Description
P r e s s f o r m aus porösem Sintermetall, porösem Kunststoff oder porösem Porzellan für Ton, Keramik- und Porzellanmasse, Zweck: Die Erfindung hat den Zweck,._ Ton, Porzellan-oder Keramikmasse in Form zu pressen.P ressform made of porous sintered metal, porous plastic or porous porcelain for clay, ceramic and porcelain mass, purpose: The invention has the purpose of pressing clay, porcelain or ceramic mass into shape.
Stand der Bisher werden Formen aus Gips benutzt. Die Technik: Masse wird in die Form gegossen, gedreht oder gepresst. Gips ist saugfähig und entzieht der Masse in etwa einer halben. Stunde soviel Flüssigkeit, dass danach. .die Masse fest ist und aus der Form gelöst werden kann, d.h" die Form kann nur alle 30 Minuten für ein Formstück verwendet werden; der Arbeiter muß also mit einer Vielzahl von Formen arbeiten.State of the art forms made of plaster of paris are used. The technology: mass is poured, turned or pressed into the mold. Plaster of paris is absorbent and removes the mass in about half a. Hour so much liquid that afterwards. .the mass is solid and can be released from the mold, i.e. the mold can only be opened every 30 minutes used for a fitting; So the worker has to deal with a multitude of Working forms.
Kritik des Die Gipsform nutzt sich schnell ab, wird unge-Stän ea er nau und ist nach ca. 50 Formungen unbrauchbar. Technik: Es wird zuviel Ausschussproduziert.Criticism of the The plaster mold wears out quickly, becomes unge-stän ea er nau and is unusable after approx. 50 moldings. Technology: Too much waste is produced.
Aufgabe: > Die Erzeugung von Porzellansoll vereinfacht und verbilligt werden. Task: > The production of porcelain should be simplified and made cheaper.
Lösung:' Die Formhälften werden jetzt aus hartem, porösem Kunststoff oder aus porösem Sintermetall hergestellt. Deshalb kann festere Masse verwendet werden. Die Formhälften werden vor jedem Arbeitsgang mit einem Petroleumfilm überzogen. Solution: ' The mold halves are now made of hard, porous plastic or porous sintered metal. Therefore, a stronger mass can be used. The mold halves are coated with a petroleum film before each operation.
Beschreibung: Die Formhälften sind mit einer Presse verbunden. Die untere Formhälfte ist feststehend, die obere wird maschinell auf die untere gepresst. Die Masse Ton, Keramik- oder Porzellanmasse wird auf die untere Form gelegt, die bbere daraufgepresst. Description: The mold halves are connected to a press. The lower half of the mold is fixed, the upper half is mechanically pressed onto the lower half. The clay, ceramic or porcelain mass is placed on the lower mold , the bbere pressed onto it.
Wenn die Form geschlossen ist, wird aus den an beiden Formhälften angebrachten luftabsaug-Luftdruckvorrichtungen die Zuft abgesaugt. Dann wird die Form geöffnet. Der Sog in der oberen Formhälfte bleibt bestehen, in die untere Formhälfte wird Luft hineingedrückt. Sie gelangt durch die feinen Poren des porösen Formenmaterials zwischen Form und Masse. Dadurch wird die gsform= te Masse aus der unteren Formhälfte gelöst. Die nun hochgehende obere Formhälfte nimmt durch den Sog das Formstück mit nach oben. Dann wird auch in -die obere Formhälfte Luft gedrückt, das Formstück löst sich und fällt auf die daruntergehaltene Gipsplatte.When the mold is closed, the air is sucked out from the air suction and pressure devices attached to both mold halves. Then the form is opened. The suction in the upper half of the mold remains, while air is forced into the lower half of the mold. It passes through the fine pores of the porous mold material between the mold and the mass. This releases the molded mass from the lower half of the mold. The upper half of the mold, which now rises up, takes the shaped piece upwards through the suction. Then air is also pressed into the upper half of the mold, the molding loosens and falls onto the plasterboard held below.
Erzielbare Die Herstellung vieler Gipsformen fällt-weg.. Vorteile: Alle Formteile sind von gleichbleibender Qualität. Die Maschine braucht weniger Platz als die bisher benötigten Gipsformen. Sie kann mit wenigen Zusatzteilen vollautomatisch arbeiten.Achievable The production of many plaster molds is no longer necessary .. Advantages: All molded parts are of consistent quality. The machine needs less Space than the plaster molds previously required. It can be fully automated with just a few additional parts work.
