[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Reference Figures 1 to 6 The utility model proposes a shielding cover stamping die, characterized in that it includes a die base 1 and a plurality of connecting structures 2, the die base 1 includes an upper die base 11 and a lower die base 12, the edge of the upper die base 11 is provided with a plurality of guide sleeves 111, the edge of the lower die base 12 is provided with guide pillars 121 corresponding to the guide sleeves 111, the guide pillars 121 are inserted into the guide sleeves 111, the upper die base 11 and the lower die base 12 are provided with mounting platforms 13 on the opposite sides, the mounting platforms 13 are fitted and connected with a template 14, the guide pillars 121 move in the guide sleeves 111 to make the templates 14 abut against each other; each connecting structure 2 includes two connecting members 3, the two connecting members 3 are respectively arranged on the edges of the fitting surfaces of the template 14 and the mounting platform 13, the connecting members 3 are provided with plug-in columns 41 and plug-in holes 42, the plug-in columns 41 are movably provided with protrusions 511, the plug-in columns 41 of the two connecting members 3 can be inserted into each other's plug-in holes 42 at the same time and the protrusions 511 of the two connecters 3 are matched and locked.

[0028] It can be understood that the upper die base 11 and the lower die base 12 are connected by the guide column 121 and the guide sleeve 111. A platform is raised on the opposite sides of the upper die base 11 and the lower die base 12. The platform is a mounting platform 13. Each mounting platform 13 is connected to a template 14, one is a concave mold and the other is a convex mold. The two templates 14 can be pressed together to form the sheet; a plurality of connecting structures 2 are arranged on the edge of the connecting surface between the template 14 and the die base 1. Each connecting structure 2 is composed of two connecting parts 3. Each connecting part 3 has a plug-in column 41 and a plug-in hole 42 located on the side of the plug-in column 41. A protrusion 511 is protruded on the side wall of the plug-in hole 42 of the plug-in column 41. The protrusion 511 can protrude into the plug-in hole 42 or be flush with the side wall of the plug-in column 41. When When the template 14 and the two connectors 3 on the mounting platform 13 are close to each other, the plug-in posts 41 of the two can simultaneously extend into the plug-in holes 42 of each other and press the protrusions 511 so that they no longer protrude. After the plug-in is completed, the protrusions 511 protrude again, and the protrusions 511 of the two plug-in posts 41 abut against each other, and interact with the plug-in posts 41 so that the plug-in posts 41 are locked in the plug-in holes 42 and cannot be pulled out; since the mold base 1 has to be moved during each stamping process, the traditional screw connection method is very likely to loosen, causing shaking between the template 14 and the mold base 1, which will affect the production of the shielding cover and reduce the yield rate. The above-mentioned arrangement can make the connection between the template 14 and the mold base 1 more firm, and the template 14 and the mold base 1 will not loosen after multiple stampings.

[0029] Reference Figures 4 to 5 In one embodiment of the present application, the connector 3 includes a shell 4, a locking rod 5 and a spring 6. A plug-in column 41 is protruding from the shell 4. The plug-in column 41 and the inner wall of the shell 4 are configured to form a plug-in hole 42. A slide groove 43 is provided on the surface of the shell 4, and a spring cavity 44 is formed between the shell 4 and the plug-in column 41; the locking rod 5 is inserted into the slide groove 43, and its end can be partially extended into the plug-in hole 42 to form a protrusion 511; the spring 6 is arranged in the spring cavity 44, one end of the spring 6 is connected to the locking rod 5, and the other end is connected to the inner wall of the spring cavity 44.

[0030] It can be understood that the connecting member 3 is composed of a shell 4, a locking rod 5 and a spring 6. A plug-in column 41 protrudes from one side of the shell 4, and a cavity is provided on the other side. The cavity is a plug-in hole 42. At the same time, a spring cavity 44 is provided between the plug-in column 41 and the shell 4. Both side walls of the spring cavity 44 are provided with a slide groove 43. The locking rod 5 is inserted therein and a part of it extends out of the plug-in hole 42. The locking rod 5 can move along the slide groove 43. When it moves to one end of the slide groove 43, A portion of the front end of the locking rod 5 will protrude in the plug-in hole 42 to form a protrusion 511. When sliding to the other end of the slide groove 43, the protrusion 511 will become one with the side wall of the plug-in column 41 and will no longer protrude. The spring 6 is arranged in the spring cavity 44, with one end connected to the locking rod 5 and the other end connected to the inner wall of the spring cavity 44. When no external force is applied, the spring 6 will pull the locking rod 5 to one end of the slide groove 43, so that the protrusion 511 is always in a protruding state in the plug-in hole 42.

[0031] The two connectors 3 need to cooperate at the same time to achieve locking. First, the plug-in columns 41 of the two connectors 3 are aligned with the plug-in holes 42 of each other and pushed closer to each other. At this time, the front end of the plug-in column 41 contacts the protrusion 511 of the front end of the locking rod 5 and presses this part. The spring 6 is stretched, and the locking rod 5 slides to the other end of the slide groove 43. The protrusion 511 no longer protrudes. At this time, the plug-in column 41 can be fully inserted into the plug-in hole 42, and then the protrusion 511 is no longer pressed. The spring 6 rebounds and pulls the locking rod 5 back to the end before the slide groove 43. The protrusion 511 protrudes again, and the protrusions 511 of the two locking rods 5 are completely fitted. At this time, the protrusion 511 interacts with the plug-in column 41, so that the plug-in column 41 is locked in the plug-in hole 42 and cannot be pulled out. When the plug-in column 41 needs to be pulled out, it is only necessary to push the locking rod 5 to the other end of the slide groove 43, the protrusion 511 no longer protrudes, and the plug-in column 41 can be pulled out.

