ABSTRACT:
A vertical frame supports a rotary indexing table which carries a pair of vertical shot sleeves each having a shot piston with a depending shot piston rod. The shot sleeves are alternately indexed between a metal receiving station and a metal transfer station where a mold is supported above the table by a gate plate mounted on the frame. A hydraulic ejection cylinder and a substantially larger hydraulic shot cylinder are supported by the frame under the metal receiving and transfer stations, respectively, and laterally sliding couplings alternately connect the shot piston rods to the hydraulic cylinders when the table is indexed 180.degree.. Each shot piston and the gate plate form a biscuit which is retracted into the shot sleeve at the transfer station by the shot cylinder and is ejected at the receiving station by the ejection cylinder after the table and shot sleeves are indexed.
