MACHINE FOR COMPRESSION MOULDING Russian patent published in 2010 - IPC B29C31/04 B29C43/34 

FIELD: machine building.

SUBSTANCE: machine for compression moulding consists of wheel (22) rotating around axle and of multitude of dies (52) arranged around the wheel with angular interval. Each of the dies consists of the first segment (54) of the die and of the second segment (56) of the die. At least one of the segments of the die is movable relative to another segment between a closed position for compression moulding of a plastic item and an opened position for removal of moulded item from the die and for loading die charge into the die. A device (130) is designed for successive placement of die charges into the dies. The device includes: plate (320) rotating around the first axle and mechanism (324) of placement of charges in the die locating at periphery of the plate; also the mechanism of placement of charges in the die contains a positioning lever (330) rotating around the second axle perpendicular to the first axle and cartridge (332 or 332a or 332b) at the end of the lever for placement of die charges into dies passing successively next to periphery of the plate. The device for successive placement of die charges into the compression dies consists of the plate rotating around the first axle and the mechanism of die charges into the die.

EFFECT: improved flow of material at compression moulding.
