Abstract
An injection molding device (1) includes a center part (3) and a rotating device (2) for rotating the center part (3) in the injection molding device (1). The rotating device (2) includes a base (4) supported with respect to an injection molding machine. A thereto attached column (5) extends to an axial direction (z) above the base (4). A sleeve (6) coaxially surrounds the column (5) and is at least partially arranged in the center part (3). The sleeve (6) rotates with the center part (3) around the column (5). The column (5) is arranged removable with respect to the center part (3).
Claims17
A rotating device arranged to hold and rotate a center part in an injection molding device of an injection molding machine, the rotating device comprising:
- a base supportable with respect to the injection molding machine;
- a column attached to the base and extending in an axial direction above the base, the column being removable with respect to the center part;
- a sleeve coaxially surrounding the column and at least partially arranged in the center part, wherein the sleeve is arranged to rotate with the center part around the column;
- one or more grooves arranged between the column and the sleeve to exchange liquid and/or gaseous media between the column and the sleeve;
- and
- a support arranged to fix the center part with respect to the base when the column is removed from the center part.
