Abstract

In a mixing head of which the mixing chamber is adjoined by a smoothing chamber at an angle of preferably 90 DEG , a throttle element is proposed, having a shaping effect and a displaceability in the longitudinal direction of the mixing chamber such that it can be moved through the smoothing chamber to in front of or into the outlet opening of the mixing chamber, to be precise optionally to a greater or lesser extent, thus achieving a mixing chamber with variable outlet gap (throttle gap), if required with variable volume. The mixing conditions of the components used and the throttling of the mixture emerging from the mixing chamber can thus be influenced.

Description

Die Erfindung betrifft einen HischkopS nach dem Ober-The invention relates to a HischkopS after the upper

begriff des inspruchs 1 (vgl. DZ POS 31 20 482). Es ist bei einem solchen Hochdruck-Mischkopf bekannt, zur Steuerung des Druckes in der Miechkammer und zur guten Dosierung auch bei kleinen Austragleistungen (wenige Gramm Gemisch pro Hischphase) bewegliche Staukörper vorzusehen, und zwar in der Mischkammer selbst (vgl. DE-PS 20 65 841, DE-AS 26 12 812) oder hinter der Mischkammer in einem Angießkanal (vgl.term of claim 1 (see DZ POS 31 20 482). It is with one such high-pressure mixing head known for controlling the pressure in the Miechkammer and for good dosing even with small discharge capacities (a few grams of mixture movable baffles are to be provided for each mixing phase, namely in the mixing chamber itself (See. DE-PS 20 65 841, DE-AS 26 12 812) or behind the mixing chamber in a sprue (see.

DE-AS 25 44 749).DE-AS 25 44 749).

Diese Ausführungen sind im Hinblick auf die Erzeugung der Mischung in der Mischkammer und die Strömungsverhältnisse des Gemischs noch nicht voll befriedigend.These explanations are with regard to the creation of the mixture in the mixing chamber and the flow conditions of the mixture are not yet fully satisfactory.

Der Erfindung liegt daher eine Verbesserung in dieser Hinsicht zugrunde Gelöst wird diese Aufgabe durch die Maßnahme nach dem Kennzeichen des Anspruchs 1. Dadurch, daß das Drosselorgan erfindungsgemäß unmittelbar vor die Mischkammeraustrittsöffnung herangefahren bzw. von einem Ende teilweise in die Mischkammer hineingefahren wird, wird nicht nur eine zweckmäßige, in Grenzen veränderbare Drosselung des aus der Mischkammer austretenden Gemisches erreicht, wobei die Blasenfreiheit des Gemischer hervorzuheben ist, sondern beim Hineinfahren auch Einfluß auf die Größe der Mlschkammer und damit auf die ischungsbedingungen genommen, was insbesondere bei m ischungsunwilligenKomponenten von Bedeutung ist.The invention is therefore based on an improvement in this regard This problem is solved by the measure according to the characteristic of the claim 1. Characterized in that the throttle element according to the invention is immediately in front of the mixing chamber outlet opening is approached or partially moved into the mixing chamber from one end, is not only an expedient, adjustable within limits throttling of the Mixing chamber reached the exiting mixture, the absence of bubbles in the mixture should be emphasized, but also has an influence on the size of the mash chamber when entering and thus taken on the mixing conditions, which is especially true for components that are unwilling to mix matters.

Nach Anspruch 2 ergibt sich ein ringsherum gleich großer Drosselspalt zwischen der Wand der Mischkammeraustrittsöffnung und dem Drosselorgan. Eine solche Ausführung wirkt sich strömungsgünstig auf die Mischkammer und den sich daran anschließenden Kanal aus.According to claim 2 there is a throttle gap of the same size all around between the wall of the mixing chamber outlet opening and the throttle element. Such Execution has a flow-favorable effect on the mixing chamber and the adjoining it Channel off.

Anspruch 3 zeigt, daß das Drosselorgan dazu dienen kann, einen weiteren Stoff in die Mischkammer einzuführen und insofern die Nischungsmöglichkeiten zu verbessern.Claim 3 shows that the throttle member can be used to further Introduce substance into the mixing chamber and in this respect the niche possibilities to enhance.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert. Die einzige Figur zeigt einen Mischkopf in einem Längsmittelschnitt.An embodiment of the invention is described below with reference to the Drawing explained. The single figure shows a mixing head in a longitudinal center section.

