Description

Die Erfindung betrifft eine kastenlose, horizontal geteilte Gießform, mit wenigstens zwei aus einer Formmasse gebildeten Formballen die einen Gießhohlraum begrenzen, gemäß Anspruch 1.
Zur Herstellung von Gussstücken benötigt man eine Form, die mit flüssigem Gießmetall gefüllt wird und in der das Gussstück erstarren kann. Der Hohlraum der Form ist das negative Abbild des Gussstückes.The invention relates to a boxless, horizontally divided casting mold, with at least two molded bales formed from a molding compound which delimit a casting cavity, according to claim 1.
For the production of castings, you need a mold that is filled with liquid casting metal and in which the casting can solidify. The cavity of the mold is the negative image of the casting.

Die Zuführung des flüssigen Metalls in den Hohlraum der Gießform erfolgt über eine Zuleitung. Dabei unterscheidet man prinzipiell zwei Varianten der Zuführung des Gießmaterials: Bei der ersten Variante erfolgt das Abgießen der Gießform im steigenden Guss, wobei das Gießmaterial über einen Trichter und einen Eingießkanal in die auszugießende Form gelangt. Bei der zweiten Variante wird aus einem unterhalb der Gießform befindlichem Schmelztiegel das Gießmaterial in die Gießform über ein Steigrohr eingedrückt.The supply of liquid metal into the cavity of the mold via a supply line. In principle, two variants of the feeding of the casting material are distinguished: In the first variant, the casting mold is cast in the rising mold, with the casting material passing through a funnel and a pouring channel into the mold to be poured out. In the second variant, the casting material is pressed into the casting mold via a riser from a crucible located below the casting mold.

Bei der Herstellung von Gussstücken können entweder verlorene Formen öder Dauerformen verwendet werden. Verlorene Formen werden bei der Entnahme des Gussstücks zerstört. Diese Formen werden aus einer Formmasse gebildet. Sie bestehen meist aus Quarzsand in Kombination mit einem Bindemittel. Dauerformen werden häufig verwendet, wenn Gussstücke aus Nichteisenmetallen in größer Stückzahl hergestellt werden müssen. Diese Formen bestehen aus Stahl- oder Eisen-Gusswerkstoffen oder Nicht-Eisenwerkstoffe.In the production of castings, either lost molds or permanent molds can be used. Lost shapes are destroyed when the casting is removed. These forms are formed from a molding compound. They usually consist of quartz sand in combination with a binder. Permanent molds are commonly used when casting non-ferrous metals into larger ones Quantity must be produced. These molds are made of steel or cast iron or non-ferrous materials.

Die Erfindung betrifft eine verlorene Gießform.The invention relates to a lost mold.

Verlorene Gießformen können kastenlos sein oder aber einen Formkasten aufweisen, der aus zwei Formkastenhälften besteht, wie er beispielsweise in der DE 530 510 C , der DE 24 15 115 A1 und vielen anderen dargestellt ist. Bei der Erfindung handelt es sich um eine kastenlose Gießform.Lost casting molds can be boxless or have a molding box, which consists of two mold box halves, as for example in the DE 530 510 C , of the DE 24 15 115 A1 and many others. The invention is a boxless casting mold.

Bei kastenlosen Gießformen handelt es sich um meist zweiteilige Formen. Sie werden ohne Ober- und Unterkästen verwendet. Lediglich für die Herstellung der Formballen sowie zur genauen Zentrierung vom oberen und unteren Formballen werden Formrahmen verwendet, die anschließend vor dern Abguss jedoch wieder entfernt werden. Für den Abguss erhält man dann einen sol genannten Formblock, der den wesentlichen Vorteil hat, dass die sehr hohen Investitionskosten für den Formkastenpark entfallen. Die DE 35 39 042 A1 zeigt eine derartige Anordnung.Castless casting molds are usually two-part molds. They are used without top and bottom boxes. Forming frames are used only for the production of the shaped bales and for the exact centering of the upper and lower mold bales, which are subsequently removed again before casting. For the casting, one then obtains a so-called molding block, which has the significant advantage that the very high investment costs for the molding box park are eliminated. The DE 35 39 042 A1 shows such an arrangement.

