A vibration molding device comprising a pedestal, a mold configured to contain molding material, a vibration stand on which the mold is placed, a vibration means to provide vibration to the mold, an elastic body that is placed between the vibration stand and the pedestal to support the vibration stand, wherein the vibration molding device is characterized in that a through hole is formed in the vibration stand, a descent restriction member which regulates the descending position of the vibration stand is erected on the top surface of the pedestal, the descent restriction member is disposed so that the descent restriction member penetrates the through hole.

A hybrid vibration assembly for a concrete products machine. The assembly may include a vibration frame positioned to carry at least a portion of a mold, a stationary frame carrying the vibration frame, knocker bars supportable on the stationary frame for vertical adjustment relative to the stationary frame, and a motor connected to a vibrator mounted on the vibration frame. The assembly may also include a mechanical frame/mold clamp that alternately couples the vibration frame to the mold and decouples the vibration frame from the mold.

In a method and apparatus for vibrating a mold box of a type having a plurality of mold cavities sized and shaped to yield a predesignated molded product, the system comprises mounting the mold box to a frame within the expanse of a product forming machine and moving left and right sides of a yoke upward and downward independently through phases of a vibration sequence. The vibration sequence for each has a maximum and minimum lifting height such that the left and right sides of the yoke tilt with respect to one another dependent upon the vibration sequence. A central vibration rod couples between a central portion of the yoke and the frame so that the frame is vibrated at an approximate average between the upward and downward movement of the left and right sides of the yoke. Vibration frequency, amplitude, and phase difference can be adjusted to affect the vibration profile of the central vibration rod.

Disclosed is a vibration device with a vibrating table for a concrete block manufacturing machine for compression of a material to be compressed. The vibration device is at least partially resiliently mounted on a machine frame and driven by at least one electric motor. As a result the vibrating table can be set in a predominantly vertical vibrating movement, wherein the vibration device has a plurality of vibrating table bars arranged parallel to one another and fastened to the vibrating table and impact bars fastened statically to the machine frame. All the impact bars are displaceable relative to the vibrating table bars and along a displacement axis running parallel to the vertical vibrating movement by a plurality of positioning devices connected to one another and driven by at least one common drive unit in order to obtain a synchronous displacement of all the impact bars.
