Description
Die Erfindung betrifft eine Vorrichtung zum Verarbeiten von plastischen Massen, die mindestens zwei verschiebliche Formaufspannplatten umfaßt, an die je eine Plastifizier- und Einspritzeinheit angeordnet ist, wobei die mindestens zwei verschieblichen Formaufspannplatten aufeinander zu bewegbar sind, wobei zwischen den zwei verschieblichen Formaufspannplatten ein drehbares Mittelteil angeordnet ist, wobei das Mittelteil aus einem drehbaren und einem festen Teilelement besteht, wobei das drehbare Teilelement um seine vertikale Achse drehbar und das feste Teilelement ortsfest mit dem Maschinenbett verbunden ist und somit seine Position, bezogen auf das Maschinenbett, nicht veränderbar ist.The The invention relates to a device for processing plastic Compositions comprising at least two sliding mold platens, to which each a plasticizing and injection unit is arranged, wherein the at least two movable mold clamping plates on each other are movable, wherein between the two movable platens a rotatable central part is arranged, wherein the middle part of a rotatable and a fixed part element, wherein the rotatable part element rotatable about its vertical axis and the fixed Partial element is fixedly connected to the machine bed and thus its position, relative to the machine bed, not changeable is.
Gattungsgemäße Vorrichtungen
sind aus dem Stand der Technik bekannt. So beschreibt beispielsweise
die
Aufgabe der vorliegenden Erfindung ist es, die bekannten Vorrichtungen derart weiterzubilden, daß das drehbare Mittelteil in seiner Größe nicht von dem Freiraum zwischen den Holmen abhängig ist und unterschiedliche Schließkräfte von den beiden Spritzeinheiten auf das Mittelteil aufbringbar sind.task It is the object of the present invention to provide the known devices in such a way to further develop that rotatable middle part in its size not depends on the space between the bars and different Closing forces of the two injection units can be applied to the middle part.
Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Anspruchs 1 dadurch gelöst, dass in den verschieblichen Formaufspannplatten Holme als Zugstangen angeordnet sind, die freien Enden der Holme mittels Verriegelungselementen mit dem drehbaren Mittelteil oder mit den Holmen der gegenüberliegenden verschieblichen Formaufspannplatte verriegelbar sind.These This object is achieved in conjunction with the preamble of claim 1 solved, that in the sliding mold clamping plates spars as tie rods are arranged, the free ends of the spars by means of locking elements with the rotatable middle part or with the spars of the opposite movable platen are lockable.
Bei der vorgeschlagenen Lösung stützt sich weder das drehbare Mittelteil noch das feste Teilelement auf den Maschinenholmen ab. Durch die Verbindung zum Maschinenbett ist eine ausreichende Abstützung gewährleistet, wodurch es möglich wird, unterschiedliche Schließkräfte auf die beiden Werkzeuge, die den beiden Plastifizier- und Einspritzeinheiten zugeordnet sind, aufzubringen.at the proposed solution supports neither the rotatable middle part nor the fixed part element on from the machine spars. Through the connection to the machine bed is sufficient support guaranteed making it possible is, different closing forces the two tools, the two plasticizing and injection units are assigned to apply.
Weiterbildungsgemäß ist vorgesehen, daß an den verschieblichen Formaufspannplatten, die gemäß der Erfindung die Düsenplatten sind, Holme angeordnet sind, die als Zugstangen ausgelegt sind. Beim Öffnen der Formaufspannplatten fahren die Holme ebenfalls vom drehbaren Mittelteil weg, so daß dieses frei drehen kann. Die Holme greifen in Aussparungen im Mittelteil ein. In den Aussparungen sind Buchsen angeordnet, über die die Holme entweder mit dem Mittelteil oder aber auch mit den Holmen der gegenüberliegenden Formaufspannplatte verriegelt werden. Bei einer beidseitigen Ausführung mit 4 Holmen sind im ersten Fall 8 Buchsen und im zweiten Fall nur 4 Buchsen erforderlich.Training is provided, that on the sliding mold platens, according to the invention, the nozzle plates are, spars are arranged, which are designed as tie rods. When opening the Form platens drive the spars also from the rotatable middle section away, so this one can rotate freely. The spars reach into recesses in the middle section one. In the recesses bushings are arranged over the the spars either with the middle part or also with the spars of the opposite Lock platen are locked. With a two-sided execution with 4 bars are in the first case 8 bushes and in the second case only 4 Bushings required.
Als eine weitere Ausgestaltung kann das drehbare Mittelteil mit dem Maschinenbett verschraubt werden. Dies hat den Vorteil, dass an der beschriebenen Spritzgießvorrichtung beidseitig vom Mittelteil unterschiedliche Werkzeuge aufgespannt werden können. Dies entspricht dann der sogenannten Tandem-Spritzgießmaschine. Bei Verwendung von acht kurzhubigen Hydraulikzylindern sind sogar (im Gegensatz zu Tandem-Spritzgießmaschinen) unterschiedliche Zykluszeiten für beide Seiten realisierbar, wodurch ein sehr universeller Einsatz der Einrichtung möglich ist. Diese Anwendungen erfordern kein Drehen des Mittelteils, so dass eine Fixierung (durch Verschrauben oder einen Indexstift) sinnvoll sein kann.When a further embodiment, the rotatable central part with the Machine bed to be bolted. This has the advantage of being the described injection molding apparatus on both sides of the middle part different tools are clamped can. This then corresponds to the so-called tandem injection molding machine. When using eight short-stroke hydraulic cylinders, even (in Unlike tandem injection molding machines) different cycle times for Both sides realizable, which makes a very universal use the facility possible is. These applications do not require turning the middle section, so that a fixation (by screwing or an index pen) may be useful can.
