[0028] The technical scheme of the utility model is specifically described below in combination with the drawings.

[0029] The hot-pressing mold for bonding the notebook pivot can be used for bonding computer shells and corresponding pivots of different specifications, and can ensure the tightness of the bonding of the pivot and the shell and avoid affecting the appearance of the aluminum shell.

[0030] Specifically, the hot-pressing mold comprises an upper mold A and a lower mold B arranged in an up-down manner; wherein the shell and the pivot to be pressed together are placed on the lower mold B, and the upper mold A moves towards the lower mold B to perform pressing, as shown in Figure 3 The surface of the upper mold A facing the lower mold B is provided with a protrusion; it can be a hot-pressing silica gel layer, which can be tightly attached to the surface of the shell when the upper mold and the lower mold are pressed together; please refer to Figure 8The product 1' to be pressed in this utility model includes a shell 10', and a corresponding shell skeleton 11' is provided on one surface of the shell 10'. Pivots 12' need to be glued to both ends on one side of the same surface. In the actual product, the pivots 12' are glued to the shell 10' by a pivot mounting bracket, that is, glue is applied between the pivot mounting bracket and the shell, and then the product is placed on the lower mold B.

[0031] Please see Figure 2 , Figures 4 to 7 The lower mold includes a lower fixing plate 1 and a lower contouring component 2 detachably disposed above the lower fixing plate 1; the lower contouring component 2 includes a main body plate 20 for placing the laptop shell and a splicing plate 21 that can be freely spliced ​​at a set position on the main body plate 20. Figure 5 The positional relationship between the splicing panel 21 and the main body panel 20 shown is as follows: Figure 8 In other embodiments designed for the product, the pivot 12' is bonded to other positions of the outer shell 10', in which case the positions of the splicing plate 21 and the main body plate can be adjusted accordingly.

[0032] Specifically, such as Figure 6 As shown, the splicing panel 21 includes a splicing body, which has a floating groove 210. A floating block 22 is placed in the floating groove 210. To achieve the floating function, a positioning post 211 and a lower buffer blind hole 212 are provided at the bottom of the floating groove 210. A corresponding positioning hole 220 and an upper buffer blind hole are provided on the floating block 22. Figure 7 (Not shown in the image); When the floating block 22 is positioned within the floating groove 21, the two ends of the buffer spring are respectively positioned within the upper and lower buffer blind holes, while the positioning post 211 is positioned within the positioning hole 220. The cooperation between the positioning post 211 and the positioning hole 220 enables the floating block 22 to stably float within the floating groove.

[0033] Furthermore, the floating block 22 is used to place the mounting bracket of the laptop pivot. In order to increase the versatility of the splicing plate 21, a positioning insert 213 is detachably provided on the end face of the positioning column 211. The positioning insert 213 is adapted to the positioning through hole of the mounting bracket of the laptop pivot. By replacing the corresponding positioning insert 213, the splicing plate 21 can be adapted to different pivot mounting brackets.

[0034] Furthermore, such as Figure 4As shown, the upper surface of the lower fixed plate 1 is provided with a plurality of support blocks 10, so that the main plate 20 can be detachably arranged on the support blocks 10. The support blocks 10 can be arranged around the lower fixed plate 1 or in the central area, which is used to support the main plate 20. The main plate 20 is provided with a profiled protrusion 200, so that the shell 10' placed thereon can be stably placed. The splicing plate 21 can be detachably spliced on the main plate 20, as shown in Figure 6 As shown, the splicing plate 21 is clamped or bolted on one side of the main plate 20 by arranging buckles or threaded holes on the extension part of the splicing plate 21. In one embodiment, the main plate 20 is in a rectangular shape, and the splicing plate 21 is spliced on one long side of the main plate 20, which is visually protruding outside the main plate 20. Threaded holes can be arranged on the splicing position commonly used on the main plate 20. In order to further ensure that the shell 10' is uniformly stressed when the upper die A is pressed down, the blank position after the splicing plate and the main plate are spliced can be supplemented by additionally designing auxiliary splicing plates matched with different splicing positions. The splicing method of the auxiliary splicing plate can be the same as that of the splicing plate, which will not be described here.

[0035] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 , Figure 5 , the upper surface of the main plate 20 is formed with a plurality of positioning guide columns 201 in addition to the profiled protrusion 200 matched with the inner skeleton of the notebook shell. Meanwhile, the periphery of the main plate 20 is provided with a plurality of abutting assemblies 3. Specifically, the abutting assembly 3 includes a plurality of abutting blocks 30, which stably place the shell through the abutting blocks 30.

[0036] In order to adapt to different sizes of the shell, the abutting assembly 3 located on at least one side of the main plate further includes an abutting cylinder 31 and an abutting slide rail 32. The abutting block 30 is arranged on the corresponding abutting slide rail 32, and the abutting cylinder 31 drives the abutting block 30 to slide along the abutting slide rail 32, thereby adjusting the position of the corresponding abutting block 30.

[0037] In other embodiments, the lower fixed plate 2 is provided with a plurality of jacking assemblies 4. The jacking assembly 4 includes a first jacking unit for jacking the mounting frame of the notebook pivot and a second jacking unit for jacking the notebook shell. Specifically, the first jacking unit and the second jacking unit include a jacking cylinder 400 and a jacking rod 401. The jacking rod 401 of the first jacking unit penetrates the splicing plate 21 and the floating block 22, and the jacking rod 401 of the second jacking unit penetrates the main plate 20. Of course, for different positions of the splicing plate, the first jacking unit is correspondingly arranged.

[0038] The above only describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made by using the content of the present application specification and drawings, is also included in the patent protection scope of the present application.
