An injection-molding apparatus has a housing, a plate fixed on the housing, a plurality of fixed mold halves on the fixed plate, a plate movable along an axis toward and away from the fixed plate and supported on the housing without tie rods, respective movable mold halves on the movable plate engageable with the fixed mold halves, and an actuator rod passing axially through the fixed plate between the fixed mold halves and having an outer end fixed to the movable plate and an opposite inner end. An actuator fixed to the housing and to the inner rod end displaces the movable mold plate and the movable mold halves axially toward and away from the fixed mold plate and fixed mold halves.
