Abstract

A compression mould (1) for producing individual three-dimensional articles, preferably hearing-aid earpieces, has two halves (2) and (3) in which a negative mould (8) and a positive mould (9) can be produced by means of an impression. After the production of these moulds, the impression is removed and the material forming a three-dimensional article, preferably silicone rubber is filled in, after which the halves (2, 3) are pressed together and heated, for which, in the process according to the invention, microwaves are used, which is possible because of the microwave-permeable and heat-resistant plastic material of the compression mould (1). This provides, in particular, the advantage of a considerably reduced vulcanisation time for the three-dimensional article. <IMAGE>

Description

Verfahren und Druckform zur Herstellung individueller Process and printing form for the production of individual

Plastiken, vorzugsweIse Otoplastiken Die ErfIndung betrifft ein Verfahren zur Herstellung individueller Plastiken, vorzugsweise Otoplastiken, nach dem Oberbegriff des Anspruchs 1 und eine Druckform zur Herstellung derartiger Plastiken nach dem Oberbegriff des Anspruchs 2. Plastics, preferably earmolds The invention relates to a method for the production of individual sculptures, preferably otoplastics, according to the generic term of claim 1 and a printing form for the production of such plastics after Preamble of claim 2.

Bei bekannten Verfahren, die beispielsweise aus der zur Gattungsbildung herangezogenen DE-OS 31 41 314 bekannt sind, wird zur Herstellung einer individuellen Plastik, wie insbesondere eine Otoplastik, eine aus zwei Hälften bestehende Druckform bzw. Küvette verwendet. In den Hälften der Küvette wird mittels einer Gipsfüllung und eines Abdruckes der herzustellenden Plastik eine Negativ- und eine Positivform der Plastik hergestellt. Danach wird in die Negativform das zur Herstellung der Plastik vorgesehene Material, insbesondere Silikonkautschuk, eingefüllt und die Negativform mit der Positivform geschlossen.In known methods, for example from the generic referenced DE-OS 31 41 314 are known, is used to produce an individual Plastic, such as in particular an otoplastic, a printing form consisting of two halves or cuvette used. A plaster filling is placed in the halves of the flask and an impression of the plastic to be produced, a negative and a positive form made of plastic. Then the negative mold is used to produce the Plastic provided material, in particular silicone rubber, filled and the Negative form closed with the positive form.

Beide Formen werden unter Aufbringung von Druck auf die Hälften der Küvette aneinander festgelegt und in diesem Zustand erhitzt, um das Material auszuvulkanisieren und auf diese Art und Weise die fertige Plastik herzustellen.Both forms are made by applying pressure to the halves of the Cuvette fixed to one another and heated in this state in order to vulcanize the material and in this way to produce the finished plastic.

Die für dieses Verfahren verwendete Küvette besteht aus Metall und wird in einem Ofen auf die für die Vulkanisierung erforderliche Temperatur von ungefähr 180 - 2000 C erwärmt. Hierbei ergibt sich jedoch der Nachteil, daß diese Erwärmung und die damit einhergehende Ausvulkanisierung eine nicht unbeträchtliche Zeit in Anspruch nimmt, was sich auf die Produktionsgeschwindigkeit und damit die Wirtschaftlichkeit des gattungsgemäßen Verfahrens negativ auswirkt.The cuvette used for this procedure is made of metal and is heated in an oven to approximately the temperature required for vulcanization 180 - 2000 C heated. However, this has the disadvantage that this heating and the associated vulcanization for a not inconsiderable amount of time Claim takes what affects the production speed and therefore profitability of the generic method has a negative effect.

Es ist daher Aufgabe der Erfindung, ein Verfahren und eine Druckform zur Herstellung individueller Plastiken, vorzugsweise Otoplastiken, der im Oberbegriff des Anspruchs 1 bzw. Anspruchs 2 umrissenen Gattung zu schaffen mit denen eine Verbesserung der Wirtschaftlichkeit durch Erhöhung der Produktionsgeschwindigkeit ermöglicht wird.It is therefore the object of the invention to provide a method and a printing form for the production of individual sculptures, preferably otoplastics, the generic term of claim 1 or claim 2 outlined genus with which to create an improvement the economy by increasing the production speed will.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 bzw. des Anspruchs 2 gelöst.This task is achieved by the characterizing features of the claim 1 or claim 2 solved.

