Abstract
1,175,778. Injection moulding. D-M-E CORP. 25 July, 1968, No. 35651/68. Heading B5A. An injection mould includes plates 10, 12 defining a mould cavity 16, at least one core pin 22 and/or ejector pin 24 extending through plate 12 and prevented from rotating about their axes by providing transverse slots in their heads 44 and securing the heads in supports 12 or 28 by U-shaped keys 36. The parallel legs of the latter are located in bores 48 in the support and the intermediate legs fit into the slots. Back-up plates 26 and 30 are provided, and the end of the ejector pin lies flush with the cavity wall during injection.
