Problems solved by technology

For the inner side of complex mold core-pulling, traditional spraying methods (manual spraying or automatic spraying) cannot be used to spray in place. Since the product is not covered with release agent, this part is prone to burns, aluminum sticking, buckling, cracking, etc. Die-casting defects affect production efficiency, production quality and production continuity

Abstract

The invention discloses a spray coating device in a mold. The spray coating device comprises a gas-liquid mixing system and a control circuit, wherein the gas-liquid mixing system comprises an integrated block (1), a throttling orifice, a knurling piece (2), a switch shaft (3), a nut (9) and a sealing element; the throttling orifice is used for controlling the flow rate of demolding agent mixed liquid; a plurality of gas-liquid mixing body outlets are formed in the top of the integrated block (1), and communicate with a pipeline which in oriented arrangement with spray coating dead corners in the mold; an gas-circuit electromagnetic valve (10) is arranged on a gas source pipeline; a liquid-circuit electromagnetic valve (11) is arranged on a liquid source pipeline; and the gas-circuit electromagnetic valve (10) and the liquid-circuit electromagnetic valve (11) are connected with the control circuit through conducting wires. Through the adoption of the spray coating device disclosed by the invention, oriented spray coating on the spray coating dead corners can be realized, and appearance problems of a product, such as burn injury, mold sticking, tension injury, and pull cracks, which are caused by failed spray coating of local positions of the mold, are avoided, so that the quality of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of casting, and more specifically relates to a spraying device in a mold. Background technique [0002] Die casting production is a dynamic thermodynamic process, in which the cavity surface is scoured by liquid metal at high pressure, high speed, and high temperature, and the cavity surface has a strong tendency to adhere. Spraying the release agent is just to form a thin film on the surface of the cavity to isolate the liquid metal, so the reasonable spraying of the release agent is an important factor to ensure the quality of the casting, the life of the die casting, and the production efficiency. The role of the release agent mainly has the following aspects: [0003] (1) Make the filling of liquid metal smooth, which is conducive to forming, prevent sticking and welding, and make the casting obtain bright, smooth and flat surface quality. [0004] (2) Protect the mold, avoid the erosion of the surface...
