The upper mold assembly 1 includes an upper template 11 and an upper fixing plate 12 screwed onto the lower surface of the upper template 11. A plurality of upper punching cutters 13 arranged in an array are clamped between the upper template 11 and the upper fixing plate 12, and the lower ends of each upper punching cutter 13 extend to the lower part of the upper fixing plate 12.

[0035] Among them, such as Figures 2 to 6 As shown, the lower mold assembly 2 of the fixture includes a lower mold base plate 21 and a lower mold panel 22. The lower mold panel 22 has a plurality of panel blanking holes 221 arranged in an array and vertically penetrating through each panel. The lower mold base plate 21 has a base plate blanking hole 211 that is vertically penetrating through and connected to the panel blanking holes 221.

[0036] Furthermore, such as Figures 2 to 6As shown, decorative ring positioning posts 222 protruding upwards are respectively provided on the upper surface of the lower die panel 22 at the upper opening edge of each panel blanking hole 221, and the lower die panel 22 is provided with a punching knife mounting hole 223 located next to the decorative ring positioning post 222 for each upper punching knife 13, and a lower punching knife 23 is respectively embedded in each punching knife mounting hole 223, and each lower punching knife 23 is provided with a sprue material positioning groove 231.

[0037] Furthermore, such as Figures 2 to 4 As shown, the upper mold assembly 1 of the fixture also includes an auxiliary pressure plate 14 located below the upper fixed plate 12. The auxiliary pressure plate 14 is connected to the upper fixed plate 12 through an elastic connecting assembly 15. The auxiliary pressure plate 14 is provided with vertical through pressure plate holes 141 corresponding to each upper punch cutter 13. The auxiliary pressure plate 14 is provided with a downward protruding decorative ring holding protrusion 142 at the lower opening edge of each pressure plate through hole 141.

[0038] It should be explained that, for the upper mold assembly 1 of this embodiment, it can be driven by a driving component to achieve lifting and lowering actions. This driving component can be a cylinder structure. The upper surface of the upper mold plate 11 is equipped with a driving component connector 5, which is connected to the outer end of the piston rod of the cylinder. The mobile phone camera decorative ring punching fixture of this embodiment can be installed on a bracket structure. The aforementioned driving component is installed at the upper end of the bracket structure, and the lower mold base plate 21 is securely installed at the lower end of the bracket.

[0039] In the operation of the mobile phone camera decorative ring punching fixture in this embodiment, the operator first places the injection-molded mobile phone camera decorative ring semi-finished product 6 onto several decorative ring positioning posts 222 on the lower mold panel 22. The decorative ring plastic part 61 of the mobile phone camera decorative ring semi-finished product 6 is fitted and positioned on the decorative ring positioning posts 222 to achieve positioning of the decorative ring plastic part 61. During the process of placing the mobile phone camera decorative ring semi-finished product 6 onto the decorative ring positioning posts 222, the sprue part 62 of the mobile phone camera decorative ring semi-finished product 6 is aligned and placed into the sprue positioning groove 231 of the lower punching cutter 23. Through the cooperation of the decorative ring positioning posts 222 and the sprue positioning groove 231, the mobile phone camera decorative ring semi-finished product 6 is accurately positioned. After the mobile phone camera decorative ring semi-finished product 6 is positioned and placed, the upper mold of the fixture... Component 1 moves downward under the driving action of the driving component. During this process, the auxiliary pressure plate 14 first contacts the semi-finished mobile phone camera decorative ring 6, and the decorative ring holding protrusion 142 of the auxiliary pressure plate 14 presses down on the decorative ring plastic part 61 of the semi-finished mobile phone camera decorative ring 6 to achieve the fixing of the decorative ring plastic part 61 before the sprue is punched. As the driving component drives the upper mold assembly 1 of the fixture to continue to move downward, the upper punch cutter 13 and the lower punch cutter 23 cooperate to cut the sprue material, so as to achieve the punching separation of the decorative ring plastic part 61 and the sprue material part 62. The sprue material part 62 after punching separation falls down through the panel drop hole 221 and the bottom plate drop hole 211. After the sprue punching is completed, the driving component drives the upper mold assembly 1 of the fixture to move upward and reset. The operator can then remove the finished decorative ring plastic part with the sprue material punched off from the decorative ring positioning post 222.

[0040] It should be emphasized that in the process of using the sprue punching fixture of the mobile phone camera decorative ring in this embodiment to perform the sprue punching operation, this embodiment uses the decorative ring positioning post 222 and the sprue material positioning groove 231 to accurately position the semi-finished mobile phone camera decorative ring 6. Before the upper punching blade 13 and the lower punching blade 23 cooperate to cut off the sprue material part 62, the auxiliary pressure plate 14 uses the decorative ring holding protrusion 142 to press the decorative ring rubber part 61 of the semi-finished mobile phone camera decorative ring 6. This can prevent the decorative ring rubber part 61 from swinging and shifting during the punching action, thus affecting the punching quality and effectively ensuring the quality of sprue punching.

[0041] In addition, the punching fixture for the mobile phone camera decorative ring in this embodiment can realize the punching and cutting of multiple semi-finished mobile phone camera decorative rings with 6 sprues, which has high work efficiency.

[0042] In summary, the above structural design allows the mobile phone camera decorative ring punching fixture of this embodiment to be effectively applied to the punching of the sprue of the mobile phone camera decorative ring, and it has the advantages of novel structural design and high efficiency in punching the sprue of the mobile phone camera decorative ring.
