Abstract

An apparatus includes a mold unit and a receive unit which clamp a laminated iron core body from both sides in a lamination direction, the laminated iron core body including a plurality of laminated iron core pieces and a resin hole pierced in the lamination direction, a plunger which extrudes a resin of an inside of a resin pool part formed in the mold unit, and a cull plate arranged between the laminated iron core body and the mold unit. The cull plate includes a close contact part with the resin on a side opposed to the plunger, the close contact part including a projection projected to a side of the plunger beyond a groove bottom of a runner formed in the cull plate, or a recess recessed to a side of the laminated iron core body beyond the groove bottom of the runner.
