The inner mold is formed to include an oil path from an interface of the first and second molds to an edge of the first mold. The upper mold is coupled with the first attachment surface and includes a core insertion hole(230) for extending the oil path to an edge of the core. The lower mold includes an oil path forming hole(330), for extending the oil path to a lower edge of the second mold, and a mold ejecting hole(320) coupled with the oil path forming hole.
