Description

Verfahren zur Herstellung von Formgegenständen aus thermoplastischen Kunststoffen mit artgleichem Folienüberzug Es ist bereits llekannt. Kunststoffteile, wie z. B.Process for the production of molded articles from thermoplastic Plastics with a film of the same type. It is already not recognized. Plastic parts, such as B.

Satteldecken für Fahrräder oder Motorräder, in der Weise herzustellen, daß der auf Fließtemperatur erwärmte thermoplastische Kunststoff nach dem Schlagpreßvcrfahrell in einer Preßform in die gewünschte Gestalt gebracht wird. In vielen Fällen, wie z.U. bei den erwähnten Satteldecken, ist es notwendig, diese nachträglich mit einer nahtlosen Bedeckung aus kunstleder o. dgl. zu überziehen, um einer Satteldecke aus verhältnismäßig billigem Material einen überzug von hoher Verschleißfestigkeit und ansprechendem Aussehen bei einer gewissen Glätte zu geben. Dieses nachträgliche Überziehen von Kunststoffteilen mit Kunstleder o. dgl. ist, da es einen besonderen Arbeitsgang erfordert, zeitraubend und kostspielig.Saddlecloths for bicycles or motorcycles, manufactured in such a way that that the thermoplastic material heated to flow temperature according to the Schlagpreßvcrfahrell is brought into the desired shape in a mold. In many cases, like to. With the mentioned saddlecloths, it is necessary to add a seamless cover made of synthetic leather or the like. To cover a saddlecloth from relatively cheap material a coating of high wear resistance and to give an attractive appearance with a certain smoothness. This subsequent Covering plastic parts with synthetic leather o. The like. Is, because it is a special Required, time consuming and costly operation.

Der Erfindung liegt die Aufgabe zugrunde, diesen besonderen Arbeitsgang zu ersparen, ohne die Giite des zur Verwendung kommenden Verbundkörpers gegenüber den bisher in zwei Arbeitsgängen hergestellten Erzeugnissen zu vermindern. The invention is based on the object of this particular operation to save, without the Giite of the composite body to be used opposite to reduce the products previously manufactured in two operations.

L)ies wird erfindungsgemäß durch ein Verfahren erreicht, bei dem, wie an sich bekannt, erwärmter therinoplastischer Kunststoff unter Druck in einem Verformungswerkzeug geformt wird, bei dem aber in diesem im Gegensatz zu den bekannten Verfahren nicht nur die Verformung des Kunststoffes stattfindet sondern auch die Aufbringung der Folie aus thermoplastischem Kunststoff in ein und demselben Arbeitgang erfolgt.L) ies is achieved according to the invention by a method in which, as is known per se, heated therinoplastic plastic under pressure in one Deformation tool is shaped, but in this in contrast to the known Not only the deformation of the plastic takes place but also the process Application of the thermoplastic film in one and the same operation he follows.

Das Verfahren kann in verschiedener Weise durchgeführt werden. Wesentlich ist dahei, daß die aufzubringende Folie vor und/oder bei der Verformung des Kunststoffes in gespanntem Zustande gehalten wird, damit ein glattes Anliegen und ein gutes Anhaften der Folie an dem Kunststoffteil erzielt wird. l3ei einem der eriindungsgemäßen Verfahren wird die Folie in dem Raum zwischen den beiden Teilen des Preßwerkzeuges ausgespannt und der auf die Verformungstemperatur, z. B. auf die Fließtemperatur oder auch nur auf eine über dem Erstarrungspunkt liegende Temperatur außerhalb des Werkzeuges gebrachte Kunststoff in das Werkzeug unter die Folie eingelegt und unter der MTirkung eines Preßvorgangs verformt. Dabei nimmt der warme Kunststoff die genaue Form des Innenraums des Werkzeuges an, während die Folie auf die Oberseite des sich in der Presse ausbildenden Kunststoffteils aufgepreßt wird. Als geeigneter Stoff für den Kunststoffteil kann z. B. Polyvinylchlorid oder auch ein thermoplastisches Mischpolymerisat dienen und als Folie z.B. der Warenschutz genießende Kunststoff Mipolam, der chemisch ein Mischpolymerisat von Vinylchlorid und Akrylsäureestern darstellt. Die Folie verbindet sich bei dem l'reßvorgang fest mit dem Kunststoffteil. The method can be carried out in a number of ways. Essential is because that the film to be applied before and / or during the deformation of the plastic is kept in a tense condition, so that a smooth application and a good adherence the film is achieved on the plastic part. l3in one of the methods according to the invention will the film in the space between the two parts of the pressing tool unclamped and the deformation temperature, z. B. on the flow temperature or just to a temperature above the freezing point outside of the Tool brought plastic inserted into the tool under the film and under deformed by the action of a pressing process. In doing so, the warm plastic takes the exact Shape the interior of the tool while the slide is on top of the itself in the press forming plastic part is pressed. As a suitable substance for the plastic part can, for. B. polyvinyl chloride or a thermoplastic Mixed polymer are used and as a film, e.g. plastic that benefits from product protection Mipolam, the chemically mixed polymer of vinyl chloride and acrylic acid esters represents. The foil bonds firmly to the plastic part during the ressection process.

