DEVICE FOR THE AUTOMATIC AND SIMULTANEOUS COMPENSATION OF AN ANGLE ERROR AND A AXIS OFFSET IN A CLOSING UNIT OF AN INJECTION MOLDING MACHINE

摘要

Apparatus for automatic and simultaneous compensation of angle error and axis offset in the closing unit of an injection molding machine includes moving and fixed mold mounting plates, a base plate on one mold mounting plate, and a mold carrier plate for receiving the half-mold of the one mold mounting plate, with the mold carrier plate tiltable relative to the base plate and the half-mold shiftable in parallel to the mold carrier plate. The base plate is connected to the mold carrier plate via a cup bearing at formation of a gap therebetween. The mold carrier plate is prestressed by a first prestressing assembly relative to the base plate, and the half-mold is prestressed by a second prestressing assembly against the mold carrier plate. A centering ring with a cone-like depression is provided on the one half-mold and another centering ring with a centering cone that matches the depression is provided on the other half-mold.
