    H 15 The invention relates to foundry, in particular to equipment for centrifugal cast. A device for turning a casting bucket of a centrifugal casting machine containing a mobile carriage, a rod and a turning chute Ci) is known. The closest to the invention to the technical essence and the achieved result is a filling device of a centrifugal machine, including a base, a filling chute with a receiving tray, a hinge support and a lifting mechanism mounted on base 2. A disadvantage of the known devices is the overflow of the metal to be filled and the occurrence of defects castings The aim of the invention is to save the metal and improve the quality of the castings by adjusting the inclination of the pouring chute during the pouring of the metal into the price mold of the engineering machine. The goal is achieved in a center casting machine containing a base, a pouring chute in a receiving tray, a hinge support and a lifting mechanism mounted on the base, the latter is equipped with a console. At the free end of which is an additional hinge support fixed to the pouring end. gutters, and the lifting mechanism is connected to the pouring gutter through a hinge support, the additional hinge support being made in the form of two lateral cylindrical half-arms fixed to the console. FIG. i schematically shows a centrifugal casting machine with a potting device; in fig. 2 primer, general view; FIG. : i - the casting device at the end of the metal pouring into the chill mold; FIG. 4 is a section A-A in FIG. 2; FIG. 5 is a section BB in FIG. 3; FIG. 6 - the pouring end of the filling device; FIG. 7 is a view of B in FIG. FIG. 8 is a centrifugal casting machine with a casting device for casting pipes of small and medium diameter uvieTpoB; FIG. 9 is the same, in the period of the end of metal pouring into the chill, FIG. GO - regulatory scheme; swarm twa. The casting device of a centrifugal casting machine 1 for casting cast iron pipes with a socket 2 having a diameter of, for example, 60 amp -2000 mm is shown in FIG. 1-10. In order to get an idea of the dimensions of the machine 1 and the molded pipes next to the machine, the silhouette of the person 3 is placed (Fig. 1.8). The machine contains a rotary die 4 for casting, placed in crankcase 5 on two pairs of rollers b, at least one of which is driven. The rollers 6 are supported on the fixed frame 7. The cast iron 4 enters the hot metal mold with the help of a casting device 8, which contains a carriage 9, reciprocating along the base 7 so as to be able to insert the channel-beam unit 10 into the most chill mold. the remote end of this chill mold, which is provided with a bell 11. The pouring device 8 is fed, in turn, from a rotary casting bucket 12 having a constant axis of rotation. In the elongation of the crankcase 5, on the other side of the device 8, is located; an exhaust mechanism 13 moving in the track. 14, along which the two support carriages 15, 16 and the exhaust carriage 17, as well as the means G8, move. The node 10 contains a support beam 19 with a large moment of inertia and a composite channel 20. The beam 19 is fixed with its input end on the trolley 9 and is placed cantilever in the direction of the centrifugal-casting machine. The free end of this beam is provided with two horizontal lateral cylindrical protrusions 21. Channel 20 is formed by a cradle 22, on which is placed a drainage chute 23, equipped at the input end with a funnel, 24, and at the output end a drain toe 25 and Consisting of a series of consecutively placed segments. Xfejiob 23 can be monolithic. The cradle 22 is located on the drain toe 25. Two cylindrical ones are located slightly higher than it. cuspins 26, mating respectively with the top of the projections 21 of the beam 19 and resting on these protrusions. Directly behind the carriage 9, towards the exit end, is placed an earring 27 protruding under the cradle. A double-acting power cylinder 28 is fixed on this shackle 27, which is fastened to the front of the trolley 9 at the same time. The composite channel 20 is pivotally / rotatable between its downstream end between the lower, almost horizontal position shown in FIG. 1 and 2, and the upper position, inclined at an angle relative to the horizontal (Fig. 3). These extreme positions correspond to a state of complete retraction and a state of full extension of the power cylinder 28.
    The assembly 10 comprises a device for controlling the flow rate, shown schematically in FIG. 10. This device contains a cast iron level sensor 30 located near the drain plug 25 and associated with a two-position spool valve 31 controlling the power supply of the pressure cylinder 28 of the power cylinder. The sensor 30 is an inductor connected by wires 32 with a control electromagnet 33, acting on a spool valve 31, by overcoming the action of the return spring 34. The control electromagnet 33 is provided with a chronometer 35,
    The operation of the device is as follows.
    Before casting, the carriage 9 moves until the drain sock 25 of the channel 20 is inside the socket 11 of the mold 4, which is driven into rotation around its longitudinal axis. It is at this moment that the molten iron is poured out of the casting bucket 12 and begins to fill the chill mold 4. The cart 9 then begins to move in the opposite direction so that the drain sock 25 passes along the entire length of the kokky to the exit from the opposite bell of the chill mold.
    During this Backward Movement; Nom direction, if necessary, you can change the angle of the kangsha using the power cylinder 28 to change the flow rate of the cast iron poured out of the drain nose 25 at any point of the chill mold. .

    2if
    This method of temporarily changing the position of the casting means became possible due to the presence of a funnel 24, which plays to a certain extent the role of a variable capacity buffer for each casting ladle 12, which supplies cast iron with a constant flow rate and the chute 23 itself.
    When the drain toe of channel 20
    0 reaches the point of its stroke, located at the flat end of the chill mold 4, the pouring of iron from the bucket 12 into the funnel 24 stops. Then (and again without changing the speed of movement 5 of the carriage 9) the power cylinder is again actuated so as to gradually increase the inclination of the node 10 and feed a constant amount of iron into the metal 4. Therefore, the magnitude of the flow rate on the drain sock 25 remains constant until this sock comes out of the chill mold.
    During this period of casting, unit 10 rotates on two projections of beam 19. Increasing the inclination of channel 20 compensates for the lack of power at the inlet, so that the smooth end of the rotating chill mold accepts the same portions of liquid iron of the same thickness as before the termination of Feeding. As a result of this, the pipe is cast and has an even end of the same thickness with the same inclination of the coilsj as the rest of it and the quality
    5 of this pipe is the same to the flat end ..
    This increase in inclination can be made automatically by the means shown in FIG. ten,
    0 which is triggered after the cessation of the supply of the funnel 24, as soon as the level of cast iron is near. drain tip 25 decreases.
