20240059599 · 2024-02-22 ·

A mold for molding a glass product is provided. The mold includes a first pressing mold having a first surface and a second pressing mold having a second surface. The first surface is located on a side of the first pressing mold. The second surface is located on a side of the second pressing mold. The first pressing mold includes a first molding portion formed by bending from the first surface. The second pressing mold includes a second molding portion and is formed by bending from the second surface. The first pressing mold further includes a plurality of first hydraulic resistance portions that are spaced apart from each other, close to an outer edge of the first pressing mold, and protrude from the first surface. The disclosure achieves a technical effect of increasing a peripheral molding pressure of the mold and improving yield of products.

A molding mold and a method for manufacturing a glass lens is provided. The molding mold includes a first pressing mold having a first surface and a second pressing mold having a second surface. The first surface is provided with a plurality of first molding portions for molding glass lenses and the second surface is provided with a plurality of second molding portions for molding glass lenses. The first pressing mold includes first flow baffles, close to a peripheral area of the first pressing mold, and protrude from the first surface towards the second pressing mold. The first flow baffle is configured to restrict glass flow during a hot-pressing process, so as to balance molding pressure of the molding mold from a center to the peripheral area. The disclosure achieves a technical effect of increasing a peripheral molding pressure of the mold and improving yield of products.
