Abstract
1308781 Injection-blow moulding COPE ALLMAN INTERNATIONAL Ltd 19 April 1971 [31 Dec 1969] 63473/69 Heading B5A In an injection-blow moulding process, a parison is injection moulded and transferred on the injection core to a blow mould from which the blown article is withdrawn but is not discharged from the injection core until it is realigned with the injection cavity. As shown in Fig. 6, the apparatus comprises a platen 1, having injection cavity 3 and blow mould cavities 4 and a platen 2 with a sliding block 6 having injection cores 7. A parison 8 is injected on core 7 while a previously injected parison is blown in mould 4. Platens 1, 2 are opened and block 6 moved across before the blown article is ejected and the platens are again closed for injection of a further parison and blowing of the already formed parison 8 in the other blow mould 4. The cycle is then repeated. Neck moulds 9, Fig. 11, may be used. In this case, platens 1, 2 open in two stages; in the second stage, neck moulds 9 are opened to release the blown article while aligned with the injection cavity by a stripper bar 11 which engages push rods 10. The cores may be withdrawn other than axially and may be mounted on a rotating turret.
