Abstract
Description
Die Erfindung betrifft ein Werkzeug zur Herstellung elastischer Bauteile durch Spritzguß oder Ablegeverfahren sowie ein Verfahren zu deren Herstellung nach den Oberbegriffen der Patentansprüche 1 bzw. 5.The The invention relates to a tool for producing elastic components by injection molding or deposition process and a method for their preparation according to the preambles of the claims 1 or 5.
Zur Spritzgußherstellung elastischer Bauteile, die von einer Trägerplatte nach einer Seite abstehen und eine Öffnung oder Hinterschneidung haben, dienen in bekannter Weise Werkzeuge mit einer Schließeinheit, die aus einem Formunterteil und einem relativ dazu verschiebbaren Formoberteil bestehen, wobei dem Formoberteil ein Kern sowie ein Auswerferorgan zugeordnet sind. Die herkömmlichen Formoberteile benötigen für die Herstellung der Öffnung oder Hinterschneidung Werkzeugschieber, die allerdings gesonderte Führungen sowie einen eigenen Motor für ihren Antrieb erforderlich machen. Ferner sind Schrägauswerferorgane notwendig, die ebenfalls eine aufwändige Führung benötigen. Die bekannten Lösungen haben daher einen verhältnismäßig komplizierten Aufbau, erfordern einen großen Bauraum und sind bei der Herstellung sowohl zeitaufwändig als auch kostenintensiv.to injection molding production elastic components, from a carrier plate to one side stand out and an opening or undercut, are used in a known manner tools with a closing unit, that of a lower mold part and a relatively movable Formoberteil exist, wherein the upper mold part, a core and a Ejector are assigned. The conventional mold tops need for the production the opening or undercut tool slide, which, however, separate guides as well as its own engine for make their drive required. Furthermore, Schrägauswerferorgane necessary, which also require a complex tour. The known solutions have therefore a relatively complicated one Construction, require a large amount of space and are both time consuming and costly to manufacture.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Werkzeug zur Herstellung elastischer Bauteile mit einer Öffnung oder Hinterschneidung zur Verfügung zu stellen, das bei konstruktiv einfachem Aufbau in der Lage ist, die Bauteile platzsparend, kostengünstig und zeitsparend herzustellen.Of the Invention is therefore the object of a tool for manufacturing elastic components with an opening or undercut available to provide, which is in a structurally simple design able make the components space-saving, cost-effective and time-saving.
Diese Aufgabe wird durch ein Werkzeug mit den Merkmalen des Patentanspruchs 1 gelöst.These The object is achieved by a tool having the features of the patent claim 1 solved.
Zur Lösung der aufgezeigten Aufgabe ist ferner ein Verfahren zur Herstellung der genannten Bauteile mittels eines solchen Werkzeugs vorgesehen, das sich durch die Merkmale des Patentanspruchs 5 auszeichnet.to solution The object indicated is also a method for the production provided said components by means of such a tool, which is characterized by the features of claim 5.
Bei der Erfindung wird die Tatsache ausgenutzt, daß die Flexibilität der elastischen Bauteile für deren Zwangsentformung eingesetzt werden kann. Dabei wird in einer ersten Phase nach dem Erkalten oder Aushärten des verwendeten Werkstoffs das Auswerferorgan gemeinsam mit dem Kern relativ zu dem geöffneten Formoberteil verfahren, wodurch das Bauteil aus der Form ausgeschoben wird. In der unmittelbar anschließenden zweiten Phase wird der Kern an seinem Endanschlag angehalten, so daß nur noch das Auswerferorgan weiterverfahren wird; dabei wird die Elastizität der Bauteile, die von der Trägerplatte abstehen, genutzt, indem sich deren Schrägflächen für eine Zwangsentformung selbsttätig von den schrägen Begrenzungsflächen des Kerns lösen, ohne daß hierfür gesonderte Schieber oder Auswerfer benötigt werden.at The invention takes advantage of the fact that the flexibility of the elastic Components for their Forced removal can be used. It is in a first Phase after cooling or curing of the material used the ejector together with the core relative to the open Move mold top, whereby the component is ejected from the mold becomes. In the immediately following second phase becomes the core stopped at its end stop, so that only the ejector will continue; doing so is the elasticity of the components of the support plate stand, used by their inclined surfaces for compulsory removal automatically from the oblique boundary surfaces solve the core, without this separately Slider or ejector needed become.
Weitere Vorteile der Erfindung ergeben sich aus den Patentansprüchen und aus der folgenden Beschreibung von Ausführungsbeispielen, die in der Zeichnung dargestellt sind. Es zeigen:Further Advantages of the invention will become apparent from the claims and from the following description of exemplary embodiments, in the drawing are shown. Show it:
