Description

Technical Field

[0001] The invention relates to the technical field of casting production, and in particular to a coating device for a special-purpose casting cylinder mud core and an operating method thereof. Background Art

[0002] Casting is one of the earliest metal heat processing technologies mastered by humans. 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.

[0003] Special cylindrical cores are needed in the casting production process. Before casting the casting, the outer surface of the core needs to be painted with the corresponding coating. The coating quality of the core is the basis for ensuring the quality of the inner hole of the casting. The thickness and uniformity of the coating on the surface after casting has a direct impact on the refractoriness and surface quality of the casting after subsequent molten iron pouring.

[0004] For some castings with larger inner holes, the height of the cylindrical clay core used for casting is 3-5 meters. The paint painting work of the cylindrical clay core of this height is currently completed by manual operation. The manual painting with a long-handled brush is time-consuming and labor-intensive, and the paint painting is uneven, which requires multiple re-brushing, which not only increases the labor intensity of the operators, but also reduces the paint painting efficiency, and seriously affects the quality of the sand mold.

[0005] In addition, because the paint used to paint the outer surface of the cylinder mud core is an alcohol-based paint, it is very easy for the operator to accidentally inhale it during the manual painting process, which brings great harm to the operator and poses a major safety hazard, causing great inconvenience to the painting work of the outer surface of the cylinder mud core. Summary of the invention

[0006] The invention provides a coating device and an operating method for coating a special cylindrical mud core for casting. The coating device and the operating method have a reasonable overall design, a simple structure and are easy to operate. Through the effective combination of a spray ring structure, a driving structure and a coating conveying structure, the cylindrical mud core can be automatically sprayed, and the coating can be evenly sprayed onto the outer peripheral surface of the cylindrical mud core, which not only reduces the labor intensity of the operator, but also improves the coating efficiency. At the same time, it can also effectively prevent the operator from accidentally inhaling the coating and avoid harm to the operator, which brings great convenience to the coating work of the outer peripheral surface of the cylindrical mud core.
