    摘要: Provided are a mold for forming a tire including a tread molding part which is configured to be opened and closed by moving a plurality of segments in a radial direction, and a tire production method using the same. In the mold, each of the segments includes a holder; a plurality of design surface dividing mold parts disposed in a circumferentially arranged manner on a radially inner side of the holder; and a plate spring member to which the plurality of the design surface are fixed and in which both ends of the plate spring member in a circumferential direction are fixed to the holder, and when the tread molding part is opened, by elastic deformation of the plate spring member, the plurality of the design surface are moved in a direction away from the holder with the plurality of the design surface dividing mold parts being rotated.

    摘要: Tire vulcanizing mold able to cooperate with a curing press, said mold comprising two shells each one molding a sidewall of the tire and a ring of sectors for molding the tread of the tire, each sector comprising a support and a molding lining situated radially on the inside of the support, in which ring the sectors, when the mold is in the closed position, are all in circumferential contact one with the next via the molding linings and in radial contact on the shells via the front ends of the linings each of which forms a face for contact with the shell, said supports and linings being produced in such a way that each support is able to take up the clamping force applied to the lining coming into contact with the shell when the mold is in the closed position when said clamping force at said contact face exceeds a given threshold that is lower than the plastic threshold of the lining.A predetermined clearance (j) is provided between the lower front face of the shell and the lower front end of the support, and in that this clearance (j) is cancelled out when the mold is in the closed position.

    摘要: The tire vulcanizing mould includes a plurality of segments for molding the outside of the tire tread. The segments are able to move radially between a position in which the mold is open and a position in which the mold is closed. The segments have frustoconical bearing surfaces that are placed radially on the outside. An axially mobile external ring, which acts on the frustoconical bearing surfaces, is placed radially on the outside of the segments in order to cause them to close and to move back from their position of closure in the mold. The external ring is radially preloaded towards the inside when the mold is in the open position.

    摘要: My pneumatic tire has a rim diameter of 20 inches or more and an aspect ratio of 60% or less, and the ratio d1/L1 is 0.15 or less. My mold for vulcanizing a tire is used to manufacture a pneumatic tire with a rim diameter of 20 inches or more and an aspect ratio of 60% or less. The mold includes a crown portion molding part and a side portion molding part separate from the crown portion molding part. The side portion molding part includes a curved portion capable of abutting a green tire. The ratio d2/L2 is 0.15 or less. Furthermore, my pneumatic tire can be manufactured using this mold for vulcanizing a tire.

    摘要: A molding element for a tire mold manufactured from a metallic powder fused together layer by layer, having a body, comprising a first surface intended to mold all or part of a tread surface of the tire and a second surface opposite to the first surface and intended to be in contact with another part of the mold, the thickness (E) of the body of the molding element being between 1 and 6 millimetres. The molding element has at least one cavity opening onto the second surface of this body. The molding element also has a plate positioned across the cavity and formed as one with the body of the molding element, being at the same level as the first surface of the body, and having at least one hole allowing air to pass between the first surface of the molding element and the second surface thereof.

    摘要: A segmented mold operator includes a main frame fixed to an upper cavity part of a tire press cavity and a control plunger with an axially movable cylinder rod that is configured to apply a squeeze pressure to the tire press cavity. A rotatable lock ring is rotatably coupled about an end of the cylinder rod and axially movable therewith. The lock ring includes a plurality of teeth radially arranged thereon to interface with a mold ring adapter via a bayonet connection. A lock ring frame is independent from the rotatable lock ring and is separated therefrom along the cylinder rod. A locking plunger is configured to selectively engage the rotatable lock ring to thereby prevent rotation of the rotatable lock ring. An electronic lock sensor is configured to electronically sense an axial position of the lock rod.
