Abstract: 1464780 Lubricating moulds ING C OLIVETTI & C SpA 1 Nov 1974 [5 Dec 1973] 47435/74 Heading B5A A mould for compacting metallic powder is lubricated by charging the lubricant, e.g. zinc stearate powder, electrically and maintaining the mould at a potential whereby the lubricant is attracted to its walls. In Fig. 1 the lubricant is mixed with dry air in a reservoir 10 and conveyed by a flexible pipe 1 to a Corona charger 40 fed by a D.C. power source 60. The charged particles pass via a pipe 2 to a distributer 65 on a feed shoe 100 of a powder compacting press. The shoe is mounted on a pivot 200 and overhangs the electrically earthed mould 151; the shoe is swung over the mould opening 149, and a needle valve in the distributer opened to allow the injection of air-powder lubricant into the mould from nozzles, not shown. The needle valve is then closed and the air-powder mixture flows from the distributer through a flexible pipe 3 to a re-cycling blower 90 which returns it to the reservoir. The shoe is then swung further about its pivot to allow the mould to be filled with powder from an outlet 101. The press mould of Fig. 3 includes a mould 151, 152, plungers 121, 169 operated by cams 132, 177 and levers 128, 173 to effect a pre-compaction, and electric coils 134 which, when connected to electrically charged capacitors, effect a final compaction via plates 136 and the plungers. The feed shoe is swung by a cam 212 on a shaft 133 and levers 207, 208. A lever 214 is fixed to the shaft 133 and when its end 215 approaches a sensor 95 an electromagnet is energized to operate the distributer needle valve ensuring its operation at the appropriate time.

The system is particularly useful for polymerization reactions within the vessel where it is first necessary to supply heat to the vessel to start the reaction and is thereafter necessary to remove heat from the vessel. When the system is operated to withdraw heat from the vessel, the heat transfer fluid, which may Freon (registered trade mark) or water, is vaporized in the tubes 3 and then condensed in the cooling device 60. On the other hand when heat is supplied to the vessel, fluid entering the tubes 3 as vapour is condensed and returned to the device 63 for revaporization. In a modified system (see Fig. 3, not shown) a compressor (8) and an expansion valve (9) are disposed on opposite sides of the cooling device when additional cooling of the heat transfer fluid is required.

The barrels 1 and 3 may contain plasticizing screw 2 and 4 respectively which may be axially reciprocable. Plasticizing of the core material may take place before, during, or after feeding of the skin material to the barrel 1. A multiway tap 5, in the position shown in Fig. 2 connects the two barrels and isolates both from the sprue channel 8. In another position (Figs. 3, 4, not shown) both barrels are connected to the sprue channel. Alternatively, in a second position the tap may connect one barrel to the sprue channel, the other being isolated. A further quantity of skin material may be injected after the core material. This may be done by switching back to the skin material barrel after injection of the core material. Alternatively, no switching is necessary if the tap 5 is as seen in Fig. 4 (not shown). The core material may be foamable. Numerous examples of suitable injection moulding materials are given.
