摘要： A casting mold includes a cover member covering the inner wall of a bent portion (a first bent portion, etc.) of a passageway. The cover member has a bottomed cylindrical shape having an axis extending in an up-down direction, and includes an upper hole, lateral holes, and at least one flange (a side wall flange). At least one of a fixed mold and a movable mold includes a flange housing groove in a separation surface. When the cover member is disposed in the bent portion and the casting mold is closed, the flange is housed in the flange housing groove, and the cover member is held in a state where a gap is formed between the inner wall of the bent portion and the outer wall of the cover member.

摘要： Disclosed herein is a casting cluster for casting a body of a golf club head made of titanium or a titanium alloy. The casting cluster comprises a receptor and a plurality of runners coupled to the receptor and configured to receive molten metal from the receptor. The casting cluster also includes at least twenty-eight main gates. At least two of the main gates are coupled to each of the runners and each main gate is configured to receive molten metal from a corresponding one of the plurality of runners. The casting cluster further comprises at least twenty-eight molds. Each mold of the at least twenty-eight molds is configured to receive molten metal from a corresponding one of the main gates and to cast a body of a golf club head that has a volume of at least 100 cm3.
