An apparatus for molding a hairpin inserted into a stator core includes a clamping unit including a connection bracket mounted on a front end of a robot arm and at least one clamper mounted on the connection bracket and configured to be reciprocally driven in opposite directions in a straight line, and a mold unit detachably coupled with the at least one clamper and configured to press mold a head portion of the hairpin by a molding jig configured to be driven by the at least one clamper.

A method can be used for inserting a hairpin in a stator core. The method includes unwinding a coil spiral-wound on an uncoiler, forming a decoated portion by decoating a predetermined portion on the coil, bending the coil in multiple stages to two-dimensionally form a leg portion and a head portion of a hairpin, cutting the coil formed with the leg portion and the head portion by a predetermined length, and moving the hairpin to be inserted into a stator core while three-dimensionally forming the head portion.
