Problems solved by technology

Mechanical cleaning and sandblasting cleaning are time-consuming and laborious, and may cause damage to the mold surface; ultrasonic cleaning and chemical cleaning need to put the mold completely into water or solvent, and use ultrasonic vibration or chemical erosion to remove dirt, which is cumbersome to operate and relatively expensive. High; the use of dry ice cleaning requires spraying dry ice on the mold, using the characteristics of metal and rubber inconsistency in thermal expansion and contraction, so that the dirt will fall off, the cleaning cost is high, the operation is inconvenient, and it is time-consuming
Existing technology does not have the solution to this

Abstract

The invention discloses a compound cleaning method of a rubber product mould. The method comprises the steps that S1, region analysis is conducted, wherein before cleaning, dirt accumulation conditions of the mould before and after utilization are compared, and region division is conducted on the mould according to the compared conditions; S2, a sodium bicarbonate or potassium bicarbonate solution with the mass fraction being 10-20% is sprayed on the surface of the mould until the surface of the mould is saturated, then 3-25% alums are evenly sprayed on the surface of the mould, and the mould is subjected to standing for 3-10 minutes; S3, laser cleaning is conducted; S4, after laser cleaning, water is sprayed on the surface of the mould to conduct cleaning. The method has the advantages of high rubber product mould cleaning speed, low consumed preparation amount, little water pollution and low operation cost.

Description

Technical field: [0001] The invention relates to a composite cleaning method for rubber product molds. Background technique: [0002] The base material of the rubber mold is generally made of metal materials such as aluminum and steel. After the rubber mold is used for a period of time, the rubber particles will be attached to the surface of the mold, resulting in rough surface of the obtained rubber product, which affects the quality of the product and is not easy to take out from the mold. Therefore, the mold must be cleaned after a period of use. Existing cleaning methods include mechanical cleaning, sandblasting cleaning, chemical cleaning, ultrasonic cleaning and dry ice cleaning. Mechanical cleaning and sandblasting cleaning are time-consuming and laborious, and may cause damage to the mold surface; ultrasonic cleaning and chemical cleaning need to put the mold completely into water or solvent, and use ultrasonic vibration or chemical erosion to remove dirt, which is ...
