INSTALLATION FOR MOLDING OF ARTICLES FROM CONSTRUCTIONAL MIXTURES Russian patent published in 1999 - IPC

FIELD: manufacture of articles from constructional mixtures. SUBSTANCE: installation has vibration stand with vertical displacement mechanisms mounted on shock absorbers and positioned between main and auxiliary dispensers located opposite to each other. Die and bottomless matrix suspended from rods of vertical-displacement power cylinders mounted on drive carriage are positioned coaxially with vibration stand above its surface. Upper and lower horizontal guides which vacant ends rest on posts are secured on internal ends of support frames of dispersers perpendicularly to their longitudinal axes. Carriage is installed on horizontal guides by means of rollers. It has rolling pins embraced by die and matrix holders. Matrix has insert which forms its operating surface. It rests on matrix and contacts vibration stand surface with its lower end. Piler's reception table is placed under vacant ends of horizontal guides. Spaces between axes of power cylinders positioned on vibration stand and axes of rolling pins are larger than spaces between axes of unbalanced shafts and axes of bottomless matrix power cylinders by 5.0-7.0 and 2.0-3.0 fold, respectively. Space from die in upper position to surface of vibration stand is larger than height of main dispenser box feeder by 1.4-2.5 fold. EFFECT: higher efficiency. 3 cl
