    The invention relates to foundry, in particular to devices for pouring molds.
    A device for pouring "metal containing a bucket with refractory lining, and this bucket is mounted in a cassette on a platform that moves along the conveyor ί 1 ^ · ιθ
    The disadvantage of this device is the significant time required to replace the oat.
    The purpose of the invention is to reduce the time taken to replace the bucket. fifteen
    This goal is achieved in that the device for pouring metal into forks mounted on the conveyor, including a platform mounted * 0 on rails with the possibility of reciprocating movement parallel to the conveyor, and a cassette with a drive for installing a bucket, is equipped with an additional cassette, and the cassettes are installed with the possibility of reversal in a vertical plane around an axis passing through the nose of the bucket and perpendicular to the direction of the conveyor. .
    In FIG. 1 shows a device, side view; in FIG. 2 - the same, top view; in FIG. 3 - same, right view.
    The filling device contains a rail platform 1, moving along the rails 2 under the action of the hydraulic plunger 3 at a distance A. On the platform there is a vertical rack 4, in which bearings (not shown) are mounted, designed for difficult working conditions. Two mirror-mounted cartridges 5 are attached to the rack, which can be rotated upward using hydraulic plungers 6 located between the platform and the crank arm 7, which in turn is connected to the cartridge 5 by an intermediate shaft 8, mounted in the bearings of the rack 4. There are devices in the cartridges, for example, hooks 9, for securing buckets 10. In FIG. 1 and 2, only one bucket 10 is shown mounted in the cartridge 5. The other bucket is removed to demonstrate the replacement of buckets.
    In FIG. 2 shows in more detail line 11 with molds 12 exiting a molding machine (not shown). The bucket drain socks 13 have such a shape that the metal stream enters the mold feeders 14 during the pouring process so that the position of the metal stream at different angles of inclination of the bucket 10 does not change. On the buckets there is a lifting bracket 15, by means of which they can be easily removed from the cassettes with the help of an auto-loader for filling with liquid metal.
    'As a result of this arrangement, the distance between the drain socks 13 of both buckets 10 is very small, even if the buckets 10 have a relatively large volume. This arrangement also provides a quick transition from pouring metal from one bucket located in the cassette 5 to pouring from another bucket, since the platform can be quickly moved to a distance A corresponding to the distance between the drain socks using a hydraulic plunger 3. 20
    When the device is operating, the bucket 10 filled with liquid metal is mounted in one cassette, while the hydraulic plunger 3 is moved to the experimental position corresponding to the filling position shown in FIG. 2 dash-dotted line BB. Filling starts when the plunger 6, located in this part of the platform, tilts the bucket 10 so that the metal begins to flow through the drain sock 13 into the mold feeder 14. The consumption of metal during the pouring process is regulated by a hydraulic plunger 6. It is desirable that the bucket 10 should have a shape giving in cross section a sector of the circle, as a result of which when the bucket is tilted by one gram. the same portion of metal will flow out of it, which facilitates the adjustment of the pouring process until the bucket is completely empty. Filling stops when the bucket moves to its original position under the influence of the hydraulic plunger 6. During pouring of metal from the bucket installed on the right side of the platform 45, another bucket filled with metal is installed on its left side on the opposite cassette (in FIG. 1 and 2 on the left). The transition from pouring from one bucket to pouring from another bucket is carried out by ’moving the platform 1 using the plunger 3 to a distance A corresponding to the distance between the drain socks of the buckets. The platform is moved at the same time as the 55 automatic feed molding machine of a new shape.
    In one of the filling devices, the distance A is 400 mm and the buckets can be replaced in 3 seconds. In this case, a hydraulic knee-lever mechanism (not shown) is used as a tilt mechanism, providing a quick adjustable tilt of 1-5 ^, and a screw jack (not shown), driven by a thyristor-controlled DC motor. A knee-lever mechanism is used to start and end pouring, while a screw jack is used to continuously tilt the bucket; what is needed to control the pouring speed.
    In the proposed filling device, the hydraulic plunger 3 is designed to provide reciprocating movement of the platform at a distance A corresponding to the distance between the axes of the drain socks of the buckets. However, the hydraulic plunger can be replaced with any other drive type.
    In the proposed device axis. the drain socks are parallel to one another, and the rotary shafts 8 are also parallel to one another and are located horizontally. If it is necessary to further reduce the distance between the drain socks, the rotary shafts 8 can be tilted one relative to the other, and therefore, the distance between them can be reduced.

