Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Kunststoffkörpers aus mindestens drei Komponenten, mittels Formen, welche zwischen denselben zwei Formaufspannplatten so angeordnet sind, daß jeweils mindestens eine von zwei korrespondierenden Formhälften ortsfest ist, wobei zwei Komponenten in gesonderten Formen hergestellt und anschließend in einem gemeinsamen Formhohlraum mit der dritten Komponente umspritzt werden. The invention relates to a method for producing a plastic body at least three components, by means of shapes which are between the same two Platen are arranged so that at least one of two corresponding ones Mold halves is stationary, with two components made in separate molds and then encapsulated in a common mold cavity with the third component become.
Bei der Herstellung von Kunststoffkörpern aus mindestens drei Komponenten werden üblicherweise zwei verschiedene Spritzgießmaschinen verwendet. Es wurde aber auch schon vorgeschlagen, zwei Formen mit gemeinsamer Formtrennebene so zu verwenden, daß zunächst gleichzeitig zwei Komponenten hergestellt werden, woraufhin der Formhohlraum, der zur Herstellung einer Komponente gedient hat, durch Schieber, Kernzüge oder dergleichen so verändert wird, daß die zweite Komponente in den veränderten Hohlraum eingebracht und dort gemeinsam mit der ersten Komponente mit der dritten Komponente umspritzt werden kann. When manufacturing plastic bodies from at least three components Usually two different injection molding machines are used. But it was too already suggested using two molds with a common mold parting plane that first two components are produced simultaneously, whereupon the Mold cavity that was used to manufacture a component, by slides, core pulls or The like is changed so that the second component in the changed cavity introduced and there together with the first component with the third component can be encapsulated.
Das geschilderte Verfahren beschränkt die Gestaltungsmöglichkeiten, da Veränderungen einer Formkavität konstruktiv nicht beliebig vorgenommen werden können. The described method limits the design options, since changes a mold cavity cannot be made arbitrarily.
Die Erfindung erweitert den Gestaltungsspielraum bei der Herstellung mehrkomponentiger Kunststoffkörper, in dem vorgesehen wird, daß die den gemeinsamen Formhohlraum bildende Form gegenüber den beiden gesonderten Formen in Richtung der Formtrennebene versetzt angeordnet ist. The invention extends the design freedom in the production of multi-component Plastic body in which it is provided that the common mold cavity forming form compared to the two separate forms in the direction of the mold parting plane is staggered.
Im einfachsten Fall wird die Erfindung dadurch verkörpert, daß die den gemeinsamen Formhohlraum bildende Form durch eine verschwenkbare Formhälfte, einer der beiden gesonderten Formen Und eine feststehende Matrize gebildet ist und eine Komponente mit einem Handhabungsgerät oder von Hand in diese verschwenkbare Formhälfte einsetzbar ist. Hier bleibt also eine der beiden zuerst gespritzten Komponenten mit einer der zu ihrer Herstellung dienenden Formhälfte verbunden und wird lediglich mittels eines Drehtisches oder einer Indexplatte vor eine feststehende, mit dieser Formhälfte zusammenpassende Matrize verschwenkt. In the simplest case, the invention is embodied in that the common Mold cavity forming mold by a pivotable mold half, one of the two separate forms And a fixed die is formed and a component with a handling device or by hand in this pivotable mold half. So here one of the two components injected first remains with one of theirs Manufacturing serving mold half connected and is only by means of a turntable or an index plate in front of a fixed one that matches this mold half Matrix swiveled.
Konstruktiv einfacher ist es, nicht das Umsetzen mittels Handlinggerät und das Verschwenken mittels Drehtisch zu kombinieren, sondern bereits zunächst unabhängig voneinander gespritzte Komponenten in eine unabhängige dritte Form zu übertragen und dort zu umspritzen. It is structurally simpler, not the implementation using a handling device and that Combine pivoting using a rotary table, but initially independently components injected from each other into an independent third form and there overmolded.
Einzelheiten der Erfindung werden anschließend anhand der Zeichnungen erläutert. Details of the invention are subsequently explained with reference to the drawings.
In diesen stellen die Fig. 1 bis 3 den Verfahrensablauf anhand einer Stirnansicht auf einem Drehtisch montierter Formhälften dar; In these Figures 1 to 3 represent the process sequence with reference to a front view of a turntable mounted mold halves is.
