Title: Improvements in or relating to molding apparatus
IPC: B30B15/30
Filed: 1956-09-10
Abstract: 815,625. Compression-moulding powdered plastic materials. ALESI, J. A. Sept. 10, 1956, No. 27631/56. Class 87(2). A die carrier D is reciprocated vertically by a pneumatic cylinder 12, the movement from the piston rod 12<SP>1</SP> being transmitted through force transfer links 14, 15, Fig. 5. The feeding mechanism is mechanically actuated from the movement of the upper die carrier D by the interaction of cam slots 72, in vertical plates 74 fixed to the die carrier Figs. 2 and 3, with cam wheels 70 carried on shafts which are also the shafts for rollers 44 and are mounted at the front of a feed tray F. The feed tray F, which comprises upper and lower plates 46, 54, is reciprocable beneath a hopper and is guided by channels 38, 40 in which the feed tray rollers 44 run. The channels are connected at the rear by a crosspiece 42. Tubes 50 are arranged in a transverse row in the feed tray and, when the tray is retracted beneath the hopper, Fig. 2, are open at the top to the material in the hopper but are closed at the bottom by a loading plate 56, which is slidable underneath the lower plate 54, being connected thereto by posts 58 which pass through slots 60 in the loading plate. The operation of compressed air valves is electrically controlled by a switching box 100. Air is admitted to the top of the cylinder 12 and the die carrier D descends, the cam slots 72 drawing the feed tray F towards the mould carrier C till, in the Fig. 3 position, the tubes 50 are over the mould cavities 10. A bumper 64 on a trip bar 62 which extends back from the loading plate 56 meets the crosspiece 42 and the forward movement of the loading plate is arrested, the remaining travel of the feed tray thus uncovering the bottom of the tubes 50 when they are over the mould cavities and allowing a measured quantity of the material 68 to flow into them. Ejector pins 84 depend from a bar 90 and pass through the dies 82. The bar 90 is biased downwards by springs 94, which cause the pins 84 to eject those moulded articles which stick to the die as the carrier D rises. An inclined plate E is pivoted at 75 to the feed tray F and is tilted upwards, from the dotted to the full line position, Fig. 3, by projections 77 from the cam plate 74 as the carrier D rises, so that the plate E firees any articles still sticking to the moulds. The plate also acts as a shoot to deflect the articles into a receptacle in front of the machine. The beginnings of the up and down movements of the die carrier are controlled by triggers 110, 108 on a vertical bar 112 which actuate a limit switch 106 carried by the mould carrier. When, on the downward movement of the die carrier D, the dies reach a position just above the moulds, the reciprocating movement will stop unless the switch 106 is actuated by the trigger 110, which will not happen if a moulded article has remained in the mould cavity. Damage due to a fresh charge being pressed against a stuck moulded article is thus obviated. The mould carrier C and die carrier D are electrically heated.

Abstract: <FORM:0944510/C3/1> A wire annealing machine, e.g. for copper wire, comprises a housing 40 formed to provide an upright U-shaped body 42 with two channels 42a and 42b, means for advancing wire longitudinally through the body, e.g. power driven capstans 20, 36 and 52, the latter capstan being inside the chamber part 42c of the body, inlet means, e.g. inlets 82, 83 and 84, for supplying cooling fluid such as water separately to each of the channels, separate outlet means for the cooling fluid preferably including a common outlet 85 at the base of the chamber part 42c for both channels, and a cooling fluid supply, e.g. a tank 16, connected to the inlet means for circulating the fluid through the body 42 from the inlet to the outlet means.  The body may be air-sealed by gaskets and have a restriction in one channel 42a to subdivide it into an upper and a lower portion.  The restriction may be formed by a partition 65 with an aperture in which a tube 67 is placed, both provided with a forwardly facing slot 69 for stringing up the machine when the cover 44 of the housing 40 is swung open about hinges 46, as in Fig. 4. As shown, cooling fluid is continuously supplied to the upper portion of the channel 42a through the inlet 83 and drained off through the drain 86 to prevent the fluid boiling for the protection of the incoming wire where it is hottest, the wire being electrically heated to different temperatures in different sections according to a desired heating schedule by adjusting the machine controls 12 for the transformer 10.  As the wire descends, it encounters fresh turbulent cooling fluid (water) at the inlet 84 in the lower portion whereby the insulating steam jacket on the wire is stripped resulting in rapid cooling of the wire.  The inlet 82 for the other channel 42b serves to produce a downward flow of fluid opposite to the advancing wire to the common outlet 85 and to provide a fluid column above the level of the inlet 83.  After cooling the wire is finally dried by an air wiper 80 supplied with pressurized air from blower 102.
