[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: A heat treatment device for automobile die-casting molds includes a heating furnace 1. A exhaust chamber 2 is fixedly connected to the side wall of the heating furnace 1. A connecting pipe 3 is fixedly connected to the side wall of the exhaust chamber 2. A motor 4 is fixedly connected inside the connecting pipe 3. The output end of the motor 4 is fixedly connected to a first gear 5. The first gear 5 is rotatably connected inside the exhaust chamber 2. A second gear 6 is rotatably connected inside the exhaust chamber 2. The second gear 6 meshes with the first gear 5. A screw 7 is rotatably connected inside the exhaust chamber 2. The screw 7 is fixedly connected to the side wall of the second gear 6. A first fixed table 8 is fixedly connected inside the exhaust chamber 2. A slide column 9 is slidably connected inside the first fixed table 8. The slide column 9 is threadedly connected to the outer wall of the screw 7. A cooling assembly is provided on the top of the heating furnace 1 for exhausting gas from the top.

[0024] Specifically, start the motor 4. The motor 4 transmits the rotational force inside the connecting pipe 3 to drive the first gear 5 to start rotating inside the exhaust chamber 2. The rotation of the first gear 5 simultaneously drives the second gear 6 to rotate inside the exhaust chamber 2 through meshing with the second gear 6. The rotation of the second gear 6 further drives the screw 7 on its side wall to rotate. The rotation of the screw 7, through the threaded connection with the sliding column 9, pushes the sliding column 9 to slide inside the first fixed platform 8. The displacement of the sliding column 9 can control the exhaust holes inside the heating furnace 1 to achieve the blocking or release of the internal gas. This process ensures that harmful gases can be safely and effectively discharged when needed, avoiding potential harm and pollution to the human body and the environment. This design not only improves the safety of operation but also ensures the reliability and environmental protection performance of the heating furnace 1 during use.

[0025] Refer to Figure 3 , the cooling assembly includes a cooling pipe 10. The cooling pipe 10 is fixedly connected to the top of the heating furnace 1. Inside the cooling pipe 10, a second fixed platform 11 is fixedly connected. On the side wall of the second fixed platform 11, an inclined plate 15 is fixedly connected. On the side wall of the second fixed platform 11, a hydraulic push rod 12 is fixedly connected. The output end of the hydraulic push rod 12 is fixedly connected to a sliding platform 14. On the side wall of the second fixed platform 11, a slide rail 13 is fixedly connected. The sliding platform 14 is slidably connected to the side wall of the slide rail 13. On the side wall of the sliding platform 14, a rotating platform 16 is fixedly connected. Inside the rotating platform 16, a first rotating column 17 is rotatably connected. At the bottom of the first rotating column 17, a gas cooling head 18 is fixedly connected. At the top of the first rotating column 17, a second rotating column 19 is fixedly connected. At the top of the second rotating column 19, a connecting member 20 is fixedly connected. Inside the connecting member 20, a pulley 21 is rotatably connected. The pulley 21 is slidably connected to the side wall of the inclined plate 15.

[0026] Specifically, the hydraulic push rod 12 applies a pushing and pulling force to the sliding platform 14 through the side wall of the second fixed platform 11, pushing the sliding platform 14 to slide on the side wall of the slide rail 13. The sliding of the sliding platform 14 causes the synchronous displacement of the rotating platform 16 on its side wall. The displacement of the rotating platform 16 further drives the synchronous movement of the first rotating column 17 inside it. When the connecting member 20 at the top of the first rotating column 17 moves, the connecting member 20 contacts the inclined plate 15 and changes the angle through the rotation of the pulley 21, pushing the first rotating column 17 to rotate inside the rotating platform 16. This movement also causes the bottom rotating platform 16 to start rotating. This design can effectively expand the cooling range and improve the cooling efficiency. Through the rotation of the gas cooling head 18, the cooling device at the top of the heating furnace 1 can cover a wider area, ensuring uniform cooling of the entire top of the heating furnace 1, thereby effectively reducing the temperature inside the furnace, protecting the equipment, and ensuring the safety of operation.

[0027] Working principle: When it is necessary to release the gas inside the heating furnace 1, first start the motor 4. The motor 4 outputs a rotating force to the first gear 5 inside the connecting pipe 3, driving the first gear 5 to rotate inside the exhaust chamber 2. While the first gear 5 is rotating, it drives the second gear 6 to rotate inside the exhaust chamber 2 through its meshing relationship with the second gear 6. While the second gear 6 is rotating, it drives the screw 7 on its side wall to rotate. The rotation of the screw 7 can push the sliding column 9 to slide inside the first fixed platform 8 through the threaded connection relationship with the sliding column 9. The displacement of the sliding column 9 can block or release the exhaust holes inside the heating furnace 1, avoiding harm to the human body and the environment caused by harmful gas leakage. When it is necessary to cool the top of the heating furnace 1, start the hydraulic push rod 12. The hydraulic push rod 12 outputs a pushing and pulling force to the sliding table 14 on the side wall of the second fixed platform 11, driving the sliding table 14 to slide on the side wall of the slide rail 13. At this time, the sliding of the sliding table 14 can drive the turntable 16 on its side wall to displace synchronously. The displacement of the turntable 16 drives the first rotating column 17 inside it to displace synchronously. The second rotating column 19 at the top of the first rotating column 17 follows the movement. At this time, the connecting piece 20 at the top of the second rotating column 19 touches the inclined plate 15 and changes the angle of the connecting piece 20 through the rotation of the pulley 21, thereby driving the first rotating column 17 to rotate inside the turntable 16, and then driving the gas cooling head 18 at the bottom to rotate. This structure enables the gas cooling head 18 to expand the cooling range and improve the cooling efficiency when cooling the inside of the heating furnace 1.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
