Embodiment Construction

[0018] Depend on figure 1 The visible hopper insert 10 has a hopper body 11 comprising a wall region 13 and a cover region 14 surrounding a cavity 12 which is the interior as a so-called hopper volume. The feeder body has an outer face 16 of the wall region 13 and an inner face 15 surrounding the interior cavity 12 as well as a bottom face 17 in which a feeder opening 18 is formed.

[0019] The feeder insert 10 shown in the "flat" arrangement is to be associated with a vertical mold half 20, for which purpose the feeder insert can be plugged into a not shown structure that is inserted into the mold Attach the molding mandrel at the model. The cling-on mandrel protrudes through the feeder opening 18 in the bottom surface 17 and extends into the cover region 14 of the feeder insert 10, wherein the top end for receiving the cling-on mandrel is formed in this cover region 14 The opening 22. During the overmolding it can be the case that the tip of the overmolding mandrel penetr...

Abstract

A feeder insert (10) for use in a vertically split casting mould that is used for the casting of metals, having 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 mould during production of the casting mould, has a feeder opening (18) for connecting the cavity (12) to the mould cavity of the casting mould, 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), is distinguished by the fact that the feeder body (11) has an uneven mass distribution with respect to the parting plane (25), with a centre 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 centre 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 centre of mass.

Description

technical field [0001] The invention relates to a feeder insert (Speisereinsatz, sometimes called a riser insert) for use in vertically separated molds (Gieöform) used when casting (Gieöen) metals, with There is a feeder body (sometimes called a riser body) made of exothermic and / or insulating material having an interior cavity that acts as the feeder volume (sometimes called a riser volume), the The feeder body has feeder openings (sometimes called riser openings) in its underside facing the model (Modell) which is inserted into the mold when the mold is built, for connecting the cavity with the cavity of the mold. cavity (Formhohlraum) connection, wherein the feeder body is oriented flatly (liegend, sometimes called horizontally) relative to the model with its longitudinal axis extending through the feeder opening at an angle to the vertically oriented model and The volume of the inner cavity is designed asymmetrically with respect to an imaginary parting plane running on o...
