A glass product forming mold includes a first mold and a second mold opposite to the first mold, a flat glass is formed into a three-dimensional glass structure after the first mold and the second mold are molded together. The first mold includes a first molding surface, a bottom surface, a side surface connecting the first molding surface and the bottom surface, and a first inclined surface; the second mold includes a second molding surface; and the first inclined surface extends to connect to the side surface from an edge of the first molding surface along a direction away from the first molding surface and the second mold. A thermal expansion coefficient of the first mold is smaller than that of the flat glass. Before complete cooling, the three-dimensional glass structure has been separated from the first molding surface, avoiding the deformation and rupture of the three-dimensional glass structure.

A glass product forming mold includes a mold body and a plurality of ejector mechanisms disposed on the mold body at intervals. The mold body is defined a plurality of gaps surrounding separately the mold body, and each gap receives one ejector mechanism. The mold body includes a forming surface for forming a glass product, the ejector mechanism includes a first wedge configured to lift the glass product and a second wedge configured to drive the first wedge to move vertically with respect to the forming surface, and the first wedge is flush with the forming surface. After the formation of the glass product, the ejector mechanisms lift the glass product so that the glass product does not contact with the mold body, avoiding the deformation and crack of the glass product, ensuring the quality of the glass product, accelerating the cooling of the glass product.

A glass product forming mold includes a mold body and a plurality of sliding blocks slidably mounted on the mold body and facing the glass product; each of the plurality of sliding blocks includes a first inclined surface; the plurality of sliding blocks are configured to be inserted between the glass product and the mold body through the plurality of the first inclined surfaces to separate the glass product from the mold body. The sliding blocks are driven to separate the glass product from the mold body, avoiding the deformation of raw glass products resulting from the uneven heat distribution, uneven shrinkage or excessive adhesion, and the glass products will not be interfered by the mold body during the process of cooling shrinkage, which reduces the risk of cracking of the glass product.

A mold includes a mold component, a plurality of ejector pins and a stop block. The mold component has a molding surface for forming a glass product and a bottom surface disposed opposite to the molding surface. The mold component defines a plurality of passing through holes through the molding surface and the bottom surface. Each ejector pin passes movably through one corresponding through hole and is configured to separate the glass product from the mold component. The stop block for forming a stop on the ejector pins disposed on one side of the bottom surface. Separates the glass product from the mold component before the glass product is completely cooled down by using the combination of the ejector pins together with the stop block, which can make the cooling of the glass product more uniform.

Fiber bending mechanisms vary beam characteristics by deflecting or bending one or more fibers, by urging portions of one or more fibers toward a fiber shaping surface having a selectable curvature, or by selecting a fiber length that is to be urged toward the fiber shaping surface. In some examples, a fiber is secured to a flexible plate to conform to a variable curvature of the flexible plate. In other examples, a variable length of a fiber is pulled or pushed toward a fiber shaping surface, and the length of the fiber or a curvature of the flexible plate provide modification of fiber beam characteristics.
