Description

The known molding machines for the manufacture of casting molds, which simultaneously manufacture the upper and lower half-molds, allow only buttonless molds to be formed and require a double number of actuators.

In the proposed molding machine, these disadvantages are eliminated by the fact that sandblasting and sanding heads are located one above the other.

FIG. 1 shows the Mai | ina B section; in fig. 2 - the same, side view.

The top / and 2 sandblasted heads are located above each other. .1 between them there is a cassette 3 with model plates "top 4 and" bottom 5 and a bottom pressing mechanism 6. The bottom sandblasting head 2 has a volumetric inflatable slab 7. The mixture is loaded into the lower head by a box-shaped dispenser 8 from the side baxra 9, and the top one directly from the hopper 10. The bottom head is fixed on the pneumatic cylinder table //.

The steamed flasks 12 and 13 from the knockout are simultaneously fed to the mold in position /. After that, the pneumatic cylinder piston // moves upward, during which the inflatable plate 7 connects to the head 2, the bottom box 13 with the help of the pin pins sits on the plate 5, and the top box 12 sits on the plate 7. N all this is pressed against the upper sand-blowing plate. head. From the upper and lower sandblasting heads, the mixture is blown into the flasks and the lower extrusion is performed. Thereafter, the models are pulled from both half-molds, and the formed half-forms are removed from the compaction position and are fed to install rods and assemblies.

Subject invention

The molding machine for the manufacture of casting molds in the form of a bent-blown-up rimming method with pressing, characterized in that, in order to increase productivity by simultaneously making the "top and" of the mold, the sandblasting and sandblasting heads are located one above the other.
