Description

Die Erfindung betrifft ein Druckgusswerkzeug einer Druckgussmaschine, mit einer ersten Form, die ein erstes und ein zweites Formteil aufweist, welche zum Formschließen und Formöffnen linear zueinander verfahrbar sind und zwischen sich mindestens eine Formkavität bilden, und mit mindestens einem Gießlauf. Druckgusswerkzeuge der eingangs genannten Art sind bekannt. Sie werden in einer Druckgussmaschine eingesetzt. Zum Befüllen (Schuss) der Formkavität wird über den Gießlauf ein heißes, flüssiges Medium, beispielsweise ein Metall, eine Metalllegierung oder Kunststoff, über den Gießlauf angebracht. Zuvor muss die aus einem ersten und einem zweiten Formteil bestehende Form geschlossen werden. Ist das Medium in der Gießkammer und der Formkavität erstarrt, so werden die beiden Formteile auseinandergefahren. Aufgrund dieser Vorgehensweise ist die Anzahl der pro Zeiteinheit herstellbaren Werkstücke begrenzt. Um die Anzahl der Werkstücke zu erhöhen, können in den beiden Formteilen mehrere Gießvertiefungen zur Ausbildung mehrerer Formkavitäten vorhanden sein. Die dafür zur Verfügung stehende Fläche ist aufgrund der zu handhabenden Materialien, dem aufzubringenden Formschließdruck und so weiter jedoch begrenzt.The invention relates to a die-casting tool of a die-casting machine, having a first mold, which has a first and a second mold part, which are linearly movable relative to each other for mold closing and mold opening and form at least one mold cavity between them, and at least one casting run. Diecasting tools of the type mentioned are known. They are used in a die casting machine. For filling (shot) of the mold cavity, a hot, liquid medium, for example a metal, a metal alloy or plastic, is placed over the run over the runner. Previously, the form consisting of a first and a second molded part must be closed. If the medium in the casting chamber and the mold cavity solidifies, the two mold parts are moved apart. Due to this procedure, the number of workpieces producible per unit time is limited. In order to increase the number of workpieces, several casting depressions for forming a plurality of mold cavities may be present in the two mold parts. However, the area available for this is limited due to the materials to be handled, the mold closing pressure to be applied and so on.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Druckgusswerkzeug einer Druckgussmaschine zu schaffen, das eine sehr hohe Fertigungskapazität aufweist, das heißt, es können pro Zeiteinheit eine Vielzahl von Gusswerkstücken erstellt werden.The invention is therefore an object of the invention to provide a die-casting tool of a die-casting machine, which has a very high Having manufacturing capacity, that is, it can be created per unit of time a variety of castings.

