PROBLEM TO BE SOLVED: To provide an injection molding mold which solves a problem of bad appearance such as weld and the like and a problem of bad appearance such as shrinkage and the like, each problem tending to occur in a mold under an opposite temperature condition and to enhance a yield of a molded item. SOLUTION: In an injection molding mold in which a movable mold 2 is mounted closably and openably on a fixed mold 1, the fixed mold 1 is separated into a fix side mold member 11 secured to a fixed platen of the injection molding machine and a cavity side mold member 12 facing the cavity 3, the cavity side mold member 12 being spacable and contactable with respect to the fix side mold member 11 by closing and opening operations of the movable mold 2, the temperature of the cavity side mold member 12 being determined to be higher than that of the fix side mold member 11. The cavity side mold member 12 is composed of a cavity forming member 13 facing the cavity 3 and a connecting member 14 connected to the cavity forming member 13 via a heat insulation member 15.
