The device comprises a rotating carousel, several removable molds located at a certain interval around the circumference of the carousel, the position of loading, forming glass and unloading the product, as well as the position of cooling and heating the molds; a carousel drive for supplying molds to the loading and forming positions ^ several glass feeding devices, each of which includes a glass rod loading mechanism adjacent to the loading position; devices for heating the lower ends of the glass rods and for directing the glass to the loading position; mold support, in which the lower parts of the molds are mounted, a drive mechanism including a temporary device connected to the carousel drive, with a device for cutting the ends of the rods and the loading mechanism (2].

This device has several disadvantages, which are as follows:

- during the operation of the mold, several positions pass in a single cycle, at which they are first heated and then cooled, i.e. The thermal regime of their operation is characterized by sharp temperature changes. This reduces the strength and durability of the mold;

- in addition, the design of the molds is such that products, especially jewelry (blanks of inserts), are made with a flash or a large allowance for further processing. In this case, either very accurate dosing of rez AA is necessary. in Fig. ' 2; in FIG. 4 - section BB turned in FIG. 2; in FIG. 5 is a section BB of FIG. 2; in FIG. 6 is a section GG in FIG. 5; in FIG. 7 is a section DD in FIG. 6; in FIG. 8 is a section EE in FIG. ^ 2; in FIG. 9 is a view of FIG. 4; in FIG. 10 - drive end of the camshaft, on the FCG. 11 the non-drive end of the distribution in the manufacture of small products, which is practically difficult to do, or the supply of a portion of glass is slightly larger than the finished product to ensure filling of the molds, which leads to the formation of a flake by 15 dividing.

The disadvantages of the device should also include the fact that special mechanisms are used to unload molded products from the molds, and 20 also that it is equipped with a large number of molds.

The aim of the invention is to simplify the design and improve the quality of glass products. It is achieved by the fact that the device for molding glassware containing a carousel, molds, mechanisms for gripping workpieces, feed mechanisms for workpieces, cut-off mechanisms, burners, a drive distributor roller, connecting levers, a fixed frame and a drive are provided mounted on movable brackets with electromagnetic vibrators, each mold is made of detachable half-matrices with a sharp edge, mounted together with anchors of electric vibrators on leaf springs, mounted on movable ronshteynah, wherein the mold is mounted on the frame, mechanisms ⁴⁰ for gripping workpieces are mounted on the carousel, each mechanism feeding blanks is designed as a rod, the upper end of which is fixed a fork cooperating with the mechanism for. 45 gripping the workpieces, in the middle part a spring-loaded stop interacting with a stopper mounted on the frame, and the lower end of the rod is connected via a lever to the distribution roller, 50 each piece mechanism is made in the form of knives installed with the possibility of swinging, and the shape of the cutting edges is identical to the shape edges of the bottom of the semi-matrid. 55

In FIG. 1 shows a General view of the device; in FIG. . 2 is a top view of a device without a carousel; in FIG. 3 - fold roller.

The device for forming glassware includes a rotating carousel 1 with a mechanism 2 for gripping glass rods, a drive 3, a mechanism 4 for feeding and dispensing glass, a mechanism 5 for cutting molten glass from the heated ends of the rods, gas mixers 6, a drive distribution roller 7 with cams 8.9 , 10, 11, connecting levers 12,13, 14, 15, devices for heating (burner 16) the lower ends of the glass rods, removable molds 17, frame 18.

. The mechanism 4 for feeding and dispensing glass consists of a rod 19, movable in a vertical direction, at the upper end of which a plug 20, c. the middle part is the movable stop 21 and the spring 22, and in the lower part the pin 23, interacting with the lever 12. The lever 12 is mounted on the axis

24, which is mounted on a bracket

25. The bracket 25, in turn, is mounted on the frame 18. The lever 12 has a roller 26 rolling around the cam 8. The movable stop interacts with an adjustable stopper 27 mounted on the frame 18.

