Vibrating machine for producing molded bodies by means of compacting

A vibrating machine for producing a molded body by compacting a granular raw mixture, comprising:

• a vibrating table mounted on springs so as to be oscillatable, the vibrating table being configured to receive a molding box fillable with the raw material;
• a cover weight configured to be introduced into the molding box once the molding box has been filled with the raw material;
• and
• a clamping device produced by at least two clamping closures configured to clamp the molding box to the vibrating table and disposed at respective sides outside the molding box, each of the clamping closures comprising:
• a pivot bracket having a lower end and an upper end, the lower end being pivotally mounted on the vibrating table and the upper end including a cranking which is directed outward and faces away from the molding box;
• a double-acting hydraulic pivot cylinder pivotally mounted on the vibrating table;
• a two-armed rocker arm pivotally connected, at a spacing below the cranking, to the pivot bracket, the rocker arm including an inner part that cooperates with the molding box and an outer part that cooperates with a piston rod of the hydraulic pivot cylinder;
• and
• a compression spring disposed in the spacing between the cranking of the pivot bracket and a top side of the outer part of the rocker arm such that the compression spring releases the rocker arm from a position closing the respective clamping closure upon a pressure in the hydraulic pivot cylinder being relieved.
