An insert (cover member) is formed of an iron-based alloy. A casting mold is constituted by a fixed mold and a movable mold. An insert housing portion (cover housing portion) for housing the insert is formed in a separation surface between the fixed mold and the movable mold, and a magnet is embedded in the insert housing portion of either the fixed mold or the movable mold. A robot grips the insert with a gripping portion (hand) to convey the insert to a position facing the insert housing portion, releases the insert at the facing position in a state where a predetermined clearance is secured between the insert and the insert housing portion, and causes the insert to be attracted to the insert housing portion by the magnet.

Insert mounting device

A casting mold includes a cavity for molding a product, and a pouring basin and a passageway that guide molten metal into the cavity. The passageway includes, at portions thereof positioned below the pouring basin and the cavity, bent portions (a first bent portion, a second bent portion) that change the advancing direction of the molten metal, and the casting mold further includes a cover member, which covers the inner wall of the bent portion, allows the passageway positioned on the upstream side of the bent portion to communicate with the passageway positioned on the downstream side of the bent portion, and has a lower thermal conductivity than the base material of the mold.

Casting mold

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.
