    The invention relates to a foundry, in particular, to machines for the manufacture of flaskless molds. A known pressless-pressing mold containing a drive consisting of a cylinder movable in the axial direction, which is tied to one pin through the pinch rod and rigidly, and the rod is attached to the second pin tl3. However, this machine requires special measures to control the movement of the cylinder and, in addition, it is necessary to use moving pipes or hoses for the hydraulic system. The closest to the invention in terms of technical capacity and effect achieved is a device for producing horizontal bar-padded bezopochnye forms of pressing, containing a frame on which the dispensing device is located, a sand-blown head connected to a source of compressed air, a pressing chamber with a pressing plate rigidly connected with a piston actuator piston drive and a backpressure plate through an intermediate element and a system parallel to the motion of the piston actuator; reteni - increase reliability and ease of operation. This goal is achieved by the fact that in a device for making horizontal stackable molds by pressing, comprising a bed on which a dosing device is placed, a sandblasting head connected to a source of compressed air, a pressing chamber with a pressing plate rigidly connected to a piston drive rod of pressing and The back pressure plate associated with the piston drive shaft of the counter pressure through the intermediate element and the system parallel to the course of the piston drive draws pushing rods, the rod and and the pistons of the drives of the pressing and counterpressor plates are rigidly interconnected and intermediate. element is placed on the bed, the pressing plate is mounted on the movable pressing actuator cylinder, and the transverse beam connecting the backpressure plate and the system parallel to the course of the piston drive pulling and pushing rods are mounted on the outer side surface of the movable counterpressure piston drive, and the channels for supplying the working fluid, they are made in an intermediate element and stationary rods and pistons of press and backpressure drives. Figure 1 shows the proposed device, side view} in figure 2 hydraulic drive device. The device comprises a conventional extrusion chamber 1 with a crush 2 having an opening through which sand or other molding material can be introduced from the feed hopper 3. The latter is connected via pipe to a valve (not shown) to a compressed air reservoir 4. Chamber 1 is closed at the ends by pressing plate 5 and counter pressure plate 6, on the inner or front surfaces of which half-molds (not shown) must be fixed to form corresponding casting cavities in the ends of the mold formed by sand grinding. After extrusion of said part of the casting mold, the backpressure plate 6 can be doubled from chamber 1 and turned upwards in the hinge 7, after which the pressing plate 5 can be informed by an additional movement to the left to transfer the finished mold to the guide track 8 where it is added to form 9 composed of the respective molding parts. After parts of the device have returned to their original position (FIG. 1), the process can be repeated in order to fabricate and close the next part of the mold. The displacement of the press plate 5 is carried out using a hydraulic drive unit 10 comprising a cylinder t1 (FIG. 2), to which the press plate 5 is rigidly attached, and a piston element comprising a piston head 12 and a piston rod 13, which is tightly fixed through the inside face the wall 14 of the cylinder 11 and is fixed on the stationary block 15. The piston element separates the cylinder cavity into the outer end chamber 16 and the inner annular chamber 17, which through channels 18 and 19, made in the piston element and block

    15, communicates with external pipelines 20 for injecting and discharging the working fluid. The maximum pressure on the press plate 5 for pressing sand in the chamber 1 and for transporting the mold. 9 The addition field of the newly made part of the mold is created by supplying the working fluid to the end chamber 16 and freeing it out of the annular chamber 17. If necessary, the liquid displaced from the annular chamber may be fed into the end chamber in order to impart an accelerated motion to the press plate 5. In the case where the cross section area of the annular chamber is half the size of the cross section area of the end face ry, the press plate may (at a given pump capacity) to have a velocity equal to the velocity obtained when moving in the opposite direction.

    and is carried out by supplying the working fluid to the annular chamber 17 and freeing it out of the end chamber 16.
    The backpressure plate 6 comprises a similar drive unit 21 with a cylinder 22, a piston head 23, a piston rod 24, which is also fixed on the block 15, an internal
    the wall of the cylinder 25, the outer end chamber 26, the inner annular chamber 27 and the channels 28 and 29 communicating with the outer conduits 30. In this case also moving
    the element is a cylinder 22, which is connected to the counter-pressure plate 6 by means of a transverse element (cross member) 31 fixed on the cylinder 11 at its inner ring,
    moreover, the transverse element 31 is attached by means of parallel pull and push rods 32 to the frame 33 supporting the plate 6 in the hinge 7.
