Abstract (en)
[origin: US6402499B1] A vibration drive particularly suited for a mold for producing concrete molded bodies comprises of at least one piezoelectric vibration exciter which is fixedly attached onto the mold. The vibration exciter comprises a housing in which an unbalance mass is movably supported and is drivingly connected to a piezoelement which is also located in the housing to produce vibration. When an AC voltage is applied to the vibration exciter a deformation movement occurs which is converted into an oscillating motion of the unbalance mass and which thus produces vibrations of the mold.
