Abstract

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.
