摘要： PROBLEM TO BE SOLVED: To provide a casting method by which a cylinder block, the upper part of crankcase and the upper part of transmission case can integrally be cast at high precision. SOLUTION: This casting method is performed as follows. A metallic mold 1 is set so as to make the cylinder block 21 side direct to the lower side, the upper part of the crankcase 22 side direct to the upper side and a crankcase mating surface 24 direct upward, and molten metal is poured into the metallic mold 1 by the own weight of the molten metal in molten metal pool 15 arranged at the reverse side of the transmission case side of the upper part of the crankcase 22. This molten metal is filled into the cylinder block 21 from the upper part of the crankcase 22 and also, after filling the molten metal into the upper part of the transmission case 23, the molten metal in the molten metal pool 15 of the upper part of the crankcase 22 is utilized as a feeder head, and thus, the cylinder block 21, the upper part of the crankcase 22 and the upper part of the transmission case 23 are integrally cast by gravity casting.

解决方案：该铸造方法如下进行。金属模具1被设定为使气缸体21侧直接向下侧，曲轴箱22侧的上部直接向上侧，曲轴箱配合面24向上方引导，将熔融金属倒入金属模具1通过设置在曲轴箱22的上部的变速箱侧的相反侧的熔融金属池15中的熔融金属的重量。该熔融金属从上部部分填充到气缸体21中曲轴箱22，并且在将熔融金属填充到变速箱23的上部之后，曲轴箱22的上部的熔融金属池15中的熔融金属被用作给料头，因此，缸块21，曲轴箱22的上部和变速箱23的上部通过重力铸造整体铸造。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To mold a wheel for a vehicle with high quality having no blowhole by pressure casting with high productivity even when the cross sectional area of a connection part for connecting an outer circumferential rim with the hub of a central part is small.
SOLUTION: When casting the wheel for the vehicle having the hub 21 of the central part, the rim 22 of an outer circumferential part and the connection part 23 for connecting the hub 21 with the rim 22, a cavity 8 for molding the wheel in a posture which makes a wheel axis C almost horizontal is formed inside a molding die 1 that opens/closes in an almost horizontal direction. A molten metal 4 is pressurized and injected into the lowermost part 8d of a rim forming part 8a in the cavity 8, a pushing-in pin 7 is advanced from an axial direction to the central part of a hub forming part 8c in the cavity 8 at the midway of the solidification of the molten metal 4, and the solidification of the molten metal 4 is completed in such a state.
