Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a coating process of silica sol paint on the surface of the valve casting wax pattern, which can solve the problem that when the surface of the wax pattern is dipped in refractory materials, the entire wax pattern is usually immersed in the coating solution. However, this The method often encounters some problems. Because it is the overall immersion

Abstract

The invention provides a valve casting wax mold surface silicon sol coating application process. The valve casting wax mold surface silicon sol coating application process is finished through cooperation of a waste material frame, two clamping devices, an installing frame, a material storing frame, two connecting plates, a spraying ring, two connecting rods and two application devices. By means ofthe process, the problems that when the surface of a wax mold is dipped with a refractory material, the whole wax mold is usually immersed into coating liquid, however, several problems are usually caused in this manner, as the whole immersing mode is adopted, the whole coating condition is difficult to see in the immersing process, the thicknesses of all parts of a coating layer on the surface of the wax mold which is taken out are different in most cases, the immersed coating liquid is probably mixed with impurities after being repeatedly used, and consequently the surface of a dried coating is mixed with the impurities can be solved.

Description

technical field [0001] The invention relates to the technical field of surface treatment of casting wax molds, in particular to a process for coating the surface of valve casting wax molds with silica sol paint. Background technique [0002] Valves need to use casting wax molds in the production and casting process. The specific casting method is: first make a model of the casting to be made with wax material, dip the refractory paint (a mixture of silica sol and fine sand) on the surface of the module, and then Sprinkle refractory sand, and after it is dry and solidified, heat the mold group to release the wax material from the gate to form an empty shell, and then roast the empty shell to form a strong mold shell. [0003] When dipping the refractory material on the surface of the wax model, the entire wax model is usually immersed in the coating liquid, but this method often encounters some problems, because it is the overall immersion method, it is difficult to see the o...
