Description

The invention relates to a foundry and can be used to remove a piece of casting from a mold and to separate castings from gating systems.

The purpose of the invention is to automate the process of separating castings from gating systems and to provide reconfiguration when the shape of a piece of castings is changed by fixing the tong clamp.

Fig. 1 shows an installation for separating castings from gating systems; FIG. 2 is view A of FIG. on fig.Z - section BB in figure 1; on Fig.4 is a section bb In Fig.1; figure 5 - section GG on figo1; figure 6 - section dd in figure 4; figure 7 - section EE in figure 5.

The apparatus for separating castings from gating systems comprises a frame

1with a trolley mounted on it

2 with a drive 3 fastened to the frame 1. Under the frame there are embossing grill 4 and a cooling conveyor 5. On the knock out grill A, there are fasteners 6, made in the form of vertical posts 7 mounted for movement in the holes on the beam 8. The stops 6 can be attached to special brackets on the frame 1

By means of links 9, a tray 10 with a vibrator 11 is attached to the frame 1. On the carriage 2, an extractor 12 of castings is mounted, consisting of a carriage 13, in which the body 14 is mounted for movement. The carriage 13 has a bracket 16 provided with two rows of holes 15, on which the cover 17 is fixed with the possibility of transverse displacement with the

it rollers 18. Casing 17 has reb 19 with a hole. The housing 14 comprises a tong clamp 20 and a vibrator 21 with guides 22 and 23 attached to it. The guides 22 fastened together by the box 24 interact with the rollers 18 and thereby hold the housing 14 in the carriage 13 with the possibility of mutual movement. A spring 25 is attached to the guide 23 passing through the holes in the rib 19 and the box 24, and a stop 26 is fixed to the vibrator 21 by means of a disk 27 which is attached to rotate the bracket 28 of the tong clamp 20. In the bracket 28 on the axis 29 are rotated pneumatic cylinders 30, driving jaws 31 with teeth 3 Jaws 31 are mounted to rotate on axis 33 in bracket 28. Eyes 34 are mounted on trolley 2 to fasten bracket 16 in them by means of 35 o axes. mold 36 with cast bushes.

The installation for separating castings from runner systems works as follows.

The molding line, pushing out the manufactured mold, moves the entire stack of molds along the cooling conveyor 5. In this case, the mold 36, to

When setting up the automatic molding line, the molds are not cast, while during T from the moment the sponges began to be introduced into the mold, the tongs gripped back to the initial position, at which the sponges 31 were located at the distance M from the edge of the cooling conveyor, and the vibrator 21 stopped working another movement of the stack of molds along the cooling conveyor, which serves as a command to turn the vibrator on again and insert the jaws 31 into the mold.

If the mold is cast, the tooth 32 of the jaws 31 abuts the gating system and the further introduction of the jaws into the mold is stopped. Therefore, during the time T, the body 14 does not return to its original position relative to the carriage 13, in which the limiter 26 abuts the box 24 "

After this, the casting bush is clamped, and pneumatic cylinders 30 are mounted on axis 29 in bracket 28 mounted on vibrator 21 using disk 27 o. Vibrator 21 continues to operate. Drive 3 moves cart 2 with 12 extractors fixed on it along frame 1 „

The casting bush is extracted from the

a stack at the end, acting on a tapering jig on the tong clamp 20, moving the vibrator 21 with guides 22 and 23 relative to the carriage 13 with rollers 18. At the same time, the trolley 2 under the action of the actuator 3 remains in place and the mounted on the guide 23, the spring 25 is compressed between the moving vibrator 21 and the fixed edge 19 of the casing 17. The movement of the body 14 relative to the carriage 13 serves as a signal to turn on the vibrator 21 for a time T,

During the time T, tick sponges can be (embedded) at a distance (figure 2), where P is the distance from the edge of the jaws 31 to the teeth 32; M is the maximum axial size of the mold, which is equal to the maximum length of the mold when the teeth of the 32 jaws 31 of the tick grip are inserted into the stack of molds.

Under the action of the vibrator 21 and the spring 25, the tong clamp 20 is inserted with the jaws 31 fixed to the axis 33 in the bracket 28 into the mold 36.

As the tick clamp 20 is removed with the casting bush from the end of the stack of molds on the cooling conveyor 5 under the action of the spring 25, the body 14

40 returns to the initial state with respect to the carriage 13. Tick-borne gripper 20 extends above the supports 7 stops 6 "fixed to the holes in the beam 8"

45, the beam 8 and the structure of the uprights 7 can allow the tong tong 20 to pass between the uprights. The castings are knocked off from the bush with the pillars 7 and p are given onto the embossing grid 4. In the sponge

gQ 3 only the gate system is clamped.

Cart 2, without stopping, continues to move the extractor of the joints 12 along the axis of the knock-out grating in

55 side of tray 10.

After trolley 2 stops above block 10, sponges 31 are opened, vibrator 21 continues to work, and the runner system falls on tray 10,

  having a vertical connector,

As the tick clamp 20 is removed with the casting bush from the end of the stack of molds on the cooling conveyor 5 under the action of the spring 25, the body 14

returns to its original state with respect to the carriage 13. Tick-borne grip 20 passes over the legs 7 of the stops 6 fixed to the holes in the beam 8 8

the beam 8 and the structure of the uprights 7 can allow the tick grip 20 to pass between the uprights. The castings are knocked off from the bush by the pillars 7 and fall onto the embossing grid 4. In the lips

3, only the gating system remains clamped.

Cart 2, without stopping, continues to move the extractor castings 12 along the axis of the knock-out lattice in

side of tray 10.

After the trolley 2 stops above the tray 10, the sponges 31 are opened, the vibrator 21 continues to work and the gate system falls on the tray 10,

attached by means of links 9 to frame 1. The vibrator I1 of tray 10 is turned on and the sprue system is transported to a special box. Dropping sprue system with sponges 31 vibrator 21 stops its work. The drive 3 returns the carriage 2 with the extractors of 12 castings fixed on it to the initial position on the frame 1. When the molding line is triggered again, the cycle of operation of the unit for separating the castings of hinge systems repeats.

Adjusting the vertical position of the retrieval castings relative to the trolley 2 is carried out by installing the axles 35 in the holes 15 of the bracket 16 corresponding to the desired position and in the lugs "

Adjusting the horizontal position of the extractor 12 castings relative to the axis of the cooling conveyor 5 is accomplished by appropriately horizontal displacement of the casing 17 relative to the bracket 16. This is achieved, for example, by making slots in the casing 17 for attaching the bracket 1b to them. Racks 7 are installed in the castings required for this type of casting the holes in the beam 8 and in the pipe positions relative to the beam.

 The force of the beating of the castings from the gating systems is significantly reduced when performing pinches in the places where the gating system is supplied to the castings. With steel casting there is no need to use a special matrix. In iron casting, the brittleness of the material leads to a decrease in the stresses that occur when casting castings.

The proposed installation allows you to automate the separation of castings from gating systems at horizons

uninterrupted molding, as well as provide the ability to reconfigure the gripping unit when the casting bush configuration changes, which expands technological capabilities.
