PURPOSE: A helical gear molding device is provided to reduce an error rate in a helical gear by controlling a rotating angle of a rotating core and steadily process run-out of a helical gear. CONSTITUTION: A helical gear molding device comprises: a supporting ring(140) which is fixed on a fixed mold(110) at an edge of a cavity; a rotating core(130) which is rotatably installed on a bearing surface of the supporting ring and whose tooth profile(133) is corresponding to a helical gear; an eject pin(150) which ejects the helical gear in the cavity after opening a fixed mold and a movable mold; and a position fixing unit which rotates the rotating core to the original position and fixes the rotating core after the helical gear being ejected by the eject pin.
