<P>PROBLEM TO BE SOLVED: To provide a mold for vehicle wheels in which the occurrence of pin holes in the vehicle wheel can be restrained, the metalographic structure can be made fine and the projection formed by solidification of molten metal in a runner is easily removed. <P>SOLUTION: The mold 10 is provided with a lower mold 12, an upper mold 13 and the plurality of side molds 14, and when the molds are fastened, a space 21 for forming a disk part and a space 22 for forming rim parts, are formed. The runners 26 are formed among mating surfaces of the plurality of side molds 14. Each runner 26 has a main passage 26a and two divided passages 26b, 26c divided from this main passage and the tip ends of these divided passages 26b, 26c are provided as side gate parts 26x, 26y separated in the vertical direction and connected with the space 22 for forming the rim part. The vehicle wheel is cast by filling up the molten metal into a cavity 20 for forming from the runner 26. The projection formed with the solidification of the molten metal in the runner 26, is removed from the vehicle wheel after casting. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
