Abstract: The present invention provides a water spot cooling device of a bottom mold for wheel hub casting, a method for cooling a bottom mold by using the device, and a method for manufacturing the device. The device and the method of the present invention have the advantages that multi-path spot cooling required by spoke cooling is integrated into one device; the influence of backwater on the mold is eliminated and stable production is benefited; the effluent water from the multi-path spot cooling is gathered to one backwater opening through a backwater crossing and a backwater annular passage, thereby simplifying a backwater device and making the pipeline connection of the device simpler; and there is no special part in the whole device so that the machining cost is reduced and the maintenance is more convenient.

Abstract: The present invention provides a water cooled mold for casting aluminum alloy wheels and a manufacturing method thereof. The water cooled mold is provided with first-type water cooling channels with high heat exchange efficiency and second-type water cooling channels with low heat exchange efficiency. The first-type water cooling channels are concave grooves through which cooling water flows, and a cooling surface of the mold is in contact with open surfaces of the concave grooves. The second-type water cooling channels are grooves with stainless steel pipes, and the stainless steel pipes are in contact with the cooling surface of the mold. The second-type water cooling channels are installed on mold portions corresponding to wheel window positions of a cavity, and the first-type water cooling channels are installed on mold portions corresponding to spokes, flanges and rims of the cavity. The water cooled mold of the present invention is capable of accurately controlling a direction and a range of cooling within a three-dimensional space; the use of a thermal insulating groove is omitted so that the mold can be manufactured more simply and the service life of the mold can be prolonged; the cooling efficiency is high and resources are saved; and the whole device is simple to manufacture and low in cost.

Abstract: An automobile hub with a hollow rim includes a wheel disc and the rim with at least one hollow cavity, in which the rim includes at least two mutually nested rings and an axial end cap at the same ends of the at least two rings, and the hollow cavity consists of the rings and the axial end cap. The outer side of one end of the wheel disc includes axial rim mounting grooves, and the rim is inserted into the rim mounting grooves and fixed to the wheel disc through the end without the axial end cap. By employing the automobile hub with the hollow rim, the hub assembling method, and the automobile having the hub, the weight of the hub can be further reduced, and the hub has sufficient strength.
