Abstract
The invention discloses a surface treatment method for molds. The method comprises the following steps: degreasing treatment is performed, which is to bedew degreasing cotton with a solvent to wipe the surface of a mold and then wipe the surface of the mold with clean cotton cloth repeatedly after oil stains are removed, wherein the solvent is trichloroethylene, ethyl acetate, acetone, butanone or gasoline; the degreased mold is dipped in a following solution for 10 to 30 minutes at 60 to 65 DEG C, taken out, washed with water, aired or dried at a temperature below 80 DEG C, wherein the solution is formed by mixing sulphuric acid, potassium dichromate and water at a mass ratio of 3.6:1:8.7, or the mold is washed in a phosphoric acid solution with the mass concentration of 15 percent and then is aired; the sand-blasted or polished mold is anodized in the following solution, and voltage is raised from 0 V to 10 V within 10 minutes at 40 DEG C and kept for 20 minutes, and then is raised from 10 V to 50 V within 5 minutes and kept for 5 minutes, wherein the solution is formed by mixing chromic oxide, sulphuric acid and sodium chloride at a mass ratio of 500:1:1; and finally the mold is washed and dried at 700 DEG C. The surface treatment method has the advantages of treating mold surfaces in short period of time and improving work efficiency, along with simplicity and good washing quality.
