PURPOSE:To obtain the molded object with high accuracy, while the distribution of flowing speed may be made uniform and the deviation of weld or stress is removed by making the flowing path of the molten resin which passes through a runner and is fed in a cavity single. CONSTITUTION:When molten resin is fed into a cavity 22 from first and second runners 23, 24, a spherical valve disc 27 is brought in contact with contacting parts 31a, 41a, whereby while the passage of molten resin between a movable mold 21b and the spherical valve disc 27 is suppressed, said resin is caused to pass between the mold 21a of stational side and the spherical valve disc 27, and while the resin is squeezed at a runner 24R between bearing members 31, 41 and the mold 21a of stationary side, the resin is guided in one direction. |