Kastenlose Gießformen werden in der Gießerei in zunehmendem Maße eingesetzt. Die Gießformen sind zumeist quader- oder würfelförmig ausgebildet und weisen eine Formfläche oder zwei einander gegenüberliegende Formflächen auf, in der bzw. in denen die Modelle abgeformt sind. Zwei Gießformen ergeben zusammen eine Form des zu gießenden Gussstückes. Die geschlossenen kastenlösen Gießformen werden für den Abguss nebeneinander auf eine Gießstrecke gesetzt. In den Formballen ist gleichzeitig ein Eingusstrichter und ein Eingießkanal mit eingeformt, so dass nach dem Zusammenfügen der Formballen zu den Gießformen unmittelbar mit dem Abguss begonnen werden kann. Der Vorteil dieser kastenlosen Gießformen besteht darin, dass ein aus einem Unter- und Oberkasten bestehender Formkasten nicht erforderlich ist.Castless casting molds are increasingly being used in the foundry. The casting molds are generally cuboid or cube-shaped and have a molding surface or two opposing mold surfaces in which or in which the models are molded. Two molds together form a shape of the casting to be cast. The closed box-casting molds are placed side by side on a casting line for the casting. At the same time, a pouring funnel and a pouring channel are formed in the shaped bales, so that casting can be started directly after the bales have been joined to form the casting molds. The advantage of this caseless casting molds is that a molding box consisting of a lower and upper box is not required.

Vor dem Abguss müssen die Formballen zueinander ausgerichtet und dauerhaft fixiert werden. Diese Ausrichtung ist sehr zeitaufwendig.Before casting, the bales must be aligned with each other and permanently fixed. This alignment is very time consuming.

Aufgabe der vorliegenden Erfindung ist es, eine kastenlose Gießform zu schaffen, bei der die Ausrichtung der Formballen zueinander schnell und präzise vorgenommen werden kann.The object of the present invention is to provide a boxless casting mold, in which the orientation of the molded bale to each other can be made quickly and accurately.

Diese Aufgabe wird erfingdungsgemäß dadurch gelöst, dass zwei einander gegenüberliegende Formballen Öffnungen aufweisen und die Öffnungen zur horizontalen Ausrichtung der Formballen eine vertikale Führungslinie für ein stabartiges Führungselement bilden.According to the invention, this object is achieved in that two opposing mold bales have openings and the openings for horizontal alignment of the mold bales form a vertical guide line for a rod-like guide element.

Bei den Öffnungen handelt es sich vorzugsweise um Kanäle, die in den Formballen verlaufen. Die Kanäle können unterschiedliche Querschnitte haben, wobei sich runde Querschnitte als besonders günstig erweisen.The openings are preferably channels that run in the moldballs. The channels may have different cross sections, with round cross sections prove to be particularly favorable.

Die Öffnungen sind in Bereichen der Formballen integriert an denen sie keine Verbindung zum Gießhohlraum haben. Vorzugsweise weisen dazu die Formballen Vorsprünge auf in denen die Öffnungen eingebracht sind. Bei diesen Vorsprüngen handelt es sich um gezielte Materialanhäufungen an Formmasse. In den Materialanhäufungen können durchgehende Öffnungen eingebracht werden ohne dass es zu einer Verletzung des Gießhohlraums kommt. Die Vorsprünge werden durch eine Materialanhäufung an Formmasse an den Seitenflächen der Formballen gebildet. Bei geschlossener Gießform wird in einigen Ausführungsformen der Erfindung zwischen den Vorsprüngen eine Aussparung gebildet. Das stabförmige Führungselement durchquert die Aussparung. Innerhalb der Aussparung ist das Führungselement nicht von einem Kanal umgeben. Die Führung wird ausschließlich von den Öffnungen im oberen und unteren Formballen bewerkstelligt.The openings are integrated in areas of the molded bales where they have no connection to the casting cavity. For this purpose, the shaped bales preferably have projections in which the openings are made. These projections are targeted material accumulations of molding material. In the material accumulations continuous openings can be introduced without causing injury to the casting cavity. The projections are formed by a material accumulation of molding material on the side surfaces of the mold bales. With the mold closed, a recess is formed between the protrusions in some embodiments of the invention. The rod-shaped guide member passes through the recess. Within the recess, the guide element is not surrounded by a channel. The guide is accomplished only by the openings in the upper and lower mold bales.

Zumindest in einem der beiden gegenüberliegenden Formballen ist ein durchgehender Kanal eingebracht. Der Kanal im Formballengegenstück kann auch nur in einen Teil des Formballens hineinragen. In einer bevorzugten Ausführung der Erfindung sind in beiden Formballen durchgehende Kanäle eingebracht.At least in one of the two opposing molded bales a continuous channel is introduced. The channel in the Formballengegenstück can also protrude only in a part of the mold. In a preferred embodiment of the invention, continuous channels are introduced in both mold bales.

