Embodiment Construction

[0027] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 and figure 2 As shown, a ceramic mold for bending and forming a glass plate according to the present invention includes a ceramic punch 1, a cover plate 2 and a plurality of electric heating elements 3, and the ceramic punch 1 is fixed on the cover plate 2 The lower surface of the ceramic punch 1 has a side wall 11 and a bottom wall 12, the electric heating element 3 is arranged in the bottom wall 12, and the outer surface of the bottom wall 12 has a The concave surface matches the convex molding surface. The cover plate 2, the side wall 11 and the bottom wall 12 enclose a vacuum chamber 13. In the bottom wall 12, there are also a plurality of holes that pass through the bottom wall 12 and are connected to the bottom wall 12. The vacuum hole 14 that the vacuum chamber 13 communicates; the cover plate 2 is used to fix the cerami...

Abstract

The invention relates to the technical field of glass forming, particularly to glass plate bending equipment and provides a glass plate bending ceramic die. The glass plate bending ceramic die comprises a ceramic terrace die, a cover plate and a plurality of electric heating elements, wherein the ceramic terrace die comprises a side wall and a bottom wall; the glass plate bending ceramic die also comprises at least three hanging devices, the outer surface of the side wall is provided with at least three positioning blind holes, every hanging mechanism comprises a fixing device and an inserting device, the top end of the fixing device is fixedly connected to the lower surface of the cover plate, the outer end of the inserting device is fixed onto the fixing device, and the inner end of the inserting device can be inserted into the corresponding positioning blind hole. The glass plate bending ceramic die can avoid the problems of expansion, breakage and the like in local connected parts during application and reduce fluctuation of low glass profiles to produce finished glass plates with higher profile quality and meanwhile to ensure the bending quality of circumferential edges which are higher in forming difficulty.

Description

[0001] Technical field: [0002] The invention relates to the technical field of glass forming, in particular to equipment for bending glass plates, and specifically provides a ceramic mold for bending and forming glass plates. [0003] Background technique: [0004] The windshield on the car is a glass product that has been bent and formed. Usually, ordinary flat glass is bent and formed into a specific shape and curvature. It is then bent into the desired shape using a male mold having a convex forming surface that mates with the concave surface of the final formed glass sheet, and a female mold. In the prior art, there are convex molds made of metal materials, for example, patent CN101720308A discloses a glass bending process, which includes providing a positively heated convex mold with a forming surface comprising one or more Holes, the punch material is aluminum or stainless steel, due to the large thermal expansion coefficient of the metal material, the convex molding s...