Diese Aufgabe wird erfindungsgemäß durch mindestens eine weitere, zweite Form gelöst, die ein drittes und ein viertes Formteil aufweist, welche zum Formschließen und Formöffnen gleichgerichtet zu den Formteilen der ersten Form linear zueinander verfahrbar sind und zwischen sich mindestens eine weitere Formkavität bilden, wobei ein Formteil der ersten Form und ein Formteil der zweiten Form Rücken zu Rücken zueinander angeordnet sind und zwischen sich ein Zwischenelement aufnehmen, das den Gießlauf aufweist. Durch diese Ausgestaltung ergibt sich quasi ein Etagendruckgusswerkzeug, das heißt, die mindestens zwei Formen sind etagenförmig zueinander angeordnet, wobei hier ein Übereinander- oder ein Nebeneinanderanordnen der Formen gemeint ist. Mit ein und derselben Druckgussmaschine werden daher mehrere Formen gleichzeitig verwendet, sodass sich eine entsprechende Erhöhung der Produktivität einstellt. Die Erfindung ist nicht auf zwei Formen begrenzt, sondern es können etagenmäßig auch mehr als zwei Formen in Übereinander- und/oder Nebeneinanderbauweise eingesetzt werden. Die Anordnung ist dabei derart getroffen, dass zum Öffnen der jeweiligen Form mindestens eines der zugehörigen Formteile linear verlagert wird. Diese Linearbewegung erfolgt quer, insbesondere rechtwinklig, zu einer Formtrennebene. Mithin werden die einzelnen Etagen des mehrere Formen aufweisenden Druckwerkzeugs zum Formöffnen linear in der genannten Art und Weise verfahren und zum Formschließen in die entsprechende Gegenrichtung linear verlagert. Das Verfahren und die Verlagerungsbewegung erfolgt stets - wie bereits erwähnt - quer, insbesondere rechtwinklig zu den einzelnen Formtrennebenen der Formen, wobei die Formtrennebenen zwischen den beiden Formteilen der jeweiligen Form liegen. Um das erfindungsgemäße Druckgusswerkzeug mit einem Medium, beispielsweise mit einer flüssigen Metalllegierung, befüllen zu können, ist zwischen den mindestens zwei Formen ein Zwischenelement angeordnet, das den Gießlauf aufweist. Über den Gießlauf werden die mindestens zwei Formkavitäten der mindestens beiden Formen befüllt. Für ein Entformen der hergestellten Werkstücke werden die Formen nach Verfestigung des Mediums durch lineares Auseinanderfahren geöffnet. Durch die erwähnte Etagenbauweise des erfindungsgemäßen Druckgusswerkzeugs ist auch nur ein sehr geringer Platzbedarf bei einem Betreiben notwendig, da die beiden Formen lediglich eine Antriebs- und Abstützvorrichtung der Druckgussmaschine benötigen. Im Stand der Technik ist es für den Betrieb zweier Formen erforderlich, zwei Druckgussmaschinen einzusetzen, die demzufolge einen erheblich größeren Platzbedarf beanspruchen.This object is achieved by at least one further, second mold having a third and a fourth mold part, which are rectilinear for form closing and mold opening to the mold parts of the first form linearly movable and form between them at least one further mold cavity, wherein a molded part the first mold and a mold part of the second mold are arranged back to back to each other and receive between them an intermediate element having the runner. As a result of this embodiment, a floor pressure die casting tool is obtained, that is to say, the at least two shapes are arranged in the form of a tier, wherein superimposition or juxtaposition of the forms is meant here. With the same die casting machine, therefore, multiple molds are used simultaneously, so that a corresponding increase in productivity sets. The invention is not limited to two forms, but it can also be used in terms of floor and more than two forms in superimposed and / or side-by-side construction. The arrangement is made such that at least one of the associated mold parts is linearly displaced to open the respective mold. This linear movement takes place transversely, in particular at right angles, to a mold parting plane. Consequently, the individual levels of the printing tool having a plurality of molds are moved linearly in the manner mentioned for form opening and are linearly displaced in the corresponding opposite direction for form closing. The method and the displacement movement is always - as already mentioned - transversely, in particular at right angles to the individual mold parting planes the molds, wherein the mold parting planes are between the two mold parts of the respective mold. In order to be able to fill the diecasting tool according to the invention with a medium, for example with a liquid metal alloy, an intermediate element which has the casting run is arranged between the at least two molds. About the casting the at least two mold cavities of the at least two forms are filled. For demolding of the produced workpieces, the molds are opened after solidification of the medium by linear separation. Due to the mentioned stack construction of the die-casting tool according to the invention, only a very small amount of space is required for operation, since the two forms require only one drive and support device of the die-casting machine. In the prior art, it is necessary for the operation of two molds to use two die casting machines, which consequently require a much larger footprint.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Gießlauf zu beiden Formkavitäten führt. Mithin kann über einen Gießlauf die Befüllung beider Formkavitäten erfolgen. Die Erfindung ist selbstverständlich nicht auf zwei Formkavitäten beschränkt, sondern jede der mindestens zwei Formen kann mehrere Formkavitäten aufweisen.According to a development of the invention, it is provided that the casting run leads to both mold cavities. Consequently, the filling of both mold cavities can take place via a casting run. Of course, the invention is not limited to two mold cavities, but each of the at least two molds may have a plurality of mold cavities.

