Description

A die-cutting device for mobile phone protective cases Technical Field

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

[0002] Existing mobile phone case processing equipment generally includes an upper mold, a lower mold, and a die cutter located at the lower part of the upper mold. A die-cutting base for placing the mobile phone case is fixedly installed on the upper part of the lower mold. The upper mold moves up and down relative to the lower mold, driving the die cutter to die-cut the semi-finished mobile phone case to form the corresponding mobile phone case holes (such as camera holes).

[0003] The existing mobile phone case processing equipment has the following problems: when the upper mold and die cutter are controlled to move downwards to complete the die-cutting operation by manual or automatic control, the upper mold and die cutter may make hard contact due to insufficient accuracy of the upper and lower mold movement strokes or deviations generated during long-term production, which may damage the die cutter. There is also the possibility that the upper mold and die cutter are not fully pressed together, resulting in incomplete die-cutting. Summary of the Invention

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

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mobile phone protective case processing device for lower die punching, including an upper die, a lower die, and a die-cutting tool. The mobile phone protective case is placed between the upper die and the lower die. The die-cutting tool is used to die-cut the mobile phone protective case. The die-cutting tool is fixedly mounted on the lower die, and the cutting edge of the die-cutting tool faces the upper die. A flexible pressure plate is provided at the bottom of the upper die. The upper die can move relative to the lower die to drive the flexible pressure plate to press against the cutting edge of the die-cutting tool to complete the die-cutting.

[0006] Preferably, the outer contour of the lower mold is matched with the inner contour of the mobile phone case to position the mobile phone case.

[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] The present invention provides a mobile phone protective case processing device for lower die punching. The die-cutting tool is fixedly mounted on the lower die, with the cutting edge of the die-cutting tool facing the upper die. A flexible pressure plate is provided at the bottom of the upper die. The upper die can move relative to the lower die to drive the flexible pressure plate to press against the cutting edge of the die-cutting tool to complete the die cutting. By pressing the cutting edge of the die-cutting tool against the flexible pressure plate, the operating stroke is more controllable. This avoids the situation in the prior art where insufficient precision of the upper and lower die movement strokes or deviations during long-term production can lead to hard contact between the upper die and the die-cutting tool, thereby damaging the die-cutting tool, or the upper die and the die-cutting tool not being fully pressed against each other, resulting in incomplete die cutting.

[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 mobile phone protective case processing device for lower die punching. Its overall structural diagram is shown in Figure 1, its exploded structural diagram in Figure 2, and its cross-sectional structural diagram in Figure 3. It includes an upper die 1, a lower die 2, a die-cutting tool 3, and a flexible pressure plate 5. The mobile phone protective case 4 is placed between the upper die 1 and the lower die 2. The outer contour of the lower die 2 matches the inner contour of the mobile phone protective case 4 to position the mobile phone protective case 4. The die-cutting tool 3 is used to die-cut the mobile phone protective case 4. The die-cutting tool 3 is fixedly mounted on the lower die 2, with its cutting edge facing the upper die 1. A flexible pressure plate 5 is provided at the bottom of the upper die 1. The upper die 1 can move relative to the lower die 2, causing the flexible pressure plate 5 to press against the cutting edge of the die-cutting tool 3 to complete the die-cutting.

[0017] 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.

[0018] The beneficial effects of this utility model are:

[0019] The present invention provides a mobile phone protective case processing device for lower die punching. The die-cutting tool is fixedly mounted on the lower die, with the cutting edge of the die-cutting tool facing the upper die. A flexible pressure plate is provided at the bottom of the upper die. The upper die can move relative to the lower die to drive the flexible pressure plate to press against the cutting edge of the die-cutting tool to complete the die cutting. By pressing the cutting edge of the die-cutting tool against the flexible pressure plate, the operating stroke is more controllable. This avoids the situation in the prior art where insufficient precision of the upper and lower die movement strokes or deviations during long-term production can lead to hard contact between the upper die and the die-cutting tool, thereby damaging the die-cutting tool, or the upper die and the die-cutting tool not being fully pressed against each other, resulting in incomplete die cutting.
