Forming machine model 4836 pneumatic shaking with additional pressing. Designed for the manufacture of one-time half-molds from sandy-clay mixtures in the conditions of small-scale and batch production.
The machine is a single-position installation with a rolling traverse moving step by step to the forming position. The main unit of the machine is a shaking table with a built-in vibrator. The base of the machine is a steel casing with a centrally located press and four exhaust pneumatic cylinders.
The machine works as follows.
A flask is installed on the press-shaking table and filled with molding sand. Compressed air is supplied to the cavity of the shaking piston, through which the piston moves upward. When it rises, air is cut off under the piston, then exhaust. When the table falls, a shock (shaking) occurs. The shaking process continues as long as compressed air is supplied to the piston cavity.
After the end of the shaking process, the traverse with the press plate is rolled to the pressing position. Compressed air is supplied to the pressing and drawing cylinders. The pressing piston presses the flask against the press plate. The final compaction of the molding sand in the flask takes place.
