Abstract

A plastic moulding is produced with an outer skin by placing the skin between top and bottom mould tools and pressing the moulding material against the skin by means of an integral punch tool, so that at least one rim part of the moulding is basically aligned in the demoulding direction. In this rim area the skin is gripped in an L-section by means of a sliding tool held between the top and bottom mould tools. The outer skin is pressed by the moulding material and the lower punch tool once the skin is in position between the upper and lower tools. When the upper tool has been moved down as far as possible the punch presses upwards. The top of the punch lies against the mould shot. The outer rim of the mould is in the direction of movement of the mould opening and the rim is completely covered by the skin. The sliding member engages the skin to fold it inwards. ADVANTAGE - Produces mouldings which are free from leaked quantities of material round the edge

Description

Die Erfindung betrifft ein Herstellverfahren für ein eine Außenhaut aufweisendes Kunststoff-Formteil, wobei die Außenhaut zwischen die Oberform und Unterform eines Werk­ zeuges eingelegt und die Kunststoffmasse mittels eines Stempels, der Bestandteil der Werkzeug-Unterform ist, auf die Außenhaut aufgepreßt wird, und wobei zumindest ein Randabschnitt des Formteiles im wesentlichen in Werkzeug- Entformrichtung ausgerichtet ist.The invention relates to a manufacturing method for a Plastic molded part with outer skin, the Outer skin between the upper form and lower form of a work inserted and the plastic mass by means of a Stamp, which is part of the mold base, on the outer skin is pressed on, and at least one Edge section of the molded part essentially in tool De-molding direction is aligned.

Ferner betrifft die Erfindung ein Werkzeug, insbesondere zur Durchführung des erfindungsgemäßen Herstellverfah­ rens, zum Hinterpressen einer Außenhaut mit einer Kunst­ stoffmasse, bestehend aus einer Werkzeug-Oberform sowie einer Werkzeug-Unterform mit einem Stempel zum Aufpressen der Kunststoffmasse.The invention further relates to a tool, in particular to carry out the manufacturing process according to the invention rens, for pressing an outer skin with an art mass of material, consisting of an upper mold and a tool bottom mold with a stamp for pressing the plastic mass.

Der Stand der Technik ist in der deutschen Patentschrift 8 33 118 beschrieben. Dabei soll ausdrücklich darauf hin­ gewiesen werden, daß die Begriffe "Werkzeug-Oberform" so­ wie "Unterform" nicht exakt geodätisch gedeutet werden dürfen, vielmehr kennzeichnen diese Begriffe die beiden Formhälften eines Werkzeuges, die selbstverständlich auch nebeneinander oder überkopfstehend angeordnet sein kön­ nen.The state of the art is in the German patent specification 8 33 118. It should expressly point this out be pointed out that the terms "mold top shape" so how "subform" cannot be interpreted exactly geodetically these terms characterize the two Mold halves of a tool, of course, too  can be arranged side by side or overhead nen.

Bei den bekannten Herstellverfahren ist es möglich, daß geringe Mengen der Kunststoffmasse über den Rand des Formteiles hinaustreten, so daß auch nach Umschlagen der sich zumeist über den Rand hinaus fortsetzenden Außenhaut kein sauberer und exakter Formteil-Randabschnitt ent­ steht. Ein Herstellverfahren sowie ein hierfür geeignetes Werkzeug aufzuzeigen, mit dem die oben beschriebene Problematik nicht mehr auftritt, ist Aufgabe der Erfin­ dung.In the known manufacturing processes, it is possible that small amounts of the plastic mass over the edge of the Step out of the molded part, so that even after turning the the outer skin usually continues beyond the edge no clean and exact molding edge section ent stands. A manufacturing process and a suitable one Show tool with which the one described above Problems no longer occur, is the task of the inventor dung.

Gelöst wird diese Aufgabe, indem beim Herstellverfahren die Außenhaut im Randabschnitt mittels eines zwischen der Werkzeug-Oberform und der Werkzeug-Unterform eingespann­ ten Schiebers die einzubringende Kunststoffmasse im we­ sentlichen L-förmig umfassend gehalten wird.This task is solved by the manufacturing process the outer skin in the edge section by means of a between the Tool upper mold and the tool lower mold clamped ten slider the plastic mass to be introduced in the white substantial L-shaped is held extensively.

Ein entsprechendes Werkzeug ist gekennzeichnet durch einen bei geschlossenem Werkzeug zwischen der Oberform und der Unterform eingespannten und die Außenhaut gegen die Unterform pressenden Schieber.A corresponding tool is identified by one with the tool closed between the top mold and clamped the lower mold and against the outer skin the lower mold pressing slide.

Anspruch 2 beschreibt eine vorteilhafte Weiterbildung des Herstellverfahrens. Weitere Vorteile sowie Merkmale wer­ den aus der folgenden Beschreibung eines bevorzugten Aus­ führungsbeispiels, das der näheren Erläuterung der Erfin­ dung dient, ersichtlich. Die Prinzipskizze zeigt einen Schnitt durch ein geschlossenes Werkzeug.Claim 2 describes an advantageous development of Manufacturing process. Other advantages and characteristics of who from the following description of a preferred Aus management example, the more detailed explanation of the Erfin serving serves. The schematic shows one Cut through a closed tool.

