Cylinders 14 and 15 are articulated to frame 1 by means of axes 19. The presence of two power cylinders 14, 15 to rotate the ring 13 more evenly distribute the forces required to close the segments 5. Each segment 5 has a pair of radial protrusions 20 for interacting with protrusions 21 formed on the inner surface of the ring 13 and intended to be perceived. radial thrust s forces arising in the mold during the tire vulcanization.
    On the sides of the segments 5, there are fastened elements 22 intended to center adjacent protrusions 20t. The elements 22 may have grooves and protrusions that fit one into the other with the segments 5 closed.
    On the bed 1, a fixed vertical guide 23 is fixed, on which a horizontal bracket 24 with a sleeve 25 is mounted with the possibility of vertical movement and rotation in the horizontal plane. The vertical guide 23 is made with a longitudinal projection a (Fig. 1, 4), and the horizontal the bracket 24 is provided with two pairs of rollers 26 and 27 for alternately interacting with the protrusion a. The length of the protrusion a is chosen such that the rollers 27 completely come off of it when the bracket 24 reaches its upper position, which allows the bracket to rotate in the horizontal plane. For vertical movement of the bracket .24, a power cylinder 28 is used, the movable body of which is made in one piece with the bracket 24. The rod 29 is made stationary, the lower end is attached to the base 1, and the upper end to the stationary vertical guide 23. The cylinder 28 has the possibility of axial movement along the rod 29 together with the bracket 24. The rollers 27 and 26 are fixed on the cylinder 28, and their axes are offset by the angle of rotation of the bracket 24.

    which is pivotally connected to plate 33 by means of axis 32. Plate 33 is mounted to rotate horizontally at the upper end of rod 29. Plate 33 is provided with a vertical pin 34, which has the ability to enter the slot 35 of the upper end of the cylinder body 28 in the upper position of the latter.
    The liner 2-5 is rigidly connected to the upper annular section 6 of the mold, which with the help of the bracket 24 is transferred from a position coaxial with the lower section 4 to a position coaxial with the holder 36 of raw tires.
    The sleeve 25 is provided with a plate 37 arranged in it concentrically with the possibility of axial movement in the form of a plate 37 with radially movable grippers 38 for holding the overboard tire during loading into the mold and during unloading from it. The plate 37 is connected to the sleeve 25 by means of vertical rods 39. The sleeve 25 has a gripping element 40 for pressing the spring 37 to the plate 37.
    The grippers 38 are hingedly connected to the plate 37 and the control member 40 by means of t g 42 and 43.

    For axial movement of the element 40, a power cylinder 46 is fastened to the end of the sleeve 25, the rod 47 of which is associated with the element 40.
    The holder 36 can receive raw tires of various sizes and ensure their long-term storage without deformation. The holder 36 is formed by forks 48 evenly spaced around the circumference, the number of which is predominantly equal to the number of grippers 38, and is provided with means for centering the top bead of the wet tire relative to the upper section 6 of the mold. This means is made in the form of oscillating levers 49 pivotally mounted in the forks 48 by means of pins 50 and having protrusions 51 at the upper ends for interacting with the top side of the raw tire and axially movable spring-loaded sections 52 retractable under the influence of the sleeve 25.
    In order to be able to be adjusted in accordance with the tire size, each plug has a guide groove 53, in which a finger, which is integrally mounted with the carrier plate 54, is displaced. To adjust the radial position of the forks 48, a cone 55 serves as a side surface acting on the latches 56 provided on each fork. The cone 55 is mounted for axial movement on a screw 57 equipped with a head 58 for turning it. To prevent the cone 55 from rotating during rotation of the screw 57, pin 59 serves.
    To ensure that the forks 48 return to their original position, there is an annular spring 60 placed in the sleeves 61, which are integral with the plugs 48. The spring 60 is pretensioned, which results in constant contact between the latches 56 and the lateral surface of the cone 55.
