Abstract
An apparatus for making molded articles of plastic material, in particular molded films of thermoplastic flakes, by using a slush molding process, includes a mold container having at least one interior space for receiving plastic material and a mold wall which can be heated and cooled in alternating sequence. The mold container is located within a support frame which is rotatable about a rotation axis, whereby the suspension of the mold container is so configured as to allow a movement of the mold container in three degrees of freedom. The suspension includes a combined swivel and shift arrangement, which is disposed between the support frame and the mold container and supports the mold container in such a manner as to effect a rotation of the mold container about a pivot axis, which is perpendicular to the rotation axis, and a reciprocating motion in the direction of the pivot axis.
