Abstract
Description
Technical Field
[0001] This utility model relates to the field of molding die technology, and in particular to a dense mesh punching die. Background Technology
[0002] For products with densely packed mesh holes, conventional one-time stamping is difficult due to the numerous holes, easily resulting in deformation and failing to meet processing requirements. Existing dense mesh stamping mechanisms use a tower-type rotary high-speed single-punch method, requiring multiple rotations for stamping, which is cumbersome, has an excessively long production cycle time, and is extremely inconvenient to operate. Moreover, multiple rotations result in poor product consistency, affecting the overall product performance. Utility Model Content

The length of each punch is different. A lower fixed plate is provided on the lower die base, and a die plate is provided on the lower fixed plate. The die plate has die holes corresponding to each punch. A pressure plate is provided between the upper fixed plate and the die plate. The pressure plate is used to press the product to be punched on the die plate when the die is closed and to help the product be unloaded when the die is opened.
[0006] As an alternative, adjacent punches have different lengths.
[0007] As an alternative, the length of the punch decreases sequentially from the center to the edge of the product.

[0012] As an alternative, the upper mold base is provided with an outer guide post, and the lower mold base is provided with an outer guide sleeve that mates with the outer guide post.
[0013] As an alternative, limit posts are provided on both the upper and lower mold bases, and the limit posts of the upper mold base abut against the limit posts of the lower mold base when the mold is closed.
[0014] As an alternative, a lower support plate is provided below the lower mold base, and a pad is provided between the lower support plate and the lower mold base.
[0015] The beneficial effects of this utility model are:

[0026] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.
[0027] against Figure 3 This embodiment provides a dense mesh stamping die for forming dense mesh holes on a product. Please refer to [link / reference]. Figure 1 and Figure 2 As shown, the mold includes an upper mold base 1 and a lower mold base 2. An upper fixed plate 3 is provided on the upper mold base 1, and several punches 4 are provided on the upper fixed plate 3. The length of each punch 4 is different. A lower fixed plate 5 is provided on the lower fixed plate 2, and a die plate 6 is provided on the lower fixed plate 5. The die plate 6 has die holes 7 corresponding to each punch 4. A pressure plate 8 is provided between the upper fixed plate 3 and the die plate 6. The pressure plate 8 is used to press the product to be punched on the die plate 6 when the mold is closed and to help the product be unloaded when the mold is opened.
[0028] Therefore, by setting the heights of the various punches 4, some punches 4 are stamped first and some punches 4 are stamped later during the stamping process, which ensures that the product does not deform during stamping, has low vibration, low noise, and high product consistency. Moreover, all dense mesh holes can be formed in one mold closing, which improves the production cycle and reduces production costs.
[0029] Optionally, adjacent punches 4 have different lengths. This design allows adjacent mesh openings to be stamped sequentially during the processing of dense mesh, effectively preventing product deformation and ensuring the forming effect.
[0030] Optionally, the length of the punch 4 decreases sequentially from the center to the edge of the product. This design not only optimizes the stamping sequence but also ensures the stability of the product edges, further improving punching accuracy and overall quality.
[0031] Optionally, a number of positioning blocks 9 are provided on the lower fixing plate 5 and around the concave template 6. The positioning blocks 9 are used to limit the outer edge of the product.
[0032] Therefore, by using multiple positioning blocks 9 to limit the external movement of the product, displacement of the product during the stamping process is prevented, thereby further improving stamping accuracy and product qualification rate.
[0033] Optionally, the recessed template 6 is provided with at least two positioning pins 10, which are used to lock the position of the product.
[0034] Therefore, the product position is locked by the positioning pin 10, which further ensures the stability of the product position during the stamping process.
[0035] Optionally, a spring 11 is provided between the pressure plate 8 and the upper mold base 1, and an equal-height sleeve 12 is provided on the upper mold base 1 to limit the lower stroke of the pressure plate 8.
[0036] Therefore, through the elastic force of spring 11, the pressure plate 8 can adapt to the product thickness when the mold is closed, ensuring uniform clamping force, further optimizing the stamping effect, and improving the surface flatness of the product. At the same time, the equal height sleeve 12 restricts the downward stroke of the pressure plate 8, ensuring the normal stroke of the pressure plate 8.
[0037] Optionally, an inner guide post 13 is provided on the upper fixing plate 3, and an inner guide sleeve 14 that cooperates with the inner guide post 13 is provided on the lower fixing plate 5.
[0038] Thus, the precise fit between the inner guide post 13 and the inner guide sleeve 14 ensures accurate alignment between the punch 4 and the die hole 7.
[0039] Optionally, an outer guide post 15 is provided on the upper mold base 1, and an outer guide sleeve 16 that cooperates with the outer guide post 15 is provided on the lower mold base 2.
[0040] Therefore, the precise cooperation between the outer guide post 15 and the outer guide sleeve 16 ensures the stability of the relative position of the upper die holder 1 and the lower die holder 2, thus avoiding lateral displacement during the stamping process.
[0041] Optionally, limit posts 17 are provided on the upper mold base 1 and the lower mold base 2 respectively, and the limit posts 17 of the upper mold base 1 and the limit posts 17 of the lower mold base 2 abut against each other when the mold is closed.
[0042] Therefore, by having the upper and lower limit posts 17 abut against each other, the mold closing accuracy is ensured, excessive extrusion is prevented, the mold and product are further protected, and the safety and reliability of the overall operation are improved.
[0043] Optionally, a lower support plate 18 is provided below the lower mold base 2, and a pad 19 is provided between the lower support plate 18 and the lower mold base 2.
[0044] Therefore, by adjusting the height of the lower mold base 2 using the pad 19, it is ensured that the mold can be accurately aligned with workpieces of different heights, and the support strength of the lower mold base 2 is improved, thereby further enhancing molding accuracy and product quality.
[0045] Detailed operation process:
[0046] ① In the initial mold opening state, the pressure plate 8 is pushed out by the spring 11 and limited by the equal height sleeve 12; the inner guide post 13 and the inner guide sleeve 14 cooperate to form a guide; the pressure plate 8 is not in contact with the concave mold plate 6; the product to be punched is placed on the concave mold plate 6;
[0047] ② As the upper die holder 1 moves downward, the pressure plate 8 and the concave die 6 cooperate to press the product, the spring 11 is compressed to provide clamping force, the punch 4 gradually contacts the product, and the stamping begins;
[0048] ③ When the upper mold base 1 finishes moving, the upper and lower limit posts 17 come into contact, and the mold is locked in place;
[0049] ④ As the upper mold base 1 is lifted, the pressure plate 8 pushes the product out of the punch 4 under the action of the spring 11, which facilitates unloading and completes the forming of all the dense mesh holes of a product.
[0050] In summary, the aforementioned dense mesh punching die offers good adjustability. Addressing issues such as deformation due to dense punching, mechanical vibration, excessive noise, long production cycle time, and poor consistency, the die 4 is designed with varying heights. During the punching process, some punches 4 punch first, while others punch later, effectively controlling product deformation, mechanical vibration, excessive noise, long production cycle time, and poor consistency. Furthermore, the die operates reliably, produces consistent and high-quality finished products, facilitates demolding and product removal from the mechanism, and features a simple structure that is easy to operate, debug, and maintain, thus promoting standardization and automation.
