Abstract: A mold for molding a glass product is provided. The mold includes a lower mold and an upper mold. The lower mold includes a lower pressing surface. The upper mold includes an upper pressing surface. The upper pressing surface includes a plurality of upper molding surfaces and an upper mold closing surface connecting the plurality of upper molding surfaces. The lower pressing surface includes a plurality of lower molding surfaces and a lower mold closing surface for connecting the plurality of lower molding surfaces. The upper mold closing surface and/or the lower mold closing surface include at least two mold closing regions sequentially arranged from center to outside. The at least two mold closing regions have surface roughnesses increasing from center to outside. The disclosure achieves the technical effect of even filling, synchronous demoulding, and reduced error between mold cavities.

Abstract: 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.

Abstract: The present disclosure relates to a technical field of optics, and discloses a glass product forming mold. The glass product forming mold comprising: a lower mold comprising a first surface and a upper mold comprising a second surface; the lower mold includes a first forming portion for forming the glass product, the upper mold includes a second forming portion corresponding to the first forming portion; the lower mold includes at least one first effluence portion, the first effluence portion is formed by bending from the first surface and is located on the same side of the first surface as the first forming portion, and/or, the upper mold includes at least one second effluence portion, the second effluence portion is formed by bending from the second surface and is located on the same side of the second surface as the second forming portion. The mold is easy to demould and the product consistency is good.

Abstract: A molding mold of a glass product includes a lower mold defining a first molding surface and an upper mold defining a second molding surface. The first molding surface is disposed on one side of the lower mold close to the upper mold. The second molding surface is opposite to the first molding surface. The first molding surface includes a first molding portion and a first fixing portion disposed on a periphery of the first molding portion. The second molding surface includes a second molding portion and a second fixing portion disposed on a periphery of the second molding portion. The lower mold includes a support portion extending from the first fixing portion of the lower mold toward the second fixing portion. The support portion abuts against the second fixing portion, so that the first molding portion and the second molding portion form a molding chamber.