Bei dem stabartigen Führungselement handelt es sich vorzugsweise um einen Metallstab mit einem runden Querschnitt. Der Durchmesser des Metallstabs wird dabei auf den Durchmesser der Öffnungen abgestimmt. Der Durchmesser des Metallstabs muss etwas geringer sein als der Durchmesser der Öffnungen: Als besonders günstig erweist es sich, wenn sich dadurch ein radiales Spiel von weniger als 1 mm, vorzugsweise weniger als 0,5 mm um den Stab ergibt. Dadurch ist es möglich, dass der Stab in die Öffnungen eingeführt und bewegt werden kann und dennoch eine ausreichend präzise Führung erreicht wird. Die Öffnungen bilden eine Führungslinie für das stabförmige Führungselement. Somit wird eine Linearführung des Führungselements erreicht.The rod-like guide element is preferably a metal rod with a round cross section. The diameter of the metal rod is matched to the diameter of the openings. The diameter of the metal rod must be slightly less than the diameter of the openings: It proves to be particularly favorable if this results in a radial clearance of less than 1 mm, preferably less than 0.5 mm around the rod. Thereby, it is possible that the rod can be inserted and moved into the openings and yet a sufficiently precise guidance is achieved. The openings form a guide line for the rod-shaped guide element. Thus, a linear guide of the guide element is achieved.

In einer besonders vorteilhaften Ausführung der Erfindung ist das stabartige Führungselement an seinem vorderen Ende in seinem Durchmesser reduziert. Vorzugsweise ist das vordere Ende des Stabes als kegelförmige Spitze ausgebildet. Dadurch wird die Einführung des Stabes in die Öffnungen erleichtert. Zudem erweist es sich als günstig, wenn zumindest eine Öffnung an der der gegenüberliegenden Formballen zugewandten Seite trichterförmig erweitert ausgebildet ist, um dem Stab den Eintritt in die Öffnung zu erleichtern.In a particularly advantageous embodiment of the invention, the rod-like guide element is reduced at its front end in its diameter. Preferably, the front end of the rod is formed as a conical tip. This facilitates the insertion of the rod into the openings. In addition, it proves to be advantageous if at least one opening is formed funnel-shaped widened on the side facing the opposite mold bale, in order to facilitate the rod entry into the opening.

Die Öffnungen bilden eine vertikale Führungslinie zur horizontalen Ausrichtung der Formballen. Ziel der horizontalen Ausrichtung ist es, die Formballen so aufeinander zu positionieren, dass die beiden Gießraumhälften korrekt zusammen gefügt werden und dadurch den vollständigen Gießhohlraum bilden, ohne dass es zu einer horizontalen Verschiebung der Hälften zueinander kommt. Der Gießhohlraum muss dazu das negative Abbild des zu gießenden Gussteil ergeben. Durch die erfindungsgemäße Vorrichtung wird verhindert, dass es zu einer seitlichen Verschiebung der Gießhohlraumhälften und somit zu einen Versatz des Gussteils kommt. Der Einsatz der Erfindung ermöglicht eine rasche horizontale Ausrichtung der Formballen zueinander.The openings form a vertical guide line for horizontal alignment of the molded bales. The aim of the horizontal alignment is to position the mold bales so that the two casting chamber halves are joined together correctly and thereby form the complete casting cavity, without any horizontal displacement of the halves to each other. The casting cavity must give the negative image of the casting to be cast. By means of the device according to the invention it is prevented that there is a lateral displacement of the casting cavity halves and thus an offset of the casting. The use of the invention allows rapid horizontal alignment of the mold balls to each other.

In einer besonders vorteilhaften Ausführung der Erfindung weist ein Formballen einen aus Formmasse gebildeten Wulst auf. Der Wulst bildet das positive Gegenstück zu einer Aushöhlung im gegenüberliegenden Formballen. Durch diese Ausführung wird eine Feinführung beim Zusammenfügen der Formballen erreicht. In diesem Fall dient die durch die Öffnungen gebildete Führungslinie einer Vorausrichtung, die bewirkt, dass sich der Wulst in die Aushöhlung einfügt. Bei herkömmlichen Gießformen besteht die Gefahr, dass der Wulst beim Zusammenfügen der Formballen gegenüber der Aushöhlung horizontal verschoben positioniert ist. Dadurch kann es zu einer Beschädigung des Wulstes kommen. Der aus Formmasse gebildete Wulst kann durch den Druck, der beim Zusammenfügen auf ihn ausgewirkt wird, zerstört werden.In a particularly advantageous embodiment of the invention, a molded bale has a bead formed from molding compound. The bead forms the positive counterpart to a hollow in the opposite ball of form. Through this design is achieved a fine guide when joining the bales. In this case, the guide line formed by the openings serves a pre-alignment which causes the bead to fit into the cavity. In conventional casting molds, there is a risk that the bead is positioned horizontally displaced with respect to the cavity during assembly of the molded bales. This can damage the bead. The bead formed from molding compound can be destroyed by the pressure applied to it during assembly.

