Description

Die Erfindung bezieht sich auf eine weitere Ausbildung der im Patent 1435780 geschützten Spritzgußvorrichtung zur Herstellung von an Tragbändern befestigten Reißverschlußgliedern aus Kunststoff, bestehend aus zwei endlosen umlaufenden Bändern, die mit einander ergänzenden Formteilen versehen sind, und einer die Bänder zusammendrückenden Einspritzvorrichtung. The invention relates to a further embodiment of the patent 1435780 protected injection molding device for the production of fastened to lanyards Zipper links made of plastic, consisting of two endless circumferential bands, which are provided with complementary molded parts, and one that compresses the bands Injector.

Nach dem Hauptpatent ist eine solche Spritzgußvorrichtung dadurch gekennzeichnet, daß zur kontinuierlichen Herstellung der Reißverschlußglieder die auf den stetig umlaufenden Bändern oder Ketten angeordneten oder in sie eingesenkten Formteile sich zu am Bänderrand offenen Formen ergänzen und die Einspritzvorrichtung an der Einspritzseite aus einem über den Formöffnungen in Bewegungsrichtung der Bänder sich entlang einer Wand bis nahezu zum Verschluß der Formen verengenden Kanal besteht. According to the main patent, such an injection molding device is characterized characterized in that for the continuous production of the zipper members arranged on or sunk into the continuously rotating belts or chains Molded parts complement each other to forms open at the edge of the band and the injection device on the injection side from one above the mold openings in the direction of movement of the Ribbons along one wall up to the channel narrowing almost to the closure of the molds consists.

Der vorliegenden Erfindung liegt Aufgabe zugrunde, die genannte Spritzgußvorrichtung mit austauschbaren Formen zu versehen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Formteile als besonders hergestellte Körper auf die Bänder aufgesteckt sind. Das Abfallen der Formteilkörper auf denjenigen Teilen der Bandwege, auf denen die Formteile der beiden Bänder nicht zusammengepreßt werden und sich somit gegenseitig an den Bändern festhalten, wird durch am Bandweg angeordnete Blechbahnen verhindert. The present invention is based on the aforementioned injection molding device to be provided with interchangeable shapes. This object is achieved according to the invention solved that the molded parts are attached to the belts as specially manufactured bodies are. The fall of the molded body on those parts of the tape paths on which the molded parts of the two bands are not pressed together and thus against each other Holding on to the belts is prevented by sheet metal strips arranged on the belt path.

Damit die mit Zapfen in Ausnehmungen der Bänder eingesetzten Formteilkörper am Band einen möglichst guten Halt finden, müssen die Bänder möglichst dick sein. Damit sie trotzdem über Transportwalzen mit geringem Durchmesser laufen können, sind sie zweckmäßig mit Quernuten versehen. So that the molded body inserted with pegs in recesses of the belts find the best possible hold on the tape, the tapes must be as thick as possible. So that they can still run over transport rollers with a small diameter, they are appropriately provided with transverse grooves.

Die Zeichnung zeigt beispielsweise schematisch und teilweise im Schnitt eine bevorzugte Ausführungsform einer Spritzgußvorrtchtung der Erfindung. The drawing shows, for example, schematically and partially in section a preferred embodiment of an injection molding apparatus of the invention.

Es zeigt Fig. 1 eine Draufsicht auf die Vorrichtung, Fig. 2 eine Ansicht eines Bandstückes von einer Seite, Fig. 3 eine Ansicht des Bandstückes nach Fig. 2 von der anderen Seite, Fig. 4 -eine - Draufsicht auf ein Bandstück nach Fig. 2, Fig. 5 eine Draufsicht auf die Bandränder und die Öffnungen der Formteile, die sich zu vollständigen Formen ergänzt haben, und Fig. 6 einen Schnitt nach Linie V-V der Fig. 5.1 shows a plan view of the device, and FIG. 2 shows a view of a piece of tape from one side, FIG. 3 is a view of the piece of tape according to FIG. 2 from the other side, Fig. 4 - a - plan view of a piece of tape according to Fig. 2, Fig. 5 is a plan view of the tape edges and the openings of the mold parts, which to have completed forms, and Fig. 6 is a section along line V-V of Fig. 5.

Die beiden Bänder 1, 1' laufen über je zwei Transportwalzen 5, 5'. Sie durchlaufen gemeinsam die Einspritzvorrichtung 3, in der die von ihnen getragenen Formteile 2, 2' sich zu vollständigen Formen ergänzen, die über den Kanal 4 von einem Extruder mit plastifiziertem Kunststoff gefüllt werden, und anschließend die Kühlkammer 9. An den Transportwalzen 5,5' und den Rücklaufwegen sind die Bänderl, 1' von Blechbahnenl3, 13'umhüllt, die ein Abfallen der aufgesteckten Formteilkörper 17, 17' verhindern. The two belts 1, 1 'each run over two transport rollers 5, 5'. Together they pass through the injection device 3, in which the ones carried by them Molded parts 2, 2 'complement each other to form complete shapes, which via the channel 4 of an extruder filled with plasticized plastic, and then the Cooling chamber 9. On the transport rollers 5.5 'and the return paths are the belts, 1 'encased by sheet metal websl3, 13' which prevent the attached molded body from falling off 17, 17 'prevent.

Zum Aufstecken der Formteilkörper 17, 17' weisen die Bänder l, 1' Ausnehmungen 14 auf, in die Zapfen 16, 16' an der Rückseite der Formteilkörper 17, 17' passen. Damit die Bänder 1, 1' schmiegsam bleiben, sind sie mit Quernuten 15 versehen. 7 ist das Textilband, auf das die Glieder gespritzt werden. To attach the molded body 17, 17 ', the bands 1, 1' Recesses 14, in the pin 16, 16 'on the back of the molded body 17, 17 'fit. So that the strips 1, 1 'remain pliable, they are provided with transverse grooves 15 Mistake. 7 is the textile tape on which the links are injected.
