<p>PROBLEM TO BE SOLVED: To provide a casting metallic mold that keeps the quality of a casting and also can improve maintainability of liner replacement.SOLUTION: A first liner 70 comprises a first block 73 forming the surface 53 of a cavity, and a second block 74 supporting the first block 73. The second block 74 includes a first recess 75 into which the first block 73 is fitted. Also, the second block 74 includes an edge 76 forming a portion of the surface 53 of the cavity while surrounding an inlet of the first recess 75, and a first cooling medium passage 54 provided below the first recess 75 and causing a cooling medium for cooling the first block 73 and the second block 74 themselves to flow. The replacement of the liner is performed only by removing the first block out of the second block without removing the cooling medium passage, and thereby the liner replacement is facilitated and the maintainability can be improved.</p> |