Vorzugsweise handelt es sich bei dem Wulst um eine geometrische Form mit einer halbkugelförmigen Vorderseite und zylindrischen Seitenwänden. Die Halbkugelform erleichtert das Hineingleiten des Wulstes in den Hohlraum. Durch die zylindrischen Seitenwände wird eine Feinführung des Wulstes im Hohlraum erreicht. Der Hohlraum ist dabei als negatives Gegenstück zum Wulst ausgebildet.Preferably, the bead is a geometric shape having a hemispherical front and cylindrical sidewalls. The hemispherical shape facilitates the sliding of the bead into the cavity. Through the cylindrical side walls a fine guidance of the bead is achieved in the cavity. The cavity is designed as a negative counterpart to the bead.

Bei der Erfindung sind die Öffnungen so ausgebildet, dass sie eine Führungslinie für ein Verbindungselement bilden. Über das Verbindungselement sind die Formballen mittels zweier Gegenstücke verspannbar. Bei dem Verbindungselement handelt es sich vorzugsweise um einen Metallstab, der mit einem Gewinde versehen ist. Das Gewinde kann entweder entlang des gesamten Stabes verlaufen oder nur an den beiden Enden des Stabes aufgebracht sein. Die Verspannung der beiden Formballen zueinander erfolgt vorzugsweise mittels zweier Spannmuttern, die auf die beiden Endes des Stabes aufgeschraubt werden. Eine tellerförmige Fläche drückt auf das Formmaterial und presst die Ballen zusammen. Dabei kann entweder die Spannmutter mit einer tellerförmigen Fläche ausgebildet sein oder es können handelsübliche Muttern mit einer tellerförmigen Unterlegscheibe zum Einsatz kommen.In the invention, the openings are formed so that they form a guide line for a connecting element. About the connecting element, the molded bales are clamped by means of two counterparts. The connecting element is preferably a metal rod which is provided with a thread. The thread can either run along the entire bar or be applied only at the two ends of the rod. The clamping of the two mold balls to each other preferably takes place by means of two clamping nuts which are screwed onto the two ends of the rod. A plate-shaped surface presses on the molding material and presses the bales together. In this case, either the clamping nut may be formed with a plate-shaped surface or it can be commercially available nuts with a plate-shaped washer are used.

Ein Gegenstück ist in einem der Formballen integriert. Dazu kann eine Spannmutter in einen Formballen eingefüllt werden. Die tellerförmige Fläche der Spannmutter ist dabei von Formmasse eingeschlossen. Das Verbindungselement wird an einem Ende in die Spannmutter eingeschraubt und ragt mit seinem anderen Ende aus dem gegenüberliegenden Formballen heraus. Auf das herausragende Ende wird eine zweite Spannmutter aufgeschraubt. Durch Anziehen der Spannmuttern werden die Formballen gegeneinander verspannt.A counterpart is integrated in one of the molded bales. For this purpose, a clamping nut can be filled into a molded bale. The plate-shaped surface of the clamping nut is enclosed by molding material. The connecting element is screwed at one end into the clamping nut and protrudes with its other end from the opposite Mold bales out. On the protruding end of a second nut is screwed. By tightening the clamping nuts, the bales are braced against each other.

Bei einem Verfahren zur Herstellung der erfindungsgemäßen Gießform wird Formmasse in Formkästen und/oder Formrahmen gefüllt, wobei es sich um starre, biegungs- und verdrehungsfreie Teile zur Aufnahme und zum Festhalten der darin verdichteten Formmasse handelt. Die ausgehärtete Formmasse wird in Form von endfesten Formballen zur Sandgussfertigung verwendet. Eine solche Sandform besteht aus mindestens zwei Formteilen. Bei horizontal geteilten Gießformen werden diese als Ober- und Unterballen bezeichnet.In a method for producing the casting mold according to the invention, molding material is filled into molding boxes and / or molding frames, which are rigid, bending and twist-free parts for receiving and retaining the molding compound compressed therein. The cured molding material is used in the form of endfesten molded bales for sand casting. Such a sand mold consists of at least two molded parts. In horizontally split molds these are referred to as upper and lower bales.

