    An injection mold device for forming an article such as footwear from a plastic material includes a two-part male die such as a boot last, a fabric liner covering the male die, and a split female die surrounding the male die in spaced relation and forming together therewith a mold cavity. Beyond the upper end of the cavity, liner retaining pins on the male die extend outwardly of the peripheral wall thereof for retaining the liner in place during the injection molding operation. One of the pins is mounted for retracting axial movement for disengaging the tip thereof from the liner, and such pin bears against a sloping bearing surface of a first removable male die part which facilitates such retracting movement upon a relative shifting of the parts. The other pins are rigidly mounted in the male die part and project into recesses of the female die having undercuts and grooves extending between the recesses and the mold cavity. The grooves, when filled, define plugs which adhere to the liner and are removable together with the liner from the rigidly mounted pins upon removal of the female die, the plugs being separated from the female die at the removal thereof.

    fixed 10 and axially movable 11 pins. In the matrix 1, opposite the fixed pins 10, sockets 12 are made, having annular grooves 14 of larger diameter near the blind ends. In the matrix 1, flat grooves 15 are made to connect the sockets 12 to the forming cavity A. The axially movable pin 11 is equipped with a means for moving it, kinematically connected with the mechanism 6 for the connector of the matrix 1 through the lever 16 and the system of rods 17. Pin 11 is installed in the movable part 4 of the block 2 with

    The invention relates to the processing of polymeric materials and is intended for the manufacture of footwear.
    The aim of the invention is to improve the quality of the shoe and to facilitate the maintenance of the form by simplifying the knitting stocking's shrinking from the middle to fix it and prevent it from turning into a mesh with the latter.
    FIG. 1 shows the shape of the cross section; in fig „2 - cast saCoGr view, from the side.
    The form for the manufacture of shoes made of elastomeric material contains a split matrix 1 and a composite shoe 2 forming the cavity-forming A, which consists of parts 3 and 4 that have an inclined plane of connector B.
    Part 4 of the block is made movable relative to part 3 and has a means 5 for moving it.
    The mold has a mechanism 6 for a separable matrix 1, which is made in the form of a drive axis 7 and its sleeves 8 and 9, which are connected with the corresponding part of the split matrix 1.
    The form also has a means for fixing the knitted stocking, which is made in the form of a zone of fixed pins 10 and an axially movable pin 11 radially located on the block 2 in the leg shaping leg. In the matrix 1, nests 12 are made
    By its interaction, with its rounded non-working end 1.8 and the inclined plane B of the connector of part 3 of block 2. In the process of opening the matrix, the pin 11 is drawn into channel 19 until its working end is flush with the surface of block 2 by the action of spring 20 The plugs formed in the slots 12 extend the leg made boot that provides automatic removal of knitted stocking with fixed pins 10. 4 h, p. f-ly, 2 ill.

    Tivi rolling pin - slot 13. For the convenience of replacing the broken pins 10 they are installed in the block on the thread.
    Nests 12 near the blind ends have annular grooves 14 of larger diameter. In the matrix 1, opposite the pins 10, there are made flat grooves 15 for connecting the sockets 13 with the forming cavity A, the flat grooves 15 are made extending to the extreme border B of the knitted stocking on the block 2.
    The axial of the movable pin 1 1 is equipped with a medium r for its movement,. kinematically connected with the mechanism 6 for the matrix connector, for example through the lever 16 and the system of connecting rods 17, the movable pin 11 is installed in the movable part 4 of the pad with the possibility of its curved non-working end 18 to interact with the inclined plane B of the connector of part 3 of the block 2. To pull out the pin - p 11 to the inoperative position in the block 2 there are a channel 19 and a spring 20 of compression. The working ends of the pins 10 and 11 have tips with a conical outer surface.
    The form works in the following way.
    On the block 2, a knitted stocking 21 is placed, which is the inner layer of the boot 22 being made. The stocking 21 in the zone of the boot's toe is deposited on the tip of the rod 10 and 11. Then the mold is closed and the mold is pressed.

    injection molding of elastomeric material of the boot 22. The elastomeric material in this case fills the forming cavity A, the sockets 12 and the flat grooves 15 to form the boot 22, the plugs 23 and the tabs 24 associated with them. The tabs 24 must reach the extreme limit In tights - stocking 21, to prevent the re-engagement of the fixed pins 10 with the knitted stocking 21 when removing the finished boot 22 s. pads 2 ..
    In the process of opening the matrix, the pin 11 is pulled into the channel 19 by the action of the spring 20 until its working end is flush with the surface of the pad 2, and the plugs 23, remaining in the matrix slots 12, stretch the boot toe, automatically removing the knitted stocking 21 from the stationary pins 10. After a certain path of movement, the parts of the shape of the plug 23 come out of the sockets 12, and the soft boot 22 separates from the die 1 and is easily and quickly removed from the shoe 2 without damage after the last connector. In this case, the stocking of the 21 pins and its flaps in the forming cavity are prevented from falling.
