Apparatus for injection-molding threaded plastic caps and stoppers |
摘要 |
In injection-molding threaded molded articles in the form of plastic caps and stoppers with or without imbedded reinforcing cages, an injection unit, a closing unit and an injection mold are provided, where the movable mold half is equipped with a threading part. The threading part is irrotational and integral. A rotating tool is provided, which for the condition of open injection mold can be moved between the mold halves and is operationally linked to the molded article so it can be jointly moved with it to unscrew the molded article from the threading part. Radial and axial centering pins are provided in the injection mold to center the cage.
