[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping molds, hot forging molds, and die-casting molds. The quality of the mold directly affects the quality of the pressure processing process, the precision output of the product, and the production cost. Due to the different uses of various molds and complex working conditions, mold steel should have high hardness and strength.

[0039] The present invention provides a schematic diagram of the overall structure of an embodiment of a die steel heat treatment and quenching equipment, comprising:

The second motor 305 is electrically connected to the external power supply, and the mold steel heated in the quenching furnace is placed on the top of multiple receiving plates 311 respectively. By turning on the first motor 301, the lead screw 302 is driven to rotate, so that the slider 303 drives the movable frame 304 to move downward, and then the mold steel moves downward into the coolant inside the quenching pool 1 for quenching. By turning on the second motor 305, the rotating shaft 306 is driven to rotate, so that the turntable 307 rotates and drives multiple receiving plates 311 to rotate around the center of the turntable 307, so that the mold steel is fully in contact with the coolant, the cooling is more uniform, and uneven quenching hardness is avoided. The rotation of the rotating shaft 306 drives the first gear 308 to rotate at the same time, so that the multiple second gears 309 rotate at the same time, driving the multiple rotating rods 310 to rotate at the same time, and then the receiving plate 311 rotates in the opposite direction of the turntable 307, so that the receiving plate 311 always remains in a horizontal state to prevent the mold steel from falling.

[0041] It is worth noting that in order to quickly remove the coolant attached to the surface of the mold steel, specifically, the air drying component 4 includes a fixed tube 401, a plurality of ventilation holes 402 are opened on the side wall of the fixed tube 401, a first fan 403 is fixedly provided at one end of the fixed tube 401, a semiconductor cooling plate 404 is bonded to the side wall of the first fan 403, a heat dissipation fin 405 is bonded to the other side wall of the semiconductor cooling plate 404, a second fan 406 is fixedly provided at the other end of the fixed tube 401, an air supply pipe 407 is fixedly provided at the output end of the second fan 406, and the other end of the air supply pipe 407 passes through the side wall of the movable frame 304 The first fan 403 and the second fan 406 are electrically connected to the external power supply, and the air entering the ventilation hole 402 is cooled by the semiconductor refrigeration plate 404, and the heat exchange efficiency is improved by the heat dissipation fins 405. By turning on the second fan 406, the cooled air is transported to the air duct 407, thereby drying the coolant on the surface of the mold steel on the top of the receiving plate 311, saving time, facilitating subsequent processing, maintaining low temperature and improving the quenching effect of the mold steel, and by turning on the first fan 403, the semiconductor refrigeration plate 404 dissipates heat, and then the air in the ventilation hood 301 is continuously cooled.

[0042] In some embodiments, the semiconductor refrigeration chip 305 adopts a magnetic refrigeration chip. The magnetic refrigeration chip is a new type of refrigeration chip that uses a magnetic field to regulate the physical state of a magnetic material to achieve refrigeration. Its working principle includes the anti-magnetic capture effect, the spontaneous magneto-refrigeration effect, etc. It has the characteristics of high efficiency, energy saving, and no environmental pollution. Compared with traditional refrigeration technology, the magnetic refrigeration chip does not generate mechanical vibration and noise during the refrigeration process, and does not require the use of refrigerants. Therefore, it has a higher energy efficiency ratio and lower operating costs. At the same time, the magnetic refrigeration chip also has the advantages of fast response speed and high temperature control accuracy.

[0043] In some embodiments, the semiconductor refrigeration sheet 305 may also adopt a thermoelectric composite refrigeration sheet. The thermoelectric composite refrigeration sheet is a product that combines the advantages of traditional refrigerant refrigeration and Peltier refrigeration. It is usually composed of multiple Peltier refrigeration units, and realizes refrigeration through thermoelectric-thermomechanical coupling, which can achieve higher refrigeration efficiency and lower temperature. This type of refrigeration sheet is more complex in design, but its refrigeration performance is significantly improved. The thermoelectric composite refrigeration sheet not only inherits the advantages of no vibration and no noise of the Peltier refrigeration sheet, but also improves the refrigeration efficiency and temperature control accuracy through the combination of multiple units. At the same time, due to the optimization of its internal structure, the stability of the thermoelectric composite refrigeration sheet under long-term operation has also been significantly improved, providing reliable protection for high-end refrigeration equipment.

[0044] In some embodiments, the heat sink fins 405 can be set to a wavy line shape. The wavy heat sink can effectively enhance the wind conduction and also increase the aesthetics of the product. The wavy fins of the aluminum extruded radiator play a very important role in the heat dissipation process. The design of the wavy fins of the aluminum extruded radiator is intended to increase the surface area of the radiator, thereby improving the heat dissipation efficiency and allowing the system to more effectively transfer heat to the surrounding environment. Generally speaking, the surface area of the radiator is proportional to its heat dissipation efficiency. The design of the wavy fins of the aluminum extruded radiator effectively increases the surface area of the radiator, thereby greatly improving the heat dissipation efficiency of the radiator. The design of the wavy fins of the aluminum extruded radiator can also improve the heat transfer efficiency. The shape of the wavy fins can break the boundary layer of air on the surface of the fins, thereby increasing the surface area of heat transfer, allowing heat to be transferred from the surface of the radiator to the air faster, reducing heat accumulation inside the system, and preventing the system from overheating. The wavy fins of the aluminum extruded radiator can also increase the stability and reliability of the system, reduce the operating temperature of the system, and extend the service life of the system. The design of the wavy fins of the aluminum extruded radiator can also reduce the volume and weight of the system, improve the overall stability of the system, reduce the failure rate, and thus improve the reliability of the system.

