The invention provides a curved glass forming mold, which comprises an upper mold and a lower mold located below the upper mold, wherein a cavity used for machining a product is formed between the upper mold and the lower mold, positioning plates are oppositely arranged on the two sides of the lower end of the upper mold, the axes, in the length direction, of the positioning plates are parallel tothe moving direction of the upper mold, a first cavity is formed between the two positioning plates, and the distance between the two positioning plates corresponds to the size of a product; and an air suction column is arranged on the lower portion of the lower mold and internally provided with a vertical air suction channel. According to the invention, the positioning plates are oppositely arranged at the lower end of the upper mold, the two positioning plates and the two ends of the product are positioned after mold assembly, the product in the cavity is subjected to heat suction through the air suction channel of the lower moldy, and the plate-shaped product is subjected to heat suction into a curved surface product through heat suction force, so that the product is prevented from deviating in the hot bending process, mold marks and indentations are prevented from being generated on the surface of the product, the grinding-free effect is achieved, the production cost is reduced, and the product machining quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of curved glass manufacturing, in particular to a curved glass forming mold and a curved glass screen manufacturing system. Background technique [0002] As people have higher and higher requirements for the appearance of automobile interiors, the application of curved glass products in screen systems has become more and more extensive, and the requirements for the design and molding process of curved glass molds have also become higher and higher; The core process of glass products - hot bending forming mold, due to the particularity of the process, after hot bending, the convex and concave surface of the curved glass will have a certain degree of mold marks and indentations, which need to be removed by the subsequent sweeping process, but sweeping It is difficult to remove the mold marks and indentations of such large curved and high-height curved glass products, which affects the appearance and yield of t...