Zur Herstellung der erfindungsgemäßen Gießform werden bei dem Herstellungsverfahren an den Befestigungselementen Bolzen positioniert, die bei der Herstellung der Formballen die Öffnungen in die Formballen einbringen. Die Bolzen werden so angeordnet, dass sie die Öffnungen so platzieren, dass sie für zwei einander gegenüberliegende Formballen eine vertikale Führungslinie für ein stabartiges Führungselement zur horizontalen Ausrichtung der Formballen bilden.In order to produce the casting mold according to the invention, in the manufacturing process, bolts are positioned on the fastening elements, which introduce the openings into the mold bales during production of the molded bales. The bolts are arranged so that they place the openings so that they form a vertical guide line for a rod-like guide element for horizontal alignment of the mold bales for two opposite mold bales.

Die Bolzen können auf den Befestigungselementen aufgeschraubt werden.The bolts can be screwed onto the fasteners.

In Fig. 1 a sind Einzelteile der erfindungsgemäßen Gießform dargestellt. Die Gießform besteht aus einem unteren Formballen 1 und einem oberen Formballen 2. Im unteren Formballen 1 ist eine Öffnung 3 eingebracht. Der obere Formballen 2 enthält eine Öffnung 4. Bei korrekter Positionierung der Formballen 1, 2 zueinander bilden die Öffnungen 3, 4 eine Führungslinie für das Führungselement 5. Das Führungselement 5 ist an seinem vorderen Ende als kegelförmige Spitze 6 ausgebildet. Das Führungselement 5 hat im Ausführungsbeispiel einen runden Querschnitt. Der Durchmesser des Führungselements 5 ist auf den Durchmesser der Öffnungen 3, 4 abgestimmt. Die kegelförmige Spitze 6 erleichtert das Einführen des Führungselements 5 in die Öffnung 4 des oberen Formballens 2.In Fig. 1 a are items of the mold according to the invention shown. The mold consists of a lower mold bale 1 and an upper mold bale 2. In the lower mold bale 1, an opening 3 is introduced. The upper mold bale 2 contains an opening 4. With correct positioning of the mold bales 1, 2 to each other, the openings 3, 4 form a guide line for the guide element 5. The guide element 5 is formed at its front end as a conical tip 6. The guide element 5 has a round cross section in the exemplary embodiment. The diameter of the guide element 5 is matched to the diameter of the openings 3, 4. The conical tip 6 facilitates insertion of the guide element 5 into the opening 4 of the upper mold bale 2.

Im oberen Formballen 2 ist ein Gießtümpel 7 eingebracht. In den Gießtümpel 7 wird die flüssige Schmelze gefüllt. Über einen Eingießkanal 8 gelangt die Schmelze in einen Gießhohlraum 9, der vom unteren Formballen 1 und vom oberen Formballen 2 begrenzt wird. Der untere Formballen 1 weist an seiner dem oberen Formballen 2 zugewandten Seite einen Wulst 10 auf. Bei dem aus Formmasse gebildeten Wulst 10 handelt es sich um das positive Gegenstück zur Aushöhlung 11 im oberen Formballen 2.In the upper mold bale 2 a pouring basin 7 is introduced. In the pouring basin 7, the liquid melt is filled. Via a pouring channel 8, the melt passes into a casting cavity 9, which is bounded by the lower mold bale 1 and the upper mold bale 2. The lower mold bale 1 has a bead 10 on its side facing the upper mold bale 2. The bead 10 formed of molding compound is the positive counterpart to the cavity 11 in the upper mold bale 2.

