Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von sanitärkeramischen Erzeugnissen, insbesondere Waschbecken, Klosettbecken, Sitzwaschbecken, Ablagen od.dgl., mittels aus wasseraufnehmendem Material, vorzugsweise Gips, hergestellten Formen, die jeweils mindestens aus zwei eine senkrechte Trennung aufweisenden Formteilen bestehen, welche nebeneinander auf einer Gießbank abgestellt und paarweise dichtend zusammenhaltbar sind, und die mittels einer absperrbaren Gießleitung zum steigenden Befüllen mit einem Schlickerbehälter verbindbar sind.The invention relates to a device for the production of sanitary ceramic products, in particular wash basins, toilet bowls, seat wash basins, shelves or the like, by means of molds produced from water-absorbing material, preferably plaster, which each consist of at least two molded parts which have a vertical separation and which are adjacent to one another parked in a casting bench and can be sealed together in pairs, and which can be connected to a slip container for increasing filling by means of a lockable casting line.

Vorrichtungen der voranstehend beschriebenen Art sind bekannt. Sie umfassen eine unterhalb der Gießbank ortsfest verlegte Gießleitung, die über jeweils einen abnehmbaren Verbindungsschlauch mit jeder Form verbunden wird, so daß alle Formen gleichzeitig über ihren Verbindungsschlauch durch die gemeinsame Gießleitung mit Schlicker aus dem Schlickerbehälter steigend gefüllt werden können. Sobald sich in den Formen der Scherben mit der gewünschten Wandstärke gebildet hat, wird der überschüssige Schlicker durch die Verbindungsschläuche in die Gießleitung abgelassen. Dieser überschüssige Schlicker wird wiederum dem Schlickerbehälter zugeführt, um zu einem späteren Zeitpunkt verarbeitet zu werden.Devices of the type described above are known. They comprise a pouring line which is permanently installed beneath the casting bench and which is connected to each mold by means of a detachable connecting hose, so that all the molds can be filled with slip from the slip container at the same time through the joint pouring pipe with the slip. As soon as the shards with the desired wall thickness have formed, the excess slip becomes through the connecting hoses drained into the pouring line. This excess slip is in turn fed to the slip container in order to be processed at a later point in time.

Damit die Gießleitung und die jeweils zu einer aus zwei Formteilen bestehenden Form führenden Verbindungsschläuche ständig verwendet werden können, ist es erforderlich, zumindest diese Teile der Gießanlage regelmäßig von Schlickerresten zu säubern. Zu diesem Zweck ist parallel zur Gießleitung eine Spülleitung vorgesehen. Diese Spülleitung besitzt Anschlußstutzen für sämtliche Verbindungsschläuche. Nach Abziehen des überschüssigen Schlickers werden die Verbindungsschläuche mit ihren oben liegenden Enden von den Formen abgenommen und auf die Stutzen der Spülleitung gesteckt. Auf diese Weise können alle Verbindungsschläuche und die Gießleitung durch aus dem Wassernetz entnommenes Wasser gespült werden. Dieses mit Schlickerresten verunreinigte Wasser wird einem Sumpf zugeführt. Vor jedem Gießvorgang müssen die Verbindungsschläuche sodann von der Spülleitung abgenommen und wieder an den Formen angebracht werden.So that the pouring line and the connecting hoses, each leading to a mold consisting of two molded parts, can be used continuously, it is necessary to regularly clean at least these parts of the pouring system from slip residues. For this purpose, a flushing line is provided parallel to the pouring line. This flushing line has connecting pieces for all connecting hoses. After removing the excess slip, the connection hoses with their ends lying above are removed from the molds and plugged onto the nozzles of the flushing line. In this way, all the connecting hoses and the pouring line can be rinsed by water removed from the water network. This water contaminated with slip residues is fed to a sump. Before each pouring process, the connecting hoses must then be removed from the flushing line and reattached to the molds.

