Verfahren zur Herstellung eines Gegenstandes aus Kunststoff, an dem wenigstens eine in einem Spritzgußwerkzeug geformte Flache mit Metall bedeckt ist.Process for the production of an article from plastic, on which at least one in an injection molding tool shaped surface is covered with metal.
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Gegenstandes aus Kunststoff, an dem wenigstens eine in einem Spritzgußwerkzeug geformte Fläche mit Metall bedeckt ist.The invention relates to a method for producing an object made of plastic, on which at least one surface formed in an injection mold is covered with metal.
Bei der Herstellung von Kunststoffgegenständen in Spritzgußwerkzeugen entstehen normalerweise Unebenheiten an solchen Stellen der Oberfläche, an denen die Materialdicke größer ist als an den übrigen Stellen des Gegenstandes. Dies beruht darauf, daß beim Erstarren oder Aushärten des Kunststoffes infolge der dabei auftretenden MaterialSchrumpfungen eingefallene Stellen auftreten. Bei den meisten Gegenständen können solche Unebenheiten und evtl. andere auftretenden Oberflächenfehler hingenommen werden. In besonderen Fällen stellt man an die Oberflächenqualität des Gegenstandes höhere Ansprüche. Dies giltIn the manufacture of plastic objects in injection molding tools Usually, unevenness occurs at those points on the surface where the material thickness is greater than in the other parts of the object. This is due to the fact that when the plastic solidifies or hardens as a result of material shrinkage occurring in the process appear. With most objects such unevenness and possibly other surface defects can be accepted will. In special cases, higher demands are placed on the surface quality of the object. this applies

speziell für Gegenstände mit größeren Oberflächen, wo hohe Ansprüche an das Aussehen gestellt werden, wie beispielsweise bei Oberflächen von Kühlschränken, Spülbänken, Badewannen, gewissen Autoteilen und ähnlichen Gegenständen. Das Problem, gleichmäßige Oberflächen zu erhalten, ist größer bei Gegenständen mit größeren Oberflächen, und zwar u.a. deshalb, weil man bei ihnen normalerweise gezvmngen ist, sie mit dickeren, rippenähnlichen Partien auf der Rückseite zu versehen, um ihnen die erforderliehe Steifigkeit zu geben. Bei gewissen Kunststoffen besteht außerdem das Problem, eine gute Haftung zwischen der Oberfläche des Gegenstandes und der hierauf angebrachten Lackschicht zu erhalten.especially for objects with larger surfaces, where high Demands on the appearance are made, such as for the surfaces of refrigerators, sinks, bathtubs, certain Auto parts and similar items. The problem of obtaining uniform surfaces is greater with objects with larger surfaces, among other things because one is normally forced to use them with thicker, to provide rib-like sections on the back to give them the required rigidity. With certain Plastics also have the problem of good adhesion between the surface of the object and that attached to it To obtain a layer of varnish.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu entwickeln, bei der die Oberfläche auch größerer herzustellender Gegenstände eine sehr saubere und gleichmäßige Beschaffenheit hat.The present invention is based on the object To develop a method of the type mentioned, in which the surface of larger objects to be produced a has a very clean and uniform texture.
Zur Lösung dieser Aufgabe wird ein Verfahren der eingangs genannten Art vorgeschlagen, welches die im kennzeichnenden Teil des Anspruches 1 genannten Merkmale aufweist.To solve this problem, a method of the type mentioned is proposed, which in the characterizing Part of claim 1 has mentioned features.
Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind in den Unteransprüchen genannt.Advantageous refinements of the method according to the invention are specified in the subclaims.
Die Einklemmung des Bandes des Metallbleches zwischen den Werkzeughälften ist Voraussetzung dafür, daß Metallbleche von genügender Festigkeit für die Herstellung des Kunststoffgegen-The jamming of the strip of sheet metal between the tool halves is a prerequisite that metal sheets of sufficient strength for the production of the plastic counter-

Standes verwendet werden können.Stand can be used.
Die Erfindung ist besonders geeignet für die Herstellung von Kunststoffgegenständen -mit großer Oberfläche, wie sieThe invention is particularly suitable for the production of plastic objects - with a large surface area, like them
2 z.B. bei Gegenständen mit einer Oberfläche von mehr als 0,5 m vorkommen.2 e.g. occur in objects with a surface of more than 0.5 m.
