Abstract
Description
La présente invention a pour objet un procédé et un dispositif de fabrication d'un produit creux en céramique avec appendice, notamment une tasse avec anse, au moyen du coulage sous pression.The present invention relates to a method and a device for manufacturing a hollow ceramic product with appendage, in particular a cup with a handle, by means of pressure casting.
Les tasses sont réalisées par différentes techniques, tout au moins pour la partie du corps de tasse, mais l'anse est généralement réalisée manuellement et plus rarement à l'aide de machines.The cups are made by different techniques, at least for the part of the cup body, but the handle is generally made manually and more rarely using machines.
Le corps de tasse est obtenu lors d'une première opération, par calibrage ou bien par coulage, puis l'anse, fabriquée par une opération séparée, est rapportée sur le corps de la tasse par "collage" homogène ou hétérogène.The cup body is obtained during a first operation, by calibration or else by pouring, then the handle, produced by a separate operation, is attached to the body of the cup by homogeneous or heterogeneous "bonding".
Les inconvénients qui en résultent sont importants puisque l'anse est modelée puis plaquée sur la face extérieure du corps de tasse, ce qui crée un point fragile car, même après cuisson, l'anse peut se désolidariser.The resulting drawbacks are significant since the handle is shaped and then pressed onto the outside of the cup body, which creates a fragile point because, even after baking, the handle can become detached.
L'esthétique de la tasse est également affectée et pour le moins limitée par la surface de liaison qui, le plus souvent, doit être importante par rapport au diamètre de l'anse, si l'on souhaite donner à la liaison une résistance mécanique suffisante.The aesthetics of the cup is also affected and at the very least limited by the connection surface which, most often, must be large compared to the diameter of the handle, if one wishes to give the connection sufficient mechanical strength .
D'autre part les différentes opérations de séchage, de finition des bords de la tasse, et de lissage de la bavure du plan de joint notamment, requièrent de nombreuses reprises du produit, ce qui conduit à des prix de revient élevés.On the other hand, the various drying operations, of finishing the edges of the cup, and of smoothing the burr of the joint plane in particular, require numerous recoveries of the product, which leads to high cost prices.
On connaît un procédé et un dispositif d'automatisa- tion du montage d'une anse sur une tasse, ces deux parties étant obtenues séparément par pressage isostatique ou bien par coulage sous pression et rapportés l'une sur l'autre par pressage isostatique.A method and a device are known for automating the mounting of a handle on a cup, these two parts being obtained separately by isostatic pressing or else by pressure casting and attached to each other by isostatic pressing.
Ce procédé et ce dispositif sont décrits dans la demande de brevet EP-A-0 480 430. This process and this device are described in patent application EP-A-0 480 430.
Dans cette demande, la tasse est réalisée dans un moule de pressage isostatique et avant de retirer cette tasse de son moule, un moule annexe, plaqué sur le premier de façon que le corps de la tasse soit tangent à ce moule annexe, permet simultanément de fabriquer et de rapporter avec une très grande pression de plaquage l'anse sur le corps de la tasse.In this request, the cup is made in an isostatic pressing mold and before removing this cup from its mold, an annex mold, pressed on the first so that the body of the cup is tangent to this annex mold, allows simultaneously fabricate and attach the handle to the body of the cup with very high pressing pressure.
On connaît également un autre procédé de fabrication par pressage isostatique, décrit dans la demande de brevet FR-A-2 540 778 qui prévoit un moule de pressage isostatique en trois parties permettant la fabrication de la tasse avec anse, en une seule opération.Another manufacturing process is also known by isostatic pressing, described in patent application FR-A-2 540 778 which provides an isostatic pressing mold in three parts allowing the manufacture of the cup with handle, in a single operation.
L'anse est réalisée à l'aide d'un mandrin mobile qui vient s'interposer dans la cavité du moule de pressage.The handle is produced using a movable mandrel which is interposed in the cavity of the pressing mold.
