Abstract: The invention relates to a feeder insert (1, 1?, 1?, 1??, 100, 100?) for use in metal casting in casting molds, comprising a feeder body (2, 2?, 2?, 2??, 102, 102?) which delimits a feeder cavity (4, 4?, 4?, 4??, 104, 104?) for receiving liquid metal, wherein the feeder body (2, 2?, 2?, 2??, 102, 102?) has a first end (6, 6?, 6?, 6??, 106, 106?) having a passage opening (8) for the liquid metal and a second end (10, 10?, 10?, 10??, 110, 110) opposite the first end (6, 6?, 6?, 6??, 106, 106?), and wherein the feeder body (2, 2?, 2?, 2??, 102, 102?) comprises a central axis (Z) extending through the passage opening (8). The feeder body (2, 2?, 2?, 2??, 102, 102?) is separated at least one partition plane (E) extending in a direction of the central axis (Z) and is formed at least from a first feeder shell (18, 18?, 18?, 18??, 118, 118?) and a second feeder shell (20, 20?, 20?, 20??, 120, 120).

Abstract: The invention relates to a method of producing an article selected from the group consisting of casting mold, core, feeder and molding compound for production of part of a casting mold, core or feeder, comprising the following steps: (S1) producing or providing in the foundry: a first component (A), comprising a first binder component (b1) of a binder system and an amount of a first mold base material and, spatially separated therefrom, a second component (B), comprising a second binder component (b2) of the binder system and an amount of a second mold base material wherein the first binder component (b1) and the second binder component (b2) are suitable for chemical reaction with one another and for curing of a mixture of the first component (A) and the second component (B), (S2) mixing by contacting the first component (A) and the second component (B) in a particular mass ratio, so as to result in a self-curing molding compound.

Abstract: The invention relates to a single-part feeder body for use as a feeder insert or component of a two-part or multi-part 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 an inner surface facing toward the feeder cavity, an outer surface for bearing against a mold material that surrounds the feeder body in certain regions, and a passage opening for the liquid metal into the feeder cavity, wherein the feeder wall has, on the inside, one, two or more material recesses for forming one or more outwardly protruding projections on the metal solidifying within the feeder cavity.

Abstract: 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.

Abstract: The invention relates to a method for producing a mold part (26, 26?) with a feeder insert arranged in it, with a sprue for liquid metal, for a divisible casting mold for metal casting, with the following steps: producing or providing a mold part (26, 26?) equipped with a closed feeder insert (2, 2?) from a compacted molding material (28), the closed feeder insert (2, 2?) being arranged fixed in place in the compacted molding material (28) of the mold part (26, 26?) and having a feeder opening (10, 10?) connected to regions of the mold cavity (30, 30?) that is to be formed, and opening the closed feeder insert (2, 2?), so that a sprue (32, 32?) for liquid metal is formed.

Abstract: A use of a feeder insert, having a volumetric center of gravity which is offset in relation to the opening axis of the passage opening of said feeder insert, in the manufacture of a casting mold having a vertical mold separation and a feeder insert which for dense feeding of the mold cavity during the casting procedure is attached to the casting mold, is described, wherein the feeder insert is positioned in a prefabricated mold part of the casting mold such that the opening axis of said feeder insert runs below the volumetric center of gravity of the latter.