Die Dicke des Bleches ist geringer als die des Kunststoffmaterials. Vorzugsweise liegt die Dicke des Bleches in dem Bereich von 0,1 - 1,5 mm. Speziell wird der Bereich von 0,2 - 0,7 mm verwendet. Es ist auch möglich, Metallfolien anzuwenden, und im Sinne der Erfindung soll unter den Begriff "dünnes Metallblech" auch eine Folie fallen.The thickness of the sheet is less than that of the plastic material. The thickness of the sheet is preferably in the range from 0.1 to 1.5 mm. The area of 0.2-0.7 mm used. It is also possible to use metal foils, and for the purposes of the invention, the term "thin metal sheet" also covered a slide.
Das Metallblech wird zweckmäßigerweise in Form einer ebenen Scheibe zwischen den Werkzeughälften-angebracht. Der Druck, mit dem der Kunststoff in das Spritzgußwerkzeug gedrückt wird, muß ausreichen, das Blech derart zu verformen, daß es sich dicht an die Innenwand der Form anlegt, wo es am Kunststoff des Fertigproduktes fixiert werden soll. Es ist auch möglich, das Blech vorzuformen, gegebenenfalls zu der annähernd endgültigen Form, die es auf dem Kunststoffgegenstand einnehmen soll. Zu diesem Zweck kann das Blech in einem geeigneten getrennten Preßwerkzeug gepreßt werden, bevor es »wischen die Werkzeughälften gelegt wird. Es ist jedoch für die Lösung der der Erfindung zugrunde liegenden Aufgabe wesentlich, daß die endgültige Formung des Metallblechee in Verbindung mit dem Formen des Kunststoffes in dem Formwerkzeug erfolgt.The sheet metal is expediently attached in the form of a flat disk between the tool halves. The pressure with which the plastic is pressed into the injection molding tool must be sufficient to deform the sheet metal in such a way that it rests tightly against the inner wall of the mold where it is to be fixed to the plastic of the finished product. It is also possible to preform the sheet metal, if necessary to the approximately final shape that it is to assume on the plastic object. For this purpose the sheet metal can be pressed in a suitable separate pressing tool before it is placed between the tool halves. However, it is essential for achieving the object on which the invention is based that the final shaping of the sheet metal takes place in connection with the shaping of the plastic in the shaping tool.

Als Metall für das Blech wird in erster Linie Aluminium verwendet, das in Blechform leicht erhältlich und verhältnismäßig billig ist sowie eine geringe Dichte hat. Jedoch sind auch andere Metalle verwendbar, wie z.B. ötahl^Cupfer oder Messing.The main metal used for the sheet metal is aluminum is used, which is readily available in sheet metal form, is relatively inexpensive and has a low density. However other metals can also be used, such as ötahl ^ cupfer or brass.
Der Kunststoff kann ein Thermoplast sein, der im Formwerkzeug erstarrt, wie u.a. Polypropen, Polyäthylen, Polyamid, ein Mischpolymer aus Acrylnitril, Butadien und Styren (ABS), Polycarbonat, Polyuretan, Polyvinylchlorid, Polyäthylenterephtalat, Polybutylenterephtalat, Polymethylmetakrylat, Polysulfon, Polyphenylenoxyd, Polymonochlortrifluoräthylen und Polyazetal. Vorzugsweise wird Polypropen verwendet. Der iüinst stoff kann auch ein härtbarer Kunststoff sein, der im Formwerkzeug härtet, wie beispielsweise ein ungesättigtes Polyesterharz, ein Äthoxylinharz, ein Melaminharz und ein Fenolharz.The plastic can be a thermoplastic that solidifies in the mold, such as polypropene, polyethylene, polyamide, among others Mixed polymer of acrylonitrile, butadiene and styrene (ABS), polycarbonate, polyurethane, polyvinyl chloride, polyethylene terephthalate, Polybutylene terephthalate, polymethyl methacrylate, polysulfone, Polyphenylene oxide, polymonochlorotrifluoroethylene and polyacetal. Polypropene is preferably used. The iüinst substance can also be a hardenable plastic that hardens in the mold, such as an unsaturated polyester resin, an ethoxylin resin, a melamine resin and a fenol resin.
