PROBLEM TO BE SOLVED: To effectively prevent a molding fault of a molding by simply controlling a charging amount of a material to be charged in each cavity. SOLUTION: The mold 10 for injection molding comprises first and second molds 11, 12. The mold 12 has secondary cavities 18, 19 formed therein, and nozzles 26A, 27A of cylinders 26, 27 disposed oppositely to the cavities 18, 19. The cylinders 26, 27 are provided to pressure charge a material from an injecting unit 21 in the cavities 18, 19 in such a manner that charging amounts of the cavities 18, 19 are independently controlled at respective cavities 18, 19 by pressurizing units 40, 41 connected to a controller.
