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).
Claims20
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.
A transfer unit for an injection molding device, the transfer unit comprising:
- a column having a first media interface in an area of said column's lower end when said column is in an operational orientation;
- and
- a sleeve having a second media interface in an area of said sleeve's upper end when said sleeve is in an operational orientation, said second media interface suitable to exchange liquid and/or gaseous media with a center part of the injection molding device, wherein the transfer unit is configured for assembly and disassembly independent of the center part.
A method to disassemble an injection molding device, comprising:
- providing an injection molding device having a center part and a rotating device arranged to hold and rotate the center part in the injection molding device, wherein the rotating device includes a base supported with respect to an injection molding machine, a column attached to the base and extending in an axial direction above the base, and a sleeve coaxially surrounding the column and at least partially arranged in the center part, the sleeve configured to rotate with the center part around the column;
- and
- separating the column from the center part while the column or the center part remains in the injection molding device.
