Stamping die of back plate convex hull

Abstract

The invention provides a stamping die of a back plate convex hull. The stamping die comprises a bottom die, wherein guide columns are mounted at four corners of the upper end surface of the bottom die, a pressing plate is arranged on the upper side of the bottom die, and the upper ends of the guide columns penetrate through the pressing plate; a ball groove is formed in the upper end surface of the bottom die, a hemispherical cover is formed in the ball groove, positioning grooves are formed in the left side and the right side of the inner surface of the ball groove, a first threaded blind holes are formed in the lower end surface of the interior of the positioning grooves, positioning plates are fixed on the left side and the right side of the outer surface of the hemispherical cover, thepositioning plates are arranged in the positioning grooves, countersunk head holes are formed in the upper end surfaces of the positioning plates, inner hexagonal bolts are formed in the countersunkhead holes, a stamping rod is arranged in the middle of the lower end surface of the pressing plate, a hemispherical head is arranged on the lower end of the stamping rod, a second threaded blind holeis formed in the middle position of the upper end surface of the hemispherical head, and a stud is fixed at the lower end of the stamping rod. Compared with the prior art, the stamping die has the beneficial effects that local replacement of the worn part is realized, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a stamping die for a convex hull of a backboard, which belongs to the field of backboard processing equipment. Background technique [0002] The 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 backplane, as the main supporting mechanism of the entire backlight module, mainly plays a role in protecting the optical components in the display. , At present, the structure of the mold used to process the convex hull of the back plate is fixed, resulting in the structure of the mold used for stamping the convex hull being worn and needs to be replaced as a whole, and the maintenance cost is high. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a stamping die for the convexity of the backplane, so as to solve the problem that the structure o...
