MOLDING MACHINE FOR PRODUCTS OF BUILDING MIXES Russian patent published in 2002 - IPC

FIELD: manufacture of products of building mixes. SUBSTANCE: molding machine has a bed frame with a vibrating table positioned in its vertical axis. The main and auxiliary distributing fixtures respectively for the building mixes of the main and finishing layers of the product are mounted on the bed frame opposite the vibrating table. Located along the inner end faces of the service bunkers of the distributing devices are the front ends of the horizontal guides fastened on the bed frame. A carriage bears against the horizontal guides by means of rollers with guide bushes installed in its longitudinal axis and enveloped by the upper and lower rams. A punch and a die are coaxially fastened on the lower ends of the upper and lower rams respectively, they are connected to the rods of the drive power cylinders fastened on the carriage. The carriage is made in the form of rigidly coupled vertical plates with the guide bushes located on them and symmetric in its longitudinal axis. Transverse beams with rollers bearing against the horizontal guides are fastened on the end faces of the vertical plates. A stopper with a vertically moving delivery table with a changeable inventory bottom plate is positioned under the rear ends of the horizontal under the rear ends of the horizontal guides. Length L of the horizontal guides and distance S from the working surface of the punch in the extreme upper position to the surface of the vibrating table exceeds length L₁ of the horizontally movable carriage and height h of the die by 2.1-2.5 and 1.3-2.6 times respectively, center-to-center distance T of the upper rams is less than center-to-center distance T₁ of the lower rams by 1.25-2.5 times. EFFECT: simplified construction, enhanced capacity. 4 cl, 3 dwg