Hergestellt werden soll ein Kunststoff-Formteil 1, das eine Außenhaut 1a besitzt, auf die eine Kunststoffmasse 1b aufgepreßt wird. Hierzu wird die Außenhaut 1a in ein Werkzeug 2 eingelegt, das u. a. aus einer Oberform 2a so­ wie einer Unterform 2b besteht. Nachdem das Werkzeug ge­ schlossen wurde, d. h. nachdem die Oberform 2a gemäß Pfeilrichtung 3 (Werkzeug-Entformrichtung 3) so nahe als möglich gegen die Unterform 2b gefahren wurde, wird die Kunststoffmasse 1b mittels eines Stempels 2c aufgepreßt. Dieser Stempel 2c ist Bestandteil der Unterform 2b und ist allseits von deren seitlichen Randbereichen beabstan­ det. Dabei steht der Stempel 2c zunächst in der in strich-punktierten Linien dargestellten Position, während sich oberhalb des freien Endes 5 des Stempels 2c die auf­ zupressende Kunststoffmasse befindet. Nach Schließen des Werkzeuges 2 wird der Stempel 2c gemäß Pfeilrichtung 3 gegen die Oberform 2a bewegt, bis das freie Ende 5 in der durch die Oberfläche 6 der Werkzeug-Unterform 2b be­ schriebenen Ebene liegt. Hierdurch gelangt die Kunst­ stoffmasse 1b in den Freiraum zwischen der Oberform 2a und der Unterform 2b und wird dabei auf die Außenhaut 1a aufgepreßt.A molded plastic part 1 is to be produced , which has an outer skin 1 a, onto which a plastic mass 1 b is pressed. For this purpose, the outer skin 1 a is inserted into a tool 2 , which consists, among other things, of an upper mold 2 a and a lower mold 2 b. After the tool was closed ge, ie after the upper mold 2 a was moved as close as possible against the lower mold 2 b according to the direction of arrow 3 (mold removal direction 3 ), the plastic mass 1 b is pressed on by means of a stamp 2 c. This stamp 2 c is part of the lower mold 2 b and is beabstan det on all sides of the lateral edge regions. The stamp 2 c is initially in the position shown in dash-dotted lines, while above the free end 5 of the stamp 2 c is the plastic mass to be pressed. After closing the tool 2 , the stamp 2 c is moved in the direction of the arrow 3 against the upper mold 2 a until the free end 5 lies in the plane written by the surface 6 of the tool lower mold 2 b. As a result, the plastic mass 1 b gets into the space between the upper mold 2 a and the lower mold 2 b and is pressed onto the outer skin 1 a.

Der Randabschnitt 4 des Formteiles ist im wesentlichen in Werkzeug-Entformrichtung 3 ausgerichtet. Um den Rand des Randabschnittes 4 des Formteiles 1 sauber zu gestalten, umgreift die Außenhaut 1a die Kunststoffmasse 1b im we­ sentlichen L-förmig. Im Sichtbereich ist die Kunststoff­ masse 1b des Kunststoff-Formteiles 1 somit vollständig von der Außenhaut 1a bedeckt.The edge section 4 of the molded part is essentially aligned in the mold removal direction 3 . In order to make the edge of the edge section 4 of the molded part 1 clean, the outer skin 1 a engages the plastic mass 1 b in an essentially L-shaped manner. In the field of vision, the plastic mass 1 b of the plastic molded part 1 is thus completely covered by the outer skin 1 a.

Realisiert werden kann der beschriebene und gezeigte Ver­ lauf der Außenhaut 1a mittels eines Schiebers 7, der die sich noch über den Bereich der Kunststoffmasse 1b hinaus­ streckende Außenhaut 1a so hält, daß die Außenhaut 1a die Kunststoffmasse 1b im Randabschnitt 4 im wesentlichen L-förmig umfaßt. Dieser Schieber 7 ist bei geschlossenem Werkzeug 2 zwischen der Oberform 2a und der Unterform 2b eingespannt und hält auf diese Weise sicher die zwischen der Unterform 2b sowie dem Schieber 7 eingespannte Außen­ haut 1a. The Ver described and shown can be realized course of the outer skin 1 a by means of a slide 7, which is still over the range of the plastic mass 1 b also stretching the outer skin 1 a so holds that the outer skin 1 a, the plastic compound 1b in the edge portion 4 in the essentially L-shaped. This slider 7 is in the closed tool 2 between the upper mold and the lower mold 2 a 2 b clamped and does by this means secure the between the bottom mold 2 b, and the slider 7 is clamped outer skin 1 a.

Wie ersichtlich liegt mit Abschluß des Aufpressens der Kunststoffmasse 1b das freie Ende 5 des Stempels 2c in der durch die Oberfläche 6 der Werkzeug-Unterform 2b be­ schriebenen Ebene. Dies gestattet es, das Kunststoff- Formteil 1 im wesentlichen nacharbeitsfrei aus dem Werk­ zeug 2 zu entnehmen. Dieses sowie weitere Details können jedoch durchaus anderweitig gestaltet sein, ohne den In­ halt der Patentansprüche zu verlassen.As can be seen is with completion of pressing of the plastic mass 1 b, the free end 5 of the slide 2 in the c by the surface 6 of the mold lower die 2 b be signed level. This allows the plastic molded part 1 to be removed from the work tool 2 essentially without rework. However, this and other details can also be designed otherwise, without leaving the content of the claims.