Ein anderes Verfahren zur Verformung des Kunststoffs und zur gleichzeitigen Aufbringung einer Folie auf der Oberfläche des Kunststoffteiles besteht darin, daß die Folie in das Werkzeug mit einer gewissen Vorspannung eingelegt wird, worauf die Form geschlossen und der Kunststoff, der außerhalb des Werkzeugs auf Fließtemperatur erhitzt wurde, wie an sich üblich, durch einen Einspritzkanal, am Werkzeug in die Form eingespritzt wird. Hierbei wird infolge des Eindringens des Kunststoffs in den Hohlraum der Werkzeugform die Folie an die Wandung des vorzugsweise kalten Spritzwerkzeugs gedrückt und so vor einem übermäßigen Erweichen geschützt. Nach Vollendung des Spritzvorganges und Erkalten der Kunststoffmassc liegt die Folie iest auf dem erkalteten Kunststoffkörper auf. Another method of deforming the plastic and at the same time Application of a film on the surface of the plastic part consists in that the film is inserted into the tool with a certain pretension, whereupon the mold is closed and the plastic, which is outside the mold, is at flow temperature was heated, as usual, through an injection channel, on the tool into the Mold is injected. This is due to the penetration of the plastic in the cavity of the mold, the film on the wall of the preferably cold injection mold pressed and thus protected from excessive softening. After completion of the spraying process and the plastic compound cools, the film lies on the cooled plastic body on.

Um ein sicheres Haften der Folie an dem Kunststoffpreßteil zu erreichen, kann insbesondere bei Verwendung von Kunststoffen, die nicht gut miteinander binden, die Folie vor dem Einlegen einseitig mit einem Klebstoff bestrichen werden, z. B. einem Polyvinylchloridkleber, wodurch ein festes l-laften der Folie erzielt wird. In order to ensure that the film adheres securely to the molded plastic part, especially when using plastics that do not bond well to one another, the film can be coated on one side with an adhesive before inserting it, e.g. B. a polyvinyl chloride adhesive, which ensures that the film adheres firmly.

Bei der Herstellung gewölbter Preßkörper ist es licht unbedingt erforderlich, der Folie beim Einlegen eine Spannung zu erteilen, da hier beim Schließen des Werkzeuges die Anspannung der Folie infolge der Wölbung des unteren Teiles des Preßwerkzeuges von selbst erfolgt. When producing arched pressed bodies, it is absolutely necessary to to give tension to the film when it is inserted, since this is when the mold is closed the tension of the film due to the curvature of the lower part of the pressing tool happens by itself.

Es ist auch bei Verarbeitung von bei Normaltemperatur hartem thermoplastischem Kunststoff meist entbehrlich, bei dem beschriebenen Preßverfahren eine Vorwärmung des Kunststoffes auf seine Fließtemperatur vorzunehmen; vielmehr genügt iii den meisten Fällen eine Erwärmung über den Erstarrungspunkt, wobei der Kunststoff eine weiche gummiartige Beschaffenheit annimmt. In dieser Form läßt er sich gut verpressen und erstarrt dann iii der Form zu einem dieser genau entsprechenden Kunststoffteil. It is also used when processing thermoplastics that are hard at normal temperature Plastic can usually be dispensed with, and preheating is required in the pressing process described make the plastic to its flow temperature; rather, iii suffices In most cases a heating above the freezing point, whereby the plastic a takes on a soft rubbery texture. In this form it can be pressed easily and then solidifies iii the shape to form a plastic part that exactly corresponds to this.

Per Gegenstand der Erfindung ist in den Fig. I >5 6 iii beispielsweisen Ausführungsformen dargestellt. Es zeigt Fig. I eine Spritzeinrichtung für Kunststoffe mit in das Verformungswerkzeug eingelegter Folie im Längsschnitt. The subject matter of the invention is shown in FIGS. I> 5 6 iii by way of example Embodiments shown. It shows Fig. I a spray device for plastics with the film inserted in the forming tool in a longitudinal section.

Fig. 2 das gleiche. jedoch nach erfolgtem Spritzvorgang. Fig. 2 is the same. however, after the spraying process has taken place.

