A device for regulating the evacuation of air and gas from a casting die. It comprises two complementary bodies (11, 12), which can be closed, face to face, one on top of another, and which delimit an evacuation channel (13). The evacuation channel (13) is defined by a static surface (16) of the first of the bodies (12) and by a movable surface (18) that is arranged in front of and in parallel to the static surface (16) and that consists of the front surface of a movable element (17). The movable element (17) is arranged in the second of the bodies (11) and can be moved at right angles to the static surface (16) in order to vertically adjust the section of the evacuation channel.
