Two pairs of lever arms, fulcrumed on one of two relatively movable mold portions, form part of an articulated linkage anchored to the other mold portion and connected with either a stripper plate between the two mold portions or an ejector plate behind the second mold portion. Upon the opening of the mold, the stripper or ejector plate moves relatively to the adjacent mold portion, in a direction discharging the molded articles from the mold cavities, at a rate substantially conforming to a Gaussian curve. The linkage may include a lost-motion coupling to hold the plate in an inoperative position during a terminal phase of a closure stroke.
