Description

Technical Field

[0001] The invention belongs to the technical field of die cutting and relates to a tool for preventing product embossing. Background Art

[0002] Die cutting, also known as die cutting mold processing, is a processing method that forms customized parts of different sizes by processing and cutting materials according to predetermined shapes. Specifically, the raw materials that pass through the die cutting station can be die-cut by a die cutting machine to obtain corresponding parts. Therefore, die cutting can be understood as cutting, and the material is cut into the required shape by the die cutting station.

[0003] like Figure 1 and Figure 2 The die-cut product shown in the figure is in the shape of a rectangular parallelepiped as a whole, and includes a release film 1 for carrying a product, a first double-sided adhesive layer 2, a first PI film layer 3, a second double-sided adhesive layer 4, and a second PI film layer 5 which are stacked in sequence. Figure 3 The die-cutting tool shown in the figure is used for processing. The die-cutting process is as follows Figure 4 As shown, the die-cut product is obtained by laminating, punching and waste removal. Before the die-cut product is assembled by the downstream customer, it is generally tested by a machine to see if its size meets the requirements. However, during the die-cutting process, due to the pressure of the die-cutting tool, the product is prone to embossing and causing deviation in product size. This phenomenon is particularly obvious at the corners of the product. Summary of the invention

[0004] The purpose of the present invention is to provide a tool for preventing product embossing, which is used to solve the problem that product embossing is easily generated during the die-cutting process, thereby affecting the accuracy of subsequent product size verification and detection.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A cutting tool for preventing product embossing comprises a cutting plate and a cutting line arranged on the cutting plate, wherein the cutting line comprises an angular fold line segment with an included angle not exceeding 135°, and is characterized in that a rebound layer extending into the included angle of the angular fold line segment is also provided on the cutting plate, and an angular groove matching the angular fold line segment is also provided within the included angle of the angular fold line segment.

[0007] Furthermore, the resilience layer is made of hard silicone foam.

[0008] Furthermore, the Shore hardness of the hard silicone foam is not less than 60HD.

[0009] Furthermore, the included angle of the angular broken line segment is 90°.

[0010] Furthermore, the knife line is a rectangular knife line.

[0011] Furthermore, the resilience layer is laid inside the rectangular knife line.

[0012] Furthermore, the angular slots are arranged at the four corners of the rectangular knife line.

[0013] Furthermore, the angular slots are L-shaped slots adapted to the four corners of the rectangular knife line.

[0014] Furthermore, the angular slot is a through slot that penetrates the blade.

[0015] Furthermore, the angled slots include straight slots respectively parallel to two sides of the angled fold line segment.

[0016] Compared with the prior art, the present invention has the following characteristics:

[0017] 1) The present invention eliminates embossing by filling a resilient layer, preferably a hard silicone foam layer, inside the tool cavity;

[0018] 2) In order to solve the problem of prominent embossing effect on the corners of tool engravings, the present invention provides slots at corresponding positions of the corners to reduce local foam pressure and foam rebound force loss, thereby achieving the purpose of preventing product embossing.
