Problems solved by technology

[0002] At present, the quenching process of H13 steel aluminum alloy die-casting mold is relatively complicated, and there is no unified specification and standard, resulting in uneven quality of the produced steel gears. Many repeated processes also make the production efficiency low and increase the labor burden of workers. At the same time, the market competitiveness of the product is not high
For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences. At the same time, the energy consumption is serious and the production efficiency is not high.

Description

technical field [0001] The invention belongs to a heat treatment process, and belongs to a quenching process of an H13 steel aluminum alloy die-casting mold. Background technique [0002] At present, the quenching process of H13 steel aluminum alloy die-casting mold is relatively complicated, and there is no unified specification and standard, resulting in uneven quality of the produced steel gears. Many repeated processes also make the production efficiency low and increase the labor burden of workers. At the same time, the market competitiveness of the product is not high. For some operators who have just entered the industry, there is no clear method and process, which often causes mistakes and omissions during operation, and may even cause serious consequences. At the same time, the energy consumption is serious and the production efficiency is not high. Contents of the invention [0003] The object of the present invention is to provide a quenching process for an H13...
