[0010] Figure 1 This is a schematic diagram of the structure of the embodiment of the utility model in the mold closing state;

[0011] Explanation of the numbers in the figure: 1-upper template, 2-lower template, 3-upper ejector rod, 4-lower ejector rod, 5-positioning block, 6-locking nut, 7-rubber pad, 8-limit block, 9-display back panel. DETAILED DESCRIPTION

[0012] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0013] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0014] like Figure 1 As shown, a display back panel shaping mold includes an upper template 1 and a lower template 2. A plurality of upper push rods 3 for pressing the upper surface of the display back panel are arranged below the upper template 1, and a plurality of lower push rods 4 for supporting the lower surface of the display back panel are arranged above the lower template 2. The length of the upper push rods gradually increases from the middle to both sides, and the length of the lower push rods gradually decreases from the middle to both sides; positioning blocks 5 for abutting against the ends of the display back panel are arranged on both sides above the lower template. The lower ends of all upper ejector rods 3 form an upper shaping curved surface, and the upper ends of all lower ejector rods 3 also form a lower shaping arc surface. When the upper template 1 is moved downward to close the mold, the display back panel is punched and shaped by the upper and lower ejector rods, and the shaping effect is good, which improves the curved panel shape accuracy of the display back panel and improves the product quality; the positioning blocks 5 on both sides are used to block the two ends of the display back panel to ensure that the display back panel is in the middle position and improve the processing accuracy; and the use of the upper ejector rod and the lower ejector rod structure with intervals can effectively avoid the holes, protrusions, grooves and other structures that have been processed on the display back panel to avoid deformation of these structures and ensure the subsequent installation accuracy.

[0015] In this embodiment, the upper ejector and the lower ejector are both screw rods, and the lower side surface of the upper template and the upper side surface of the lower template are respectively provided with threaded holes for connecting the upper ejector and the lower ejector, and the upper ejector and the lower ejector are threadedly connected with locking nuts 6 respectively against the lower side surface of the upper template and the upper side surface of the lower template. The upper ejector and the lower ejector of the screw rod design can adjust the length as needed to adjust the curvature of the upper and lower shaping surfaces to adapt to display back panels of different board types, and have good versatility.

[0016] In this embodiment, in order to prevent the upper and lower push rods from damaging the surface of the display back panel, the lower end of the upper push rod and the upper end of the lower push rod are respectively fixedly connected with rubber pads 7.

[0017] In this embodiment, a pair of limit blocks 8 are provided between the upper and lower mold plates, which can be pressed against each other after mold closing. The limit blocks 8 can limit the extreme position of the upper mold plate when the mold is closed, thereby ensuring product safety.
