Polish method of a plastic spray coating

Abstract

The invention provides a polishing method for a plastic spraying coating; a corundum abrasive paste prepared automatically is used for polish, wherein the surface roughness reaches Ra0.8; then toothpaste is used to repair and grind the polishing type cavity surface, wherein the surface roughness can reach Ra0.4. The toothpaste particles are soft, small and uniform, and thinner than the corundum abrasive paste particles, thus being capable of further improving the polishing effect. After the mold cavity surface is sprayed and coated with fluorine-46 plastic, the hardness is very low, the small particles of the corundum abrasive paste are left on the coating, finally, the toothpaste is used as a polishing medium which can polish to improve the surface roughness and also can play a role in cleaning the coating, and thereby the actual use effect is very good, and the requirement on the surface roughness of the mold is achieved.

Description

technical field [0001] The invention relates to a method for spraying and polishing a mold surface with a plastic coating, belongs to the technical field of mechanical processing technology, and relates to an ultrafine processing method for the surface of a part. Background technique [0002] In modern mechanical manufacturing engineering, in order to meet the performance and application, higher requirements are put forward for the roughness of the part surface, but it is often difficult to achieve the ideal surface due to factors such as part structure, material, processing method and process method. roughness requirements.

[0002] In modern mechanical manufacturing engineering, in order to meet the performance and application, higher requirements are put forward for the roughness of the part surface, but it is often difficult to achieve the ideal surface due to factors such as part structure, material, processing method and process method. roughness requirements

[0003] The head of the torpedo needs to be vulcanized with a layer of rubber to meet its sound transmission performance parameters. However, the contact area between the head surface and the vulcanization mold is large, and the adsorption force is very strong. In order to facilitate demoulding and improve the quality of the vulcanized surface, The roughness of the surface of the vulcanization mold must reach Ra0.4 or more

It is difficult for the surface of the steel mold to meet the roughness requirements, and it is extremely difficult to separate the steel mold from the sound-permeable rubber on the mine head

The overall plastic vulcanization mold can meet the roughness requirements, but the strength of the mold cannot meet the use requirements
