Abstract:
1. A device for the manufacture of casting molds, comprising a base, a pressing cylinder, a molding table, a filling frame, a pattern plate with patterns, a pulsed-air head mounted above the molding table and linked to a compressed air supply system, a movable latticed pressing element mounted in the lower part of the pulsed-air head with the use of an elastic fixture, and a mechanism for filling with mold-sand the filling frame and the casting box, in which the filling frame is built-in into the molding table and is made with the possibility to place on it molded casting boxes and to take them away, the pattern plate with the patterns being mounted with the possibility of a reciprocal motion in the cavity of the filling frame, and the pressing cylinder is mounted with the possibility to apply a force to the movable pattern plate, the device being additionally provided with one cylinder or with a system of interrelated cylinders fixing the latticed pressing element in the low position and linked to pressure sources located on a traverse in the way to enable their extended rods to apply a force to the pressing element elastically mounted on the traverse for providing a counter-pressure force.
