[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping molds, hot forging molds and die-casting molds. Molds are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors and electrical appliances. The quality of the mold directly affects the quality of the pressure processing technology, the precision output of the product and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to reasonable structural design and processing accuracy.

[0003] During the production and processing of mold steel, a heat treatment device is usually required to heat the mold steel to ensure the quality of mold steel production. For example, a rotary heat treatment device for mold steel surface proposed in Chinese patent CN 217922200 U has a mold steel located in a placement frame. The output shaft of a motor drives a half gear to rotate, and the half gear meshes with two racks in turn during the rotation process, so that the frame reciprocates in the placement groove, and the liquid on the surface of the mold steel in the placement frame is forced to move, so that the water in the cooling device of the mold steel heat treatment process is in a moving state during actual use, resulting in the water temperature at the mold steel being increased and then flowing, and the water temperature change in other places in the placement groove is accelerated, so that the cooling speed of the mold steel is accelerated. However, this design has the disadvantage of being inconvenient to remove the material, resulting in the mold steel being unable to be quickly removed from the inner side of the heat treatment device after the mold steel is heat-treated, and then the next mold steel cannot be quickly heat-treated, which affects the speed of mold steel processing, is inconvenient to use, cannot meet the actual use needs, and reduces the use efficiency and use effect of the heat treatment device.

[0036] The working principle of the above embodiment is:

[0037] (1) The mold steel that needs heat treatment is sealed and placed inside the heating box 12. The mold steel can be heated by two heating plates 13, thereby achieving the purpose of heat treatment of the mold steel. The heating effect of the mold steel can be enhanced by the hot air blower 15 and the air inlet pipe, thereby improving the effect of heat treatment of the mold steel.

[0038] (2) After the mold steel is heat treated, the sealing cover 14 is opened first, and then the hydraulic oil can be pumped into the inner side of the hydraulic rod 4 through the hydraulic pump 3, so that the hydraulic rod 4 can be driven, thereby driving the drive box 5, the motor 6, the threaded rod 7, the threaded block 8, the movable rod 9 and the movable plate 10 to move left and right in turn, and the movable plate 10 can be moved to the top of the heating box 12, and then the threaded rod 7 can be driven by the motor 6 to rotate. Because the threaded rod 7 is threadedly connected to the threaded block 8, the threaded rod 7 will drive the threaded block 8, the movable rod 9 and the movable plate 10 to move downward in turn during the rotation of the threaded rod 7, and the movable plate 10 can be moved to the inner side of the heating box 12 so that the movable plate 10 fits the mold steel.

[0039] (3) Then, the two electric push rods 17 can respectively drive the two movable clamping blocks 18 to move relative to each other. During the relative movement, the two movable clamping blocks 18 will fit with the mold steel body 11, so that the mold steel body 11 can be clamped and fixed to prevent the mold steel body 11 from falling during the stripping process, thereby ensuring the stripping effect of the mold steel body 11.

[0040] (4) Then, the threaded rod 7 can be driven to rotate by the motor 6. Since the threaded rod 7 is threadedly connected to the threaded block 8, the threaded rod 7 will drive the threaded block 8, the movable rod 9, the movable plate 10 and the mold steel body 11 to move upward in turn during the rotation of the threaded rod 7. The mold steel body 11 can be moved out from the inner side of the heating box 12, thereby achieving the purpose of removing the mold steel body 11.

[0041] (5) After the mold steel body 11 is stripped, through the above principle, the mold steel body 11 can be moved to the top of the support table 23 through the drive of the hydraulic pump 3, the hydraulic rod 4, the motor 6, the threaded rod 7, the threaded block 8, the two electric push rods 17 and the two movable clamps 18, so as to facilitate the subsequent cooling of the mold steel body 11.

[0042] Compared with the prior art, the overall structure is simple and easy to use, and the purpose of facilitating material removal from the heat treatment device is achieved. After the mold steel is heat-treated, the mold steel can be quickly taken out from the inside of the heat treatment device, and the next mold steel can be quickly heat-treated, which improves the speed of mold steel processing, meets the actual use needs, and improves the use efficiency and effect of the heat treatment device.
