Abstract
The invention relates to a retaining device (1) for a rotatable mold center part (2) in an injection molding machine, the retaining device comprising a plate (17) used for retaining the rotatable mold center part (2), the plate being rotatable about an axis of rotation (16) and driven by means of a motor (20). The retaining device (1) comprises a lower cross member (10), which is mounted movably in the longitudinal direction (x) on guide rails (7) while supported on a machine bed (6) of the injection molding machine by means of first bearing blocks (8). The retaining device (1) comprises second bearing blocks (23), by means of which the lower cross member (10) is supported in the circumferential direction relative to lower beams (5) of the injection molding machine.

A holding device (1) for a mold comprising a rotatable mold center part (2) in an injection molding machine comprising:
- a lower cross member (10) which is mounted movably in a longitudinal direction (x) of tie bars (5) and guide rails (7) while first bearing blocks (8) are attached to the lower cross member (10) which support the lower cross member (10) via the guide rails (7) on a machine bed (6) of the injection molding machine in a vertical direction (z), and
- a plate (17) which is rotatable with respect to the lower cross member about an axis of rotation (16) extending in the vertical direction and driven by a drive torque of a motor (20), the plate (17) serving to hold the rotatable mold center part (2), wherein
- second bearing blocks (23) attached on opposite sides of the lower cross member (10) support the lower cross member (10) in a circumferential direction relative to a pair of lower tie bars (5) of the injection molding machine, and wherein
- weight forces acting in the vertical direction are transmitted to the machine bed (6) via the first bearing blocks (8) and the guide rails (7) and reaction forces of the drive torque are transmitted to the lower tie bars (5) via the second bearing blocks 23 and wherein
- the second bearing blocks (23) arranged on opposite sides of the lower cross member (10) are arranged in pairs on the tie bars (5) at a distance (a) from one another.
A holding device (1) for a mold comprising a rotatable mold center part (2) in an injection molding machine comprising:
- a lower cross member (10) which is mounted movably in a longitudinal direction (x) of tie bars (5) and guide rails (7) while supported via first bearing blocks (8) via the guide rails (7) on a machine bed (6) of the injection molding machine in a vertical direction (z), and
- a plate (17) which is rotatable with respect to the lower cross member about an axis of rotation (16) extending in the vertical direction and driven by a drive torque of a motor (20), the plate (17) serving to hold the rotatable mold center part (2),
- wherein second bearing blocks (23) support the lower cross member (10) in a circumferential direction relative to a pair of lower tie bars (5) of the injection molding machine, and
- wherein weight forces acting in the vertical direction are transmitted to the machine bed (6) via the first bearing blocks (8) and the guide rails (7) and the drive torque is transmitted to the lower tie bars (5) via the second bearing blocks 23 acting primarily in the circumferential direction, and
- wherein the second bearing blocks (23) arranged on opposite sides of the lower cross member (10) are arranged in pairs on the tie bars (5) at a distance (a) from one another.
A holding device (1) for a mold comprising a rotatable mold center part (2) in an injection molding machine comprising:
- a lower cross member (10) which is mounted movably in a longitudinal direction (x) of tie bars (5) and guide rails (7) while supported via first bearing blocks (8) via the guide rails (7) on a machine bed (6) of the injection molding machine in a vertical direction (z), and
- a plate (17) which is rotatable with respect to the lower cross member about an axis of rotation (16) extending in the vertical direction and driven by a motor (20), the plate (17) serving to hold the rotatable mold center part (2),
- wherein second bearing blocks (23) support the lower cross member (10) in a circumferential direction relative to a pair of lower tie bars (5) of the injection molding machine, and
- wherein the second bearing blocks (23) are arranged perpendicular with respect to the first bearing blocks (8) to support the lower cross member (10) in the circumferential direction, and
- wherein the second bearing blocks (23) arranged on opposite sides of the lower cross member (10) are arranged in pairs on the tie bars (5) at a distance (a) from one another.
