Title: Improvements in or relating to injection moulding apparatus
Inventor: BEEBEE BRIAN HARRY
IPC: B29C45/06
Filed: 1964-08-08
Abstract: 1,101,913. Injection moulding machines. DUNLOP RUBBER CO. Ltd. 27 July, 1965 [8 Aug., 1964], No. 32380/64. Heading B5A. Moulding apparatus comprises a turntable 9 having a plurality of apertures 10 in which moulds 30 are located, means for indexing the turntable to locate the moulds successively in a plurality of stations, a pair of heated platens 18, 19 disposed one on each side of the turntable, and a ram 20 for moving one of the platens to clamp the mould in closed position. The platens may be heated by electrical cartridge heaters or by steam. The invention eliminates the necessity for rotary seals and slip rings for supplying heating &c. services to rotating moulds. The example described is a machine for injection moulding rubber boots in moulds comprising hinged parts 31, 32, 33, the part 32 having a spigot 34 for location within an aperture 10. A link 36 is pivotally connected to mould parts 31, 33 so that when the upper mould part 31 is swung upwardly through 90 degrees the front part 33 is moved away from the lower part 32. Mould part 31 is opened by a doubleacting pneumatic cylinder 11 whose piston rod 12 carries a roller 13 engaging a tongue 41 on the upper mould part. Spring loaded plungers 15 assist in closing the mould part 31. An internally pivoted member 40 carrying a pair of lasts is moved to the 45 degrees position shown during the second half of the 90 degrees opening movement of the upper mould part 31. In Fig. 1 (not shown) a is a loading station, b an injection station, and c to f are curing stations. The curing stations are each provided with heated platens 22, 23 the lower platen being movable upwardly by a fluid-operated ram 24. Between the stations the moulds are relieved of pressure and are unheated. The injection head 17 may be horizontal (as shown) or vertical.
