Description

Die Erfindung betrifft ein Verfahren für die Herstellung und das Abgießen sowie Ausformen der Gießformen sowie eine Gießanlage für die Durchführung des Verfahrens.The invention relates to a method for the production and pouring and molding the molds as well as a casting plant for carrying out the process.

Die mit einem Formkasten versehenen Gießformen werden in bekannter Art und Weise in einer Formmaschine geformt, wobei diese Formmaschine vorteilhaft einen Drehtisch aufweist, der eine Modellplatte für sowohl die eine als auch die andere Formkastenhälfte besitzt. Der Rahmen wird auf die Modellplatte abgesetzt und mittels Sand gefüllt, wobei es sich hier in der Regel um einen tongebundenen Sand handelt. Nach dem entsprechenden Verdichten des Formsandes wird die Formkastenhälfte von der Modellplatte abgehoben und auf eine Transportbahn aufgesetzt. In diese Transportbahn ist eine Wendeeinrichtung eingebaut, die die Formkastenhälften derart wendet, daß die Formteilebene nach oben zeigt. Hierdurch ist zum einen die Kerneinlegung wesentlich erleichtert und zum anderen kann bei den herkömmlich ausgebildeten Gießformen der Eingießtrichter sowie der Speiser nachgearbeitet werden. Nachdem die Kerne eingelegt sind, wird die eine Formkastenhälfte in einem Wender gewendet und die Formkastenhälften werden dann in einer Einrichtung zum Zusammensetzen der beiden Formkastenhälften zusammengefügt. Im Anschluß hieran erfolgt der Abguß der Gießform in liegender Stellung. Nach dem Erstarren des Gußstückes wird dieses ausgeformt. Die Formkastenhälften werden dann wieder getrennt und erneut der Formmaschine zugeführt.The molds provided with a molding box are molded in a known manner in a molding machine, this molding machine advantageously having a turntable has a model plate for both the has one as well as the other half of the molding box. Of the Frame is placed on the model plate and by means of Filled with sand, which is usually one clay-bound sand. After the corresponding one The molding box half of lifted off the model plate and onto a transport track put on. In this transport track is a turning device built in, which the mold box halves like turns that the molding plane faces upwards. Hereby on the one hand, the core insertion is much easier and on the other hand, the conventionally trained Casting molds for the pouring funnel and the Feeders to be reworked. After the seeds are inserted are the one mold box half in a turner then turned and the mold box halves are in a facility for putting the two together Molded box halves joined together. Following this the casting mold is cast in a lying position. After the casting has solidified, it is shaped. The mold box halves are then separated again and fed again to the molding machine.

Das Abgießen der Formkästen in liegender Stellung bereitet insofern bei komplizierteren Gußstücken und vor allem wenn Gußstücke mit Aluminium hergestellt werden sollen, größere Probleme, da es nicht immer möglich ist, ein optimales Speiservolumen mit einem ausreichenden hydrostatischen Druck in der Gießform auszubilden. Man ist hier gezwungen, zusätzlich noch Speiser auf der Gießform aufzusetzen, was nicht unproblematisch ist und zudem einen zusätzlichen Arbeitsaufwand bedeutet.The casting of the mold boxes in a lying position prepares to that extent with more complicated castings and before especially if castings are made with aluminum are supposed to have bigger problems since it's not always possible is an optimal feeder volume with a sufficient to develop hydrostatic pressure in the mold. One is forced here, in addition, even feeders on the Put on the mold, which is not without problems and also means additional work.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine Gießanlage für die Durchführung des Verfahrens der eingangs genannten Art vorzuschlagen, wodurch es möglich wird, Gußstücke auch aus Aluminium herzustellen, die in der Gußqualität wesentlich verbessert sind und bei denen es auch bei komplizierten Gußstücken nicht erforderlich ist, zusätzliche Speiser vorzusehen. The invention has for its object a method as well as a casting plant for carrying out the process to propose of the type mentioned, whereby it becomes possible to make castings from aluminum, which significantly improved in casting quality are and where it is even with complicated castings it is not necessary to provide additional feeders.