Fit. 3 ein Preßwerkzeng mit eingelegtem Kunststoff und darüberliegender Folie im Lngsschnitt, Fig. 4 das gleiche nach erfolgter Pressung, Fig. 5 eine gespritzte bzw. gepreßte Satteldecke als Schaubild, Fig. 6 einen Schnitt nach der Linie VI-VI der Fig. 5 in vergrößertem Maßstab. Fit. 3 a press tool with inserted plastic and overlying it Film in longitudinal section, FIG. 4 the same after pressing, FIG. 5 an injection-molded one or pressed saddlecloth as a diagram, FIG. 6 shows a section along the line VI-VI of Fig. 5 on an enlarged scale.

Bei der in Fig. 1 dal-gestellten Spritzeinrichtung ist zwischen die hciden Werkzeugteile l und 2 die Kunststoffolie 3 eingelegt. die von einem Spannrahmen 4 festgehalten wird. 1 )er Kunststoffvorrat 7 befindet sich in dem Zylinder 5 auf einer für das Spritzen geeigneten Temperatur. When in Fig. 1 dal-provided spray device is between the The plastic film 3 is inserted into the tool parts 1 and 2. those of a stenter frame 4 is recorded. 1) the plastic supply 7 is located in the cylinder 5 a temperature suitable for spraying.

Bei der Ausübung eines Druckes auf den Preßstempel wird der weiche Kunststoff durch den Spritzkanal X in die geschlossene Preßform 1, 2 gedrückt. Dabei weicht die Folie 3 aus und legt sich an die Innenfläche des Werkzeugteiles 2 an. When a pressure is exerted on the ram, the soft one Plastic pressed through the injection channel X into the closed mold 1, 2. Included the film 3 gives way and lies against the inner surface of the tool part 2.

Infolge der erhöhten Temperatur der in die PreB-form gespritzten Kunststoffmasse 7 tritt eine innige Verbindung zwischen der Kunststoffmasse und der Folie eiii. Nach dem Erkalten kann der gespritzte Kunststoffteil <ler Form entnommen werden, der nunmehr ein Verbundstück v< >10 Kunststoffmasse und Folie hildet (Fig. 2).As a result of the increased temperature of the plastic mass injected into the PreB mold 7 there is an intimate connection between the plastic compound and the film eiii. After cooling down, the injection-molded plastic part can be removed from the mold, which now forms a composite piece v <> 10 plastic compound and film (Fig. 2).

In den Fig. 3 und 4 ist eine linrichtung dargestellt, bei der die Verformung des Kunststoffes und die Verbindung der Folie gleichfalls in einem Arbeitsgang im Formmest des aus den Teilen I und 2 bestehenden Preßwerkzeugs erfolgen. Die Kunststoffmasse 7 ist in einem zur Pressung plastischein Zustand auf den Werkzeugteil 2 aufgebracht. 3 and 4, a linrichtung is shown in which the Deformation of the plastic and the connection of the film also in one operation take place in the form of the pressing tool consisting of parts I and 2. The plastic mass 7 is applied to the tool part 2 in a plastic condition for pressing.

Darüber ist die Folie 3 ausgespannt, die auf einem Ring 9 aufliegt, der durch Federn 10 in solcher Höhe gehalten wird, daß die über ihm liegende Folie 3 den Kunststoff nicht berührt. Nach dem Niedergang des Stempels hat sich der Kunststoff 7 in dem Hohlraum der Form 1 2 ausgebreitet. Die Folie 3 ist alsdann fest mit dem Kunststoffteil7 verbunden. Die feste Verbindung kann durch Aufbringen eines Klebstoffes auf die Oberfläche der Folie verbessert bzw. erleichtert werden.The film 3 is stretched over it and rests on a ring 9, which is held by springs 10 at such a height that the film overlying it 3 does not touch the plastic. After the die went down, the plastic was broken 7 spread out in the cavity of the mold 1 2. The film 3 is then fixed to the Plastic part7 connected. The fixed connection can be achieved by applying an adhesive can be improved or facilitated on the surface of the film.

Die bei dem Spritz- bzw. Preßvorgang zu wählenden Temperaturen für die j>reßmasse und für die Preßform sind dem Fachmann geläufige Maßnahmen. In der Regel bedarf es einer besonderen Beheizung der Preßform nicht, da dieser die erforderliche Wärme von tlem Preßstoff selbst zugeführt wird. The temperatures to be selected for the injection or pressing process the molding compound and for the compression mold are measures familiar to the person skilled in the art. In As a rule, there is no need for a special heating of the mold, as this the required heat is supplied from tlem pressed material itself.

Häufig ist sogar eine Kühlung der Preßform notwendig, da das verarbeitete Material in der Form abkühlt und die in ilim enthaltene Wärme an die Form abgibt, von der sie durch geeignete Kühlmaßnahmen abgeführt wird. Often even a cooling of the mold is necessary because the processed The material cools down in the mold and the heat contained in the ilim is transferred to the mold, from which it is removed by suitable cooling measures.
