Abstract

To provide a novel resin molding die that allows for easy removal of resin products. [Solution] A resin molding die for forming a resin product M in a cavity 2, comprising a first mold 7 and a second mold 8 that form the bottom surface portion of the cavity 2 when the mold is closed, wherein the second mold 8 is rotatably attached to the first mold 7 and has a bottom surface component 82 that constitutes a part of the bottom surface of the cavity 2, and the trajectory of the bottom surface component 82 due to the rotation of the second mold 8 passes through the cavity 2.
