Description

A reverse punching device for processing mobile phone protective cases Technical Field

[0001] This utility model relates to the technical field of mobile phone case processing, specifically a reverse punching mobile phone protective case processing device. Background Technology

[0002] The existing mobile phone case processing device, as shown in Figure 1, generally includes an upper mold 1, a lower mold 2, and a die-cutting tool 3 located at the lower part of the upper mold. The mobile phone case 4 is positioned between the upper mold 1 and the lower mold 2. The lower mold is designed to conform to the shape of the mobile phone case. The upper mold moves up and down relative to the lower mold, driving the die-cutting tool 3 to die-cut the mobile phone case and form the corresponding holes (such as camera holes) in the mobile phone case.

[0003] The problem with existing mobile phone case processing equipment is that, for some models of mobile phone cases, the distance between the die-cutting hole and the side of the case is too small. This results in the die-cutting wall of the contour structure set in the lower mold for the die-cutting hole being too narrow, which makes the manufacturing and processing of the lower mold extremely difficult and indirectly increases the manufacturing cost of the mold. Summary of the Invention

[0004] To address the technical problems and defects of existing technologies, this utility model provides a reverse punching mobile phone protective case processing device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a reverse punching mobile phone protective case processing device, including an upper mold, a lower mold and a die-cutting tool, the mobile phone protective case is placed between the upper mold and the lower mold, the die-cutting tool is used to die-cut the mobile phone protective case, the lower mold has a recessed structure, the outer side of the mobile phone protective case matches the inner side of the recessed structure, and the cutting edge of the die-cutting tool faces the inner side of the mobile phone protective case.

[0006] Preferably, the bottom of the recessed structure is provided with two or more vacuum suction holes, which are connected to a vacuum tube.

[0007] Preferably, the upper mold is connected to an automated control device, which controls its reciprocating up-and-down movement relative to the lower mold.

[0008] The beneficial effects of this utility model are:

[0009] This utility model provides a reverse punching processing device for mobile phone cases. The lower mold has a recessed structure, and the outer side of the mobile phone case matches the inner side of the recessed structure. The cutting edge of the die-cutting tool faces the inner side of the mobile phone case. This structure solves the technical problem that for some mobile phone case models, the distance between the die-cutting hole and the side of the case is too small, resulting in an excessively narrow die-cutting wall of the contour structure corresponding to the die-cutting hole, which greatly hinders the manufacturing and processing of the lower mold. This also reduces the cost of the mold. Attached Figure Description

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] This utility model discloses a reverse punching mobile phone protective case processing device. Its partial structural diagram is shown in Figure 2, and its partial exploded structural diagram is shown in Figure 3. It includes an upper mold 1, a lower mold 2, and a die-cutting tool 3. The mobile phone protective case 4 is placed between the upper mold 1 and the lower mold 2. The die-cutting tool 3 is used to die-cut the mobile phone protective case 4. The lower mold 2 has a recessed structure 21. The outer side of the mobile phone protective case 4 matches the inner side of the recessed structure 21. The cutting edge of the die-cutting tool 3 faces the inner side of the mobile phone protective case 4.

[0017] In a preferred embodiment, the bottom of the recessed structure 21 of this embodiment is provided with a plurality of arrayed vacuum suction holes 22. The vacuum suction holes 22 are connected to the vacuum tube 5. Through the suction force of the vacuum suction holes 22, the mobile phone protective case 4 can be adsorbed into the recessed structure 21. During the die-cutting process, the mobile phone protective case 4 is displaced, resulting in displacement of the die-cutting hole position or accuracy error of the mobile phone protective case 4.

[0018] In this embodiment, the upper mold 1 is connected to an automated control device, which controls its reciprocating up-and-down movement relative to the lower mold 2. It is understood that the upper mold 1 can also be manually controlled to reciprocate up-and-down.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a reverse punching processing device for mobile phone cases. The lower mold has a recessed structure, and the outer side of the mobile phone case matches the inner side of the recessed structure. The cutting edge of the die-cutting tool faces the inner side of the mobile phone case. This structure solves the technical problem that for some mobile phone case models, the distance between the die-cutting hole and the side of the case is too small, resulting in an excessively narrow die-cutting wall of the contour structure corresponding to the die-cutting hole, which greatly hinders the manufacturing and processing of the lower mold. This also reduces the cost of the mold.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
