Heating field device of molding three-dimensional continuous glass molding device

Abstract

The invention provides a heating field device of a molding three-dimensional continuous glass molding device. The heating field device consists of a graphite heating block and a base which are integrally molded by a material with good heat conductivity, wherein the heating block has a proper number of groove holes which are tightly combined with heating elements to form a heating field; a bearingplate made of a porous ceramic material is arranged between the heating block and the base; the heating block is fixed on the base through a detachable element; and the base is fixed in a preset position of a molding device through a detachable element. As the heating field has good heat conductivity and temperature uniformity, a molded three-dimensional glass product is small in internal stress and high in molding pass percent, and the precision of sizes of products can be ensured.

Description

technical field [0001] The invention relates to the technical field of a heating thermal field device, in particular to a heating thermal field device for molding a three-dimensional glass continuous molding device. Background technique [0002] Nowadays, because of the high light transmission properties of glass, display devices (such as mobile phones, watches and other electronic products) often choose it as the shell of the window part. You can see that the surface of handheld electronic products is usually provided with a glass casing to protect the display module inside the product. At present, most of the glass casings are in the shape of a flat plate, so a seam will be formed on the upper surface of the electronic product. Furthermore, because a certain width of the mechanism must be reserved around the electronic product to hold the flat glass, the top surface of the electronic product cannot be fully utilized. Therefore, three-dimensional or curved glass has been ...

AI Technical Summary

Problems solved by technology

[0005] However, in the aforementioned patent, since the heating block is integrally formed of a metal material with good heat conduction, and the heating block is fixed on the base with a detachable element, the heat conduction of general metals is still not fast enough, so that the heat conduction of the thermal field formed by the heating block and the heating element and temperature uniformity still have room for improvement

Furthermore, since the heat of the heating block is directly transmitted to the metal base, the base may be deformed due to high temperature, and the pressure bearing capacity is insufficient, which cannot ensure the accuracy of the molded three-dimensional glass product size.
