  • Patent number: 11173541
    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.

  • 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.

  • Patent number: 10124401
    Abstract: The invention describes a feeder insert (2, 2?, 2?, 2??, 2IV) for use for the casting of metals in vertically separable casting molds, having a first shaped element (8, 8?, 8?, 8??, 8IV) and a second shaped element (10) which (i) are moveable telescopically relative to one another, (ii) delimit a feeder cavity (30) for receiving liquid metal, and (iii) are designed for being position by means of a centring pin (20, 22?) that can be positioned along a centring axis (28), wherein the first shaped element (8, 8?, 8?, 8??, 8IV) has a passage opening (18) for the liquid metal, and wherein the feeder cavity (30) is designed such that, in the case of horizontal arrangement of the centring axis (28), a predominant volume fraction of the feeder cavity (30) can be positioned above the centring axis.

  • Patent number: 10112235
    Abstract: An arrangement for use in the production of a separable casting mold, preferably of a vertically separable casting mold is disclosed. The arrangement can include (i) a mold plate and/or a mold pattern, (ii) a feeder system having a feeder element and having a feeder insert, wherein feeder element and feeder insert delimit a feeder cavity for receiving liquid metal. The arrangement also includes one or more tipping prevention elements which are designed to counteract tipping of the feeder system out of the opening axis about the first end of the feeder element when, in the event of the feeder system being acted on with a force acting parallel to the opening axis and in the direction of the first end, the side wall deforms and the spacing between the first and second ends is reduced, wherein the one or more tipping prevention element(s) are/is spaced apart from the opening axis.

  • 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).