Bevorzugt ist vorgesehen, dass dem Zwischenelement eine Abschervorrichtung zum Abscheren mindestens eines Angusses, vorzugsweise eines beide Formen betreffenden Angusses, zugeordnet ist. Im Bereich des Zwischenelements, also in der Zone zwischen den mindestens zwei Formen befindet sich die Abschervorrichtung.It is preferably provided that the intermediate element is associated with a shearing device for shearing off at least one sprue, preferably a sprue of both shapes. In the region of the intermediate element, that is to say in the zone between the at least two forms, the shearing device is located.

Sie schert den im Gießlauf ausgebildeten Anguss ab. Besonders effektiv ist es, wenn eine Abschervorrichtung den Anguss beider Formen abschert, wobei vorzugsweise ein gemeinsamer Anguss für die Formen vorliegt, der von der Abschervorrichtung abgetrennt wird.It shears off the runner formed in the run. It is particularly effective if a shearing device shears off the sprue of both forms, wherein there is preferably a common sprue for the shapes which is separated from the shearing device.

Die Abschervorrichtung weist bevorzugt ein linear verfahrbares Abschermesser auf, wobei die Verfahrrichtung des Abschermessers quer, insbesondere rechtwinklig zu den linearen Verfahrrichtungen der Formteile verläuft. Durch diese Anordnung ist der Bauraum der Gesamtanordnung optimal genutzt, wobei die Bewegungsfreiräume für die Formteile und das Abschermesser winklig, insbesondere rechtwinklig aufeinander stehen.The shearing device preferably has a linearly movable shearing knife, wherein the traversing direction of the shearing knife extends transversely, in particular at right angles to the linear traversing directions of the shaped parts. By this arrangement, the space of the overall arrangement is used optimally, wherein the freedom of movement for the mold parts and the shearing blade angle, in particular at right angles to each other.

Nach einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass das Zwischenelement mindestens zwei Auswerfervorrichtungen für die beiden Formen aufweist. Im Zwischenelement sind demzufolge auch die Auswerfmittel untergebracht, um die mindestens zwei Formen zu leeren. Die Auswerfervorrichtungen befinden sich demzufolge platzoptimiert zwischen den beiden Formen.According to a preferred embodiment of the invention it is provided that the intermediate element has at least two Auswerfervorrichtungen for the two forms. Consequently, the ejection means are also accommodated in the intermediate element in order to empty the at least two molds. The Auswerfervorrichtungen are therefore space-optimized between the two forms.

Die Auswerfervorrichtungen weisen Auswerfzylinder, insbesondere Blockzylinder auf, die seitlich der Formteile angeordnet sind, die an das Zwischenelement angrenzen. Seitlich neben den dem Zwischenelement zugeordneten Formteilen wird daher der Raum zur Positionierung der Auswerfzylinder der Auswerfervorrichtungen genutzt. Hier treten die Auswerfzylinder nicht störend in Erscheinung und nutzen einen sonst brachliegenden Bauraum.The ejector devices have ejector cylinders, in particular block cylinders, which are arranged laterally of the molded parts, which adjoin the intermediate element. The space for positioning the Auswerfzylinder the Auswerfervorrichtungen is therefore used laterally adjacent to the intermediate element associated moldings. Here, the ejector cylinders do not appear disturbing and use an otherwise unused space.

Das Zwischenelement weist bevorzugt zwei Zwischenelementteile auf, die Rücken an Rücken zueinander angeordnet sind. Jedes Zwischenelementteil ist einer der beiden Formen zugeordnet.The intermediate element preferably has two intermediate element parts, which are arranged back to back to each other. Each intermediate element part is assigned to one of the two forms.

