Description

Technical Field

[0001] The utility model belongs to the technical field of compression molds, and in particular relates to a compression mold for a glass optical element blank. Background Art

[0002] A molding die is required in the production process of glass optical component blanks. The molding die includes an upper die and a lower die. When the upper die and the lower die extrude the optical component blank, the air between the upper die and the lower die cannot be discharged, which easily interferes with the production of the optical component blank.

[0003] In the Chinese utility model patent with patent number CN201921480989.5, entitled A Glass Optical Component Blank Molding Die, when the upper mold core contacts the material, the spring will be compressed. After being compressed, the spring will contract. When the spring contracts, the pressure between the upper mold core and the lower mold core will decrease, making it easier for the air inside the material to be discharged. However, this will still cause air to exist between the upper mold and the lower mold, affecting the production of the optical component blank and reducing the production efficiency of the optical component blank.
