Description

Preßwerkzeug zur Herstellung von Werkstücken aus Kunstharz o. dgl. Blei Preßwerkzeugen zur Herstellung von Massenteilen aus Kunstharzpreßstoffen u. dgl. sind Auswerfereimrichtungen bekannt, die nach dem Preßhub das Werkstück von den--Preßstemp,eln :abschieben. Die Einrichtungen zur Bewegung dieser Auswerfer warn -an einer Auswerferplatte angeordnet, .die durch eine außerhalb der Preßwerkzeuge . angeordnete. Gestängeeinrichtung inTätigkeit:ges:etzt wurde. Die Einstellung dieser Einrichtungen ist umständlich, außerdem wird durch die Gestänge der Zugang zu den Pneßwerkzeugen erschwert.Pressing tools for the production of workpieces from synthetic resin or the like. Lead pressing tools for the production of bulk parts from synthetic resin molded materials and the like are known ejector devices which push the workpiece off the press ram after the pressing stroke. The means for moving said ejector warning arranged -an an ejector, .the by an outside of the pressing tools. arranged. Linkage device in activity: set: was set. The setting of these facilities is cumbersome, and access to the pneumatic tools is made more difficult by the linkage.

Diesem Mangel hilft die Erfqndung - ab. Gemäß der _ Erfindung ist die in bekannter Weisse ,ausgebildete Auswerferplatte mit einemzentral zwischen den Stempeln angeordneten verschiebbaren Bolzen ausgerüstet, der im Preßunterteil in der Achsrichtung zu gleiten vermag und dessen- Hub durch Stellmuttern begrenzt ist.The invention remedies this deficiency. According to the invention is the known white, trained ejector plate with a central between the punches arranged displaceable bolt equipped in the lower part of the press able to slide in the axial direction and its stroke is limited by adjusting nuts is.

Die Erßndumg ist durch die Zeichnung beispielsweise veranschaulicht, und zwar durch zwei parallel zur Preßwerkzeugachse geführte senkrechte Schnitte bei zwei verschiedenen Arbeitsstellungen.The basic concept is illustrated by the drawing, for example, namely through two vertical cuts made parallel to the press tool axis in two different working positions.

Abb. i zeigt den Augenblick dies Pressens, Abb. z den Augenblick, in dem die Auswerfer in Tätigkeit treten und die Werkstücke aus Kunstharz io. dgl. von den Preßstemp:eln abgeschohen haben.Fig.i shows the moment of pressing, Fig.z the moment in which the ejectors come into action and the workpieces made of synthetic resin io. like have peeled off the press ram.

Das Preßwerkzeug besteht in üblicher Weise aus --mein: Preßunterteil a mit matrizenartigen Aussparungen und seiner eine Mehrzahl von Preßstempeln b tragenden Platte c, die unter Vermittlung von Abstandsrollen d an einer Aufspannplatte e befestigt ist. In der Achsrichtung der Stempel b sind Auswerfer f verschiebbar, die an einier Platte g befestigt sind, welche zwischen der Aufspannplatte e und .der Stempelhalterplatte c bewegbar ist. Wenn die Stempiel b zum Formen der Werkstücke h in den Preßunterteila eingedrungen sind, werden, wie Abb. i zeigt, die Auswerferbolzen so weit zurückgedrückt, bis die Platte g sich an die Aufspannplattee anlegt-. Wenn nach Vollendung der Pressung die Plattee von dem Preßunterteil a zurückweicht, so suchen die Werkstücke h, die an den -S'temp-eln b festsitzen, die Teile t, g mit lemp@orzunehmen. An der Platte g ist nun zentral zwischen den Stempeln b ein Bolzen! befestigt, der in einer Öffnung k im Preßunterteil a zu gleiten -vermag. Nach einem gewissen Hubwege treffen Stellmuttern m, m' am unteren Ende dies Bolzens i auf die Unterseite der Plattenöffnung-k, begrenzen. damit den Aufwäxtsgang der Platte g. Von diesem Augenblick an bewegen sich die Auswerferbolzen f relativ zu den Stempeln b und stoßen die Werkstücke ab.The pressing tool consists in the usual way of - my: lower pressing part a with die-like recesses and its plate c carrying a plurality of pressing punches b, which is fastened to a mounting plate e with the help of spacer rollers d. Ejectors f, which are attached to a plate g, which can be moved between the clamping plate e and the punch holder plate c, can be displaced in the axial direction of the punches b. When the stem game b have penetrated into the Preßunterteila to form the workpieces h, the ejector pins are pushed back as far as shown in Fig. I until the plate g rests against the clamping plate. If, after completion of the pressing, the plate moves back from the lower press part a, the workpieces h that are stuck on the -S'temp-eln b try to pick up the parts t, g with lemp @. On the plate g there is now a bolt centrally between the punches b! attached, able to slide in an opening k in the lower press part a. After a certain stroke, adjusting nuts m, m ' meet at the lower end of this bolt i on the underside of the plate opening-k, delimit. so that the Aufwäxtsgang the plate g. From this moment on, the ejector pins f move relative to the punches b and repel the workpieces.

Infolge der zentralen Anordnung des Bolzens i bleibt die Anordnung übersichtlich. Man 'kann,, von allen Seiten zu den einzelnen Matrizen bzw. Stempeln gelangen. Weiter ist es auf die einfachste Weise möglich, durch Verstellen der Muttern m, m' den Auswerferhub x der Bolzen f zu regeln.As a result of the central arrangement of the bolt i, the arrangement remains clear. You can get to the individual dies or punches from all sides. It is also possible in the simplest way to regulate the ejector stroke x of the bolts f by adjusting the nuts m, m '.
