Device for the manufacture of container closures by two-component injection moulding

摘要

The slide (9), or an additional slide, includes at least one projection (11). In the second position of the slide (9), this separates the region of the support section (6) onto which the hinge strip (4) is molded, from the region (8) of the support section onto which the tension strip (7) is molded. The slide (9) has two projections (11) to separate the regions of the bearing section from each other, in the second position. The projections are rod-like. They project parallel to the direction of motion of the slide and are also mutually-parallel. The projections are elongated rectangular sections. The slide is made of two or more components moving in the same direction. Each projection is formed from a slide component. A separate slide component exists for each clamping strip and support section. A horizontal slide with projections, travels between the region of the bearing section (6) onto which the hinge strip (4) is molded, and the region of the bearing section (8) where the tension strip is molded-on, to separate them from each other.
