    A system for producing foundry molds providing a device for filling empty mold boxes with mold forming material at a filling station includes a first rotary shifting device and a second rotary shifting device located on opposite sides of the filling station. The first shifting device operates to shift pattern devices from the filling station to a first shifting station while simultaneously moving another pattern device from the first shifting station into position at the filling station. Likewise, the second shifting device moves mold halves from the filling station to a second shifting station while simultaneously moving an empty mold box from the second shifting station to the filling station. The pattern devices are moved to and from the first shifting station by a first conveyor device and the empty mold boxes and the mold halves are moved to and from the second shifting station by a second conveyor device which extends generally parallel to the first conveyor device. A third parallel conveyor device transports assembled filled mold boxes and pattern devices from the filling station to a single-station mold forming unit.

Half of the table 18 is connected through another control exhibiting a valve (not shown) with another vacuum pipe 55- The bearing surfaces 20 and 14 are preferably made as a polished flat surface without grooves. The transport device 5b (see Fig. 1-4) consists of a working cylinder 57} supported via a console 58 to the bottom 59, a carriage 60, which is connected both to the working cylinder 57 and through a connecting rod 61 to a carriage b2. Cart 60 can move on rollers 63 along rails 64 from position b5 to position 66. Cart 60 consists of a middle part 67 with rollers 63 mounted on it and working cylinders 68 rigidly connected on both sides. Rods b9 of working cylinders 68 can engage with taper holes 70 of the clutch plates 71 of the model kits 72 and 73 and hold them. By switching the working cylinders 68, the rods b9 can be returned back to position 74, in which the rods b9 release the model kits 72 .and 73- Working cylinders 75 and 76 of the trolley 62 cootBeTCTcreate the execution of the working cylinders 68 of the trolley 60. Working cylinders 77 and 78 can hold the model kits, if they are in positions 79 and 80, on the roller table 7. The installation is operated as follows. On the vehicle 5, the position 82 is set at the position 81. The clamping devices 12 and 11 switch and engage the position 82 and, accordingly, half of the mold 83. The displacement device 2 lifts the flask 82 from the vehicle 5 to the position 84 or half of the mold 83 from the model kit 13 to the position 85. The cylinder 47 switches simultaneously. The rod 48 moves to the position 86, and the push rod 53 of the weight of the onv jets position 87 to position 88. After passing the partial path by the transporting device 2, the clamping device 32 switches, a pair of 3 clamping levers is moved from position 89 to position 90 and is released by the cam 30 half 18 one hundred Then the drive 16 drives the movement of the moving device 2, which rotates halfway in the direction of the arrow 91 so that half of the molded form 83 is above the vehicle 5, and the flask 82- above the turntable With the actuator 92, the turntable 15 is rotated half a turn in the direction arrows 93- Model kit 13 gets into position 9 model kit 21 - at position 95 Device 2 switches to medium outflow and lowers the half 82 of the molded form to the vehicle 5 and the box 82 to the model kit 21. Cylinder 47 also switches its rod 48 moves to position 50, and the push rod 53 rises from position 88 to position 87, after which the clutch 9b is engaged by switching the cylinder 97 and engaging the rod 98 in engagement with the holes 99 of the clutch plate 71. By switching the vacuum pipe 54 of the table half 19 to atmospheric pressure, the suction effect of the support surface 20 exerted on the model set 21 is terminated. The clamping devices 12 and 11 switch and release the flask 82 and, accordingly, half of the mold die 83. The lifting device of the table half 19, which is made identical to the lifting device 24 of the table half 18, switches and lifts the roller table 19 half of the table so that they lift the model kit 21 from the support surface 20. The clamping device 32 switches so that a pair of 34 clamping levers moves out position 90 to position 89 and holds the cam 31 of the table half 19 at position 95 By switching to compressed air, the movement device 2 rises. From the device 8, the molding material is poured into the flask 82. While the empty flasks and the half of the cast form move further on the vehicle 5 by one division in the direction of the arrows 100 and 101, the plunger 37 is driven. The gear motor 39 is rotated by half rotation from position 102 to position 1031 is shifted by model kit 21 in the direction 104 of the arrow through the roller 105 to the molding unit 1. After the molding material is compacted, the gear motor 39 is again driven and moves the drive crank 40 from position 103 to position 102 and thus the model kit 21. with the half of the molded form on it returns back to position 95 The lifting device of the half of the table 19 switches and lowers the model kit 21 with the half of the molded shape to the bearing surface 20. By switching, moving device 2 is lowered to the position shown in fig. 2, Vacuum line 54 is switched to vacuum. Clutch 9b is disengaged. Thus, the manufacturing process for manufacturing half of the mold is completed. If the required number of mold halves is made from the model kits 13 and 21 in operation, the model kits are replaced as follows. If model kit 21 is turned to position 94, slave cylinder 75 is switched and its rod engages with the clutch plate of model kit. Vacuum line 54 switches to atmospheric pressure. The lifting device of the table half 19 is raised by switching and lifts the model kit 21 from the support surface 20. The working cylinders 106 and 107 simultaneously switch and release the model kit 108 and 109. Then the working cylinder 57 switches and moves the cart 60 from position 65 to position 66 and cart 62 from position 110 to position 111. As a result, this model set 21 moves from half of table 19, to position 79, model set 108 to half of table 19, and model set 109 to position 112. Worker
    the cylinder 106 or 77 switches and holds the model kit 108 or 21 in position 112 or 79- The lifting device of the table half 19 switches and lowers the model kit 108 to the bearing surface 20. The working cylinders 68 or 75 of the carriage 60 or 62 switch, the clutch rods 69 move to position Then, the working cylinder 57 switches and shifts the carriage 60 from position 66 to position 65 or carriage b2 from position 111 to position 110. In the manufacture of the further half of the mold, the process is repeated.
    The proposed installation allows, using a molding unit with one technological position and two model sets, to alternately produce half molds in the form of upper and lower parts, i.e. whole casting molds. The installation allows you to check each of the model sets after the manufacture of the appropriate form during the stopping of the turntable, to impose external refrigerators. Replacing model kits that have been removed from work with other model kits is carried out without difficulty.
