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.
Claims20
A single-part feeder body (1) for use as a feeder insert or component of a two-part or multi-part feeder insert (30) in metal casting, having a feeder wall (2) which at least partially delimits a feeder cavity (10) for receiving liquid metal, wherein the feeder wall (2) has
- an inner surface (3) facing toward the feeder cavity (10),
- an outer surface (4) for bearing against a mold material that surrounds the feeder body (1) in certain regions,
- and
- a passage opening (8) for the liquid metal into the feeder cavity (10),
- wherein the feeder wall (2) has, on the inside, at least one material recess (12) for forming at least one outwardly protruding projection, respectively, on the metal solidifying within the feeder cavity (10), wherein the material recess (12) is designed such that metal solidifying in the feeder cavity (10) forms an undercut.
