[0020] like Figures 1-4 As shown, a cooling device for a wheel hub mold includes a lower mold 2, a side mold 3 slidably disposed on the upper part of the lower mold 2, an upper mold 4 disposed on the upper part of the side mold 3, a lower mold cooling cavity 5 disposed inside the lower mold 2, a side mold cooling cavity 6 disposed inside the side mold 3, and an upper mold cooling cavity 7 disposed on the upper part of the upper mold 4. A movable hole 10 is opened in the side mold 3, and a connecting pipe 11 is movably disposed in the movable hole 10. A water channel is opened in the connecting pipe 11, which can connect the lower mold cooling cavity 5, the side mold cooling cavity 6, and the upper mold cooling cavity 7.

[0021] Furthermore, a mounting base 26 is provided at one end of the upper mold cooling cavity 7, and a water storage box 8 is connected to the other end of the upper mold cooling cavity 7. The water storage box 8 is located on the upper part of the upper mold 4. A docking hole 27 is provided in the mounting base 26. The lower end of the docking hole 27 is connected to the lower end face of the upper mold 4. An opening 30 is provided on the side of the mounting base 26. The inner end of the opening 30 is connected to the docking hole 27, and the outer end of the opening 30 is connected to the upper mold cooling cavity 7. A water channel 13 and a water channel 12 are provided in the connecting pipe 11. The two ends of the water channel 13 are connected to the outer peripheral surface of the connecting pipe 11, respectively. The lower end of the water channel 12 is connected to the lower end face of the connecting pipe 11, and the upper end of the water channel 12 is connected to the outer peripheral surface of the connecting pipe 11. The side mold cooling cavity 6 includes an inlet end and an outlet end. The inlet end is located below the outlet end.

[0022] When the upper end of the connecting pipe 11 extends into the docking hole 27, the upper end of the water channel 2 13 is connected to the opening 30, the lower end of the water channel 2 13 is connected to the outlet end of the side mold cooling cavity 6, and the upper end of the water channel 12 is connected to the inlet end of the side mold cooling cavity 6. A connecting pipe 2 18 is provided inside the lower mold 2, and the upper end of the connecting pipe 2 18 can extend into the moving hole 10. The connecting pipe 2 18 connects the lower mold cooling cavity 5 and the water channel 1 12. A sealing plug 28 is provided inside the docking hole 27, and a spring 3 29 is connected to the upper part of the sealing plug 28. The upper end of the spring 3 29 is connected to the top end of the docking hole 27.

[0023] Furthermore, a mounting cavity 14 is provided inside the side mold 3, and a connecting pipe 11 is provided through the mounting cavity 14. The portion of the connecting pipe 11 located inside the mounting cavity 14 is connected to a limiting ring 15. A spring 16 is connected to the lower part of the limiting ring 15, and the lower end of the spring 16 is connected to the bottom of the mounting cavity 14.

[0024] Furthermore, a second mounting cavity 17 is formed inside the lower mold 2, and the second mounting cavity 17 is located above the lower mold cooling cavity 5. A second connecting pipe 18 is set through the second mounting cavity 17, and the lower end of the second connecting pipe 18 is located inside the lower mold cooling cavity 5. The portion of the outer periphery of the second connecting pipe 18 located inside the second mounting cavity 17 is connected to a second limiting ring 19. A support ring 20 is set below the second limiting ring 19. A second spring 21 is connected to the lower part of the support ring 20. The lower end of the second spring 21 is connected to the bottom of the second mounting cavity 17. A toothed ring 22 is connected to the outer periphery of the second connecting pipe 18. The toothed ring 22 is located below the support ring 20. A drive motor 23 is set inside the second mounting cavity 17. The drive motor 23 drives a drive gear 24, which meshes with the toothed ring 22. A guide slope 25 is set at the upper end of the second connecting pipe 18.

[0025] Under normal conditions, with the action of mounting cavity 14, connecting pipe 11 is located inside moving hole 10, with both ends not exposed, thus preventing interference. The inlet and outlet ends of side mold cooling cavity 6 contact the side of connecting pipe 11, thereby sealing side mold cooling cavity 6 and preventing residual cooling water in side mold cooling cavity 6 from flowing out. Under the action of spring 29, sealing plug 28 is located at the lower end and abuts against opening 30, thus achieving a sealing effect and preventing cooling water in upper mold cooling cavity 7 from flowing out.

