The invention relates to foundry, in particular, to designs of automatic casting lines.

The purpose of the invention is to simplify the design, reduce the material consumption and the occupied area.

FIG. 1 shows an automated casting line layout, plan view; in fig. 2 shows section A-A in FIG. one.

The automatic casting line consists of six main sections: branches I of the upper half-form, branches 2 of the lower half-forms, filling and cooling transport 3, extractor 4, steamer forms 5 and form collector 6.

The branch 1 of the upper half-form includes an aggregate 7 for making the upper semi-forms, tilters 8 and 9, the pusher 10 and the latch AND of the vehicle 12 with the section 13 for laying the rods.

Branch 2 of the lower half-molds includes an assembly 14 for making the upper half-forms, tilting devices 8 and 9, a pusher 10 and a latch 11 of a vehicle 12 with a section 13 for laying rods.

Branch 2 of the lower half-molds includes an assembly 14 for the manufacture of the lower half-forms, and a vehicle 15c with a rod laying section 16.

Filling and cooling transport 3, the vehicle 15 of the lower half of the mold and the return box 17 of the lower half-molds are combined into a two-level roller table 18, which has two tilters 19 and 20, also two-dimensional, at the entrance and exit, and each drive has a drive pusher 21 with latch 22 The double roller conveyor has a lower 23 rollers, an upper row of 24 rollers and a frame 25.

At the filling and cooling transport section 3, a two-stage roller conveyor 18 is designed to accommodate the lower half-molds 26 with the half-molds 27 and empty flasks along the section 17 of the empty flasks, and on the vehicle 12, the branches 1 of the upper half-molds, between the unit 7 manufacturing the upper half-shapes and tilter 9, for placing the non-recanted upper half molds 27 on the rollers 28.

The automatic casting line operates in the following sequence.

On the branches x 1 of the upper and 2 lower half-molds, the upper 27 and lower 26 half-molds are made, respectively. Shaping takes place by pressing while simultaneously introducing the model from above, below the auxiliary sealing device so that the molds moved by vehicles 12 and 15 enter areas 13 and 16 in a position convenient for laying the rods, i.e. fret upwards.

After laying and fixing the rods in section 13, the upper mold halves enter tilter 9 and perekantovayut 180 ° in the position of the fret downwards.

The movement of the molds is carried out by means of transport 12 in a pulsed mode. To transfer the half-molds to one shch, energy is supplied to the pressure cavity of the pusher 10 and the retainer 11, which are the power cylinders of the pushing and thrusting action. The motion control system for the half-molds is based on controlling the pressure B of the piston cavity of the retainer so that with equal pressure of the energy carrier in the pusher and the retainer the movement stops, and when the pressure in the retainer drops, it resumes.

At the last position of the branch 1 of the upper half-molds, the half-form is seized by the form assembler 6, lifting and preparing to move to the position of the finished upper half-forms of the branch 2.

The lower half-molds come along the upper russia of the double-deck roller table 18 to the rod stacking section 16 and further to the mold assembly position, where the mold collector 6, after moving from branch 1, lowers the upper half-mold to each lower one.

The forms thus assembled by the next actuation of the pusher 2 and the clamp 22 move to the area of the filling and cooling transport 3.

After pouring the molds with liquid metal, partially cooling and moving to the steaming position, the steaming & amping box 5 grabs each upper half-form, presses the molding mixture with the casting to the lower half-form, removes the pressure of the coma, lifts the flask and moves it to the top 1 upper half-form . Having left with the bifurcated roller table 18 on the upper floor of the lower half-mold 26, the lump and casting are moved, the cooling of the casting in the coma continues and is more efficient than the cooling in the flask of the upper floor of the mold.

At the output of the roller table 18, the lower half-forms alternately enter the tilter 20. The tilter, like the roller table, is two-tier and in its cycle when transferring the flask of the lower half-form from the upper rus, the live rolls to the lower one simultaneously move the free from the flask to the lower half to receive the next lower half-form from the upper rusa In addition, simultaneously with the beginning of the rotation, and with the completion, i.e., with a rotation of 180 °, the lower half-form and discharge of the molding sand with the casting onto the tray leading to the embossing device 4 end.

In section 17, the action of the pusher and the latch in a pulsed mode of the flask are transmitted to the tilter 19, which, after turning by 180 °, sets the flask at the level of the upper shaft of the double roller table 18 in front of the pusher 21 for the latter to feed the latter into. unit making the bottom half-form.

The flask of the upper mold half 27, removed by a steamer of mold 5, is moved and set to ro. ik 28 of the vehicle 12 branches 1 upper half-form before the pusher 10. The subsequent action

the pusher 10 and the retainer 11, each of the cast flasks, is turned by 180 ° to the position for loading the mixture and forming it in the aggregate of the 7-top half-molds.

5 The cycle of movement of the flasks with shaping, assembling, pouring and embossing is repeated.

The invention simplifies the design of the field, reduces the footprint and

Q reduces its material consumption.