Diese bekannte Art einer Gießvorrichtung erfordert nicht nur einen erheblichen Arbeitsaufwand für das Umstecken der Verbindungsschläuche, sondern hat durch das ständige Spülen der Verbindungsschläuche-und der Gießleitung einen Schlickerverlust zur Folge. Dieser Verlust entzieht jedoch nicht nur viele Tonnen Material dem eigentlichen Verwendungszweck, sondern verschmutzt große Wassermengen, die nur über eine Kläranlage abgeführt werden können und somit eine erhebliche Umweltbelastung darstellen.This known type of pouring device not only requires a considerable amount of work to reposition the connecting hoses, but also results in a loss of slip due to the constant flushing of the connecting hoses and the pouring line. However, this loss not only deprives many tonnes of material of its intended use, it also pollutes large amounts of water that can only be discharged through a sewage treatment plant and thus represent a significant environmental burden.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Vorrichtung dahingehend weiter zu entwickeln, daß bei geringerem Arbeits- und Anlagenaufwand Materialverluste und Umweltbelastungen vermieden werden.The invention has for its object the known To further develop the device in such a way that material losses and environmental pollution are avoided with less work and equipment.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß jedes Formteil unterhalb seines Hohlraums eine etwa waagerecht verlaufende und zwischen den senkrechten Stirnflächen des Formteils durchgehend ausgebildete Öffnung aufweist, die über mindestens einen Verbindungskanal mit dem Hohlraum der Form verbunden ist und die bei zusammengeschobenen Formen sowohl mit der Öffnung im zur jeweiligen Form gehörenden anderen Formteil als auch mit der Öffnung im anschließenden Formteil der benachbarten Form abgedichtet als Gießleitung verbunden ist.The solution to this problem by the invention is characterized in that each molded part below its cavity has an approximately horizontal opening which is formed continuously between the vertical end faces of the molded part and is connected to the cavity of the mold via at least one connecting channel and which in the case of collapsed molds is connected to the opening in the other mold part belonging to the respective mold as well as to the opening in the adjacent mold part of the adjacent mold in a sealed manner as a casting line.

Mit diesem Vorschlag der Erfindung wird die bei der bekannten Ausführung unterhalb der Gießbank angeordnete Gießleitung durch die in jedem Formteil ausgebildete Öffnung ersetzt. Hierdurch entfällt bei der erfindungsgemäßen Vorrichtung nicht nur die eigentliche Gießleitung, sondern auch sämtliche Verbindungsschläuche, da diese durch mindestens einen Verbindungskanal je Form ersetzt sind. Da jeweils zwei Formteile den zur Erzeugung des sanitärkeramischen Erzeugnisses dienenden Hohlraum bilden, genügt ein Verbindungskanal je Form, um den aus dem Schlickerbehälter durch Schwerkraft in die miteinander verbundenen Öffnungen eintretenden Schlicker von unten her in die Hohlräume der Formen einströmen zu lassen. Auch das Abziehen des überschüssigen Schlickers nach Bildung der Scherben geschieht über die Verbindungskanäle und die zu einer Gießleitung miteinander verbundenen Öffnungen, so daß insoweit keine Änderungen des Verfahrens gegenüber dem bekannten Stand der Technik eintreten.With this proposal of the invention, the casting line arranged below the casting bench in the known embodiment is replaced by the opening formed in each molded part. As a result, not only the actual pouring line is omitted in the device according to the invention, but also all connecting hoses, since these are replaced by at least one connecting channel per shape. Since two molded parts each form the cavity used to produce the sanitary ceramic product, one connecting channel per mold is sufficient to allow the slip, which enters the interconnected openings by gravity, from below into the cavities of the molds. The removal of the excess slip after the formation of the cullet occurs via the connecting channels and the openings connected to each other to form a pouring line, so that there are no changes in the process compared to this known prior art occur.

