Abstract
An injection molding machine of the present invention includes a first mold half having one of at least one mold cavity and at least one mold core and a rotatable turret block rotatable on an axis for rotating a plurality of movable mold halves thereof into alignment with the first mold half. Each of the movable mold halves include one of at least one mold cavity and at least one mold core matable with the first mold half for forming a mold for molding a molded article. The rotatable turret block is further for clamping the movable mold halves and the first mold half together. The machine further includes a mechanism for moving the rotatable turret block relative the first mold half a first injector for injecting melt into the at least one mold cavity.
Claims47
An injection molding machine, comprising:
- an injection molding machine having only two platens and including a first platen carrying a first mold half having a central axis and one of at least one mold cavity and at least one mold core;
- a second platen in association with said first platen, said second platen comprising a rotatable turret means rotatable on a central axis of rotation for rotating a plurality of movable mold halves thereof into alignment with said first mold half, each of said movable mold halves including one of at least one mold cavity and at least one mold core matable with said first mold half for forming a mold for molding a molded article, said rotatable turret means operative for clamping said movable mold halves and said first mold half together;
- means for moving said rotatable turret means relative said first mold half;
- and
- a first injection means for injecting melt into said at least one mold cavity,
- wherein the central axis of rotation of the turret is perpendicular to the central axis of the first mold half.
