Automatic de-molding agent spraying system

Abstract

The invention relates to an automatic de-molding agent spraying system. The automatic de-molding agent spraying system comprises an agitation tank, a compressed air source and a spraying gun, wherein the agitation tank is communicated with the spraying gun through a de-molding agent conveying pipeline; the compressed air source is communicated with the spraying gun through a compressed air conveying pipeline; the de-molding agent conveying pipeline between the agitating tank and the spraying gun is sequentially provided with a tank body valve, a high-pressure pneumatic plunger pump and an oil amount adjusting valve; the compressed air conveying pipeline between the compressed air source and the spraying gun is sequentially provided with a decompression valve and an air quantity adjusting valve; a de-molding agent conveying pipeline between the high-pressure pneumatic plunger pump and a de-molding agent flow adjusting valve is provided with an energy accumulator; and a de-molding agent conveying pipeline between the energy accumulator and the de-molding agent flow adjusting valve is provided with a pressure sensor. According to the automatic de-molding agent spraying system disclosed by the invention, oriented and quantitative atomization and spraying on the surface of a mould can be realized so that a uniform sprayed film is formed on the surface of the mould and the surface of the mould is prevented from being damaged by being stuck with hot metal in a forging process.

Description

technical field [0001] The invention belongs to the field of forging mold release, in particular to an automatic mold release agent spraying system. Background technique [0002] The function of the release agent is to form a protective film between the mold and the hot forging blank, to avoid direct contact between the hot metal and the mold during the forging process, thereby avoiding the melting and bonding of the forging metal and the mold, causing the mold Reusability is reduced, which increases production costs. [0003] In the selection of release agent, because flake graphite itself has a layered structure, graphite has a relatively high ignition point (above 700°C), and its thermal conductivity is very good. In addition, graphite itself is incompressible. A graphite layer with a suitable particle size can isolate the hot metal from the mold, and the heat can be transmitted laterally without adhesion, so that the mold can be used repeatedly, thereby reducing product...

Problems solved by technology

[0004] In the hot forging production process, it is usually necessary to apply a graphite release agent (spraying agent) on the surface of the mold. The usual spraying method is to add the graphite release agent to the mold surface by hand, but the surface of the mold is coated The amount is difficult to control, resulting in uneven application of graphite release agent, which often causes adhesion between the forged part and the mold or the shape is inconsistent with the designed shape
