1290598 Moulding foamed plastics KRAUSSMAFFEI AG 29 April 1970 [6 June 1969] 20528/70 Heading B5A A mould 3, 4 for foamed plastics material can be rotated about two mutually perpendicular axes through at least 90 degrees so that the mould cavity can be orientated to allow the escape of air. The mould is mounted in a machine frame 11 having chains 8 secured thereto so that it can be rotated about an axis b-b to a position where it can be fixed, the part 4 can also be reciprocated by an hydraulic cylinder 12 and clamped to the part 3, so that the mould can be rotated about the axis of reciprocation a-a. The mould in Figs. 2, 3 (not shown) is mounted on pedestals (20). In Fig. 4 (not shown), the machine is mounted at one end about a hinge (19), and moved at the other end by a screw or hydraulic jack (26). |
