Method and apparatus for control of an ejector mechanism of a molding machine. A procedure is executed without operator intervention for setting limits for controlling motion of movable members of mold assemblies, the movable members linked to ejector pins communicating with the mold cavity and used

Method and apparatus for control of an ejector mechanism of a molding machine. A procedure is executed without operator intervention for setting limits for controlling motion of movable members of mold assemblies, the movable members linked to ejector pins communicating with the mold cavity and used to assure molded articles are dislodged from a mold element. The procedure, typically associated with a "set-up" mode of control, operates an ejector mechanism with reduced force to drive the movable members to the extremes of travel thereof, senses a "stalled" condition at each extreme, and causes measured position of each extreme to be recorded. Position values intended for use in normal (program controlled) operation of the molding machine are derived from the recorded position values.
