    This disclosure relates to apparatus for vulcanizing a tire, and includes a pair of generally annular split dies (1,2) which are axially movable relative to each other, and pair of generally circular supports (3, 4) surrounded by the dies. The supports include bead seats (5b) which are engageable with the axially outer sides of the tire beads so as to form a closed space between the supports and within the tire. The space is supplied with a pressure medium which is heated during vulcanization. The supports are axially movable relative to each other and to the dies. Each of the supports (3,4) has mounted thereon a plurality of pivotal members (6) which are movable into engagement with the axially inner sides of the tire beads. The pivotal members (6) press the beads tightly against the bead seats (5b) in order to form a seal between the beads and the bead seats.

    one
    The invention relates to the manufacture of shia and is intended to cure shia, in particular automotive.
    The aim of the invention is to improve the reliability of the device by fixing the beads of the tire before closing the mold, which allows you to immediately check the correctness of the pressure of the beads of the tire to the bead rings.
    FIG. 1 shows the proposed device for vulcanizing tires, the closed position (partial cut); in fig. 2 - the same, open position; in fig. 3 is a view A in FIG. in fig. 4 is a view B in FIG. 3; FIG. 5 is a section on BB of FIG. four; FIG. 6 is a view of FIG. one ; on . 7 shows an embodiment of the device.
    The tire vulcanization apparatus comprises a lifting mold with the lower 1 and upper 2 half-molds installed with relative movement, the drive for moving the upper half-molds 2 is not shown, and the lower half-form 1 is stationary and the device for sealing the tire cavity during vulcanization. The latter has axially movable bases 3 and 4 installed along the mold axis, holders 5 and 6, respectively, with axes 7 pivotally mounted on them by means of axes 7, placed on them with the possibility of rotation with two shoulders 8 and 16 in the central vertical plane of the mold. for breeding the levers of each base with the cams 10.
    The bases 3 and 4 are made in the form of disks, the holders 5 and 6 are in the form of rings mounted on the periphery of the disks. On the holder 5 is fixed the lower side ring P, and on the holder 6 - the upper side ring 12.
    The two shoulders levers 8 have elements 13 on the shoulders facing the periphery of the mold to press the beads of the tires against the side rings 11 and 12, and on the shoulders facing the center of the mold the copy elements in the form of projections 14 and grooves 15 to interact with the cams 10. The elements 13 for clamping the beads of the tire are made in the form of curved plates mounted on the levers 8 by means of axles 16 with the possibility of movement.

    relative to the arms and provided with springs 17, working in compression. Axes 16 are usually tangential to the turning path.
    levers 8. The levers 8 have grooves 18 in which, in order to bring down the group of levers of each base to the center of the mold, annular springs 19 are placed. Instead of annular springs, separate springs for each lever can be used. At least part of the plates have on the sides of the tab 20 to act on adjacent plates, which ensures centering of the plates, as well as their location exactly in a circle while clamping the beads of the tire and a uniform force on the beads. The sides of the adjacent plates are bevelled in opposite directions for smooth adhesion of the plates.
    Axes 16 have a different length (Fig. 3). In the normal position without the application of force (figure 2) elements 13
    5 on the adjacent levers 8 are located at different levels in the axial direction of the axes 16 with an offset of approximately the thickness of the plate, so the adjacent plates do not interfere with each other and
    30 can be made wide enough.
    The actuators 9 for diluting the levers are made in the form of hydraulic cylinders 21, the rods 22 of which are rigidly connected to the cams 10, the cams 10 are made in the form of rings and mounted on the bases 3 and 4 concentrically to the holders 5 and 6 with the possibility of axial movement. At the same time, on the side surface of each cam 10 there is an annular groove 23 for inserting the protrusions 14 of the levers 8 and an annular collar 24 for engaging the grooves 15 of the levers 8. The cams IO can be made in the form of annular projections 25 fixed to the ends of the bases 3 and 4. In this In this case, the holders 5 and 6 are axially movable relative to the bases and connected with the rods 22 of the hydraulic cylinders 21.
    Between the bases 3 and 4, there is a conventional heating means, including a series of heaters 26 installed around a central valve, a cable 27 driven by a motor (not shown) connected to the lower end of its shaft 28. Heaters 26 can be in the form of conventional annular 3 plate heaters, which are located with gaps for air passage. Above the heaters 26 there are stops 29 limiting the downward movement of the upper base 4 to prevent collisions of the levers 8 of the bases 3 and 4. On the half-molds 1 and 2 there are bolts 30, and on the side rings I and 12 there are projections 31 for fixing the boring rings relative to the half-shapes . The device works as follows. With an open mold, the bases 3 and 4 are retracted one from the other, and the levers 8 are springs 19 centered. On the lower side ring 11 is installed with the lower side of the raw material tire 32; then the upper base 4 is lowered until noip, until the upper side ring I2 comes into contact with the top rail of the tire 32 (Fig. 2). The hydraulic cylinders 21 of the actuators 9 are turned on, and the cams 10 begin to move axially towards each other and act on the levers B. The levers 8 are then divorced, turning relative to the axes 7 in the central vertical planes of the form from its center to the periphery, and the springs 19 are extended until the elements 13 come into contact with the beads of the tire 32 (Fig. 1). The springs 17 are compressed and, through the plates, transmit -32 with a compressive force to the beads, ensuring their snug fit to the lower 11 and upper 12 bead rings. As a result, the cavity 32 is reliably sealed. After this, the bases 3 and 4 are lowered with the tire 32 until the lower side ring is installed in the lower mold 1, then the upper mold 2 is lowered until it joins the lower mold 1. In this position the heads of the bolts 30 interact with protrusions 31, fix side rings G1 and 12 relative to the half-form 1 and 2, respectively. A working medium under pressure, such as air, is fed into the cavity of tire 32 through a channel in base 3 (not shown), which is heated by heaters 26. After the end of vulcanization, the mold is opened. To unload the tire 32, it is necessary to reduce the levers 8 to the center. This is achieved by the axial movement of the cams 10, which release the levers 8,. And the springs 19 reduce the levers 8 to the center of the mold. It is possible to forcibly rotate the levers 8 to the initial position by engaging them with the grooves 23. With the help of the springs 17 and the movable installation of the plates, the device is adjusted according to the thickness of the sides of the vulcanized tires.
