A mold assembly for use in forming a component having an outer wall of a predetermined thickness includes a mold and a jacketed core. The jacketed core includes a jacket that includes a first jacket outer wall coupled against an interior wall of the mold, a second jacket outer wall positioned interiorly from the first jacket outer wall, and at least one jacketed cavity defined therebetween. The at least one jacketed cavity is configured to receive a molten component material therein. The jacketed core also includes a core positioned interiorly from the second jacket outer wall. The core includes a perimeter coupled against the second jacket outer wall. The jacket separates the perimeter from the interior wall by the predetermined thickness, such that the outer wall is formable between the perimeter and the interior wall.

A method for casting an article comprises a first region and a second region. The method comprises casting an alloy in a shell, the shell having a casting core protruding from a first metal piece; and deshelling and decoring to remove the shell and core and leave the first region formed by the first piece and the second region formed by the casted alloy.

A device and a method are provided for measuring the moisture in die cast molds, the cavity of which is connected via an evacuation conduit to an evacuation device. The modular assembly of the device is connectable to the evacuation conduit and includes a sensor assembly to measure the moisture of gases evacuated from the mold cavity. The sensor assembly includes an emitter emitting electromagnetic radiation and a detector detecting electromagnetic radiation. On the basis of the measured values obtained during the evacuation action it can be determined whether the amount of a water/release agent mixture jetted into the mold cavity needs to be altered before the actual casting action.

A ventilator for a casting mold is mounted on an exhaust pipe (11) of a mold (10) to emit gas generated when melt is injected into a molding space (12). The ventilator for a casting mold has exhaust holes which are improved in arrangement structure and are shorter than a cylindrical body part so as to enhance gas emission efficiency and prevent transformation of the exhaust holes, and has a buffering space part formed inside a cylindrical body part to spread and accept melt coming through the exhaust holes so as to effectively prevent a damage of a mold caused by external leakage of the melt. The ventilator for the casting mold includes a cylindrical body part (100) and a fixed type exhaust block (20).

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.

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.
