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 relates to a method for drilling in steering knuckles, which comprises locating a casted steering knuckle onto a drilling fixture for a steering knuckle, and aligning the center lines of the maching points of the left and right pieces of the steering knuckle. The method provided by the present invention can meet the requirement for simultaneously drilling the left and right symmetrical pieces of the steering knuckle when in use, and in the meantime, has outstanding advantages of advance technology, high positioning precision, firmness in positioning, high machining efficiency and the like.
Abstract:
The present invention provides a side-mold water spot-cooling device for cooling a casting mold, a manufacturing method thereof and a method for cooling a casting mold by the device. The technical solution of the present invention has the following technical effects: an open-type backwater structure is employed, not only eliminating the back pressure from the backwater process without adding the supercharging equipment, but also reducing the investment costs of the equipment; reducing requirements for the sealing elements, thereby reducing costs for fittings; greatly reducing use of the joints and reducing the manufacturing, maintenance difficulty and costs of the mold; and the structure is substantially the same as that of the air-cooled mold and is easy for promotion.
