Abstract
PURPOSE: To obtain the titled die which can provide the molded article with the desired distribution of continuously varying refractive index at the stage of the injection molding process, by providing the mold body with the means of cooling having distribution characteristic of the cooling temperature corresponding to the predetermined distribution of continuously varying refractive index.
CONSTITUTION: The grooves having parabolic cross section are shaped on the upper and lower faces of the mold bodies 1a, 1b in Z axis direction as the primary cooling means 4a, and the plural cooling tubes 5a, 5b... are drilled through in an arrangement along the parabola as the secondary cooling means 6a. The distribution characteristic of the cooling temperature to molten plastic material presents the lowest temperature at position Xo corresponding the vertex of parabola and shows parabolic distribution characteristic of the cooling temperature, then the solidified plastics molded article has the distribution of refractive index such as the illustrated curve in the Figure.
