    The machine has a casting ladle mounted rotatably on a movable support member which conveys the ladle between a filling station and at least one casting station. The movable member carries a motorized rotary disc cam cooperating with a cam-follower which controls rotations of the ladle. The cam profile includes a larger sector of increasing radius to cause a pouring rotation of the ladle at the casting station and a smaller sector of decreasing radius to cause a return rotation of the ladle to the upright position after casting. The cam has, between the two sections, a profile portion which is re-entrant towards the axis of rotation of the cam and in which the cam-follower is engageable selectively to cause a sharp rotation of the ladle from the upright position to an inverted position, so as to release the skin or crust of solidified metal from the inside of the ladle when the latter is at a cleaning station. Control means are provided for avoiding engagement of the cam-follower in the re-entrant portion at least when the ladle is in the casting station, and for disengaging the cam-follower from the re-entrant portion after the inversion of the ladle.

    The taller shaft 12, on which the lever 13 is fixed, carries the bucket 4. The j bucket rotates around the toe 14, since the toe 14 is on the axis of the shaft 12. The endless chain 15 connects the driven sprocket 16 fixed on the shaft 12 and the sprocket 17 mounted on the lower end of the shaft 9. Inside the shaft 9 there is a movable rod 18 with a toothed rack 19 at the lower end which engages with P1sterney fixed to the shaft bearing the sprocket 17. At the lower end of the shaft 9 there is also attached a bracket 20 with a probe 21 to determine metal level. The lower end of the probe 21 is located below the upper edge of the bucket 4.
    At the upper end of the shaft 9, a control means 22 is installed, comprising an electric motor 23 with a gearbox having an output shaft 24 on which a disk cam 25 is fixed (Figures 4-7). The gearbox motor 23 rotates the cam 25 in the direction of the arrow C (FIG. 4). At the upper end of the stem 18 there is a T-shaped head 26 (Figures 1 and 3), on the branch of which there is a roller 27 interacting with the cam 25. The cam 25 profile has a section 28 with gradually increasing: from radius from point-29 to point 30 and a section 31 with a gradually decreasing radius from point 30 to point 32. Between sections 28 and 31 of the cam profile, there is a radial slot 33. At the upper end of the shaft 9 there is a double action hydraulic cylinder 34, the stem 35 of which is connected to a T-shaped head 26. The stem moves in hole 36 of head 26 and has restrictive shoulders 37 and flange 38. A spiral spring 39 is placed between the flange 38 and HEAD 26.
    The roller 27 is in contact with the cam 25 due to the weight of the rod 18 and the head 26 and under the action of the force of compression of the spring 39.
    The device works as follows.
    In the initial position (FIGS. 4 and 3, solid lines), the roller 27 driven by the cam 25 is above the slit 33, but it cannot fall into it due to the engagement with the head 26 of the collar 37 of the rod 35 pushed upwards. The vertical position of the rod such that the bucket 4 is located in a vertical position (figure 1). The bucket is filled with liquid metal and is located at one of the different positions on the mold 6 (Fig. 2). The motor 23 is turned on and the cam 23 rotates in the direction of the arrow C. The cam portion 28 engages the roller 27 at point 29, causes the bushing 18 to rise and transmit the rotation of the bucket 4 in the direction of the arrow D (Fig. 4). The body of the bucket 4 rises oppositely to the drain nose 14 and the metal is poured along the nose 14 into the mold 6. The change in the radius of the cam portion is determined experimentally so that during casting the metal flow rate is constant or variable as required.
    At the end of the casting, the roller 27 is engaged with the point 30 of the section 28 of the cam 25 and the bucket 4 is maximally inclined (figure 5). The metal is poured, but a crust or crust remains on the internal surfaces of the bucket.
    The cam continues to rotate in the direction of the arrow C and the roller 27 contacts the portion 31, while the head 26 with the stem 18 is lowered. The bucket then returns to its initial position (Fig. 4). During this time, the lever 2 rotates to transfer the bucket 4 from the casting position to the cleaning position 40 (FIG. 2). In this position, the hydraulic cylinder 34 lowers the rod 35 with the head 26 to the lower position a (FIG. 3, dotted line), and the roller 27 lowers into slot 33. This will cause the bucket 4 to rotate in the direction of the arrow E, i.e. to the final position (FIG. 6).
    The stem is lowered very quickly, in the order of 1.5 s, and a rise of 15 seconds. Such a quick lowering of the stem leads to complete separation of the peel or

    Ssh, which falls into the receiver. Then the hydraulic cylinder 34 raises the rod 331 and the rod 18 with the head 26 in their original position. The lever 2 is rotated, transferring the node 3 to the loading position. The unit 3 is lowered when the engine 8 is turned on until the probe 21 contacts the metal in the furnace 3 (Fig. 7). Then the cylinder 34 lowers the head 26 to an intermediate position (FIG. 3, dotted line). In this position, the bucket 4 is tilted back and its edge is below the drain tip. Through hole 41 metal
    5 fills the bucket 4. The hydraulic cylinder 34 raises the rod 35 to the initial position (FIG. 3, solid lines) and the entire system returns to its original position (FIG. 3 and 4). At the same time, node 3 is lifted and transferred by lever 2 to another casting position. The proposed option is convenient for producing large castings; for small sizes of castings, another option of using the device is convenient (Figures 8-13). The cam 25 also has a section 28 with an increased radius of increasing and a section 31 with a decreasing radius and a slot 33 of arcuate spiral shape. The slot 33 also ends near the axis of rotation of the cam 25. When the roller 27 is located near the entrance to the slot 33 (Fig. 9), the working conditions correspond to the positions in Fig. 4, i.e. the bucket 4 is in a vertical position at the beginning or at the end of the casting cycle.
    Motor 23 is a reversible DC motor, which upon termination of the spill.

    ki, when the bucket is at one of the cleaning positions 40, begins to rotate in the opposite direction, the cam 25 rotates in the direction of arrow G and at high speed compared to its speed when rotating in the direction of arrow C.
    Then the roller 27 enters the spiral slot and moves to the cam axis (Fig. 12), causing the bucket 4 to roll over. This operation takes about 1.5 seconds to remove the nasty from the bucket. The gearbox motor 23 is turned on and the cam rotates and the direction of the arrow C. The rotation stops when the roller 27 is set in an intermediate position along the length of the slot 33, with the bucket 4 tilting back for loading (Fig. 13). Liquid metal loading

    from furnace 5 is carried out as described. After loading and bucket motor 23 is turned on to rotate cam 25 in the normal direction along arrow C to the initial position and the cycle repeats.
    An embodiment of the device (Figures 8-13) provides a faster casting cycle.
