Coating system for improving coating quality of mold core

Abstract

The invention discloses a coating system for improving coating quality of a mold core. The coating system comprises stirring fans, air nozzles, a painting pond, a rack, a ventilation pipeline and an air compression device, wherein the rack is arranged at the bottom of the painting pond; the air nozzles and the stirring fans are arranged in the painting pond; the air nozzles and the stirring fans are uniformly distributed at the bottom of the painting pond; and the air nozzles are connected with the air compression device through the ventilation pipeline. According to the core coating device, the coating effect of the surface of a casting can be greatly improved, the surface of the casting is more uniform and flatter, and defects are obviously decreased; and besides, the air compression device with high power, strong power and high air compression efficiency is adopted, coating efficiency is higher, and production cost is reduced.

Description

technical field [0001] The invention relates to a coating device, in particular to a coating system for improving the coating quality of mold cores. Background technique [0002] In the foundry industry, it is often necessary to spray anti-stick coatings or thermal insulation protective coatings on casting molds. At present, manual spraying is mainly used. However, due to the complexity of many sand molds and many spray coatings, there are many uncertain factors in manual spraying. The thickness of the coating is uneven and the phenomenon of incomplete coverage often occurs. After casting, it is easy to scrap or have defects in the casting, and the subsequent processing will increase the labor cost again. The existing mechanical spraying device moves back and forth along the moving track, and the flexibility of operation Low, poor positioning accuracy, the position of the nozzle can only move left and right, and it is only used for a certain device. The position of the part ...

The existing mechanical spraying device moves back and forth along the moving track, and the flexibility of operation Low, poor positioning accuracy, the position of the nozzle can only move left and right, and it is only used for a certain device. The position of the part to be sprayed is fixed, and it is easy to cause a dead angle of spraying, and a separate uniform coating device is required, which greatly increases the extra cost
