Description

 The invention relates to the field of manufacturing building materials and can be used in the manufacture of facing bricks and other small-sized building blocks.

 A semi-dry pressing press is known, comprising a rotary table with dies in molds. At the pressing position, the molds are covered from above with a counter-stamp plate (RF patent 2021109, B 28 V 5/06, 1991).

 At the installation, it is impossible to obtain a three-dimensional (relief) pattern of facial faces on adjacent planes.

 A known installation for pressing, containing a rotary platform, the mechanism of rotation of the platform installed in the technological sequence around the circumference of the rotary platform of the mold, dispensers, press, device for extrusion (A. with. The USSR 973370, 28 V 5/06, 1981).

 At the installation, it is impossible to obtain a three-dimensional (relief) pattern of facial faces on adjacent planes.

 The closest in technical essence is the installation for the manufacture of building products, containing a rotary platform, the mechanism of rotation of the platform and installed in the technological sequence around the circumference of the rotary platform of the mold with removable pallets, dispensers, press, a device for extruding and removing the finished product. Force loading of the tooling is carried out using a loading plate (a.c. USSR 1761491, B 28 B 5/06, 1989).

 At the installation, it is impossible to obtain a three-dimensional (relief) pattern of facial faces on adjacent planes.

 The objective of the invention is to obtain a three-dimensional (embossed) pattern of facial faces on adjacent faces by creating additional pressure.

 The technical result is achieved by the fact that in the installation for the manufacture of building products containing a frame, a rotary table, a table rotation mechanism and molds installed in a technological sequence around the circumference of the rotary table, a loading device, a pressing mechanism and an ejector, the mold is provided with a rotary cover with segment emphasis in the upper part and a wedge emphasis in the lower part.

 Known installations for the manufacture of building products, the forms of which are equipped with rotary covers (RF patent 2034707, 28 V 5/10, 1991; a. From the USSR 854721, B 28 V 5/06, 1979).

 In installations it is impossible to obtain a three-dimensional (relief) pattern of facial faces on adjacent planes.

Figure 1 shows a General view of the installation;
figure 2 is a top view;
figure 3 - node a in figure 1, a top view;
figure 4 - section aa in figure 34
figure 5 is a rotary cover, side view.

 Installation for the manufacture of building products contains a frame 1, a rotary table 2, a pressing mechanism 3, an ejector 4 and a loading device 5. Around the circumference of the rotary table 2, molds 6 with a movable punch 7 are installed in the technological sequence. The drive of the pressing mechanism 3, the ejector 4 and The rotary table 2 is made from an electric motor 8 through a belt drive 9 and a gear 10. The gear 10 has three shafts. A cam 12 is mounted on the shaft 11 on one side, interacting via a lever 13 and an ejector 4 with a movable punch 7, and on the other hand, a crank 14 is installed, interacting through the hinge 15 of the Hook with the drum 16. A chain gear 17 is fixed on the drum 16, covering the gear wheel 18, and a freewheel (not shown) mounted on the axis of the rotary table 2. The shaft 19 of the gearbox 10 has the shape of a crankshaft, the neck of which is connected by a rod 20 to the lever 21 of the pressing mechanism 3. The mold 6 is provided with a rotary cover 22 with a segment 23 and wedges m 24 stops. The segment stop 23 interacts with the guide 25, and the wedge stop interacts with the stop 26. At the pressing position, the mold 6 is blocked by the plate 27. In the upper position, the movable punch 7 is held by the latch 28. The working surfaces of the movable punch 7 and the rotary cover 22 are provided with plates 29, 30 with a volumetric pattern.

 The device operates as follows.

Turn on the installation drive. The drive of the rotary table 2 is made in the form of a crank mechanism and provides a discrete rotation of the table 2 at 120 ^o .

 At the loading position, the mold 6 is filled with the mixture from the loading device 5. The rotary table 2 drive is triggered: an empty mold 6 appears at the loading position, the filled mold 6 enters the pressing position. The segment stop 23 interacts with the guide 25, ensuring the closure of the mold 6. The rod 20 through the lever 21 acts on the movable punch 7. The movable punch 7 compresses the mixture to the plate 27. In the upper position, the movable punch 7 is held by the latch 28. The rotary table drive 2 .When the turntable 2 moves, the wedge stop 24 interacts with the stop 26, and the rotary cover 22 rotates on its axis by an acute angle. The mold 6 fits open to the ejection position, the volumetric pattern does not touch the plate 29 of the rotary cover 22. At the ejection position, the lever 13 acts on the movable punch 7 and pushes the finished product to the level of the rotary table 2. The plates 30 of the movable punch 7 act on the volumetric pattern facial face without distortion. The finished product is removed manually. The latch 28 disengages from the movable punch 7. The movable punch 7 is lowered down, closing the rotary cover 22.

 Filling the mold with the mixture, pressing and ejecting the finished product occurs simultaneously.

 The invention allows to obtain a three-dimensional pattern of facial faces on adjacent planes.
