The invention relates to the manufacture of pneumatic tires and is intended to recharge molds of a multi-stage vulcanizer.

The purpose of the invention is to demonstrate device performance by reducing time and combining operations. .

FIG. 1 shows a device dp re-charging of molds; 2 - the same, side view; in fig. 3 - the same, top view; in fig. 4 — traverse with keys for removing molds with bayonet locks, a mechanism for loading a registry office (5 pokryshki and separation cylinders of vulcanised tires from upper half-molds; Fig. 5 — unloading of vulcanised tires; Fig. 6 - the same side view; Fig. 7 shows the rockers with injectors in the initial position.

The device for recharging the molds of the multi-position vulcanizer contains a driven 1 driven trolley 2 with central 3 and lateral 4 and 5 transverse beams and a frame 6 with guide grooves a. In the guiding grooves Q of the frame 6, the base 30 7 is mounted for movement, provided with a drive for reciprocally moving in the vertical direction in the form of hydraulic cylinders 8. On the base 7, by means of the bearing units 9, the cross members 10 i and 11 are rotated relative to their longitudinal axes, arranged parallel to each other and their keys 12 for opening the bayonet locks of the press mold 40. For turning the traverse 10 n 11 there are turning drives, executed in the form of torque power cylinders 13, mounted on the base at the ends of the traverse 10 and 11.45

Neither traverses 10 and 11 also mounted mechanisms 14 loading billet tires. The loading mechanisms 14 of the poppies include radially expandable cartridges 15 and hydraulic cylinders 16 for diluting the petals of the cartridges. The cartridges 15 are mounted on the bases 17, which, by means of the hinges 18, are mounted on crossbars and provided with hydraulic cylinders 19 for rotation.

The cartridges 15 are located on the guides eccentrically in the direction of the central transverse beam; 3 carts. The device has mechanisms 20 for unloading the vulcanized pokles.

Each unloading mechanism of vulcanized pokrysh1ek includes telescopic hydraulic cylinders 21 of one-sided action for detaching the vulcanized tires from the upper half-form, swivel base 22 with guide trays. 23, two stationary 24 and two clamping 25 pads. The pressure pads 25 are driven by a double acting hydraulic cylinder 26. The bases 22 of the mechanisms 21 are hinged on the brackets 27 of the side beams 4 and 5 and have the ability to rotate the vulcanised tire to the gripping point by means of hydraulic cylinders 28 hinged on the brackets 29 of the beams 4 and 5.

The upper side rings of the molds 30 (not shown) of the multi-stage vulcanizer are mounted on the guide sleeves 31 of the upper mold floor 30.

The nozzles 32 for applying anti-adhesive lubricant to the lower half-molds of the molds 30 are mounted on rotary arms 33 mounted on an axis 34 below the center of the driving carriage 2 driven by the cross-cylinder 35 and driven by a hydraulic cylinder 35. The device works as follows. A device for recharging the press molds of a multi-stage vulcanizer by means of a drive 1 is moved with tire bites to the molds 30 of the MULTIPLE VULCANIZER 36 and fixed. The movable base 7, with cross-pieces 10 and 11, is rotated along the guide grooves Q vertically downward by the hydraulic cylinders 8 to open the molds 30 and grip their upper half-molds together with vulcanised tires. Thereafter, the base 7 rises up to the level required by receiving the blanks from the overhead conveyor, and the central mechanism of the molds 30 partially stretches their diaphragms. The hydraulic cylinder 19 rotates the base 17 of the crosspiece 10 to the loading position of the blank pieces. Then, the pivoting beams 10 and 11 are turned by their torque cylinders 13 relative to their longitudinal axes by 90, so that the mold halves with curved tires turn to the sides of the central crossbar 3. Then, at the beam 11, the base 17 is rotated to the loading position of the blanks. The blanks are located over the diaphragms of the molds that are pulled up. The base 7 is lowered, the cartridges 15 place the blank blanks in the lower half-molds of the molds 30. A pre-shaping of the tire blanks is performed. During this time, the cylinders 21 open the vulcanized pokryshki from the upper half-molds, and the cylinders 28 rotate the bases 22 of the mechanisms 20 to the gripping position of the vulcanized poles, Pokryzhi enter between the stationary 24 and the pressure pads 25 of the mechanisms 20, the pads 25 press the poles 21, the base 22 back into the position of the pad of the mechanisms 20, the pads 25 press the poles 21, the base 22 back into the clamping pads of the mechanisms 20, pads 25 press the poles, the base 22 return back and the pressure pads of the mechanisms 20, pads 25 push the pockets of the vulcanized pocks. and there is removal of vulcanized pokrysh1ek from the upper side rings of the molds. The cylinders 26 are alternately discharging covers into the vulcanizer hatches onto a selection conveyor (not shown). The petals of the cartridges 15 are folded by the hydraulic cylinders 16. Thereafter, the base 7 by the hydraulic cylinders 8 together with the cross-pieces 10 and 11 are raised to the level of receiving blanks, and the base 17 of the mechanism 14 by the cross-bars 10 is turned by the hydraulic cylinders 19 to the initial position. Then, the hydraulic cylinders 13 rotate the yoke 10 and 11 to the initial position, and the hydraulic cylinders 19 rotate the bases 17 of the mechanisms 14 of the yoke 11 to the initial position. The cartridges 15 of the mechanisms 14 with collapsed petals are located under the next tire blanks. Billet tires are received from the overhead conveyor and spraying the bottom half of the molds 30 by nozzles. After receiving the blanks and spraying the molds 30 with anti-adhesive lubricant, the base 7 is lowered. The blanks are molded and the molds are closed 30. After releasing the keys 12 from the upper mold halves 30, the base 7 with the rotary traverse bars 10 and 11 rises to the level needed by the movement of the trolley 2, the device unlocks and moves to the next position molds 30 vulcanizer. The cycle of operation of the device is repeated.