Eine Weiterbildung der Erfindung sieht vor, dass das erste Formteil der ersten Form ein festes Formteil ist, zu dem - zum Formschließen und Formöffnen der ersten Form - eine aus dem ersten Formteil der ersten Form, dem Zwischenelement und dem dritten Formteil der zweiten Form bestehende Einheit linear verfahrbar ist und dass zu der Einheit - zum Formschließen und Formöffnen der zweiten Form - das vierte Formteil linear verfahrbar ist. Zum Formöffnen und Formschließen behält das erste Formteil der ersten Form seine Position bei, es handelt sich deshalb um ein festes Formteil. Sollen die Formen geöffnet werden, so erfolgt ein lineares Verfahren der Einheit, die aus dem zweiten Formteil der ersten Form, dem Zwischenelement und dem dritten Formteil der zweiten Form besteht. Gleichzeitig, vorher oder danach verfährt zum Öffnen der zweiten Form das vierte Formteil entlang eines linearen Weges. Sind mehr als zwei Formen etagenmäßig angeordnet, so gelten die vorstehenden Ausführungen entsprechend.A development of the invention provides that the first mold part of the first mold is a solid mold part, to which - for mold closing and mold opening of the first mold - a unit consisting of the first mold part of the first mold, the intermediate element and the third mold part of the second mold is linearly movable and that to the unit - for mold closing and mold opening of the second mold - the fourth molding is linearly movable. For opening and closing the mold, the first mold part of the first mold retains its position, which is why it is a solid mold part. If the molds are to be opened, then a linear process of the unit, which consists of the second mold part of the first mold, the intermediate element and the third mold part of the second mold. At the same time, before or after, the fourth mold part is moved along a linear path to open the second mold. If more than two shapes are arranged on the floor, the above statements apply accordingly.

Insbesondere weist das erste Formteil einen festen, auswechselbaren Formeinsatz auf und das zweite, dritte und vierte Formteil besitzen fahrende, auswechselbare Formeinsätze. Alle Formeinsätze sind auswechselbar, um unterschiedliche Werkstücke herstellen zu können, jedoch weist das erste Formteil einen festen Formeinsatz auf, weil dieser seine Position beim Betrieb des Druckgusswerkzeugs nicht ändert. Das Wort "fest" bezieht sich daher auf die ortsfeste Positionierung. Die übrigen Formteile weisen fahrende Formeinsätze auf, weil sich die Formteile und damit auch die ihnen zugehörigen Formeinsätze beim Schließen und Öffnen der jeweiligen Form bewegen, also ihre Positionen ändern.In particular, the first molded part has a fixed, interchangeable mold insert and the second, third and fourth molded parts have moving, interchangeable mold inserts. All mold inserts are interchangeable to produce different workpieces, however, the first mold part has a fixed mold insert, because this does not change its position during operation of the die-casting tool. The word "fixed" therefore refers to the fixed positioning. The remaining moldings have moving mold inserts on, because the moldings and thus their associated mold inserts move when closing and opening the respective shape, so change their positions.

Schließlich ist es vorteilhaft, wenn eine feststehende Aufspannplatte und eine dazu über Führungssäulen linear verfahrbare, bewegliche Aufspannplatte vorgesehen ist, wobei zwischen den beiden Aufspannplatten mindestens die beiden Formen und mindestens das eine Zwischenelement angeordnet sind. Die beiden Aufspannplatten halten das aus den Formteilen und dem Zwischenelement bestehende Etagenpaket in der Schließstellung der Formen zusammen und sie fahren auseinander, um die Formen zu öffnen. Sofern mehr als zwei Formen vorhanden sind, ist auch mehr als ein Zwischenelement notwendig, da sich jeweils zwischen zwei Formen ein Zwischenelement befindet.Finally, it is advantageous if a fixed platen and a linearly movable over guide columns movable platen is provided, wherein between the two platen at least the two molds and at least one intermediate element are arranged. The two platens hold the stack of packages consisting of the mold parts and the intermediate element in the closed position of the molds and they move apart to open the molds. If more than two forms are present, more than one intermediate element is necessary because there is an intermediate element between each two forms.

