Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur lösbaren Befestigung eines Formrahmens nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for releasably fastening a mold frame according to the preamble of
Eine bekannte Vorrichtung der genannten Art nach der DE-A - 33 14 272 weist zwischen dem Formtisch und den Schenkeln des U-förmigen Formrahmens jeweils ein mit Führungsnuten versehenes Führungsorgan auf, auf welchem der Formrahmen mittels einer seitlichen Führungsleiste aufliegt und das in der Betriebslage den Formrahmen durch den unter sich eingeschobenen Keil gegen die oberen Anstellflächen der Führungsnuten hält, derart, dass seitlich über die Formenoberfläche hinaus eine aus mehreren Teilen gebildete, weitgehend plane Fläche entsteht.A known device of the type mentioned in DE-A - 33 14 272 has between the molding table and the legs of the U-shaped molding frame, each with a guide element provided with guide grooves, on which the molding frame rests by means of a lateral guide bar and that in the operating position Holds the mold frame by the wedge inserted under it against the upper contact surfaces of the guide grooves, in such a way that a largely flat surface is formed laterally beyond the mold surface.
Diese Bauart verursacht aufgrund mehrerer Bauteile und/oder zusätzlicher Führungsorgane spürbare hohe Konstruktions- und Fertigungskosten. Der bei der bekannten Bauart entstehende Verschleiss kann nur mit hohem Aufwand korrigiert werden.This design causes noticeably high design and manufacturing costs due to several components and / or additional guide elements. The wear that occurs with the known design can only be corrected with great effort.
Aufgabe der Erfindung ist es somit, eine Vorrichtung nach der eingangs erwähnten Art zu schaffen, die sich durch Einfachheit auszeichnet und eine grosse Dimensionierungsfreiheit bzw. einen hohen Grad der universellen Verwendbarkeit zulässt.The object of the invention is therefore to provide a device of the type mentioned at the outset, which is characterized by simplicity and allows great freedom of dimensioning or a high degree of universal usability.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die der Formeinfüllöffnung zugeordnete Oberfläche des Formrahmens und die an dem Formtisch vorgesehenen Anstellflächen eine gemeinsame Ebene bilden.According to the invention, this object is achieved in that the surface of the mold frame assigned to the mold filling opening and the contact surfaces provided on the mold table form a common plane.
Dieses Bauprinzip ermöglicht eine gegenüber den bisherigen Ausführungsformen vereinfachte Anordnungsweise von Formtisch und Formrahmen innerhalb einer Presse und gestattet die Verwendung verschiedener Hebe- und Spannmittel, beispielsweise hydraulische, pneumatische oder mechanische Hebezeuge, Keile, Spindelantriebe etc., zur Verankerung des Formrahmens im Formtisch.This construction principle enables a simplified arrangement of the molding table and molding frame within a press compared to the previous embodiments and allows the use of various lifting and clamping devices, for example hydraulic, pneumatic or mechanical lifting devices, wedges, spindle drives etc., for anchoring the molding frame in the molding table.
Insbesondere an einer Steinpresse zur Herstellung von Formkörpern aus einem schüttfähigen Material (keramische Formmasse), welches mittels eines Formfüllschiebers dem in dem Formrahmen vorgesehenen Formhohlraum zugeführt wird, erweist sich das erfindungsgemässe Konstruktionsprinzip als vorteilhaft, indem die an den Formrahmen angrenzende Auflagefläche des Füllschiebers an die aus Formtisch und Formrahmen gebildete gemeinsame Ebene bündig übergehen kann. Die Ausgestaltung und Anordnungsweise dieser Grossteile kann dadurch erheblich vereinfacht werden und die Nacharbeit bei Formverschleiss reduziert werden.In particular on a stone press for the production of moldings from a pourable material (ceramic molding compound), which is fed to the mold cavity provided in the mold frame by means of a mold fill slide, the construction principle according to the invention proves to be advantageous in that the contact surface of the fill slide adjoining the mold frame turns out against it Form table and mold frame formed joint level can pass flush. The design and arrangement of these large parts can thereby be considerably simplified and the rework in the case of mold wear can be reduced.
