UNIT FOR MOLDING BUILDING STRUCTURES Russian patent published in 1995 - IPC

FIELD: industry of building materials. SUBSTANCE: equipment has a bed spring-loaded relative to its base, hopper, two pistons with two molding plates and hydraulic cylinder, vibratory table mounted on guides of bed and having an oscillator in the middle connected to the drive and traveling reciprocally in horizontal direction. There are also two molds mounted on trays on the table, two ejectors spring loaded against the bed and driven by the molding plate. Hydraulic cylinders are symmetrical about the vertical axis of hopper. When operating, one of the molds takes its charging position under the hopper, the other takes its position to the right of the hopper for articles to be molded and ejected. As the article ready is being ejected, the mold together with its molding plate rises and the tray with articles is moved on to the conveyor giving place to the tray which follows, and the operation repeats. EFFECT: higher efficiency. 2 dwg
