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.
