Abstract:
A device for regulating the evacuation of air and gas from a casting die, the device comprising:a first body having an internal static surface; a second body with a moveable element having a front moveable surface, said first and second bodies being two complementary bodies positioned face to face one on top of another to form a wavy shaped substantially horizontally extending evacuation channel arranged between said first body and said second body with an inlet end and an outlet end, said two complementary bodies being connectable at said inlet end to a die and said two complementary bodies being connectable at said outlet end to a vacuum device, said evacuation channel being delimited by said internal static surface of said first body and by a front vertically movable surface of said movable element, said front vertically movable surface being arranged in front of and in parallel to said static surface and being movable perpendicular to said static surface to vertically adjust the section of said evacuation channel; and a wedge-shaped positioning member and guides, wherein said movable element is arranged in a cavity of said second body and is joined to said wedge-shaped positioning member, which is guided in said second body and can be longitudinally moved in a plane that is parallel to a plane in which said evacuation channel lies, said movable element and said positioning member being coupled via said guides which are sloped with respect to the plane in which said evacuation channel lies such that a vertical movement of said movable element above the static surface of the channel corresponds to each longitudinal movement of said positioning member.
