A hot bending mold for automobile printing glass
A technology for glass and automobiles, which is applied in the field of hot-bending molds for printed automotive glass. It can solve the problems of heat absorption in the local printing area and heat loss in the unprinted area, uneven molding speed of the printed glass spherical surface, and low product qualification rate, so as to reduce heat. Loss, production cost reduction, the effect of production cost reduction

Problems solved by technology
[0003] The technical problem to be solved by the present invention is that, for the existing hot bending mold, when the automotive printed glass product with large printing edge and screen area and spherical surface is hot bent, due to the defect of the mold, the local printing area absorbs more heat. In addition, the heat loss in the unprinted area is large, resulting in unsmooth printed glass spherical surface and slow forming speed, resulting in low product qualification rate and high production cost.

Abstract
The invention relates to a hot bending mold for an automotive printed glass. The hot bending mold comprises an inner mold frame (1), a pedestal (2) and support rods (3), wherein the support rods (3) are connected between the inner mold frame (1) and the pedestal (2) and are used for supporting the inner mold frame (1); the inner mold frame (1) is integrally in an irregular shape with a corner and comprises two horizontally-symmetrical upper corner parts (100), two horizontally-symmetrical middle corner parts (200) and two horizontally-symmetrical lower corner parts (300); a bracket is arranged between the support rods (3), and outer molds (5) for widening the middle corner parts (200) are welded at the middle corner parts (200); heat absorption fixtures (6) for reducing the heat absorption of local printing regions are arranged on the inner side below the top end of the inner mold frame (1) between the middle part between the two upper corner parts (100) and the middle part between the two lower corner parts (300). According to the hot bending mold, printed glass products are rapidly formed, the spherical surfaces of the printed glass products are smooth, the percent of pass of the products is high, and the production cost is lowered.
Description
technical field [0001] The invention relates to a hot bending mold, in particular to a hot bending mold for automobile printed glass. Background technique [0002] With the advancement of the industrial level and the improvement of people's living standards, a single flat glass can no longer meet people's needs, and the hot-bending glass with beautiful style, smooth lines and flexible use is also used more and more in construction and civil occasions. It is also widely used in the field of automobiles as automobile window glass, and has become one of the necessary components of many automobiles. In the process of thermal bending of automotive glass, the automotive glass needs to be placed on the hot bending mold, but currently the automotive printed glass products with large printing edges and screen areas and spherical surfaces are in hot bending, due to the mold's Defects, the local printing area absorbs a lot of heat and the unprinted area loses a lot of heat, resulting ...
