PURPOSE:To provide an injection molding method, with which high quality, comparatively large-sized, thin resin product can be molded without developing weld-marks and flow mark. CONSTITUTION:Molten resin A is distributed and supplied from the same resin feed passage 5 to a plurality of resin pouring parts 3. At the same time, the molten resin A is injection-poured from a plurality of the resin pouring parts 3 in the predetermined pouring order in the cavity 2 in a mold 1. The injection- pouring from the second order resin pouring parts 3b and 3b are performed after the arrival of the molten resin A, which is injection-poured from the first order resin pouring part 3a, to the positions of the resin pouring parts 3b and 3b. Further, when the injection-pouring from the second order resin pouring parts 3b and 3b is started, the total amount of the molten resin distributed and supplied from the resin feed passage 5 to the respective resin pouring parts 3 is increased. |
