1,224,765. Composite casting machines. FARMER MOLD & MACHINE WORKS Inc 26 June, 1968 [29 June, 1967], No. 30561/68. Heading B3F. [Also in Division H1] A machine for casting a connection strap over a set of battery plates comprises four stations 24, 26, 28, 30 and four battery plate carriers 40 which are indexed between the stations by rotation about a post (38) by a Geneva mechanism. The machine operates as follows. Loading station 24.-The carrier (40) (having walls 63, Fig. 9) is tilted through 45‹ and a bottom member 110 is brought up to the base of the carrier. Battery plates 12, 14 are loaded between members 79 (see Fig. 1). The members 79 are slid telescopically along the longitudinal axis of the carrier to grip the battery plates. Fluxing station 26. The battery plate carriers 40 are inverted so that the battery plate lugs 22 (see Fig. 9) point downwards. The post (38) is lowered to press the lugs 22 into foam rubber pads (119) socked in flux. Casting station 28. The fluxed plates are carried to a point above a cooled mould block 124 (Fig. 6) having two rows of cavities 127 which form straps between the battery plates. Each cavity 127 is integral with a further cavity 128, 129 for forming a post. Molten lead from a vessel 29a is fed through conduits 144a, 144b to a heated manifold 145 on each side of the mould block 124. Each cavity 127 is supplied with lead from a valve and nozzle block 148. When the cavities 127, 128, 129 are full the carrier 40 is lowered immersing the lugs in the molten lead. In addition to coolant passages 141a, 142a the mould block 124 has a heater 139 and is thermostatically controlled. To remove the cast battery parts from the mould block ejectors 130, 131 are actuated. The finished articles are unloaded at a station 30 where the gripping members 76 are telescopically extended. |
