ABSTRACT:
A concrete mold press for a concrete molding machine includes a reciprocating tamper operatively movable to an operative position in pressing contact with the concrete in a mold. The tamper includes a tamping plate mounted to vertically oscillate in response to the press head vibrations to repeatedly strike the press head to provide a tamping force which compacts the concrete in the mold.
