Embodiment Construction

[0024] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] In actual production, the glass plate that is generally subjected to secondary baking and bending has four sides, of which there is a pair of sides that are symmetrical in the center and equal in length; among the other pair of sides, the relatively long one is called the "big head side", and the relatively short one is called the "big head side". Known as the "small head edge", the molds used for post-bending this type of glass sheet also have a roughly similar shape. Similarly, the side on the mold corresponding to the "big side" of the supporting glass plate is also called the big side, and the side corresponding to the "small side" of the supporting glass plate is called the small side.

[0026] Such as figure 1 Shown in the first embodiment of the present invention, the automotive glass secondary molding baking mold shown in it includes a ba...

Abstract

The invention relates to the technical field of baking, bending and forming of automobile glass and particularly relates to a secondary forming baking and bending die for automobile glass. The baking and bending die comprises a base, a first forming frame, a second forming frame and a reset mechanism. The secondary forming baking and bending die of the automobile glass, disclosed by the invention, can enable the baking and bending die to realize rapid reset by improving the reset mechanism, improve the reset speed, save the time of reset operation, further avoid the defect that the die is easy to deform when the reset operation is respectively performed on the two sides of the forming frames, meet the requirements of high-efficient reset, improve the piece feeding speed of a baking and bending process step, and improve the production efficiency and the quality of a baked and bent product.

Description

Technical field: [0001] The invention relates to the technical field of baking and bending of automobile glass, in particular to a baking and bending mold for secondary molding of automobile glass. Background technique: [0002] With the development of automotive glass technology, in order to avoid the disadvantages of ruffles caused by the excessive local deformation of the glass plate caused by the traditional one-time forming and bending mold, and to improve the optical performance and appearance quality of the glass plate, the secondary forming and bending mold are more and more widely used. There are two working modes of secondary molding baking and bending molds: 1. In the baking and bending furnace, the mold frame used for preforming the glass plate is fixed, and the mold frame used for the final forming of the glass plate is lifted by external force Complete the preformed glass plate; 2. In the bending furnace, the mold frame used for the final forming of the glass ...
