Method for manufacturing laminated iron core

A method for manufacturing a laminated iron core is provided. A laminated iron core body including a permanent magnet inserted into a magnet-insert hole is arranged between a molding die and a holding die. A cull plate is arranged between the molding die and the laminated iron core body. The cull plate has a groove shaped runner directed toward the magnet-insert hole from a resin reservoir and provided with a gate hole communicating with the magnet-insert hole, and a through hole which vertically passes through the cull plate is formed in the runner of the cull plate at a different position from a position of the gate hole. After the magnet-insert hole is filled with the mold resin a resin residue remaining in the cull plate is pushed off and removed from the gate hole and the through hole.
