    Abstract: The invention relates to a method for producing a mold for molding objects in a material, called the moldable material, whereby a pattern of the objects to be molded is used and is covered with a material, called the molding material, wherein expanded graphite is used as the molding material, the pattern ( 3 ) is covered with expanded graphite to form a continuous layer of expanded graphite or a plurality of separated layers ( 5, 6 ) of expanded graphite distributed over the pattern, and the layer(s) of expanded graphite are then compressed against the pattern so as to obtain for each layer a block of consolidated graphite which is impermeable to the moldable material. A variant of the invention consists in utilizing at least one pre-consolidated layer of expanded graphite which is recompressed in at least one direction so as to have a density ranging from 30 to 50 kg/m 3 .

    Abstract: The invention relates to a method for producing a mould for moulding objects in a mouldable material consisting in using a pattern for objects to be moulded and in coating said pattern with a moulding material. The inventive method is characterised in that it also consists in using expanded graphite in the form of a moulding material, coating the pattern (3) with said expanded graphite, thereby forming a continuous expanded graphite layer or several separated expanded graphite layers (5, 6) distributed along the pattern, in pressing the expanded graphite layer(s) against the pattern in such a way that a consolidated graphite block impermeable for the mouldable material is formed for each layer. In another variant, the inventive method consists in using at least one pre-consolidated layer made of the expanded graphite which is re-compressed at least in one direction in such a way that the density thereof ranges from 30 to 50 kg/m 3 .

    Abstract translation: 本发明涉及一种用于在可模制材料中成型物体的模具的制造方法，其中包括使用待模制物体的图案和用模制材料涂覆所述图案。 本发明的方法的特征还在于使用成型材料形式的膨胀石墨，用所述膨胀石墨涂覆图案（3），从而形成连续的膨胀石墨层或几个分离的膨胀石墨层（5,6） ）沿着图案分布，将膨胀的石墨层压在图案上，使得对于每个层形成不可渗透的可模制材料的固结石墨块。 在另一个变型中，本发明的方法在于使用由膨胀石墨制成的至少一个预固化层，其至少在一个方向上被再压缩，使得其密度范围为30至50kg / m 2 > 3 。

    Abstract: L'invention concerne un procédé de fabrication d'un moule pour le moulage d'objets en un matériau dit matériau a mouler, dans lequel on utilise un modèle des objets à mouler et on recouvre le modèle d'un matériau, dit matériau de moulage, caractérisé en ce qu'on utilise, à titre de matériau de moulage, du graphite expansé, on recouvre le modèle (3) de graphite expansé en formant une épaisseur continue de graphite expansé ou plusieurs épaisseurs (5, 6) séparées de graphite expansé réparties sur le modèle, puis on comprime la(les) épaisseur(s) de graphite expansé contre le modèle de façon à obtenir, pour chaque épaisseur, un bloc de graphite consolidé et imperméable au matériau à mouler. Une variante selon l’invention consiste à utiliser au moins une épaisseur pré-consolidée, de graphite expansé recomprimé selon au moins une direction de façon à présenter une densité comprise entre 30 et 50 kg/m 3 .
