Description

Devices are known for casting metal products by immersing the mold in a bath of liquid metal. Forms in these devices are immersed in the bath vertically, scooping up the liquid metal and taken out in the same direction.

The device of the present invention consists of a series of forms located on the rim of a rotating drum. During the rotation of the latter form, one by one they are immersed in the bath, scooped up the metal and come out of the bath, and, in contrast to the known forms, provided with holes for metal inlet, the mold according to the present invention is made in the form of two halves attached equipped with different devices for closing and opening the molds, in other words, for tightening the tongs and breeding them during the rotation. The molds are immersed in the bath in an open diluted state, in the bath they are closed and in this form are removed from the bath, meeting along the path of the device, opening the molds and knocking out finished products from them, in this case, cast-iron gables.

In FIG. 1 is a general view of the device; FIG. 2 - pincers; FIG. 3 shows the device from above; FIG. 4 is a side view of the device; FIG. 5 is a diagram of a device with a bath; FIG. 6-parts of tools for opening and closing molds.

On the hollow shaft 18, two sleeves 19 are rigidly mounted. Both protruding parts of the latter are covered with a plate 14 fixed with bolts 15 and form a round drum, on the rim of which pliers 5 are located.

The latter (fig. 2) consist of two parts. At the end of each part, half of the 1 forms with the plugs 2 are welded. At the top, each part of the glue plates 3 is provided with bevels 6, 7 with knobs 8. Pliers-forms are mounted on the axis / 3 and equipped with a curved guide 12, along which they move during opening and closing turning around axis 13. Boxes 5 are welded to both halves of the mold 3, constituting the frame, inside which

springs 9, 10 are placed, fixed in the rear walls of the boxes 5 and OTpocTKtr which pass through the holes of the halves of the mites-shapes 3. On the cylindrical surface of the plate 14, a number of holes are drilled (Fig. 6), corresponding to the number of tongs 5; the cams 16c pass through these holes. groove on the inside and heading / ban of the outside. The heading 16a has a groove on its surface, the dimensions of which correspond to the dimensions of the cocks 8 in their reduced state, and is pressed out from the plate 14 by the spring 17. Inside the hollow shaft 18, the axis 22 passes freely on which key 26 is mounted on the key 26 located between the protruding parts of the sleeves 19 and provided with a stop 30 (Fig. 6) for acting on the trigger pin 16. The axis 22 is held from rotation by a stopper 23 fixed to the machine rack 39 by a bolt 24. On both racks 39 (Fig. 1 and 5) machines are firmly fixed to the cranks 31, through the hollow burn horizontal parts of which freely passes the shaft 18; between the protruding vertical parts and the cusps 31, the drum with mites 3 rotates.

 Hoppers 31 are pressed against racks 39 of the machine with inserts 38 and bolts 37 (Figs. 3 and 4). On both internal surfaces of the protruding parts of the moths 31 are fixed one breaker 32 and two stops 33 each, the purpose of which will be described below. The stands of the machine are fixed on the bed / on which the bath 45 (FIG. $) Is located for the liquid metal. Bath lid Supplied with a threshold 46 not holding the slag to the bottom of the vanilla: Metal in the bath is fed by the chute 47. A side chute 35 is attached to the frame 41 to direct the castings into box 36. The anvil 34 is attached to the chute 35. Pipelines 49 and 50 (FIG. 4) serve to supply compressed air and soapy water to the dispenser 48 to spray the molds. Shaft 18 receives rotation from a friction pulley 27 rigidly mounted on it,

rotated by the pressure friction roller 29 from the electric motor 28. The machine operates as follows.

The tongs of the mold 8 in the opened state, during the rotation of the drum, are immersed in the bath 45 with the liquid metal. Upon further rotation, the trigger pin 16 with its head locates against the stop 30, which causes it to move to the center; at the same time, the knives 8 come out of the groove of the heading 1ba, and the springs 9, 10 reduce both parts of the tongs and close the halves / shapes with the iron inside them. Out of the bath, the mites-forms 3 with their bevels 6, 7 are placed on the first pair of stops 55, open slightly and in this position approach the anvil 34. At the moment when the latter is between the two halves of the molds /, the mites are freed from the stops 55 on the bevels 6, 7 and, under the action of the spring 9, 10, are sharply closed and hit the anvil 34, which causes the casting to fall and down the chute 35 falls into the box 36. The trigger pin 16 cannot take hold of the trigger at this moment. 5, since it is under the influence of the breakers 32 pulling it towards the center of the drum.

Further, the tong-shaped tongues are placed with their bevels 6, 7 onto the second pair of stops 55 and open. At this moment, the trigger pin 16 comes off the breakers 32 and, under the action of the spring 17, finds its head 16a on the hammers 8 and keeps the tongs in the opened state; then the cycle repeats.

The subject matter of the invention.
