Abstract: An injection bladder press characterized by a bladder mold including an upper mold part, a lower mold part and a mold core; a squeeze piston for squeezing the mold when closed; and an injection unit for injecting rubber molding material into the mold to mold a bladder therein. A flexible hose is connected at one end to the mold core for movement therewith and for delivery of fluid to the mold core, and at its other end to a self-retracting hose reel operative to pay out and retract the flexible hose during movement of the mold core. A top platen is mounted to a top bolster for movement away from the top bolster to facilitate access to the injection nozzle. The mold core actuator is located with a support column depending from a moving bolster. The support column is engaged by a pressure column for transfer of mold clamping force to the moving bolster from the squeeze piston in a bottom bolster.
