    1478572 Opening injection mould SOLVAY & CIE 19 May 1975 [20 May 1974] 21192/75 Heading B5A An article having a re-entrant portion is moulded, e.g. by blow-moulding, in a two-part mould the closure plane of which passes through the re-entrant portion, and removal of the article is facilitated by opening the mould in such a way as to impart to at least one of the mould halves a component of motion in a direction parallel to the closure plane of the mould when the mould has been opened sufficiently to disengage from projections, &c., on the surface of the article. A mould suitable for the process is shown in Fig. 1; mould half 1 is fixed and mould half 2 can be rotated on hinge 3, 4. As the mould opens cams 14 and 15 interact to force mould half 2 to the right; as the mould closes, cams 20 and 21 return mould half 2 to its original position. Other embodiments are described (Figs. 3 and 5, not shown) in which the movable mould half is slidably mounted on a bar which is hingedly attached to the fixed mould half; in these embodiments the movement in one direction is effected by a cam, and that in the other by an opposing spring.

    (54) FORM FOR FORMING PRODUCTS FROM PLASTICS
    lenii along the plane of the connector half-form. With such an embodiment of the mold, at its connector, the movable half-form simultaneously with rotation rotates along the plane of the connector of the half-molds, which makes it possible to make its forming, convex parts from the concave parts of the product and thereby prevent their damage.
    Fig. 1 shows a mold for molding plastic articles; Fig, 2 forms; Fig. Zodin of the embodiments of the form; 4 shows a rotated 90 kud & choke of the mold shown in FIG. 3 of FIG. 5 — another embodiment of the mold for molding plastic products
    A mold for molding plastic articles contains a fixedly mounted half-mold 1 {figure 1}, which is hinged mounted. on it, with the possibility of rotation perpendicular to the plane of the connector, the movable blank 2 and the mechanism for rotating the half-form. .
    On the half-form 2, the lugs 3 are made, which is connected to the lever of the turning mechanism (not shown) of this half-form. The fixed half-form 1 is rigidly connected to the levers 4 and 5, on which the levers 7 and 8 are pivotally mounted by means of the axles 6. To the latter, the fixed half-form 2 is attached to the latter by means of fixing bolts 9 and 10 and adjusting screws 11 and 12.
    The movable half-form 2 is mounted on the hinge axles with the possibility of axial movement along the plane of the connector of the form and is equipped with a mechanism for its movement, which is made in the form of two cams 13 and 14 interacting with each other, with the cam 13 fixed on the fixed half-form 1, and the cam 14. f mounted on axis 6 of the hinge. The fixed cam 13 comprises an inclined profiled part 15. The cam 14 (FIG. 2) also contains an inclined profiled part 16, identical to the profiled part 15 of the cam 13. The cams 13 and 14 are mounted so that their inclined parts 15 and 16 are opposite each other and in the case when the mold is closed (Fig. 1), the inclined portions 15 and 16 are moved apart by a small distance. (Two cams 13 and 14 are also provided with stops 17, which are in contact when the mold is closed. Similar two cams are also mounted on the second hinge of the form.
    Fig. 3 shows an embodiment of the form in which the movable half-form 2 is connected to the rings 7 and 8 by means of a plate 18 mounted on two axes 19 and 20, spring-loaded in axial direction.
    along the plane of the connector of the semi-sprinter by means of springs 21. In this form, the mechanism of axial movement of it is made in the form of a fixed cam 22 and connected to the movable half-form 2 of the roller 23. The cam 22 is mounted to apply 6 angles.
    In the form shown in FIG. The cam of the axial movement mechanism is made in the form of an inclined copier 24 fixed on the fixed mold 1, and the upper mold half is provided with an adjustable stop 25. The mold is also equipped with a locking device 26. °
    The mold for molding plastic articles works as follows.
    After the product has been molded into a mold, for example, by blasting or injection molding, the mold is opened by means of a mechanism for rotating the mold half. As the form begins to open, the movable half 2 begins its turning movement, and the inclined shaped parts 15 and 16 of the cams 13 and 14 approach each other. Until this inclined part is in contact, the movable half-form 2 performs only rotary motion on the hinges, which allows the relief parts of the molded product to be withdrawn without damage from the cavity of the movable half-form,
    As soon as the inclined profiled parts 15 and 16 of the cams 13 and 14 come into contact, sliding them against each other causes the mold half of the mold 2 in the axial direction to lead out / which allows the concave parts of the product to be withdrawn from the cavity of the movable half-mold 2. When the half-mold 2 is completely open. the product is removed from the mold. Then the mold is closed again. When the half-mold 2 is closed, it is returned to its original position by means of the second pair of cams mounted on the second hinge.
    When using the forms shown in FIGS. 3 and 5, the moving half-axle 2 moves axially due to the interaction of the cams 22 and 24 with the roller 23, and the half-form is returned to its original position by means of springs 21.
    The use of the proposed mold for molding plastic products will prevent damage to products having a concave part.
