Problems solved by technology

[0002] Compared with the ever-changing advanced wheel production technology (such as forging, extrusion, spinning, etc.), the traditional low-pressure hub production technology has many problems: the low-pressure production hub is mainly reflected in the loose organizational structure, which is easy to generate various shrinkage cavities and scrap If it is not detected by X-ray in time (shrinkage cavity exists inside the product and cannot be seen by the naked eye), if it is discovered, it will cause great personal and property safety hazards if it enters the market, and cause immeasurable losses to

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...

Abstract

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-pressure casting, forging, extrusion and spinning are effectively integrated, the high-quality wheel hub which is equivalent to a wheel hub produced through the forging technology is produced with the lowest cost investment and the highest cost performance, the production cost of the high-quality wheel hub is greatly reduced, and the production efficiency is improved; and the casting mold has excellent economic and social benefits.

Background technique [0002] Compared with the ever-changing advanced wheel production technology (such as forging, extrusion, spinning, etc.), the traditional low-pressure hub production technology has many problems: the low-pressure production hub is mainly reflected in the loose organizational structure, which is easy to generate various shrinkage cavities and scrap If it is not detected by X-ray in time (shrinkage cavity exists inside the product and cannot be seen by the naked eye), it will cause great personal and property safety hazards if it enters the market, and cause immeasurable losses to the society and individual families. At present, the production of wheel hubs in the world is dominated by low-pressure production technology, because in addition to low-pressure and gravity casting technology...
