<p>The problem addressed by the invention is to keep a vertical injection molding machine from rising with the injection-filling of the molten resin even when same is performed at high speed. The vertical injection molding machine is configured so as to satisfy the mathematical expression (m+M)/2 > m + m×V/t/9.8 when: a pusher plate (6), which is advanced or retracted when a molding is molded by operating the vertical injection molding machine, and a member held integrally on the pusher plate (6) are the moving bodies, and the total weight thereof is the moving body weight m (kg); a front plate (5), which does not move when a molding is molded by operating the vertical injection molding machine, and a member held integrally on the front plate (5) are the stationary bodies, and the total weight thereof is the stationary body weight M (kg); the acceleration time for the injection screw when a molding is molded by operating the vertical injection molding machine is t (s); and the velocity after the acceleration time t (s) for the injection screw when a molding is molded by operating the vertical injection molding machine is V (m/s).</p> |
