    • 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 .
    • 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
