Problems solved by technology

Due to the relatively fast stamping speed of the high-speed stamping die, there is mutual friction between the punch and the unloading insert, the processed material, and between the processed material and the knife edge, resulting in wear of various parts, which not only affects the precision of high-speed stamping, but also shortens the Increased service life of high-speed stamping dies
[0003] At present, the method of lubricating the mold with lubricating oil has strict requirements on the structure of the mold, and the mold needs to be designed with a precise oil groove, which makes the mold processing more difficult and prone to blockage

Abstract

The invention relates to a high-temperature mould lubricating particle, which is prepared from the following raw materials (by weight): 100 parts of PE, 80-100 parts of nano-calcium carbonate, 5-10 parts of an EBS dispersant, 2-4 parts of zinc stearate, 8-16 parts of propylene glycol methyl ether acetate, 0-0.5 part of a fluoride reagent, 0.1-0.2 part of tertiary pentyl peroxy ketal and 0.1-0.2 part of cuprous chloride or iron chloride. According to the application method of the lubricating particle, during die casting of moulds, the lubricating particle is injected into a mould cavity, the lubricating particle is heated in the high-temperature mould cavity to be fused, and then a lubricating film is formed on the surface of the mould. The lubricating film raises smoothness of the inner wall of the mould and is convenient for demoulding operation.

Description

technical field [0001] The invention belongs to the technical field of mold lubrication, and in particular relates to a mold lubrication particle and a preparation method thereof. Background technique [0002] Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of the processed parts are directly related to the design and preparation of stamping dies. Due to the relatively fast stamping speed of the high-speed stamping die, there is mutual friction between the punch and the unloading insert, the processed material, and between the processed material and the knife edge, resulting in wear of various parts, which not only affects the precision of high-speed stamping, but also shortens the Increased the service life of high-speed stamping dies. [0003] At present, the method of lubricating the mold with lubricating oil has strict requirements on the structu...
