Problems solved by technology

[0002] The automobile wheel hub is a part installed on the automobile to support the tire. Its blanks are mostly made of aluminum alloy casting. Due to the complex shape of the automobile wheel hub and high requirements for metal density and strength, therefore, in In the casting of automobile wheel hub blanks, people often choose the low-pressure casting method with uniform molecular distribution and small pores. Low-pressure casting uses low pressure to press the liquid alloy into the mold; but this casting method exists: fixed mold and dynamic mold When the mold is closed, the equipment needs to have enough pressure, otherwise the reliability is low and the curved hub panel is difficult to remove from the cavity of the fixed mold after casting
