Description

Technical Field

[0001] The utility model relates to the technical field of knife dies, in particular to an anti-falling knife die. Background Art

[0002] In different fields, the knife mold has different structures. For example, when it is necessary to punch products made of materials such as foam boards or plastic boards, the knife mold used has a relatively simple structure. Generally, the knife (matching the shape required for punching) is fixed on the template. For example, when it is necessary to punch out a circular foam board, the circular knife is fixed to the lower end of the template, and the desired product can be obtained by applying a downward force on the foam board.

[0003] Generally, the tool is fixed on the template. The tool can be inserted into the groove by cutting a groove on the template, or inserted into the groove by interference fit, or the positions of the two can be further fixed by coating glue, etc. However, the reliability is relatively weak. After multiple punching actions, the two are easy to loosen, which may cause the tool to fall. In addition, the two will have relative displacement, resulting in reduced punching accuracy.

[0004] In order to solve the above problems, the utility model patent with announcement number CN218985069U discloses an anti-drop-off knife die, including a template, a cutter and an insert. The upper part of the cutter is provided with a positioning hole that penetrates its body, and the template is provided with a slot that matches the cross section of the cutter. The upper part of the cutter is inserted into the slot, and the lower part of the cutter protrudes from the lower end surface of the template. The insert passes through the positioning hole and is positioned and abutted against the upper part of the template. The above-mentioned anti-drop-off knife die can prevent the cutter from moving relative to the template by inserting the cutter into the slot and fixing the cutter on the template by the insert, which can prevent the cutter from falling and moving when performing punching and cutting, thereby improving accuracy.

[0005] It can be seen from this that the existing cutting die has the problem of the cutting tool often falling off. Therefore, the utility model also provides an anti-falling cutting die. Utility Model Content
