An actuator carriage for a multi-level injection molding apparatus having mold core and mold cavity support plates, tie bars supporting a moveable platen and having stripper mechanisms associated with mold cores mounted to the mold core support plates. The stripper mechanisms are displaced relative to the mold cores by lever arms having cam surfaces engaging actuators carried by the actuator carriage. Each actuator carriage includes a support bar extending generally transversely relative to the tie bars with at least one of the actuators being mounted on the support bar. At least one connector bar is rigidly secured to the support bar and a respective of the mold cavity support plates. The connector bar maintains the support bar at a fixed distance from the mold cavity support plate. The support bar is moveable along at least one of the tie bars and has a lateral restraining device limiting lateral movement of the support bar toward respective of the tie bars.
