POWDER COMPRESSION MOLDING MACHINE AND APPARATUS FOR CONTINUOUS PRODUCTION OF POWDER COMPRESSION MOLDED ITEM USING THE MACHINE

摘要

A powder compression molding machine is configuredsuch that a plurality of lower and upper punches 61, 41 areallowed to enter a plurality of through-die holes 31 providedin first and second molding die sections 32, 33 of a slideplate 3 in a compression molding zone 21 to compressivelymold powder and the slide plate 3 is slid to push outcompacts downward and collect them in compact discharge zones22a, 22b.Even when powder is compressively molded at a lowcompression force into solids having high porosity, compactscan satisfactorily be molded and collected withoutcrumblingness, the compacts having sufficient high porosityand being dissolvable in water or the like.
