CONSTITUTION: Manufacturing apparatus comprises a guide hole(12) in a base(10) which has a shape corresponding with a circumference part of upper inlet of a casting mold. On the upper side, a flame is installed to surround a through hole(22). A projection part for molding(22) is formed in a shape corresponding to a cavity, and projected upward from the base through the guide hole of the base.
