    Apparatus for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities. The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container. A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape. During the transfer of the parisons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the parison. The parison transfer mechanism carries the neck molds with parison counterblow pressure delivering means as well as puff or low pressure means for either puffing the parison during its invert movement from the parison mold to the upright position at the blow mold or to help sustain the parison against collapse during invert. The ability to apply puffing air to the parison during transfer is a significant step in the forming process.

    The invention relates to the manufacture of blown glass products, such as bottles, cans, flasks, etc. d.  The closest to the invention to the technical essence and the achieved result is a device for forming glass containers, including a set of draft separable forms located on one line, a set of blown separable forms located on one line, separable gromoform rings, an air supply system for goloformormlym rings for supplying it at a low pressure into the cavity of the workpiece; a pair of transmitting consoles, mounted side-by-side with the possibility of rotation around a horizontal axis in the interval between draft and blow molds, and a mechanism for releasing blanks from blow molds 1.  Some defects in the resulting products are well known, for example, defects such as sedimentary waves on the side walls of the product and the presence of a trace at the junction of the wall sections once. pichny tol1chiny.  Other common defects are traces of a reflective plate and shear scars in the bottom of the product.  In addition / when manufacturing in the manner described above, products with a circular cross-sectional shape were obtained with an excessively thick bottom and relatively thin shoulders.  The same products, which had a rectangular cross-sectional shape or had the shape of a vial, were usually obtained with excessively thick and OoKobuniH walls and relatively thin shoulders. In fact, the various parts of virtually all the products obtained by the above method had significantly different wall thicknesses.  Therefore, for most products of a certain size and intended use, a portion of glass of excessively large size and weight was necessary to ensure that the resulting product would be sufficient. precisely thick and strong at the thinnest point to ensure the resistance of the product to normal mishandling during its intended use.  The temperature of the glass from which the product is molded. Pie,  lower than all other conditions being equal, the temperature would have been beaten if the portion of the glass were significantly smaller.  The purpose of the invention is to improve the quality of the manufactured products.  The goal is achieved by the fact that the device for forming glass containers, including a set of black separable molds located on one line, a set of blown separable molds located on one line, split grroform rings, an air supply system to throat plates for its supply under low pressure into the cavity of the workpiece, a pair of transfer consoles installed pivotally with the possibility of rotation around the horizontal axis between the draft and blow molds, and a mechanism for releasing Blow mold blanks, equipped with a device for holding pressurized air inside the billet during its transfer, are made in the form of a valve located in a throat-forming ring of a rough form.  In addition, it is equipped with an additional Elm set of blown split forms, a pair of transmitting consoles mounted hingedly with the possibility of rotation around a horizontal axis between the rough form and an additional set of blown detachable forms, as well as a mechanism for simultaneously opening and closing the throat forming rings of each set of forms .  The mechanism for simultaneous opening and closing of the throat forming rings is provided with an axis that is rotatably mounted between the transmitting console and the engine located on one of the consoles and connected to the axis, as well as extended suspensions placed opposite each other to maintain the blown half-form in the closed position, a four-link arm, connected to each of the suspensions by a horizontal axis and one of the corners of each of the links, and a mechanism for vibrating the axis relative to the mountains from the ground. directions For opening and closing the half-molds The mechanism for vibrating the axis relative to the horizontal direction for opening and closing the half-forms is made in the form of