Abstract

633,793. Injection - moulding machines. UNITED STATES RUBBER CO. Sept. 25, 1947, No. 26042. Convention date, Dec. 19, 1946 [Class 87 (ii)] A moulding apparatus for moulding jointing material between two parts and described particularly with reference to the moulding of a jointing ring of rubber between inner and outer metal members to constitute a vibration damper, comprises a movable platen supporting one part, a plate carried by and movable relatively to the platen, supporting a second part, means to align the parts by relative movement between the plate and the platen, and a device for injecting mouldable material between the parts so as to fasten them together. The apparatus has a fixed crosshead 7 supporting a plunger 37 having a sealing groove 44, an 'intermediate movable platen 25 carrying a pressure cylinder 28 with injection openings 35 and a guide surface 36, and a lower hydraulically operated platen 8 which supports a relatively movable plate 20 and co-operates with an ejector plate 17. The parts 2, 3 to be joined are positioned as shown in Fig. 1, on the spring-mounted plate 20 movable in the recess 21, and on the bearing surface 11 respectively. Springs 22 support the plate 20 so that it normally projects above the surface 11. Outward movement of the plate is limited by guide pins 23. The plate 20 is of the same diameter as the part 2 which is a sliding fit on the tapered guide ring 19. On moving upwardly under hydraulic pressure the platen 8 carries with it the plate 20 and the parts 2, 3, the part 2 contacting the surface 46 of the cylinder 28 first, and thereby being aligned with the part 3. The platens 8, 25 then move upwardly together until the plunger 37, by means of the tolerances 41, 32, aligns with and enters the cylinder 28, injecting the material 34 between the parts 2 and 3. After injection the platens move downwardly ; the stops 26 halt platen 25, but the platen 8 continues its downward motion until the ejector plate 17 forces the pins 12 upwardly to eject the finished article.