[0045] In some embodiments, the thickness of a single heat sink fin 405 can be reduced, while the number and density of the heat sink fins 405 can be increased. By increasing the number and density of the heat sink fins, a larger heat sink area can be achieved within a limited volume. There are two ways to increase the number of heat sink fins and increase the length of the heat sink fins. One of the data reflected is the "thickness-to-height ratio" - that is, the ratio of the thickness of the heat sink fin to the height. The smaller this value is, the denser the heat sink fins per unit volume can be. The greater the number, the larger the surface area for effective heat dissipation, and the better the heat dissipation performance.

[0046] Next, in order to improve the stability of the mold steel, specifically, electric push rods 312 are fixed at both ends of the top of the receiving plate 311, and a clamping plate 313 is fixed at the output end of the electric push rod 312. The electric push rod 312 is electrically connected to the external power supply. By opening the two electric push rods 312, the two clamping plates 313 are driven to move inward at the same time to clamp the mold steel, thereby improving the stability of the mold steel and preventing it from falling during quenching.

[0047] At the same time, in order to improve the quenching effect of the mold steel, specifically, the waterproof grade of the electric push rod 312 is IP66W, and multiple through grooves 314 are opened on the top of the receiving plate 311 and the side wall of the clamping plate 313. The IP66W electric push rod 312 is completely dustproof and can withstand high-pressure water columns, which is convenient for adapting to the environment required for mold steel quenching. The through grooves 314 facilitate the circulation of coolant, which makes the quenching and cooling of the mold steel more uniform.

[0048] Furthermore, in order to facilitate the limitation of the movement of the slider 303, specifically, a plurality of limit rods 315 located at the bottom of the inner cavity of the quenching pool 1 are fixed on the top of the inner cavity of the fixed frame 2, and the plurality of limit rods 315 are slidably connected to the slider 303. Through the plurality of limit rods 315 slidably connected to the slider 303, the slider 303 is prevented from rotating with the rotation of the screw 302.

[0049] It is worth noting that in order to prevent the second motor 305 from being damaged, specifically, the second motor 305 is a waterproof motor, and a fixing plate 316 located on the side wall of the movable frame 304 is fixed at the bottom of the second motor 305. The fixing plate 316 facilitates improving the stability of the second motor 305 during operation and preventing it from falling.

[0050] Subsequently, in order to make the movement of the movable frame 304 more stable, specifically, the cross-section of the fixed frame 2 is L-shaped, and the screw 302 is rotatably connected to the bottom of the inner cavity of the quenching pool 1. By rotatably connecting the screw 302 to the bottom of the inner cavity of the quenching pool 1, the screw 302 is made more stable, thereby improving the stability of the movable frame 304 during movement.

[0051] Secondly, in order to improve the heat exchange effect, specifically, the side walls of the semiconductor refrigeration plate 305 are coated with thermal grease, and the heat sink fins 405 are made of copper-nickel alloy. The thermal grease is heat-resistant and has excellent thermal conductivity. The heat exchange effect is improved by using the heat sink fins 405 made of copper-nickel alloy.

[0052] Then, in order to save time, specifically, the other end of the air duct 407 passes through the side wall of the movable frame 304, and the position of the other end of the air duct 407 matches the top center of the receiving plate 311. The air duct 407 matching the top center of the receiving plate 311 facilitates the cold air to be blown to the mold steel more accurately.

[0053] Finally, in order to prevent the mold steel from being contaminated by the coolant, a drain pipe 5 is fixedly provided at the bottom of the side wall of the quenching pool 1, and a solenoid valve 6 is fixedly provided on the outer wall of the drain pipe 5. The solenoid valve 6 controls the coolant inside the quenching pool 1 to be discharged from the drain pipe 5 for replacement, thereby avoiding the coolant contamination after long-term use that affects the quality of the mold steel finished product.

Needless to say, the content protected by the present invention does not involve improvements to the internal structure and method:

[0063] 2: Coat both sides of the semiconductor refrigeration sheet 404 with thermal grease, adhere the semiconductor refrigeration sheet 404 to the side wall of the second fan 406, adhere the heat dissipation fins 405 to the side wall of the semiconductor refrigeration sheet 404, start the semiconductor refrigeration sheet 404 to cool the air entering the ventilation hole 402, start the second fan 406 to transport the cooled air to the air duct 407, thereby drying the coolant on the mold steel surface at the top of the receiving plate 311, and start the first fan 403 to dissipate heat from the semiconductor refrigeration sheet 404.