cranked levers connected to the horizontal axis, as well as a pair of connecting rods pivotally connected to the levers from the ends. and a mechanism for swiveling the connecting rods at the other end thereof, as well as a drive for communicating reciprocating motion to the connecting rods. FIG.  1 shows a glass forming machine, top view; in fig.  2, section A-A in FIG.  one; in fig.  3 shows a section BB in FIG.  1, with the blow head removed for clarity; in fig.  4 shows a section B-B in FIG.  3 (on an enlarged scale); in fig.  5 shows a section in FIG.  1, showing, in an enlarged scale and in detail, the throat-forming form and the transmission mechanism in FIG.  6 shows a plunger or a throat forming stud in the designated position, the section in FIG.  7-21 are schematic views illustrating the process of forming a billet and a bottle by the proposed device, the molding of a single product being shown.  The proposed device produces glass products, such as bottles and cans, which have a very uniform radial distribution of glass in the walls to ah.  The improved radial distribution of the glass allows the glass to be significantly reduced without reducing the strength of the product.  Since previously the counterblowing of the preform was performed with air pressure sufficient to effect a delayed counterblowing in a relatively short period of time and the glass was inflated to contact with the walls of the mold and the stopper with considerable force, when the glass was in contact with the walls of the molds and the stopper the amount of heat.  This led to the appearance of a completely thick and viscous cooled surface of the so-called glaze, or peel, which gives the workpiece some rigidity.  This made it possible not to maintain the workpiece in the inverted polosyeny after removal of the rough form and cork from it.  In this case, the workpiece could be turned over by means of transmission means transferring the workpiece to the blow mold.  Obviously, with a relatively thick crust on the workpiece, the reheat period necessary to allow the heat inside the workpiece to re-melt or re-soften the crust on the workpiece should be relatively long.  A long period of full reheat will slow down the process at the blowout position.  Reheating must be completed completely, otherwise one cannot hope to receive, when the preform is being blown, any uniform distribution of the thickness, of the walls.  If the distribution is poor, the container will be able to withstand only such pressure or mistreatment that its thinnest section can withstand.  The proposed device implements a method in which a hotter portion of glass of lower weight can be used.  A hotter portion of the glass is fed into the mold and immediately precipitated into the mold using a vacuum.  The contact time of the glass portion with the walls of the mold is minimal and the forces involved, except for the throat molding zone, are the forces of gravity.  Counter-blowing starts immediately, without diverting a significant time to reheat, since the glass has a higher temperature, and the contact time of the plunger with the walls is short.  The total time of contact of the glass with the mold may amount to a rough form.   B compared to 2.1 sec in accordance with the IS standard. The counterblow pressure is kept low to obtain a counterblow, which can be called soft-counterblow.  The term soft, which is synonymous with the expression low pressure, also has another important additional meaning, namely: the glass preform is inflated as much as is allowed.  the walls of the mold and the cork, but the glass touches these surfaces very easily.  In other words, counter-blowing is never accompanied by a significant force of contact of the workpiece with the walls of the rough form.  This results in a reduction in heat removal from the workpiece caused by heat conduction.  As a result, the preform is obtained without a thick crust of chilled glass.  In order to transfer the blank from the open-rough form to the blow molding, some support of the blank is required, which in this process is captured inside the blank by air having a pressure higher than atmospheric.  The amount of trapped air pressure will depend on the degree of stiffness needed to support the workpiece during roll-over and transfer.  It may even be desirable to inject the air jet under pressure into the workpiece to make the workpiece harder or to subject it to real bloat during transmission.  One of the advantages of using hotter portions of glass and maintaining the temperature of the walls of the workpiece somewhat higher than what is currently accepted is that the surface of the resulting product will have less sodium ions after molding,.  