Plate and apparatus for forming a plastic material flanged hollow article |
| 摘要 |
It is disclosed a plate for a mould station to form a flanged hollow plastic container by shaping a flat billet, the plate comprising a base, a frame, an outer core to form a container of a first size and an inner core to form a container of a second size, smaller than the first size, wherein the frame is integral with the base and wherein the frame defines a frame upper surface; wherein the outer core, in a first configuration, is held elastically with its upper surface flush with the frame upper surface and, in a second molding configuration, is held with its upper surface recessed with respect to the frame upper surface; wherein the inner core, in a first configuration, is held elastically with its upper surface flush with the frame upper surface and, in a second molding configuration, is held with its upper surface recessed with respect to the frame upper surface; and wherein a retention system is provided to retain said billet substantially adhering to at least the upper surface of the inner core. |

1. A plate useful for a mould station to form a flanged hollow plastic container by shaping a flat billet in a mould cavity, the plate comprising:
a frame; an outer core to form a container of a first size; and an inner core to form a container of a second size smaller than the first size, wherein: the frame defines a frame upper surface; the outer core, in a first configuration, is held elastically with an outer core upper surface flush with the frame upper surface and, in a second moulding configuration, is held with the outer core upper surface recessed with respect to the frame upper surface; the inner core, in a first configuration, is held elastically with an inner core upper surface flush with the frame upper surface and, in a second moulding configuration, is held with the inner core upper surface recessed with respect to the frame upper surface; and a retention system is provided to retain the billet substantially adhering to at least the inner core upper surface. |