An der verschieblichen Formaufspannplatte sind Mittel vorgesehen, über die eine Zugkraft auf die Holme aufgebracht werden kann. Hierbei werden kurzhubige Hydraulikzylinder, fälschlicher Weise oftmals auch Druckkissen genannt, bevorzugt. Wird eine Verriegelungsvariante gewählt, bei der die Holme mit den Holmen der gegenüberliegenden Formaufspannplatte verriegelt werden, entsteht quasi eine durchgehende Zugstange. Die Buchsen in dem Mittelteil müssen längsverschiebbar sein, damit der Einsatz der kurzhubigen Hydraulikzylinder auch in einer der Formaufspannplatten ausreichend ist. Die Zugkraft wird über die längsverschiebbare Buchse auf die andere Formaufspannplatte übertragen. In diesem Fall ist die Schließkraft beidseitig des Mittelteils gleich. Bei dieser Ausführung kann somit auf vier kurzhubige Hydraulikzylinder und auf vier Buchsen im Mittelteil verzichtet werden, wenn man den Einsatz von vier Holmen auf jeder Seite zugrunde legt. Alternativ können anstelle der drehbaren Buchsen querverschiebbare Verriegelungselemente, z.B. zwei Halbschalen mit Ringen, verwendet werden. Die Verriegelungselemente sind dann in der Platte quer zur Bewegungsrichtung verschiebbar.At the movable platen means are provided over the a tensile force can be applied to the spars. Here are short-stroke Hydraulic cylinder, wrong Way also often called pressure pad, preferably. Is a locking variant selected at the spars with the spars of the opposite platen be locked, creates a quasi-continuous drawbar. The Bushings in the middle part need longitudinally slidably so that the use of the short-stroke hydraulic cylinder also in one of the platens is sufficient. The pulling force is over the longitudinally movable Transfer socket to the other platen. In this case is the closing force on both sides of the middle part the same. In this embodiment can thus four short-stroke hydraulic cylinders and four bushings in the Middle part are dispensed with, if you use four spars on every page. Alternatively, instead of the rotatable Bushings transversely displaceable locking elements, e.g. two half-shells with rings, to be used. The locking elements are then slidable in the plate transversely to the direction of movement.
Fortbildungsgemäß wird vorgeschlagen, daß die verschieblichen Formaufspannplatten im Maschinenbett geführt werden. Sie sind über Mittel in der Höhe verstellbar, die Anpassung an unterschiedliche Werkzeugeinbauhöhen ist selbstverständlich ebenfalls vorgesehen. Hierdurch wird erreicht, daß die Formaufspannplatten an unterschiedliche Werkzeuge angepaßt und darauf abgestimmt werden können.Training is proposed that the slidable mold clamping plates are guided in the machine bed. They are over Means in height adjustable, the adaptation to different tool installation heights is Of course also provided. This ensures that the mold platens adapted to different tools and tuned to it can.
Um einen ausreichenden Freiraum zu erreichen ist vorgesehen, daß die Plastifizier- und Einspritzeinheit so an den verschieblichen Formauf spannplatten angeordnet ist, daß diese bei der Bewegung der Formaufspannplatte mitgeführt wird.In order to achieve sufficient space is provided that the plasticizing and A Injection unit is arranged on the slidable Formauf clamping plates, that this is carried along during the movement of the platen.
Vorteilhafterweise ist ein Drehantrieb für das drehbare Mittelteil unter diesem Mittelteil angeordnet und im Maschinenbett integriert. Über diesen Drehantrieb wird es ermöglicht, das Mittelteil um 360° zu drehen. Bevorzugt wird jedoch eine Drehung um 180°.advantageously, is a rotary drive for the rotatable central part arranged under this central part and in Machine bed integrated. about this rotary drive allows to turn the middle part 360 °. However, a rotation of 180 ° is preferred.
In einer Weiterbildung wird angeregt, daß eine dritte verschiebliche Formaufspannplatte mit einer daran angeordneten Plastifizier- und Einspritzeinheit vorzugsweise rechtwinklig zu den beiden ersten verschieblichen Formaufspannplatten angeordnet ist und ebenfalls auf das ortsfeste drehbare Mittelteil zubewegbar ist.In a further education is suggested that a third displaceable Platen with a plasticizing and arranged thereon Injection unit preferably perpendicular to the first two slidable platen is arranged and also is zubewegbar on the stationary rotatable central part.
Durch diese Fortbildung wird es ermöglicht, in den Prozeß einen weiteren Spritzvorgang zu integrieren. Dies kann eine andere Materialkomponente oder aber auch eine weitere Farbe sein.By this training will allow in the process one integrate further injection process. This may be another material component or but also be another color.
