  • Patent number: 11318531
    Abstract: A gate valve system includes a base plate and a gate valve plate, a casting plant includes the gate valve system, and a casting process manufactures workpieces, particularly from metal materials. The base plate has an opening and the gate valve plate has a first opening and at least a second opening. The separating gate valve system is set up so that the separating gate valve system can be brought into casting, pressing, and closure positions. In the casting position, the first opening is arranged to align with the opening of the base plate, at least to the greatest possible extent; in the pressing position, the second opening is arranged to align with the opening of the base plate, at least to the greatest possible extent; and in the closure position, the gate valve plate closes off the opening of the base plate.
    Type: Grant

  • Patent number: 10596620
    Abstract: A mold for production of cast parts, having two mold parts in the form of mold plates, which mold parts arc movable with respect to each other from an open position into a closed position, wherein the mold parts in their closed position define a mold cavity which may be filled with liquid casting compound and in their open position enable removal of a cast part which has solidified by at least partial cooling, and are lockable in their closed position by a locking device which joining the two mold parts so as to be releasable, and which mold parts may also be swung, wherewith in the closed position the locking device produces the locking of the mold plates with the stipulation that the locking pressure is maintained. The locking device has an energy storage means with a gas pressure spring for maintaining the closing pressure which presses the mold plates together after they have initially been pressed together.