Im unteren Formballen 1 ist weiterhin ein Gegenstück 12 für ein Verbindungselement 13 (in den Fig. 1 nicht dargestellt) integriert. Bei dem Gegenstück 12 handelt es sich im Ausführungsbeispiel um eine Spannmutter, die mit einer tellerförmigen Fläche im Formmaterial eingebettet ist. Die Öffnung 3 im unteren Formballen 1 erweitert sich zu der dem oberen Formballen 2 zugewandten Seite. Der untere Formballen 1 weist einen aus einer Materialanhäufung gebildeten Vorsprung 14 auf. Der obere Formballen 2 weist einen aus einer Materialanhäufung gebildeten Vorsprung 15 auf. In den Vorsprüngen 14, 15 befinden sich die Öffnungen 3, 4.In the lower mold bale 1 is still a counterpart 12 for a connecting element 13 (in the Fig. 1 not shown) integrated. The counterpart 12 in the exemplary embodiment is a clamping nut which is embedded in the mold material with a plate-shaped surface. The opening 3 in the lower mold bale 1 expands to the side facing the upper mold bale 2. The lower mold bale 1 has a projection 14 formed from a material accumulation. The upper mold bale 2 has a projection 15 formed from a material accumulation. In the projections 14, 15 are the openings 3, 4th

In Fig. 1b wurde das Führungselement 5 durch die Öffnung 4 des oberen Formballens 2 hindurch gesteckt und ragt in die Öffnung 3 des unteren Formballens 1. Der Durchmesser des Innengewindes des Gegenstückes 12 ist größer als der Außendurchmesser des Führungselements 5, so dass das Führungselement auch durch das Gegenstück 12 hindurch führbar und innerhalb der Öffnungen 3, 4 und innerhalb des Gegenstücks 12 frei bewegbar ist. In der in Fig. 1b dargestellten Position sind die Formballen 1, 2 horizontal zueinander ausgerichtet. Zum Schließen der Gießform müssen die Formballen 1, 2 nur noch in vertikaler Richtung zueinander verschoben werden. Beim Zusammenfügen der Formballen 1, 2 tritt ab einer bestimmten vertikalen Annäherung der Formballen 1, 2 der Wulst 10 in die Aushöhlung 11 ein. Der Wulst 10 ist an seiner dem oberem Formballen 2 zugewandten Seite als Halbkugel ausgebildet, wobei jede andere Form auch möglich ist, beispielsweise eine kegelige Form. Die Seitenwände von Wulst 10 und Aushöhlung 11 sind hier zylinderförmig ausgebildet und dienen als Feinführung beim Zusammenfügen der Formballen 1, 2.In Fig. 1b the guide element 5 was inserted through the opening 4 of the upper mold bale 2 and protrudes into the opening 3 of the lower mold bale 1. The diameter of the internal thread of the counterpart 12 is greater than the outer diameter of the guide element 5, so that the guide element by the counterpart 12th can be guided and within the openings 3, 4 and within the counterpart 12 is freely movable. In the in Fig. 1b shown position, the bales 1, 2 are aligned horizontally to each other. To close the mold, the bales 1, 2 must be moved only in the vertical direction to each other. When assembling the molded bales 1, 2 occurs from a certain vertical approach of the bales 1, 2 of the bead 10 into the cavity 11 a. The bead 10 is formed on its side facing the upper mold bale 2 as a hemisphere, wherein any other shape is also possible, for example a conical shape. The side walls of the bead 10 and cavity 11 are cylindrical in shape and serve as a fine guide during the assembly of the molded bales 1, 2.

In Fig. 1c ist die Gießform in geschlossener Stellung dargestellt. Der Wulst 10 fügt sich nahtlos in die Aushöhlung 11 ein. Von den Formballen 1, 2 wird der Gießhohlraum 9 begrenzt, der die Form des zu fertigenden Werkstücks aufweist. Bei geschlossener Gießform entsteht zwischen oberen und unteren Formballen 2, 1 oder zwischen den Vorsprüngen 14, 15 eine Aussparung 16. Innerhalb der Aussparung 16 ist das Führungselement 5 sichtbar.In Fig. 1c the mold is shown in the closed position. The bead 10 fits seamlessly into the cavity 11. Of the molded bales 1, 2 of the casting cavity 9 is limited, which has the shape of the workpiece to be manufactured. When the mold is closed, a recess 16 forms between the upper and lower mold bales 2, 1 or between the projections 14, 15. Within the recess 16, the guide element 5 is visible.

Fig. 2 zeigt eine Formballenvariante ohne Vorsprünge. Die Öffnungen 3, 4 sind hier direkt in Formballen 1, 2 angeordnet, die ohne Vorsprünge ausgebildet wurden. Auf die Darstellung von Gießtümpel, Eingießkanal und Gießhohlraum wurde hier aus Gründen einer besseren Übersichtlichkeit verzichtet. Bei der Gießform gemäß Fig. 2 verläuft in den Öffnungen 3, 4 ein Verbindungselement 13. Mittels zweier Gegenstücke 12, 16 sind die Formballen 1, 2 verspannbar.
