Description

Die Erfindung betrifft Spritzmaschinen zur Herstellung von schlauchartigen Körpern aus spritzbaren Stoffen jeder Art, insbesondere von Mänteln bzw. Hüllen für elektrische Leitungen und Kabel. The invention relates to injection molding machines for the production of hose-like Bodies made of injectable materials of all kinds, in particular coats or shells for electrical lines and cables.

Die Erfindung bezweckt, die Einstellung der Spritzwerkzeuge zu erleichtern und gewisse hierbei bisher auftretende Störungen zu vermeiden.The aim of the invention is to facilitate the adjustment of the injection molding tools and to avoid certain disturbances that have occurred so far.

Die Spritzwerkzeuge selbst bestehen in der Regel aus einem feststehenden hohlen Dorn und einer hierzu konzentrischen Düse, wobei der Außendurchmesser des Dornes den Innendurchmesser und der Innendurchmesser der Düse den Außendurchmesser des zu spritzenden Schlauches festlegen. Um eine gleichmäßige Wandstärke des Schlauches bzw. der Leitungshülle zu erreichen, müssen Düse und Dorn in bezug aufeinander einstellbar sein. Zu diesem Zweck ist üblicherweise die Düse an einem Ring befestigt, der im Mundstück der Spritzmaschine mit Hilfe von vier Stellschrauben allseitig verschoben werden kann. Hierfür muß zwischen dem Außendurchmesser des Ringes und dem Innendurchmesser des den Ring aufnehmenden Teiles des Mundstückes ein entsprechender Zwischenraum verbleiben. Dieser Zwischenraum läßt sich, wie die Erfahrung zeigt, nicht völlig gegenüber dem Spritz -kopf abdichten. Dies hat den Nachteil, daß er allmählich von dem Spritzwerkstoff ausgefüllt wird. The injection molds themselves usually consist of a stationary one hollow mandrel and a nozzle concentric thereto, the outer diameter of the The mandrel is the inside diameter and the inside diameter of the nozzle is the outside diameter of the hose to be sprayed. To ensure a uniform wall thickness of the hose or the cable sheath, the nozzle and mandrel must be adjustable with respect to one another be. For this purpose, the nozzle is usually attached to a ring that is in the The mouthpiece of the injection molding machine moved on all sides with the help of four adjusting screws can be. For this there must be between the outer diameter of the ring and the inner diameter of the part of the mouthpiece receiving the ring a corresponding space remain. As experience shows, this gap cannot be completely eliminated seal against the spray head. This has the disadvantage that it gradually decreases the spray material is filled.

Der Ring setzt dann einer Verschiebung einen so großen Widerstand entgegen, daß die Stellsehrauben abbrechen, wodurch häufig auch die Spritzköpfe unbrauchbar werden.The ring then puts so great resistance to displacement counter to the fact that the adjusting screws break off, which often also causes the spray heads become unusable.

Die Mängel der bekannten Einstelivorrichtung der Spritzdüse sind erfindungsgemäß dadurch behoben, daß die Spritzdüse exzentrisch in einer runden Scheibe befestigt ist, die ihrerseits drehbar exzentrisch in einer zweiten runden Scheibe gelagert ist, welche wiederum drehbar in einer run,den Ausnehmung des Spritzkopfes angeordnet ist. The shortcomings of the known adjusting device for the spray nozzle are solved according to the invention in that the spray nozzle eccentrically in a round Disc is attached, which in turn can be rotated eccentrically in a second round Disc is mounted, which in turn can be rotated in a run, the recess of the spray head is arranged.

Durch Verdrehung der beiden exzentrischen Scheiben gegeneinander kann jede Lage der Spritzdüse in bezug auf den Spritzdurn eingestellt werden, ohne daß für die Verstellung der Spritzdüse ein Zwischenraum zwischen Spritzkopf un;d Düsenträger erforderlich ist.By turning the two eccentric disks against each other, you can each position of the spray nozzle with respect to the spray diameter can be adjusted without To adjust the spray nozzle, there is a space between the spray head and the nozzle holder is required.

Ein Ausführungsbeispiel der Erfindung ist im folgenden an Hand der Zeichnung beschrieben. In dieser zeigt Fig. I einen Schnitt durch den Spritzkopf einer Spritzmaschine gemäß der Erfindung, Fig. 2 eine Ansicht von yorn und Fig. 3 einen Schnitt nach Linie III-III der Fig. I. An embodiment of the invention is shown below with reference to the Drawing described. In this Fig. I shows a section through the spray head an injection molding machine according to the invention, FIG. 2 is a view of yorn and FIG. 3 shows a section along line III-III of Fig. I.

