Problems solved by technology

[0002] The existing display includes a panel and a backlight module. The backlight module is composed of an optical film, a light guide plate, a backlight unit, and a backplane. The role of components, the technical requirements for the backplane include dimensional tolerances, flatness, curvature and other indicators, especially for large-size LED backplanes, which are more difficult to manufacture, especially when the convex hull of the product is relatively high ( Generally more than 10mm), it is easy to crack, and the convex hull height of a large-sized backplane, such as a 42-inch LED backplane mold, is generally 12mm, and the yield of the convex hull punched out by the existing mold and production method is low

Embodiment 1

[0019] figure 1 It is a structural diagram of a stamping die for display back panel convex provided by Embodiment 1 of the present invention.

[0020] A stamping die for convex hull of a display backplane, comprising: a punch 1 and a die 2 located below the punch 1, the center of the die 2 is recessed downward to form a hollow cavity 3, the The punch 1 includes a fixed punch portion 4 and a movable punch portion 5, the fixed punch portion 4 includes a first core portion 6 and a first cavity 8, and the movable punch portion 5 includes a movable core portion 7 and a movable support part 10, the movable support part 10 is located in the first cavity 8 and closely fits with the first cavity 8, the first core part 6 and the movable core part 7 A core is formed, and the shape of the core and the shape of the cavity 3 are the same as that of the convex hull.

[0021] In this embodiment, the present invention decomposes the stamping process into two stampings by fixing the punch hea...

Embodiment 2

[0029] Such as image 3 As shown, when the stamping die is not working, the movable punch part 5 is located in the first cavity 8, and the fixed punch part 4 is first in contact with the display backplane during the stamping process of the punch 1, When the fixed punch part 4 enters the cavity 3 completely, the screw rod 12 cooperates with the threaded structure 11 to make the movable punch part 5 move from the first cavity 8 to the The movement in the cavity 3 is used to stamp the back panel of the display for the second time. When the movable core 7 fits with the cavity 3, the movable punch 5 stops, and the stamping process is completed.

Abstract

The invention relates to the technical field of stamping dies, in particular to a stamping die of displayer back plate convex hulls. The stamping die comprises a punch and a concave die located under the punch, the center of the concave die concaves downwards to form a hollow cavity, the punch comprises a fixed punch portion and a movable punch portion, through the fixed punch portion and the movable punch portion, the stamping process is divided into two sub stamping processes, the convex hulls are formed step by step, stress of sectional materials at the root portions of the convex hulls is reduced, and yield of the convex hulls is improved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for a display back panel convex. Background technique [0002] The existing display includes a panel and a backlight module. The backlight module is composed of an optical film, a light guide plate, a backlight unit, and a backplane. The role of components, the technical requirements for the backplane include dimensional tolerances, flatness, curvature and other indicators, especially for large-size LED backplanes, which are more difficult to manufacture, especially when the convex hull of the product is relatively high ( Generally more than 10mm), it is easy to crack, and the convex hull height of a large-sized backplane, such as a 42-inch LED backplane mold, is generally 12mm. Contents of the invention [0003] The object of the present invention is to provide a stamping die for convex hull of the display backplane, which improves the yield of the convex...
