摘要:
A tire mold or a tire mold segment can include an air compression cavity, which connects to multiple surface connection slots having dimensions between 10 and 300 microns, which can be suitable for selective removal of air in the mold. The air compression cavity, can be close to the outside ambient, allowing the air escaping the interior of the mold to be compressed, which can assist in preventing the rubber material from leaving the mold pattern surface.

A primary formed body is formed by fitting bead rings to outside end portions of a cylindrical body having a film and a carcass material disposed on an outer peripheral side of the film. A green tire is formed on a rigid inner mold by causing a center portion of the primary formed body to bulge toward an outer peripheral side, and holding the center portion by suction on the inner peripheral surface of the transferring/holding mold having a similar shape to the outer peripheral surface of the rigid inner mold, and suspending the suction with the transferring/holding mold, and transferring the primary formed body to an outer peripheral surface of a bladder. The bladder has a uniform thickness and an outer peripheral surface in a neutral state similar to a profile of an inner peripheral surface of a tire to be produced. The green tire is vulcanized.

A liquid-jet-guided laser system can be used to generate functional slots having different depth and sidewall profiles by applying active control of laser beam parameters. Blinds slots can be processed onto a workpiece, such as a tire mold or a turbine vane, for an insertion of a sipe or a sealing element, respectively. Through slots can also be processed onto a workpiece, such as a turbine element for cooling during operation or a semiconductor wafer for singulation purpose. The processing of the workpiece can include a two-step procedure, wherein the first step comprises a pre-cut. The pre-cut cuts a contour outline of a slot onto a workpiece corresponding to an element that is to be inserted into the slot. The second step comprises a removal cut to remove excess workpiece material in between the contour outline. The liquid-jet-guided laser system can employ multiple-wavelength processing of a multiple-material workpiece.

A removably attached coupling assembly can be used to be attached to a laser focus optic assembly of a liquid jet guided laser system. The coupling assembly can include a coupling body, a window assembly, and a nozzle assembly. The coupling assembly thus can allow the independent and separate servicing of the window and the nozzle. For example, to service the window, the coupling assembly can be first detached from the laser focus optic assembly, exposing the top portion of the coupling assembly. The window assembly then can be detached from the coupling assembly. The window can be removed from the window assembly for servicing, such as being repaired or replaced.

A primary formed body is formed by fitting bead rings to outside end portions of a cylindrical body having an inner liner, a film layered on an outer peripheral side of the inner liner, and a carcass material disposed on an outer peripheral side of the film. A green tire is formed on an outer peripheral surface of a rigid inner mold by prevulcanizing the inner liner in a state where a center portion of the primary formed body bulges toward an outer peripheral side, and is held by suction on an inner peripheral surface of a transferring/holding mold to the outer peripheral surface of the rigid inner mold, placing the rigid inner mold inside the primary formed body, then suspending the suction with the transferring/holding mold, and transferring the primary formed body to the outer peripheral surface of the rigid inner mold. The green tire is vulcanized.

A gas flow can be provided together with a liquid jet guided laser beam to remove accumulated liquid on the processing surface. The gas flow can be configured to have minimum interference with the liquid jet guided laser beam, while functions to blow away liquid generated by the liquid jet. Keeping the surface free from accumulated liquid can improve the efficiency of the liquid jet guided laser processing.

A tire mold comprising a pair of side plates, a pair of bead rings abutting on the side plates and a gas venting passage lying between the side plates and the bead rings, wherein each of the bead rings has: a cavity surface; an outer side surface situated opposite to the cavity surface; and an outer peripheral surface connecting the cavity surface and the outer side surface, the outer peripheral surface has two regions in a direction of a bead ring thickness, a first outer peripheral surface adjoining the cavity surface and a second outer peripheral surface adjoining the outer side surface, a first gap is lying between the first outer peripheral surface and the side plate by the presence of a knurled groove on the first outer peripheral surface, a second gap is lying between the first outer peripheral surface and the side plate by making an outside diameter of the second outer peripheral surface smaller than an outside diameter of the first outer peripheral surface, a third gap is lying between the outer side surface and the side plate by the presence of a plurality of vent grooves on the outer side surface, and the first to third gaps function as the gas venting passage.
