PROBLEM TO BE SOLVED: To provide a die-casting metal mold capable of preventing the change of an amount of projection from a cavity wall surface of an extrusion pin when reattaching an extrusion board to a fixed mold.SOLUTION: A die-casting metal mold 1 includes a fixed mold 10 mounted on a fixed platen 2, and a movable mold 20 mounted on a movable platen and defining a mold cavity 3 together with the fixed mold 10. The fixed mold 10 is provided with an extrusion board 30 to which an extrusion pin 34 and a return pin 33 are attached, a spring 39 energizing the extrusion board 30, a pressing plate 35 pressing the spring 39, and a sleeve member 36 guiding a movement of the extrusion board, and when opening the mold, a casting is separated from a cavity wall surface 12A with the extrusion pin 34. The pressing plate 35 compresses the spring 39 and moves by mounting the fixed mold 10 on the fixed platen 2, and a rear face 11D of the fixed mold 10 and a rear face 35B of the pressing plate 35 are configured to be on the same plane. |
