DEVICE FOR POTTERY MOULDING Russian patent published in 1995 - IPC

FIELD: building materials industry. SUBSTANCE: turnable provided with moulds, is installed in bearings secured on a fixed horizontal axle secured on a bed frame. Each mould is furnished with two side punches that are hinge-joined to the rods and pistons of hydraulic cylinders. The pistons divide the hydraulic cylinder into spaces hydraulically connected with hydraulic control valves. The pressure hydraulic line and drain hydraulic line are brought to the turnable space through grooves and ducts in the left-hand hub of the turnable. The covers are hinge-joined to rollers installed in the shaped slot of the spatial cam. The pusher is linked with the roller installed in the shaped slot of the flat cam secured to the fixed horizontal axle. The mix to be moulded is fed from the loading hopper to the moulds, then the cover the mould and, in response to a command of controllers of the hydraulic control valve, connects the pressure line to the spaces, and the drain hydraulic line - to the hydraulic cylinder spaces. Two-sided moulding of pottery is accomplished. Then the cover opens the moulds, the pusher pushers out the finished pottery to the discharge conveyer. EFFECT: improved design. 2 cl, 3 dwg
