A mold package for casting a wheel assembly includes a sand printed drag mold having a cavity with a chill support chamber and a metal chill received in the support chamber. The mold package further includes at least one sand printed mold insert received in the cavity of the sand printed drag mold and a sand printed cope mold coupled to the sand printed drag mold such that a casting cavity for the wheel assembly is created by the exterior inner surfaces of the cope mold, the drag mold and the at least one insert.

A die cooling system for cooling a cast wheel for an automotive vehicle is provided that includes a die, multiple thermocouples embedded in the die, which measure the actual cast metal temperature, adjustable cooling valves, and a control system. The control system receives actual casting metal temperature data from each thermocouple to control the operation of the adjustable cooling valves.

The disclosed steering wheel and method of manufacturing may include the use of attachment points in the formation of the steering wheel armature. The steering wheel armature can comprise an inner hub, a plurality of spokes, an outer rim, and interface portions connecting the spokes to the outer rim. The method of manufacturing can comprise the steps of providing a mold with upper and lower sections, providing an outer rim, injecting a die cast material into the mold, and removing the outer rim and die cast material assembly.
摘要:
A mold particularly for road vehicle wheels, of the type comprising a lower mold part, an upper mold part and perimetric mold parts that form an impression to be filled with molten material, and comprising a distribution unit that is arranged below the lower mold part and is designed to be connected to at least one riser tube, which is shaped so as to form one or more slots shaped like a circular arc for injecting the molten material into the impression, the slots being arranged, when the mold is closed, at the outer front edge of the impression. The one or more slots are distributed circumferentially so as to allow a balanced injection with respect to the center of the impression.
摘要:
A die particularly for on-road vehicle wheels, of the type that comprises lower, upper and lateral die parts that form an impression to be filled with molten material, comprising at least two die filling points arranged at two openings of the design of a wheel where the lower die part and the upper die part are in contact when the die is in the closed configuration.

A casting mold has a main body provided with a vent hole opened up in a casting space of said main body. The improvement is characterized in that the vent hole is provided with air discharging means and air feeding means which are disposed at the vent hole and the air discharging means and air feeding means are suitably selected so that air within the casting space can be discharged and a pressurized air can be fed toward the casting space through the vent hole.
摘要:
A split mold is closed to define a cavity. The mold has in its lower portion a gate communication with the cavity. A stoke is connected at its upper end to the gate, while its lower end is immersed in a bath of molten metal in a holding furnace. The pressure of the bath is increased, or the pressure of the cavity decreased, whereby the molten metal is introduced into the cavity. The molten metal in the cavity is allowed to solidify to yield a cast product. The product is cooled and removed from the mold. The stoke and the cavity are filled with an inert gas before the molten metal is introduced into the cavity. In order to introduce the molten metal into the cavity, a pressure difference is created between the bath and the cavity at a rate of 0.001 to 0.006 kgf/cm.sup.2 /s. The molten metal is kept at a temperature which is higher than its melting point by 50.degree. to 80.degree. C., or the mold is kept at a temperature of 350.degree. to 430.degree. C. The inert gas is also supplied into the stoke to separate molten metal therein from the solidified product. The surface of the separated molten metal in the stoke is kept above that of the molten metal in the holding furnace when the product is cooled and removed from the mold.
