Abstract

1436107 Injection moulding hollow articles CHLORIDE LORIVAL Ltd 23 July 1973 [25 July 1972] 34802/72 Heading B5A The invention relates to an injection mould for making hollow thermoplastic articles comprising a die 12 into which a punch 15 projects, means for locating the punch and die in relation to one another including male and female locating members and means for moving one locating member relatively to the other during the moulding operation. According to the invention, one of the locating members is formed as an injection nozzle 26 and the movable locating member 20 is retained during the major part of the injection operation with the locating surfaces spaced by a narrow clearance 30 (Fig. 3) substantially less than the wall thickness of the article, and during the final part of the injection operation the locating member is retracted so that the clearance is comparable with the wall thickness. The clearance 30 may be about fifteen thousandths of an inch. The article may be a part of a ball pen but, as shown, is an electric battery container. The punch 15 comprises six separate slabs 16 with narrow spaces 17 therebetween forming the intercell partitions. In Figs. 3, 4 the female locating surface 21 is carried by the core slab 16 and is retractable, and the male locating surface is carried by the die 12 and forms the injection nozzle 26. If desired, the male locating surface may be formed on the core slab, and may be retractable and the female locating surface may form the injection nozzle (Fig. 6, not shown) or any combination of these arrangements may be used. The movable locating member 20 may also act as an ejector. The mould opening and article ejecting arrangements are as in Specification 1,436,108.
