A kind of equipment for spraying casting coating on the surface of molding sand for sand casting

Abstract

The invention relates to equipment for spraying casting coating to the surface of molding sand for sand mould casting. The equipment comprises a bottom plate, a tumbling device and a coating device, ahole is formed in the middle portion of the front end of the bottom plate, the tumbling device is mounted on the upper end surface of the middle portion of the bottom plate, and the coating device isinstalled on the inner side face of the upper end of the tumbling device. The invention can solve the problems that an existing spraying machine cannot prevent flow marks and accumulation of coating,a nozzle cannot be rotated and tilted, the coating cannot cover the surface of a sand mould from all directions, and the spraying angle cannot be adjusted at will; and the function of automatically spraying the casting coating to the surface of the molding sand can be realized.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to equipment for spraying casting paint on the sand surface for sand casting. Background technique [0002] Sand casting is the most popular and simplest type of casting and has been used for centuries. Sand casting is used to manufacture large parts such as gray cast iron, ductile iron, stainless steel and other types of steel. The main steps Including painting, moulding, core making, molding, melting and pouring, cleaning etc. [0003] In sand casting, after the pouring process is completed, in order to make the casting easy to separate from the molding sand, a layer of resin sand must be sprayed in the sand mold before pouring. At present, spraying casting coating is the main means to obtain good surface quality of castings. The existing The spraying method cannot overcome the flow marks and accumulation of the paint, and manual inspection and removal are required, which gr...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a device for spraying casting paint on the surface of the sand for sand casting, which can solve the problem that the existing spraying machine cannot prevent the flow marks and accumulation of the paint, the nozzle cannot be rotated and tilted, and the paint cannot cover the sand mold in all directions. The surface and the angle of spraying cannot be adjusted at will; it can realize the function of automatically spraying casting paint on the surface of the molding sand, which can prevent the flow marks and accumulation of the paint, the nozzle can be rotated and tilted, and the paint can cover the surface of the sand mold in all directions. The spraying angle can be adjusted at will, etc.
