Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a quick-change metal casting hot pressing forming device, including a base 9, a lower mold 5 disposed on the top side of the base 9, four columns 4 fixedly connected to the top side of the base 9, a top plate 2 fixedly connected to the top side of the four columns 4, a hydraulic press 1 installed inside the top plate 2, a sliding plate 3 fixedly connected to the drive end of the hydraulic press 1, the sliding plate 3 slidably connected to the outer wall of the columns 4, and an upper mold 15 connected to the bottom side of the sliding plate 3. The hydraulic press 1 drives the sliding plate 3 to slide up and down, causing the upper mold 15 to move closer to the lower mold 5, thereby hot pressing the metal material. (Refer to...) Figure 6 and Figure 7 Heating wires 18 are fixedly connected inside both the lower mold 5 and the upper mold 15. The metal material is heated by the heating wires 18 to perform hot pressing. Both the lower mold 5 and the upper mold 15 have cavities inside, and cooling pipes 19 are fixedly connected inside the cavities. (Refer to...) Figures 3-5Four fixing blocks 11 are fixedly connected to the top side of the base 9 and the bottom side of the slide plate 3. A fixing tube 13 is fixedly connected to one side of the fixing block 11. A plug rod 16 is slidably connected inside the fixing tube 13. Two fixing plates 14 are fixedly connected to the left and right sides of the lower mold 5 and the upper mold 15. The plug rod 16 is inserted into the inside of the fixing plate 14. By inserting the plug rod 16 into the fixing plate 14, the fixing plate 14 is fixed to the base 9 or the slide plate 3. A threaded rod 17 is threadedly connected inside the plug rod 16. One end of the fixing tube 13 is rotatably connected to the handle 12 through the damping shaft. The end of the threaded rod 17 is rotatably connected to the inside of the fixing tube 13, and the end of the threaded rod 17 is fixedly connected to the inside of the handle 12. The threaded rod 17 is rotated by the handle 12, so that the threaded rod 17 drives the plug rod 16 to insert into or disengage from the fixing plate 14.

[0030] Reference Figure 1 , Figure 8 and Figure 9 Water tanks 10 are installed on both the front and rear sides of the base 9 to store water for cooling. A spiral tube 6 is fixedly connected to the inner wall of the water tank 10 to extend the residence time of the cooling water and increase the cooling time. A water pump 8 is installed on the bottom of the water tank 10. The bottom end of the spiral tube 6 is fixedly connected to the input end of the water pump 8, and the output end of the water pump 8 is fixedly connected to a water delivery pipe 20. A return water pipe 21 is fixedly connected to the top end of the spiral tube 6. The water pump 8 delivers the cooling water from the spiral tube 6 to the water delivery pipe 20, allowing the cooling water to enter the cooling pipe 19 through the water delivery pipe 20 to cool the lower mold 5 and the upper mold 15. The metal material is cooled to set its shape, and the cooling water in the cooling pipe 19 is returned to the spiral pipe 6 for cooling through the return water pipe 21. The ends of the water supply pipe 20 and the return water pipe 21 are fixedly connected to metal pipes 22. The end of the cooling pipe 19 is connected to the metal pipe 22 through a flange. The metal pipe 22 and the flange allow the cooling pipe 19 to be disassembled and installed along with the upper mold 5 or the lower mold 15. The bottom side of the water tank 10 is fixedly connected to a drain pipe 7. The water heated to a certain temperature by the cooling water in the water tank 10 is discharged to the place where the water is needed, thereby achieving the effect of heat recovery.

[0031] Working principle: First, place the lower mold 5 and upper mold 15 onto the base 9 and slide plate 3 respectively. Then, rotate the handle 12 to rotate the threaded rod 17, causing the threaded rod 17 to drive the insert rod 16 to insert into the fixing plate 14, fixing the fixing plate 14 onto the base 9 or slide plate 3. This fixes the lower mold 5 and upper mold 15 onto the base 9 and upper mold 15 respectively. Then, place the liquid or plastic metal billet into the lower mold 5. Next, start the hydraulic press 1 to drive the slide plate 3 to slide downwards, causing the slide plate 3 to bring the upper mold 15 closer to the lower mold 5 and finally press them together. Simultaneously, start the heating wire 18 to heat the metal material, thereby performing hot pressing on the metal material, allowing it to be hot-pressed into shape. After hot pressing, turn off the heating wire 18. The water pump 8 is started to deliver cooling water from the spiral tube 6 to the water supply pipe 20, so that the cooling water enters the cooling pipe 19 through the water supply pipe 20 to cool the metal material in the lower mold 5 and the upper mold 15, so that the metal material is shaped. The cooling water in the cooling pipe 19 is returned to the spiral tube 6 through the return water pipe 21 for cooling. After cooling is completed, the hydraulic press 1 is started to drive the slide plate 3 upward to separate the upper mold 15 and the lower mold 5. Then the hot-pressed metal material is taken out to complete one work cycle. When the water in the water tank 10 is heated to a certain temperature by the cooling water, the water heated to a certain temperature in the water tank 10 is discharged to the place where the water is used through the drain pipe 7, thereby achieving the effect of heat recovery.