Eine weitere Aufgabe der Erfindung besteht darin, die Gießanlage so auszugestalten, daß diese kostengünstig automatisch arbeiten kann.Another object of the invention is that To design the casting system so that it is inexpensive can work automatically.

Diese Aufgabe wird für das Verfahren mit den Merkmalen des Anspruches 1 und für die Gießanlage mit den Merkmalen des Anspruches 4 gelöst.This task is for the method with the characteristics of claim 1 and for the casting machine with the features of claim 4 solved.

Die grundlegende Idee des erfindungsgemäßen Gießverfahrens wie auch der Gießanlage bestehen darin, daß mit Formkästen versehene Gießformen verwendet werden, die in herkömmlicher Art und Weise liegend geformt und mit Kernen versehen, die jedoch so ausgebildet sind, daß der Eingießtrichter wie auch der Speiser in der Formteilebene der Gießform angeordnet ist. Hierdurch bedingt wird zwar die Formung der Gießform in liegender Weise durchgeführt, jedoch der Abguß in stehender Weise, wobei bei derartigen Anordnungen nicht nur ein ausreichendes Speiservolumen zu schaffen ist, sondern darüber hinaus auch ein ausreichender hydrostatischer Druck für das nachzuspeisende Metall erhalten wird. Hierdurch ist es möglich, auch komplizierte Aluminiumgußstücke, beispielsweise Motorblöcke oder Zylinderköpfe, kostengünstig herzustellen. Derartige Gußstücke werden bisher in chemisch gebundenen kastenlosen Gießformen hergestellt, welche nicht nur eine teure Sandaufarbeitung bedingen, sondern darüber hinaus auch teure und komplizierte Anlagen für die Herstellung der vielen Formteile für die kastenlose Gießform, die zudem noch teils mit Automaten und teils von Hand, zusammengesetzt werden müssen.The basic idea of the casting process according to the invention as well as the caster are that with Molds provided with mold boxes are used shaped in a conventional manner and with Cores provided, but which are designed so that the pouring funnel as well as the feeder in the molded part level the mold is arranged. Due to this the shape of the mold becomes horizontal Carried out way, however the cast in standing Way, with such arrangements not only one sufficient feed volume is to be created, but also a sufficient hydrostatic Pressure for the metal to be replenished is obtained. This enables even complex aluminum castings, for example engine blocks or cylinder heads, inexpensive to manufacture. Such castings have been used in chemically bound, castless molds manufactured, which is not just an expensive sand processing condition, but also beyond expensive and complicated equipment for the production of many molded parts for the castless mold, which also partly assembled with machines and partly by hand Need to become.

Eine erfindungsgemäße Gießanlage ist mit herkömmlichen Anlageeinheiten bis zum Zusammenfügen der beiden Gießformhälften aufgebaut, so daß hier auf bewährte und kostengünstige Anlagenkomponenten zurückgegriffen werden kann. Im Anschluß an das Zusammenfügen der beiden Formkästen ist in die Gießformanlage eine Wendeeinrichtung eingebaut die es gestattet, den Formkasten um seine Längsachse um 90 Grad zu wenden, so daß dieser nunmehr hochkant auf einer weiteren, in der Regel etwas schmäleren, Transportbahn weitergeführt wird. In dieser stehenden Stellung der Gießformen erfolgt der Abguß und gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung auch das Auspacken der Gießformen. Hierzu kann die Gießform auf der Transportbahn verbleiben. Sie muß lediglich senkrecht zur Gießform gesichert werden, so daß dann anschließend das Gußstück mittels einer Pressplatte aus dem Gießformrahmen zusammen mit dem gebundenen Formsand ausgedrückt werden kann. Die Formkästen werden kann um 90 Grad gedreht und in liegender Stellung getrennt und in bekannter Art und Weise wieder so vorbereitet, daß sie erneut der Formanlage zugeführt werden können.A casting plant according to the invention is conventional System units until the two mold halves are joined built so that here on proven and inexpensive Plant components can be used can. Following the joining of the two molded boxes is a turning device in the casting mold system built-in which allows the molding box to fit around its Longitudinal axis to turn 90 degrees, so that it is now upright on another, usually a little narrower, Transport track is continued. In this standing The casting molds are cast and according to a further advantageous embodiment of the Invention also unpacking the molds. For this the mold can remain on the conveyor track. she only needs to be secured perpendicular to the mold, so that then the casting by means of a Press plate from the mold frame together with the bound Molding sand can be expressed. The molded boxes can be rotated 90 degrees and lying down Position separated and in a known manner again prepared so that it is fed to the molding machine again can be.