Die Figur 1 zeigt ein Druckgusswerkzeug 1 in einer nicht näher gezeigten Druckgussmaschine, das eine erste Form 2, eine zweite Form 3 sowie ein zwischen den beiden Formen 2 und 3 angeordnetes Zwischenelement 4 aufweist. Die erste Form 2 weist ein erstes Formteil 5 und ein zweites Formteil 6 auf. Die zweite Form weist ein drittes Formteil 7 und ein viertes Formteil 8 auf. Das Zwischenelement 4 setzt sich aus zwei Zwischenelementteilen 9 und 10 zusammen. Die jeweils plattenförmig ausgebildeten Formteile 5 bis 8 und Zwischenelementteile 9 und 10 liegen - hochkant stehend - flächig aneinander, wobei das erste Formteil 5 am zweiten Formteil 6 anliegt, das zweite Formteil 6 am Zwischenelementteil 9 anliegt, das Zwischenelementteil 9 am Zwischenelementteil 10, das Zwischenelementteil 10 am dritten Formteil 7 und das dritte Formteil 7 am vierten Formteil 8. Zwischen den jeweils vorstehend genannten Teilen wird jeweils eine Trennebene ausgebildet, wobei die Trennebenen parallel zueinander verlaufen und im dargestellten Ausführungsbeispiel vertikal stehen. Das erste Formteil 5 wird von einer feststehenden Aufspannplatte 11 beaufschlagt, von der Führungssäulen 12, 13 ausgehen, auf denen linear längsverschieblich eine bewegliche Aufspannplatte 14 lagert, wobei zwischen den beiden Aufspannplatten 11 und 14 die beiden Formen 2 und 3 sowie das Zwischenelement 4 angeordnet sind. Mittels einer nicht näher dargestellten Antriebsvorrichtung lassen sich die Formen 2 und 3 sowie das Zwischenelement 4 mittels der Aufspannplatten 11 und 14 miteinander stapelförmig verspannen. Dies führt dazu, dass die Formteile 5 und 6 sowie 7 und 8 aufeinandergebracht werden, sodass ein Schließzustand der Formen 2 und 3 vorliegt. Zwischen den Formelementen 5 und 6 beziehungsweise 7 und 8 ist jeweils mindestens eine Formkavität ausgebildet, sodass - entsprechend der Anzahl der ausgebildeten Formkavitäten - eine entsprechende Anzahl von Werkstücken durch Einbringen eines heißen, erstarrenden Mediums in einem Füllkanal 15 hergestellt werden können. Der Füllkanal 15 führt zu einem zwischen den beiden Zwischenelementteilen 9 und 10 verlaufenden Gießlauf 16 (Figur 2), sodass das Medium über entsprechend Gusskanäle bis in die Formkavitäten strömen kann. Nach dem Verfestigen der auf diese Art und Weise erzeugten Werkstücke werden die Formen 2 und 3 gemäß Figur 2 geöffnet. Hierzu verfährt eine aus dem Formteil 6, dem Zwischenelement 4 und dem Formteil 7 bestehende Einheit 17 derart entlang der Führungssäulen 12 und 13, dass sich die Formteile 5 und 6 trennen. Ferner verfährt die Aufspannplatte 14 zusammen mit dem Formteil 8 derart, dass sich die Form 3 öffnet (Figur 2).The FIG. 1 shows a die-casting tool 1 in a die-casting machine not shown in detail, which has a first mold 2, a second mold 3 and an intermediate element 4 arranged between the two molds 2 and 3. The first mold 2 has a first molded part 5 and a second molded part 6. The second mold has a third mold part 7 and a fourth mold part 8. The intermediate element 4 is composed of two intermediate element parts 9 and 10. The respective plate-shaped moldings 5 to 8 and intermediate element parts 9 and 10 are - standing upright - surface to each other, wherein the first mold part 5 abuts the second mold part 6, the second mold part 6 rests on the intermediate element part 9, the intermediate element part 9 on the intermediate element part 10, the intermediate element part 10 on the third mold part 7 and the third mold part 7 on the fourth mold part 8. Between each of the above-mentioned parts in each case a parting plane is formed, wherein the parting planes parallel to each other and are vertical in the illustrated embodiment. The first mold part 5 is acted upon by a fixed platen 11, from the guide columns 12, 13 go out, on which linearly longitudinally displaceable a movable platen 14 superimposed, wherein between the two Platen 11 and 14, the two molds 2 and 3 and the intermediate element 4 are arranged. By means of a drive device, not shown, the molds 2 and 3 and the intermediate element 4 by means of the clamping plates 11 and 14 clamped together stack-shaped. As a result, the mold parts 5 and 6 and 7 and 8 are brought onto each other, so that a closed state of the molds 2 and 3 is present. In each case at least one mold cavity is formed between the mold elements 5 and 6 or 7 and 8, so that - corresponding to the number of mold cavities formed - a corresponding number of workpieces can be produced by introducing a hot, solidifying medium in a filling channel 15. The filling channel 15 leads to a running between the two intermediate element parts 9 and 10 casting run 16 ( FIG. 2 ), so that the medium can flow through corresponding casting channels into the mold cavities. After solidification of the workpieces produced in this way, the molds 2 and 3 according to FIG. 2 open. For this purpose, a unit consisting of the molded part 6, the intermediate element 4 and the molded part 7 moves along the guide columns 12 and 13 in such a way that the molded parts 5 and 6 separate. Furthermore, the clamping plate 14 moves together with the molding 8 such that the mold 3 opens ( FIG. 2 ).

