  5. Moule (1) pour la fabrication de pièces moulées (6), selon la revendication 4, caractérisé en ce que les pièces latérales (8a-8d) sont mobiles, par l'intermédiaire d'au moins un organe de déplacement (36), qui comprend en particulier une tige filetée (37) ou un excentrique (38), avec, par rapport à la pièce de châssis (9a-9d), une composante de déplacement orientée perpendiculairement à un côté longitudinal (L9a-L9d) de la pièce de châssis correspondante (9a-9d).
  6. Moule (1) pour la fabrication de pièces moulées (6), selon l'une des revendications précédentes, caractérisé en ce qu'une face supérieure (67) du châssis de moulage (4) définit un premier plan (68), qui est orienté parallèlement à un plan d'appui (E66) d'un support de production (66), sur lequel le moule (1) s'appuie lors de la fabrication des blocs moulés (6), et en ce qu'une face supérieure (71) de l'empreinte rapportée (2) ou des empreintes rapportées (2, 2a-2d) définit un deuxième plan (72), qui est décalé vers l'arrière, par rapport au premier plan (68), dans la direction du plan d'appui (E66), d'une distance (Z2), la ou les empreintes rapportées (2, 2a-2d) présentant en particulier un chanfrein (75), par lequel le prisonnier (15) va rejoindre la face supérieure (71) de l'empreinte rapportée (2) ou des empreintes rapportées (2, 2a-2d).
  7. Moule (1) pour la fabrication de pièces moulées (6), selon la revendication 6, caractérisé en ce qu'une face inférieure (69) du châssis de moulage (4) définit un troisième plan (70), qui est orienté parallèlement à un quatrième plan (74), lequel est défini par la face inférieure (73) de l'empreinte rapportée (2) ou des empreintes rapportées (2, 2a-2d), et se trouve à une distance (Z1) de cette face inférieure, la face inférieure (73) de l'empreinte rapportée (2) ou des empreintes rapportées (2, 2a-2d) formant une surface de contact (A73), par laquelle le moule (1), lors de la fabrication des pièces moulées, s'appuie sur le support de production (66), et le châssis de moulage (4), lors de la fabrication des pièces moulées, se trouvant à une distance (Z1) du support de production (66), la distance (Z1), entre la face inférieure (69) du châssis de moulage (4) et la face inférieure (73) de la ou des empreintes rapportées (2, 2a-2d), étant inférieure à la distance (Z2) entre la face supérieure (67) du châssis de moulage (4) et la face supérieure (71) de la ou des empreintes rapportées (2, 2a-2d).
  8. Procédé de fabrication d'un moule (1) pour la fabrication de pièces moulées (6), en particulier de pièces moulées en béton (7), dans lequel le moule (1) comprend un châssis de moulage (4), au moins une empreinte rapportée (2, 2a-2d) et un prisonnier élastique (5), procédé dans lequel le prisonnier (5) est disposé dans un espace intermédiaire (16), en forme de châssis, entre des pièces latérales (8a-8d) du châssis de moulage (4) et la ou les empreintes rapportées (2, 2a-2d), ainsi qu'éventuellement entre les empreintes rapportées (2, 2a-2d), et les assemble, caractérisé en ce qu'on réduit le volume (V) de l'espace intermédiaire (16) pendant une opération d'équilibrage de la température au cours de laquelle on chauffe le prisonnier élastique (5), sous l'effet d'un placement symétrique des pièces latérales (8a-8d) du châssis de moulage (4).
  9. Procédé selon la revendication 8, caractérisé en ce que le volume (V) de l'espace intermédiaire (16) est réduit dans une mesure telle que le prisonnier élastique (5) va subir un retrait lors de l'opération d'équilibrage de la température.
  10. Procédé selon la revendication 8 ou 9, caractérisé en ce que le volume (V) de l'espace intermédiaire (16) subit une réduction supplémentaire, après que l'on a mis fin à l'opération d'équilibrage de la température grâce à un déplacement plus poussé des pièces latérales (8a-8d) du châssis de moulage (4), pour créer des contraintes de compression dans le prisonnier élastique (5).
