Abstract

The injection moulding machine known from the main Patent 3428780 possesses a central, split mould-mounting plate. By releasing the quick-action clamping device, the two plate parts can be moved laterally with one mould half in each case and by this means the melt-feed system be made accessible from both sides. Using the present invention, an enlargement takes place such that the injection moulding in only one mould in each case or the simultaneous injection moulding in two moulds of different design is possible. For this purpose, the central, movable mould-mounting plate is designed so as to be split into three and the melt-feed system is arranged between the three parts. The central mould-mounting plate, split into three, may be clamped together by means of one or more quick-action clamping device(s) to form a unit. <IMAGE>

Description

Die Erfindung betrifft eine Spritzgießmaschine zum Herstellen von Kunststoffteilen aus Thermoplasten, Duroplasten und/oder Elastomeren im Spritzgießverfah­ ren oder Reaktionsspritzgießverfahren, mit einer Mehr­ stationen-Schließeinheit, entsprechend dem Oberbegriff des Patentanspruchs 1.The invention relates to an injection molding machine for Manufacture of plastic parts from thermoplastics, Thermosets and / or elastomers in the injection molding process ren or reaction injection molding process, with a more Station locking unit, according to the preamble of claim 1.

Eine derartige Spritzgießmaschine ist Gegenstand des Patent­ anspruchs 1 des Hauptpatents 34 28 780. Such an injection molding machine is the subject of the patent claim 1 of the main patent 34 28 780.  

Mit der aus dem Hauptpatent 34 28 780 bekannten Spritzgieß­ maschine können größere Teile, insbesondere Karosse­ rieteile aus Kunststoff im Spritzgießverfahren oder Reaktionsspritzgießverfahren äußerst wirtschaftlich hergestellt werden. Durch Lösen der Schnellspannvor­ richtung können die beiden Plattenteile der mittle­ ren geteilten Formaufspannplatte mit je einer Form­ hälfte seitlich verfahren werden, wodurch das Schmel­ zeleitsystem völlig freigelegt und damit beidseitig zugängig ist.With the injection molding known from the main patent 34 28 780 machine can handle larger parts, especially body plastic parts in injection molding or Reaction injection molding process extremely economical getting produced. By releasing the quick release the two plate parts of the middle can be oriented ren split platen with one shape each half can be moved sideways, causing the melt time system completely exposed and thus on both sides is accessible.

Über die mittlere geteilte Formaufspannplatte ist das gleichzeitige Abspritzen zweier identischer For­ men möglich.Is over the middle split platen the simultaneous spraying of two identical For possible.

Durch die vorliegende Erfindung soll eine Verbesserung der geteilten mittleren Formaufspannplatte dahinge­ hend vorgenommen werden, daß das Abspritzen nur je­ weils einer Form oder das gleichzeitige Abspritzen von zwei Formen unterschiedlicher Gestaltung möglich ist.The present invention is intended to provide an improvement the divided central platen hend be made that the hosing only ever because of a shape or simultaneous hosing of two shapes of different designs possible is.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die mittlere bewegbare Formaufspannplatte drei­ geteilt ausgebildet und zwischen den drei Teilen das Schmelzeleitsystem angeordnet ist.According to the invention, this object is achieved by that the middle movable platen three divided trained and between the three parts that Melt control system is arranged.

In Ausgestaltung der Erfindung kann jedem Teil des Schmelzeleitsystems eine gesonderte Spritzeinheit zugeordnet sein. Vor­ teilhafterweise ist die dreigeteilte Formaufspann­ platte durch mehrere Schnellspannvorrich­ tungen zu einer Einheit zusammengespannt. Es be­ steht die Möglichkeit, das Schmelzeleitsystem in Form von Schmelzeleitschienen auszubilden.In development The invention can be any part of the melt control system a separate injection unit can be assigned. Before the three-part mold clamping is geous plate through several quick release devices tied together to form a unit. It be  there is the possibility of the melt control system in shape of melt guide rails.

Durch die erfindungsgemäße Dreiteilung der mittleren bewegbaren Formaufspannplatte ist die Möglichkeit gegeben, jedes Schmelzeleitsystem an eine Spritzein­ heit anzuschließen und die jeweils zugeordnete Form gesondert auszuspritzen. Außerdem besteht die Mög­ lichkeit, über die mittlere Formaufspannplatte gleich­ zeitig zwei unterschiedliche Formen auszuspritzen.By dividing the middle into three according to the invention Movable platen is the possibility given each melt control system to a syringe unit and the assigned form to be sprayed out separately. There is also the possibility the same over the middle platen to inject two different forms at the same time.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher erläutert. Die einzige Figur zeigt einen Vertikal­ schnitt durch eine mittlere bewegbare Formaufspann­ platte.An embodiment of the invention is in the Drawing shown and is closer below explained. The only figure shows a vertical cut through a medium movable mold plate.

Wie die Figur zeigt, besteht die mittlere bewegbare Formaufspannplatte 4′ aus drei Teilen, zwischen denen das Schmelzeleitsystem 30 angeordnet ist. Die Form­ aufspannplatte 4′ ist über eine oder mehrere nicht dargestellte Schnellspannvorrichtung(en) zu einer Einheit zusammengespannt. Mit 32 sind die Düsen und mit 11 ist das Lager für die bewegbare mittlere Form­ aufspannplatte bezeichnet.As the figure shows, the middle movable platen 4 ' consists of three parts, between which the melt guide system 30 is arranged. The shape clamping plate 4 ' is clamped together to form a unit via one or more quick clamping device (s), not shown. With 32 the nozzles and with 11 the bearing for the movable middle shape platen is designated.
