An injection moulding device for making articles from at least two injection-moulded parts, comprising
an injection-side mould portion (10) with two equal first injection-side moulding cavities (11a, 11b) for moulding an outer surface of a first part (2) a second injection-side moulding cavity (11c) for moulding an inner surface (1a) of a second part (1) and a void cavity (11d) these latter cavities being rotary by 180º;
the ejection-side mould portion (12) rotary by 180º and with two first equal ejection-side moulding cavities (13a) for moulding an inner surface (2a) of said first part (2), and two second equal ejection-side cavities (13b) for moulding an outer surface of said second part (1),
welding-gate-forming patterns (14) in the second injection-side moulding cavity (11c), in each first equal ejection-side moulding cavities (13a) or in both said second injection-side moulding cavity (11c) and each of the first equal ejection-side moulding cavities (13a), the welding-gate-forming patterns (14) being designed to form injection-moulded welding gates (15) so that, when a welding material (6) has been injected into the welding gates (15), the welding gates (15) on the inner surface (1a, 2a) of one injection-moulded part (1, 2) become welded to the inner surface (2a, 1a) of the other injection-moulded part (2, 1). |
