Description

stop 8, folding folding lever 4 when returning the carriage 2 to its original position. To turn off the mechanism in the initial position on the frame 1, a microswitch 9 is made, and for closing the bead 10 on the carriage 2, the hydraulic cylinder 11 of the turning mechanism and the additional folding lever 12 are pivotally connected. In order to fix the mold at the closing position and actuate the hydraulic cylinder 11 of the turning mechanism, there is a microswitch 13 on the unor.

The device works as follows.

In the initial position, the carriage 2 is located in the left extreme position, and the folding lever 4 under the action of the stop 8 is folded so that the form can freely pass over the device. When the mold arrives at the demolding station, a signal is given to the stroke of the hydraulic cylinder 7, which moves the carriage 2 to the right, while the folding lever 4 takes up a vertical position.

The carriage 2, idling, presses the flap lever 4 onto the lower part of the shape loop and turns it and opens the bead 10 along with it.

With a further increase in pressure, the pressure switch is activated (not shown in the drawing) and sends a command to reverse.

The hydraulic cylinder 7 returns the carriage 2 to its original position, while the support 8 presses against the folding lever 4 and folds it up to the formation of a gap allowing the mold to pass over the device along the molding line. At the end of the carriage stroke, by pressing the lever on the microswitch 9, the hydraulic cylinder 7 is deactivated. After certain operations have been completed, the form with the sides opened goes to the side closing station. At this time, the folding arms 4 and 12 are in a horizontal position.

When the form arrives at the side closing post, a command is given to the stroke of the hydraulic cylinder 7, which moves the carriage 2 to the right, while the lever 4 moves away from the stop 8 and takes a vertical position under its own weight.

Pass idle, folding lever 4 with its upper end presses the form pan, and the lower end presses on

microswitch 13, which gives a signal to the course of the hydraulic cylinder 11.

The hydraulic cylinder And rotates the additional folding lever 12 in a vertical position and at the same time closes the board. After that, the pressure increases, the pressure relay is activated and gives a signal to reverse the cylinders 11 and 7.

Under the action of the hydraulic cylinder 11, the additional lever 12 is folded, and the carriage 2 under the action of the hydraulic cylinder 7 comes to its initial position.

In this case, the folding lever 4 rests on

stop 8 and rotates on axis 5 such that

there is a gap between the lever and the shape,

sufficient for passing forms

molding line.

At the end of the stroke, the carriage 2 presses the limit switch 9, which turns off the mechanism in the initial position.

The positive effect of using the described device is the possibility of closing and stripping the sides of the molds of various sizes without changeover. The use of this device will allow the release of two workers, which will save about 3 thousand rubles. in year.