In einer Mischkammer 1 zum Erzeugen eines Polyurethangemisches aus zwei Kunststoffkomponenten ist ein längs der Mischkammerachse verschiebbares Steuerorgan 2 angeordnet. Dieses am rechten Ende als Kolben 3 ausgebildete Steuerorgan 2 wird von einer Kolben-Zylinderanordnung 4 betätigt, die an der der Mischkammeraustrittsöffnung 5 entgegengesetzten Seite angeordnet ist.In a mixing chamber 1 for producing a polyurethane mixture two plastic components is a control member that can be displaced along the axis of the mixing chamber 2 arranged. This control member 2, designed as a piston 3 at the right end, is actuated by a piston-cylinder arrangement 4, which is located at the mixing chamber outlet opening 5 opposite side is arranged.

Der Kolben 3 gibt in der hinteren Endlage (dargestellt) mit seiner Stirnfläche 7 den Zugang der Eintrittsöffnungen 8, 9 für die Kunststoffkomponenten zur Mischkammer 1 frei. In der anderen, vorderen Endlage verschließt der Kolben 3 die Eintrittsöffnungen 8, 9 im Hinblick auf die Mischkammer 1 und die Mischkammeraustrittsöffnung 5. Im Mantel des Kolbens 3 sind Uberströmkanäle 21, 22 eingearbeitet, die in der vorderen Endlage des Kolbens 3 die Eintrittsöffnungen 8, 9 mit voneinander getrennt im Mischkammergehäuse 6 angeordneten Rückführleitungen 10, 11 verbinden.The piston 3 is in the rear end position (shown) with his End face 7 the access of the inlet openings 8, 9 for the plastic components to the mixing chamber 1 free. In the other, front end position, the piston closes 3 the inlet openings 8, 9 with regard to the mixing chamber 1 and the mixing chamber outlet opening 5. In the jacket of the piston 3 overflow channels 21, 22 are incorporated, which in the front end position of the piston 3, the inlet openings 8, 9 separated from each other Connect return lines 10, 11 arranged in the mixing chamber housing 6.

In einem Winkel von 90° zur Längsrichtung der Mischkammer 1 und unmittelbar hinter deren Mischkammeraustrittsöffnung 5 ist ein Kanal 12 zur Beruhigung des in der Mischkammer 1 durch Injektion erzeugten und turbulent in den Kanal 12 eintretenden Kunststoffgemisches angeordnet. Dieser mündet in hier nicht weiter gezeigten Weise frei über dem Hohlraum einer offenen Form oder ist an den Hohlraum einer geschlossenen Form oder an eine zu einer Form führenden Zuleitung angeschlossen. Die Stirnfläche 7 des Kolbens 3 ist der Form der Wandung des Kanals 12 angepaßt, so daß sich in der vorderen Endstellung des Kolbens 3 eine glatte Wand des Kanals ergibt In- dem Kanal 12 ist ein Reinigungsstempel 14 so längsbewegbar5 daß er in der einen Endstellung mit seinem unteren Ende die Mischkammeraustrittsöffnung 5 ganz freigibt und diese auf seinem Wege bis zum Erreichen der Kanalaustrittsöffnung 17 abschließt. Dadurch, daß beide Kolben 3 und 14 in ihren vorderen Endlagen eine zumindest bündige Stellung zu der Austrittsöffnung 5 bzw. 17 einnehmen können, wird nach jedem Misch-und Füllvorgang das Verbleiben von Mischungsresten in der Mischkammer 1 und im Kanal 12 verhindert. Der Reinigungsstempel 14 wird von einem Arbeitskolben 13 betätigt, der koaxial zu einem den Reinigungsstempel 14 aufnehmenden Gehäuseteil 20 festgelegt und in einem weiteren Gehäuseteil 19 geführt ist.At an angle of 90 ° to the longitudinal direction of the mixing chamber 1 and directly behind the mixing chamber outlet opening 5 is a channel 12 for calming the in the mixing chamber 1 generated by injection and entering the channel 12 in a turbulent manner Plastic mixture arranged. This ends in a manner not shown here freely above the cavity one open shape or is attached to the cavity a closed form or connected to a lead leading to a form. The end face 7 of the piston 3 is adapted to the shape of the wall of the channel 12, so that in the front end position of the piston 3 there is a smooth wall of the channel In the channel 12, a cleaning ram 14 can be moved longitudinally in such a way that it is in the one end position with its lower end the mixing chamber outlet opening 5 completely releases and this on its way to reaching the channel outlet opening 17 completes. The fact that both pistons 3 and 14 in their front end positions a can take at least a flush position to the outlet opening 5 and 17, respectively after each mixing and filling process, the remaining mixture residues in the mixing chamber 1 and in channel 12 prevented. The cleaning ram 14 is supported by a working piston 13 actuated, the coaxial to a housing part receiving the cleaning ram 14 20 is set and guided in a further housing part 19.

