METHOD OF SEMIDRY PRESSING AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC B28B3/00 B30B11/00 

FIELD: construction.

SUBSTANCE: invention is related to the field of construction materials production. Method for semidry pressing includes batched loading of moulding mix into press-chamber, its compression with preliminary pressing, technological maturation, final repressing and ejection of finished product. Device for semidry pressing comprises bed plate, table, power hydraulic cylinder, orifice 6, feeder, gate-batcher and mechanisms for moulding and ejection of product 28. At the same time mechanism for moulding is arranged in the form of press-chamber 30 with varied closed volume, vertical walls of which are created with crosswise arranged side puncheons 34, 35, 37, 38 with the possibility of their reversible motion, upper and lower bases, is equipped with crosswise arranged double-arm levers 18, 19, 36, 39, mounted on axes fixed in bed plate. Upper arms of levers 18, 19, 36, 39 are hingedly mutually connected to puncheons 34, 35, 37, 38, one of oppositely directed pair of levers is equipped with program-profiled cams fixed on their lower arms and joined via elastic element with stem of power hydraulic cylinder, the other pair of levers with its lower arms is also hingedly joined with stem of power hydraulic cylinder, upper base is arranged in gate, lower base is mounted under the table.

EFFECT: increased durability of moulding tool and cheapening of manufacturing method.
