Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a casting mold processing device. Background Art

[0002] Casting mold processing refers to the mold manufacturing and processing process for the production of casting products. Casting molds are usually used to cast various parts or products made of metals, plastics and other materials. During the processing of casting molds, the molds need to be subjected to heat treatment processes including quenching and tempering to improve their hardness and wear resistance.

[0003] The existing technology has the following deficiencies: In the quenching process of the casting mold, water is one of the most commonly used quenching media with a very high cooling rate. Due to its rapid cooling characteristics, water with too low a temperature directly contacting the high-temperature mold may cause high thermal stress inside the mold, which may cause uneven temperature distribution inside and outside the mold or too fast cooling rate, resulting in cracks on the surface and inside of the mold, greatly affecting the wear resistance and service life of the mold; and in the casting process of the casting mold, after the casting metal is poured into the mold, the mold of the casting mold will continue to emit heat, and a large amount of heat energy will be lost in the process of waiting for the mold to cool down naturally; therefore, in the traditional casting mold quenching process, there is a problem that the temperature difference between the water temperature and the mold is too large, the cooling rate is too fast, which may cause cracks on the surface and inside of the mold, and the process of waiting for the mold to cool down naturally before quenching will cause a lot of heat energy waste.

[0004] Therefore, it is necessary to invent a casting mold processing equipment. Utility Model Content
