Description

The invention relates to devices for the processing of plastics and can be used to automate the process of half-milling articles from powder materials and multi-cavity molds on presses with multi-plate. small-scale production.

The purpose of the invention is to increase productivity by reducing the loading time of the slide cartridge and also increasing the reliability of operation.

The drawing schematically shows the unit, the general view.

The automatic unit contains a hydraulic press 1 with a drain multi-mold mold 2, a vibrating hopper 3 for a press material with a rigidly fixed tray 4, a dosing container 5 mounted on one arm of the lever weights 6, and the capacity 5 is fixed relative to the tray 4 and placed under him, the gate cartridge 7 with containers 8 according to the number of sockets of the molds, while the bottom of the containers overlaps the gate of the cartridge 7. The hub of the cartridge 7 is fixed on the lever 9, installed with the possibility of rotation in the horizontal plane from the drive 10. Besides The unit comprises a carriage 12 driven by the actuator 11, moving along horizontal guides 13, an additional metering tank 14 mounted on the drive lever 15 (lever actuator not shown) mounted on the carriage 12 so as to rotate in a horizontal plane, the product puller 16, mounted on the drive lever 17 mounted on the press with the possibility of rotation in the horizontal plane. To control the operation of all drive units of the unit, it is equipped with a software control system that includes a control unit (not shown) and limit switches 18 (shown only for carriage control). .

The unit works as follows.

From the vibrating hopper 3, the powder material is fed through the tray 4 into the dosing weighing container 5, mounted on the scale lever 6. When a given dose is set in the container 5, the material from the container 5 is transferred to the dosing container 14 located underneath. that the initial dosing capacity 14 is installed above the extreme opening capacity 8 of the slide cassette 7. On commands from the software control system of the complex, all the drive devices of the complex are turned on and off. Therefore, nocVie weighing the first dose and loading

The container 8 of the slide cassette after the second batch is filled from the hopper 3 into the metering container 14 is turned by the lever 15. by a movable drive (not shown) around an axis in a horizontal plane until it is overestimated over the next container 8 of the cassette 7, which is in the same row the same as the first loaded container 8. Then the carriage 12 moves along the guides 13 in a step until the dispensing container 14 is combined with the extreme capacity 8 of the next row of gate cartridge 7. The cycle of loading of the tank 8 and the next row of cartridge 7 is repeated.

Before filling all containers 8 of the slide cassette 7, after filling all containers 8 of the slide cartridge 7, the lever 9 rotates in a horizontal plane and transfers the slide gate cartridge 7 towards the mold and sets the cartridge so that the axes of the containers 8 coincide with the axes of the mold slots 2. The bottoms of the containers 8 when the gate of the cartridge 7 moves, opens and the press powder fills the nests of the mold 2. The hub cassette 7 is returned by the lever 9 under loading to the vibrating tank 3 under the dosing capacity 14 mounted on the carriage 12. On the press 1 pressing and holding under pressure

compressible material.

At the end of the pressing cycle, the press 1 opens and the products by the presses of the mold 2 are pressed over it, the lever 17 with the puller 16 turns to the press

and removes the product from the pushers. At this time, the containers 8 of the slide cassette 7 are filled with press powder, the cycle of operation of the unit is repeated.
