Undifferentiated low-pressure and high-pressure casting mold for wheel hub

The invention relates to the technical field of low-pressure casting, in particular to an undifferentiated low-pressure and high-pressure casting mold for a wheel hub. The casting mold comprises an upper mold, edge molds, a lower mold, a wheel hub mold cavity, a sprue gate, a molten aluminum injection opening, an oil pressure cylinder, a high-pressure forming channel and a pressurization piston; the sprue gate is formed in the center of the lower mold, and the molten aluminum injection opening is located on one side of the bottom of the lower mold and communicates with the sprue gate through the high-pressure forming channel; and the oil pressure cylinder is fixed on the lower mold, and a shaft rod of the oil pressure cylinder is horizontally arranged. On the basis of an existing low-pressure casting technology, corresponding improvement measures are taken, and undifferentiated pressurization and high-pressure modes are adopted to realize the effect of high-pressure forging; the technologies such as low-press