Ein weiterer wesentlicher Vorteil der erfindungsgemäßen Ausbildung besteht darin, daß ein Spülvorgang überflüssig wird. Der in den Öffnungen der Formteile und in den Verbindungskanälen verbleibende Schlicker verfestigt sich wegen des wasseraufnehmenden Materials der Formteile ebenso wie der Scherben. Nach dem Öffnen der Formen und dem Herausnehmen der Scherben können diese Schlickerreste somit auf einfache Weise den Formteilen entnommen werden. Da die verfestigten Schlickerreste innerhalb der Formteile keiner Verschmutzung ausgesetzt sind, können sie ohne Schwierigkeiten wieder aufbereitet und einem neuen Verarbeitungsprozeß zugeführt werden. Auf diese Weise wird nicht nur ein Verlust des teueren Materials vermieden, sondern auch die Notwendigkeit eines Spülvorganges, der einerseits eine erhebliche Wassermenge verbraucht und andererseits die Umwelt belastet.Another essential advantage of the design according to the invention is that a rinsing process is unnecessary. The slip remaining in the openings of the molded parts and in the connecting channels solidifies due to the water-absorbing material of the molded parts as well as the fragments. After opening the molds and removing the fragments, these slip residues can thus be removed from the molded parts in a simple manner. Since the solidified slip residues within the molded parts are not exposed to contamination, they can be reprocessed without difficulty and fed to a new processing process. In this way, not only is a loss of the expensive material avoided, but also the need for a rinsing process which on the one hand consumes a considerable amount of water and on the other hand pollutes the environment.

Gemäß einem weiteren Merkmal der Erfindung weist das jeweils vorderste Formteil der auf einer Gießbank befindlichen Formen einen aus der freien-Stirnfläche herausragenden Rohrstutzen zum Verbinden mit einem zum Schlickerbehälter führenden Gießleitungsstück auf. Auf diese Weise ist ein einfacher Anschluß der die Gießleitung beinhaltenden Formen an die zum Schlickerbehälter führende Leitung möglich.According to a further feature of the invention, the respective foremost mold part of the molds located on a casting bench a from the free - protruding end face pipe sockets for connecting to a Silt leading to the punch box Gießleitungsstück. In this way, a simple connection of the molds containing the casting line to the line leading to the slip container is possible.

Erfindungsgemäß weist jede aus mindestens zwei Formteilen bestehende Form mindestens einen Luftkanal auf, durch den während des Abführens des überschüssigen Schlickers Luft in den sich entleerenden Hohlraum der Form gepreßt wird, um das Entstehen eines Unterdruckes zu vermeiden. Anstelle jeweils einzelner Luftanschlüsse können gemäß einem weiteren Merkmal der Erfindung die Luftkanäle aller Formteile bei zusammengeschobenen Formen eine durchgehende Luftleitung bilden, so daß die Erfindung nicht nur die Gießleitung, sondern auch die Luftleitung durch entsprechend in den Formteilen ausgebildete Öffnungen ersetzt, die bei zusammengeschobenen Formen jeweils eine durchgehende Leitung bilden.According to the invention, each mold consisting of at least two molded parts has at least one air channel through which air is pressed into the emptying cavity of the mold during the removal of the excess slip, in order to avoid the creation of a negative pressure. Instead of individual air connections, according to a further feature of the invention, the air channels of all molded parts form a continuous air line when the molds are pushed together, so that the invention replaces not only the pouring line, but also the air line by openings formed accordingly in the molded parts, each of which forms a continuous line when the molds are pushed together.

