Abstract (en)

[origin: GB2410001A] A mould for injection compression moulding of an article, comprises a female mould part 10 and a core 16 for mounting in use on the platens of an injection moulding machine for movement towards and away from one another between an open and a closed position. A sealing ring 20 surrounds the core 16 for effecting a seal between the female mould part 10 and the core 16. The core 16, the female mould part 10 and the sealing ring 20 together define a closed mould cavity as the core approaches the closed position. In the invention, the sealing ring 20 has a tapering surface 22, 24 that seals against a tapering surface on the core 16 as the core 16 reaches the closed position.
