  • Patent number: 11130169
    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.
    Type: Grant

  • Patent number: 9987676
    Abstract: A feeder insert for use for the casting of metals into casting molds, having a mold body (6) and a supply element (4) which delimit the feeder cavity (10) for receiving liquid metal, wherein the supply element (4) has a passage opening (26) for the liquid metal, and wherein the mold body (6) is movable in a feeder longitudinal direction relative to at least one part of the supply element (4), characterized in that the supply element (4) has a deformation region which is designed to trim in at least in sections in at least a first phase of a relative movement of the mold body (6) in the feeder longitudinal direction and in the direction of the supply element (4).
