The means for radial movement of the sliders are made as mounted on the sleeve 10 with the possibility of limited axial movement and connection with the means for removing the upper half-form from the working zone of the disk-14 and fixed on it obliquely to the central axis rod devices 15 s

продольными пазами 16, св занных с ползунами 12 посредством пальцев 17, которые установлены в продольных пазах 16. Пер егмещение диска 14 ограничиваетс упором 18., неподвижно закрепленным у верхнего торца втулки 10, и буртом 19 втулки 10. Диск 14 соедин етс со средством дл вьшедени верхней полуформы с помощью строп 20. На штоке 13 закреплен фланец 21 дл установки верхней полуформы 4. В устройстве имеетс диафрагменный узел 22 с эластичной диафрагмой 23 и цилиндрами 24 дл управлени .longitudinal slots 16 connected to the sliders 12 by means of fingers 17, which are mounted in longitudinal slots 16. The movement of the disk 14 is limited by a stop 18. fixedly mounted at the upper end of the sleeve 10, and a shoulder 19 of the sleeve 10. The disk 14 is connected to Entering the top half-form with the help of lines 20. A flange 21 is fixed on the stem 13 to install the upper half-form 4. The device has a diaphragm assembly 22 with an elastic diaphragm 23 and cylinders 24 for control.

Устройство работает следующим образом .The device works as follows.

В исходном положении (фиг.1) верхн полунорма 4 находитс вне рабо- , чей зоны устройства, нижн полуформа 3 цилиндрами 7 подн та вверх,In the initial position (Fig. 1), the upper seminorm 4 is outside the working area of the device, the lower half-form 3 is raised up by cylinders 7,

Claims

sectors 2 are separated from the center, cylinder 13 of the hydraulic cylinder 5 is in the upper position, pokryshka 25 is loaded into the device and is on the lower half of the mold 3, and diaphragm 23 is loaded into poker 25, the upper half of the mold 4, means for removing it from the working area mounted on the rod 13 until it stops in the flange 21 (Figures 2 and 4). When loosening the tension, the sling 20 disc 14 with inclined rods 15 fixed on it under the action of its own weight axially moves along the axis of the upper half of the mold 4. The inclined rods 15 interact with the fingers 17 of their longitudinal grooves 16J to the fingers of the central axis of the device va. The slides 12 enter the annular groove 9 formed on the column 8. At the end of the stroke, the disk 14 rests against the shoulder 19 of the sleeve 10 and stops the c. In this case, the upper half-mold 4 is rigidly connected (locked) with the rod 13 of the hydraulic cylinder 5. The working fluid is supplied under pressure into the rod cavity of the hydraulic cylinder 5 and the upper half-form 4 moves down and crimps the tire blank 25. At the end of the stroke, the rod 13 abuts against the bottom of the hydraulic cylinder 5 and the mold 4 stops. Sectors 2 are moved radially to the center (their drive is not shown) and at the end of the turn they cover the upper 4 and the lower 3 semi-extruders. Then the working fluid is supplied to the piston cavity B and the rod 13 of the hydraulic cylinder 5 with the upper half-form 4 moves upwards, and the half-form 3 through the cylinders 7 moves downwards. There is a closure of sectors 2 and half-forms 3 and 4. After that, according to the specified technological regulations, vulcanization takes place. After the end of the vulcanization cycle, the device is operated in the following order. Cylinders 24 diaphragm 23 is removed from tire 25. After that, working fluid is supplied, the pressure is fed into the cavity G of the hydraulic cylinder 5 and the rod 13 together with the upper half-form 4 moves downward, while using the cylinders 7 of the half-form 3 moves upward, crimping the tire 25 along the sides . Then, sectors 2 move radially from the center (drive not shown), freeing the tread pattern of the tire. The working fluid is then supplied under pressure to the cavity B of the hydraulic cylinder 5. The top half of the mold 4 is peeled off the tire 25 and the half of mold 4 is moved upwards, in the upper position with help, and the sling 20 with the tool for removing the top half of the mold 14 moves axially upwards with axial rods hub axles. The inclined bars 15 with the walls of their longitudinal grooves 16, interacting with the fingers 17, move the sliders 12 radially from the center. The ends of the sliders 12 emerge from the annular groove 9 of the column 8. Thus, the upper mold half and the stem 13 are opened. When the disk 14 contacts the stop 18, the upper mold half 4 rises up and out of the working area. The vulcanized tire is discharged. The device is ready to load the next tire blank and then the cycle repeats. Formula invented and.