[0032] Reference Figures 3 to 5 In one embodiment of the present application, a receiving portion 411 is provided on the side wall surface of the plug-in column 41 facing the plug-in hole 42, and one end of the locking rod 5 has a hemispherical portion 51, which is fitted in the receiving portion 411. When the locking rod 5 is moved along the slide groove 43, the hemispherical portion 51 can partially protrude into the plug-in hole 42 to form a protrusion 511.

[0033] It can be understood that the accommodating portion 411 is a hemispherical groove, which is exactly consistent with the shape of the hemispherical portion 51 at the front end of the locking rod 5. When the locking rod 5 is at one end of the slide groove 43, the plane of the hemispherical portion 51 will be inclined, and one end of the hemispherical portion 51 will also protrude in the plug-in hole 42 to form a protrusion 511. When the locking rod 5 is at the other end of the slide groove 43, the inclined plane of the hemispherical portion 51 gradually flattens and is in the same horizontal plane with the side wall of the plug-in column 41.

[0034] When the two connecting members 3 approach each other, the front ends of the plug-in columns 41 of the two contact the inclined plane of the hemispherical portion 51 and compress the plane, the spring 6 is stretched, and the locking rod 5 slides to the other end of the slide groove 43. The plane of the hemispherical portion 51 is no longer inclined and is at the same horizontal plane as the side wall of the plug-in column 41. At this time, the plug-in column 41 can be fully inserted into the plug-in hole 42, and then the hemispherical portion 51 is no longer compressed, the spring 6 rebounds, and pulls the locking rod 5 back to the end before the slide groove 43. The plane of the hemispherical portion 51 is tilted again, and the planes of the two hemispherical portions 51 are completely fitted to form a sphere. At this time, the protrusion 511 interacts with the inner wall of the accommodating portion 411, so that the plug-in column 41 is locked in the plug-in hole 42 and cannot be pulled out. When the plug-in column 41 needs to be pulled out, the locking rod 5 only needs to be pushed to the other end of the slide groove 43, the protrusion 511 is no longer raised, and the plug-in column 41 can be pulled out.

[0035] Reference Figures 3 to 5 In one embodiment of the present application, an operating handle 52 is provided at the free end of the locking rod 5 , and the operating handle 52 passes through the side wall of the mounting platform 13 or the template 14 and partially protrudes outward.

[0036] It can be understood that the operating handle 52 is provided to facilitate the pushing of the locking rod 5 to one end of the slide groove 43 so that the protrusion 511 is no longer protruding, thereby facilitating the pulling out of the plug-in column 41 from the plug-in hole 42. Compared with the traditional welding and screw installation methods, this method undoubtedly makes the replacement process of the template 14 very convenient. The template 14 can be disassembled by simply pushing the locking rod 5, which can save a lot of time and manpower.

[0037] Reference Figures 2 to 3 In one embodiment of the present application, mounting grooves 15 are provided at the edges of the mounting platform 13 and the mating surfaces of the template 14 , and the connecting member is fixed in the mounting grooves 15 .

[0038] It can be understood that the setting of the installation groove 15 can facilitate the installation of the connector 3 therein, reduce a portion of the exposed volume of the connector 3, and only leave the plug-in column 41 for locking outside the installation groove 15. Through the above setting, when the template 14 and the mold base 1 are spliced ​​together, the connection between the two is tightly fitted without leaving any gap, and will not affect the stamping process of the shielding cover.

[0039] Reference Figures 2 to 3 In one embodiment of the present application, an operating channel 16 is provided on the side wall of the mounting groove 15 corresponding to the operating handle 52 .

[0040] It can be understood that the operating channel 16 is for the convenience of moving the operating handle 52. It should be noted that the length of the operating channel 16 should correspond to the length of the slide groove 43. When the operating handle 52 is moved to one end of the operating channel 16, the locking rod 5 should also be at the corresponding end of the slide groove 43, so as to facilitate the control of the locking rod 5.

[0041] The technical solution of the utility model is to set a connecting structure 2 at the connection between the template 14 and the mounting platform 13, each connecting structure 2 has two connecting parts 3, the connecting part 3 has a plug-in column 41 and a plug-in hole 42, and a locking rod 5 that penetrates the plug-in column 41, and a part of the locking rod 5 can be inserted into the plug-in hole 42. When the plug-in columns 41 of the connecting parts 3 on the template 14 and the mounting platform 13 are inserted into each other's plug-in holes 42 at the same time, the parts of the locking rods 5 of the two that extend into the plug-in holes 42 can cooperate with each other to lock, thereby completing the connection between the template 14 and the mounting platform 13. When disassembly is required, it is only necessary to move the locking rod 5 so that the part protruding into the plug-in hole 42 is no longer protruding, and the plug-in column 41 can be pulled out from the plug-in hole 42 to complete the disassembly. The technical solution can replace the template 14 more conveniently and quickly, save time and effort, and help improve production efficiency.
