Abstract
Description
Die Erfindung betrifft eine Düse mit einer Aufnahme für Schmelzeaufbereitungselemente zum Anschluss an einen Plastifizierzylinder einer Standard-Kunststoffverarbeitungsmaschine, insbesondere einer Spritzgieß- oder Extrudiermaschine zur Verarbeitung thermoplastischer Kunststoffschmelzen.The invention relates to a nozzle with a receptacle for melt processing elements for connection to a plasticizing cylinder of a standard plastic processing machine, in particular an injection molding or extrusion machine for processing thermoplastic polymer melts.
Kunststoffverarbeitungsmaschinen insbesondere Spritzgieß- oder Extrudiermaschinen besitzen Düsen, durch welche die in einem beheizten Plastifizierzylinder aufgeschmolzenen Spritzgießmassen in Spritzgieß- oder Extrudierformen eingespritzt werden. Diese Düsen sind immer zwischen dem Plastifizierzylinder und der Spritzgieß- oder Extrudierform angeordnet.Plastic processing machines, in particular injection molding or extrusion machines, have nozzles through which the injection molding compounds melted in a heated plasticizing cylinder are injected in injection molds or extruding molds. These nozzles are always arranged between the plasticizing cylinder and the injection molding or extrusion mold.
Aus der
Die Firma Stamixco Technology AG vertreibt Mischdüsen für Spritzgießmaschinen mit einer Aufnahme für verschiedene Schmelzeaufbereitungselemente, die über eine Adapterverschraubung die Verwendung für Plastifizierzylinder mit unterschiedlichen Durchmessern ermöglicht. Dieser Adapter ist zwischen der Düse und dem Plastifizierinnenzylinder angeordnet, wodurch die Gesamtbaulänge der Düse erheblich verlängert wird. Ein Einsatz als „Austauschdüse” in Standard-Spritzgießmaschinen ist nur sehr eingeschränkt möglich, da der hierfür vorgesehene Einbauraum zwischen dem Plastifizierzylinder und der Spritzgieß- oder Extrudierform in aller Regel nur für die relativ kurzen Standarddüsen ausgelegt ist.The company Stamixco Technology AG distributes mixing nozzles for injection molding machines with a receptacle for various melt treatment elements, which allows the use of plasticizing cylinders with different diameters via an adapter fitting. This adapter is arranged between the nozzle and the plasticizing cylinder, whereby the overall length of the nozzle is considerably extended. A use as "replacement nozzle" in standard injection molding machines is only very limited, since the space provided for this purpose between the plasticizing cylinder and the injection molding or extrusion mold is usually designed only for the relatively short standard nozzles.
Alle bekannten Düsen mit Befestigungsgewinde, Standarddüsen und solche mit Aufnahme für Schmelzeaufbereitungselemente besitzen am Außenumfang Sechskantschlüsselflächen zum Werkzeugeingriff für Schraubenschlüssel für Sechskantschrauben nach DIN.All known nozzles with mounting thread, standard nozzles and those with receptacle for melt treatment elements have on the outer circumference hexagonal key surfaces for tool engagement for wrenches for hexagon screws according to DIN.
Nachteilig ist, dass sich die Düsen dadurch nur in 60° Rotationswinkelschritten am Plastifizierzylinder befestigen oder lösen lassen. Maschinenbedienern wird die Handhabung der Düsen bei engen Platzverhältnissen im Düseneinbauraum zwischen dem Plastifizierzylinder und der Spritzgieß- oder Extrudierform an bzw. in Standard-Kunststoffverarbeitungsmaschinen dadurch sehr erschwert.The disadvantage is that the nozzles can thereby fix or release only in 60 ° rotation angle steps on plasticizing. Machine operators, the handling of the nozzles in tight space conditions in the nozzle installation space between the plasticizing and injection molding or extrusion on or in standard plastic processing machines is very difficult.
Alle bekannten Düsen haben einen zentralen Düsenkanal um den Volumenstrom der Kunststoffschmelze im zentralen Düsenkanal im Durchmesser zu reduzieren. Durch die damit geometrisch vorbestimmte Durchmesserreduktion ist für jeden Innendurchmesser eines Plastifizierzylinders eine an den jeweiligen Innendurchmesser des Plastifizierzylinders angepasste Düse erforderlich.All known nozzles have a central nozzle channel to reduce the volume flow of the plastic melt in the central nozzle channel in diameter. By thus geometrically predetermined diameter reduction, a nozzle adapted to the respective inner diameter of the plasticizing cylinder is required for each inner diameter of a plasticizing cylinder.
Aufgabe der Erfindung ist es, eine Düse mit einer Aufnahme für Schmelzeaufbereitungselemente zum Anschluss an einen Plastifizierzylinder einer Standard-Kunststoffverarbeitungsmaschine zu schaffen, die derart ausgebildet ist, dass diese durch eine kurze Baulänge und leichte Handhabung schnell gegen Standarddüsen herkömmlicher Bauart austauschbar ist und zum Anschluss an Plastifizierzylinder mit unterschiedlichen Innendurchmessern leicht umgerüstet werden kann.The object of the invention is to provide a nozzle with a receptacle for melt processing elements for connection to a plasticizing a standard plastic processing machine, which is designed such that it is quickly replaced by a short length and easy handling against standard nozzles of conventional design and for connection to Plasticizing cylinder with different inner diameters can be easily converted.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Hauptanspruchs gelöst. Ausgestaltungen der Erfindung sind in den Unteransprüchen dargestellt.According to the invention the object is achieved by the features of the main claim. Embodiments of the invention are shown in the subclaims.
Der Vorteil der Erfindung besteht darin, dass durch einen austauschbaren Düsenring die Düse sehr schnell auf verschiedene Plastifizierzylinder mit unterschiedlichen Innendurchmessern innerhalb einer Baugruppe angepasst werden kann und dass die Düse selbst eine kurze Baulänge hat, so dass sie in Standard-Kunststoffverarbeitungsmaschinen gegen Standarddüsen herkömmlicher Bauart sehr leicht ausgetauscht werden kann.The advantage of the invention is that the nozzle can be adapted very quickly to different plasticizing with different inner diameters within an assembly by a replaceable nozzle ring and that the nozzle itself has a short length, so that in standard plastic processing machines against standard nozzles of conventional design very can be easily replaced.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher erläutert. Die dazugehörige Zeichnung zeigtThe invention will be explained in more detail with reference to an embodiment. The accompanying drawing shows
Letztlich zeigt
Der dadurch erreichte besondere Vorteil gegenüber dem Stand der Technik, bei dem alle bekannten Düsen mit Außensechskant für einen Werkzeugeingriff ausgestattet sind, ist die erheblich erleichterte Handhabung bei engen Platzverhältnissen im Düseneinbauraum zwischen dem Plastifizierzylinder und der Spritzgieß- oder Extrudierform an bzw. in Standard-Kunststoffverarbeitungsmaschinen.The achieved thereby special advantage over the prior art, in which all known nozzles are equipped with external hexagon for a tool engagement, the much easier handling in tight spaces in the nozzle installation space between the plasticizing and injection molding or extrusion on or in standard plastic processing machines ,