The mechanism 5 for cutting molten glass from the heated ends of the rods 28 consists of interchangeable knives 29, swinging on the axles 30 together with the brackets 31 under the action of the springs 32. The brackets 31 have thrust screws 33, pressing under the action of the springs 32 on the heel 34, mounted on the upper the end of the rod 35. The rod 35 is connected with a lever 13 pivotally mounted on the bracket 36 and interacting with the cam 9 through the roller.

The removable molds 17 are made in the form of a pair of interlocking half-matrices 37 and 38 mounted on anchors 39 and with them on leaf springs 40. The springs 40 are attached to the movable brackets 41, on which electromagnets 42 are mounted. The brackets 41 are mounted on rails columns 43, pressed into the housing

44, which is fixedly mounted on the frame 18. On the housing 44 there are axles

45, pushers 46 and stops 47. The stops 47 are pressed against the heel 48 fixed on the rod 49. The rod 49 interacts with a breaking lever 14 pivotally mounted on the bracket 50 and having a roller 51 pressed against the cam 10. Springs 52 are mounted on the columns 43.

The carousel 1 consists of a central vertical shaft 53, on the upper end of which there is a bracket 54 supporting devices 2 for gripping glass rods 28. The shaft 53 with a groove 55 is mounted on a pin 56 in a sleeve 57 to which a disk 58 with rollers is attached 59, interacting with the spatial cam 60. The sleeve 57 is mounted ²⁰ on the sleeve 61. At the lower end of the shaft 53 there is a sleeve 62, in the annular groove of which rollers 63 are mounted on the lever 15.

The lever 15 is equipped with a bearing 64, mounted on an axis 65 and interacting with the cam 11. The spatial cam 60 is connected to the roller 7, and that through a chain transmission 66 with the drive 3.

Under the body 44, a receiving tray 67 for finished Products 68 is installed, and under the knives 29 there is a receiving tray 69 for excess glass.

The operation of the device is as follows.

Burners 16- light up for heating _? installed at all positions except positions by moldings with the help of mixers 6 bring to the operating mode. Then into mechanism 2 for gripping at positions. glass rods are inserted into the dosing unit and, after some time, the drive 3 is turned on. When the carousel 1 is rotated one step, the next rod is inserted, etc. until fully loaded.

From the dosing position, the rods fall to the cutting position of the end of the glass rod. After the transition to this position the carousel 1 is lowered down and heats up the lower end of the rod 28 for a vremeni.Zatem cam 9 through the roller 70 cooperates with a lever 13 which Omitting ₅ repents down the stem 35 and the stop screws 33, preloaded to the heel 34 , allow the brackets 31 to be rotated. Thus, the _t blades 29 of the cutting device rotate 710992. ₆ turning around the axis 30, under the action of the springs 32 are closed and cut off excess glass. At the same time, the lower end of the cut off rod 28 acquires a 5 shape that repeats the lower edge of the sharp edges of the semi-matrices 37 and 38. This is done so that when glass is formed, the excess glass / leaves the forming zone up and to the sides, and not 1? hit the input tray 67.

The cut off excess glass falls into the output tray 69.

After closing the knives 29, the cam 11 bumps against the bearing 64, which, together with the lever 15, lifts the shaft 53 through the rollers 63 and the sleeve 62, and with it the carousel 1 with the rods 28. The rods are removed from the cutting area. After some time, the carousel 1 by means of the spatial cam 60 through the disk 58 with rollers 59 is rotated one step.

After the carousel 1 stops, the roller 51 falls into the cavity of the cam 10, as a result of which the lever 14 is rotated and the vertical shaft 53 is lowered down, because the springs 52 mounted on the columns 43 move the brackets 41, which in turn press on the pushers 46, rigidly connected with the stops 47, which are pressed against the heel 48. The half-matrices 37 and 38 are mounted on the brackets 41, therefore, when these brackets are moved, the half-matrixes are closed, cutting off from the end of the glass rod 28, a portion of the glass melt is necessary for molding the product. The excess glass is squeezed out formed by the closed semi-matrices 37 and 38 of the forming cavity. The presence of thin sharp edges at the junction of the forming surfaces of the half-matrices, as well as the oscillation of these half-matrices under the action of electromagnets 42 together with the anchors-39, allows you to cut off the excess glass and separate it from the molded product.

