Description

one

The invention relates to foundry, in particular, to devices for tilting and stretching of casting molds,

The purpose of the invention is to simplify the design, reduce the metal consumption, reduce the height dimensions and increase the efficiency of the rotator.

Fig. 1 shows a schematic of a rotary-exhaust machine, starting position, side view; in FIG. 2, the same plan view; Fig. 3 is the same, in an intermediate position during forward rotation, side view; FIG. 4 is a section A-A in FIG. 3; FIG. 5 is a section BB in FIG. 3; Fig 6 is a side view of the machine in a position before stretching the half mold; Fig, 7 - the same, in an intermediate position when turning back, side view.

The rotary exhaust machine contains frame I, rotary device 2, exhaust table 3, roller tables 4 and 5, stops 6 and 7, Rotary device 2 contains levers 8 mounted on axles 9 installed in frame 1, and rotation cylinders 10 and 11, one ends of which are provided with rollers 12, mounted on a common axis I3. With a common axis 13, the cylinder rod J4 is associated with a change in its position. The frame 1 has rulers 15 dp of interaction with the throttles mounted on the rotation cylinders 10 and 11. axles 18, fixed on the levers. Earrings 19 are loosely fitted on the axis x 18 and connected to the other ends (rods) of the cylinders 10 and 11, the frame 1 is equipped with guides 20 for the rollers 12 of the cylinders 10 and 11,

The hoisting machine operates as follows.

60104a

The mold 16 moves into the machine on the roller table 5 and stops, for example, by a slam-shut (not shown). The clamps 17 clamp the foundry

5, the form 16, simultaneously the cylinder 14, by changing the position of the common axis 13 of the rollers 12 of the cylinders of rotation 10 and 11, moves the latter to the position B, the working fluid is supplied to the piston

0 cavities of cylinders 10 and 11, and cylinder rods connected with levers 8 extend and rotate the latter together with half-mold 16 and grippers 17, levers 8 rotate on axles

 5 9 installed in the lugs of the frame 1 and when the center of gravity of the parts to be rotated goes beyond the plane passing through the axis of rotation 9 of the levers 8, the working fluid flow is switched by means of the rulers 15 so that cylinder rods 10 and 11, pushes them into cylinder liners, which in this case work as brakes. After rotation, the levers 8 are supported on the support 7, the Exhaust table 3 rises to the upper position, the grippers 17 expand the mold 16, the extraction table 3 descends; ,

30, a linear mold 16 is drawn, which is mounted on the roller 4 and transported for further processing. The cylinder 14 moves the common axis 13 of the rollers 12 of the cylinders 1O and 11

35 to position 1, the working fluid is supplied to the piston cavities of the cylinders, the levers 8 are raised by the cylinder rods and turned in the opposite direction. After the center moves 40 tons of turning parts, the rotary part passes through the axis of rotation 9 of the levers 8, switches the flow of the working fluid, and the turning part acts on the shafts of cylinders Yu and 11, pushing them into the cylinder liners, which in this case work as brake devices. In the extreme position, the levers 8 rest on the support 6, Further

50 machine cycle is repeated.
