ABSTRACT:
A pair of spaced, parallel guide posts 18, 19 are mounted on and perpendicular to a lower platen 12 which supports a first mold half 20. A traversing member 33 is slidably mounted on the guide posts, and an upper platen 13 supporting a second mold half 21 is hinged to the traversing member for pivotal movement about an axle 14 laterally offset from the lower platen. A double acting operating cylinder 15 is hingedly mounted to the lower platen near the guide posts and to the upper platen near the hinged axle 14, and controls both the movement of the upper platen toward and away from the lower platen in a parallel orientation, and the pivotal movement of the upper platen after the traversing member has reached its upper limit of travel.
