Vibration casting station with swing-in mold clamping hooks

Claim 1

A casting station in an installation for making concrete components comprising a foundation frame including brackets provided with shock absorbers and supporting a plurality of transverse vibration beams whose lower surfaces are connected to at least one vibrator for producing vertical vibrations and whose upper surfaces form a support for a mold adapted to be conveyed from a preceding station over the vibration beams, said mold having protruding part side walls hinged at their bottom and adapted to be held in a locked upright position during the concrete casting operation by means of a plurality of clamping devices, said clamping devices being provided at either end of each vibration beam and each having a substantially U-shaped clamping hook whose lower end is pivotally mounted in a pressure head at the end of a piston rod of a power cylinder which is fastened to the ends of the vibration beam, and a guide and pressure means mounted opposite the body portion of each clamping hook on the foundation of the casting station and adapted to guide said hook when the latter is lifted by the power cylinder from a lower swungout position to an upper swung-in position wherein pressure side wall holding means on the hook is brought into position over the protruding part of a side wall by actuation of the power cylinder and said holding means is adapted to be pressed down against said protruding part of the side wall of the mold and be held in this position during casting of concrete poured from a casting machine movable along the mold.
