ABSTRACT:
A molding apparatus for molding a coil of a stator of a rotary electric machine having a novel construction for fitting the stator readily to its mold enabling the molding operation to be continuously performed without interruption even if the thickness of the stator shows variations when fitted to the mold. The molding apparatus includes a pair of mold members, one mold member enclosing one coil end of the stator having a stator core and a coil wound thereon with a clearance therebetween and positioned against one end surface of the stator core disposed outwardly of the one coil end and the other mold member set on the inner periphery of the stator core and enclosing the other coil end of the stator with a clearance therebetween while being positioned against the other end surface of the stator core disposed outwardly of the other coil end. The two mold members are prevented from striking each other when the stator core is held therebetween. A plurality of runners are formed on the other mold member for communicating a first space formed between the first mold member and the one coil end with a second space formed between the second mold member and the other coil end.
