Glass processing hot suction forming mold

Abstract

The invention discloses a glass processing hot suction forming mold which comprises a base, a supporting block is fixed to the top end of the base, a lower mold body is installed at the top end of the supporting block, an upper mold body is installed at the top end of the lower mold body, and lifting rings are fixed to the outer walls of the two sides of the lower mold body. The lower die body is provided with two sets of lifting rings, the two sets of lifting rings are of a symmetrical structure relative to the center line of the lower die body, the top of the upper die body is fixedly provided with a positioning block, the two sides of the bottom end of the positioning block are each provided with an upper bending die head, and the two sets of upper bending die heads are arranged. The two sets of upper bending die heads are of a symmetrical structure relative to the center line of the upper die body. According to the invention, the glass workpiece is rapidly cooled, the processing efficiency of the mold is improved, the dislocation and offset of the upper mold and the lower mold in the butt joint process are reduced, the glass forming quality of the mold is improved, and the mounting stability of the mold is also improved.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a heat absorption forming mold for glass processing. Background technique [0002] Curved tempered glass is a kind of curved glass that uses specific molds and equipment to heat and cool. Curved tempered glass belongs to safety glass. The special tempering process makes the surface of the glass form a uniform stress, and the interior forms a tensile stress. The surface strength of the glass can reach 4 times that of ordinary glass, high strength. Even if it is broken under the action of external force, the fragments will split evenly, without cracks, and it is not easy to hurt people. The upper cavity part of the upper cavity is heated and matched, so that the glass in the glass forming cavity is softened by heat, and is bent and formed under the influence of the pressure of the upper and lower mold bodies. At this time, the glass is in the shape of a curved surface. In...
