Zwei-oder mehrteilige Netallform zur Herstellung von Titrschnallen, Türknöpfen u. dgl. aus Kunstharz mit Metallkern.
Die Erfindung bezieht sich auf eine zwei-oder mehrteilige Metallform zur Herstellung von Türschnallen, Türknöpfen u. dgl. aus Kunstharz mit Metallkern. Bei Formen dieser Art macht es Schwierigkeiten, den Metallkern innerhalb der Form so einzustellen, dass die in die Form eingegossene Kunstharzmasse ihn gleichmässig umgibt. Dies ist insbesondere bei gebogenen Stücken, wie Türklinken, der Fall.
Die Erfindung bezweckt nun, diesem Cbelstand abzuhelfen.
In der Zeichnung ist eine beispielsweise Ausführungsform der Metallform dargestellt. Es zeigen Fig. 1 die eine Formhälfte mit einer in ihr liegenden Türklinke, Fig. 2 die Form in teilweisem Schnitt, Fig. 3 die Oberansicht der Form mit der Klemmvorrichtung für den Metallkern.
Die Form besteht aus zwei Teilen a, a'. An dem Teil a ist durch Schrauben c eine Platte b befestigt, die einen Führungsbügel d für den Metallkern trägt. In dem Bügel d ist eine Feststellschraube e und dieser gegenüber ein Keil f angeordnet. Durch die Schraube und den Keil kann das aus der Form herausragende,
EMI1.1
kern gleichmässig umgibt. Hierauf wird der Formteil a'auf den Formteil a aufgelegt und mit diesem in irgendeiner Art verbunden. Bei der Eingussstelle h wird nun das flüssige Kunstharz eingegossen, bis es die Hohlform vollständig ausgefüllt hat. Ist dies geschehen, so wird die Form in ein Dampfbad gebracht.
Infolge der guten Leitungsfähigkeit der Form und des Metal1kernes tritt ein verhältnismässig schnelles Erhärten des Harzes ein, das an der Aussenseite die Gestalt der Formhöhlung annimmt. Der so hergestellte Gegenstand bedarf nahezu keiner Nachbearbeitung.

Two-part or multi-part metal mold for the production of titration buckles, door knobs and the like. Like. Made of synthetic resin with a metal core.
The invention relates to a two-part or multi-part metal mold for the production of door buckles, door knobs and the like. Like. Made of synthetic resin with a metal core. With molds of this type, it is difficult to adjust the metal core within the mold so that the synthetic resin compound poured into the mold evenly surrounds it. This is especially the case with curved pieces such as doorknobs.
The invention now aims to remedy this situation.
In the drawing, an example embodiment of the metal mold is shown. 1 shows one mold half with a door handle lying in it, FIG. 2 shows the mold in partial section, FIG. 3 shows the top view of the mold with the clamping device for the metal core.
The shape consists of two parts a, a '. A plate b, which carries a guide bracket d for the metal core, is attached to part a by screws c. A locking screw e is arranged in the bracket d and a wedge f is arranged opposite it. Through the screw and the wedge, the protruding from the shape,
EMI1.1
evenly surrounds the core. The molded part a 'is then placed on the molded part a and connected to it in some way. At the injection point h, the liquid synthetic resin is poured in until it has completely filled the hollow mold. Once this is done, the mold is placed in a steam bath.
As a result of the good conductivity of the mold and the metal core, the resin hardens relatively quickly, and on the outside it takes the shape of the mold cavity. The object produced in this way requires almost no post-processing.
