る。SUMMARY OF THE INVENTION In order to achieve this object, a vehicle wheel molding apparatus according to the present invention includes a vehicle wheel molding apparatus in which a disk portion is offset toward a front rim flange. The mold for casting the outer surface of the rim is divided into a rim back side forming member forming the front side bead seat portion to the back side flange portion and a rim front side forming member forming the front side bead seat portion to the front side flange portion, and Since the volume of the rim front side forming member is larger than the volume of the rim rear side forming member, the molten metal portion that contacts the rim front side forming member is more easily cooled than the molten metal portion that contacts the rim rear side forming member, that is,
As a result, the continuous portion of the vehicle wheel between the rim portion and the disk portion is cooled more easily than the other portions of the rim portion, so that the thick continuous portion can be prevented from being cast rot.

るものである。Since the volume of the rim front side forming member 70 is larger than the volume of the rim rear side forming member 80, the portion cast by the rim front side forming member 70 is faster than the portion cast by the rim rear side forming member 80. It can be cooled down. Further, even if the cavity surface (the molten metal contact surface) of the rim front side forming member 70 is smaller than the cavity surface (the molten metal contact surface) of the rim back side forming member 80, the portion cast by the rim front side forming member 70 may be reduced. Since the heat absorption is greater than the part cast by the rim back side forming member 80, the rim can be cooled quickly.

できるものである。The molten metal portion in contact with the rim front side forming portion is easier to cool than the molten metal portion in contact with the rim back side forming portion. That is, the continuous portion between the rim portion and the disk portion of the vehicle wheel is formed by the rim portion. As a result of being easier to cool than the other portions, the thick continuous wall portion can be prevented from being cast rot.