Der Kunststoff, egal ob Thermoplast oder härtbarer Kunststoff, enthält normalerweise herkömmliche pulverförmige und faserige Füllmittel, wie z.B. Talk, Steinmehl, Holzmehl und Glimmermehl bzw. Glasfaser, Baumwollfaser und Asbestfaser. Außerdem enthält der Kunststoff normalerweise verschiedene Zusätze konventioneller Art, um ihm spezielle Eigenschaften zu geben, wie z.B. Pigment und Farbstoffe zum Färben des Formstückes, Antioxydante, Zusätze zur Erhöhung der Feuerfestigkeit usw.The plastic, whether thermoplastic or hardenable plastic, usually contains conventional powdery and fibrous Fillers, such as talc, stone flour, wood flour and mica flour or glass fiber, cotton fiber and asbestos fiber. aside from that the plastic usually contains various conventional additives to give it special properties, such as pigments and dyes for coloring the molding, antioxidants, additives to increase the fire resistance, etc.

Für thermoplaste wird die Temperatur im Vferkzeug normalerweise zwischen Zimmertemperatur und 15O0C gehalten, und die Zeit für das Formen bewegt sich zwischen einigen Sekunden bis zu einigen Ilinuten. Für härtbare Kunststoffe wird die Temperatur im Werkzeug normalerweise zwischen 10O0C und 200 C gehalten, und die Zeit für das Formen liegt in dem eben für Thermoplaste angerebenen Bereich.Apply pressure of 10 - 100 MN / m in the mold cavity. For thermoplastics, the temperature is normally held in Vferkzeug between room temperature and 15O 0 C, and the time for molding ranges from a few seconds up to a few Ilinuten. For thermosetting plastics, the temperature is normally held in the tool between 10O 0 C and 200 C, and the time for forming is in the anger flat plane area for thermoplastics.
Pur gewisse Materialkombinationen von Metallblech und Kunststoff kann es zweckmäßig sein, spezielle Maßnahmen zur Verbesserung der Haftung zwischen Metall und Kunststoff vorzusehen. Eine solche Maßnahme besteht darin, vor dem Einlegen des Bleches in das Spritzwerkzeug auf dem Blech einen Film aus Kunststoff zu verankern, beispielsweise durch Festleimen des Kunststoff ilmes an der Seite des Bleches, die dem zu spritzenden Kunststoff zugewendet werden soll. Dabei ist es oft zweckmäßig, für den Film denselben Kunststoff zu verwenden, aus dem der Kunststoffgegenstand gespritzt werden soll.For certain material combinations of sheet metal and plastic, it can be useful to take special measures for improvement the adhesion between metal and plastic. One Such a measure consists in placing a plastic film on the metal sheet before placing the metal sheet in the injection molding tool to anchor, for example by gluing the plastic ilmes on the side of the sheet metal that is to be sprayed Plastic should be turned to. It is often useful to use the same plastic for the film which the plastic object is to be injected.
Für bestimmte Gegenstände wird nicht nur eine gute Oberflächenbeschaffenheit auf der einen Seite der Kunststoff-wand, normalerweise der Vorderseite, verlangt, sondern auf beiden Seiten. Um dies mit dem Verfahren nach der Erfindung zu erreichen, wird vor dem Schließen der Form ein zweites dünnes MetallblechFor certain objects a good surface finish is not the only thing on one side of the plastic wall, usually the front, requested, but on both sides. To achieve this with the method according to the invention, a second thin sheet of metal is placed before the mold is closed

In der unteren Werkzeughälfte ist ein Einspritzkanal 3 für den Kunststoff angeordnet. In geschlossenem Zustand "bilden die Werkzeughälften einen haubenförmigen Pormhohlraum 4. Die Querschnittsebene A am Werkzeug, senkrecht zur Bewegungsrichtung der unteren Werkzeughälfte, wird Werkzeugteilung genannt.In the lower mold half there is an injection channel 3 arranged for the plastic. When closed "form the tool halves a hood-shaped Pormhohlraum 4. Die Cross-sectional plane A on the tool, perpendicular to the direction of movement of the lower tool half, is called the tool division.