Ein weiterer Gehäuseteil 18 - die Gehäuseteile 18 bis 20 sind aus Vereinfachungsgründen als zusammenhängendes Gehäuse gezeichnet - nimmt einen weiteren Kolben, den Drosselkolben 159 auf, an den sich in Richtung der Mischkammer 1 ein Verbindungsstück 23 mit einem Drosselorgan 24 am linken Ende und in der anderen Richtung eine Gewindestange 16 anschließt. In der gezeichneten Stellung ist das Drosselorgan 24 durch die Mischkammeraustrittsöffnung 5 teilweise in die Mischkammer 1 eingeschoben, wodurch die Mischkammeraustrittsöffnung 5 nicht in ihrem vollen Querschnitt zur Verfügung steht, sondern das Gemisch lediglich über einen Ringspalt 25 in den Kanal 12 eintreten kann. Dadurch wird eine vorteilhafte Drosselwirkung erzielt; außerdem ist das Volumen der Mischkammer durch die Stellung des Drosselorgans 24 steuerbar. Diese Steuerung erfolgt von Hand über die Gewindestange 16, auf dessen Gewindeteil 26 zwei Muttern 27, 28 verstellbar sind und gegeneinander festgezogen werden können.Another housing part 18 - the housing parts 18 to 20 are made of For the sake of simplicity, drawn as a coherent housing - takes another Piston, the throttle piston 159, to which a in the direction of the mixing chamber 1 Connector 23 with a throttle member 24 at the left end and in the other Direction a threaded rod 16 connects. This is in the position shown Throttle member 24 through the mixing chamber outlet opening 5 partially into the mixing chamber 1 inserted, whereby the mixing chamber outlet opening 5 is not in its full Cross-section is available, but the mixture only through an annular gap 25 can enter the channel 12. This creates a advantageous Throttling effect achieved; in addition, the volume of the mixing chamber is determined by the position of the throttle member 24 controllable. This control is done by hand via the threaded rod 16, on the threaded part 26 of which two nuts 27, 28 are adjustable and against each other can be tightened.

Die Kolben 4, 13 und 15 werden von Druckmitteln beaufschlagt und damit betätigt, die über Bohrungen 29 bis 34 ein- bzw. austreten. Es liegt auf der Hand, daß - wie bei Drosselorganen in Mischköpfen üblich - die Steuerung so ausgestaltet ist, daß der Reinigungsstempel 14 erst dann den Kanal 12 von den Gemischresten reinigen kann, wenn das Drosselorgan 24 so weit nach rechts zurückgefahren ist, daß der Querschnitt des Kanals 12 freigegeben ist. Der Teil,der aus der Gewindestange 16, dem Drosselkolben 15, dem Verbindungsstück 23 und dem Drosselorgan 24 besteht, weist eine Längsbohrung 35 auf, die am rechten Ende in eine flexible Leitung 36 übergeht. Damit können auf einfache, aber wirkungsvolle Weise weitere Stoffe, z.B. Farbzusätze, dem Gemisch aus den Kunststoffkomponenten beigemischt werden.The pistons 4, 13 and 15 are acted upon by pressure means and thus actuated, which enter or exit via bores 29 to 34. It is obvious, that - as usual with throttling devices in mixing heads - the control is designed in such a way is that the cleaning ram 14 only then clean the channel 12 of the mixture residues can when the throttle member 24 is moved back so far to the right that the cross-section of the channel 12 is released. The part that consists of the threaded rod 16, the throttle piston 15, the connecting piece 23 and the throttle member 24 has a longitudinal bore 35, which merges into a flexible line 36 at the right end. So can on simple but effective way to add other substances, e.g. color additives, to the mixture are added from the plastic components.

Es gehört zur Erfindung, daß das Drosselorgan 23 lediglich bis vor die Mischkammeraustrittsöffnung 5 verfahren wird, wobei der Durchmesser des Drosselorgans 23 auch so groß wie der Durchmesser der Mischkammer 1 oder sogar größer sein kann. Ferner wird das vordere Ende des Drosselorgans 24 zweckmäßigerweise - wie die Stirnfläche 7 - an die Form des Kanals 12 angepaßt.It is part of the invention that the throttle member 23 only up to before the mixing chamber outlet opening 5 is moved, the diameter of the throttle member 23 can also be as large as the diameter of the mixing chamber 1 or even larger. Furthermore, the front end of the throttle member 24 is expediently - like the end face 7 - adapted to the shape of the channel 12.
