Abstract
Description
Die Erfindung betrifft eine Spritzgießmaschine zum Her stellen von Kunststoffteilen aus Chemiewerkstoffen mit einer längsgeteilten Formaufspannplatte, an der ein oder beidseitig je eine Formhälfte einer Form befestigt ist und zwischen deren beiden Teilen das Schmelzeleit system angeordnet ist, wobei die beiden Teile durch eine Schnellspannvorrichtung zusammengehalten sind, nach deren Lösen ein Teil oder beide Teile seitlich auf Führungsholmen verfahrbar ist bzw. sind.The invention relates to an injection molding machine for manufacture provide plastic parts made of chemical materials a longitudinally shaped platen on which a or a mold half of a mold is attached on both sides is and between the two parts of the fusible conductor system is arranged, the two parts by a quick release device is held together, after loosening one part or both parts laterally is or can be moved on guide rails.
Bei den bekannten Spritzgießmaschinen (DE-PS 34 28 780) sind die Formhälften beidseitig auf der längsgeteilten Formaufspannplatte fest angeordnet. Die Schmelze wird bei dieser Ausbildung vom Schmelzeleitsystem durch einen Teil der geteilten Formaufspannplatte und durch eine Formhälfte der Form zum Formnest geführt.In the known injection molding machines (DE-PS 34 28 780) are the mold halves on both sides of the longitudinally divided Mold platen firmly arranged. The melt will in this training from the melt control system a part of the split platen and through one half of the mold led to the mold nest.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Spritzgießmaschine der aufgezeigten Gattung den Fließ weg vom Schmelzeleitsystem zum Formnest zu reduzieren. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein oder beide Teile der längsgeteilten Formaufspann platte einen Durchbruch aufweist bzw. aufweisen, der bzw. die zur Aufnahme einer Formhälfte als Kassettenaufnahme ausgebildet ist bzw. sind. In Ausgestaltung der Erfin dung ist der Durchbruch mittig angeordnet. Bei einer be vorzugten Ausführungsform weist der Durchbruch eine sol che Größe auf, daß das Teil der verbleibenden Formauf spannplatte einen Rahmen bildet. Es ist vorteilhaft, wenn die Stirnflächen des Durchbruchs mit Paßstücken versehen sind, die umlaufend oder im Abstand zueinander angeordnet sein können.The invention has for its object in a Injection molding machine of the type shown the flow to reduce away from the melt control system to the mold nest. This object is achieved in that one or both parts of the slit mold plate has or have a breakthrough which that for holding a mold half as a cassette holder is or are trained. In the form of the Erfin the breakthrough is arranged in the middle. With a be preferred embodiment, the breakthrough has a sol size on that part of the remaining shape clamping plate forms a frame. It is beneficial if the end faces of the opening with fittings are provided that are circumferential or at a distance from each other can be arranged.
Durch diese Ausbildung wird die Formhälfte um die Stärke eines Teils der geteilten Formaufspannplatte näher zum Schmelzeleitsystem herangeführt, wodurch eine Reduzierung des Fließwegs der Schmelze vom Schmelzeleitsystem zum Formnest erreicht wird.Through this training, the mold half becomes the strength part of the split platen closer to Melt control system introduced, thereby reducing the flow path of the melt from the melt control system to Form nest is reached.
Ein Ausführungsbeispiel der Erfindung ist in der Zeich nung dargestellt und wird im folgenden näher beschrie ben. Es zeigen:An embodiment of the invention is in the drawing shown and will be described in more detail below ben. Show it:
Fig. 1 einen Querschnitt durch eine geteilte Formauf spannplatte und Fig. 1 shows a cross section through a divided form on clamping plate and
Fig. 2 einen Längsschnitt durch eine geteilte Formauf spannplatte mit je einem Durchbruch auf den beiden Teilen. Fig. 2 shows a longitudinal section through a divided Formauf clamping plate, each with an opening on the two parts.
Jedes Teil der geteilten Formaufspannplatte 1 besitzt einen Durchbruch 2, der zur Aufnahme einer Formhälfte als Kassettenaufnahme ausgebildet ist. Die beiden Teile sind durch eine nicht dargestellte Schnellspannvorrich tung zusammengehalten. Die Formaufspannplatte 1 ist in Halbschalenlagern 5 auf jeweils vier Führungsholmen 6 gelagert und geführt. Nach Lösen der Schnellspannvor richtung ist ein seitliches Verfahren der Teile der Formaufspannplatte 1 möglich, so daß das zwischen den Teilen angeordnete Schmelzeleitsystem 7 zugängig ist. Auf den Stirnflächen 3 des Durchbruchs 2 sind Paßstücke 4 im Abstand zueinander angeordnet. Die Paßstücke 4 dienen zur exakten mittigen Positionierung der nicht dargestellten Formhälfte. Each part of the split platen 1 has an opening 2 , which is designed to receive a mold half as a cassette holder. The two parts are held together by a Schnellspannvorrich device, not shown. The platen 1 is supported and guided in half-shell bearings 5 on four guide rails 6 each. After loosening the Schnellspannvor direction, a lateral movement of the parts of the platen 1 is possible so that the melt control system 7 arranged between the parts is accessible. On the end faces 3 of the opening 2 adapters 4 are arranged at a distance from each other. The adapters 4 are used for the exact central positioning of the mold half, not shown.
