Embodiment 1

[0010] 1. Quartz sand with a diameter of 0.1 μm and glass beads with a diameter of 0.3 μm are mixed according to the ratio of quartz sand: glass beads=1:1;

[0011] 2. Use a high-pressure spray gun to process the pattern area of ​​the mold to be treated. The nozzle diameter of the high-pressure spray gun is 1.0mm. When the spray gun sprays, it is 200mm away from the surface of the mold, and the horizontal movement speed is 0.02m / s.

Embodiment 2

[0013] 1. Quartz sand with a diameter of 0.2 μm and glass beads with a diameter of 0.4 μm are mixed in the ratio of quartz sand: glass beads=1:3;

[0014] 2. Use a high-pressure spray gun to treat the pattern area of ​​the mold to be treated. The nozzle diameter of the high-pressure spray gun is 1.1mm. When the spray gun sprays, it is 250mm away from the surface of the mold, and the horizontal moving speed is 0.03m / s.

Embodiment 3

[0016] 1. Quartz sand with a diameter of 0.1 μm and glass beads with a diameter of 0.4 μm are mixed according to the ratio of quartz sand: glass beads=1:5;

[0017] 2. Use a high-pressure spray gun to process the pattern area of ​​the mold to be treated. The nozzle diameter of the high-pressure spray gun is 1.2mm. When the spray gun sprays, it is 300mm away from the surface of the mold, and the horizontal movement speed is 0.04m / s.

Abstract

The invention relates to an extinction method of a slushing mold, belonging to a mold surface treatment method. The method includes the following steps: firstly, quartz sands with 0.1-0.2 Mum of diameter and glass balls with 0.3-0.4Mum of diameter are mixed in the proportion of 1:1-1:5; secondly, the figured zone of the mold is treated by a high-pressure ejection gun, the nozzle of the ejection gun has 1.0-1.2mm of diameter, the distance from the ejection gun to the surface of the mold is 200-300mm and the horizontal traveling speed of the ejection gun is 0.02-0.04m / s in the ejection process. The invention has the advantages that the extinction method is applicable not only to the surface treatment of various electroplated nickel casing in the automobile interior ornament product production field, but also to the surface treatment of nickel molds in other fields which demand for high surface gloss. The extinction method is convenient for operation, the raw materials are easily found and the cost is low.

Description

technical field [0001] The invention belongs to a surface treatment method of a mould. Background technique [0002] After the slush mold has been used for a period of time, the surface of the pattern area of ​​the mold is adhered to the surface of the mold due to wear and oil from the powder, or because of emergencies in production: such as an alarm shutdown during production, the mold and the product are heated for a long time at the same time, resulting in The surface of the mold is sintered, and the gloss of the produced skin cannot meet the requirements of the drawing. The mold can only be scrapped as a whole or shipped back to the slush mold supplier, usually in Germany or Japan, for matting treatment. In the past, because there was no matting treatment technology for slush molds in China, when the gloss of the skin was unqualified, the entire mold could only be scrapped, which was a big waste; or the mold that needed gloss adjustment was shipped back to the original s...
