Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a rubber sheet mold that avoids the formation of hole waste during rubber sheet mold operation. Background Technology

[0002] The products cut by the rotary die-cutting machine include plastic sheets, copper foil, aluminum foil, zinc foil and stainless steel foil. In the operation of plastic sheet molds, the problem of hole waste (such as waste material residue after punching, mold jamming, mold wear, etc.) is a common pain point affecting production efficiency and product quality.

[0003] For example, Chinese patent CN217318346U discloses a plastic sheet mold that avoids the formation of hole waste during plastic sheet mold operation. This utility model avoids the generation of small hole waste during die cutting, thereby solving the technical problem of inconvenience in subsequent operations caused by small hole waste.

[0004] However, existing plastic sheet molds that avoid hole waste during plastic sheet mold operation can only be used for products of specific thicknesses. When processing plastic sheets or metal foils of different thicknesses, the positioning gap can easily cause die-cutting deviation. In addition, although small hole waste is avoided, a small amount of edge waste may be generated during the die-cutting process, such as the leftover material after product cutting. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a rubber sheet mold that avoids the formation of hole waste during rubber sheet mold operation, in order to solve the problems mentioned above. Utility Model Content

When processing plastic sheets or metal foils of different thicknesses, it is easy to cause die-cutting deviation due to positioning gap. In addition, although it avoids small hole waste, a small amount of edge waste may be generated during the die-cutting process, such as the leftover material after product cutting. Therefore, there is still room for further improvement.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the plastic sheet mold that avoids the formation of hole waste during plastic sheet mold operation, through the rotation of the threaded rod driving the connecting frame to move, the connecting frame driving the upper template to adjust synchronously, changing the distance between the upper template and the plastic sheet body, adapting to products such as plastic sheets and metal foils of different thicknesses, avoiding die-cutting offset caused by positioning gaps, and reducing the generation of hole waste; the staff can observe the accumulation of waste in the collection tank in real time through the viewing window, which is convenient for timely cleaning of waste and ensures the continuous and efficient operation of the collection mechanism; 1. It is equipped with an upper positioning plate, positioning pins and positioning holes.

[0019] 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.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a rubber sheet mold that avoids the formation of hole waste during rubber sheet mold operation, comprising: an upper fixed plate 1, an upper template 2, a die-cutting blade 3, an upper positioning plate 4, a positioning post 5, a connecting frame 6, a limiting hole 7, a limiting post 8, a threaded rod 9, a lower fixed plate 10, a lower positioning plate 11, a positioning hole 12, a rubber sheet body 13, a limiting plate 14, a cutting hole 15, a collection hole 16, a collection groove 17, a viewing window 18, a limiting block 19, a spring 20, and a sliding groove 21.

[0021] Existing plastic sheet molds that avoid hole waste during plastic sheet mold operation can only be used for products of specific thicknesses. When processing plastic sheets or metal foils of different thicknesses, the positioning gap can easily cause die-cutting misalignment. In addition, although small hole waste is avoided, a small amount of edge waste may be generated during the die-cutting process, such as the leftover material after product cutting. Therefore, there is still room for further improvement.

[0022] When using a plastic sheet mold that avoids the formation of holes and waste during plastic sheet mold operations, such as Figure 1 , Figure 2 and Figure 3 As shown, before performing the die-cutting operation, the die spacing is first adjusted according to the thickness of the product to be processed, such as plastic sheet or metal foil. Rotating the threaded rod 9, since it is threadedly connected to the upper fixed plate 1, the threaded rod 9 moves along its own axis when rotated. Simultaneously, the threaded rod 9 is rotatably connected to the connecting frame 6, thereby pushing the connecting frame 6 to slide inside the upper fixed plate 1. The limiting hole 7 inside the connecting frame 6 slides in engagement with the limiting post 8 fixed on the upper fixed plate 1. The limiting post 8 limits the movement direction of the connecting frame 6, preventing it from shifting. The connecting frame 6 drives the connected upper template 2 to move synchronously until the distance between the die-cutting blade 3 on the lower side of the upper template 2 and the rubber sheet body 13 on the lower fixed plate 10 matches the product thickness, completing the adjustment.

[0023] like Figure 1 , Figure 4 and Figure 5As shown, the product to be processed is placed on the plastic plate body 13. The limiting plate 14 on the upper side of the plastic plate body 13 positions the product to prevent it from shifting during the die-cutting process. The die-cutting equipment is started, and the upper fixing plate 1 moves the upper template 2 downwards. Simultaneously, the positioning pins 5 on the lower side of the upper positioning plate 4 are inserted into the positioning holes 12 on the lower positioning plate 11, achieving precise positioning of the upper and lower molds and ensuring that the die-cutting blade 3 is accurately aligned with the cutting hole 15 on the plastic plate body 13. As the upper template 2 continues to move downwards, the die-cutting blade 3 passes through the product and inserts into the cutting hole 15, completing the die-cutting. Edge waste generated during the die-cutting process falls into the collection groove 17 inside the lower fixing plate 10 through the corresponding collection holes 16 on the plastic plate body 13 and the lower fixing plate 10 under the die-cutting pressure.

[0024] like Figure 5 As shown, the collection trough 17 is tightly fitted with the sliding groove 21 inside the lower fixed plate 10. Under the elastic action of the spring 20, the sliding groove 21 always remains in contact with the collection trough 17. One end of the spring 20 is fixed to the limiting block 19, which is fixed on the lower fixed plate 10, ensuring the stable installation of the collection trough 17 and preventing it from shifting during die-cutting vibration. The operator can observe the accumulation of waste material in the trough through the viewing window 18 on the right side of the collection trough 17. When the waste material reaches a certain amount, the spring 20 is compressed, pulling the collection trough 17 outward. The collection trough 17 slides along the sliding groove 21 until it detaches from the lower fixed plate 10. After cleaning the waste material, the collection trough 17 is pushed back into the sliding groove 21, and the spring 20 returns to its original position, completing the reset and installation of the collection trough 17 for subsequent waste collection.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
