ABSTRACT:
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.
