Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Before use, ensure the ventilation of the place and maintain the flow of air. Through the drainage and vent holes in the mold, the water channel and the micropores in the mold are injected with 0.45-0.55MPa air pressure for 1-8 hours. With the injection of gas, the mold The moisture in the mold gradually decreases, and when the moisture in the mold is drained, stop the gas injection. Then brush the sodium hypochlorite solution evenly on the surface of the mold with a brush, and let it stand for 30 to 45 minutes to allow the hypochlorous acid in the sodium hypochlorite sol...

Abstract

The invention discloses a high pressure pouring mold surface oxidization treatment method which comprises the steps of air injection drainage, brushing of a sodium hypochlorite solution, water injection cleaning and the like. According to air injection drainage, air with the air pressure being 0.45-0.55 MPa is injected into water channels and micro-holes in a mold through drainage and air exhaust holes in the mold till moisture in the mold is fully drained. According to brushing of the sodium hypochlorite solution, the sodium hypochlorite solution is brushed on the surface of the mold through a hairbrush. According to water injection cleaning, water with the hydraulic pressure being 0.2-0.4 MPa is injected into the water channels in the mold through water drainage holes in the mold, and the surface of the mold is washed through clean water at the same time. The high pressure pouring mold surface oxidization treatment method is easy to operate and low in cost, mold oxidization and blocking of the micro-holes in the mold are prevented while mold oxidization is eliminated, the appearance of the mold is improved, the service life of the mold is prolonged, and the oxidization treatment method can be reused and applied and popularized to ceramic mold oxidization treatment.

Description

technical field [0001] The invention relates to the field of mold maintenance, in particular to a method for blackening the surface of a high-pressure casting mold. Background technique [0002] After the high-pressure casting mold is used on the molding line for a long time, a large amount of minerals and metal impurities in the water and mud will precipitate in the micropores of the mold, causing problems such as clogging of the micropores of the mold and poor local drainage. In addition, the molding environment is humid and hot, and microorganisms are easy to breed on the surface and inside of the mold, resulting in blackening of the mold surface, and the long-term blackening state also leads to micropore blockage and poor drainage. After the mold is off the assembly line, the mold is closed and stored in the warehouse after maintenance with drugs. During the period when the molds are in the warehouse, most of the molds will still have surface blackening and poor drainag...
