Description

The invention relates to a foundry ;; production, in particular to devices for the manufacture of horizontal stack forms.

The purpose of the invention is to simplify the con- struction and improvement of the service conditions of the molding machine.

FIG. 1 shows a molding machine, side view, in FIG. 2 - rae-- cut A-A in FIG. 1, in FIG. 3 shows a section B — E in FIG. 2. .1.

The flaskless molding machine consists of a bed 1 on which carousels 2 and 3 are installed, inside which the press mechanism 4 and the piston mold 5 are removed from the molding chamber on the conveyor 6. A sand blowing unit 7 is installed above the shaping position I, next to the carousel The blowing and spraying units of models 8 are installed at the position prior to shaping. On the carousel 3 vertically mounted are radially movable frames 9, having spring-loaded devices 10 returning the initial position to Model plates 11 are fastened on the carousel 2. Molding chambers 12 are installed inside which are movable vertical frames 13, which have spring return devices 14 which are fastened to the original 15.

Model plastic automatic flask molding works as follows.

Synchronously rotating carousels 2. and 3 stops so that the molding chamber 12 gets under the sandblasting unit 7, the movable frame 9 with the model plate 11 is placed against the carousel, 3. Then the slider of the pressing mechanism 4 pushes the movable frame 9 and inserts into the molding cavity chambers 12, model plate 11, after which the inflating sand mixture immediately begins. Pressing mechanism 4, continuing to move forward the model plate 11, makes pressing the mixture

in the molding chamber 12. Next, the slider of the pressing mechanism 4, and then the movable frame 9 with the model plate 11, is returned to its original position by the action of the spring devices 10. At this time, the rods are positioned on position II in the previously prepared mold in the molding chamber 12, and on position III the piston rod 5 moves forward and presses on the frame 13, to which the model plate 15 pushes the mold out of molding chamber 12 on the conveyor 6 and pairs with a horizontal stack of forms. After that, the rod of the mechanism 5, and then the frame 13 with the model plate 15 under the action of the test devices 14 is returned to its original position. In position IV, the model kits are blown and sprayed. After these operations are completed, the carousels 2 and 3 are simultaneously turned one position. The cycle is repeated,
