DETAILED DESCRIPTION

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figures 1 to 4 As shown, the embodiment of the utility model includes a bottom plate 1, a lower template 3 is fixed to the top of the bottom plate 1 through a pressure block locking assembly 2, a lower mold base 4 is arranged on the top of the lower template 3, a lower mold cavity 402 is arranged on the top of the lower mold base 4, and the shape of the lower mold cavity 402 fits the surface shape of the large protective surface 17; the top of the lower template 3 is connected to an upper template 8 through a guide column assembly 7, an upper mold base 9 is arranged at the bottom of the upper template 8, an upper mold cavity 902 is arranged at the bottom of the upper mold base 9, and a cavity 903 is arranged on the top, and slide rails 904 are arranged on both sides of the cavity 903, and a mold core 10 that passes through the upper mold cavity 902 is slidably connected to the slide rails 904 through sliders 905. A spring component three 13 is connected between the top of the mold core 10 and the upper mold plate 8; the interior of the mold core 10 is hollow, and a plurality of anti-deformation claws 11 are connected thereto through a spring component one 1101, which correspond one to one to the outer protrusions on the inner protective surface 15 and the large protective surface 17; a frustum 12 is connected to the top of the mold core 10 through a spring component two 1201, and the inclined surface of the frustum 12 fits with the anti-deformation claws 11; a riveting block 14 is provided at the bottom of the mold core 10, and the surface shape of the riveting block 14 is consistent with the inner surface shape of the corresponding inner protective surface 15; a cylinder 6 is provided at the top of the base plate 1 through a mounting frame 5, and the output end of the cylinder 6 is transmission-connected to the upper mold plate 8.

[0018] Preferably, positioning pins 401 are provided on both sides of the top of the lower die base 4, and corresponding positioning holes 901 are provided on both sides of the bottom of the upper die base 9, which are used to position and connect the upper die base 4 and the lower die base 9; spring component 1 1101 and spring component 2 1201 are both composed of a spring and a guide rod, so that the anti-deformation claw 11 and the frustum 13 can slide and rebound.

[0019] like Figure 4 and 5 As shown, the lock shell 16 is first inserted into the inner protective surface 15, and then the large protective surface 17 is placed on the surface of the inner protective surface, and then the large protective surface 17 is placed in the lower mold cavity 402. At this time, the cylinder 6 is started to drive the upper mold plate 8 and its upper parts to press down. During the pressing process, the top of the lock shell 16 first presses against the bottom of the truncated cone 12. At this time, the truncated cone 12 moves upward, thereby pushing the anti-deformation claw 11 to move outward and extend out of the mold core 10. After the riveting block 14 fits the inner protective surface 15, the end of the anti-deformation claw 11 It also fits the corresponding external protrusion on the inner protective surface 15 to prevent it from being deformed during the riveting process; then the upper mold base 9 continues to press down, and the mold core 10 slides on the slide rail 904 through the slider 905. When the upper mold cavity 902 presses the anti-dropout buckle piece 1701 on the top of the large protective surface 17, since the side surface of the upper mold cavity 902 is an arc surface, the anti-dropout buckle piece 1701 is squeezed and bent downward to buckle the inner protective surface 15; until the end faces of the upper mold base 9 and the lower mold base 4 are fitted together, the riveting process is completed.
