The invention relates to foundry production and can be used in the mass and mass production of castings from various metals and alloys in the machine tool industry and other industries.

The aim of the invention is to increase productivity, simplify construction, reduce mixture consumption and improve working conditions.

FIG. 1 shows the proposed plan, the plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The proposed carousel includes two pozipii 1 and 2 filling-tapping, two positions 3 and 4 seals, a turntable 5, a roller table 6 and 7 of the empty flask and po, langi 8 and 9 of the issuance of the compacted half-form.

At position 1 of the filling - stretch (Fig. 2) is the mechanism 10 for filling the flask of the formo sovochnaya smya reinforced in the upper part of the circumferential frame 11, and the lifting mechanism with the telescopic piston G1 1I1zod 12, on the inside .m rod 13 of which is fixed to the roller table 14 of the change of model sets, and on the outer 15 plate 16 is located, to the lower plane of which cylinders 17 of the exhaust mechanism 12 are attached. On their HJTOKax 18, there is a roller conveyor 19 and stops 20, designed to interact with the pins 21 of the filling frame 22.

At the same diametrically opposite position 2 of the filling-extraction 2, there is a mechanism 23 for filling the flask with molding sand and a mechanism for extracting 24 rolls from angles 25 of changing model sets. On the threads 26 of the stretch mechanism 24, the roll table1 and 27 of the flask change and the stops 28, which cooperate with the filler frame 30, are fixed.

At the position of the seal 3 (Fig. 3) there are press-shaking mechanism 31, a lifting device 32 and a press block 33 with a sprue bowl 34, which are mounted on the frame 35.

At position 4 of the seal (Fig. 3), diametrically opposite to position 3, there is a press-shakeup 1st mecha- 1ShZM 36, 110D15emode device 37 and a press block 38 with sprue bowl 39, which are mounted on the base 40.

The turntable 5 (Fig. 3) consists of a pedestal 41, inside which the column 42 is fastened. Around the column 42, the body 43 rotates with a bracket 44 for mounting four model kits 45-48. Inside the housing 43, a rotary table actuator 49 is installed, made in the form of a piston actuator pivotally coupled by a rod 50 to the rotary table 5, the rotary table 5 being rotatably mounted on an angle of 90 ° and returning to its original position.

Jacket 51 is fixed on case 43 with directions 52, carrying four filling frames 22, 30, 53 and 54 movable with respect to guides 52. Flasks 55-58 are installed on model kits 45-48, and on roller conveyors 6 and 7 mc flasks 59 and 60.

The machine works as follows.

Empty flask 55 on the roller conveyor 6 serves to feed empty flasks to the roller conveyors 19 positions 1. At the same time, position 2 on the roller conveyors 7 and 27 is empty flask 56. The filling frames 22 and 30 are lifted at this time by stops 20 and 28 above the flasks 55 and 56, and the model kits 45 and 46 are lifted by the roller tables 14 and 25 above the brackets 44. This makes it possible to change the model equipment in the mapgin cycle.

At positions 3 and 4 of the seal at this time, pre-shaking occurs in flasks 57 and 58 installed on model kits 47 and 48 with filling frames 53 and 54.

Roller 14 at position 1 rises, removing the empty flask 55 from the roller tables 19 at the same time. Flask 55 is mounted on the model kit 45, and the filling frame 22 is mounted on the flask 55. Formed mixture with the molding mechanism 10 for filling the mold box with molding mixture is fed into the flask 55. As a result of similar operations at position 2. The mechanism 23 for filling the mold with molding sand fills the flask 56. During filling, the rollers 19 and 21 are lowered into the lower position. At positions 3 and 4 of the compaction, shaking occurs with simultaneous pressing.

After filling the flask 55 (item 1) with the roller conveyor 14 mixture, it is allowed to the lower position, install the model kit 45, the flask 55 with the unconsolidated mixture and the filling frame 22 on the brackets 44 of the rotary table 5. Simultaneously (at position 2) the model kit 46 is mounted on the brackets 44 , a flask 56 with an unconsolidated mixture and a filling frame 30. At position 3 of the press-shake compaction, the mechanism 31 is lowered by the lifting device 32 into the lower position, setting the model kit 47, the box 57 with the compacted mixture and the filler hydrochloric frame 53 on the bracket 44 of the turntable 5. At position 4 the sealing mechanisms 36 and 37 establish a set of model 48, 58 to the sealed flask s.mesyu filling frame 54 and the brackets 44 on the turntable 5.

The turntable rotates 90 °, as a result of which the model kit 45, flask 55 with non-compacted molding sand and the filling frame 22 are moved from position 1 to position 3. Model kit 47, flask 57 with compacted mixture and the filling frame 53 do not

moving from position 3 of the seal to position 2 of the filling-out. Model set 46, flask 56, and filler frame 30 are mixed from position 2 of the caps 11 to test the seal position 4. Model set 48, flask 58 with compacted mixture and filling frame 54 alternate from position 4 of the seal to position 1 of the filling-out.

At position 1 of the filling-out of the hole, the model kit 48 is pulled out of the flask 58 by the movement of the roller tables 19 and up, while the roller table 14 rises to the middle position. At the position 2 of the filling-out, the flask 57 is similarly dragged out. At the positions x and 3 the drivers of the device 32 and 37 raise the internal position of the engine 31 and 36 in the upper position, i.e. comes with a sym. of model sets of 45, 46, flashes 55. 56 with a non-compacted mixture and a filling frame 22, 30 with brackets 44 turning-iioi o cTO; ia 5.