Falls mit der erfindungsgemäßen Vorrichtung in jeder Form gleichzeitig mehrere sanitärkeramische Erzeugnisse hergestellt werden sollen, indem mindestens zwei voneinander getrennte Hohlräume in jeder Forin ausgebildet sind, wird mit einer erfindungsgemäßen Weiterbildung vorgeschlagen, die zwischen den senkrechten Stirnflächen jedes Formteils durchgehend ausgebildete Öffnung unterhalb und zwischen den beiden Hohlräumer. anzuordnen und mit diesen durch jeweils einen Verbindungskanal zu verbinden. Diese zwischen den beiden Hohlräumen ausgebildete Gießleitung kann beim Abziehen des überschüssigen Schlickers nach der Bildung des Scherbens zugleich für das Abfließen des überschüssigen Schlickers verwendet werden, wenn für jeden der voneinander getrennten Hohlräume ein Luftanschluß vorgesehen ist, durch welchen während des Entleerens Luft in den Hohlraum nachströmt.If, with the device according to the invention, several sanitary ceramic products are to be produced in each mold at the same time by forming at least two separate cavities in each forin, it is proposed with a further development according to the invention that the opening formed underneath and between the two between the vertical end faces of each molded part is continuous Cavities. to be arranged and connected to them by a connecting channel. This pouring line formed between the two cavities can also be used for draining off the excess slip when the excess slip is removed after the formation of the body if an air connection is provided for each of the separate cavities, through which air flows into the cavity during emptying .

Um separate Luftanschlüsse pro Hohlraum zu vermeiden, kann bei einer Weiterbildung der Erfindung jeder Hohlraum zur Außenseite des Formteils geneigt und an seiner tiefsten Stelle über ein Kanalstück mit einen Auslaufkanal verbunden sein, der jeweils parallel zur Öffnung zwischen den Stirnflächen des Formteils verläuft und bei zusammengeschobenen Formen jeweils eine Auslaufleitung für den überschüssigen Schlicker bildet. In diesem Fall wird die zwischen den Hohlräumen durchgehend angeordnete Leitung als Luftleitung verwendet, so daß separate Luftanschlüsse vermieden werden. Hierdurch entfällt auch ein Reinigen der separaten Luftanschlüsse, das beim bekannten Stand der Technik einen zusätzlichen Arbeitsaufwand bedeutet. Durch die erfindungsgemäße Weiterbildung wird somit nicht nur die Produktivität erhöht, sondern gleichzeitig der Arbeitsaufwand vereinfacht.In order to avoid separate air connections per cavity, in a further development of the invention each cavity can be inclined to the outside of the molded part and connected at its deepest point via a duct piece to an outlet duct, which runs parallel to the opening between the end faces of the molded part and when the molds are pushed together each form an outlet line for the excess slip. In this case, the one between the cavities is displayed continuously orderly line used as air line, so that separate air connections are avoided. This also eliminates the need to clean the separate air connections, which in the known prior art means additional work. The further development according to the invention not only increases productivity, but also simplifies the workload.

  • Fig. 1 einen Längsschnitt durch eine erste Ausführungsform der Vorrichtung zum Herstellen von Waschbecken, wobei drei zweiteilige Formen dargestellt sind;
  • Fig. 2 einen Schnitt gemäß der Schnittlinie II-II in Fig. 1 bei vollständig mit Schlicker gefüllter Form;
  • Fig. 3 einen der Fig. 2 entsprechenden Schnitt nach der Bildung des Scherbens während des Ausfließens des überschüssigen Schlickers und
  • Fig. 4 einen den Schnittdarstellungen nach den Figuren 2 und 3 entsprechenden Schnitt durch eine zweite Ausführungsform zur gleichzeiti- gen Erzeugung zweier Waschbecken pro Form.
Two exemplary embodiments of the device according to the invention are shown in the drawing, namely:
  • 1 shows a longitudinal section through a first embodiment of the device for producing wash basins, three three-part shapes being shown;
  • 2 shows a section along the section line II-II in FIG. 1 with the mold completely filled with slip;
  • Fig. 3 is a section corresponding to Fig. 2 after the formation of the body while the excess slip and
  • Fig. 4 shows a the sectional views of Figures 2 and 3 corresponding section through a second embodiment for g leichzeiti- gene generating two sinks per mold.

