Water-Cooled Copper Mould: Two Halves with Cast-In Pipes, in a Trunnion Yoke (Peirce, US 2,048,024, 1936)
A mould for metals that conduct heat well: two thick copper blocks, each cast round a grid of copper pipes that carry cooling water. They are bolted face to face, so the cavity can be machined accurately, and carried in a steel yoke on hollow trunnions that feed the water. A latched gate closes the bottom. The casting can be dumped out of the top by turning the yoke, or out of the bottom by opening the gate.
Result: a water-cooled copper mould that freezes the metal fast and can be taken apart, machined and cleaned.

Cast the two halves round their pipes
Cast the two halves round their pipes
For each half, assemble copper pipes into a grid: a horizontal inlet pipe at the bottom, an outlet pipe at the top, and several vertical pipes joining them. Any steam formed in casting then rises to the outlet. Cast a block of copper of about the mould's shape over the grid. Ours: copper ingot melted in a crucible furnace. Not given: sizes, the copper grade.

Machine the cavity
Machine the cavity
Machine the inner faces of the two halves to form the casting space, accurately. The recesses can be cut to different depths, for example five-eighths of the casting's width in one half and three-eighths in the other. Bolt the halves together face to face.

Make the yoke and the bottom gate
Make the yoke and the bottom gate
Cast a U-shaped steel yoke in one piece: two hollow ends with trunnions in line, joined by struts that carry the mould, bolted on. Make a bottom gate machined to fit tight under the mould, with its own cooling passage. Mount it on a gate arm keyed to a shaft across the yoke, its wedge end pinned in a V slot so the gate rocks to align. Add a lever on the shaft and a latch on an eccentric with a handle, to lock the gate up tight. Ours: steel ingot for the yoke casting.

Pipe the cooling water
Pipe the cooling water
Bring water in through a pipe in the centre of one trunnion into the hollow yoke end, and from there by fitted pipes to the inlets of both halves and by a flexible metal hose to the gate. Lead the outlets to the other hollow end, and out through a pipe in the centre of the other trunnion, so the water keeps flowing while the yoke turns. Not given: the hose, the flow.

Cast and dump a cake
Cast and dump a cake
Latch the gate shut, coat the cavity with a mould dressing such as graphite, circulate the water and fill the mould with molten metal. When the cake has cooled, turn the yoke on its trunnions so it slides out of the top, or trip the latch so the gate swings back and it drops out of the bottom. Unbolt the halves now and then to clean them or machine their faces true again.
