An apparatus for ventilation of a casting mold has two mold halves that lie opposite one another and are complementary, in terms of shape and function, to one another. The halves have a plurality of elevations and/or depressions, in each instance, which run essentially parallel to one another and essentially transverse to a flow direction, on their surfaces that face one another, in such a manner that when the mold halves are set onto one another, a gap having an inlet and an outlet forms between the mold halves, at least in part. The gap is washboard-shaped, labyrinth-shaped and/or meander-shaped. Through the gap, air displaced out of the casting mold and excess molten material flow during filling of the casting mold. At least one mold half is formed by multiple segments disposed next to one another in the longitudinal direction of the mold half and releasably attached. |

1. An apparatus for ventilation of a casting mold, the apparatus being in the form of a chill vent, having two mold halves that lie opposite one another and are complementary, in terms of shape and function, to one another, which halves have a plurality of elevations and/or depressions, in each instance, which run essentially parallel to one another and essentially transverse to a flow direction, on their surfaces that face one another, in such a manner that when the mold halves are set onto one another, a gap having an inlet and an outlet forms between the mold halves, at least in part, which gap is washboard-shaped, labyrinth-shaped and/or meander-shaped, and through which gap air displaced out of the casting mold and excess molten material flow during filling of the casting mold, wherein at least one mold half is formed by multiple segments disposed next to one another only in the longitudinal direction of the mold half, releasably attached, and having a same height in the transverse direction, wherein at least two bores that are spaced apart from one another and continuous in the longitudinal direction are provided per segment, and wherein each bore that is continuous in the longitudinal direction aligns with a bore of a segment disposed adjacent to it, in such a manner that the segments are connected with one another via an attachment element passed through the aligned bores. |