Durch die Verwendung einer mikrowellendurchlässigen und hitzebeständigen Küvette wird erreicht, daß die Gießmasse mittels Mikrowellen zur Ausvulkanisierung erhitzt werden kann, was eine Verkürzung der Vulkanisationszeit von etwa 100 Minuten gegenüber dem Vulkanisationsverfahren mit der Metallküvette bewirkt. Dies hat wiederum eine erhebliche Erhöhung der Wirtschaftlichkeit des erfindungsgemäßen Verfahrens zur Folge.By using a microwave-permeable and heat-resistant Cuvette is achieved that the casting compound by means of microwaves for vulcanization can be heated, which shortens the vulcanization time by about 100 minutes compared to the vulcanization process with the metal cuvette. This in turn has a considerable increase in the economic viability of the process according to the invention result.

Daneben kann auch noch der Materialeinsatz für die Gießmasse reduziert werden, da es bei dem erfindungsgemäßen Verfahren möglich ist, einen Konterguß bzw. eine Positivform herzustellen.In addition, the use of material for the casting compound can also be reduced because it is possible with the method according to the invention to counter-cast or to make a positive form.

Es ist zwar bereits vorgeschlagen worden, das Gießmaterial mittels Mikrowellen zu vulkanisieren. Hierzu wurde die Verwendung einer ebenen mikrowellendurchlässigen Panzerglasplatte als Deckel für eine topfförmige Küvette vorgeschlagen, die jedoch den erheblichen Nachteil aufweist, daß das Herstellen einer Positivform nicht möglich ist. Daher wird bei diesem Verfahren eine Vollform der herzustellenden Plastik erzeugt, aus der die Kontur herausgefräst werden muß, weil auf der ebenen Panzerglasplatte die Herstellung einer Positivform nicht möglich ist. Das Herausfräsen der Kontur stellt jedoch einen erheblichen Aufwand dar, so daß dieses Verfahren aus praktischen und wirtschaftlichen Gesichtspunkten heraus ungeeignet ist.Although it has already been proposed, the casting material by means of Vulcanize microwaves. For this purpose, the use of a flat, microwave-permeable Armored glass plate proposed as a cover for a cup-shaped cuvette, however has the significant disadvantage that it is not possible to produce a positive form is. Therefore, in this process, a full form of the plastic to be produced is produced, from which the contour must be milled out, because on the flat armored glass plate the production of a positive form is not possible. Milling out the contour however, represents a considerable effort, so that this method is practical and is unsuitable from an economic point of view.

Anspruch 2 hat eine Druckform zur Herstellung individueller Plastiken, vorzugsweise in Form einer Küvette zum Inhalt, deren Hälften aus einem mikrowellendurchlässigen und hitzebeständigen Material bestehen. Diese Druckform weist neben der Möglichkeit, das Gußmaterial durch Mikrowellen zu erhitzen, den weiteren Vorteil auf, daß sie leichter und handlicher ist als vergleichbare Metall-Küvetten. Ferner können in die Küvette Metallmatritzen eingebettet werden, was es erstmals ermöglicht, Silikon-Plastiken für s.g. Modul-Im-Ohr-Geräte im Mikrowellenfertigungsverfahren herzustellen.Claim 2 has a printing form for the production of individual sculptures, preferably in the form of a cuvette for the contents, the halves of which are made from a microwave-permeable and heat-resistant material. In addition to the possibility of Heating the casting material by microwaves has the additional advantage that it is lighter and handier than comparable metal cuvettes. Furthermore, in the cuvette metal matrices are embedded, which for the first time enables silicone plastics for so-called Manufacture module-in-the-ear devices using the microwave manufacturing process.

Die Unteransprüche 3 - 5 haben vorteilhafte Weiterbildungen der erfindungsgemäßen Druckform zum Inhalt.The subclaims 3-5 have advantageous developments of the invention Print form to the content.

Vorzugsweise ist das Material der Druckform bis in einen Temperaturbereich von ca. 1800 C bis 2000 C hitzebeständig, so daß die erfindungsgemäße Druckform in einem breiten Temperaturbereich Anwendung finden kann.The material of the printing form is preferably up to a temperature range from approx. 1800 C to 2000 C heat-resistant, so that the invention Printing form can be used in a wide temperature range.

Zu den besonders bevorzugten Materialien gehören Kunststoffe wie beispielsweise Polysulfon, Polyamid, Polyoxymethylen, Polyester, Polycarbonat, Polyaryletherketon oder Polypropylen.Particularly preferred materials include plastics such as Polysulfone, polyamide, polyoxymethylene, polyester, polycarbonate, polyaryletherketone or polypropylene.

Das Zusammenpressen der beiden Küvettenhälften kann mechanisch, z. B. mit Hilfe einer Hydraulikpresse, erfolgen, und die Hälften können mittels der gem. Anspruch 10 vorgesehenen Spannringe aneinander festgepreßt werden.The two cuvette halves can be pressed together mechanically, e.g. B. with the help of a hydraulic press, and the halves can by means of according to claim 10 provided clamping rings are pressed together.
