Laser cleaning method for tire moulds

Abstract

The invention discloses a laser cleaning method for tire moulds and aims to achieve safe, environment-friendly and efficient cleaning of the tire moulds. According to the technical scheme, the laser cleaning method is implemented by large difference between mould surfaces and attachments in absorption coefficient of certain wavelength laser energy. The laser energy radiating to the mould surfaces are mostly absorbed by the attachments on the mould surfaces, the attachments are evaporated or swelled instantly after being heated or vaporized and are driven to separate from the mould surfaces by vapor flow formed on the surfaces. The mould surfaces are not damaged.

Description

technical field

[0001] The invention belongs to a laser cleaning method in the technical field of tire mold cleaning. Background technique

[0002] 1. Tire vulcanization requires the use of molds, which are inevitably polluted by the comprehensive deposition of rubber, compounding agents and release agents during use (the main pollutants are sulfides, inorganic oxides, silicone oil and carbon black, etc.), Long-term use will cause mold pollution and fouling, which will affect the quality of tires. Therefore, the mold must be cleaned frequently to ensure the cleanliness of its surface, so as to ensure the quality of the tire and the life of the mold.

[0003] 2. There are the following methods for cleaning tire molds in the industry:

[0004] (1) Dry ice blasting method: liquid carbon dioxide is made into dry ice spherical particles through a dry ice preparation mechanism, and then sprayed onto the mold surface at high speed, and the purpose of removing attachments is achie...
