Casting mould and copper anode for producing high-purity copper

Abstract

A casting mould produces copper anodes for producing high-purity copper. The casting mould has: a first flat cavity, which is delimited by two lateral surfaces aligned in parallel with each other; two second cavities, which are fluidically connected to the first flat cavity, are arranged on different corners on a peripheral side of the first flat cavity, and extend laterally outwardly away from the first flat cavity; and a core. The core is provided centrally in a respective second cavity of the second cavities. The core sub-divides the respective second cavity at least partially into a closed annular shape in the peripheral direction.

1 . A casting mould for producing copper anodes for producing high-purity copper, the casting mould comprising:
 a first flat cavity, which is delimited by two lateral surfaces aligned in parallel with each other;   two second cavities, which are fluidically connected to the first flat cavity, are arranged on different corners on a peripheral side of the first flat cavity, and extend laterally outwardly away from the first flat cavity; and   a core, which is respectively provided centrally in a respective second cavity of the second cavities, the core sub-dividing the respective second cavity at least partially into a closed annular shape in the peripheral direction.   
     
     
         2 . The casting mould according to  claim 1 , wherein:
 the core completely sub-divides the second cavity into the closed annular shape in the peripheral direction.   
     
     
         3 . The casting mould according to  claim 1 , wherein:
 the core sub-divides the second cavity into a first portion having a closed annular shape and a second flat portion, wherein the second flat portion is arranged laterally on the first portion.   
     
     
         4 . The casting mould according to  claim 1 , wherein:
 the core is sub-divided into two partial cores by a gap.   
     
     
         5 . The casting mould according to  claim 4 , wherein:
 the gap is aligned at an angle of 0 to 45 degrees to a longitudinal central axis of the first flat cavity.   
     
     
         6 . The casting mould according to  claim 1 , wherein the core is sub-divided by a gap into two partial cores in the second cavities, and a stiffening rib of the anode is configured to be cast through the gap, wherein the stiffening rib is configured to separate the partial through openings formed by the partial cores from each other. 
     
     
         7 . The casting mould according to  claim 1 , the casting mould further comprising a plurality of cores, comprising the core, each of the cores is respectively provided centrally in a respective one of the second cavities, the respective core sub-dividing the respective second cavity at least partially into a closed annular shape in the peripheral direction. 
     
     
         8 . A casting mould for producing a copper anode for producing high-purity copper, the copper anode comprising a unitary part comprising an anode sheet and at least two holding arms, with at least one recess being in at least one of the holding arms, the casting mould comprising:
 a first flat cavity, which is delimited by two lateral surfaces aligned in parallel with each other;   two second cavities, which are fluidically connected to the first flat cavity, are arranged on different corners on a peripheral side of the first flat cavity, and extend laterally outwardly away from the first flat cavity; and   a core, which is respectively provided centrally in a respective second cavity of the second cavities, the core sub-dividing the respective second cavity at least partially into a closed annular shape in the peripheral direction.   
     
     
         9 . A method of casting a copper anode for producing high-purity copper, the copper anode comprising a unitary part comprising an anode sheet and at least two holding arms, with at least one recess being in at least one of the holding arms, the method comprising:
 casting the copper anode using a casting mould,   wherein the casting mould comprises:
 a first flat cavity, which is delimited by two lateral surfaces aligned in parallel with each other; 
 two second cavities, which are fluidically connected to the first flat cavity, are arranged on different corners on a peripheral side of the first flat cavity, and extend laterally outwardly away from the first flat cavity; and 
 a core, which is respectively provided centrally in a respective second cavity of the second cavities, the core sub-dividing the respective second cavity at least partially into a closed annular shape in the peripheral direction.