The forming half-matrixes 37 and 38 are in a closed state for some time, after which the continuously rotating cam 10 presses with its protrusion on the roller 51. The roller 51 is mounted on the breaking lever 14, therefore, the lever, turning, 'raises the vertical shaft 53. As a result, the brackets 41 move apart opening the half-matrices 37 and 38, since the half-matrix connector is located vertically, when they are diluted, the molded product 68 falls into the receiving tray 67. Separation of the product 68 from the surface of the semi-matrices 37 and 38 is facilitated by the fact that the half-matrix oyanno range.

After the molded product 68 falls into the receiving tray 67, the carousel 1 is again rotated one step, and the glass rods fall into the dispensing position.

After stopping the carousel 1 proiskho- ¹⁰ dit its descent to its lower position. Then the cam 8 interacts with its protrusion with the roller 26 and lifts up the long end of the lever 12, which in turn lifts the rod ⁵ 19. The rod 19 moves together with the fork 20 and the spring 22 being pressed by the stop 21. The stop 21 moves until it contacts the stop 27 , after which the movement stops. The fork 20, continuing ^{20. To} rise upward, in its extreme position interacts with the gripping device 2 of the rod 28, which is released and under the influence of its own weight falls vertically down to the stop 21, which occupies a strictly defined position.

Thus, dosing occurs. After some time, the rod 19 starts 30 to move down. In this case, the fork 20 releases the device 2, which clamps the rod 28. In the process of further lowering, the stop 21 is squeezed from the stop 27 and occupies the extreme lower position 35.

This completes one complete molding cycle that takes place over a half-turn of the carousel. ⁴⁰

