Claims19
A rotary device for a horizontal injection molding machine, comprising a base plate constructed in the absence of a passageway for a tie bar between fixed and moving mold mounting plates of the injection molding machine;
- a rotary table supported on the base plate for rotation about a vertical rotation axis;
- drive means for rotating the rotary table, wherein the drive means includes a pivot pin extending downwards from the rotary table and projecting through the base plate;
- and a shifting mechanism comprised of two racks with interposed gear for moving the base plate in longitudinal direction.
A horizontal injection molding machine, comprising:
- a machine bed defining a longitudinal axis;
- a first mold mounting plate fixedly secured onto the machine bed;
- a second mold mounting plate supported on the machine bed and movable relative to the first mold mounting plate;
- a rotary device arranged between the first and second mold mounting plates and including a base plate, a rotary table supported on the base plate for rotation about a vertical axis, and drive means for rotating the rotary table;
- and
- shifting means for displacing the rotary device in a direction parallel to the longitudinal axis
- wherein the base plate and the second mold mounting plate are guided on different guides.
