    The spring element 11 is installed between the plate 9, the mold installation and the flange Over at the lower end of the shaft axis, while the plate 9 Mold installation is constantly shifted in the direction of the transfer plate under spring pressure.
    The shape of the edges used as a retention form for forming the outer peripheral part of the pre-shaped orifice is mounted on the plate 9 and is set in a position in which the shape of the edges is closed relative to the matrix 6 immediately below the hole 5. which opens and closes transversely with the mold setting plate 9.
    A punch 13 for forming the inner surface of the preform is connected to an element at the front end of the piston of a clamping cylinder (not shown) installed in the upper part of the support of the upper support plate 2, the front end surface
    molds for shaping the cavity together with the die 6 and the device for shaping the edges and the shoulder 16, which is made on the upper periphery of the molding surface 14 faK, that it can contact the upper surface of the device 12 for molding, and fix the edges.
    On both sides of the core form of the element 15, press shafts 17 are mounted, which pass through holes made on both sides of holes 4 and 5 and come into contact with a plate 9 of retainers. Position 18 denotes a guide pin,
    When the transfer plate 3 is stopped, the holes 4 and 5 overlap each other when the punch 13 together with the element 14 moves in the guide cylinder. The punch 13 moves to the device 12 for shaping and fixing the edges of the holes 4 and 5, the surface 15 of the mold on the front cone moving up and down, and the temperature control core 23 moving vertically mounted on the upper support plate 2 that holds the preliminary workpiece 20 between it and the shape of the edges to control the temperature. The feed preform 20 is positioned inside the device, 12 shaping the edges and the shoulder 16 moves into contact with the upper surface of the edge shaping device 12. At this time, the pressing shaft 17, which moved down with the punch 13, comes in contact with the fixation plate 9 to move down the device 12 is formed after adjusting the yawning temperature and fixing the edges together with the next working position due to the punch 13 to the matrix 6 through the pivot of the transfer plate 3, that 9. Orientation and ii molding razTakim manner matrix 6 ustroyst- Duv (Figure 5) comprises form 24 to 12 va 13 and punch 15 are closed for blow molding, mounted to form a cavity for a flat preform.

    the shoulder 46b comes into contact and presses the upper surface of the shape of the 45 edges.
    Thus, the mold setting plate 41 moves downwardly with the vertical shafts 39 against the action of the spring element 44 and comes into contact with the upper surface of the cavity of the cavity form 36. The shape of the cavity 36, the edge shape 45 and the core shape 46 are closed.
    After the mold is closed, a clamping force is applied and the molten resin is poured into the cavity from the injection device, the nozzle of which is always in contact with the hot runner 37 of the distributor sprue to form the flat preform 50. After that, the mold is opened using the clamping cylinder 49 for moving the shape of the core upwards, the plate 41 of the mold installation together with the vertical shafts 39 also returns under pressure from the spring to the lower surface of the transfer plate, and the shape 45 to remains in contact with the shoulder 46 forms the core. At this time, core 46 is molded to form the peripheral edge open.
    The inner surface of the preform is mounted on the lower side of the clamping element 47 above the upper ends of a plurality of vertical clamping rods 48, which pass through the transfer plate 33 and are arranged vertically, with the core form 46 located at the top relative to the holes 35 and 40, the front face of the core form enters into the shape of the edges of 45 to form the molding surface 46a, which forms a cavity together with the shape of the plate 41.

    the preform is between the surface of the shape of the edges of the 45, it is released from the shape of the cavity and moves with the shape of the edges in the direction of the transfer plate. After the installation of the mold mounting plate 41 in contact with the bottom surface of the transfer plate, the core mold 46 slides out of the edge mold 45 and returns to its original position, i.e. above the upper bearing plate 32. As a result, the pre-billet remains on the Kromo form 45 (shown by the dotted line in Fig. 9).

    the shoulder 46b comes into contact and presses the upper surface of the shape of the 45 edges.
    Thus, the mold setting plate 41 moves downwardly with the vertical shafts 39 against the action of the spring element 44 and comes into contact with the upper surface of the cavity of the cavity form 36. The shape of the cavity 36, the edge shape 45 and the core shape 46 are closed.
    After the mold is closed, a clamping force is applied and the molten resin is poured into the cavity from the injection device, the nozzle of which is always in contact with the sprue 37 of the hot spreader mold to form the flat preform 50. Thereafter, when the mold is opened with the clamping cylinder 49 to move the core shape upwards, the plate 41 mounting molds together with the vertical shafts 39 also return under pressure from the spring to the bottom surface of the transfer plate, and the shape 45 chrome ok remains in contact with the core shape shoulder 46b. At this time, pic
