- -Invention relates to foundry, in particular to devices for knocking out stack molds.

A known installation for knocking out predominantly rods of castings, comprising a synchronized-drive carousel table, knock-out devices, an overhead conveyor for casting, ring guides, and casting-receiving devices podvizhennye to the carousel table 1.

The disadvantage of this installation is that it does not allow to knock out castings obtained in stack molds on the suspension x of the conveyor.

The purpose of the invention is to provide for knocking out forms on conveyor hangers. This is achieved by the fact that the installation is equipped with a bunker installed above the knockout grill and spaced in it at an angle to each other in the direction of the bunker inlet receiving areas with failed windows, and the means for receiving castings are made in the form of fork-shaped levers with a rotational drive in a vertical plane, installed hinged on the frame under the failed windows.

FIG. 1 shows the proposed installation; in fig. 2 - the same plan view; in fig. 3 is the same section in section A-A in FIG. in fig. 4 - lower section.

The installation consists of an overhead conveyor with an overflow section 1, a coupling 2 with suspensions 3, on which bezopochnye molds 4 are installed, a bunker 5, unloading platforms 6 with failing windows 7 and stops 8, laying handlers 9 with pneumatic cylinders 10, frame, 11, knock out grating 12 with pneumatic vibrating valve 13 and shock absorbers 14, belt conveyor 15 and sliding conveyor 16..

Claims (1)

In the initial position, the elements of the installation are shown in FIG. 1, i.e., the levers 9 are located under the unloading platforms 6 parallel to the failing windows 7 and are hingedly mounted on the frame 11. The suspensions 3 with casting molds 4, illuminated on the coupling 2, are located on the lower section 1 of the overhead conveyor above the bunker 5, and knocked out a lattice 12, which is made in the form of strips with certain intervals and provides the possibility of passing the beaters of stackers 9 through the grille 12, is installed above the hopper 5 on the common frame 11 on rubber shock absorbers 14. The pneumatic vibrator 13 is located on the frame 17 lattice 12. The lower section 1 consists of a route of the conveyor 18, fixed and movable sections 19 and 20 of the track, carriage couplings 2, pushers 21 and guides 22 mounted on a common metalwork 23. The unit operates as follows; in this way. The lowering section 1 of the overhead conveyor lowers the coupling 2 with the year hangers 3, on which the bezopochnye casting molds 4 are installed in piles, into the bunker 5 (see Fig. 1). The suspensions 3 with bezopochnye casting molds 4 slides along the unloading platforms 6 up to the stop 8, are above the failing windows 7. The hangers 3 hang on the unloading platforms 6, and the bezopochnye casting forms 4, under the action of their own weight, slide off the suspensions of 3 g through the failed windows 7 fall on stacking levers 9. With the help of pneumatic cylinders 10, the levers 9, turning around the hinges, alternately shift the bezopochny casting molds 4 to the embossing grid 12, where the casting of the castings is reliable with the help of a pneumatic vibrator pa standpipe section 13. The overhead conveyor 1 raises osvobodivshies from 4 forms suspension 3, and the conveyor is moved to the next position for a new load. The descent section 1 operates as follows. The coupling 2 moves along the conveyor 18 track of the stationary track section 19 by means of pushers 21 mounted on the conveyor chain. In the knockout zone of the coupling enters the movable section 20 of the path. The movable section of the track, connected by cables 24 to winch 25, is lowered with coupling 2 along guide rails 22 into hopper 5. The ground that spills through the embossing grid 12 is removed by belt conveyor 15, and the walking conveyor 16 is cast from the knock out grid by means of movable frame, made in the form of forks. After the castings are removed from the knock out grill, the stacking levers return to their original position. The process then repeats. An apparatus for knocking out forms, preferably stacking, containing overhead conveyor arranged one above the other, frame with knockout grille, devices for receiving castings and a conveyor for a burned mixture, characterized in that, in order to provide for knockout of forms on conveyor hangers, it is provided with above the knock-out grid of the bunker and placed at it at an angle to each other in the direction of the entrance hole of the bunker receiving areas with failed windows, and devices for receiving castings are made They are not in the form of fork-shaped levers with a drive to turn them in a vertical plane, which are installed hingedly on the frame under the failing windows.
