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 in 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).
Claims21
An injection molding device (1) comprising a center part (3) and a rotating device (2) for holding and rotating the center part (3) in the injection molding device (1), the rotating device (2) comprising:
- a. a base (4) supported with respect to an injection molding machine,
- b. a column (5) attached to the base (4) extending in an axial direction (z) above the base (4) and
- c. a sleeve (6) coaxially surrounding the column (5) and at least partially arranged in the center part (3), wherein the sleeve (6) rotates with the center part (3) around the column (5), wherein
- d. grooves (7), used to exchange liquid and/or gaseous media between the column (5) and the sleeve (6), are arranged between the column (5) and the sleeve (6) and wherein
- e. the column (5) is arranged removable with respect to the center part (3);
- f. a support, wherein the center part (3) is fixed with respect to the base (4) by the support when the column (5) is removed from the center part (3).
A transfer unit (43) for an injection molding device (1), the transfer unit (43) comprising:
- a. a column (5) comprising in an area of its lower end in an operational orientation a first media interface (39);
- and
- b. a sleeve (6) comprising in an area of its upper end in an operational orientation a second media interface (40) suitable to exchange liquid and/or gaseous media with a center part (3) of the injection molding device (1), wherein the sleeve and the column form the transfer unit which is configured for assembly and disassembly independent of the center part.
A method for the disassembly of an injection molding device (1) comprising the following method steps:
- a. providing an injection molding device (1) comprising a center part (3) and a rotating device (2) for holding and rotating the center part (3) in the injection molding device (1), the rotating device (2) comprising a base (4) supported with respect to an injection molding machine, a column (5) attached to the base (4) extending in an axial direction (z) above the base (4) and a sleeve (6) coaxially surrounding the column (5) and being at least partially arranged in the center part (3), wherein the sleeve (6) rotates with the center part (3) around the column (5);
- b. separating the column (5) from the center part (3) while the column (5) or the center part (3) remain in the injection molding device (1).
