The present invention relates to a method for casting of cast parts in which molten metal is poured via a feeder, separate runners, or casting channels into a mould cavity defined by a casting mould and modeling the shape of the cast part, whereby the casting mould includes mould parts which determine the shape of the cast part to be cast. Molten metal is conveyed via at least two connections into at least two sections of the mould cavity which correspond to different planes of the part to be cast. At least one of the connections is designed as an additional channel leading through one of the mould parts and independent of the contour of the cast part to be cast. The present invention also relates to a casting mould as described above.

When a mold for a tire is manufactured by casting, generation of a casting defect for the casting of the mold is easily suppressed so that the manufacturing efficiency of the mold is improved. The mold molds a tire by molding parts arranged along a tire width direction. A width direction of a casting of the mold corresponding to the tire width direction is matched with a vertical direction. A riser is connected to a part of the rear-face part of the casting located on the rear-face side of the molding part. A chiller is arranged on a part other than the riser of the rear-face part of the casting.

A casting method using combined 3D printed shell mold and the combined shell mold used in the method. The method consists of shell mold making and casting steps. The shell mold is constructed by combination. First, the 3D printer at least prints out a runner part and several pattern die parts for molding products. In the print run, the first interfaces corresponding to the quantity of pattern die parts are printed out integrally on the runner part. The second interfaces corresponding to the first interfaces are formed on the pattern die parts. Afterwards, the first interfaces and the second interfaces are butted, the primary runner in runner part is connected to the die cavities in pattern die parts, the runner part and pattern die parts are combined to form a shell mold for casting multiple products at a time.

A low-pressure casting mold includes at least upper and lower molds 4U, 4L forming a cavity 3 and sprue pieces 8, 9 that have cylindrical shapes and that are disposed at different positions of the lower mold 4L. The sprue pieces 8, 9 include sprues 8A, 9A open to the cavity 3 and basins 8B, 9B, and the basins 8B, 9B have different volumes according to the position of the sprue pieces in the lower mold 4. Equalization of the solidification time of molten metal at the sprues 8A, 9A is achieved along with the less influence on the structure of the lower mold 4L and a stalk and the improved flexibility in apparatus design.

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 cm.sup.3.

A hot runner feed system is provided for a diecasting mold, wherein the feed system has a melt manifold and feed block construction having an entry-side feed inflow opening, at least one first and one second exit-side feed outflow opening which open into a mold separation plane between a fixed mold half and a movable mold half of the diecasting mold, and a casting runner-duct structure that extends so as to branch out from the feed inflow opening to the feed outflow openings. The melt manifold and feed block construction at least in an exit-side block region that includes the two feed outflow openings in a transverse direction parallel with the mold separation plane in relation to a predefined nominal operating extent is made so as to be shortened by an expansion dimension which has been predefined as a thermal transverse expansion of this block region when heated from a room temperature range to a predefined operating temperature range that is elevated in relation to said room temperature range.

A cluster model and a shell for the production, by lost wax casting, of a plurality of turbomachine elements, are provided. The shell includes a central sprue that is fluidly connected to a casting cup for receiving molten metal; a plurality of shell elements; a plurality of bottom feed conduits for the shell elements; and a handling accessory shell that is independent of the plurality of shell elements and of their metal supply circuit, such that there is no fluid connection to the shell elements. The handling accessory shell is fluidly connected to the central sprue so as to allow top-pour casting of the handling accessory shell.

A deterioration determining apparatus includes: an operating condition acquirer to acquire an operating condition of a processing device; a processing state data acquirer to acquire processing state data detected by a sensor attached to the processing device; a learning model generator to conduct machine learning using, as learning data, the operating condition and the processing state data so as to preliminarily generate a learning model concerning the operating condition and the processing state data; an actual data acquirer to acquire actual data that is the processing state data at a determining time; a predicted data acquirer to acquire, using the learning model, predicted data that is the processing state data for the operating condition at the determining time; and a determiner to determine the degree of deterioration in the processing device in accordance with the degree of divergence between the actual data and the predicted data.

Example systems include a vacuum chamber enclosing a pouring cup and a platform configured to support a casting assembly. The casting assembly is configured to hold a plurality of joinable components and a mold defining at least one mating groove configured to join at least two joinable components of the plurality of joinable components when occupied with a metal or an alloy. Each respective mating groove is fluidically connected to a respective surface opening of a plurality of surface openings defined by the mold. The pouring cup and the respective surface opening are movable relative to each other by moving at least one of the pouring cup or the platform supporting the casting assembly to substantially align the pouring cup with the respective surface opening. The pouring cup is configured to pour a respective volume of molten metal or alloy in at least two surface openings.

A feed system for conveying a molten metal that is to make a casting, the system including a feed channel made of ceramic material that is configured to enable the molten metal to flow by gravity inside the feed channel, the feed channel having a first portion extending in a first direction, and at least one second portion extending in a second direction different from the first direction, the second portion being arranged downstream from the first portion and being connected to the first portion by a junction.
