Method of force-fitting separate member into casting and apparatus therefor

摘要

A cavity defined by a casting mold is filled with a molten metal in such a condition that a sliding member movable forward and rearward has been moved into the cavity. The sliding member is drawn out of the cavity when the molten metal solidifies to such a degree as to maintain a certain shape. A separate member to be force-fitted is placed between the distal end of the sliding member and the cavity. The sliding member is then advanced into the cavity so that the separate member is force-fitted into a concave portion formed in the casting before the casting mold enclosing the casting is opened. The separate member is thus force-fitted into the casting while the casting is enclosed in the casting mold.