Die bei beiden Ausführungsbeispielen zum Herstellen von Waschbecken dienenden Formen bestehen jeweils aus zwei eine senkrechte Trennung aufweisenden Formteilen 1 und 2, die in Längsrichtung einer Gießbank 3 bzw. 4 nebeneinander derart abgestellt sind, daß sie paarweise Hohlräume 5 entsprechend der Form des herzustellenden Erzeugnisses bilden. Während beim Ausführungsbeispiel nach den Fig. 1 bis 3 pro Form ein Waschbecken hergestellt wird, bilden die dichtend zusammengehaltenen Formteile gemäß Fig. 4 zwei Hohlräume 5, so daß pro Form gleichzeitig zwei Waschbecken hergestellt werden.The molds used in the two exemplary embodiments for the production of wash basins each consist of two mold parts 1 and 2 which have a vertical separation and which are adjacent to one another in the longitudinal direction of a casting bench 3 and 4, respectively others are turned off so that they form cavities 5 in pairs according to the shape of the product to be manufactured. While a wash basin is produced per mold in the embodiment according to FIGS. 1 to 3, the molded parts held together in a sealing manner according to FIG. 4 form two cavities 5, so that two wash basins are produced simultaneously for each mold.

Die in Fig. 1 der besseren Übersichtigkeit wegen weggelassene, jedoch in den Fig. 2 und 3 dargestellte Gießbank 3 umfaßt ein gegenüber dem Untergestell 3a zwecks Veränderung der Neigung verstellbares Oberteil 3b. An diesem Oberteil 3b sind beim dargestellten Ausführungsbeispiel drei Laufflächen für Rollen 6 ausgebildet, die an der Unterseite einer Tragplatte 7 angeordnet sind. Auf dieser Tragplatte 7 stehen die Formteile 1 und 2, so daß diese besonders einfach in Längsrichtung der Gießbank 3 verschoben werden können.The casting bench 3 omitted in FIG. 1 for the sake of clarity, but which is shown in FIGS. 2 and 3, comprises an upper part 3b which is adjustable relative to the base 3a for the purpose of changing the inclination. In the illustrated embodiment, three running surfaces for rollers 6 are formed on this upper part 3b, which are arranged on the underside of a support plate 7. The molded parts 1 and 2 stand on this support plate 7, so that they can be moved particularly easily in the longitudinal direction of the casting bench 3.

Jedes Formteil 1 bzw. 2 weist unterhalb seines Hohlraumes 5 eine etwa waagerecht verlaufende und zwischen den senkrechten Stirnflächen des Formteils 1 bzw. 2 durchgehend ausgebildete Öffnung 8 auf, die bei zusammengeschobenen Formen sowohl mit der Öffnung 8 im zur jeweiligen Form gehörenden anderen Formteil 2 bzw. 1 als auch mit der Öffnung 8 im anschließenden Formteil der benachbarten Form abgedichtet verbunden ist. Dies geht deutlich aus Fig. 1 hervor.Each molded part 1 or 2 has, below its cavity 5, an approximately horizontal opening 8 formed continuously between the vertical end faces of the molded part 1 or 2, which when the molds are pushed together with the opening 8 in the other molded part 2 or corresponding to the respective shape 1 and is also connected in a sealed manner to the opening 8 in the subsequent molded part of the adjacent mold. This is clear from Fig. 1.

Diese Darstellung zeigt, daß die unterhalb des jeweiligen Hohlraumes 5 ausgebildeten Öffnungen 8 eine durchgehende Gießleitung bilden, wobei das jeweils vorderste Formteil 1 der auf der Gießbank 3 befindlichen Formen einen aus der freien Stirnfläche herausragenden Rohrstutzen 9 aufweist, durch den die in den Formteilen 1 und 2 durch die Öffnungen 8 gebildete Gießleitung mit einem zum nicht dargestellten Schlickerbehälter führenden Gießleitungsstück 10 verbunden wird. Jede aus den beiden Formteilen 1 und 2 gebildete Form besitzt einen Verbindungskanal 11, durch welchen die Öffnung 8 mit dem Hohlraum 5 verbunden ist.This illustration shows that the openings 8 formed below the respective cavity 5 form a continuous casting line, the foremost molded part 1 of the molds located on the casting bench 3 being a tube projecting from the free end face Connection piece 9 has, through which the pouring line formed in the molded parts 1 and 2 through the openings 8 is connected to a piece of casting line 10 leading to the slip container (not shown). Each form formed from the two molded parts 1 and 2 has a connecting channel 11 through which the opening 8 is connected to the cavity 5.

