Die for film with prism refraction function on surface

The utility model discloses a die for a film with a prism refraction function on the surface, which comprises a processing component, a movably connected film body is arranged in the processing component, a plurality of semicircular bulges are arranged on the outer wall of the film body, and the semicircular bulges have the prism refraction function. According to the utility model, the film body and the semicircular bulge are arranged, so that the film product has a stronger prism refraction function, accurate product numerical values can be obtained through multiple experiments, the prism refraction effect of the film can be optimal, the die body can be conveniently and quickly mounted and dismounted, the working efficiency of mounting is improved, and the production cost is reduced. The die body can be secondarily clamped and fixed through the attraction force between the magnet blocks, the stability of the die body during use is improved, the difficulty in carrying by workers is avoided, the working effici