as a result, the glass product will be more resistant to abrasion and will have improved strength characteristics.  We offer a molding machine (FIG.  1-3) contains a horizontal table 1, which is raised above the base 2 with the help of side walls 3 and 4 and end walls 5, b and 8.  The side wall 3 has a protruding part in which the engines 7 are placed with reciprocating motion.  A cover 8 is attached to the protruding part of the wall 3, which can be removed to provide access to the space enclosed by the base 2, side and end walls 1 and the horizontal table 1.  On table 1, a section 9 of molding, blanks is installed, and so that the vertical plane 10 defining the parting line between the rough semi-molds 11 and 12 passes in the middle of the table 1 in the transverse direction.  Two blowing molds or sections 13 and 14 of the final blowout are installed on opposite sides and at the same distance from the preform molding section 9.  -. The blowing section 13 contains a pair of blown half-molds 15 and 16, and the blowing section 14 contains a pair of blowing half-forms 17 and 18.  Connector line between the half molds of both blow moldings;:; sections 13 and 14 define vertical planes that are parallel to the vertical plane 10 defining the parting line of draft half-molds.  Rough half molds are mounted on holders 19 and 20, extending along the entire length of the half molds.  Holders 19 and 20 are supported in the middle by vertical swings 21 and 22.  Swing axes 21 and 22 pass through sleeves 23 and 24 into the upper casting wheels x 25 and 26 of the four-link articulated lever mechanism that supports the rough half-molds.  The upper molded parts 25 and 26 extend horizontally parallel to the plane of the 10 half-molds, and their ends are hinged at the upper ends of the connecting links 27.  The connecting links 27 move down and have a slightly curved shape, and their lower ends are mounted on the keys on the shafts 29 and 29.  The upper castings 25 to 26 also have 21 and 22 parts extending to the outside at a right angle to the axis, which are bifurcated.  The horizontal axes 30 and 31 of the pivotally pivotally connect the stripped parts of the upper castings 25 and 26 to the upper ends of the connecting links 32, the lower ends of which are hingedly connected with the fixed elements 33 of the fastener.  The fastening elements 33 are mounted on the upper surface 1 of the horizontal axes of the shafts 28 and 29 (FIG.  2) parallel to the horizontal axis of the swing of horizontal connections of the links 32 with the elements of the 33 cores. The relative mixing of these two axes is equal to the useful length of the connecting links 25 and 26 between the upper axles 30 and 31 of the swing and the respective upper ends of the C5-link links 27.  Thus, it can be seen that the links 27, the upper casting 26, the link 32 and the fixed fastening of the shaft 29 and the fastening members 33 relative to each other constitute a four-element hinged lever mechanism that effectively ensures the movement of the half-form 12 when opened in such a way that the working surface of the half-form 12 will remain parallel to the plane 10.  When the mold 11 is moved relative to the other mold 12, the working surface of the mold 11 will be parallel to the plane 10. The blow molds 15 and 16 are similarly mounted on the holders 34 and 35, which can move relative to each other by means of a hinge four-piece bearing -constructions of the four-joint, which supports the draft half-ropes and 11 and 12 The blow-down half-shapes 17 and 18 are mounted on the holders 36 and 37, and they, in turn, are also supported by the four-bar hinges lever mechanisms of identical design with those that are shown to support draft half-molds 11 and 12 and other blown half-shapes 15 and 16.  In all the supporting half-shapes of the hinge four-shafts, the two shafts, which correspond to the shafts 28 and 29 at the forming position of the blanks, are drive elements.  These shafts are driven by hydraulic motors 38, one of which is shown in FIG.  3  Fig. 4 shows an enlarged detail of the hydraulic motor 38, which, when casting its s, will open and close the blower molds 17 and 1b, but it should be understood that a similar hydraulic motor is available to drive the shafts 28 29 in the molding section 9 of the molds and corresponding shafts in the blow section 13.  Similar shafts associated with the pressure section 14 are designated by the positions 39 and 40.  The following describes the gear mechanism between the hydraulic motor 38 and the shafts 39 and 40.  