Abstract
An injection-molding assembly has a fixed mold plate carrying a centering ring, a fixed mold half carrying a centering ring snugly interfitted with the fixed-plate centering ring, a movable mold plate carrying a centering ring, and a movable mold half carrying a centering ring snugly interfitted with the movable-plate centering ring. One of the rings is formed of an outer ring part having a substantially circular outer periphery and a substantially circular inner periphery and of an inner ring part having a substantially circular outer periphery and a Substantially circular inner periphery. The outer periphery of one of the ring parts has a center of curvature offset radially from a center of curvature of the respective inner periphery. The annular parts can be angularly displaced and can be clamped relative to each other.
