Beschreibung
Zusammenfassung:	The vibrating drive is especially suited for a mold for producing concrete moldings and consists of at least one piezoelectric vibration exciter which is located stationary on the mold. The vibration exciter is formed by a housing in which an unbalance mass is movably supported and is drive-connected to a piezoelement which is likewise located with a vibration capacity in the housing. By applying an AC voltage to the vibration exciter, a deformation motion is formed which is converted into an oscillating motion of the unbalance mass and which thus produces vibrations of the mold. By using a different number of vibration exciters which can be made relative mall and compact in dimensions, and by their attachment to different points on the mold with a horizontal and/or vertical direction of vibration, the vibrating drive and thus the vibration behavior of the mold can be adapted to different operating conditions.