The shafts 39 and 40 are equipped with crank levers 41 and 42. As seen in FIG.  4 crank levers go down, and those parts of shafts 39 and 40, to which crank levers are attached, are wives with covers 43, the purpose of which is to prevent the broken CTQK or other material from interfering with the operation of the hydraulic motor.  There is a similar cover in sections 9 and 13.  The upper end of the hydraulic motor 38 is pivotally connected by fingers 44 and 45 to the downwardly extending fixedly supported support element 46.  Support element 46 (FIG. 3) consists of two spaced apart parts with vertical elongated grooves 47 in which the ends of the horizontal swing axis 48 are mounted for movement.  The swing axis passes through the plug 49 to which it is attached. piston, nevyi hydraulic motor rod 38.  The operation of the motor 38 will cause the reciprocating movement of the rod 50, which in turn will move the plug 49 up and down.  A pair of links 51 and 52 is connected at one end with the axis 48 of swing, and the other end with the crank levers 41 and 42.  Thus, the reciprocating movement of the piston rod 50 leads to a rotational-swinging movement of the shafts 39 and 40, which in turn will lead to opening and / or gmykaniyu half mold 17 and 18 in the blowing section 14.  As shown in FIG.  3, the ends of the 4fO shaft are supported on bearings 53 and 54.  Other mechanisms for maintaining the forms and their operation are essentially the same as those described in detail in relation to section 14.  At a specific position of the device (FIG.  1 and 2) two supporting throat forming rings (or shapes) of the mechanisms are indicated, indicated by the general position 55, one of which is at the position 9 of the molding of the blanks, and the other at the withdrawal position 13 ,.  These mechanisms for maintaining hormone-forming cadmium rings 55 are also means for vM to turn and transfer the molded blanks from the mold forms. to blown.  Maintenance mechanisms 55,.  throat-forming rings include several split-type throat rings (or-. . forms) 5b and centrally located plungers 57 (FIG. 5 and 6).  This separate gullet form has a plunger mounted along its axis, and it is clear that in the proposed device each mechanism of flipping bears four sets of gromoform rings and a plunger. In addition, the mechanism for maintaining the throat-forming rings 55 is mounted on two spaced flip-mount brackets 58 and 59.  Pereorotnye console connected with the possibility of x removal from the horizontal shaft 60 ri noMOtOH mounting bracket 61.  Vshsh 60 is supplied with end bearings 62 and 63. Close to annular bearing 63, gear 64 is mounted on shaft 60, Gear 64 is meshed with vertical rail 65, in reciprocating movement of which consoles 58 and 59 will transfer the billet held by the throat from section 9 of forming the blanks to the blowing section 14.  The throat support ring mechanism 66 in the blowing section 13 also works in the same way, which is in a position at which the transfer of the blanks is completed (Fig.  1 and 2).  A gear 68 is mounted on the left shaft 67, with which the rail 69 is engaged with, so that the supporting mechanism 66 can make a movement of the coup.  The movement of the rails 65 and 69 is carried out via links 70 and 71.  Engines 1, 12, which are double-acting or reciprocating motors, cause the output shafts 73 and 74 to rotate.  The output shafts 73 and 74 are connected to cranks 75 and 76, which in turn are pivotally connected to the lower ends of the links 70 and 71.  As shown in FIG.  2, the crank 75 moves up, and the rail 65 finds with in its upper extreme position. The rail 69 is in the lower extreme position, and the crank 76 moves vertically downwards.  A motor 72 coupled to the output shaft 74 will move the crank 76 clockwise, reversing the turning arm 77 from the blowing section 13 to the section 9 for forming blanks,.  Support elements 78 and 79 for the bottom plate are provided at the blow positions 13 and 14.  The proposed device can form containers of various sizes, therefore, the blow molds will be changed depending on the configuration of the finished product to be manufactured. In view of this, it is necessary to provide the ability to adjust the vertical position of the bottom plate remaining at the blow position.  It should also be understood that the bottom plate can be replaced on its support with bottom plates of other sizes.  The supporting members 78 and 79 have a traditional construction in which the height of the supporting mechanism can be adjusted by rotating the bevel gears 80 and 81 in the usual manner, as in the known devices.  The bevel gears 80 and 81 are engaged with the bevel gears (not shown) with a manual drive, since this adjustment is made during the initial set-up of the machine.  