Description

The invention relates to devices for the dosing of material, to molds and can be used in the chemical industry in the processing of plastics.

A device for filling containers with material is known, which contains a material hopper connected to a metering chamber. At the same time, elastic elements with a drive are mounted in the bunker to prevent arching 1.

A disadvantage of this device is its complexity caused by the need for a vibrator to shake the elastic elements.

The closest in technical essence and the achieved result to the invention is a device for filling molds with a material containing a material hopper connected by means of a flexible hose with a dosing chamber located under the hopper and mounted with the possibility of horizontal reciprocating movement 2.

A disadvantage of the known device is the possibility of formation of plugs and material sticking in the flexible hose.

The aim of the invention is to increase the filling reliability by preventing the material from sticking in the hose.

This goal is achieved by the fact that the device for filling the molds with a material, containing a material hopper, connected by means of a flexible hose to a dosing chamber located under the bunker and mounted with the possibility of horizontal reciprocating movement, is provided with

flexible hose elastic elements, the upper ends of which are fixed in the bunker. The drawing shows a device for filling molds with a material, a general view.

The device includes a hopper 1, a flexible hose 2, a transporting mechanism 3 with a screw 4 and a dosing chamber 5.

In the longitudinal direction of the flexible hose 2, elastic elements 6 in the form of steel spring-loaded filaments (wires) are secured in the bunker.

The device works as follows.

The bunker 1 is filled up with material 7, which is fed through the hose 2 to the screw 4 of the conveying mechanism 3. Next, the press material is fed into the dosing chamber 5 with a screw 4. A command is given to the drive (not shown) of the conveying mechanism to move it towards the mold 8.

The mold 8 is filled with material 7 from the metering chamber 5. When the transporting mechanism moves, during the process of loading the material into the mold, the hose 2 and the elastic elements 6 placed in it are bent at equal angles, creating

all pivot effect (the wire moves inside the hose in the transverse direction). The transport mechanism is then returned to its original position, and then the cycle repeats.

Thus, pulling inside the feed hose in the longitudinal direction of the elastic elements fixed in the hopper will improve the reliability of filling the mold with material by improving its flowability when passing through the flexible hose.
