Injection molding machine has a section for plastics closure caps, with an inner threading, and an ejector unit working with the ejector plate, to give part of the ejection action before the mold is opened using a toothed rack

摘要

Injection machine has a section to produce plastics closure caps with an inner threading, and a rotating ejector unit for the finished caps. The ejector is rotated, with its toothed path against the round toothed path on a rotating return cylinder. The cylinder has a drive take-off toothed path so that there is a reduction ratio between them through different diameters and/or tooth counts. The injection machine (2) has a section (1) to produce plastics closure caps with an inner threading, and a rotating ejector unit (3) for the finished caps working with the sliding ejector plate (4). The ejector is rotated by a rack (5), with its toothed path (12) against the round toothed path (13) on a rotating return cylinder (14). The cylinder has a drive take-off toothed path (15), at a gap from the first toothed path, so that there is a reduction ratio between them through different diameters and/or tooth counts.
