An opening 30 is provided on the side of the mounting seat 26, and 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, and the two ends of the water channel 13 are respectively connected to the outer peripheral surface of the connecting pipe 11, the lower end of the water channel 12 is connected to the lower end surface 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, and 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 13 is connected to the opening 1 30, the lower end of the water channel 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. The lower mold 2 is provided with a connecting pipe 18, the upper end of the connecting pipe 18 can extend into the moving hole 10, and the connecting pipe 18 connects the lower mold cooling cavity 5 and the water channel 12. A sealing plug 28 is provided in the docking hole 27, and a spring 3 29 is connected to the upper part of the sealing plug 28, and the upper end of the spring 3 29 is connected to the top of the docking hole 27.

[0023] Furthermore, an installation cavity 14 is opened in the side mold 3, and a connecting pipe 11 is arranged through the installation cavity 14. The outer periphery of the connecting pipe 11 located in the installation cavity 14 is connected to a limiting ring 15. The lower part of the limiting ring 15 is connected to a spring 16, and the lower end of the spring 16 is connected to the bottom of the installation cavity 14.

[0024] Furthermore, an installation cavity 17 is provided in the lower mold 2, and the installation cavity 17 is located above the lower mold cooling cavity 5. A connecting pipe 18 is arranged to pass through the installation cavity 17, and the lower end of the connecting pipe 18 is located in the lower mold cooling cavity 5. The outer periphery of the connecting pipe 18 located in the installation cavity 17 is connected with a limiting ring 19, and a support ring 20 is provided below the limiting ring 19.

A guiding slope 25 is provided at the upper end of the connecting pipe 18.

[0025] Under normal conditions, under the action of the installation cavity 14, the connecting pipe 11 is located in the moving hole 10, and the two ends are not exposed, so as not to cause interference. The inlet and outlet ends of the side mold cooling cavity 6 are in contact with the side of the connecting pipe 11, so that the side mold cooling cavity 6 is closed, and the cooling water remaining in the side mold cooling cavity 6 will not flow out. Under the action of the spring 3 29, the sealing plug 28 is located at the lower end and abuts against the opening 30, so as to play a sealing role, and the cooling water in the upper mold cooling cavity 7 will not flow out.

[0026] When the side mold 3 moves to the top of the lower mold 2, the guiding slope 25 of the connecting pipe 18 is set toward the side mold 3. When the side mold 3 moves, it can resist the connecting pipe 18 to move it downward. After the side mold 3 moves into place, the connecting pipe 18 rises under the action of the spring 21, and the upper end of the connecting pipe 18 extends into the moving hole 10, and lifts the connecting pipe 1 11, so that the upper end of the connecting pipe 11 extends out of the moving hole 10. At this time, the lower end of the connecting pipe 18 is connected to the lower mold cooling cavity 5, and the upper end extends into the moving hole 10 and is connected to the lower end of the water channel 12.

When the upper mold 4 moves downward, the mounting seat 26 is aligned with the end of the connecting pipe 11 extending out of the moving hole 10, so that the upper end of the connecting pipe 11 is inserted into the docking hole 27 to push the sealing plug 28 open, and the exposed opening 130 is connected with the upper end of the water channel 2 13. In this way, the lower mold cooling cavity 5, the side mold cooling cavity 6 and the upper mold cooling cavity 7 are connected, and the cooling water mechanism 9 supplies cooling water to the lower mold cooling cavity 5, and the cooling water will enter the side mold cooling cavity 6 and the upper mold cooling cavity 7 to cool the lower mold 2, the side mold 3 and the upper mold 4, and accelerate the cooling speed of the internal casting wheel hub. The cooling water flows from bottom to top, so that the wheel hub is formed from bottom to top, which is convenient for filling materials in the unsolidified part of the upper part.

[0027] After the hub is formed, the cooling water mechanism 9 can extract cooling water from the upper mold cooling cavity 7, the side mold cooling cavity 6, and the lower mold cooling cavity 5. During demolding, the upper mold 4 rises and leaves the side mold 3, and the driving motor 23 drives the driving gear 24 to rotate. The driving gear 24 drives the connecting pipe 2 18 to rotate 180 degrees through the gear ring 22, so that the guiding bevel 25 faces inward. When the side mold 3 moves outward, the connecting pipe 2 18 can be pressed down by the guiding bevel 25, and the connecting pipe 2 18 will not affect the detachment of the side mold 3. After the side mold 3 moves outward, the connecting pipe 1 11 can drop back to its original position.

[0028] Further, the lower part of the lower mold 2 is connected to a support sleeve 31, a water inlet pipe 32 is arranged in the support sleeve 31, the upper end of the water inlet pipe 32 is connected to the lower mold cooling cavity 5, an opening 2 33 is provided on the outer periphery of the support sleeve 31, the inner end of the opening 2 33 is connected to the water inlet pipe 32, the outer end of the opening 2 33 is connected to the outer peripheral surface of the support sleeve 31, and the base 1 is connected to the opening 2 33. It also includes a base 1, a cooling water mechanism 9 is installed on the base 1, a sleeve 34 is sleeved on the support sleeve 31, an annular groove 1 35 and an annular groove 2 37 are arranged in the sleeve 34, the annular groove 1 35 and the annular groove 2 37 are distributed along the axial direction of the sleeve 34, a connecting hole 1 36 is connected to the annular groove 1 35, the other end of the connecting hole 1 36 is connected to the lower end surface of the sleeve 34, a connecting pipe 3 38 is connected to the annular groove 2 37, the other end of the connecting pipe 3 38 is connected to the lower end surface of the sleeve 34;

[0029] A lifting mechanism 39 is provided on the base 1, and the lifting mechanism 39 is driven and connected with a connecting rod 40, and the 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 43 is connected to the water pump 42, and the other end of the water pump 43 is connected to the lower end of the connecting pipe three 38. A water supply pipe 46 is connected to the water supply pump 45, and the other end of the water supply pipe 46 is connected to the lower end of the connecting hole one 36.

[0030] The sleeve 34 is lifted and lowered by driving the connecting rod 40 through the lifting mechanism 39, and the height of the annular groove 1 35 and the annular groove 2 37 can be adjusted. When the annular groove 1 35 is relatively connected to the opening 2 33, the cooling water in the cooler 44 is pumped into the cooling cavity by the water supply pump 45, and the water passing through the cooling cavity enters the water storage box 8 for collection. After the cooling is completed, the height of the sleeve 34 is adjusted to make the annular groove 2 37 relatively connected to the opening 2 33. At this time, the water in the water storage box 8 can be pumped back by the water pump 42, and 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 has a sealing effect.

[0032] Furthermore, since the sleeve 34 needs to be raised and lowered, the lengths of the water extraction pipe 43 and the water supply pipe 46 need to be able to be changed, and the water extraction pipe 43 and the water supply pipe 46 are set as telescopic pipes to meet the needs.
