Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold heating technology, specifically to a heat conduction device for uniformizing mold heating. Background Technology
[0002] In industrial production, mold heating is a critical step in many manufacturing processes, especially in plastic injection molding, metal die casting, and composite material molding. The temperature uniformity and stability of the mold directly affect the molding quality, dimensional accuracy, and production efficiency of the product. Traditional mold heating methods typically use heating elements such as electric heating tubes, heating rods, or heating plates. These elements are usually installed inside or outside the mold, transferring heat to the mold surface through conduction, convection, or radiation. Due to the distribution of heating elements or limitations in the heat conduction path, uneven temperature distribution can easily occur on the mold surface, leading to localized overheating or underheating, which affects the molding quality of the product.

An adjusting rod is rotatably connected to one side of the movable plate. A connecting plate is rotatably connected to the bottom of the first partition. The end of the adjusting rod away from the movable plate is rotatably connected to the connecting plate. A connecting rod is slidably connected inside the first partition. A push plate is fixedly connected to the top of the connecting rod through the top of the first partition.
[0007] Preferably, a sleeve rod is fixedly connected to the bottom of the connecting plate, the outer side of the connecting rod is slidably connected to the sleeve rod, and a second partition is fixedly connected inside the heating box and directly below the first partition.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a uniform heat conduction device for mold heating, including a heating box 1 and a heating equipment body 2. The heating equipment body 2 is fixedly connected to one side of the heating box 1. A production mold 3 is detachably connected inside the heating box 1.

The connecting block 9 moves along the inside of the sliding groove 5. A heat conduction plate 10 is fixedly connected to the top of the connecting block 9. The movement of the connecting block 9 moves the heat conduction plate 10, so that the heat conduction plate 10 fits against the outer side of the production mold 3. The side of the connecting block 9 away from the heat conduction plate 10 is fixedly connected to the top of the connecting block 9. A movable plate 7 is fixedly connected, and the movable plate 7 moves along with the connecting block 9. An adjusting rod 8 is rotatably connected to one side of the movable plate 7, and the adjusting rod 8 moves along with the movable plate 7. A connecting plate 11 is rotatably connected to the bottom of the first partition 4, and the connecting plate 11 rotates at the bottom of the first partition 4. The end of the adjusting rod 8 away from the movable plate 7 is rotatably connected to the connecting plate 11, and the connecting plate 11 rotates along with the adjusting rod 8. A connecting rod 13 is slidably connected inside the first partition 4, and a push plate 6 is fixedly connected to the top of the connecting rod 13 through the top of the first partition 4. The moving connecting rod 13 moves along with the push plate 6, and the moving push plate 6 pushes the production mold 3 out of the heating box 1, making it convenient for the staff to take the production mold 3 out.
[0023] Furthermore, a sleeve rod 12 is fixedly connected to the bottom of the connecting plate 11. The sleeve rod 12 rotates, causing the connecting plate 11 to rotate as well. The outer side of the connecting rod 13 is slidably connected to the sleeve rod 12. The connecting rod 13 moves along the inside of the sleeve rod 12, and the sleeve rod 12 rotates along the outside of the connecting rod 13. A second partition 15 is fixedly connected inside the heating box 1 and directly below the first partition 4, further dividing the internal space of the heating box 1.
[0024] Furthermore, a servo motor 17 is fixedly connected to the top of the second partition 15, which better secures the servo motor 17.
[0025] Furthermore, the output end of the servo motor 17 is fixedly connected to the second gear 16, and the servo motor 17 rotates with the second gear 16 after being turned on.
[0026] Furthermore, a first gear 14 is fixedly connected to the outer side of the sleeve rod 12. The rotation of the first gear 14 causes the sleeve rod 12 to rotate. One side of the second gear 16 is meshed with the first gear 14. The rotation of the second gear 16 causes the first gear 14 to rotate.

[0028] In use, the production mold 3 is placed in the heating box 1, and the servo motor 17 is turned on. The servo motor 17 drives the second gear 16 to rotate, and the second gear 16 drives the sleeve rod 12 to rotate through the first gear 14. The sleeve rod 12 rotates along the outside of the connecting rod 13. At the same time, the sleeve rod 12 rotates, and the connecting plate 11 rotates, causing one end of the outer adjusting rod 8 to rotate. The adjusting rod 8 moves through the moving plate 7, and the connecting block 9 moves within the adjusting rod 8. The moving connecting block 9 moves the heat-conducting plate 10, so that the heat-conducting plate 10 fits against the outside of the production mold 3. The heat-conducting plate 10 can quickly and evenly transfer heat to the surface of the production mold 3. After the production mold 3 is heated, the heat-conducting plate 10 is moved away from the outside of the production mold 3, and the electric telescopic rod 18 is turned on. The electric telescopic rod 18 moves through the connecting rod 13, and the push plate 6 moves the production mold 3, so that the upper part of the production mold 3 leaves the heating box 1, making it easier for the staff to pick up the production mold 3.