Die Figur 3 zeigt den vollständig auseinandergefahrenen Zustand. Die Abstände zwischen den Formteilen 5 und 6 einerseits und 7 und 8 andererseits sind derart groß, dass eine Entformung der erzeugten Werkstücke 18 problemlos erfolgen kann.The FIG. 3 shows the completely disassembled state. The distances between the mold parts 5 and 6 on the one hand and 7 and 8 on the other hand are so large that a demolding of the produced workpieces 18 can be done easily.

Aus den Figuren 1 bis 3 ist erkennbar, dass die beiden Formen 2 und 3 unter Zwischenschaltung des Zwischenelements 4 stapelförmig angeordnet sind. Da das Medium mittels des Zwischenelements 4 in die beiden Formen 2 und 3 eingebracht wird, lassen sich diese aufgrund der Zwischenposition des Zwischenelements 4 gleichzeitig und von nur dem einen Gießlauf 16 beschicken. Ferner weist das Zwischenelement 4 Auswerfervorrichtungen 19 und 20 auf, wobei die Auswerfvorrichtung 19 den Zwischenelementteil 9 und die Auswerfvorrichtung 20 dem Zwischenelementteil 10 zugeordnet ist. Im Bereich des Zwischenelements 4 ist - gemäß Figur 1 - ferner eine Abschervorrichtung 21 (in den Figuren 2 und 3 nicht dargestellt) angeordnet, die dem Abscheren eines Angusses dient. Hierbei handelt es sich um das erstarrte Medium im Gießlauf 16. Nachstehend wird hierauf noch näher eingegangen.From the FIGS. 1 to 3 It can be seen that the two molds 2 and 3 are arranged in stack form with the interposition of the intermediate element 4. Since the medium is introduced into the two molds 2 and 3 by means of the intermediate element 4, they can be charged simultaneously and only by the one run 16 due to the intermediate position of the intermediate element 4. Furthermore, the intermediate element 4 has ejection devices 19 and 20, the ejection device 19 being assigned to the intermediate element part 9 and the ejection device 20 to the intermediate element part 10. In the area of the intermediate element 4 is - according to FIG. 1 - Further, a shearing device 21 (in the Figures 2 and 3 not shown), which serves for shearing a sprue. This is the solidified medium in the casting run 16. Hereinafter will be discussed in more detail.

Die Figuren 4 und 5 zeigen die Abschervorrichtung 21, die einen Schieber 22 aufweist, der linear hin- und herbewegt wird, wobei seine Bewegungsrichtung parallel zu den Trennebenen - und somit senkrecht zur Verfahrrichtung der Formteile - zwischen den Formteilen 5 bis 8 und Zwischenelementteilen 9 und 10 verläuft. Am Schieber 22 befindet sich ein Abschermesser 23. Wird der Schieber 22 aus der Abschervorrichtung 21 herausbewegt, so trifft er auf einen Anguss 24. Dieser besteht aus einem voll oder teilweise erstarrten Medium und ist durch Auseinanderfahren der Zwischenelementteile 9 und 10 frei zugänglich. Durch die erfolgende Bewegung des Abschermessers 23 wird der Anguss 24 abgetrennt, sodass er - gemäß Figur 5 - nach unten fällt (Pfeil 25). Anschließend kann das Abschermesser 23 (gemäß Figur 5) wieder eingefahren werden.The FIGS. 4 and 5 show the shearing device 21, which has a slider 22 which is reciprocated linearly, with its direction of movement parallel to the parting planes - and thus perpendicular to the direction of movement of the molded parts - between the mold parts 5 to 8 and intermediate element parts 9 and 10 extends. The slide 22 is moved out of the shearing device 21, it meets a sprue 24. This consists of a fully or partially solidified medium and is freely accessible by moving apart of the intermediate element parts 9 and 10. By the successful movement of the Abschermessers 23, the gate 24 is separated so that he - according to FIG. 5 - falls down (arrow 25). Subsequently, the shearing blade 23 (according to FIG FIG. 5 ) are retracted again.

