L'invention concerne une presse verticale pour pneumatique du type à coffre à vapeur comprenant un coffre supérieur 1 supportant un moule supérieur; un coffre inférieur 2 supportant un moule inférieur, le coffre supérieur 1 et le coffre inférieur 2 étant fermés de façon ouvrable à leurs bords de connexion respectifs; une bague de verrouillage de coffre 3; un mécanisme central 14 mobile verticalement; un vérin de serrage de moule 12; un support de vérin 13 s'étendant vers le bas à partir du coffre inférieur 2 à travers une base de presse 18; un dispositif de réglage en hauteur de moule prévu à l'extérieur d'un espace de coffre défini par les coffres supérieur 1 et inférieur 2; un moyen d'étanchement 11, 15 du milieu calorifique sous pression interposé au moins entre une surface circonférentielle externe de l'organe de montage de moule inférieur et une surface circonférentielle interne du coffre inférieur et entre les bords de connexion des coffres supérieur et inférieur. A steam done type vertical tire press includes an upper dome for holding an upper mold through an upper mold mounting member and a lower dome for holding a lower mold through a lower mold mounting member. The upper dome and the lower dome are abutted at respective connection edges. A dome ring is engagable with the connection edges of the upper and lower domes. A central mechanism is vertically movably located at a central position of the lower mold mounting member. A mold clamping cylinder has a pressure rod connected to the lower mold mounting member. A cylinder support extends downwardly from the lower dome through a press base for supporting the mold clamping cylinder. A mold height adjusting device is provided outside a dome space defined by the upper and lower domes for adjusting a height between the upper and lower molds. A heat/pressure medium seal is interposed at least between an outer circumferential surface of the loweer mold mounting member and an inner circumferential surface of the lower dome and between the connection edges of the upper and lower domes.
