Problems solved by technology

Due to the differences in various physical and chemical properties between the molding surface of the mold and the raw material to be molded, usually there will be many problems on the contact surface between the molding surface of the mold and the raw material to be molded. The surface roughness increases and the wear is serious, resulting in poor surface quality of the product and even scrapping

Abstract

The invention discloses a treatment method for improving wear resistance of a mold. The treatment method comprises the following steps of (1), surface pretreatment; (2), coating treatment; (3), quenching treatment. By means of the treatment method for improving the wear resistance of the mold, the treated mold has quite good high-temperature wear-resistant stability, the mold repairing rate of thetreated mold is obviously reduced, the service life of the treated mold is obviously prolonged, the surface performance of prepared products is better, and the treatment method for improving the wearresistance of the mold has high use and popularization values.

Description

technical field [0001] The invention belongs to the technical field of mold processing, and in particular relates to a treatment method for improving the wear resistance of a mold. Background technique [0002] At present, many parts of machinery and automobiles are produced through molds. As an important element in the field of mechanical processing, molds have increasingly become the first choice for product and parts processing due to their advantages in production and processing costs. A mold, simply put, is a tool used to shape a product or part. According to the different molded products, the molds are divided into metal molds and non-metal molds. Metal molds are generally made by casting, and then the cast metal molds are surface treated to meet their performance requirements. Due to the differences in various physical and chemical properties between the molding surface of the mold and the raw material to be molded, usually there will be many problems on the contact ...
