[0006] Through the above scheme, the aluminum alloy stock solution can be injected into the lower mold through the injection hole. After the injection, a water pump can be used to draw cold water into the cavity through the water inlet pipe. When the cold water fills the cavity, it is discharged outward through the water outlet pipe, so that the water in the cavity is flowing living water, which can continuously take away the heat of the aluminum alloy stock solution, effectively improve the cooling speed, and accelerate the forming of the wheel hub. After the wheel hub is cooled and formed, the C-plate can be driven to rise through the lifting assembly, and then the upper mold can be driven to rise, so that the upper mold is separated from the lower mold. At the same time, the C-plate will rise together with the movable rod during the rising process, and then rise with the top block, so that the top block will eject the wheel hub formed in the lower mold, and complete the demolding, which is convenient for the staff to remove the wheel hub from the lower mold without the need for additional demolding tools, which is more convenient.

[0007] Preferably, the lifting assembly includes a motor, a threaded rod connected to an output shaft of the motor, and a slider screwed to the threaded rod.

[0008] Through the above solution, the motor can drive the threaded rod to rotate, so that the slider moves upward in the slide groove.

[0009] Preferably, an air outlet is formed at one end of the outer wall of the top of the upper mold.

[0010] Through the above solution, it is convenient to discharge the air in the lower mold to the outside.

[0011] Preferably, fixing holes are provided at four corners of the outer wall at the top of the bottom plate.

[0012] Through the above solution, it is convenient to fix the base plate to the ground.

[0013] Preferably, the slider is slidably connected to the inner wall of the slide groove, a threaded through hole is opened on the outer wall at the top of the slider, and the slider is threadedly connected to the threaded rod.

[0014] Through the above solution, the sliding block can be screwed onto the threaded rod.

[0015] Preferably, the C-shaped plate is fixed on the outer wall of the slider.

[0016] Through the above solution, the rise of the slider can drive the C-shaped plate to rise.

[0017] Preferably, the motor is connected to a control switch via a wire, and the control switch is connected to an external power source via a power line.

[0018] Through the above scheme, the motor can be powered on and run.

[0019] The beneficial effects of the utility model are:

[0020] Aluminum alloy stock liquid can be injected into the lower mold through the injection hole. After the injection, a water pump can be used to draw cold water into the cavity through the water inlet pipe, and the cold water is then discharged outward through the water outlet pipe, so that there is flowing living water in the cavity, which can continuously take away the heat of the aluminum alloy stock liquid, effectively improve the cooling speed, and accelerate the forming of the wheel hub. After the wheel hub is cooled and formed, the C-plate can be driven up by the lifting assembly to separate the upper mold from the lower mold. At the same time, the C-plate will rise against the movable rod and the ejector block during the rising process, and the wheel hub formed in the lower mold will be ejected through the ejector block to complete the demolding. No additional demolding tools are required, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
