    This invention relates to mechanical engineering, in particular, to a method for manufacturing metal plastic rotors.
    The purpose of the invention is to increase the strength of the metal-plastic rotor.
    FIG. 1 schematically shows a mold; FIG. 2 is a section A-A in FIG. one; in fig. 3 - rotor, longitudinal section; in fig. 4 shaft of a rotor, longitudinal
    incision.
    The method and equipment of the metal-plastic rotor is implemented in a mold consisting of a fixed plate 1 and a backing plate 2, between which are placed the dies 3, the movable plate 4 and the signs 5, made in the form of a plate. The shaft 6 is fixed with inserts 7 and 8, which are inserted into the central holes of the plates 1 and 2. The inserts 7 and 8 and the plates 1 and 2 are fixed in a predetermined position with the help of the movable fastening plate 9 and the fixed plate 10 with adjustable bolts 1 1 and 1-2. Between inserts 7 and 8 and matrix 3 is formed
    shaping cavity 13 of the form. To the front of the shaft 6 adjoins the ejector 14, spring-loaded spring 15 and placed inside the flange 16. To the rear of the shaft 6 adjoins the nozzle 17 of the injection molding machine. Bolts 18 are provided for fastening plates 9 and 10 of the fastening. Shaft 6 is hollow with longitudinal slots 19 evenly spaced around the circumference and slots 20 in its middle part. The length of each slot 19 corresponds to the length of the groove 21 under the vanes 22. Jumpers 23 are formed between the slots 19 and 20. The inner diameter of the front of the shaft 6 is smaller than the internal diameter of its rear
    The method is carried out as follows.
    The shaft 6 with the signs 5 evenly spaced circumferentially in the slots is placed in open form in the matrix 3 so that the signs 5 enter the slots of the matrix 3, and the rear part of the shaft 6 is inserted in the insert 8. The shape closes,

    with
    00 4 the middle part of the shaft 6 enters the insert 7. The nozzle 17 of the injection molding machine abuts the bevel of the holes 24 of the front part of the shaft 6 and when injected, the material melt is fed to the slot m 20 of the shaft 6, free from signs 5. Through the slits 20 the material fills the decorating cavity 13, forming the rotor body 25 25. When the material passes through the slots 20 due to the pressure difference inside the shaft 6 and above the slots 20, the web 23 of the shaft 6 is retracted, and tensile stresses appear in them, which during cooling create in plastic reverse voltage, i.e., compression, It has a beneficial effect on the durability of the plastic and increasing the strength of the product made from it.