Ein Ausführungsbeispiel der Erfindung ist im folgenden anhand der Zeichnung näher beschrieben, die eine erfindungsgemäß ausgebildete automatische Formanlage in perspektivischer Ansicht zeigt.An embodiment of the invention is as follows described in more detail with reference to the drawing, the one according to the invention trained automatic molding machine in perspective View shows.

Die in der Zeichnung dargestellte automatische Gießanlage (1) weist eine erste Transportbahn (2) auf, auf der die angelieferten Formkästen einer Trenneinrichtung (3) zugeführt werden, in der die Formkästen in je zwei einzelne Formkastenhälften (4,5) vereinzelt werden. In einer in eine zweite Transportbahn (6) eingeschaltete erste Wendeeinrichtung (7) werden die Formkastenhälften so gewendet, daß ihre Formteilungsebene nach unten zeigt. Die Formkastenhälften (4,5) werden dann einer Formanlage (8) zugeführt, die einen Drehtisch (9) aufweist, der Modellplatten (10,11) für die beiden Gießformhälften trägt. Die Formkastenhälften (4,5) werden über je eine der Modellplatten (10,11) abgesetzt, mit Sand verfüllt, verfestigt, um dann auf einer dritten Transportbahn (12) abgesetzt zu werden. In dieser Transportbahn ist eine zweite Wendeeinrichtung (13) eingeschaltet, die die Formkastenhälften (4,5) um 180 Grad wendet, so daß die Formteilebene und damit der Formhohlraum (14) der Formkästen (4,5) nach oben zeigt. Die dritte Transportbahn (12) weist dann eine Kerneinlegestrecke (15) auf, in der die Kerne in die nach oben zeigenden Formhohlräume in einfacher Art und Weise einlegbar sind. In einer dritten Wendeeinrichtung (16) wird dann eine Formkastenhälfte um 180 Grad gewendet, wobei dann die Formkastenhälften (4,5) einer Zusammensetzstation (17) zugeführt werden, in der eine Formkastenhälfte auf die zugehörige andere Formkastenhälfte aufgesetzt und zu einer Gießform zusammengefügt wird.The automatic casting machine shown in the drawing (1) has a first transport path (2) the delivered mold boxes of a separating device (3) are fed in the mold boxes in two individual mold box halves (4,5) can be separated. In one switched into a second transport track (6) The first turning device (7) becomes the mold box halves turned so that their parting plane down shows. The mold box halves (4,5) then become one Forming system (8) fed, which has a rotary table (9), the model plates (10, 11) for the two mold halves wearing. The mold box halves (4,5) deposited over each of the model plates (10, 11), with Sand filled, solidified, then on a third Transport track (12) to be dropped. In this Transport track is a second turning device (13) turned on, the mold box halves (4,5) by 180 Degree turns so that the molding level and thus the Mold cavity (14) of the mold boxes (4,5) shows upwards. The third transport path (12) then has a core insertion path (15) in which the cores are in the upward direction showing mold cavities can be inserted in a simple manner are. In a third turning device (16) a mold box half is then turned through 180 degrees, then the mold box halves (4, 5) of an assembly station (17) are fed in a mold box half on the corresponding other mold box half put on and assembled into a mold.

