[0043] A die for trademark die-cutting, as Figures 1 to 3 shown, includes an upper template 10, a lower template 20 disposed below the upper template 10, and a cutting tool 30 assembled on the upper template 10. The upper and lower templates are assembled on a punching machine 40. The cutting tool 30 is embedded in the upper template 10 and is in interference fit with the upper template 10.

[0044] The punching machine 40 includes a loading platform 41, a gantry 42 is fixedly installed on the top of the loading platform 41, and a hydraulic cylinder 43 is fixedly installed in the middle of the gantry 42. The hydraulic cylinder 43 is arranged vertically downward, and a connecting plate 44 is fixed to the driving end of the hydraulic cylinder 43. In this embodiment, the upper template 10 is installed at the bottom of the connecting plate 44 in an adhesive manner. As Figures 2 to 3 shown, a positioning pin 45 for positioning the upper template 10 is provided on the connecting plate 44, and a positioning hole 11 corresponding to the position of the positioning pin 45 is opened on the top surface of the upper template 10. The positioning pin 45 is inserted into the positioning hole 11 to position the relative position of the upper template 10 and prevent the upper template 10 from moving relatively during use. The lower template 20 is fixed to the top of the loading platform 41. Among them, the number of the positioning pins 45 is greater than or equal to two. In this embodiment, the number of the positioning pins 45 is two, which realizes the effective positioning of the upper template 10.

[0045] As Figure 4 shown, a plurality of elastic limit blocks 13 are provided on the bottom surface of the upper template 10. The plurality of elastic limit blocks 13 are distributed around the cutting tool 30. When the elastic limit blocks 13 are in a free state, the bottom surface of the elastic limit blocks 13 is lower than the bottom surface of the cutting tool 30. The elastic limit blocks 13 can not only press and fix the silicone trademark placed on the lower template 20 to prevent the silicone trademark from shifting when the cutting tool 30 performs die-cutting on the silicone trademark, but also effectively limit the descending height of the cutting tool 30 to avoid excessive collision between the cutting tool 30 and the lower template 20, and effectively protect the cutting tool 30. In this embodiment, the elastic limit blocks 13 are made of rubber.

[0046] Furthermore, the upper template 10 is made of a wooden board or a plastic board, which can not only effectively reduce the weight and manufacturing cost of the upper template 10, but also provide a certain buffer for the cutting tool 30, effectively protecting the cutting tool 30 and increasing its service life. In this embodiment, the thickness of the upper template 10 is 15 mm to 30 mm.

[0047] Furthermore, the lower template 20 is made of a wear-resistant plastic board, thereby effectively protecting the cutting edge of the cutting tool 30 and extending its service life.

[0048] As Figure 5 and Figure 6 shown, the cutting edge of the cutting tool 30 is a circular cutting edge with a rounded corner. The cutting tool 30 is formed by bending and enclosing a blade 31. The cutting edge of the blade 31 faces downward and extends below the upper template 10. In this embodiment, the distance from the cutting edge of the blade 31 to the bottom surface of the upper template 10 is 25 mm to 30 mm. The back of the blade 31 is embedded in the upper template 10. In order to release stress and reduce the installation difficulty, a plurality of buffer notches 311 are spaced apart along the edge of the back of the blade 31. The buffer notches 311 extend downward until the end of the buffer notches 311 is located below the upper template 10, so that the blade 31 can better release stress and extend the service life of the blade 31. The plurality of buffer notches 311 divide the back of the blade 31 into a plurality of connecting portions 312, and corresponding installation grooves 12 are formed on the upper template 10 to match the corresponding connecting portions 312. Among them, the number of the connecting portions 312 is the same as that of the installation grooves 12, and the positions correspond to each other one by one.

[0049] In this embodiment, four buffer notches 311 are formed on the back of the blade 31, thereby dividing the back of the blade 31 into four connecting portions 312. Four installation grooves 12 are correspondingly formed on the upper template 10, and the four installation grooves 12 are spaced apart.

[0050] Furthermore, a plurality of elastic unloading blocks 14 are provided on the bottom surface of the upper template 10. When the elastic unloading blocks 14 are in a free state, the bottom surface of the elastic unloading blocks 14 is lower than the bottom surface of the cutting tool 30. The plurality of elastic unloading blocks 14 are distributed in the inner circle of the cutting tool 30 and are used to assist the separation of the silicone trademark after die-cutting from the cutting edge, thereby enabling the silicone trademark to be smoothly demolded. In this embodiment, the elastic unloading blocks 14 are made of rubber.

[0051] In this embodiment, the working principle of the mold is as follows:

[0052] Place the silicone trademark to be die-cut on the lower template 20, and the hydraulic cylinder 43 drives the upper template 10 to move downward. During the downward movement of the upper template 10, the elastic limit block 13 and the elastic unloading block 14 first contact the silicone trademark, and then the cutting edge of the cutting tool 30 contacts the silicone trademark and performs die-cutting on the silicone trademark. After die-cutting is completed, the hydraulic cylinder 43 drives the upper template 10 to move upward, and the elastic unloading block 14 rebounds and unfolds, that is, the bottom surface of the elastic unloading block 14 pushes the silicone trademark downward to assist in demolding the silicone trademark.

