POWDER COMPRESSION MOLDING MACHINE HAVING AN ARRAY OF PUNCHES ARRANGED ABOVE AND BELOW DIE HOLES

摘要

A powder compression moulding machine is configured such that a plurality of lower and upper punches (61, 41) are allowed to enter a plurality of through-die holes provided in first and second moulding die sections of a slide plate (3) in a compression moulding zone (21) to compressively mould powder and the slide plate is slid to push out compacts downward and collect them in compact discharge zones (22a, 22b). Even when powder is compressively moulded at a low compression force into solids having high porosity, compacts can satisfactorily be moulded and collected without breaking, the compacts having sufficient high porosity and being dissolvable in water or the like.
