    0 Each pore of the prismatic support members 23 (Fig. 5-8) is not placed on the base 2 at the injection position I and the stretching and blowing position III.
    In the central base section of the base section of the frame 47 (Fig. 5-8), the support plate 3 is made in the form of an octagonal frame attached to the upper part of the base 2 using a four-angle frame 47 and supporting elements
    0 (positions I and IV)
    Frame 47 is made with ribs 18
    The rotating disk 5 is made of cast iron in the form of a frame structure from inside 5 of which 49 and the outer 50 rings interconnected by eight steel plates 51 attached by bolts 52 to the plastic olemen at 53 (not shown). The inner ring is connected with
    0 using pigs 54, try to reduce their weight. The steel plate has two rows of drilled internal slots 55 running in tangential pressure and the slots are placed directly on the bottom surface of the steel plate 51.

    The shock absorber 62 can be rotated with the help of shaft-i 63 on the bracket b-3 Amsotisagor 52 swings 9 lateral i direction using the air cylinder 5 of the cylinder mounted on the bracket the shock absorber from: single f. by the outer ring 50, when the rotating disk 5 is stopped, then the pin 56 is brought into contact with the stopper 67, which is not pointed.
    The upper clamping plate 21 and the support plate 3, the lower locking element 15 and the lower clamping plate 19 are interconnected by means of hydraulic cylinders 24 and connecting rods 17 located on both their sides.
    The device for opening and closing the mold is controlled by the upper 24 and lower 30 hydraulic cylinders.
    A plate 69, which is connected to a shut-off cylinder 70, prevents the re-entry of the spindle 68.
    The hole for the mold 28 can be formed by returning the plate 69 to its original position and then feeding M.ac/ia under pressure into the upper chamber of the upper hydraulic cylinder 24. At this point, the pressurized oil inside the lower chamber flows into the upper chamber of the lower hydraulic cylinder 30 dl in order to move the lower locking element 15 back to the clamping plate 19. At this time, the upper 21 and lower 19 clamping plates also move upwards along with the connecting rods 17. The described opening and closing operations Closures are made using several valves provided in the hydraulic circuit. Accordingly, the device for opening and closing the mold provides for the formation of a flat jar in which the size of the neck is small.
    A device for stretching and blowing 71 is located at position III. The mold placement plate 72 is put on four binding rods 73 located on both sides of the base plate 3, which is moved up and down using a hydraulic cylinder 74 provided on the connecting plate 75.
    A device 76 for raising the tension plunger and for injecting air is mounted on the base plate 3. The temperature control device 77 is mounted on the base plate at the operating temperature control position II. The mold release device 78 is mounted on the base plate at position IV of the mold release, Injectors 44 are installed on both sides at position I.
    In the second embodiment, the implementation of the device can be reduced even in
    In this case, if the diameter of the rotating disk increases, it can be minimized not only by the inertia when the rotation stops, but also the efficiency of the device increases.
