[Means to solve the problem]
In order to solve the above problems, in the first aspect of the present invention, claim 1 includes an upper and lower molding die in which an article to be molded is arranged, and an upper and lower body die in which the upper and lower molding die and an interval adjusting member are arranged. Provided is an optical element molding apparatus.
In claim 2 of the present invention, in addition to claim 1, the space adjusting member provides an optical element molding apparatus that keeps the upper and lower cylinders parallel.
In claim 3 of the present invention, in addition to claim 1, the coefficient of thermal expansion of the product to be molded at the molding temperature is α1, the coefficient of thermal expansion of the upper and lower molded member is α2, and the coefficient of thermal expansion of the upper and lower body member. The coefficient of thermal expansion of the spacing adjusting member is α4, the maximum thickness of the product to be molded is h1, the total height of the upper and lower molding molds at the position where the product to be molded has the maximum thickness is h2, and the total height of the upper and lower body molds. When it is h3,
Height of interval adjusting member> (h1 x α1 + h2 x α2-h3 x α3) / α4
Provided is an optical element molding apparatus characterized in that the above relationship is satisfied.
