INSTALLATION FOR MOLDING CONCRETE PRODUCTS

摘要

FIELD: manufacture of articles of building compositions, mainly small-lot articles. SUBSTANCE: installation includes mounted in housing movable frame with pair of symmetrically arranged unbalance oscillation exciters, guiding columns mounted in pairs in two column base in such a way that pitch of guiding columns in column base corresponds to 0.4 - 0.8 of their interaxial spacing. Lower and upper traverse bars are mounted with holders embracing guiding columns along the whole molding zone. On punch of upper traverse bar pair of symmetrically arranged unbalance oscillation exciters is mounted. Axes of said exciters are arranged normally relative to axes of oscillation exciters in movable frame in order to provide possibility for creating vertical resonance oscillations at molding. In lower traverse bar die is mounted with possibility of engaging (through pallet) with movable frame at period of molding at transmitting fixed pressure value to said frame. Said die includes guide pins for fixing pallet. Supply hopper with box-type feeder is mounted in additional guides with possibility of displacing said guides out of molding zone. EFFECT: enhanced efficiency, enlarged assortment of products. 5 cl, 7 dwg
