Abstract: The present invention relates to a tire vulcanizing press which presses to fasten an upper and a lower molds used for vulcanizing a tire by hydraulic cylinders and raises and lowers the upper mold in an up-and-down direction to remove the tire being finished a vulcanizing processing.In the tire vulcanizing press in accordance with the present invention, since the plurality of tie rods hung from the upper mold installation member are respectively connected through the lock device to the cylinder rod of the fastening cylinder and the lower mold installation member to which the fastening cylinder is fixed is pressed to rise toward the upper mold installation member, only the tie rods are positioned around the upper and the lower molds. Therefore, a maintenance of the upper and the lower molds becomes easy, and it also becomes possible to reduce the apparatus size of the tire vulcanizing press as a whole.

Abstract: A bladder bladderless-type dual-purpose tire vulcanizer wherein a lower center mechanism for the bladder type and a lower center mechanism for the bladderless type are interchangeably mounted on a lower platen which supports a lower half of a mold. An upper center mechanism for the bladderless type is vertically movably mounted, between an operating position and an upper waiting position, on an upper plate which supports an upper half of the mold. An upper bead ring for the bladder type and an upper bead ring for the bladderless type are interchangeably mounted on the upper half of the mold. Furthermore the lower center mechanism is provided with a lower bead ring, and upper and lower domes for enclosing and clamping the upper and lower platens.
