Description
"Vorrichtung zum Herstellen von Flaschen aus thermoplastischem Kunststoff
nach dem Blasverfahren."
Es ist ferner bekannt, bei einer Maschine zum Herstellen von Kunststofflaschen,
bei welcher von einer Spritzdüse zunächst eine Blase ausgepresst wird, konzentrisch-'innerhalb
des Kerns der ringförmigen Spritzdüse die Blasdüse anzuordnen. Praktisch
Die Erfindung bezieht sich auf eine weitere Ausgestaltung des erstgenannten
Verfahrens. Das Neue besteht dabei zunächst darin, dass die Blasdüse unter Belassung
eines etwa ringförmigen Spaltes aus dem Innenring der Spritzdüse hervortritt. Bei
dieser Ausbildung ergibt sich der Vorteil, dass sich die Blasdüse beim Schliessen
der Form nach Bedarf etwas zur Seite hin verschieben kann. Das ist wichtig, um z.
B. auch dann ein zwängungsfreies Schliessen der Form zu erreichen, wenn die Wandstärke
des Schlauches, z. Bo bedingt durch Temperaturunterschiede im Schlauch, nicht allseitig
genau gleich sein sollte. Die
Praktisch ist das aber ohne Bedeutung, zumal in der Regel die . Wandstärke am Flaschenhals ohnehin grösser ist als am Flaschenbauch.In practice, however, this is irrelevant, especially since usually the. Wall thickness is larger on the neck of the bottle than on the belly of the bottle.
In weiterer Ausbildung der Spritzdüse gemäss der Erfindung ist die Blasdüse heb-und senkbar gegenüber der ringförmigen Spritzdüse. Auf diese Weise besteht die Möglichkeit, nach der Fertigstellung der Flasche während des Öffnens der zweiteiligen Form die Blasdüse ruckartig zurückzuziehen. Das ist insbesondere dann von Wichtigkeit, wenn der Flaschenhals mit Innengewinde oder sonstigen vorspringenden Teilen versehen ist. Die Praxis hat gezeigt, dass unmittelbar nach der Formgebung der Flasche auch in einem solchen Fall ! der Dorn ohne Gefährdung der aufspringenden Teile im Hals der Flasche zurückgezogen werden kann, da der thermoplastische Kunststoff zunächst noch hinreichend warm ist und daher noch eine ausreichende elastische Nachgiebigkeit aufweist.In a further embodiment of the spray nozzle according to the invention is the Blowing nozzle can be raised and lowered in relation to the annular spray nozzle. In this way there is a possibility after the completion of the bottle during opening pull back the nozzle with a jerk of the two-part mold. That is particular then of importance if the bottle neck has an internal thread or other protruding Share is provided. Practice has shown that immediately after shaping the bottle even in such a case! the thorn without endangering the springing one Parts in the neck of the bottle can be withdrawn as the thermoplastic material initially still sufficient is warm and therefore still sufficient has elastic compliance.
Durch den Spalt zwischen dem Innenring der Spritzdüse und. der Blasdüse kann Luft hindurch geblasen werden. Diese Blasluft streicht somit an der Aussenwand der Blasdüse entlang. Dadurch wird die Blasdüse gekühlt und ein Kleben des thermoplastischen Kunststoffes an ihrer Aussenwand mit Sicherheit verhindert. Through the gap between the inner ring of the spray nozzle and. the nozzle air can be blown through. This blown air thus brushes against the outer wall along the air nozzle. This cools the nozzle and causes the thermoplastic to stick Prevents plastic on their outer wall with security.
Da die Blasdüse nicht in unmittelbarer Berührung mit dem Innenring der Spritzdüse steht, ist sie ohnehin schon weitgehend gegen einen Wärmeübergang isoliert. Because the air nozzle is not in direct contact with the inner ring the spray nozzle, it is already largely against a heat transfer isolated.
Die Hohlform kann als Doppelform mit zwei übereinander liegenden Formnestern ausgeßtiMet sein, die durch eine Trennwand voneinander geschieden sind. In einem sochen Falle ragt ausser der aus der Mitte der Spritzdüse hervortretenen Blasdüse von unten her eine zweite Blasdüse in das untere Formnest hinein. In diesem Falle werden aus dem einen eingeklemmten Schlauchabschnitt gleichzeitig zwei Flaschen gewonnen. Der aus der Spritzdüse austretende Schlauch wird dabei mit seinem offenen Ende über die untere Blasdüse geschoben. The hollow shape can be a double shape with two superimposed Mold cavities which are separated from one another by a partition. In one such case, the one protruding from the center of the spray nozzle protrudes Blowing nozzle from below a second blowing nozzle into the lower mold cavity. In this The trap becomes two bottles at the same time from a clamped tube section won. The hose emerging from the spray nozzle is open with its End pushed over the lower air nozzle.

Bei dem Ausführungsbeispiel entsprechend Fig. 2 der Zeichnung ist
im Gegensatz zu der beschriebenen Einrichtung eine Form 20 mit zwei übereinander
liegenden Formnestern 21 und 22 vorgesehen, die durch die Trennwand 23 voneinander
geschieden sind. In diesem Falle erstrecken sich die Schneidkanten 18 auch über
die Stoßeskanten der Trennwand 23. Ferner ragt bei dieser Ausbildung eine zweite
Blasdüse 24, die der ersten Blasdüse 14 genau gegenüberliegt, von unten her in das
untere Formnest 22 hinein. In diesem Falle wird der Schlauch 16, der ohnehin die
Blasdüse 14 umgibt,
von oben her über die zweite Blasdüse 24 geschoben,
