<P>PROBLEM TO BE SOLVED: To surely perform the removal of burrs in a casting apparatus and a casting method. Ž<P>SOLUTION: A recessed part 14b is formed at the tip-end part 14a of a passage-forming part 14 in a movable mold 4 and also, a projecting part 16b for fitting into the recessed part 14b is formed at the tip-end part 16a of a sliding part 16 in a slid core 6, and since fitting face between the passage-forming part 14 in the movable mold 4 and the sliding part 16 in the slide core 6, is formed of the plurality of faces, molten metal 10' is difficult to flow into the fitting face and a continued large burr 12 is difficult to form in a bending passage 8. Even if the continued large burr 12 is formed onto the fitting face of the passage part 14 in the movable mold 4 and the sliding part 16 in the slide core 6, when a product 20 is taken out from the movable mold 4, a large part of the burr 12 formed on the fitting face with the recessed part 14b can be removed. In this result, since the large burr 12, such burr 12 as catching in the bending passage 8, is not remained, the removal of the burrs can surely be performed. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
