Moulds For Use On Injection Moulding Machines

A cap mould for use in injection moulding containers

, for example, comprises a pair of mould parts movable between open and closed positions and which define between them a mould cavity, co-operating frusto conical locating surfaces being provided on the mould parts for determining their relative radial positions with the locating surface on one of the mould parts being radially adjustable relative to the portions of the cap mould parts which define the cavity. The adjustable locating surface may be provided on a locating ring which is preferably divided into a plurality of segments, each of which is separately mounted on the mould part and individually adjustable in the radial direction by a respective screw.

A cap mould for an injection moulding machine, comprising: a pair of mould parts which are movable along an axis towards and away from each other between open and closed positions, said mould parts each having moulding surfaces including side walls which, in said closed position of said mould parts, define a mould cavity; location means carried by each of the mould parts including locating surfaces, additional to said moulding surfaces, which co-operate when said mould parts are in said closed position and determine the relative positions of said mould parts radially of said axis and determine the relative position of said side walls, said location means of one of said cap mould parts being adjustable thereon for moving said locating surface of said one mould part relative to said side wall moulding surface of said one part to thereby adjust the relative radial positions of the side walls of said moulding surfaces when the mould parts are in said closed position.

This invention relates to cap mould for use on moulding machines of the injection type, intended or suitable for moulding thin walled containers or the like, in which it is desired to maintain small tolerances on radial dimensions of an article such as a plastic container.