In der Zeichnung ist das vordere Ende des Spritzkopfes mit I bezeichnet. In diesem ist ein Spritzdorn 2 eingesetzt. Der Spritzdorn ist über Rippen 3 an einem Ring 4 befestigt. Dieser Ring sitzt in einer Ausnehmung 5 des Spritzkopfes I. The front end of the spray head is denoted by I in the drawing. In this a spray mandrel 2 is used. The spray mandrel is on ribs 3 on one Ring 4 attached. This ring sits in a recess 5 of the spray head I.

Die Spritzmaschine dient zum Umspritzen voll elektrischen Leitungen, wobei diese durch die Bohrung 6 des Spritzdornes 2 hindurchgezolgen werden. Das Spritzgut selbst wird von der nicht dargestellten Schnecke durch die Öffnungen 7 zwischen den Rippen 3 der Spritzdüse 8 zugeführt. The injection molding machine is used to encapsulate fully electric cables, these being pulled through the bore 6 of the spray mandrel 2. That The material to be sprayed is fed through the openings 7 by the screw (not shown) fed between the ribs 3 of the spray nozzle 8.

Diese Spritzdüse sitzt fest in einem Düsenhalter 9, der aus einem zylindrischen Teil IO, einem Teil 11 mit Außengewinde 12 und einem als Schlüssel ausgebildeten Teil 13 besteht. Der Düsenhalter ist exzfentrisch in eine Bohrung 14 eines zylindrischen Körpers 15 eingeschraubt. Dieser ist drehbar, aber axial verschiebbar in einem zweiten zylindrischen Körper I6 gelagert, welcher wiederum in der gleichen Weise, d. ,. exzentrisch und axial unverschiebbar, in einer Überwurfmutter I7 sitzt, die auf das Außengewinde I8 des vorderen Endes des Spritzkopfes I aufgeschraubt ist.This spray nozzle is firmly seated in a nozzle holder 9, which consists of a cylindrical part IO, a part 11 with external thread 12 and one as a key trained part 13 consists. The nozzle holder is eccentric in a bore 14 of a cylindrical body 15 is screwed. This is rotatable, but axial slidably mounted in a second cylindrical body I6, which in turn in the same way, d. ,. eccentrically and axially immovable, in a union nut I7 sits, which is screwed onto the external thread I8 of the front end of the spray head I. is.

Der Umfang 19 der Mutter 17 ist, wie üblich, als Sechskant aungebildet. Der Umfang 20 des Körpers I6 ist in der unteren Hälfte halbkreis förmig, während er in der oberen Hälfte zwei ebene Flächen für den Ansatz eines Stellschlüssels aufweist. In der gleichen Weise ist der Umfang 21 des Körpers I5 ausgebildet, nur daß hier die ebenen Flächen unten und der halbkreisförmige Teil oben liegen. The scope 19 of the nut 17 is, as usual, aunebilden as a hexagon. The circumference 20 of the body I6 is semicircular in the lower half, while he has two flat surfaces in the upper half for the approach of a key having. The circumference 21 of the body 15 is formed in the same way, only that here the flat surfaces are below and the semicircular part is above.

Der schlüsselartige Teil I3 des Düsenhalters 9 dient zur Längsverstellung der Düse S. The key-like part I3 of the nozzle holder 9 is used for longitudinal adjustment the nozzle S.

Wie die Fig. 3 erkennen läßt, kann durch Drehen der Teile 15 und I6 die Lage des Mittelpunktes der Spritzdüse in bezug auf den Mittelpunkt des Spritzdornes innerhalb der gegebenen,Exzentrizitäten verschoben werden und hierbei innerhalb dieser Grenzen jede Lage zur Achse der Spritzmaschine und damit des Spritzdornes einnehmen. Die Verdrehung erfolgt durch Schlüssel, die auf die Flächen 20 und 21 aufgesetzt werden. As can be seen in FIG. 3, by rotating the parts 15 and I6 the position of the center of the spray nozzle in relation to the center of the spray mandrel within the given, eccentricities are shifted and thereby within these limits each position to the axis of the injection molding machine and thus the injection mandrel take in. The rotation is carried out by means of keys that are placed on surfaces 20 and 21 be put on.
