Abstract

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.
