Molding machine with vibration isolation

Abstract

A concrete block molding machine has the pallet support table mounted on the main frame of the machine through pneumatic tires which provide vibration isolation between the pallet support table and the main machine frame. A mold, having vibrating mechanism mounted on it is lowered into position on pallets supported by the pallet support table, and the mold and pallet support table are clamped together on opposite sides of a pallet during the molding operation. A plunger head is carried on the main machine frame through additional air bag vibration isolators to engage materials in the mold to compact them during the molding operation while the vibrators are operating. Upon completion of the molding operation, the table and mold are unclamped to permit a stripping plate to move the mold upwardly off of the pallet; so that the pallet and the green concrete blocks may be moved out of the machine and a new pallet may be positioned for the next cycle of operation.
