Its background technology proposes that "the existing engraving die cannot automatically clean the waste generated when the engraving die is working, and the staff needs to clean it manually, which is not only inefficient but also a waste of time. At the same time, the existing engraving die lacks a structure for pre-fixing the film material placed on the lower die body when in use. When it is cutting the film, it is easy to move, causing imprinting when cutting the film or deviation or defect in the product size." Therefore, the technical solution to this problem is "including an upper die body, a lower die body is provided at the bottom of the upper die body, a cutting film is installed at the bottom of the upper die body, and a cutting groove for use with the cutting film is opened on the top of the lower die body.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: although the waste cleaning effect is achieved through the provided technical solution, it is not convenient to automatically discharge and clean the waste after die cutting during use. The above solution still requires personnel to regularly take out the waste cleaning box to clean the waste. If the personnel cannot take it out and clean it in time, it is easy to cause waste accumulation and affect the processing, thereby reducing the convenience of use, cleaning effect and efficiency. Utility Model Content

[0021] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0022] Example 1

[0023] Reference Figure 1-4 As shown, an automatic waste-clearing engraving die comprises: a base 1 and a lower die body 2 fixedly mounted on the top thereof, a waste-clearing groove is provided on the top of the lower die body 2, a discharge groove connected to the waste-clearing groove is provided on one side of the lower die body 2, a plurality of fixed rods 3 fixedly mounted on the inner wall of the waste-clearing groove, a fixed block 4 fixedly connected to the ends of the plurality of fixed rods 3, an upper die body 5 arranged above the lower die body 2, the upper die body 5 is moved along the height direction of the base 1 by a lifting mechanism arranged on the base 1, a cutting die 6 fixedly mounted on the bottom of the upper die body 5, the cutting die 6 is provided with an avoidance groove for use with the fixed rod 3, a push plate 7 is slidably connected to the other side of the lower die body 2 and located in the waste-clearing groove, the cross section of the push plate 7 is L-shaped, and a linear transmission mechanism is provided on the lower die body 2 and connected to the push plate 7, the push plate 7 can move in the waste-clearing groove through the linear transmission mechanism when the upper die body 5 is raised or lowered.

[0024] The linear transmission mechanism includes an L-shaped bracket 8 fixedly mounted on one side of the base 1, a screw 9 rotatably connected between the vertical section of the bracket 8 and one side of the base 1, a connecting block 10 fixedly mounted at a corner of the top of the push plate 7 and threadedly connected to the screw 9, a gear 11 fixedly mounted on the surface of the screw 9, and a rack 12 fixedly mounted on the bottom of the upper mold body 5 and meshing with the gear 11.

[0025] The present embodiment provides a technical solution. When in use, the upper mold body 5 is driven downward by the lifting mechanism to contact the lower mold body 2, and the die cutting knife 6 is used to cut the material. The cut waste falls into the waste cleaning trough for temporary storage. During the downward movement of the upper mold body 5, the rack 12 can be synchronously driven downward, so that the rack 12 drives the gear 11 engaged with it to rotate, thereby driving the screw rod 9 to rotate, and cooperating with the connecting block 10 to drive the push plate 7 to move away from the discharge trough. When the upper mold body 5 contacts the lower mold body 2, the vertical section of the push plate 7 is just moved to the inner end of the waste cleaning trough, so that The waste that has been cut falls into the waste cleaning trough. When the upper mold body 5 moves upward, the rack 12 cooperates with the gear 11 to drive the screw 9 to reverse, so that the push plate 7 moves toward the discharge trough and pushes the waste that has fallen into the waste cleaning trough to be discharged through the discharge trough. Therefore, the waste that has fallen into the waste cleaning trough is automatically cleaned and discharged after each die cutting. During the process, there is no need for manual regular cleaning by personnel, which avoids the situation where personnel cannot clean in time and cause waste accumulation to affect die cutting, reduces long-term labor and dependence on manual labor, and effectively improves the convenience of use and cleaning effect and efficiency.

[0026] Preferably: the lifting mechanism includes a support rod 13 fixedly installed at the four corners of the top of the base 1, a mounting plate 14 fixedly connected to the top of the support rod 13 and a hydraulic cylinder 15 fixedly installed on the top of the mounting plate 14, the output end of the hydraulic cylinder 15 movably passes through the mounting plate 14 and is connected to the upper mold body 5, and the upper mold body 5 and the support rod 13 are slidably connected, wherein the hydraulic cylinder 15 can be replaced by an electric push rod or an electric cylinder, which is not the only limitation here.

[0027] Specifically, when cutting the material, the material to be cut is placed on the lower mold body 2 so that the material contacts the fixed block 4. The hydraulic cylinder 15 can drive the upper mold body 5 to move downward, so that the upper mold body 5 moves downward along the surface of the support rod 13 and contacts and cooperates with the lower mold body 2, and the die cutting knife 6 contacts the material to perform die cutting. The waste generated by die cutting falls into the waste cleaning groove in the lower mold body 2. After die cutting, the hydraulic cylinder 15 drives the upper mold body 5 to move up and reset again. Repeating the above steps can achieve the effect of die cutting the material.

[0028] Example 2

[0029] Based on the first embodiment, in this embodiment: a sliding cavity 16 is provided at the bottom of the upper mold body 5 , and a pressing mechanism for fixing the material to be cut is provided in the sliding cavity 16 .

[0030] The pressing mechanism includes a telescopic rod 17 fixedly mounted on the top wall of the sliding cavity 16, a limit pressure block 18 fixedly connected to the bottom end of the telescopic rod 17, and a spring 19 sleeved on the surface of the telescopic rod 17. The ends of the spring 19 are respectively connected to the limit pressure block 18 and the inner top wall of the sliding cavity 16. The inner wall of the sliding cavity 16 is provided with a plurality of limit grooves, and the limit pressure block 18 is mounted with a limit block that slides with the limit grooves to ensure the stability of the movement of the limit pressure block 18. The telescopic rod 17 is composed of a sleeve and a sleeve rod slidably connected to the sleeve.

[0031] This embodiment provides a technical solution that, when the upper mold body 5 moves downward to die-cut the material, can drive the limiting pressure block 18 to move downward synchronously, so that the limiting pressure block 18 contacts the material first, so as to fix the material and prevent the film material from shifting. At the same time, as the upper mold body 5 moves downward, the limiting pressure block 18 is forced to move into the sliding cavity 16 and squeeze the telescopic rod 17 and the spring 19. When the upper mold body 5 moves upward and resets, the spring 19 drives the limiting pressure block 18 to move downward and reset, thereby effectively ensuring the accuracy of the die cutting and the processing effect of the material.

[0032] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
