PROBLEM TO BE SOLVED: To provide a mold for injection molding having a gate prevented from being clogged with resin. SOLUTION: The mold for injection molding having a cavity 14 and having a fixed side mold 2 and a movable side mold 3 comprises: a runner 26 having a trunk part 26a, a vertical runner 26b and the gate 26c arranged directly under a sprue 7b of a resin channel. The trunk part 26a has a partition plate 27 for vertically splitting the resin channel. Since a molten resin introduced from the sprue 7b and brought into contact with the plate 27 brings about a turbulent flow, the high-temperature resin of this flow is mixed with the resin starting to be cooled and solidified in the runner 26 and again stated to be molten, it can prevent the gate from being clogged.
