A tandem water spot cooling device for a top die. The device includes a spot cooling device main body, a lower sealing plate, an outer-ring circular track, an inner-ring serpentine passage, outer-ring flow dividing baffles, inner-ring flow dividing baffles, outer-ring through holes, inner-ring through holes, bolt hole reservation positions, stripper rod reservation positions, and water inlet and outlet connection through holes.

Tandem water spot cooling device for top die

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.

Water cooled mold for casting aluminum alloy wheels and manufacturing method thereof

The present invention provides a water spot cooling apparatus, a water spot cooling method for casting a mold, a method for manufacturing the water spot cooling apparatus and use of the water spot cooling apparatus. The technical solution of the present invention has the following advantages: spot cooling of multiple spots can be realized on each side mold by using only one water inlet pipeline, thereby saving the water cooling pipeline and facilitating field installation; the water inlet and outlet are integrated on a main body, thereby facilitating field implementation; the whole apparatus is easy to process, convenient to maintain, and low in manufacturing cost; and it is not restricted by the product structure and facilitates promotion.

Closed side mold water spot cooling apparatus, manufacturing method and use thereof

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.
