A tire vulcanizer including: a base which supports a lower mold; a beam which supports an upper mold; a tie rod which is disposed to be fixed to one of the base and the beam on one end side thereof and has a plurality of engaged portions provided at predetermined intervals in an axis line direction along an up-and-down direction on the other end side; engaging means which is provided at the other of the base and the beam and engaged with the engaged portion of the tie rod to restrict a movement of the tie rod in the axis line direction; and pressurizing means for pressing the lower mold and the upper mold which are in a mold-closed state, so as to perform mold-clamping.

A green tire has a symmetric profile in radial section having a radially outer tread band, two radially inner beads and two sidewalls each extended from one edge of the tread band to one of the beads. During a molding and vulcanization treatment of the green tire, a movement is imposed to the tread band with respect to the beads along a direction parallel to a rotation axis of the tire, to obtain a molded and vulcanized tire having an asymmetric profile in radial section. A mold for vulcanizing tires for vehicle wheels is also described, having a tread wall axially asymmetric with respect to a middle line plane of the mold.

A tire curing press includes a top structure and a bottom structure. Hollow squeeze cylinders that can be extended and retracted are mounted underside of the bottom structure. Squeeze columns are mounted inside respective hollow pistons that can slide inside respective cylinders. Grooves are formed at intermediate position on the columns to obtain variable heights between the top and bottom structures. Lock assemblies are assembled concentric to each column above the top structure. The lock assemblies have clamping plates capable of being pulled towards each other to engage with the grooves and to lock the top structure with the columns. Distance sensors are provided to determine a distance between the grooves of each column and the clamping plates when the squeeze cylinders are retracted. Control means are configured to independently disengage the clamping plates from the grooves of each column when a predetermined distance is sensed by the distance sensors.

A tire vulcanizing machine, rubber vulcanizing apparatus, and in particular, tire vulcanizing equipment, including a mold assembly, a ring seat assembly provided in the mold assembly, a cylinder assembly supporting the ring seat assembly, a sealing hood for sealing a gas in the mold assembly, and a driving member. A gas circulating fan is provided on the ring seat assembly; a rotating shaft for driving the gas circulating fan to rotate is provided in the cylinder assembly; the driving member drives the rotating shaft to rotate; and the sealing hood isolates the driving member.

In a rubber temperature measuring device, a temperature sensor and a biasing member are disposed in an installation hole formed in a molding surface of a mold. The temperature sensor is biased by the biasing member and a temperature detecting unit at a tip end projects from the molding surface and is not in contact with the mold. The mold is closed and vulcanized in a state in which a green tire making contact with the temperature detecting unit presses the temperature sensor against biasing force of the biasing member and an opening portion of the installation hole is blocked by the temperature detecting unit. Temperature data detected by the temperature detecting unit is input to a control unit disposed outside the mold through a communication line extending in a communicating hole communicating with the installation hole.

A tire direct-pressure shaping and electromagnetic induction heating curing method uses an inner metal mold including large and small segments, a telescoping mechanism, supporting plates attached to the segments, and induction heating coils. A cavity in the middle of the segments is filled of phase change material. The temperature of the mold rises rapidly by the thermal effect of an eddy current generated on the surface of the segments to heat the green tire. When the middle part of the segment is heated to a certain temperature, the phase change material absorbs and stores the excess heat. Therefore, the temperature of the middle part of the segment differs from one of two ends of the segment. Once the tire is cured, the inner mold in the expanded condition and the outer mold support very high pressure for the green tire together.
