Abstract
An improved tire vulcanizing press of the type including an upper frame, a lower frame and side frames by way of which said upper frame and said lower frame are integrally connected to one another, wherein a lower die half is fixedly mounted on the lower frame and an upper die half is fixedly secured to a raising and lowering table adapted to be raised up or lowered by means of a raising and lowering means fixedly attached to the upper frame in such a manner that the upper die half is displaced away from or toward the lower die half is disclosed, wherein the improvement consists in that a working cylinder, a spacer and a distance plate are arranged between the upper frame and the upper die half, said distance plate being adapted to move from the operative position in the vulcanizing press to the inoperative one located outward of the latter and vice versa, whereby vulcanizing operation is safely carried out with the minimized die opening in the event of malfunction caused with respect to the working cylinder.
