Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen einer angelenkten Klappe beim Spritzgießen, Pressen od. dgl. eines Formteils nach dem Oberbegriff des Anspruchs 1 und ein Formteil mit einer angelenkten Klappe nach dem Oberbegriff des Anspruchs 4.The invention relates to a method for producing a hinged flap during injection molding, pressing od. Like. A molded part according to the preamble of claim 1 and a molded part with a hinged flap according to the preamble of Claim 4.
Derartige Formteile finden u.a. in
der Automobilindustrie beispielsweise für die unterseitige Abdeckung
des Motorraums Verwendung, wobei eine Klappe zwecks Ölwechsels
vorgesehen ist. So ist aus
Ein Verfahren zum Herstellen eines
Formteils mit einer Klappe ohne Verwendung einer Einlage für das Scharnier
ist z.B. aus der
Der Erfindung liegt daher die Aufgabe zugrunde, das vereinfachte und kostengünstigere Herstellen einer angelenkten Klappe beim Spritzgießen, Pressen od. dgl. eines Formteils zu ermöglichen.The invention is therefore the object underlying, the simplified and cheaper manufacture of a hinged Flap in injection molding, pressing od. Like. To allow a molded part.
Diese Aufgabe wird entsprechend den Merkmalen des Anspruchs 1 bzw. 4 gelöst.This task is carried out according to the Features of claims 1 and 4 solved.
Hierzu wird ein Verfahren zum Herstellen einer angelenkten Klappe beim Spritzgießen, Hinterspritzen bzw. Hinterlegen eines Dekormaterials, Pressen od. dgl. eines Formteils aus vorzugsweise faserverstärktem Kunststoff mit einer mehrteiligen Spritz- bzw. Preßform geschaffen, bei dem ein Scharnier für die Klappe durch Formen eines eingekerbten Bereichs zwischen dem Formteil und der Klappe ausgebildet, in den Bereich des Scharniers gegenüber von dem Rücken des den eingekerbten Bereich erzeugenden Formteils ein zurückziehbarer Stempel um eine vorbestimmte Höhe eingeführt, das Formteil aus dem vorzugsweise faserverstärkten Kunststoff gespritzt bzw. gepreßt, der Stempel vorzugsweise bis zur Ebene des Formteils im Bereich des Scharniers herausgezogen und in den entstehenden Hohlraum ein Streifen aus einem flexiblen thermoplastischen Kunststoff eingespritzt wird.This is done using a manufacturing process a hinged flap during injection molding, injection molding or depositing a decorative material, presses or the like. A molded part made of preferably fiber-reinforced plastic created with a multi-part injection or compression mold, in which a Hinge for the flap by forming a notched area between the Molding and the flap formed in the area of the hinge across from the back a retractable of the molded part producing the notched area Stamp by a predetermined amount introduced, the molded part is injected from the preferably fiber-reinforced plastic or pressed, the stamp preferably up to the level of the molded part in the area pulled out of the hinge and into the resulting cavity Injected strips of a flexible thermoplastic becomes.
Da die Form nicht geöffnet werden muß, um den Streifen anzubringen, und auch ein nachträgliches Prägen und Behandeln des Formstücks entfallen, ergibt sich eine erheblich Vereinfachung und Kostenreduzierung gegenüber den bekannten Verfahren.Because the mold cannot be opened must to To apply strips, and there is also no need to subsequently stamp and treat the shaped piece, there is a considerable simplification and cost reduction compared to the known methods.
Der eingekerbte Bereich trennt das Formteil in einen Hauptkörper und eine Klappe, die durch den Streifen gelenkig miteinander verbunden sind. Hierbei ist der Schwenkbereich der Klappe durch die Form der Einkerbung und den Abstand zwischen Hauptkörper und Klappe festlegbar. Grenzen der Hauptkörper und die Klappe beispielsweise bei einer V-förmigen Einkerbung aneinander, hängt der Schwenkbereich in Richtung der Einkerbung von deren Öffnungswinkel ab. Sind hingegen der Hauptkörper und die Klappe beispielsweise bei einer U-förmigen Einkerbung weit voneinander beabstandet, ist die Klappe vollständig in beide Richtungen umklappbar.The notched area separates that Molding in a main body and a flap hinged together by the strip are. Here, the swivel range of the flap is due to the shape of the Notch and the distance between the main body and flap can be determined. Limits of the main body and the flap, for example in the case of a V-shaped notch, depends on the swivel range in the direction of the notch from its opening angle. However, are the main body and the flap is far apart, for example in the case of a U-shaped notch spaced apart, the flap can be folded completely in both directions.
Der Stempel kann eine eingekerbte Stempelfläche für eine Einkerbung im Streifen aufweisen. Hierdurch kann die bevorzugte Umklapprichtung der Klappe festgelegt werden.The stamp can be a notched stamp surface for one Have a notch in the strip. This can be the preferred Folding direction of the flap can be determined.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention are to the following description and the dependent claims remove.
Die Erfindung wird nachstehend anhand von in den beigefügten Abbildungen dargestellten Ausführungsbeispielen näher erläutert.The invention is illustrated below from in the attached Illustrations shown embodiments explained in more detail.
