Abstract The invention relates to an apparatus for ventilation of a casting mold. ## Claims ### Claim 1 Apparatus (10) for ventilation of a casting mold, particularly in the form of a chill vent, having two mold halves (12, 14) that lie opposite one another and are complementary, in terms of shape and function, to one another, which halves have a plurality of elevations (18) and/or depressions (20), in each instance, which run essentially parallel to one another and essentially transverse to the flow direction, on their surfaces (16) that face one another, in such a manner that when the mold halves (12, 14) are set onto one another, a gap (22) having an inlet (24) and an outlet (26) forms between the mold halves (12, 14), at least in part, which gap can particularly be washboard-shaped, labyrinth-shaped and/or meander-shaped, and through which gap air displaced out of the casting mold and excess molten material can flow during filling of the casting mold, wherein at least one or preferably each mold half (12, 14) is formed by multiple segments (12a, 12b, 12c, 14a, 14b, 14c) disposed next to one another in the longitudinal direction of the mold half (12, 14) and releasably attached, preferably connected with one another. ### Claim 2 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein the segments (12a, 12b, 12c, 14a, 14b, 14c) of the mold half (12, 14), disposed next to one another, have at least one bore (28a, 30), in each instance, for accommodating a fastening means. ### Claim 3 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein at least one, preferably two bores (28a, 28b) that are spaced apart from one another and continuous in the longitudinal direction are provided per segment (12a, 12b, 12c, 14a, 14b, 14c), wherein each bore (28a, 28b) that is continuous in the longitudinal direction aligns with a bore (28a, 28b) of a segment (12a, 12b, 12c, 14a, 14b, 14c) disposed adjacent to it, in such a manner that the segments (12a, 12b, 12c, 14a, 14b, 14c) can be connected with one another, particularly screwed together, by attachment means passed through the aligned bores (28a, 28b). ### Claim 4 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein at least one, preferably multiple bores (30) for attachment means, which are spaced apart from one another and introduced from the outside, on one side, in the transverse direction, are provided per segment (12a, 12b, 12c, 14a, 14b, 14c), by means of which each segment (12a, 12b, 12c, 14a, 14b, 14c) can be connected with a base body, particularly the casting mold, particularly screwed onto it, preferably in such a manner that the segments (12a, 12b, 12c, 14a, 14b, 14c) are releasably disposed next to one another in the longitudinal direction of the mold half (12, 14). ### Claim 5 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein the segments (12a, 12b, 12c, 14a, 14b, 14c) of the mold half (12, 14) can be releasably connected with one another with shape fit and/or force fit. ### Claim 6 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein the segments (12a, 12b, 12c, 14a, 14b, 14c) of a mold half (12, 14) consist of the same material, preferably of steel. ### Claim 7 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein the segments (12a, 12b, 12c, 14a, 14b, 14c) of a mold half (12, 14) consist of a different material, preferably of steel, copper, tungsten or a molybdenum alloy. ### Claim 8 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein at least two segments (12a, 12b, 12c, 14a, 14b, 14c) of the mold half (12, 14) are configured with an identical shape. ### Claim 9 (depends on 3) Apparatus (10) for ventilation of a casting mold, according to claim 3, wherein the bores (28a, 28b) that align with one another can be used as a coolant line, particularly for air or water. ### Claim 10 (depends on 1) Apparatus (10) for ventilation of a casting mold, according to claim 1, wherein the two mold halves that lie opposite one another and are complementary, in terms of shape and function, to one another, have a plurality of steps, in each instance, which run essentially parallel to one another and essentially transverse to the flow direction, on their surfaces that face one another, in such a manner that when the mold halves are set onto one another, the steps of one mold half form a stair-shaped gap having an inlet and an outlet with the steps of the second mold half, through which gap air displaced out of the casting mold and excess molten material can flow during filling of the casting mold.
