[0002] Mold steel is a type of steel used to manufacture cold stamping dies, hot forging dies, die-casting dies and other molds. The quality of mold steel depends not only on reasonable structural design and processing accuracy, but also on mold materials and heat treatment. Therefore, oil tempering treatment is required. Oil tempering treatment is to use oil as the tempering medium. Oil is used for tempering of alloy steel and small-section carbon steel, which can not only obtain satisfactory hardenability and hardenability, but also prevent cracking and reduce deformation.

[0003] At present, a Chinese patent with announcement number CN212051517U discloses an oil tempering device for mold steel, wherein a bracket is arranged outside the tempering cylinder, a top plate is arranged at the upper end of the bracket, and the top plate is located directly above the tempering cylinder, a workbench is arranged on the upper surface of the top plate, a winding roller is arranged inside the workbench, and a rotating shaft is arranged inside the winding roller. However, in the above patent, the stability of unloading the tempered mold steel by wire rope and hook is poor, and the mold steel can only rise to the top of the tempering cylinder during the removal process, which is more troublesome to remove and unload the mold steel inside the tempering box, reducing the tempering efficiency of the mold steel. Therefore, we propose an oil tempering device for mold steel to solve the above problems. Utility Model Content
