Abstract
A blow moulding tool incorporating a core mounted on a stationary press platen and a cavity tool mounted on a rising platen and including an injection gate via which a parison is moulded to surround the core. When the cavity tool has been raised clear, two ancillary split mould shells converge laterally to enclose the parison. Air is then injected around the base of the head of the core to dilate the parison to fit the larger cacity of the split shells. The shells then part to allow a stripper ring around the base of the core to rise and disengage the moulding from the core. The equipment is compact and quick cycling and does not involve lateral shifting and associated chilling and draping of the parison prior to dilation. The shell movement may be linked with the press platen movements or power system.