The glass feeding and metering mechanism 4 consists of a rod 19 in a vertical direction, with a fork 20 installed at the upper end, a movable stop 21 and a spring 22 in the middle part, and a pin 23 interacting with the lever 12 in the lower part. The lever 12 is set to axis 24, which is fixed to bracket 25. Bracket 25, in turn, is mounted on frame 18. Lever 12 has a roller 26 rolling around the crotch 8. A movable stop interacts with an adjustable stopper 27 mounted on frame 18. Mechanism 5 for cutting off molten glass mass from the heated ends of the rods 28 consists of interchangeable knives 29 swinging on axles 30 together with brackets 31 under the action of springs 32. On brackets 31 there are stop screws 33 pressing under the action of springs 32 on p 34, fixed on the upper end of rod 35 The rod 35 is connected to the lever 13, hinged on the bracket 36 and interacting with the cam 9 via a roller. Removable molds 17 are made in the form of a pair of closing semi-matrices 37 and 38 mounted on the housing 39 and together with them on the plate springs 40. The springs 40 are attached to the movable brackets 41, on which the electromagnets 42 are also installed. The brackets 41 are seated on the guide columns 43, pressed into the housing 44, which is fixedly mounted on the frame 18. The housing 44 has axles 45, the pushers 46 and the stops 47. The stops 47 are pressed to the pin 48 fixed on the rod 49. The rod 49 interacts with the breaking lever 14 pivotally mounted on the bracket 5O and having p The face 51 is tucked into the cam Y. On the columns 43 there are springs 52 installed. The carousel 1 consists of a central vertical shaft 53, on the upper end of which is placed a bracket 54 supporting the device 2 for gripping glass rods 28. The shaft 53 with a groove 55 is mounted on pin 56 into sleeve 57, to which is attached a disk 58 with rollers 59, interacting with a spatial cam 6O. The sleeve 57 is mounted on the tumbler 61. At the lower end of the shaft 53, there is a sleeve 62, in the annular groove of which rollers 63 are mounted, mounted on the lever 15. Stage 15 is equipped with a bearing 64, mounted on the axis 65 and interacting with the cam 11. Spatial cam 6O sv It is connected with a roller 7, and that by means of a chain drive 66 with a drive 3 ... Under the body 44, a receiving tray 67 for finished products 68 is installed, and under the blades 29 - a receiving tray 69 for excess glass mass. The operation of the device is as follows. The burners 16 are lit — for heating, installed at all positions, except for positions by molding, are brought to the operating mode by means of mixers 6. Then, glass rods are inserted into the mechanism 2 for gripping the dosing and after some time the drive 3 is turned on. When turning the carousel 1 by one step, the next rod is inserted, etc. until full load. From the dosing point of view, the rods fall to the position of trimming the end of the glass rod. After moving to this position, the carousel 1 goes down and the lower end of the stubs 28 is heated for some time. The cam 9 then, via the roller 70, interacts with the lever 13, which lowers the rod 35, and the stop screws 33, which are pressed against the finger 34, allow the brackets 31 to rotate. Thus, the knives 29 of the cutting device, turning 7 2f, rotate around the axes 30 , under the action of the springs 32, the glass mass is cut off and cut off. At the same time, the lower end of the cut rod 28 acquires a shape that repeats the lower edge of the sharp edges of semi-matrices 37 and 38. This is done with the intention that when glass is molded, the excess glass goes out of the forming area and sides, and does not fall into the receiving tray 67. Cut off the excess glass enters the receiving tray 69. After the knives are closed 29, the cam 11 slides its protrusion onto the bearing 64, which together with the lever 15 through the rollers 63 and the sleeve 62 lifts up the shaft 53, and with it the carousel 1 with brushes 28. The rods are withdrawn from the trimming zone. After a period of time, the carousel 1, by means of the spatial cam 60, rotates one step through the disk 58 with the rollers 59. After stopping the carousel 1, the roller 51 falls into the trough of the cam 1O, as a result of which the lever 14 rotates and the vertical shaft 53 is lowered downwards. the springs 52 mounted on columns 43 move the brackets 41, which in turn press against the push rods 46, rigidly connected with the stops 47, pressed against the clamp 48. The semi-matrixes 37 and 38 are mounted on the brackets 41, nosTONty while moving these. The semi-matrix brackets are closed; the compartment from the end of the glass rod 28 is a portion of the glass mass necessary to form the product. The excess glass expels from the outside formed by the closed semi-matrix 37 and 38 of the forming cavity. The presence of TOHKRX sharp edges at the junction line of the molding surfaces of the semi-matrix, as well as the oscillation of these semi-matrices under the action of electromagnets 42 together with the crust-39, allows to cut off the excess glass and its from the molded product. Forming semi-matrices 37 and 38 for some time were in a closed state, after which the continuously rotating cam 1O presses its projection on the roller 51. The roller 51 is mounted on the breaking lever 14, therefore the lever, turning, raises up the vertical shaft 53. As a result the brackets 41 move apart, opening the half-matrix 37 38, Since the semi-matrix connector is located vertically, the molded product 68 pulls into the receiving tray 67 at R dilution, the separation of the product 68 from the surface of the semi-matrix 37 and 38 is prompted by the semi-matrix constantly fluctuating. After the molded article 68 is inserted into the receiving tray 67, the carousel 1 is rotated again to one of the glass rods at the dispensing position. After stopping the carousel 1, it lowers to the lower position. Here, the cam 8 interacts with its protrusion with the roller 26 and lifts up the long end of the lever 12, which in turn raises up the rod 19. The rod 19 moves together with the fork 20 and the clamped spring 22 of the stop 21. The stop 21 moves until it comes into contact with the stopper 27, after what the movement stops. The fork 20, continuing to lift up, in its extreme position, interacts with the device for gripping 2 rod 28j which, in this case, is released and under the action of its own weight falls vertically down onto the stop 21, which occupies a strictly defined position. In this way, dosing occurs. After a while, the brush 19 begins to move downwards. In this case, the fork 20 clears the device 2, which clamps the rod 28. In the process of further lowering, the stop 21 is pressed from the residue 27 and occupies the lowest position. This completes one complete molding cycle, which takes place half a turn around the carousel.
