    (54) DEVICE FOR FORMING PRODUCTS OF PLASTIC MATERIAL
    The invention relates to a device for molding plastic materials, in particular molten glass, and may find application in the building materials industry. Known molding device containing multi-mold, half of which are equipped with a flange with a screw, the flange is mounted on the bracket. The head of the screw, directed radially with a gap, enters from above into the groove on the collet half of the slide. Half of the middle part of the mold is not fixed in the axial direction, therefore, when operating, they can rise up from the collet halves and fall out. This leads to bays (seams) on glass products, which reduce their strength and quality and degrade appearance of products. Opening (loose contact) also leads to uneven wear on the floor and the middle part of the mold. Because of this, some types of hollow glassware cannot be manufactured with the help of a known molding device. In the multi-seat form, the radially floating collet eliminates the centering of the middle part of the mold relative to the rest of it. This leads to product heterogeneity. In operation, due to different heat loads, for example during machine start-up, movable landings with clearance should be provided between the mold halves and the control device (collet). The closest to the invention in technical essence and achievable. The effect is a device for forming articles of plastic material, mainly glass, containing shape valves, a mechanism for separating the valves in the form of tongs (collets) connected to the drive. The force on the flaps during the molding of the product is transmitted from the actuator through the tongs 2j. This technical solution has all the disadvantages of a single form, as described above. The aim of the invention is to improve the quality of the products and the service life of the device. The goal is achieved by the fact / that the device for FO1 1Ovanie products made of plastic material,
    the glass containing the shutters of the form; the mechanism of the connector of the shutters in the form of tongs connected to the drive is provided with at least one contact element located between the tongs and the shutters of the mold, each of which is installed with a gap in the tongs. the contact elements may be located in a plane perpendicular to the longitudinal axis of the flaps of the form and made in the form of a wedge-shaped or spherical protrusion of the tongs.
    The device can also be equipped with a spring-loaded bolt located between the contact element and the shutter of the form, and the contact element is made of a composite of parts interconnected by means of a hinge and springs.
    Figure 1 schematically shows the device, top view; in Fig.2 a section aa in fig 1; 3-5, embodiments of contact elements.
    A device for shaping glassware consists of a detachable form in the form of two flaps 1 and 2, of a mechanism 3 of flap connectors in the form of tongs 4 connected to a drive (not shown). The device also includes the blow head 5 and the pan 6. The tongs 4 rotate on a common axis. Fixes the position of the cusps of the form from turning relative to the tongs, the locking element in the form of a spring-loaded finger.
    The finger enters the hole of the rome with a gap from all sides, therefore, it can rotate around its axis within the gap around the circumference. This facilitates the mutual installation of the valves 1 and 2 forms when closing its middle part. Between the shutters of the form and each half of the tongs of the connector mechanism 3 there are contact elements 7.8 and 9.10 for transmitting the closing force, which is manifested with a common closing force passing at a right angle to the longitudinal axis of the form Fig. 2 dotted: lines). The contact elements must therefore be located in a plane perpendicular to the longitudinal axis of the cusps of the form -.
    Vzmozmozhen another version of the fit of the folds of the forms of the halves of the gluten adhesives is shown in fig.1oi 2 on the left side of the drawing). In this case, the tick halves fit only with a single contact element 11 for transmitting the closing force to both flaps in the middle part of the mold;
    Fig. 3 shows an embodiment of the control device of the contact element, for example 11.
    It is made up of two parts, interconnected by means of a hinge in the form of a piston 12 and cup springs 13, free movement of spikes on the piston rod 12.
    In this case, the position of the contact element is shown only when the form flaps are open. When closing the flaps, it shifts radially relative to them.
    The contact element can be made with a wedge-shaped 14 or spherical 15 protrusions located around the circumference. With closed or open cusps of the form, the contact elements of this design are constantly adjacent to them to transfer force
    zaykan.
    The device for forming articles may be provided with a spring-loaded bolt 16 located between the contact element 11 and the flap 1 of the mold and displaced relative to the common zone of the closing force.
    At the initial forming moment, the shutters of the mold are closed and compressed by pliers.
    During the molding cycle, the shape closing force is maintained. When the glass is molded, the tongs are turned on a common axis, freeing the sash.
    The introduction of this device will improve the quality of products, mainly glass products, and will increase the cpOKi operation of the entire device.
