Description

I

The invention relates to foundry, in particular, to molding machines with sandblasting devices.

A known device for the manufacture of rods, containing a frame, a sandblast tank, is moved from the filling position of the core box with the mixture to the filling position with a mixture of sand-blowing tank, a blowing mechanism, a hopper for a mixture with a loading neck, overlapped with a gate.

The purpose of the invention is to eliminate the requested mixture when loading and moving the shotgun.

This is achieved by the fact that the installation is equipped with a U-shaped frame, which surrounds the upper part of the sandblast tank, suspended on it by means of pins, and. a vertically mounted piston actuator, the stem of which the hinge is connected with the crossbar of the frame, and the ends of its lateral sides are pivotally connected to the frame.

FIG. 1 and 2 depict the proposed plant for the manufacture of rods; on

FIG. 3 and 4 - boot device; in fig. 5 - loading device during filling with sandblasting tank mixture. The installation consists of a frame 1, a sandblast {5-tank-2, moved from the filling position of the core box 3 to the filling position in the tank and connected with the pneumatic cylinder 4, moving the pumping mechanism 5 mounted on the base on the filling position of the core box 3 with a mixture, hopper 6 with a vibrator 7 permanently mounted on the frame 1 at the filling position of a sandblasting tank with a 2-mixture, mechanism 8 for receiving and transporting steraes. The blending of the mixture from the tanker is prevented by cruciform shutters 9, installed in the loading opening 1O of the bunker 6. The shutters 9 are a glass, in the bottom of which four radial holes are made, overlapped by partial blades of the crosses mounted on the axis in the center of the bottom of the glass. The location of the cross with respect to the holes of the glass is adjustable.

At the filling position, the mixture in the sandblast tank 2 is fitted with a U-shaped frame 11, which, on the outside, embraces the upper part of the sandblast tank 2 suspended on it by means of pins 12, matched when the mixture is loaded with eyelets 13 installed on its sides. In addition, the installation is equipped with a vertical mounted piston piston 14, the stem 15 of which is pivotally connected to the crossbar of the frame 11, and the ends of its lateral sides are fastened to the support 16 by means of axles 17.

The device works in a dim way.

After the equipment has been filled with the mixture of the pitch-drilled tank 2 with the drive 4, it will be mixed along the horizontal direction to fill it with the mixture. Trunnions 12 of a sandblasting tank enter the lugs 13 of the U-shaped frame 11 installed at this position. They include a piston Ornvod 14, the rod 15 of which lifts the frame I from the crossbar. immersed in the loading window of a sandblasting tank (see fig. 5). Include the vibrator 7, a mixture of hoppers. 6 through the holes in the flaps 8 is mixed into the sand blasting tank, filling it to the cruciform gates.

in the zone of the latter, slightly condenses, holding the entire column of the mixture in the bunker ,. thereby preventing it from falling out.

In the reverse order, the sandblasting pei tank is fed to the filling position of the snap rod mix (flat position).

Claims (1)

Formula of the invention nor An installation for the manufacture of rods, a sandblast tank with a drive for reciprocating its movement along horizontal guides, an inflation mechanism and a mixing hopper, characterized in that, in order to prevent spillage of the mixture when loaded into a displacer; With the U-shaped frame, with the outer side, the upper part of the sandblasting tank of the suspension ball is pivoted from the outside, and a vertical shaft with a seam drive, the stem of which is sharvrnb with raskov, and the ends of its lateral sides are hingedly connected to the bed.
