Mold for manufacturing cylindrical mirror array

The invention provides a mold for manufacturing a cylindrical mirror array. The mold comprises a male mold assembly, a female mold assembly and a runner assembly, wherein the female mold assembly comprises a box; an envelope in a cylindrical mirror shape is formed on the bottom surface of the box; the male mold assembly comprises a planar plate which serves as an upper cover plate of the box; the planar plate is matched with the box, and the edges of the planar plate and the box are tightly coupled; the runner assembly is connected with one side surface of the box; raw materials are injected into the box through the runner assembly. The mold for manufacturing the cylindrical mirror array is used for manufacturing the cylindrical mirror array by replacing a glass material with a high-light-transmittance PC (polycarbonate) material or a PMMA (polymethyl methacrylate) material, so that the process links for processing a cylindrical mirror can be reduced, good optical performance indexes can be achieved, and the
