<p>PROBLEM TO BE SOLVED: To provide an injection molding method capable of suppressing the generation of bubbles and molding a resin molded body having suitable strength.SOLUTION: In the injection molding method, a resin molded body 10 having a thin part 31 and a thick part 33 is molded using a die 40 having an inflow port 41A, a first molding space 47 provided continuously at the inflow port 41 and forming the thin part 31 of a resin 30, and a second molding space 49 provided continuously at the downstream side of the first molding space 47 and molding the thick part 33 of the resin 30 whose thickness is thicker than the thin part 31 in the resin 30. Regarding the injection molding method, in a molding step where the resin 30 is filled into the first molding space 47 and the second molding space 49 to mold the resin molded body 10, the resin 30 filled into the first molding space 47 is not solidified till the resin 30 filled into the second molding space 49 is solidified.</p> |