Fig. 4 ist die zugehörige schematische Ansicht in die geöffnete Form von oben; Fig. 4 is the associated schematic view in the opened form from above;
Fig. 5 entspricht Fig. 4 für ein zweites Ausführungsbeispiel. Fig. 5 corresponds to Fig. 4 for a second embodiment.
Bei Durchführung des erfindungsgemäßen Verfahrens in seiner ersten Variante wird zunächst in Formen 1, 1' und 2, 2' (vergleiche Fig. 4, Fig. 1) je eine von zwei Komponenten 21 bzw. 22 gespritzt. Diese können sich hinsichtlich Material und Färbung unterscheiden. Anschießend wird der Drehtisch 10, welcher die Formaufspannplatte 7 trägt, um die Längsmittelachse 13 der Maschine geschwenkt, wodurch die darauf befestigten Formhälften 1, 2 und 11, 12 ihre Position vertauschen. Die Komponente 21 gelangt durch die Verschwenkung in die aus Fig. 2 ersichtliche Lage. Vor oder nach der Verschwenkung wird die Komponente 22 in die Komponente 21 eingesetzt. Die Formhälfte 1 befindet sich nun gegenüber einer auf der feststehenden Formaufspannplatte befestigten Formhälfte 3'. Anschließend wird die bewegliche Formaufspannplatte 7 an die Trennebene 9 herangeführt und die Formen geschlossen, woraufhin in dem aus den Formhälften 1 und 3' gebildeten gemeinsamen Formhohlraum das aus Fig. 3 ersichtliche fertige Produkt gebildet wird. Gleichzeitig werden in den Formhälften 11, 12 neue Einzelkomponenten 21', 22' gebildet, womit ein neuer Zyklus beginnen kann. When the first variant of the method according to the invention is carried out, one of two components 21 and 22 is injected into molds 1 , 1 'and 2 , 2 ' (see FIG. 4, FIG. 1). These can differ in terms of material and color. The turntable 10 , which carries the platen 7, is then pivoted about the longitudinal central axis 13 of the machine, as a result of which the mold halves 1 , 2 and 11 , 12 exchange their position. The component 21 reaches the position shown in FIG. 2 by the pivoting. Before or after the pivoting, component 22 is inserted into component 21 . The mold half 1 is now opposite a mold half 3 'fastened on the fixed platen. The movable platen 7 is then brought up to the parting plane 9 and the molds are closed, whereupon the finished product shown in FIG. 3 is formed in the common mold cavity formed from the mold halves 1 and 3 '. At the same time, new individual components 21 ', 22 ' are formed in the mold halves 11 , 12 , with which a new cycle can begin.
Die einer Formaufspannplatte zugeordneten Formhälften 1, 2, 11, 12 bzw. 1', 2', 3' können jeweils aus einer gemeinsamen Platte herausgearbeitet sein. The mold halves 1 , 2 , 11 , 12 or 1 ', 2 ', 3 'assigned to a platen can each be machined from a common plate.
Die in Fig. 5 schematisch skizzierte Ausführungsvariante ist konstruktiv besonders einfach, als sie ohne Drehtisch auskommt. Überdies sind bei dieser Variante jeweils alle Formhälften im Einsatz, wogegen beim ersten Ausführungsbeispiel nach Fig. 1 bis 4 die Formhälften 2 und 12 nur abwechselnd benötigt werden. Wie beim beschriebenen Ausführungsbeispiel werden bei der Einrichtung nach Fig. 5 gesonderte Komponenten in den Formen 1, 1' und 2, 2' hergestellt. Anschließend werden jedoch beide Komponenten in eine der Formhälften 3, 3' übertragen und dort mit Kunststoff umspritzt, welcher wiederum hinsichtlich Art und Farbe bezüglich der ersten beiden Komponenten unterschiedlich sein kann. The embodiment variant schematically outlined in FIG. 5 is structurally particularly simple when it does not require a rotary table. In addition, in this variant all mold halves are used, whereas in the first embodiment according to FIGS. 1 to 4 the mold halves 2 and 12 are only required alternately. As in the exemplary embodiment described, separate components in the forms 1 , 1 'and 2 , 2 ' are produced in the device according to FIG . Subsequently, however, both components are transferred into one of the mold halves 3 , 3 'and overmolded there with plastic, which in turn can be different in terms of type and color with respect to the first two components.