Eine spezielle Ausführungsform nach dem prinzipiellen Bausystem an einer Presse mit einem U-förmigen Formtisch, an dessen Innenseiten der Schenkel gegenüberliegende, mit dem einschiebbaren Formrahmen eine Führungsanordnung bildende, den Formrahmen durch Formträger an Abstützflächen aufnehmende Führungsnuten vorgesehen sind, die zwischen ihrer einen Anstellfläche und dem Formträger jeweils einen zur Verankerung des Formrahmens eintreibbaren Keil aufweisen, zeichnet sich dadurch aus, dass die Führungsnuten in den Schenkeln des Formtisches angeordnet sind und dass die der Formeinfüllöffnung zugeordnete Oberfläche des Formrahmens und die anderen Anstellflächen der Führungsnuten in der Betriebslage des Formrahmens die gemeinsame Ebene bilden.A special embodiment according to the basic construction system on a press with a U-shaped molding table, on the inside of which the leg opposite, with the insertable mold frame forming a guide arrangement, the mold frame by means of mold carriers on support surfaces are provided with guide grooves between their one contact surface and the Mold carriers each have a wedge that can be driven in to anchor the mold frame, characterized in that the guide grooves are arranged in the legs of the mold table and that the surface of the mold frame assigned to the mold filling opening and the other contact surfaces of the guide grooves form the common plane in the operating position of the mold frame .
Dadurch werden erhebliche Vorteile in der Fertigungs- und Anwendungstechnik dieser unumgehbaren Grossteile sowie wirtschaftlicher Art erzielt. Es wird u.a. möglich sein, die in den Schenkeln des U-förmigen Formtisches vorgesehenen Führungsnuten durch Aussparungen beim Giessmodell zu berücksichtigen. Die spanabhebende Bearbeitung wird erheblich vereinfacht und kostengünstiger. Der Formrahmen wird ohne Minderung seiner Festigkeit vereinfacht und das Einführen erfolgt ohne besondere Umstände; es können dadurch Hindernisse am Formtisch abgebaut werden. Die Universalität kann durch die Vereinfachung des Formrahmens noch verbessert werden und die früher benutzten Formrahmen können durch geringe Anpassungen an die einheitliche Befestigungsform wiederverwendet werden. Die Nacharbeit an den Anstellflächen entfällt.This results in considerable advantages in the manufacturing and application technology of these inevitable large parts as well as being economical. Among other things, be possible to take into account the guide grooves provided in the legs of the U-shaped molding table through recesses in the casting model. Machining is considerably simplified and less expensive. The form frame is simplified without reducing its strength and the insertion takes place without special circumstances; obstacles on the forming table can thereby be removed. The universality can be further improved by simplifying the form frame and the form frames used previously can be reused by making minor adjustments to the uniform fastening form. Rework on the parking spaces is no longer necessary.
Die durch den Einsatz des Formrahmens, vornehmlich an dessen Oberfläche eintretenden Abnutzungserscheinungen durch das Bewegen des Füllschiebers, die von Zeit zu Zeit ein Ueberschleifen verlangen, wirken sich aufgrund der Minderung der Formrahmenhöhe in keiner Weise negativ auf die Konstruktionsverhältnisse bzw. Genauigkeit und Anpassung des Formrahmens auf die ursprünglichen Einbauverhältnisse aus. Die Oberseite eines in seiner Höhe nachbearbeiteten Formrahmens nimmt im Betriebszustand immer wieder die gleiche Position ein.The wear and tear caused by the use of the mold frame, primarily on its surface due to the movement of the filler slide, which requires grinding from time to time, in no way have a negative effect on the design conditions or the accuracy and adaptation of the mold frame due to the reduction in the mold frame height the original installation conditions. The top of a mold frame reworked in its height always occupies the same position in the operating state.
Es erweist sich dann als besonders zweckmässig, wenn die Abstützflächen des Formrahmens mit dessen Oberfläche eine Schulter bilden, die bei der Befestigung jeweils zwischen eine Anstellfläche einer Führungsnut und einen Formträger eingespannt wird.It proves to be particularly expedient if the support surfaces of the mold frame form a shoulder with its surface, which is clamped between a contact surface of a guide groove and a mold carrier during the fastening.
Zur Meidung von Verschleissmarken oder Abnützungserscheinungen an dem Formtisch ist jeweils die die Keilbahn bildende eine Anstellfläche der Führungsnuten mit einer Leiste ausgebildet, für deren Anordnung eine stufenartige Ausnahme im Formtisch entlang der Führungsnuten vorgesehen ist und die mittels Schrauben an dem Formtisch befestigt sind.In order to avoid wear marks or signs of wear on the forming table, the contact groove forming the keyway is in each case a contact surface of the guide grooves Formed bar, for the arrangement of which a step-like exception is provided in the molding table along the guide grooves and which are fastened to the molding table by means of screws.
Zum gleichen Zweck ist an der der Schulter des Formrahmens zugekehrten Auflagefläche der Formträger eine Platte auswechselbar befestigt.For the same purpose, a plate is exchangeably attached to the support surface of the mold carrier facing the shoulder of the mold frame.
