Abstract: An apparatus for molding shaped bodies from foamable plastics such as foamable polyurethane resin material comprises a two-piece mold 20, 21 fastened to two clamping plates 17, 18 of a mold holder 11, all of which can revolve around parallel axes 34, 35, 36. The upper plate 18 can move toward the fixed lower plate 17 and back again. The plates are locked and urged together during the molding process by pairs of hydraulic cylinders 28, 29 and 30, 31 mounted on opposite sides of the mold halves 20, 21.

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.

Abstract: Apparatus for producing molded objects from foamable plastics in which a bipartite mold is secured to two movable clamping plates. One of the clamping plates is movable through at least an angle of 180.degree. from a parallel position with respect to the other clamping plate.
