Abstract:
1. A moulding apparatus for manufacturing a storage container for storage of nuclear radiation material, the container having an inner container part of a first thermoplastic material, an intermediate container part of radiation inhibiting material on the outside of the inner container part, and an outer container part of a second thermoplastic material moulded onto the outside of intermediate container part, the apparatus comprising: first, second, third and fourth locations present along a movement path subdivided into first, second, third and fourth sub-paths, at least one mould core or a plurality of mutually spaced mould cores with longitudinal axis thereof in a vertical posture, having a core base thereof supported from below, and being movable to and locatable successively at said first, second, third and fourth locations with the core base still supported from below and with the mould core still being in a vertical posture at each of the locations, and first, second and third sets of outer mould means, interacting with material injection means, respectively, enabling injection moulding of said inner container part onto the mould core, said intermediate container part onto an outside of the inner container part and said outer container part onto an outside of the intermediate container part at said second, third and fourth locations, respectively, said first, second and third sets each comprising at least two mould parts which are movable in a direction transverse to the longitudinal vertical axis of the mould core at said second, third and fourth locations, respectively, said mould core being with its longitudinal axis in a vertical posture throughout movement of the mould core(s) from the first location to and at the second location, from the second location to and at the third location, from the third location to and at the fourth location, and then further on from the fourth location back to and at the first location subsequent to injection moulding at the fourth location, the mould core(s) at its base being attached to a carousel having rollers or wheels rotatable on a manufacturing plant floor or on rail tracks so as to be movable along a ring-shaped or circular path constituted by said first, second, third and fourth sub-paths and to fully support the mould core(s) and the container parts as they are successively moulded.
