Abstract
1,036,779. Blow moulding. WORSON S.A. Nov. 25, 1964, No. 47981/64. Heading B5A. An injection-blow moulding apparatus of the kind described in Specification 906,543 comprises a core 23a which is located in and defines a mould cavity in an injection mould 45 for forming a pre-form 63 and is then transferred to a blow mould 46a, 52 for inflation of the preform to form a container 44a. The core 23a is fitted over a member 26a extending from a base 33a and has a limited vertical movement to provide an annular inflating orifice 31a. During injection, the injection pressure forces the core 23a downwardly to effectively close the orifice 3 la but on transfer to the blow mould the spring 60 raises the core 23a to the extent determined by screw heads 57 and so opens the orifice 31a. The neck 68 of the container is formed by compression between the mould parts 33a, 46a, 39a the latter having a passage 41a for coolant. Heat exchange oil is circulated in passages 55 between the core 23a and the member 26a. A sealing ring separates the inflating air and oil circuits. The spring 60 may be omitted and the oil passages may be entirely in the member 26a.