Die Herstellung eines Gegenstandes gemäß der Erfindung kann auf folgende Weise vor sich gehen: Ein Blech 5, beispielsweise eine ebene Scheibe aus Aluminium mit einer Dicke von 0,5 mm, wird zwischen die beiden Werkseughälften gelegt, wobei das Werkzeug offen ist, wie es aus Pig. 1a ersichtlich ist. Die nach unten gewendete Seite des Bleches ist mit einem Film aus Polypropen überzogen, der mit einem iithoxylinharzleim an das Blech fixiert ist. Das Werkzeugteil 2b wird dann nach oben bewegt und klemmt den Hand 6 des Bleches zwischen sich und dem Werkzeugteil 1b fest. Danach wird-das Y/erkzeugteil 2a nach oben bewegt, was zu einer streckenden Verformung des Bleches führt, wie sie aus Pig. 1b hervorgeht. Ein Kunststoff, bestehend aus Polypropen mit einer Temperatur von 27O0C, d.h. in geschmolzenem Zustand, wird durch den Einspritzkanal 3, wie Pig. 1c zeigt, in das Werkzeug, das eine Temperatur von 50 C hat, eingespritzt. Der Druck im Pormhohlraum beträgtThe manufacture of an object according to the invention can take place in the following way: A sheet 5, for example a flat disc made of aluminum with a thickness of 0.5 mm, is placed between the two halves of the factory, the tool being open as it is from Pig. 1a can be seen. The downward facing side of the sheet is covered with a film of polypropene, which is fixed to the sheet with an iithoxylin resin glue. The tool part 2b is then moved upwards and clamps the hand 6 of the sheet between itself and the tool part 1b. Thereafter, the Y / tool part 2a is moved upwards, which leads to a stretching deformation of the sheet metal, as shown in Pig. 1b. A plastic, consisting of polypropene having a temperature of 27O 0 C, that is in a molten state, through the injection channel 3, as Pig. 1c shows, injected into the tool, which has a temperature of 50 ° C. The pressure in the Pormhohlraum is

Der Blechrand 6 wird dann entfernt, beispielsweise indem man ihn abschneidet.V / tool is opened, as can be seen from Fig. 1d, and the finished plastic object, the top of which is made of lietallblech is covered, can be removed from the tool. The sheet metal edge 6 is then removed, for example by cutting it off.
Die Herstellung erfolgt entsprechend bei der Verwendung eines anderen Thermoplastes oder bei der Verwendung eines härtbaren Kunststoffes bzw. bei der Benutzung eines Bleches aus einem anderen Metall.Production takes place accordingly when using a different thermoplastic or when using a curable one Plastic or when using a sheet made of a different metal.
Wenn Metallbleche an zwei gegenüberliegenden Seiten eines Gegenstandes verankert werden sollen, kann dies ähnlich erfolgen wie eben anhand der Figuren 1a - 1b beschrieben wurde, wobei jedoch folgende Modifikationen vorzunehmen sind: Jiin zweites Blech 7 der gleichen Art wie das Blech 5, bei eiern die J^olypropenschicht zum Formhohlraum hingewendet ist, wird auf der unteren Werkzeughälfte aufgebracht, wie aus Fig. 2a hervorgeht. Der Einspritzkanal wird zwischen den Blechen 5 und 7 angeordnet, beispielsweise über ein abnehmbares Rohr ö, das zwischen die Werkzeugteile 1b und 2b geschoben wird. Wenn das vVerkzeugteil 2b nach oben bewegt wird, werden die Ränder 6 und 9 beider Bleche zwischen diesem Werkzeugteil und dem Werkzeugteil 1b festgeklemmt. Damit dies möglich ist, ist das Werkzeugteil 2b mit einer Aussparung 10 (Fig. 2a) für das Rohr 8 versehen, die groß genug ist, um auch für das BIech-If metal sheets are to be anchored on two opposite sides of an object, this can be done in a similar way as has just been described with reference to FIGS. 1a-1b, but the following modifications have to be made: Jiin second sheet 7 of the same type as sheet 5, in the case of eggs the j ^ olypropylene layer is turned towards the mold cavity, is applied to the lower half of the tool, as shown in Fig. 2a emerges. The injection channel is arranged between the metal sheets 5 and 7, for example via a removable tube ö, which is pushed between the tool parts 1b and 2b. When the tool part 2b is moved upwards, the edges 6 and 9 of both sheets clamped between this tool part and the tool part 1b. For this to be possible, this is Tool part 2b is provided with a recess 10 (Fig. 2a) for the tube 8, which is large enough to also accommodate the BIech-
