Description

The invention relates to foundry, in particular to devices for casting molds, and can be used to remove castings from the flask by the method of tilting it.

The purpose of the invention is to simplify the design and reduce its energy intensity.

FIG. 1 shows a rotating device in the initial position; in fig. 2 - intermediate position after the full working stroke of the cylinder; in fig. 3 - rotating device after turning; in fig. 4 - intermediate position after a complete reversal of the cylinder; in fig. 5, view A in FIG. one.

The swivel device includes a frame 1, a transfer table 2, a cylinder 3, a double-shouldered corner lever 4 and a slide 5.

The toggle table 2 is a swing arm with two arms, hinged with brackets 6 and 7 axles on the frame 1. The cylinder 3 rod is pivotally connected to the rocker table 2, and its body is with one end of the two arm of the angular lever 4, the other the end of which is connected to the axis 8, which is located coaxially with the axes 7 of the rotation of the turntable.

The corner end of the two-shouldered corner lever 4 is pivotally connected to the slide 5, having a groove 9 in which the finger iO is fixed on the frame.

On the frame 1 is also fixed to the stop 11, which interacts with two shoulders corner lever 4 during the working turn of the toggle table 2.

The turning of the flask 12 using a rotating device is carried out as follows.

When the cylinder 3 is turned on, its rod, extended to the upper end position, turns the throw-over table relative to the axes 7 until the center

The body of the rotary system does not move to the left (Fig. 2) beyond the axis 7 of rotation of the flip table 2. At the same time, the cylinder body 3 remains stationary due to resting the two shoulders of the angular lever 4 on the support 11.

Then, due to the turning point created by the force of gravity P, the remaining part of the turn of the turntable can be up to 180 °.

Reversible table 2 in its movement carries a cylinder. The double-shouldered corner lever 4, connected to the cylinder body 3, rotates about axis 8, and the link 5 moves relative to the finger 10 to the upper position. Shock absorbing devices can be applied to absorb the shock loads that occur.

During the return stroke, the cylinder body 3, resting through the double-shouldered corner arm 4 on the frame 1 and held from the rotation about the axis 8 by the finger 10 through the slide 5, remains stationary. At the same time, its rod moves to the lower extreme position and rotates the transfer table 2 until the center of gravity of the system is shifted to the right of the pivot axes 7 (Fig. 4). After this, due to the turning point created by the force P of the turning point P, the reversing table 2 is lowered and the turning device is moved to the initial position (Fig. 1}

The proposed rotary device, in comparison with the known one, has a simpler structure due to the exclusion of an intermediate drive, which reduces the metal consumption and operating costs. In addition, due to the use of si; 1 ton of tin in a certain part of the rotation of the turntable during its working and return stroke, the power consumption of the device is reduced.