This adjustment remains unchanged during the operation of the machine during the manufacture of the product.  Step 9 of forming the blanks shows a similar support element 82.  The upper end of the element 82 is provided with a vacuum chamber 83.  In the upper wall 84 (FIG.  5 and 6) the vacuum chamber 83 has an opening 85.  It should be noted that the vacuum chamber 83 extends along the entire length occupied by several shaping cavities in the forming section of the blanks, and a hole 85 is provided for each of the cavities.  Above the hole 85, an upwardly extending ring member 86 is provided, having an inner wall 87 sloped down and inward.  Element 86 with a conical wall 87 designed for coupling with the lower annular conical end 88 of the plunger 57i Chamber 83 should occupy the uppermost position and come into contact with the end 88 of the plunger at the beginning of the molding cycle.  By moving the flip booms 58 and 59 to the position shown in FIG.  1 and 2, the upper wall 84 of the vacuum chamber 83 will occupy the position shown in FIG.  2 and 5, with the end 88 of the plunger 57 coming into contact with the annular element 86 on the upper wall 84 of the chamber 83.  Plunger 57 has a vertical channel 89 extending from the lower end to about half the length of the plunger.  The vertical position of the plunger 57 is provided by the guide 90.  The pressure spring 91 pushes the plunger 57 in a downward direction relative to the guide 90.  When, as shown in FIG. 5, the plunger is in contact with the annular element 86, it occupies the uppermost position, and the channel 89 communicates with the vacuum chamber 83.  A vacuum through the channel 89 and the side openings 92 passes into the | Ring chamber 93 inside the guide 90.  Chamber 93 provides the ability to create a vacuum around the upper end of the plunger 57 in the throat-shaped zone of the first ring, thereby allowing a portion of the molten glass to be vacuum deposited around the tip of the plunger 57 to the limit of the throat-forming ring (or form) 56.  After the completion of the vacuum deposition in the preform molding cycle, the vacuum chamber is lowered to the position shown in FIG.  6  In this case, the supply of vacuum to the chamber 83 may be terminated.  Under the action of the pressure spring 91, the plunger 57 moves down and the lower shoulder 94 on the plunger comes into contact with the inner ring shoulder 95 at the lower end of the plunger guide 90 for the plunger.  The collector 96 is connected to the pipeline-97 with a source of compressed air.  Collector 96 has a series of holes 98 that communicate with individual channels 99 in guide 90.  The channels 99 communicate with the chamber within the guide 90, in which (the chamber) the plunger is guided. When the plunger is in the fully retracted position, as shown in FIG.  6, the channel 100 in the plunger 57 is aligned with the channel 99, while relatively low pressure air enters the channel 100, passes through the calcinic chamber 93 and, bending around the tip of the plunger 57,. begins to inflate the molten glass, forming a bubble 101, which gradually expands until the molten glass contacts all the walls of the half-molds 11 and 12 and the barrel 102.  When the plunger moves to the position shown in FIG.  6, the vacuum apertures 92 overlap and the chamber 93 in the guideway is effectively sealed, thereby preventing leakage through the channel. Stopper 102 (FIG.  2) installed on a SW support, on which in this case four separate plugs are installed.  The mechanism for mounting and moving the support 103 is not shown, but it is clear that the plugs 102 should be located out of alignment with the shape bands when loading the cavity with portions of molten glass and so that they do not interfere with the transfer of the molded blanks from the formation position of the blanks to blown positions.  The plunger guide 90 for the plunger also bears the elongated housing 104 on the opposite side of the igg opposite from the collector: the direction which influences essentially opposite the collector.  The housing 104 closes the shaft 105.  The shaft 105 is with a water shaft (the details of which are not shown) of the mechanism for opening and closing of the throat forming forms. Shaft 105 passes between console 5B and 59 and through them.  This shaft may drive a mechanism inside the arms 58 and 59 for opening the throat forms to release the throat of the blanks at the blow position.  At one end of the shaft 105 mounted crank lever 106, to which the link 107 is hingedly attached.  