurities are directly injected into the spray gun and accumulate for a long time, which will easily cause pipelines and spray holes to be blocked, resulting in the problem that the subsequent spraying process will be affected.
