PROBLEM TO BE SOLVED: To suppress occurrence of a fault in a design surface in injection molding using a metallic resin.SOLUTION: A cavity 1 has a design molding surface 11 and a non-design molding surface 12 facing the design molding surface 11. A gate 2 has a first gate inner circumference surface 13 which is connected/installed in a flat state along the non-design molding surface 12 and a second gate inner circumference surface 14 facing the first gate inner circumference surface 13. A runner 3 has a first runner inner circumference surface 15 which is connected/installed in a flat state along the first gate inner circumference surface 13 and a second runner inner circumference surface 16 facing the first runner inner circumference surface 15. A separating distance B between the first gate inner circumference surface 13 and the second gate inner circumference surface 14 is shorter than a separating distance (A) between the design molding surface 11 and the non-design molding surface 12, and a separating distance C between the first runner inner circumference surface 15 and the second runner inner circumference surface 16 is longer than the separating distance B. |