[0026] When the side mold 3 moves above the lower mold 2, the guide slope 25 of the connecting pipe 2 18 faces the side mold 3. During the movement of the side mold 3, it abuts against the connecting pipe 2 18, causing it to move downwards. After the side mold 3 is in position, the connecting pipe 2 18 rises under the action of the spring 2 21, with its upper end extending into the moving hole 10, and lifting the connecting pipe 1 11 so that its upper end extends out of the moving hole 10. At this time, the lower end of the connecting pipe 2 18 connects to the lower mold cooling cavity 5, and its upper end extends into the moving hole 10 and connects to the lower end of the water channel 1 12. Simultaneously, the upper end of the water channel 1 12 connects to the inlet end of the side mold cooling cavity 6, and the outlet end of the side mold cooling cavity 6 connects to the lower end of the water channel 2 13. When the upper mold 4 moves downward, the mounting base 26 aligns with the end of the connecting pipe 11 extending from the moving hole 10, causing the upper end of the connecting pipe 11 to insert into the mating hole 27, pushing open the sealing plug 28. The exposed opening 30 connects with the upper end of the water channel 13. This connects the lower mold cooling chamber 5, the side mold cooling chamber 6, and the upper mold cooling chamber 7. The cooling water mechanism 9 supplies cooling water to the lower mold cooling chamber 5, which then enters the side mold cooling chamber 6 and the upper mold cooling chamber 7, cooling the lower mold 2, the side mold 3, and the upper mold 4 and accelerating the cooling speed of the internal cast wheel hub. Furthermore, the cooling water flows from bottom to top, causing the wheel hub to form from bottom to top, facilitating the replenishment of material in the unsolidified upper part.

[0027] After the wheel hub is formed, the cooling water mechanism 9 can extract cooling water from the upper mold cooling chamber 7, the side mold cooling chamber 6, and the lower mold cooling chamber 5. During demolding, the upper mold 4 rises and separates from the side mold 3. The drive motor 23 drives the drive gear 24 to rotate. The drive gear 24 drives the connecting pipe 18 to rotate 180 degrees through the gear ring 22, so that the guide slope 25 faces inward. When the side mold 3 moves outward, the connecting pipe 18 can be pressed down by the guide slope 25, so that the connecting pipe 18 will not affect the demolding of the side mold 3. After the side mold 3 moves outward, the connecting pipe 11 can descend back to its original position.

[0028] Furthermore, a support sleeve 31 is connected to the lower part of the lower mold 2. A water inlet pipe 32 is provided inside the support sleeve 31. The upper end of the water inlet pipe 32 is connected to the cooling cavity 5 of the lower mold. An opening 33 is opened on the outer periphery of the support sleeve 31. The inner end of the opening 33 is connected to the water inlet pipe 32, and the outer end of the opening 33 is connected to the outer periphery of the support sleeve 31. The base 1 is connected to the opening 33. The system also includes a base 1. A cooling water mechanism 9 is installed on the base 1. A sleeve 34 is fitted on the support sleeve 31. An annular groove 35 and an annular groove 37 are opened inside the sleeve 34. The annular groove 35 and the annular groove 37 are distributed along the axial direction of the sleeve 34. A connecting hole 36 is connected to the annular groove 35. The other end of the connecting hole 36 is connected to the lower end face of the sleeve 34. A connecting pipe 38 is connected to the annular groove 37. The other end of the connecting pipe 38 is connected to the lower end face of the sleeve 34.

[0029] A lifting mechanism 39 is provided on the base 1. The lifting mechanism 39 is driven and connected to a connecting rod 40. A sleeve 34 is installed on the connecting rod 40. A cold water tank 41 and a cooler 44 are also provided on the base 1. A water pump 42 and a water supply pump 45 are respectively provided on the cold water tank 41 and the cooler 44. A water pump 42 is connected to a water pump 43. The other end of the water pump 43 is connected to the lower end of the connecting pipe 38. A water supply pipe 46 is connected to the water pump 45. The other end of the water supply pipe 46 is connected to the lower end of the connecting hole 36.

[0030] The lifting mechanism 39 drives the connecting rod 40 to raise and lower the sleeve 34, thereby adjusting the height of the first annular groove 35 and the second annular groove 37. When the first annular groove 35 is in relative communication with the second opening 33, the water supply pump 45 draws cooling water from the cooler 44 and pumps it into the cooling chamber. The water passing through the cooling chamber enters the water storage box 8 for collection. After cooling is completed, the height of the sleeve 34 is adjusted so that the second annular groove 37 is in relative communication with the second opening 33. At this time, the water pump 42 can pump the water back from the water storage box 8. The pumped-back cooling water is cooled by the cold water tank 41 and then enters the cooler 44 for storage.

[0031] Furthermore, a sealing ring 47 is provided at the outer end of the second opening 33, and the sealing ring 47 serves to seal the opening.

[0032] Furthermore, since the sleeve 34 needs to be raised and lowered, the lengths of the pumping pipe 43 and the supply pipe 46 need to be adjustable. Therefore, the pumping pipe 43 and the supply pipe 46 are designed as telescopic pipes to meet the requirements.

[0033] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