En effet il est nécessaire de disposer d'un mandrin expansible pour conformer l'anse sur toute sa surface avec une pression identique, même dans sa partie interne.Indeed it is necessary to have an expandable mandrel to conform the handle over its entire surface with an identical pressure, even in its internal part.
Après injection de la poudre, la pression est appliquée pour la mise en forme et le pressage de la tasse et de l'anse, puis le mandrin est retiré, ce mandrin étant- orienté perpendiculairement au plan de l'anse.After injection of the powder, pressure is applied to shape and press the cup and the handle, then the mandrel is withdrawn, this mandrel being oriented perpendicular to the plane of the handle.
Le moule est ouvert, et la tasse munie de son anse est retirée.The mold is opened, and the cup with its handle is removed.
Un tel procédé reste complexe et n'est applicable qu'au pressage isostatique.Such a process remains complex and is only applicable to isostatic pressing.
Le prix de revient de pièces réalisées de cette fa çon est très élevé.The cost price of parts produced in this way is very high.
On connaît une autre technique de fabrication dite de coulage sous pression qui est très utilisée pour les produits en céramique et surtout en porcelaine. Another manufacturing technique known as pressure casting is known which is widely used for ceramic products and especially porcelain.
De la barbotine est introduite dans un moule poreux et sous la pression de coulage, l'eau contenue dans la barbotine est extraite de cette barbotine, à travers la porosité du moule ne laissant subsister que la matière minérale conformée suivant le profil du moule et suffisamment dure et compacte pour que le produit puisse être manipulé.Slurry is introduced into a porous mold and under the pouring pressure, the water contained in the slurry is extracted from this slurry, through the porosity of the mold leaving only the mineral matter shaped according to the profile of the mold and sufficiently hard and compact so that the product can be handled.
La pression reste néanmoins très inférieure à celle qui est nécessaire au pressage isostatique.The pressure remains however much lower than that which is necessary for isostatic pressing.
Cette technique génère également des produits de qualité, avec un investissement en moules réduit par rapport au pressage isostatique, surtout que les pièces mobiles complexes telles que le mandrin expansible mobile, sont supprimées.This technique also generates quality products, with a reduced investment in molds compared to isostatic pressing, especially since complex moving parts such as the movable expanding mandrel are eliminated.
De plus la vitesse de fabrication est compatible avec les rythmes de production.In addition, the manufacturing speed is compatible with the production rhythms.
L'industrie souhaite également pouvoir fabriquer des tasses avec anse en une seule opération par coulage sous pression mais aussi réaliser successivement les étapes suivantes de fabrication telles que le séchage et la finition.The industry also wishes to be able to manufacture cups with a handle in a single operation by pressure casting, but also successively carry out the following manufacturing stages such as drying and finishing.
La présente invention a donc pour objet un procédé et un dispositif qui permettent de pallier les inconvénients de l'art antérieur et qui proposent notamment de recourir au coulage sous pression, combiné à un mode de réalisation de l'anse simultanément à la fabrication du corps de tasse.The present invention therefore relates to a method and a device which make it possible to alleviate the drawbacks of the prior art and which in particular propose to use pressure casting, combined with an embodiment of the handle simultaneously with the manufacture of the body. of cup.
La présente invention présente de nombreux avantages, notamment celui de travailler à des pressions moyennes comparées aux pressions du pressage isostatique.The present invention has many advantages, in particular that of working at average pressures compared to the pressures of isostatic pressing.
De plus, les moules sont d'un prix de revient tel que toute fabrication d'un nouveau produit de forme nouvelle peut être envisagée sans problème dtinves- tissement lourd, y compris pour des petites séries. In addition, the molds are of cost price such that any manufacture of a new product of new shape can be envisaged without problem of heavy investment, including for small series.
Comparée à la technique du coulage avec revidage, on sait que l'étant de surface obtenu par coulage sous pression est bien meilleur.Compared with the technique of casting with rewinding, it is known that the surface amount obtained by pressure casting is much better.
