Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold equipment, and specifically relates to a protective film punching die structure that is easy to fix. Background Technology
[0002] Protective film punching dies are tools used for punching protective films. Currently, some protective film punching dies have areas for improvement in their fixing structure. In actual operation, displacement and wobbling are prone to occur during the punching process. This is mainly because the high-frequency vibration and large punching force generated by the punch press exert continuous external forces on the die, and without a stable fixing method, the die cannot maintain its stability.
[0003] The conventional approach is to use simple bolts to directly connect the mold to the work platform. While this method can limit mold movement to some extent, it has several drawbacks. First, the limited number and locations of bolts make it difficult to fully balance the cutting force. In areas with high cutting force, the mold may still experience slight displacement, which, over time, leads to accelerated mold wear and reduces its lifespan. Second, repeated tightening and loosening of bolts can easily cause stripping of the threads, reducing the reliability of the fixation. Once stripping occurs, the threads need to be re-machined or related mold components replaced, increasing maintenance costs and downtime. Therefore, a new structure is needed to solve these technical problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective film punching die structure that is easy to fix, thereby solving the problems mentioned in the background art.

[0006] In a preferred embodiment, the lower mold assembly includes a base plate, a base, and a mold seat. The base is mounted on the upper surface of the base plate, and the mold seat is mounted on the upper surface of the base. The length and width of the mold seat match the length and width of the base.

The fixing component 1 includes a fixing rod and a threaded rod. The lower surface of the fixing rod is integrally formed with a threaded rod through a limiting plate. The diameter of the threaded rod matches the inner diameter of the threaded hole. In use, the fixing component 1 can play a role in initial positioning and guidance, and can quickly place the lower mold body into the approximate installation position of the mold base, making subsequent precise fixing more convenient.
[0008] In a preferred embodiment, the fixing rod is fixed inside the threaded hole by a threaded rod and a limiting plate, and multiple fixing parts are installed on the upper surface of the mold base through multiple threaded holes. A buffer post is installed at each of the four corners of the upper surface of the mold base.

The end of the buffer pillar away from the mold seat is connected to the lower surface of the mold cover, and an electric push rod is installed on the upper surface of the mold cover for moving the upper mold body.
[0010] In a preferred embodiment, the upper mold body is movably mounted on the lower surface of the mold cover via an electric push rod and a buffer column. The upper mold body and the lower mold body are matched with each other. The lower mold body is fixed to the upper surface of the mold base by a plurality of fasteners.
[0011] In a preferred embodiment, the left and right surfaces of the lower mold body are recessed inward to form fixing grooves, and the lower surface of the lower mold body is uniformly provided with a plurality of fixing holes, the number and position of which match the number and position of the fixing component.

