PRESS MOULD FOR FLOW MOULDING Russian patent published in 2009 - IPC B29C45/02 

FIELD: machine building.

SUBSTANCE: present invention pertains to machine building and can be used in making rubber objects through flow moulding a rubber mixture in a press mould, for example, parts of a solid-propellant rocket engine. The technical outcome is achieved through use of a press mould for flow moulding, containing a matrix, loading chamber, die and running channels. The running channels join the cavity of the matrix with the loading chamber. In the loading chamber between the die and the running channels a circular plate is fitted with provision for axial displacement, with circular material samples in the centre part on the side of the die and on the side of the running channels. There are through-openings on the plate in the zone of the material samples, uniformly arranged on the surface of the plates.

EFFECT: increased material utilisation when making objects from rubber mixture in a press mould using flow moulding.
