Surface shape regulated flow injection molding lens preparation device

The invention discloses a surface shape regulated flow injection molding lens preparation device which comprises a mold and a planar substrate arranged below the mold, wherein the mold comprises a fluid inlet and a fluid outlet. The device is characterized in that a deformable working face is formed inside the mold; the working face and the substrate form a cavity of a lens shape in an encircling way; a displacement part for controlling the surface shape of the working face is arranged on the working face; and the working face and the displacement part are connected by virtue of a linked part. According to the surface shape regulated flow injection molding lens preparation device disclosed by the invention, the deformable working face is formed in the mold, and the surface shape of the working face is regulated by adopting the displacement part, so that the surface shape of the working face is regulated into the lens surface shape needing to be machined; the device has the advantages of convenience in processing and accurate surface shape.