Link 1 is connected to the output shaft 108 of the hydro motor 109, and the hydraulic motor 109 is attached to the bracket 110.  The reduction to the action of the glidromotor 109-will cause the shaft 105 to rotate, and it is understood that when the shaft 105 is rotated, the throat-forming forms (or rings) will open and close in a preselected sequence dictated by the molding cycle.  After transferring the blanks from the preform molding section 9 to one or the other of the blown sections -13 and 14, the throat-forming forms (or rings) are opened, releasing the preforms, which are suspended by the throat, can reheat and flow under the force of gravity.  Then the blow heads 111 and 112 are moved and, covering the throat of the preforms, inwards, the preforms supply air under pressure, which inflates the preforms to the final shape determined by the cavity profile in the blow molding form.  For convenience, the blow heads 111 and 112 are shown in their original position, and it is understood that when the vertical engine 113 or 114 is actuated, the rack 115 or 116 is in engagement with the gear.  117 or 118, the hinged four-berth 119 or 120 will operate, to which the blow head 111 or 112 is attached by means of a supporting frame 121 or 122.  After the bottles have been completely molded, the molds, for example in the blow section 14, are closed, leaving the finished container standing on the bottom plates 123, and the unloading mechanism 124 is activated, which transfers the molded bottles of the bottom plates 123 to the outside of the machine the position where the device is placed on the stationary cooling plate 125 (FIG.  20).  The unloading mechanism 124 consists of an elongated head 126, which bears on itself several (in this case, four) ticks 127, which seize the finished container by the neck below the upper end of the container.  In its middle head 126 is supported by the shaft 128 passing through the mechanical arm 129.  Inside, in a mechanical box-shaped arm 129, an asterisk is mounted on the shaft 128.  This sprocket supports the chain 130, which encloses the second sprocket 131 mounted on the shaft 132.  The shaft 132 is rotated by a gear 133, which is engaged with a rack 134 capable of moving reciprocally in the vertical direction.  The rail 134 is connected at its lower end to a link 135, the lower end of which is connected to a crank 136 mounted on a drive shaft 137, - Shaft 137 is the output shaft of a hydraulic motor 138 with reciprocating motion, which has essentially the same configuration; like engines 7 or 72.  Thus, it can be seen that in the reciprocating motion of the batten 134, the articles will be transferred from the blow position 14 to the position shown in FIG.  3, while the products will remain upright.  The tongs are opened and closed in the usual way, and the signals to the tongs come from the common timing system of the forming machine.  For a better understanding of the operation of the machine, the molding cycle (process) carried out by this machine is described below.  FIG.  7-shows the start of the cycle when the draft half-molds 11 and 12 are closed around the throat-forming forms (or rings) 56, and the mechanism 55 supporting the throat-forming rings is in the forming position of the workpiece.  The support element 82 for the vacuum chamber is in a raised position, with the vacuum chamber 83 in communication with the internal channel 89 in the plunger 57.  At this point in the molding cycle, the molten portion 139 is at the entrance to the open upper end of the rough mold.  FIG.  8 portions had already entered the mold, and the vacuum in chamber 83 provided the draft of portion 139 around the raised plunger (or throat shaping pin) 57.  FIG.  9 shows the next stage of the cycle, similar to that shown in FIG.  6, while the supporting element 82 is lowered, which allowed the spring 91 to press the plunger 57 backward, and the air from the manifold, 96 starts to blow the portion 139, forming a bubble 101 in it.  At this point, the stopper 102 closes the open upper end of the draft form.  FIG.  10, pueyr 101 has a larger size due to the incoming air from the manifold 96 under pressure, which has a relatively low pressure compared to the pressures that were previously used to obtain the preform or the so-called counterblowing of the preform. The low pressure in the collector 96 gets inside the billet until until the blank has been completely molded, as shown in FIG. eleven. After that, the plug 102 is worn into the position shown in FIG. 1 and open the rough molds 11 and 12, with the resultant pitch 140 being in a vertical position relative to the throat forming ring 56.  