摘要： A viscoelastic fluid molding material is injected into a tire tread cavity between the mold and an inflatable tread supporting body. The clearance distance between the mold and the inflatable tread supporting body is varied to increase the flow of the initial amount of fluid molding material into remote portions of the tire tread cavity and provide for the flow of the final amount of fluid molding material into gate portions while the tread supporting body is being deflected.Circumferentially spaced gates may be spaced from the centerplane of the mold and have runners extending toward the shoulders of the tread supporting body for increased flow of the initial amount of fluid molding material into remote shoulder portions of the tread cavity. Sealing rings at the side edges of the tread cavity prevent flow of fluid molding material into sidewall areas of side members of the mold.

摘要： A tire tread (74,76,194) is injection molded by increments in a mold cavity (56,58,119,224,262) having an open end (110,272) closed by a trailing end (116) of a cured section (114,228). A temperature moderating closed end (109,207,268) prevents complete curing of a trailing portion (116) of the cured section (114,228) while the rest of the section is cured. The mold (14,16,90,188,236) is opened so that the cured section (114,228) may be shifted to a position where the trailing portion (116) is clamped in the open end (110,272) of the mold cavity (56,58,119,224,262). A second section (118,228,264) is injection molded in the cavity (56,58,119,224,262) and the partially cured trailing portion (126) of the cured section (114,228,264) is cured and adhered to the leading portion (130) of the second section (114,228,264) as the second section is cured. This process may then be repeated for later sections to provide a desired length of cured tire tread stock (74,194,264). The mold (14,16,90,118,188,236) may have substantially flat molding surfaces (108) or longitudinally and curved molding surfaces (192,210,244). Mold segments (204,206,208,256,258,260) for a circumferentially curved mold cavity (224,262) may also be provided.

摘要： A method and apparatus for automatically removing an annular grooved tread from an initially closed segmented mold is described. The segmented mold has an annular cavity and a central core, and has both an axial direction and a radial direction. The method includes the steps of withdrawing a first plurality of segments, restraining radial movement of the tread at a plurality of locations from which segments have been withdrawn, withdrawing a second plurality of segments, retracting the restraint, and then removing the tread from the core by using an axially movable annular ring located above the upper half of the mold. The annular ring includes a plurality of push off devices, each device having a spring loaded radially retractable tread pusher component.

摘要： A ring tread (12) or a continuous tread (16) may be injection molded in a generally cylindrical segmental mold (20) having a core (42) and radially movable segments (46) forming a mold cavity (54). A container ring (60) is movable into engagement with the segments (46) during closing of the segmental mold (20) to retain the segments (46) during closing of the segmental mold (20) to retain the segments (46) in position during injection and curing. The container ring (60) may have an opening for a continuous tread section to extend from the mold cavity (54) through the side of the container ring (60) and through a space between two of the segments (46). Roller supports on the core (42) support the continuous tread (16) when the segmental mold (20) is opened and sections of the continuous tread (16) are shifted circumferentially through the mold cavity (54).

摘要： A nozzle assembly for mounting on a cold runner block has a cooled housing with a bore and a nozzle member with a shaft portion mounted in the bore for rotation about a bore axis. A cap portion of the nozzle member is connected to the shaft portion and has a surface for positioning close to the mold surface of a mold member. A mold cavity in the mold member has a mold orifice in the mold surface for alignment with a nozzle opening in the surface of the cap portion. The nozzle opening is positioned radially outward from the bore axis and is rotatable into alignment with the mold orifice upon rotation of the nozzle member. A nozzle passage extends from the nozzle opening to the bore for communicating a fluid molding material to the mold cavity. A spring device may be disposed between the housing and the nozzle member to urge the surface of the nozzle member towards the mold surface. A ball member with a flat sealing surface may be mounted in a spherical recess in the surface of the cap portion. The nozzle opening is in the flat sealing surface so that upon alignment of the nozzle opening with the mold orifice the ball member can rotate in the spherical recess and provide sealing engagement of the flat sealing surface with the flat mold surface of the mold member.

摘要： A cold runner block (38) has spaced drop holes (54) arranged in a selected pattern for supplying fluid molding material to nozzles (60) connected to the mold gates (62). The drop holes (54) open on nozzle runners (52) in the cold runner block (38) which are in communication with a source of fluid molding material. Close-off rods (68) are selectively positioned in the runners (52) to block the flow of fluid molding material beyond the drop holes (54) communicating with a mold (12) for an object of a particular size and shape. Drop hole plugs (66) are provided for the drop holes (54) which open on the nozzle runners (52) in the section of the runners (52) not blocked by the close-off rods (68).

Sealing rings (56) at the side edges of the tread cavity (32) prevent flow of fluid molding material (50) into sidewall areas (60) of side members (16,18) of the mold (10).
