The present invention is related to a method for centering a pouring tube in a pouring tube assembly using a multi-piece centering sleeve by inserting a pouring tube into a holding casting aperture in a holding casting; pouring grout to fill a portion of a gap between the pouring tube and the holding casting; slipping the centering sleeve over the outside of the pouring tube until it is press fit in a portion of the gap between the pouring tube and the holding casting; adjusting the centering sleeve to center-position the pouring tube; grouting the remainder of the gap to fill all voids in the gap; installing a parting ring on top of the holding casting; and installing a holding ring around the holding casting and parting ring.

The present disclosure relates to a tilt casting mold, a tilt casting apparatus, and a tilt casting method that can manufacture a molded product with a small quality difference without compensation for contraction of molten metal by forming a riser on a tilt casing mold and pressing the riser. According to an embodiment, there is provided a tilt casting mold that includes a cope and a drag, in which when the cope and the drag are combined, a predetermined cavity is formed therein and a riser is formed on a side of the cavity; a pouring cup is coupled to a surface having the riser of the drag; molten material is poured in the pouring cup and then the molten metal in the pouring cup is injected into the cavity by tilting the mold assembly composed of the cope, the drag, and the pouring cup.

A counter gravity casting apparatus includes a reusable metal mold having a plurality of mold cavities, a feed tube configured to feed molten alloy into the mold, and a vacuum fitting configured to permit a vacuum to be applied to the mold. The mold includes multiple metal sections configured such that adjacent metal sections mate to one another, the metal sections being separable from one another. The metal sections include recesses that form the mold cavities, and the mold includes a sprue and multiple runner passages. The sprue is configured to receive molten alloy from the feed tube, and the multiple runner passages are configured to feed molten alloy from the sprue to the mold cavities. Methods of casting bulk amorphous alloy articles or feedstock is described.

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.
