Abstract
(DE)
Eine Spritzgiessmaschine dient zum Herstellen von Spritzlingen, insbesondere von Zahnbürstenkörpern oder Zahnbürsten, wobei die Spritzgiessmaschine ein Spritzgiesswerkzeug (1) und eine Spritzeinheit (2), insbesondere mit einem Schneckenkolbenextruder oder dergleichen Fördereinrichtung aufweist. Von der Spritzeinheit (2) führen Verteiler- oder Zuführkanäle einer Verteilerkanal-Anordnung (4) zu den einzelnen Formhöhlungen (5). An die Verteilerkanäle und/oder die Formhöhlungen (5) sind eine oder mehrere Zuführungen (10) für wenigstens einen Zuschlagstoff, zum Beispiel flüssige Farbe (8) angeschlossen.
(EN)
The invention relates to an injection molding machine for producing injection-molded articles, especially toothbrush bodies or toothbrushes. The inventive injection molding machine comprises an injection molding tool (1) and an injection molding component (2), especially a screw-piston type extruder or a similar delivery means. Distributor or feeder channels of a distributor channel system (4) extend from the injection molding component (2) to the individual mold cavities (5). One or more feeder ducts (10) for at least one aggregate, for example liquid paint (8), are connected to said distributor channels and/or mold cavities.
(FR)
L'invention concerne une machine de moulage par injection servant à produire des objets moulés par injection, notamment des corps de brosses à dents ou des brosses à dents. Cette machine de moulage par injection comporte un outil de moulage par injection (1) et une unité d'injection (2), notamment avec une extrudeuse à vis sans fin ou un système d'alimentation de ce type. Des canaux de répartition ou d'alimentation d'un système de canaux de répartition (4) partent de l'unité d'injection (2) jusqu'aux empreintes (5) individuelles des moules. Il est prévu une ou plusieurs conduites d'amenée (10) pour au moins un agrégat, par exemple un colorant liquide (8), raccordée(s) aux canaux de répartition et/ou aux empreintes (5) des moules.
