Patent GB-869902-A (GB)
Title: Tire curing press
IPC: B29D30/06
Filed: 1958-07-10
Abstract: 869,902. Tyre moulding presses. McNEIL MACHINE & ENGINEERING CO. July 10, 1958 [Feb. 13, 1958], No. 22155/58. Class 87(2). In a tyre moulding press in which fluid is fed directly to the tyre, it is held in place by a ring 15 made up from segments, of which alternate ones are collapsed inwardly and upwardly A as shown in Fig. 5, and the other segments D are then collapsed inwardly, to facilitate the removal of the tyre. In operation, after curing of a tyre by passing steam or hot water through radial passages 61 and syphoning it out through a pipe 71, the press is opened by raising the upper mould 11 carrying with it the upper ring 12. As the ring 12 rises, springs 93 lift the ring 15 upwardly until a flange 90 contacts the heads 92 of pins 91, in which position the ring 15 is clear of the lower mould ring 21 (see Fig. 4, not shown). As the press nears its fully open position, the cylinder 84 is moved upwardly to raise the whole mechanism clear of the lower mould 10, in which position unloading arms 105 engage the underside of the tyre. Hydraulic pressure is then supplied to raise the piston 35 to first collapse the ring segments A, and then the segments D. The unloading arms 105 now raise the tyre of the lower mould ring 21 and over the collapsed segments. While the lower mould ring 21 is still up, an uncured tyre band may be placed thereon. The ring 21 is then lowered, until it seats on the mould section 10. During this action the ring is also lowered in its collapsed position. As the press closes, the hydraulic pressure to the piston 35 is released causing the springs 86 to expand the ring 15. The press is then finally closed and the springs 93 compressed. In a modification, Figs. 11-13 (not shown), a ring 15 is shown with an arcuate insert to allow the ring to be used with tyres of varying rim widths.
