Abstract: An anode casting machine for casting lead or lead alloy anodes used in copper electrowinning process comprising a pair of open face mold plates, means for uniting said mold plates, means for securing said mold plates in a liquid tight configuration about a hanger bar, ladle means for introducing lead or lead alloy into said mold, means for stabilizing mold temperature, means for separating said mold plates to facilitate removal of said anode, and means for transferring lead or lead alloy from a melting pot to said ladle means.
Abstract: To move the die parts and cores into position for a casting operation, a plurality of pneumatic cylinders are mounted between two parallel plates of the head of a casting machine and arranged so that they each move a different one of a plurality of die parts and cores of a die from any of several angles, exerting primarily tension on the plates rather than torsion, with each cylinder including an internal locking mechanism having locking balls that drop into holding grooves to hold the piston of the hydraulic cylinder in position with sufficient strength to withstand the pressure of the molten metal applied to the die. To inject the molten metal into the die, a nozzle spool is moved in a straight line to communicate with the interior of the die between two die parts, the molten metal being fed to an annular recess around the spool by an injector and from the annular recess through openings in the spool into a central conduit that communicates with the interior of the die.
Abstract: Support members for separable cooperating parts of a split mould are in pin-and-slot connection with one of the support members having spaced parallel projections or rollers running in a common slot in the other support member. The slot is of curvate form to determine the path of relative movement of the support members and piston and cylinder means is provided to effect this movement.