Im Anschluß hieran werden die fertigen Gießformen (18) über ein viertes Transportband (19) einer vierten Wendeeinrichtung (20) zugeführt, die die Formkästen um ihre Längsachse um 90 Grad wendet und auf einer fünften Transportbahn (21) absetzt, welche die nunmehr hochkant stehenden Gießformen (18) aufnimmt.Following this, the finished molds (18) via a fourth conveyor belt (19) of a fourth turning device (20) fed around the mold boxes their longitudinal axis turns 90 degrees and on a fifth Transport track (21) settles, which is now upright standing molds (18).

Die Gießformen sind so hergestellt, daß der Eingießtrichter (22) und der Speiser (23) in der Teilungsebene (24) der Gießform (18) liegen. Der Abguß der Gießformen (18) erfolgt in einer Gießstation (30) auf einer fünften Transportbahn (21), wobei diese auch gleichzeitig die Abkühlstrecke bildet. Nach dem Erstarren des Gußstückes gelangt die Gießform (18) in eine Ausformstation (25), welche eine von einem Hubzylinder (27) angetriebene Pressplatte (26) aufweist. Des weiteren fixiert die Ausformstation (25) die Gießform (18) senkrecht zu ihrer Transportrichtung, so daß die Entformung ohne Abnahme der Gießform von der fünften Transportbahn (21) durchgeführt werden kann. Auf der der Pressplatte (26) gegenüberliegenden Seite der Gießform ist ein Aufnahmetisch (28) vorgesehen, auf den das Gußstück aufgeschoben wird. Der Ausformstation (25) ist eine fünfte Wendeeinrichtung (29) nachgeschaltet, die den Formkasten wiederum um 90 Grad um seine Längsachse dreht, so daR nunmehr der Weitertransport und die Trennung der beiden Formkastenhälften (4,5) in der Trennstation in üblicher Art und Weise erfolgen kann. Der Vorgang wiederholt sich dann wie zuvor beschrieben.The molds are made so that the pouring funnel (22) and the feeder (23) in the division level (24) of the mold (18). The casting of the molds (18) takes place in a casting station (30) on a fifth Transport track (21), this also at the same time forms the cooling section. After the casting has solidified the mold (18) arrives in a molding station (25), which is driven by a lifting cylinder (27) Press plate (26). Furthermore fixed the molding station (25) the casting mold (18) vertically to their direction of transport, so that the demolding without removing the mold from the fifth conveyor track (21) can be carried out. On the press plate (26) opposite side of the mold is a shooting table (28) provided on which the casting is pushed becomes. The shaping station (25) is a fifth Turning device (29) connected downstream of the molding box again rotates 90 degrees around its longitudinal axis, so that now the further transport and the separation of the two mold box halves (4,5) in the separation station in usual way can be done. The process repeats then as described previously.

Der wesentliche Vorteil der erfindungsgemäßen Formanlage besteht darin, daß durch die stehende Anordnung der Gießformen beim Abguß ein ausreichendes Speiservolumen mit einem ausreichenden hydrostatischen Druck auch für schwer vergießbare Metalle, beispielsweise Aluminium, erhalten werden kann, so daß es nunmehr möglich ist, auch komplizierte Gußstücke wie Motorblöcke oder Zylinderköpfe aus Aluminium mit kastengebundenen Gießformen herzustellen. Durch diesen Abguß mit stehenden Gießformen ist gleichfalls der Ausformgang wesentlich vereinfacht, da nunmehr die Gießform nicht mehr von den Transportband abgenommen zu werden braucht, sondern lediglich das Gußstück seitlich ausgeschoben wird, wobei dieses dann frei handhabbar ist. The main advantage of the molding system according to the invention is that by the standing arrangement the casting molds have a sufficient feed volume during casting with sufficient hydrostatic pressure also for difficult to cast metals, for example Aluminum, can be obtained so that it is now possible is complex castings such as engine blocks or cylinder heads made of aluminum with box-bound To produce casting molds. Through this cast with standing The molding process is also essential for casting molds simplified since the mold is no longer needs to be removed from the conveyor belt but only pushed out the casting laterally is, which is then free to use.
