Zusammenfassung:	A curing press for tires includes an upper cavity having a vertically separable upper housing and a top mold. A lower cavity is mounted on a base and forms an arrangement to provide mold height adjustment during curing. The base includes a bottom bolster structure and a bottom mold. An indexing lock ring is rotatably arranged with the bottom bolster structure for closing or opening of the top and bottom molds. The bolster structure includes squeeze cylinders having piston rods to provide mold height adjustment. A squeeze retract stop assembly is provided to restrict vertically downward movement of the bottom mold during a tire curing process. The press includes at least one locking lever and at least one indexing lock pin adapted to connect the at least one locking lever to lock holes in the bottom bolster structure wherein each lock hole corresponds to a particular mold height.