Durch die bei dichtend zusammengehaltenen Formen die Gießleitung bildenden Öffnungen 8 wird über den Rohrstutzen 9 und das Gießleitungsstück 10 Schlicker aus dem hochstehenden Schlickerbehälter in die Hohlräume 5 der Formen gedrückt, wobei dieser Schlicker über die Verbindungskanäle 11 steigend in die Hohlräume 5 eingeführt wird. Beim Füllen der Hohlräume 5 mit Schlicker kann die in den Hohlräumen 5 befindliche Luft durch die senkrechte Trennfuge entweichen, die jeweils zwischen den beiden Formteilen 1 und 2 vorhanden ist. Diese senkrechte Trennung besitzt bei zusammengeschobenen Formen eine solche Spaltweite, daß zwar Luft entweichen kann, daß aber der aufsteigende Schlicker die Fuge verschließt, so daß ein Ausfließen des Schlickers vermieden wird.Through the openings 8 forming the sealing line in a sealing manner, slip is pressed out of the upstanding slip container into the cavities 5 of the molds via the pipe socket 9 and the casting line piece 10, this slip being increasingly introduced into the cavities 5 via the connecting channels 11. When the cavities 5 are filled with slip, the air in the cavities 5 can escape through the vertical parting line which is present between the two molded parts 1 and 2. When the molds are pushed together, this vertical separation has such a gap width that air can escape, but the ascending slip closes the joint, so that the slip does not flow out.

Sobald sich der in Fig. 3 angedeutete Scherben S gebildet hat, weil das Wasser aufnehmende Material der beiden Formteile 1 und 2 eine Verfestigung des Schlickers bewirkt, wird der überschüssige Schlicker abgezogen. Dies geschieht beim Ausführungsbeispiel nach den Fig. 1 bis 3 durch die durch die Öffnungen 8 gebildete durchgehende Leitung. Zu diesem Zweck ist diese Leitung unterhalb des Hohlraumes 5 angeordnet. Damit ein vollständiges Abfließen des überschüssigen Schlickers gewährleistet wird, sind die Formteile 1 und 2 gemäß den Fig. 2 und 3 geneigt, und zwar durch eine Neigung des Oberteiles 3b gegenüber dem Untergestell 3a der Gießbank 3.As soon as the broken glass S indicated in FIG. 3 has formed because the water-absorbing material of the two molded parts 1 and 2 causes the slip to solidify, the excess slip is removed. This is done in the embodiment according to FIGS. 1 to 3 through the continuous line formed by the openings 8. For this purpose, this line is arranged below the cavity 5. So that a complete drainage of the excess slip is ensured, the molded parts 1 and 2 are inclined according to FIGS. 2 and 3, namely by an inclination of the upper part 3b ge opposite the base 3a of the casting bench 3.