    The invention relates to foundry production, in particular, to die casting devices. A device is known for shaving metal containing a ladle with a refractory lining, and this ladle is fixed in a cassette on a platform that moves along the conveyor 111. A disadvantage of this device is the considerable time required for the replacement of the ram. The purpose of the invention is to reduce the time required to replace the bucket. The goal is achieved by the fact that the device for metal stitching in the formulas installed on the conveyor, including a platform installed on the guides with reciprocating movement parallel to the conveyor, and a motorized cartridge for mounting the bucket, provided with an additional cassette, and the cassettes are installed possibility of turning in the vertical plane around the axis passing through the toe of the bucket and perpendicular to the direction of the conveyor. FIG. 1 shows a side view of the device; in fig. 2 - the same, top view; in fig. 3 - the same, right view. The casting device comprises a rail platform 1 moving along rails 2 under the action of a hydraulic plunger 3 at distance A. On the platform there is a vertical support 4 in which bearings (not shown) are fixed, designed for harsh working conditions. Two mirror-mounted cassettes 5 are attached to the rack, which can be turned upward by means of hydraulic plungers 6 located between the platform and the crank arm 7, which in turn is connected to the cassette 5 by an intermediate v-8 fixed in the bearings of the rack 4. There are devices in the cassettes, for example, hooks 9, for securing the buckets 10. In FIG. 1 and 2, only one bucket 10 is shown mounted in the cassette 5. The other bucket is removed to demonstrate replacement of the buckets. FIG. Figure 2 shows in more detail line 11 with molds 12 exiting the molding machine (not shown). Drain socks 13 of the buckets have a so-called shape, in which the metal stream enters the feeders of the 14 molds during the pouring process so that the position of the metal jet at different angles of inclination of the bucket 10 does not change. On the buckets there is a lifting bracket 15, by means of which they can be easily removed from the cassettes using a forklift for filling with liquid metal. As a result of this arrangement i, the distance between the drain socks 13 of both buckets 10 is very small, even if the buckets 10 have a relatively large volume. This arrangement also provides a quick transition from pouring metal from one bucket, located in cassette 5, to a clip from another bucket, since the platform can be quickly moved to the distance A, corresponding to the distance between the drain socks using the hydraulic plunger 3. During operation the device is filled with liquid metal bucket 10 is installed in a single cassette, while the hydraulic plunger 3 is moved to the experimental position corresponding to the fill position shown in FIG. 2, a dash-dotted line B-B The fill starts when the plunger 6 located in this part of the platform tilts the bucket 10 in such a way that the metal begins to flow through the drain sock 13 into the feeder 14 of the mold. Ra. the course of the metal in the process of pouring is regulated by a hydraulic plunger 6. It is desirable that the bucket 10 has the shape of a circular sector in cross section, resulting in one bucket when tilting the bucket. from it you will flow the same amount of metal, which makes it easy to adjust the process of pouring until the ladle is completely empty. The pouring stops when the bucket moves to its original position under the action of the hydraulic plunger 6. During pouring the metal from the bucket installed in the right side of the platform, another bucket filled with metal is installed on its opposite side on the opposite cartridge (in Fig. 1 and 2 left). The transition from pouring from one bucket to pouring from another bucket is accomplished by moving platform 1 by means of plunger 3 to distance A, corresponding to the distance between the toes of the buckets. The movement of the platform is carried out simultaneously with the feeding of an automatic molding machine of a new form. in one of the casting devices, the distance A is equal to 400 mm and the replacement of oats can be made in 3 seconds. In this case, a hydraulic knee-lever mechanism (not pointed) is used as a tilting mechanism, providing a quick adjustable tilt of 1-5, and a screw jack (not shown), driven by a DC motor with thyristor control. A knee-lever mechanism is used to start and end pouring, while a screw jack is used to continuously tilt the bucket necessary to control the pouring speed. In the proposed filling device, the hydraulic plunger 3 is designed to provide a returnable movement of the platform to the distance A, corresponding to the distance between the axes of the drain socks of the bucket. However, the hydraulic plunger can be replaced by any other type of actuator .. In the proposed device, the axis of the drain socks are parallel to one another, and the rotary shafts 8 are also parallel to one another and are horizontal. If it is necessary to further reduce the distance between the drain points, the rotary shafts 8 can be inclined relative to each other and, therefore, the distance between them can be reduced. Apparatus of the Invention A device for pouring metal into molds mounted on a conveyor, including a platform mounted on a cadi guideline with the possibility of reciprocating movement parallel to the conveyor, and a drive cartridge for installing a bucket, characterized in that, in order to shorten the time for replacing the bucket, it is equipped with an additional cassette, and the cassettes are installed with the possibility of rotation in a vertical plane around an axis passing through the toe of the bucket and perpendicular to the direction of the conveyor.
