Abstract
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.
Claims7
A casting mold comprising a fixed mold and a movable mold, and including a cavity formed in a separation surface and configured to mold a product, and a pouring basin and a passageway that are formed in the separation surface and configured to guide molten metal into the cavity,
- the casting mold further comprising a cover member configured to cover an inner wall of a bent portion that is provided in the passageway and is configured to change an advancing direction of the molten metal, the cover member being configured to allow the passageway positioned on an upstream side of the bent portion to communicate with the passageway positioned on a downstream side of the bent portion, and having a lower thermal conductivity than a base material of the casting mold, wherein
- the cover member has a bottomed cylindrical shape having an axis extending in an vertical direction, and includes:
- an upper hole provided at an upper end thereof and opening upward;
- a lateral hole provided on a side wall thereof and opening in a lateral direction;
- and at least one flange provided on the side wall thereof and extending in the vertical direction,
- at least one of the fixed mold and the movable mold includes a flange housing groove in the separation surface, and
- 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 an outer wall of the cover member.