Die Figuren 6 bis 8 verdeutlichen die Darstellungen der Figuren 1 bis 3. Nach dem Abscheren des Angusses 24 erfolgt ein Entformen der Werkstücke 18. Hierzu sind an den Zwischenelementteilen 9 und 10 Auswerferplatten 26 und 27 vorgesehen, die zu den Auswerfervorrichtungen 19 und 20 gehören. Die Auswerfervorrichtungen 19 und 20 weisen Auswerferzylinder 28 und 29 auf, die seitlich oder nach oben zu den Formteilen 6 und 7 angeordnet und als Blockzylinder ausgebildet sind. Sie ermöglichen das Aufbringen einer Auswurfkraft derart, dass die Werkstücke 18 - wie in Figur 7 ersichtlich - ausgeworfen werden. Die Figur 8 zeigt eine perspektivische Darstellung der Anordnung der Figur 7, jedoch um eine Hochachse um 180° gedreht und in perspektivischer Ansicht. Es ist erkennbar, dass die Formteile 5 bis 8 jeweils Formeinsätze 30 und 31 tragen, die auswechselbar sind, um unterschiedliche Werkstücke 18 herstellen zu können.The FIGS. 6 to 8 clarify the representations of the FIGS. 1 to 3 , After shearing off the sprue 24, the workpieces 18 are removed from the mold. For this purpose, ejector plates 26 and 27, which belong to the ejector devices 19 and 20, are provided on the intermediate element parts 9 and 10. The Auswerfervorrichtungen 19 and 20 have ejector cylinders 28 and 29 which are arranged laterally or upwardly to the mold parts 6 and 7 and formed as a block cylinder. They allow the application of an ejection force such that the workpieces 18 - as in FIG. 7 visible - ejected. The FIG. 8 shows a perspective view of the arrangement of FIG. 7 , but rotated about a vertical axis by 180 ° and in perspective view. It can be seen that the mold parts 5 to 8 each carry mold inserts 30 and 31, which are interchangeable to produce different workpieces 18 can.

Ein Vergleich der Figuren 6 und 7 zeigt, dass in der geschlossenen Stellung das Etagenpaket, das von der ersten Form 2, der zweiten Form 3 und dem Zwischenelement 4 gebildet ist, die Abstand d aufweist. In der vollständig geöffneten Stellung gemäß Figur 7 beträgt die Abstand 2d, ist also etwa doppelt so groß. Hieraus folgt, dass das erfindungsgemäße Druckgießwerkzeug 1 nur einen relativ kleinen Platzbedarf für seinen Betrieb benötigt und dennoch aufgrund der Etagenbauweise eine Vielzahl von Werkstücken 18 pro Zeiteinheit gefertigt werden können.A comparison of FIGS. 6 and 7 shows that in the closed position, the stack of floors, which is formed by the first mold 2, the second mold 3 and the intermediate element 4, the distance d. In the fully open position according to FIG. 7 is the distance 2d, so it is about twice as large. It follows that the diecasting tool 1 according to the invention requires only a relatively small space requirement for its operation and yet a plurality of workpieces 18 can be manufactured per unit time due to the stack construction.

Hat das Druckgusswerkzeug 1 einen Fertigungszyklus gemäß der Figuren 1 bis 3 durchlaufen, so werden die Formen 2 und 3 wieder geschlossen und es kann erneut ein Druckgussvorgang vorgenommen werden.Has the die-casting tool 1 a production cycle according to the FIGS. 1 to 3 go through, then the forms 2 and 3 again closed and it can be made a die-casting process again.
