Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] refer to figure 1 , an indiscriminate low-pressure wheel hub casting mold, comprising an upper mold 9, a side mold 7, a lower mold 6, a wheel hub cavity 8, a pouring port 5, an aluminum liquid injection port 3, a hydraulic cylinder 1, a high-pressure forming channel 4 and a Press the piston 2, the pouring port 5 is set at the center of the lower mold 6, the aluminum liquid injection port 3 is located on one side of the bottom of the lower die 6, and communicates with the pouring port 5 through a high pressure forming channel 4, the hydraulic cylinder 1 is fixed on the lower mold 6, and its shaft is arranged horizontally. The pressurizing piston 2 is fixed on the shaft of the hydraulic cylinder 1 and extends into the high-pressure forming channel 4.
[0015] The principle is: after the mold is closed, aluminum liquid is injected at low pressure through...
