Abstract

PURPOSE: To readily mold the composite mold which is molded with sand molds in the fixed positions of upper and lower metal molds by combining the upper and lower metal molds and blowing metal molds and blowing and packing resin sand to the entire part of the well, sprue and sprue base and a part of casting mold.
CONSTITUTION: The upper mold 1 and lower mold 2 formed with cavities 3, 4 to beome crankshaft or the like, well and head parts 5, sprue 6, sprue button 7 and molten metal part 8 are respectively combined with blowing metal molds 11, 12. These are passed through a preheating furnace to be preheated and a fixed amount of resin sand is blown and packed into the respective cavities 5', 6', 9 and 7', 10' of the upper and lower molds 1, 2. When the resin sand sets, the blowing metal dies 11, 12 are removed. This yields the metal molds 1, 2 molded with sand molds in the fixed positions. This composite mold may be readily volume-produced, and its head and well are reduced, thus the moldings free from defects such as cavities and crackings may be obtained with a good yield.