Um ein vollständiges und möglichst schnelles Ausfließen des überschüssigen Schlickers zu gewährleisten, wird unter geringem Überdruck stehende Luft während des Entleerungsvorganges in die Hohlräume 5 eingeführt. Dies kann beispielsweise durch einzelne Luftanschlüsse geschehen, welche die Luft von einer parallel zur Gießbank 3 verlegten Luftleitung in jede einzelne Form führen. Beim Ausführungsbeispiel nach den Fig. 1 und 2 sind derartige einzelne Luftanschlüsse durch einen Luftkanal 12 ersetzt, der parallel zu der Öffnung 8 in jedem Formteil 1 und 2 ausgebildet ist und bei zusammengeschobenen Formen eine durchgehende Luftleitung bildet. Bei dieser in den Fig. 2 und 3 erkennbaren Ausführungsform entfällt somit auch eine zusätzliche Luftleitung, da diese durch die in den Formteilen 1 und 2 ausgebildeten Luftkanäle 12 ersetzt wird. Pro Form ist einer dieser Luftkanäle 12 mit dem Hohlraum 5 durch eine Verbindungsleitung 13 verbunden.In order to ensure that the excess slip flows out completely and as quickly as possible, air at a slight excess pressure is introduced into the cavities 5 during the emptying process. This can be done, for example, by means of individual air connections which guide the air into an individual form from an air line laid parallel to the casting bench 3. In the embodiment according to FIGS. 1 and 2, such individual air connections are replaced by an air duct 12 which is formed parallel to the opening 8 in each molded part 1 and 2 and forms a continuous air line when the molds are pushed together. In this embodiment, which can be seen in FIGS. 2 and 3, there is also no need for an additional air line, since this is replaced by the air channels 12 formed in the molded parts 1 and 2. One of these air channels 12 is connected to the cavity 5 per mold by a connecting line 13.

Durch die in den Fig. 1 bis 3 dargestellte Ausführungsform entfällt somit sowohl eine parallel zur Gießbank 3 verlegte Gießleitung als auch eine wiederum parallel hierzu verlaufende Luftleitung, so daß sich eine Verringerung des technischen Aufwandes für die Gießanlage ergibt. Neben dieser konstruktiven Vereinfachung ergibt sich jedoch weiterhin eine erhebliche Vereinfachung des Verfahrensablaufes und Arbeitsaufwandes, weil das Spülen der Gießleitung und das Anschließen der Luftanschlüsse entfallen. Die sich in den Öffnungen 8 und gegebenenfalls Luftkanälen 12 bildenden Scherben können nach dem Öffnen der Formen und dem Herausnehmen des ein Waschbecken bildenden Scherbens den Formteilen 1 und 2 entnommen werden. Da diese verfestigten Schlickerreste innerhalb der Öffnungen 8 und gegebenenfalls Luftkanäle 12 keiner Verschmutzung ausgesetzt sind, ermöglichen sie ohne Schwierigkeiten eine Wiederaufbereitung, so daß sie einem neuen Verarbeitungsprozeß zugeführt werden können und ein Verlust des teueren Materials vermieden wird. Hierdurch ergibt sich gleichzeitig eine erhebliche Vereinfachung für den Verfahrensablauf. Um eine Bildung eines Scherbens in den Verbindungskanälen 11 und Verbindungsleitungen 13 zu vermeiden, können diese durch aus Kunststoff oder Metall bestehende Rohrstücke gebildet werden, in denen sich wegen der fehlenden Wasseraufnahme kein Scherben bildet.The embodiment shown in FIGS. 1 to 3 thus eliminates both a pouring line laid parallel to the casting bench 3 and an air line again running parallel thereto, so that there is a reduction in the technical outlay for the pouring system. In addition to this design simplification, however, there is still a considerable simplification of the process sequence and workload, because there is no need to rinse the pouring line and connect the air connections. The fragments that form in the openings 8 and, if appropriate, air ducts 12 can be removed from the mold parts 1 and 2 after the molds have been opened and the shards forming a wash basin have been removed be taken. Since these solidified slip residues within the openings 8 and possibly air channels 12 are not exposed to contamination, they enable reprocessing without difficulty, so that they can be fed to a new processing process and a loss of the expensive material is avoided. This also results in a considerable simplification of the procedure. In order to avoid the formation of a cullet in the connecting channels 11 and connecting lines 13, these can be formed by pipe pieces made of plastic or metal, in which no cullet forms due to the lack of water absorption.

