Automobile hub low pressure casting vacuum water cooling mold system

Abstract

The invention relates to an automobile wheel hub low-pressure casting vacuum water cooling mold system. A low-pressure casting mold comprises an upper die, a lower die and four side molds; the upper die, the lower die and the four side molds are combined to form into a casting chamber of a wheel hub to be cast; a cooling system comprises a water flow control cabinet, a water storage tank, a water storage buffer and a vacuum pump; the water flow control cabinet is communicated with a low-pressure casting machine platform through an input water pipe; the low-pressure casting machine platform is communicated with the water storage tank through an output water pipe; the water storage tank is connected with a water return pipe; cooling devices which are connected with the input water pipe and the output water pipe respectively are arranged inside empty chambers of the upper die, the lower die and the four side molds. The automobile wheel hub low-pressure casting vacuum water cooling mold system has the advantages of being scientific in design, reasonable in structure, convenient to operate, environment-friendly, high in cooling intensity and good in cooling effect, effectively improving the production efficiency, enabling the cooling devices in the mold to be uniformly arranged and the water flow speed to be adjustable, significantly reducing the production cost, improving the working environment and reducing the labor intensity of operating personnel.

Description

technical field

[0001] The invention belongs to the field of automobile manufacturing, and relates to automobile hub casting equipment, in particular to a vacuum water-cooled mold system for low-pressure casting of automobile hubs. Background technique

[0002] The wheel hub is an important part of the car, which has a great influence on the overall performance of the vehicle. The alloy wheel hub has the advantages of light weight, small inertial resistance, high manufacturing precision, and good heat dissipation performance, which is conducive to improving the straight-line driving performance of the car and reducing tire rolling resistance. At present, the automobile wheel hub on the market is mainly based on aluminum alloy. During the casting and cooling process of alloy wheels, factors such as excessive cooling speed or uneven cooling speed will cause defects such as shrinkage deformation, internal air holes and cracks in the alloy wheels, which will affect the strength ...