The pressurized air entering the preform 140 from the manifold 96 remains under higher than atmospheric pressure, thus maintaining the preform.  The thoracic rings 56 are supported by mechanism 55, which in turn is supported by the turning console 58.  There is also another turning console 59, St., zanna with supports55.  As shown in FIG.  13, the flipping console 58 will swing around the horizontal axis of the shaft 60, transferring the preforms to the blow section 14.  FIG.  14, the preform is located at the midpoint of the transfer of the preform with a flip from the preform molding section 9 to the blow section 14.  Here, too, low pressure air is stored in the internal cavity 101 of the blank 140.  In fact, it is possible to slightly inflate the workpiece during its flip, comprising the steps shown in FIG.  13-15, if it is found desirable to provide a blank having a proper shape and temperature.  After the preform has arrived at the blow position 14 shown in FIG.  15, the outer crust on it is reheated from the internal heat of the billet, and low pressure air will be released, and the billet will sag under its own weight as a result of gravity.  The blow molds 17 and 18 are closed around the blank and the bottom plate 123, as a result of which they occupy the position shown in FIG.  sixteen.  The throat-forming rings are opened and the billet is released, after which it is suspended by the throat to the outer surface of the blown half-shapes 17 and 18 at the blowing position 14.  This is shown specifically in FIG.  sixteen.  The flip console 58 is returned to the position 9 of the forming blanks.  While the billet continues to flow and reheat, the blow molds 17 and 18 impose a blow head 111 through which pressurized air enters the billet and inflates it until the final shape of the bottle is obtained (FIG.  17).  The blow head 111 is then raised and retracted from the blow position 14, with the half molds 17 and 18 diluted as shown in FIG.  19, and the packaging of the container is left standing on the bottom plate 123.  Pliers 127 grips, roll the container by the throat and transfer it from the bottom plate 123 to the top surface of the fixed cooling plate 125 (Fig.  20), through which the air passes, ensuring the hardening of the bottom of the container and its cooling, sufficient to allow it to be handled during the annealing process.  Pliers 127 uncover and loose the container. becomes on the fixed cooling plate 125.  Then, the pusher 141 pushes the container from the fixed plate 125 onto the upper surface of the conveyor 142 (FIG.  21).  This ends one full cycle of forming the container, starting from the moment the glass is supplied to the rough mold and finished moving the fully molded glass container to the conveyor, which will transfer the container from the molding machine to the place where it will be transferred for annealing.  As can be seen from the previous description of the device, counter-blowing of the workpiece can be started earlier than under the same conditions on the known device where the workpiece is deposited around the throat shaping pin or plunger, supplying pressurized air into the space above the portion of the melted Glass, due to the fact that Kuum occurs more quickly.  Cont blowing up, being soft, continues with the workpiece during the entire period of the counterravel. Early conduction of a soft counterblow is beneficial in that it allows for a higher temperature of the glass and, due to the mechanism of turning or transferring of throat rings, while maintaining excessive internal pressure inside the workpiece, preventing the flattening of the workpiece during the turn, ensures a more uniform distribution of the radial glass walls.  More controlled reheating also contributes to the production of finished packagings that have a very uniform distribution of steel in the walls.  This improved distribution significantly reduces the weight of glass containers without reducing their strength.  Claim 1.  A device for forming glass containers, including a set of black detachable forms located on one line, a set of blown separable forms located on one line, detachable separating rings, an air supply system to the peripheral rings for applying low pressure to the cavity blanks, a pair of transmitting consoles installed pivotally with the possibility of rotation around a horizontal axis between the chernbva and blow molds, and a mechanism for releasing the blanks from the blown molds, differs This is in order to improve the quality of BHpa6aTt. iBaeM5iix products, it is equipped with a device for holding air under pressure inside the workpiece during its transfer, made in the form of a valve located in the throat forming ring of the rough form.