[0053] In this embodiment, by using a wooden board or a plastic board to make the upper template, the weight and manufacturing cost of the upper template can be effectively reduced, and a certain buffer can be provided for the cutting tool, effectively protecting the tool and increasing its service life; by setting a buffer notch on the back of the blade, the installation difficulty of the cutting tool is reduced, the stress generated during die-cutting of the cutting tool is effectively released, the tool is effectively protected, and its service life is increased. Embodiment

[0054] The structure of this embodiment is basically the same as that of Embodiment 1.

[0055] The difference is that, as Figure 7 shown, for a mold with a larger specification, the upper template 10 is provided with a weight-reducing hole 15 for effectively reducing the weight of the upper template 10. In this embodiment, the weight-reducing hole 15 is opened at the center of the upper template 10. Two elastic unloading blocks 14 are provided on the bottom surface of the upper template 10, and the two elastic unloading blocks 14 are distributed on both sides of the weight-reducing hole 15.

[0056] In this embodiment, by providing a weight-reducing hole, the weight of the upper template is effectively reduced to reduce the difficulty of handling and replacing the upper template. Embodiment

[0057] The structure of this embodiment is basically the same as that of Embodiment 1.

[0058] As Figures 8 to 10 shown, the difference is that in this embodiment, the cutting edge of the cutting tool 30 is a rectangular cutting edge. The cutting tool 30 is formed by splicing and enclosing four blades 31. The cutting edge of the blade 31 faces downward and extends below the upper template 10. The backs of the four blades 31 are respectively embedded in the upper template 10. A buffer notch 311 is provided at the back edge of each blade 31. The buffer notch 311 extends downward until the end of the buffer notch 311 is located below the upper template 10, so that the blade 31 can better release stress and extend the service life of the blade 31. The buffer notch 311 divides the back of the corresponding blade 31 into a plurality of connecting parts 312, and corresponding installation grooves 12 are provided on the upper template 10 to be adapted to the corresponding connecting parts 312.

[0059] In this embodiment, a buffer notch 311 is formed on the back of each blade 31, thereby dividing the back of the blade 31 into two connecting parts 312. Four mounting grooves 12 are correspondingly formed on the upper template 10, and the four mounting grooves 12 are arranged at intervals. The two mutually spliced connecting parts 312 are embedded in the same mounting groove 12.

[0060] Furthermore, since the cutting edge of the cutting tool 30 in this embodiment is a rectangular cutting edge, the four corners of the silicone trademark after die cutting are all right angles. The demolding difficulty of a right-angle structure is much greater than that of a rounded-corner structure. Therefore, in order to ensure the smooth demolding of the silicone trademark, an air flow channel 16 is formed on the upper template 10. In this embodiment, the air flow channel 16 is provided with an air inlet 161 and a plurality of air outlets 162. The air inlet 161 is horizontally formed on the side wall of the upper template 10. The air outlets 162 are vertically formed on the bottom surface of the upper template 10 and are distributed inside the inner circle of the cutting tool 30. In this embodiment, as Figures 8 to 10 shown, the air flow channel 16 is provided with one air inlet 161 and four air outlets 162. The four air outlets 162 are arranged near the four corners of the inner circle of the cutting tool 30.

[0061] In this embodiment, as Figure 12 and Figure 13 shown, the air inlet 161 is formed on the rear side wall of the upper template 10. The air flow channel 16 has a main flow channel 163. The main flow channel 163 is horizontally arranged, distributed between two adjacent mounting grooves 12, and is arranged at intervals with the mounting grooves 12. The main flow channel 163 extends forward from the air inlet 161 to the center of the inner circle of the cutting tool 30. Two main branch flow channels 164 are formed at the front end of the main flow channel 163. The two main branch flow channels 164 are horizontally arranged and extend left and right respectively, extending to near the inner wall of the cutting tool 30. Two secondary flow channels 165 are formed at the end of the main branch flow channel 164 far from the main flow channel 163, and the main branch flow channel 164 is communicated with the corresponding secondary flow channel 165. The secondary flow channel 165 is horizontally arranged, and the end of the secondary flow channel 165 far from the main branch flow channel 164 is communicated with the upper end of the air outlet 162.

[0062] Furthermore, the staff can form the air flow channel 16 on the upper template 10 by punching. After punching, the required sealing holes on the upper template 10 are sealed by plugs 166 to ensure the airtightness of the whole air flow channel 16.

[0063] In this embodiment, the working principle of the air flow channel 16 is as follows:

[0064] As Figure 13As shown, after the cutting tool 30 finishes die cutting, the operator injects compressed air into the air inlet 161 through an air pipe, and the compressed air is discharged into the main flow channel 163 through the air inlet 161; the compressed air in the main flow channel 163 is divided into four sub-flow channels 165 through two main branch flow channels 164; the compressed air in the sub-flow channel 165 is blown downward through the air outlet 162, that is, the air flow channel 16 blows air downward at the four top corners of the silicone trademark, so that the silicone trademark is separated from the cutting tool 30, and thus the silicone trademark is smoothly demolded.

[0065] In this embodiment, an air flow channel is provided to assist the smooth demolding of the silicone trademark.

[0066] The other components and operations of a trademark die-cutting mold according to an embodiment of the present invention are known to those of ordinary skill in the art, and will not be described in detail here.
