PURPOSE:To reduce a model cost and its managing cost by commonly using split upper and lower molds of a stator frame for the mold of a flanged stator frame, and charging a pair of cores when the frame is cast. CONSTITUTION:A core 4 and a pair of cores 5 for charging substantially lower half port of a casting mold of a pair of mounting legs are manufactured by the models of the cores. Then, upper and lower casting molds are shaped by upper and lower models 2, 3. Then, after the core 4 and the cores 5 are inserted into the lower casting mold, the upper mold is stacked on the lower mold, and the casting frame of the upper and lower molds are rigidly coupled. Then, after a material is filled and naturally cooled, the stator frame is removed from the casting frame, thereby obtaining a flanged stator frame having no mounting legs and formed with a pair of spiral seats. |
