RESIN FILLING DEVICE OF ROTOR FOR ROTARY ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide a resin filling device capable of easily positioning a lamination iron core in its radial direction with respect to a resin injection mold, and filling a clearance between a magnet insertion hole and a magnet with resin uniformly as much as possible.SOLUTION: A resin filling device 1 fills clearances 42 formed between magnet insertion holes 41 and permanent magnets 5 when the permanent magnets 5 are arranged in the plurality of magnet insertion holes 41 arranged side by side in the circumferential direction of a lamination iron core 4 of a rotor, respectively, with a resin 6. The resin filling device 1 comprises: a resin injection die 2 having injection ports 21 for injecting the resin 6 into the clearances 42 opened to a contact surface 201 contacting one end surface 401 of the lamination iron core 4; and a counter die 3 for contacting the other end surface 402 of the lamination iron core 4 and sandwiching the lamination iron core 4 with the resin injection die 2 to press the lamination iron core 4. A projection 22 projecting from the contact surface 201 of the resin injection die 2 is formed around an opening 211 of the injection port 21. The projection 22 is arranged at an inner peripheral end of the magnet insertion hole 41.
