MOLD PRESS MOLDING APPARATUS, AND METHOD OF MANUFACTURING MOLDED PRODUCT

Title:

MOLD PRESS MOLDING APPARATUS, AND METHOD OF MANUFACTURING MOLDED PRODUCT

Document Type and Number:

Japanese Patent JP2006265060

Kind Code:

A

Abstract:

To obtain a molded product such as a high precision optical element (e.g. glass lens) extremely high in eccentricity precision, thickness precision, and surface precision by effectively suppressing mainly the tilting of an upper mold and a lower mold when press molding a molding raw material disposed inside a mold by pressing the mold.

In this invention, a press member 1 that is linked to a drive means and applies a press load to a mold M, a load transmission member 2 that is swingably in contact against the press member 1 and transmits the press load by being pressed by the press member 1, and an interposing member 40 that presses the mold M while keeping the contact with the load transmission member 2 are used, and the mold M is pressed by the press member 1 via the load transmission member 2 and the interposing member 40.
