AI Technical Summary
Technical Problem
Resin products manufactured using existing molds often stick to non-rotating parts of the mold, making it difficult to remove them after the mold is opened.
Method used
A mold design featuring a first mold and a second mold that form the bottom surface of the cavity, where the second mold is rotatably attached to the first mold, allowing the bottom surface component to rotate and pass through the cavity, facilitating easy removal of the resin product.
Benefits of technology
Enables easy removal of resin products by flipping up the flange surface and separating it from the mold, ensuring smooth demolding without residue.

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.
