Feeder Insert For A Vertically Split Casting Mold
A feeder insert (10) for use in a vertically split casting mold that is used for the casting of metals includes a feeder body (11), which has an internal cavity (12) as feeder volume and which is composed of an exothermic and/or insulating material and which, in the base surface (17) thereof, which faces toward a pattern inserted into the casting mold during production of the casting mold, has a feeder opening (18) for connecting the cavity (12) to the mold cavity of the casting mold, wherein the feeder body (11) is oriented with its longitudinal axis (21), which runs through the feeder opening (18), at an angle with respect to the vertically oriented pattern and so as to be horizontal relative to the pattern, and the volume of the internal cavity (12) is of asymmetrical design with respect to an imaginary parting plane (25) running in or parallel to the longitudinal axis (21), characterized in that the feeder body (11) has an uneven mass distribution with respect to the parting plane (25), with a center of mass situated to one side of and spaced apart from the parting plane (25), and that region (28) of the internal cavity (12) of the feeder body (11) which is situated on that side of the parting plane (25) which is situated opposite the center of mass has a larger volume than that region (29) of the internal cavity (12) which is situated on that side of the parting plane (25) which faces toward the center of the mass.
Single-piece feeder body for use in metal casting
The invention relates to a single-piece feeder body for use as a component of a two-part or multi-part telescopic feeder insert in metal casting, having a feeder wall which at least partially delimits a feeder cavity for receiving liquid metal, wherein the feeder wall has a passage opening for the liquid metal into the feeder cavity, and an outer surface on which there are arranged at least one outwardly projecting holding element and at least one guide part with a sliding section for a feeder element which corresponds with the feeder body,
wherein the guide part has a supporting section which protrudes outwardly on the outer surface and which, adjoining the sliding section of the guide part for guiding the feeder element, extends in the direction of the passage opening.
Riser
The invention relates to a molding riser for casting metals, wherein the riser has a metal riser body. The invention also relates to the use of the riser for casting metals into separable casting molds, in particular horizontally separable casting molds.
Casting Mold and Method for Producing a Casting
A casting mould for producing a casting formed from a light metal alloy, in particular a housing for an electric drive for a motor vehicle. The casting mould advantageously has at least one sand core which is designed and arranged in the casting mould in such a way that the at least at least one sand core can be completely surrounded, at least in sections, in a circumferential direction by a light metal melt with which the casting mould is filled to form the casting. It is advantageous to be able to produce a casting in which, for example, a cooling channel is incorporated. It is not necessary to drill a hole to form a channel. Furthermore, the invention relates to a process for manufacturing a casting made of a light metal alloy, in particular a housing for an electric drive for a motor vehicle.

APPARATUS AND PROCESS FOR CASTING METAL PARTS
An improved apparatus for casting metal parts. The apparatus is contemplated as including at least one mold cavity formed by at least one at least partly surrounding cavity wall, a system of sprues, runners and/or ingates defining at least one flow channel for filling the at least one mold cavity with molten metal, at least one riser insert arranged at least partly inside at least one riser cavity of at least one riser. The at least one riser insert comprises at least one insert cavity for receiving molten metal at least partially from the at least one mold cavity and at least one the insert cavity at least partly surrounding riser insert wall, wherein the at least one riser insert is configured to at least partly decelerate the solidification of the molten metal received by the at least one insert cavity.