A cet effet, la procédé selon l'invention pour la fabrication simultanée d'un produit en céramique comprenant un corps creux avec un appendice, notamment d'une tasse avec anse, se caractérise en ce qu'on introduit de la barbotine par coulage sous pression dans un moule poreux comprenant au moins trois parties, dont la première partie constitue un mandrin support du corps creux, et les deuxième et troisième parties constituent les deux demi-parois latérales de formation du corps, l'eau étant évacuée sous l'effet de la pression de coulage à travers les parois de ce moule, et en ce qu'on retire les deuxième et troisième éléments.To this end, the method according to the invention for the simultaneous manufacture of a ceramic product comprising a hollow body with an appendage, in particular of a cup with a handle, is characterized in that slip is introduced by pouring under pressure in a porous mold comprising at least three parts, the first part of which forms a support mandrel for the hollow body, and the second and third parts constitute the two lateral half-walls for forming the body, the water being evacuated under the effect of the casting pressure through the walls of this mold, and in that the second and third elements are removed.
Selon un autre mode de réalisation, le procédé consiste à utiliser un moule en quatre parties, la quatrième partie permettant une mise en forme de ltex- térieur du fond de tasse.According to another embodiment, the method consists in using a four-part mold, the fourth part allowing the outside of the cup to be shaped.
Selon une autre caractéristique du procédé, on dé- place le produit supporté par son mandrin vers une enceinté de pré-séchage, et ensuite, devant un poste de finition.According to another characteristic of the process, the product supported by its mandrel is moved to a pre-drying enclosure, and then, in front of a finishing station.
Par ailleurs, selon une variante le pré-séchage est réalisé à l'aide d'un rayonnement micro-ondes.Furthermore, according to a variant, the pre-drying is carried out using microwave radiation.
Selon une autre variant on a recours à un jet d'air puissant.According to another variant, a powerful air jet is used.
Selon un mode de réalisation particulier de l'invention le produit est retiré du mandrin, repris et tenu par le fond, préalablement au pré-séchage, notamment en cas de retrait important.According to a particular embodiment of the invention, the product is removed from the mandrel, taken up and held by the bottom, prior to pre-drying, in particular in the event of significant shrinkage.
La présente invention a également pour objet le dispositif pour la mise en oeuvre du procédé et ce dispositif comprend un moule en au moins trois parties dont deux parties, formant la paroi latérale du produit creux, ont un plan de joint dans le plan de l'appendice, avec des réserves de profil correspondant à cet appendice et des moyens de coulage de barbotine sous pression dans ce moule.The present invention also relates to the device for implementing the method and this device comprises a mold in at least three parts, two parts of which, forming the side wall of the hollow product, have a joint plane in the plane of the appendage, with profile reserves corresponding to this appendage and means for casting slip under pressure in this mold.
Selon une autre caractéristique du dispositif, la troisième partie forme un mandrin intérieur, supportant le corps creux.According to another characteristic of the device, the third part forms an internal mandrel, supporting the hollow body.
Cette troisième partie formant mandrin est équipée d'un circuit d'air et de vide de façon à faciliter le démoulage du corps creux de ce mandrin et le moulage.This third part forming the mandrel is equipped with an air and vacuum circuit so as to facilitate demolding of the hollow body of this mandrel and molding.
Le dispositif est complété, selon une variante par une quatrième partie qui permet la mise en forme du fond du produit.The device is supplemented, according to a variant by a fourth part which allows the shaping of the bottom of the product.
Le dispositif comprend en outre des postes complémentaires de pré-séchage et de finition.The device also includes additional pre-drying and finishing stations.
Selon un mode de réalisation, le mandrin est solidaire d'un carrousel de façon à présenter le produit devant les différents postes complémentaires.According to one embodiment, the mandrel is integral with a carousel so as to present the product in front of the various complementary stations.
