PROBLEM TO BE SOLVED: To provide an injection molding die which prevents a flow mark as a non-conforming appearance from being generated on the peripheral part of a gate in a molded product despite the type of the mold that the gate is cut inside the die and further, has an improved degree of freedom in the structure of the die. SOLUTION: This molding die is structured in such a way that a gate (35) has an almost rectangular section and a part (37) near the gate (35), of a runner (31) is tilted in the runner ejecting direction so that the direction, facing the gate (35), of the runner (31) at the part (37) near the gate (35) is diverted to the movable half side of the die, and that the movable half-side template (17) between a parting line-side face (37a) at the part (37) near the gate (35) and the parting line (39) serves as a cutting blade (41) and the runner (31) is cut off the molded product (33) at the gate (35) by the cutting blade (41), when the runner (31) is ejected after opening the die.
