Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a mold for preparing a rubber frame. Background Art

[0002] With the development of liquid crystal display technology, liquid crystal displays have the advantages of being light, thin, and low in power consumption. Liquid crystal displays have become a widely used display device. Liquid crystal displays usually include a display panel, a backlight module, a rubber frame, a front shell, and a circuit board. The display panel and the backlight module are accommodated and fixed by the rubber frame, and the rubber frame is generally a hollow frame structure.

[0003] A rubber frame mold disclosed in the existing publication number CN218019910U includes: a base plate, a template, a rear mold base, a rear mold core, two first sliders and two second sliders. Four first through holes are opened on the bottom side wall of the molding groove, and each first through hole is respectively located at the four corners of the bottom of the molding groove. An injection molding insert is arranged on the second end of the fixed column, and the second end of the fixed column passes through the second through hole and the first through hole in sequence and is located in the molding groove. In this way, after the rubber frame is obtained by injection molding in the molding groove, when the mold is opened, the rear mold core can move upward under the action of a spring, thereby separating the injection molding insert from the corners of the rubber frame, making it easy to separate the rubber frame from the mold, and avoiding the four corners of the rubber frame from being deformed due to a large tensile force.

[0004] The mold core of the prior art is an integrated structure, and the stopper is installed in the mold core. The stopper is easy to fall off. Therefore, we propose a mold for preparing a rubber frame. Utility Model Content
