Vorrichtung zur Herstellung von Radialwälzlagerkäfigen aus Kunststoff Device for the production of radial roller bearing cages made of plastic
Die Erfindung betrifft eine Vorrichtung zur Herstellung von Radialwälzlagerkäfigen aus Kunststoff, bei denen zwei Ringborde durch über den Umfang verteilte Stege miteinander verbunden sind, bestehend aus einem an sich bekannten Spritzwerkzeug mit einem dem Käfiginnendurchmesser entsprechenden zylindrischen Kern und einem Werkzeugaußenteil mit radial bewegbaren Schiebern.The invention relates to a device for producing radial roller bearing cages made of plastic, in which two ring ribs are connected to one another by webs distributed over the circumference, consisting of an injection mold known per se with a cylindrical core corresponding to the inner diameter of the cage and an outer tool part with radial movable slides.
Derartige Spritzwerkzeuge werden seit langem zur Herstellung von sogenannten Fensterkäfigen verwendet. Nachteilig wirken sich dabei die relativ hohen Gestehungskosten aus, die einerseits durch die reinen Werkzeugkosten bedingt sind und andererseits aus der Tatsache resultieren, daß in einem Spritzzyklus jeweils nur ein Käfig gefertigt werden kann.Such injection tools have long been used for the production of so-called window cages. Act disadvantageous The relatively high production costs, which on the one hand are due to the pure tool costs and on the other hand, are evident result from the fact that only one cage can be manufactured in one injection cycle.
Dies wiederum hat zur Folge, daß sich insbesondere bei der Fertigung großer Serien eine übermäßig lange Belegung der Spritzmaschine mit einem Werkzeug und dadurch eine unwirtschaftliche Ausnutzung der Spritzmaschine ergibt.This in turn has the consequence that, especially in the production of large series, an excessively long occupancy of the Injection machine with one tool and therefore an uneconomical one Utilization of the injection molding machine results.
Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Nachteile in einfacher und fortschrittlicher Weise zu beheben und einen Weg aufzuzeigen, die Fertigungskosten erheblich zu senken und die Kapazität der Spritzmaschine wirtschaftlicher zu nutzen.The invention is based on the object of eliminating the disadvantages outlined in a simple and progressive manner and to show a way to reduce manufacturing costs considerably and make the capacity of the injection molding machine more economical to use.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Spritzwerkzeug Ausnehmungen zur gleichzeitigen Herstellung von zwei Käfigen aufweist, die gleichachsig hintereinander und im Abstand voneinander angeordnet sind, wobei die Begrenzungen für die einander zugekehrten Stirnflächen der Ringborde von den Schiebern gebildet sind. Eine solche Ausbildung gestattet es, mit einem geringen Mehraufwand an Herstellungskosten für das Spritzwerkzeug eine 1OO%ige Leistungssteigerung zu erzielen, die nicht nur eine wesentliche Kostensenkung für den einzelnen Käfig bringt sondern auch die Belegung der Spritzmaschine mit einem Spritzwerkzeug beträchtlich verkürzt.According to the invention, this object is achieved in that the injection molding tool has recesses for simultaneous production of two cages, which are coaxially arranged one behind the other and at a distance from one another, the boundaries for the mutually facing end faces of the ring rims are formed by the slides. Such training allows a 100% increase in performance with a small additional cost in terms of manufacturing costs for the injection molding tool to achieve, which brings not only a significant cost reduction for the individual cage but also the occupancy the injection molding machine considerably shortened with an injection molding tool.
In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß jede Ausnehmung einen Anspritzkanal aufweist, die beide in einen zwischen den Ausnehmungen liegenden und "mit dem zentralen Spritzkanal im Kern in Verbindung stehenden Kanal münden. Durch diese Maßnahme ergibt sich der Vorteil, daß die in die einzelnen Ausnehmungen mündenden Anspritzkanäle sehr kurz gehalten und dadurch an ihrem freien Ende einen so geringen Durchmesser aufweisen können, daß der Anguß beim Öffnen des Spritzwerkzeuges ohne Schwierigkeiten abgerissen wird und so ein störungsfreier Spritzzyklus sichergestellt ist.In a further embodiment of the invention it is proposed that each recess has an injection channel, both of which into a channel located between the recesses and connected to the central injection channel in the core flow out. This measure has the advantage that the injection channels opening into the individual recesses kept very short and can therefore have such a small diameter at their free end that the sprue when Opening the injection mold is torn off without difficulty, thus ensuring a trouble-free injection cycle is.
Nach einem anderen Merkmal der Erfindung ist vorgesehen, daß der Kern in einer quer zur Längsachse des Spritzwerkzeuges verlaufenden Ebene teilbar ist. Mit besonderem Vorteil ist die Ausbildung dabei so getroffen, daß die Teilungsebene zwischen den Ausnehmungen liegt. Eine solche Anordnung begünstigt einerseits einen reibungslosen Arbeitsablauf, da die vorgeschlagene Lage der Teilungsebene das Ausstoßen des Angusses in besonders einfacher Weise gestattet, andererseits wird die Herstellung des Spritzwerkzeuges dadurch vereinfacht, daß die einzuarbeitenden Spritzkanäle in der Teilungsebene liegen.According to another feature of the invention it is provided that the core in a transverse to the longitudinal axis of the injection molding tool running plane is divisible. With particular advantage, the training is made so that the plane of division between the recesses. Such an arrangement favors on the one hand a smooth workflow, since the proposed Position of the parting plane allows the sprue to be ejected in a particularly simple manner, on the other hand the production of the injection molding tool is simplified in that the injection channels to be incorporated are in the parting plane lie.
