    Abstract: An elongated mold box encloses a removable rectangular pallet and has a center portion pivotally supported by a carriage which is supported for vertical movement by a pair of vertical guide posts mounted on a frame. Hydraulic cylinders are connected to move the carriage vertically relative to the frame and pivot the mold box relative to the carriage for tilting the mold box between a vertical concrete filling position and a horizontal position for stripping a molded concrete article from the mold box. The pallet is supported within the mold box by a generally flat tray member which is guided by parallel rails within the mold box and aligned horizontal guide rails on a run-out platform. The mold box also carries a hydraulic cylinder for moving the tray member between a retracted position within the mold box and an extended position on the run-out platform.
