Abstract

1430579 Compression moulding; reinforced articles GKN SANKEY Ltd and ARO PLASTICS DEVELOPMENT Ltd 13 July 1973 [21 June 1972] 28973/72 Heading B5A Articles having a reinforcing rib which encapsulates a reinforcing core are compressionmoulded from thermoplastic or thermosetting material by supporting the core solely by supports mounted in a lower mould part, placing moulding material in the mould part over the core and placing an upper mould part thereon and pressing the material to cause it to flow around the core and then withdrawing the supports into the lower mould part while the material is still flowable so that it flows into the voids formed by the removal of the supports. As shown in Fig. 3, lower parts 7, 10 and upper mould part 11 define between them a moulding cavity 12 with an elongate rib-forming portion 15 in which core 20 is supported by the upper concave surface 19 of sliders 18 at their advanced position 21. Sliders 18 are movable in holes 17 by means of a rack mechanism 22 of which a rack 23 has teeth 25 at an angle to its longitudinal axis and engaging teeth 26 on blocks 24 connected to sliders 18 so that longitudinal movement of rack 23 produces movement of sliders 18 in the holes 17. In a second embodiment (Fig. 4, not shown) core (29) is supported by pins (30) movable by hydraulic cylinder( 31). In Fig. 5 (not shown) core (35) is supported by three-part supports, each comprising a central pin (37) engaging the core underneath and two outer pins (36) engaging the sides of the core and having curved surfaces (38) so as to be flush with the rib surface on retraction. In Fig. 7 (not shown) the outer pins (44) are rotated so that curved surfaces (48) thereof form the surface of the rib cavity.
