Abstract
Vorrichtung zur Herstellung von Spritzgußteilen, umfassend einen Formträger (23) sowie eine oder mehrere Formhälften (24a, 25a) von Spritzgußformen (24, 25), die auf dem Formträger (23) angebracht sind oder auf diesem anbringbar sind, wobei für den Formträger (23) einerseits und für die Formhälften (24a, 25a) andererseits eine getrennte Temperierung (64, 99a, 99b) vorgesehen ist.Apparatus for producing injection-molded parts, comprising a mold carrier (23) and one or more mold halves (24a, 25a) of injection molds (24, 25) mounted on or attachable to the mold carrier (23), the mold carrier ( 23) on the one hand and for the mold halves (24a, 25a) on the other hand a separate temperature (64, 99a, 99b) is provided.

Problematisch ist bei den Spritzgießmaschinen der vorgenannten Art, dass die auf den Formaufspannplatten befestigten Formhälften einerseits und die auf dem mittleren Formträger bzw. der Wendeplatte befestigten Formhälften andererseits im Betrieb temperiert werden müssen. Auch wenn alle Formhälften auf der gleichen Temperatur gehalten werden, kann es trotzdem dazu kommen, dass die Formhälften auf der Wendeplatte sich nicht mehr exakt mit den Formhälften auf den Formaufspannplatten zusammenfahren lassen und zwar deshalb, weil sich die temperaturbedingten Größenveränderungen der Formhälften auf den Formaufspannplatten nahezu gar nicht, auf der Wendeplatte aber signifikant bemerkbar machen.Problematic is in the injection molding machines of the aforementioned type, that the mold halves fastened on the platens on the one hand and on the middle mold carrier or the Turning plate attached mold halves on the other hand in operation need to be tempered. Even if all mold halves can be kept at the same temperature, it can anyway come that the mold halves on the insert are not more exactly with the mold halves on the platens let go because of the temperature-related Size changes of the mold halves almost not at all on the platens, on the insert but make a significant difference.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Spritzgießmaschine der vorgenannten Art dahingehend weiterzuentwickeln, dass die Formhälften auf der Wendeplatte stets exakt mit den Formhälften auf den Formaufspannplatten zusammengefahren werden können, und zwar unabhängig von der Temperierung der Formhälften.outgoing This is the object of the invention, an injection molding machine of the aforementioned type to the effect that the mold halves on the insert always exactly with the mold halves the mold clamping plates can be moved together, regardless of the temperature of the mold halves.
Die Lösung dieser Aufgabe erfolgt durch eine Vorrichtung mit den Merkmalen von Anspruch 1 und eine Spritzgießmaschine mit den Merkmalen von Anspruch 10. Vorteilhafte Ausgestaltungen und Weiterentwicklungen finden sich in den Unteransprüchen.The Solution to this problem is done by a device with the features of claim 1 and an injection molding machine with the features of claim 10. Advantageous embodiments and further developments can be found in the dependent claims.
Dadurch, dass für den Formträger, insbesondere in Gestalt einer Wendeplatte oder eines Würfels, und die auf dem Formträger befestigten Formhälften eine getrennte Temperierung vorgesehen ist, kann eine Größenveränderung des Formträgers unabhängig von der Temperierung der Formhälften vermieden oder nur in dem Maße zugelassen werden, wie auch auf den Formaufspannplatten eine Größenveränderung erfolgt. Jedenfalls können die Formhälften auf dem Formträger stets exakt zu den korrespondierenden Formhälften auf den Formaufspannplatte ausgerichtet gehalten werden. In diesem Zusammenhang gilt es auch zu beachten, dass es nach der Montage der Formhälften einige Zeit dauert, bis das gesamte System aus Formaufspannplatten, mittlerem Formträger und Formhälften auf der erforderlichen Betriebstemperatur ist. Aufgrund der unterschiedlichen Wärmeausdehnung der Formaufspannplatten einerseits und des mittleren Formträgers andererseits könnte es daher dazu kommen, dass die gesamte Spritzgießmaschine unmittelbar nach dem Einbau zwar exakt ausgerichtet ist, dass aber bei Erreichen der Betriebstemperatur der Formhälften die Ausrichtung der Formhälften nicht mehr stimmt. Durch die getrennten Temperierkreisläufe in dem mittleren Formträger einerseits und in den auf diesem befestigten Formhälften andererseits können die Temperaturen getrennt voneinander eingestellt werden. Insbesondere kann in den Formhälften eine für den jeweils verarbeiteten Kunststoff optimale Temperatur eingestellt werden und in Abhängigkeit davon kann der Formträger in der gewünschten Weise temperiert werden. Beispielsweise können die Formhälften auf einem Temperaturniveau von etwa 100°C bis 110°C gehalten werden, wohingegen der mittlere Formträger selbst auf ein Temperaturniveau von etwa 70°C bis 80°C eingestellt wird.Characterized in that a separate temperature is provided for the mold carrier, in particular in the form of a turning plate or a cube, and the mold halves mounted on the mold halves, a change in size of the mold carrier can be independent of the temperature of the mold halves ver avoid or allowed only to the extent that on the platens a size change takes place. In any case, the mold halves on the mold carrier can always be kept exactly aligned with the corresponding mold halves on the platen. In this context, it should also be noted that it takes some time after assembly of the mold halves, until the entire system of mold platens, middle mold carrier and mold halves is at the required operating temperature. Due to the different thermal expansion of the platens on the one hand and the central mold carrier on the other hand, it could happen that the entire injection molding machine is exactly aligned immediately after installation, but that when the operating temperature of the mold halves, the alignment of the mold halves is no longer true. Due to the separate temperature control circuits in the middle mold carrier on the one hand and in the mold halves mounted on the other hand, the temperatures can be set separately from each other. In particular, an optimum temperature for each processed plastic can be set in the mold halves, and depending on this, the mold carrier can be tempered in the desired manner. For example, the mold halves can be maintained at a temperature level of about 100 ° C to 110 ° C, whereas the middle mold carrier itself is set to a temperature level of about 70 ° C to 80 ° C.

Anstelle der hier beschriebenen Ausführungsform einer Spritzgießmaschine mit einer feststehenden und einer beweglichen Formaufspannplatte können auch zwei äußere bewegliche Formaufspannplatten vorgesehen werden, die auf einen ortsfesten mittleren Formträger zu und von diesem weg verfahren werden können.Instead of the embodiment of an injection molding machine described here with a fixed and a movable platen can also have two outer moving platens be provided on a stationary central mold carrier can be moved to and from this path.
Der mittlere Formträger kann drehbar, also insbsondere als Wendeplatte oder als drehbarer Würfel ausgebildet sein, wie dies bei den sogenannten Wendeplatten-Spritzgießmaschinen der Fall ist. Der mittlere Formträger kann aber auch nicht drehbar sein, wie dies bei einer Etagenspritzgießmaschine der Fall ist.Of the middle mold carrier can be rotated, so insbesondere as Turning plate or be designed as a rotatable cube, as with the so-called indexable insert molding machines the case is. But the middle mold carrier can not be rotatable, as in a floor injection molding machine Case is.
