An installation for making ceramic rods consists of a press 1 with a bed 2 fixed on its base, on which a clamping device 3 for a mold 4 is installed, consisting of moving and stationary parts and mounted on a clamping device 3. The connector of the mold 4 coincides with the axis of the press 1 and the press cylinder 5, which is connected to the rod 6 and the guide pins 7.

A mechanism 8 for pushing out the press residue, an actuator 9 for moving the glass and a metering device 10, which is installed between the mechanism 8 for pushing out the press residue and the mold 4, are fixed on the bed 2. The mechanism 8 is pressed on the upper part of the bed 2 by means of the adapter plate 11 and the fastening elements 12 of the hydraulic cylinder 13, which is connected to the rod 14 and the guide pins 15.

A plate 16 is fastened under the press-release mechanism 8 by means of rods 17 fixed on the adapter plate 11. Two catchers 18 and lever 19, which is mounted on the hinge 20 and spring-loaded 21, are located on the plate 16. The rod cleaning mechanism 22 is fixed on the bottom of the plate 16 with bolts 23 and made in the form of a knife 24 with a cheek

25 and the outlet nozzle 26 with a spring-loaded plate 27. The spring 28 presses the plate 27 against the plate 16. The outlet nozzle 26 is located in the opening 29 of the plate 16. The knife 24 and the brush 25 are rotated by the shaft 30 with the drive 31z. for example, an electric motor mounted on the outlet nozzle 26.

An electric motor 31 with a part of the shaft 30 is located on the outer part of the outlet nozzle 26, and the opposite part of the shaft 30 is located in the inner part of the outlet nozzle on which zero 24 and a brush 25 are placed in the end part of the shaft 30 (Fig. 13).

The outlet nozzle 26 has an annular cross section and is made with a slope for better removal of the press residue of the ceramic mixture from the glass after the press residue is destroyed by the knife 24 and the brush 25.

The outlet nozzle 25 is rigidly attached to the plate 27, and its upper part is in the hole of the plate 16. Due to the spring 28, the nozzle 26 has the possibility of vertical movement and, accordingly, the knife 24 with the brush 25 has this possibility (Fig. 3, 4, 13).

The cleaning mechanism of the ejector rod 22 is located under the rod 14 of the mechanism 8 for pushing out the press residue. The drive 9 for moving the cup is made in the form of a shaft 32 with a bracket 33 placed on its upper part, which is spring-loaded. The rotation of the shaft 32 occurs due to the rack and pinion mechanism with the hydraulic cylinder 34. On the bracket 33 of the drive for moving the stack -. A water-cooled case 35 is rigidly mounted, which is made with a spindle 36 having a stop 37 and a turning axis 38, which is spring-loaded 39. A stop bar 40 is mounted on the turning axis 38. The stop 37 is clamped by two oppositely arranged on hinges 41 levers 42, which spring-loaded 43 and mounted on a water-cooled case 35, in which the glass 44 is placed, at equal distances from which two centrirudates of the sleeve 45 are placed.

A glass 44 placed in a water flow: inline housing 35, due to the drive 9 for moving the glass, has a horizontal movement and can be at the positions Clearing the glass 3

on, Lubrication, Dosing and Pressing (Fig. 2). The cooling of the cup 44 is carried out with water supplied through pipes 46 to the body 35, which has two inlet shanks 47 (Figs. 1, 2, 12). Two catchers 18 are installed on the clamping device 3 for the mold 4, the hydraulic cylinder 48, the gate valve 49 is installed on the mold 4, and the nozzle 50 is mounted on the metering device

The installation works in the following way.

In the initial position of the mold 4 is disclosed. Include on the semi-automatic cycle of the installation. Using the hydraulic cylinder 48 of the clamping device 3 for the mold 4, the lever system of the mold 4 is closed and locked by a lever system 4. At this time, the housing 35 YOURWM1 with the feed shanks 47 is located in catchers 18 placed on the plate 16, the rod 14 and the guide pins 15, the press residue pushing mechanism 8 is above the cup 44 and the two centering bushings 45, the lever 19 is retracted and presses the stop bar 40, the gate 36 is open and in contact with the outlet nozzle 26, the stop 37 of the gate, the levers 42 are retracted and the knife 24 and brush 25 are located next to the inner end surface of the glass 44 (Fig. 2, 9, 10). At this moment, at the Clean-up position, the starting shanks 47 are located in catchers 18 and, due to the spring-loaded bracket 33, on which the water-cooled body 35 is placed, are pressed against the upper edge of catchers 18 (FIGS. 4 and 15). There is a fixation of the glass 44 in height.

By the actuator 9 for moving the glass, the water-cooled body 35 with the glass 44 begins to shift in the direction to the position of pressing the mixture. The housing 35 leaves the catchers 18, the gate 36 comes off of the outlet nozzle 26, the stop 37 of the gate is retracted by the levers 42 and the spring 43 to close the cup 44, and the lever 19 continues to press on the stop bar 40 connected to the gate 36, causing the latter to reliably close the bottom of the glass 44.

In the process of moving, the cavity of the cup 44 is covered with a release liner from the nozzle 50 (at lubrication point). Under the dosing unit, the 10th cup 44 interrupts its movement and stops above the upper end of the mold 4, pressing against it due to the interaction of the entry of the Hbix shank 47 with catchers 18

10 and a spring-loaded bracket 33. In the metering device 10, there is a ceramic mass. At the upper side of the cutter of the mold 4 H1-1 of the front end of the glass 44 gate 36

15 is forced to the side, together with the cavity of the cup 44 with the mouth of the mold 4. The press cylinder 5 is turned on, the guides of the needle 7 enter into the centering sleeves 45, and the rod 6 displaces the mass from the cup 44 into the cavity of the presspl-l four.

After holding in the lower position, the rod 6 rises up and then

25, the housing 35 with the cup 44 is moved to the cleaning position of the cup. During the movement to the press-pushing mechanism, the gate 36 is closed with the help of levers 42 and the spring 43, but the ceramic mass partially remains in the glass 44. The water-cooled housing 35 is installed under the stem 14 and the guide pins 15. The gate valve 36 is forcedly retracted and. with the emphasis in the discharge pipe 26

 communicates the cavity of the cup 44 with the inside of the outlet nozzle 26, in which the knife 24 and the brush 25 are placed. The hydraulic cylinder 13 is turned on, the guide pins 15 are inserted into the centering sleeves 45, and the brush 14 is pressed into the cavity of the cup 44 the masses that are destroyed by the knife 24, and the brush is cleaned with the brush 25. The mixture from the glass 44 is removed along the outlet nozzle 26 into the container. Open the mold 4 and remove from it the formed core. Further, the rod manufacturing cycle is repeated.
