Abstract
PURPOSE:To make the reutilize of raw materials for mold possible by molding the neighborhood of the part of a mold in contact with molten metal by using ferrous metallic grains. CONSTITUTION:A cope 2 molded in a cope box is formed of a metallic grain layer 7 consisting of binding ferrous metallic grains 5 having about 1mm. diameters with a binder 6 such as water glass for the part from a parting face 3 up to the prescribed height above a cavity 4. The upper part of the layer 7 is formed of a backup sand layer 9 consisting of molding sand. A drag 10 is also constituted of a metallic grain layer 11 and a backup sand layer 12. A mold coating material 15 is coated on the surfaces of the metallic grain layers in the parts of the surfaces of the face 3, the cavity 4, a sprue 13, a runner 14, etc. in contact with molten metal. If molten cast iron is charged into such mold, it is the layers 7, 11 that receive the thermal impact of the molten metal, but the grains 5 will not crack and the mold material is reutilized.
