The invention relates to the construction and can be used in the molding of concrete products.

The purpose of the invention is to simplify the design and reduce the size.

Figure 1 is given the installation, top view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; figure 4-7 - schematic 10 image of the stages of the installation.

An installation for molding concrete products contains a power frame 1, in the upper part of which a press plate 2 is fixed, and in the lower part - a support plate 3, moved in a vertical plane by hydraulic cylinders 4 mounted on a power frame equipped with guides 5 for moving perforated pallets 6 20 With protrusions 7 for fixing them in the slots 8 of the base plate 3 when it is raised. The pallets 6 are provided with a drive for their horizontal movement in the form of a frame I of the pusher being moved along the guides 9 of the frame 10. Under the base plate 3 there is a container 11 for collecting and draining water. The shaping beads 12 are made with shoulders 13 around the perimeter in the upper part, freely supported on the press plate 2, and with channels 14 for venting, located under the press plate 2. The latter is made with a cavity 15 for installing the drive sector 35 of the shutter 16, having the plane coinciding with the working surface of the press plate 2 in the process of pressing. The installation is equipped with a hopper 17 installed on the power frame 1 over the 40 cavity 15 of the press plate, and a vibrator 18 fixed under the supporting frame 3. The forming cavity is formed by the press plate 2, the shaping boards 12 and the pallet 6. To prevent the concrete from falling the mixture outside the cavity, the sector valve 16 is located between the fixed and repeating its configuration washers 19.50

The installation works as follows.

The pusher 10 feeds the pallet 6 for fixing it by means of the projections 7 in the slots 8 of the plate 3. When 55 is created in the hydraulic cylinders 4 of overpressure, the pallet 6 smoothly rises by the support plate 3. In this case, the projections 7 on the pallet are embedded in the slots 8

.

I will fix the pallet on the support plate in a strictly defined position. The lifting of the pallet 6 takes place before the contact with the side walls 12. The latter are pressed against the pallet 6 with their own weight, then the sector shutter 16 opens and the vibrator 18 is turned on, as a result of which the concrete mixture from the bunker 17 fills the forming cavity under its own weight and vibration. At the same time, air is removed from the cavity through the channels 14. After filling and uniform distribution of the concrete mix, sector valve 16 is closed in the cavity and vibrator 18 is turned off. In hydraulic cylinders 4, the required pressure is created in a given mode, as a result of which the support plate 3 is moved upward with respect to the press plate 2 by the forming plate 12.

After the channels 14 are closed in the forming cavity, pressure is created, as a result of which water and air are squeezed out of the concrete mix, and the concrete mix is compressed. Pressed water and air are removed through a pre-laid filter on the perforated surface of the pallet 6, as well as through the slots formed between the sides 12 and the pallet 6, the press plate 2 and the sides 12. The molded and compacted product on the pallet 6 is gently lowered by the base plate 3 by means of pressure relief in the hydraulic cylinders 4 to the guides 5. At the same time, in order to facilitate the separation of the working surface of the press plate 2 from the surface of the compacted product, it is possible to turn on the vibrator 18. Then the pusher 10 is fed to the support plate 3 the following pallet 6, ejecting tray of molded article. Further, the cycle of manufacture of the product is repeated.
