A Surface Treatment Process of Silica Sol Wax Model for Valve Castings

Abstract

The invention provides a surface treatment process of silica sol wax molds for valve castings. The operation completed by the cooperation of the base, the moving frame, the positioning bolts, the wrapping device, the ring group, the dual-purpose device, the cleaning device and the erecting ring can be solved by the invention. When wiping manually, due to the faster heat dissipation, the residue needs to be removed quickly. However, the heating temperature is high, and manual wiping is difficult to remove quickly. There may be burns during the wiping process, and holding a hair dryer is harmful to the skin. It is difficult to determine the distance between the two when the wax mold is heated, and the temperature is not enough or the temperature is too high. When it needs to be polished, because its surface is in a thermal state, it is difficult to move. It needs to wait for the wax mold to cool down and harden naturally. polishing etc.

Description

technical field [0001] The invention relates to the field of casting surface treatment, in particular to a surface treatment process for a valve casting silica sol wax mold. Background technique [0002] The appearance of the silica sol wax mold is mainly to solve the production of some products with complex structure, and the accuracy of the wax mold directly affects the accuracy of the product. After most wax molds are produced, there will be a lot of particle residues on the surface. Traditional The removal method is that people use a hair dryer to warm the part with particles, and then use a soft cloth by hand to wipe off the particle residue. [0003] 1. Due to the fast heat dissipation, the residue needs to be removed quickly. However, the heating temperature is high, and manual wiping is difficult to remove quickly. Burns may occur during the wiping process. Heating, it is difficult to determine the distance between the two, and the temperature is not enough or the t...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a surface treatment process of silica sol wax molds for valve castings, which can solve the problem of removing residues due to faster heat dissipation during manual wiping, but the thermalization temperature is higher. Manual wiping, difficult to remove quickly, may cause burns during the wiping process, and hold a hair dryer to heat the wax model, it is difficult to determine the distance between the two, prone to insufficient or high temperature, it needs to be polished When the surface is heated, it is difficult to move, and it is necessary to wait for the wax model to cool down and harden naturally before polishing.
