PURPOSE:To provide the method by simple operation with simple mold for cast molding article having non-parallel planes, which have neither sink mark nor strain. CONSTITUTION:In a mold space, which consists of a pair of plane molding surfaces opposite to each other in parallel having a gasket therebetween, a partition plate mold, which is not parallel to at least one of the plane molding surface and serves for forming one surface of a cast-molded article, is provided. Thus, by the mutual approaching of a pair of the plane molding surfaces and the turning of the partition plate mold, sink mark is prevented from developing. Further, since sealing is easy due to the simple structure of the mold and no leakage of water occurs, strain is also prevented from developing. |
