MOULDING SYSTEM FOR CARDBOARD CONTAINER PRODUCTION Russian patent published in 2013 - IPC B31B43/00 B31F1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to production of container from cardboard. Proposed system comprises moving and fixed mould halves arranged opposite each other. Container has bottom from compacted cardboard blank, walls attached thereto and rim partially moulded from plastic and attached to top edge of said walls, all along their edges. Mould moving half comprises at least core plate and flat compaction frame to displace relative to said core and has compaction surface and surrounds said core. Besides, said half has limiting frame to be arranged between said core and compaction frame. The limiting frame allows making of said rim and displaces relative to both compaction frame and said core. Mould fixed half comprises at least one mould plate with cavity and compaction surface. Proposed moulding system comprises insert to rest on mould bed to coupled therewith. Said insert decreases mould cavity depth H by its height h so that insert continuous surface doubles as a new bottom for mould cavity. Note here that length H of core section extending inside mould cavity in moulding cardboard blank may be decreased by insert height h by replacing plate core with shorter core or split joint to core invariable-length base part or to variable-length adapter part. It results in possibility to use mating core or core adapter parts and bed inserts to vary depth of cardboard blank depth, that is, the distance from container bottom to top edges of its walls.

EFFECT: productions of various containers with separation baffles.
