A metal mold casting method of rigging system configuration and brushing of coatings

The present invention relates to a metal mold casting method to take the system configuration and brushing coatings. Configuration is anhydrous zinc oxide, sodium silicate, asbestos powder dry mixed, stirred uniformly, poured into deionized water of 65 ℃ ~ 75 ℃ side down while stirring until completely until homogeneous; spraying method comprising step: to take down the coating has been configured; to preheat the blow mold is completed; rigging system for the mold coating applicator pen, a thickness of 0.3 ~ 0.5mm; thickness of the coating feeder control 1 ~ 3mm; preheating fixed, a good spraying charged metal holding furnace baking mold, the mold is preheated to the working temperature of 350 ~ 420 ℃, and held 1 ~ 2h. The method of the present invention is formulated coating and brushing method can effectively solve the metal mold Misrun production process, casting defects such as cold shut. Better protection of metal type, the size of the mold to further ensure stable quality.
