ABSTRACT:
Machinery and methods for making concrete blocks includes an open top and open bottom mold supported on a machine's frame when the mold is at rest. A pallet support beneath the mold is movable upwardly by means of a pallet lifter frame to clamp a pallet against the bottom of the mold. Upward movement of the pallet support is accompanied by upward movement of the mold off the frame to enable vibration of the mold without the generation of noise between the mold and the frame. A stripper head is supported above the mold for entry into the latter during vibration of the mold to assist in compacting moldable material within the mold. The stripper head is carried by a movable frame the movements of which are controlled by a cam and an interconnecting linkage, and the stripper head is vertically movable relative to the frame. Inflatable/deflatable cushions or absorbers are interposed between the stripper head and the stripper head frame to minimize noise. Additional inflatable/deflatable absorbers are interposed between the stripper head and the stripper head frame and which act in conjunction with the first mentioned absorbers to effect movement of the stripper head relative to the stripper frame and to the mold in advance of block stripping operations to avoid crushing the molded blocks as they are stripped from the mold.