Bei der in den Fig. 2 und 3 dargestellten Ausführungsform ist es auch möglich, den Schlicker durch die durch die Luftkanäle 12 gebildete Leitung zuzuführen und den überschüssigen Schlicker nach Bildung des Scherbens durch die durch die Öffnungen 8 gebildete Leitung abzuziehen. Als Leitung für die Zuführung von Druckluft kommt jedoch nur die durch die Luftkanäle 12 gebildete Leitung in Frage.In the embodiment shown in FIGS. 2 and 3, it is also possible to feed the slip through the line formed by the air channels 12 and to pull off the excess slip after the formation of the body through the line formed by the openings 8. However, only the line formed by the air channels 12 can be used as a line for the supply of compressed air.

Beim Ausführungsbeispiel nach Fig. 4 umfaßt die durch zwei Formteile 14 und 15 gebildete Form zwei Hohlräume 5, mit denen jeweils ein Waschbecken erzeugt wird. Pro Form werden somit gleichzeitig zwei Waschbecken hergestellt.In the embodiment according to FIG. 4, the shape formed by two molded parts 14 and 15 comprises two cavities 5, with each of which a wash basin is produced. This means that two sinks are produced per mold at the same time.

Die Hohlräume 5 sind zur Außenseite der Formteile 14 und 15 geneigt, so daß die wiederum über Rollen 6a auf der Gießbank 4 abgestützte Tragplatte 7a im wesentlichen waagerecht ausgerichtet sein kann.The cavities 5 are inclined to the outside of the molded parts 14 and 15, so that the support plate 7a, which in turn is supported on the casting bench 4 by means of rollers 6a, can be aligned essentially horizontally.

Die zwischen den senkrechten Stirnflächen jedes Formteils 14 und 15 durchgehend ausgebildeten Öffnungen 8a, welche die Gießleitung bilden, sind unterhalb und zwischen den beiden Hohlräumen 5 angeordnet und mit diesen Hohlräumen 5 durch jeweils einen Verbindungskanal 11a verbunden, so daß beide Hohlräume 5 gleichzeitig mit Schlicker gefüllt werden können. An seiner tiefsten Stelle ist jeder zur Außenseite des Formteils 14 bzw. 15 geneigte Hohlraum 5 über ein Kanalstück 16 mit einem Auslaufkanal 17 verbunden. Jeder Auslaufkanal 17 verläuft parallel zur Öffnung 8a zwischen den Stirnflächen des jeweiligen Formteils 14 bzw. 15 und bildet bei zusammengeschobenen Formteilen 14 und 15 eine Auslaufleitung für den überschüssigen Schlicker.The openings 8a formed continuously between the vertical end faces of each molded part 14 and 15, which form the pouring line, are arranged below and between the two cavities 5 and connected to these cavities 5 by a respective connecting channel 11a, so that both cavities 5 are simultaneously filled with slip can be. At its lowest point, each cavity 5 inclined to the outside of the molded part 14 or 15 is connected to an outlet channel 17 via a channel piece 16. Each outlet channel 17 runs parallel to the opening 8a between the end faces of the respective molded part 14 and 15 and forms an outlet line for the excess slip when the molded parts 14 and 15 are pushed together.

Bei der in Fig. 4 dargestellten Ausführungsform wird somit der Schlicker über eine zentrale Gießleitung zugeführt, welche durch die Öffnungen 8a gebildet wird. Das Ausgießen des überschüssigen Schlickers geschieht durch zwei Auslaufleitungen, die durch die Auslaufkanäle 17 gebildet werden. Die Öffnungen 8a bilden zugleich die Luftleitung, durch welche während des Ausfließens des überschüssigen Schlickers Druckluft zugeführt werden kann. Beim Ausführungsbeispiel nach Fig. 4 ist es allerdings auch möglich, die durch die Auslaufkanäle 17 gebildeten Leitungen als Gießleitung zu verwenden.In the embodiment shown in FIG. 4, the slip is thus supplied via a central pouring line which is formed by the openings 8a. The excess slip is poured out through two outlet lines which are formed by the outlet channels 17. The openings 8a also form the air line through which compressed air can be supplied while the excess slip is flowing out. In the exemplary embodiment according to FIG. 4, however, it is also possible to use the lines formed by the outlet channels 17 as pouring lines.