The first fixing plate is installed on the left and right edges of the upper surface of the mold base, and the second fixing plate is installed on the inner surface of the first fixing plate via two cylinders.
[0013] The structure of the second fixing plate matches the structure of the fixing groove. The second fixing plate is set inside the fixing groove by a cylinder. In use, by controlling the extension and retraction of the cylinder, the second fixing plate can be moved closer to and further away from the first fixing plate, thereby quickly completing the clamping and loosening operation of the lower mold body.
[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a fixing component one, the fixing component includes a fixing component one and a fixing component two for fixing the lower mold body. The fixing component one includes a fixing rod and a threaded rod. The lower surface of the fixing rod is integrally formed with a threaded rod through a limiting plate. When in use, the fixing component one can play a role in initial positioning and guidance, and can quickly place the lower mold body into the approximate installation position of the mold base, making subsequent precise fixing more convenient, ensuring the positional accuracy of the lower mold body each time it is installed, ensuring the consistency of mold installation, and thus improving the accuracy and stability of punching.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a protective film punching die structure that is easy to fix, including: a die assembly and a fixing assembly. The die assembly has a fixing assembly installed inside for fixing the lower die part. The die assembly includes an upper die part and a lower die part for producing a protective film punching die. The fixing assembly includes a fixing member 300 and a fixing member 2 for fixing the lower die body 140. There are multiple sets of fixing members 300 and two sets of fixing members 2.
[0028] Please see Figures 1 to 5 As the first embodiment of this utility model: the lower mold assembly includes a base plate 100, a base 110 and a mold seat 120. The base 110 is installed on the upper surface of the base plate 100, and the mold seat 120 is installed on the upper surface of the base 110. The length and width of the mold seat 120 match the length and width of the base 110.
[0029] The upper surface of the mold base 120 is provided with a plurality of threaded holes 121 evenly distributed at the center position. The fixing component 300 includes a fixing rod 310 and a threaded rod 320. The lower surface of the fixing rod 310 is integrally formed with the threaded rod 320 through a limiting plate. The diameter of the threaded rod 320 matches the inner diameter of the threaded hole 121.
[0030] The fixing rod 310 is fixed inside the threaded hole 121 by the threaded rod 320 and the limiting plate. Multiple fasteners 300 are installed on the upper surface of the mold base 120 through multiple threaded holes 121. A buffer post 130 is installed at each of the four corners of the upper surface of the mold base 120.
[0031] The upper mold component includes a mold cover 200 and an upper mold body 210. The end of the buffer pillar 130 away from the mold base 120 is connected to the lower surface of the mold cover 200. An electric push rod 220 is installed on the upper surface of the mold cover 200 for moving the upper mold body 210.
[0032] The upper mold body 210 is movably mounted on the lower surface of the mold cover 200 via an electric push rod 220 and a buffer column 130. The upper mold body 210 and the lower mold body 140 are matched with each other. The lower mold body 140 is fixed on the upper surface of the mold base 120 by multiple fasteners 300.
[0033] In use, the user first threads multiple fasteners 300 onto the upper surface of the mold base 120 via their internal threaded rods 320, ensuring that the fixing rods 310 inside the fasteners 300 are positioned on the upper surface of the mold base 120. After securing the multiple fasteners 300, the user can remove the lower mold body 140, which is initially fixed to the upper surface of the mold base 120 by the fasteners 300. After the lower mold body 140 is initially secured, the user can then perform a secondary fixation using the second fastener, thus finally completing the fixation of the lower mold body 140. After the lower mold body 140 is fixed, the user can then activate the electric push rod 220 connected to the upper mold body 210 to perform subsequent operations (the specific mold operation process and mold structure are not detailed here; users can choose according to their actual situation). Since the fixing part 300 can play a preliminary positioning and guiding role, it can quickly place the lower mold body 140 into the approximate installation position of the mold base 120, making subsequent precise fixing more convenient, ensuring the positional accuracy of the lower mold body 140 each time it is installed, ensuring the consistency of mold installation, and thus improving the accuracy and stability of punching.
[0034] Please see Figures 1 to 5 As a second embodiment of the present utility model: the left and right surfaces of the lower mold body 140 are recessed inward to form a fixing groove 141, and the lower surface of the lower mold body 140 is evenly provided with a plurality of fixing holes, the number and position of the fixing holes matching the number and position of the fixing member 300.
[0035] The second fixing component includes a first fixing plate 400, a second fixing plate 410, and a cylinder 420. The first fixing plate 400 is installed on the left and right edges of the upper surface of the mold base 120, and the second fixing plate 410 is installed on the inner surface of the first fixing plate 400 through two cylinders 420.
[0036] The structure of the second fixing plate 410 matches the structure of the fixing groove 141, and the second fixing plate 410 is set inside the fixing groove 141 by the cylinder 420.
[0037] In use, after the lower mold body 140 is fixed through the operation steps of the first embodiment, the user can then activate the cylinder 420 on the outer surface of the fixing plate 400 to extend the telescopic rod of the cylinder 420, thereby moving the fixing plate 410 on the inner surface of the fixing plate 400. After the fixing plate 410 is moved into the fixing groove 141 of the lower mold body 140 by the cylinder 420, the cylinder 420 stops working, thus completing the secondary fixation of the lower mold body 140 through the fixing parts 2 on both sides. When it is necessary to remove the mold body 140 for replacement, the user only needs to reverse the above steps. By controlling the extension and retraction of the cylinder 420, the fixing plate 410 can be quickly moved closer to and away from the fixing plate 400, thereby quickly completing the clamping and loosening operation of the lower mold body 140. When combined with the fixing part 300, compared with the traditional mechanical clamping method, it greatly saves operation time and improves production efficiency, especially suitable for frequent clamping operations in batch production.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
