The base mold has a first cavity(24) for forming the body unit and the protruded unit. A second cavity(34) for forming a part of the body unit and the protruded unit is formed by combining the upper mold and the base mold. The first and second forging molds are installed at both sides of the upper mold. The first and second forging molds have a third cavity(43) to forge the protruded unit. The guide unit guides the upper mold and the first and second forging molds about the base mold.
