Description

Technical Field

[0001] This utility model relates to the field of molding technology, and more specifically to a multi-station progressive molding die for antenna springs. Background Technology

[0002] With increasing user demands, smartphones and other electronic devices are integrating more and more antennas, enabling them to have excellent signal transmission and reception capabilities. Current electronic devices typically use a metal area on the casing (such as a metal frame) as the antenna radiator. The circuit board inside the device contains antenna springs, which elastically contact the metal area of ​​the casing to transmit and receive antenna signals. A multi-station progressive forming die for antenna springs is an advanced stamping die used to produce antenna springs. It can complete multiple processes within a single die, including punching, bending, and forming. The principle is as follows: after the strip or bar material is fed into the die, under strict control of the step pitch accuracy, it is continuously punched at each station according to the forming process sequence. After punching or cutting at the final station, an antenna spring that meets the product requirements is produced. For example, in some mobile phone antenna spring stamping progressive dies, the strip material sequentially passes through stations such as pre-cutting, edge trimming, bulging, multiple bending, and shaping, gradually forming the required antenna spring.

[0003] For example, a novel antenna spring forming mold with prior art publication number CN221559551U uses a limiting disc to compress the first spring and damper, so that the antenna spring can accurately return to its original position after stamping. This maintains the positional accuracy and consistency during the stamping process, improves production efficiency, helps ensure operational safety, and avoids the risk of accidental injury or equipment damage caused by improper or misoperated operation by operators.

[0004] However, the existing technology has the following problems in use: During production, the antenna spring material slides directly on the surface of the lower mold base when being fed into the traditional molding die. Over time, this leads to unevenness on the surface of the lower mold base, which can easily affect the subsequent molding accuracy. Replacing the entire lower mold base would significantly increase costs. Based on this, this utility model provides a multi-station progressive molding die for antenna springs. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a multi-station progressive forming mold for antenna springs. The upper mold base and the lower mold base cooperate to achieve the progressive forming of antenna springs. A feeding box is added to guide the stable movement of materials, improve the forming accuracy, and facilitate individual replacement without the need to replace the entire lower mold base, thus reducing maintenance costs. In addition, the receiving box can classify and store waste materials, which helps to reduce resource waste and solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station progressive forming mold for antenna spring pieces, including a base, a lower mold base fixedly provided on the top of the base, an upper mold base provided on the top of the lower mold base, a plurality of equally spaced mounting slots opened on the top of the upper mold base, and a stamping die detachably fixed inside each mounting slot, a rectangular groove opened on the top of the lower mold base, a feeding box provided inside the rectangular groove, a feeding port opened at the bottom of the feeding box, a receiving groove opened at the front end of the lower mold base, a receiving box provided inside the receiving groove, and a feeding hole corresponding to the feeding port opened on the top of the receiving groove.

[0007] In a preferred embodiment, the receiving box is provided with a plurality of equally spaced partitions inside, which divide the inside of the receiving box into a plurality of spaces, each space corresponding to a plurality of discharge holes, so as to facilitate the classified storage of waste materials from different processes.

[0008] In a preferred embodiment, the feeding box has two symmetrically distributed threaded holes on both the front and rear sides, and the lower mold base has fastening bolts corresponding to the threaded holes on both the front and rear sides. The fastening bolts are threadedly connected to the threaded holes, which facilitates the subsequent disassembly and replacement of the feeding box.

[0009] In a preferred embodiment, two symmetrically distributed mounting holes are provided on both the front and rear sides of the lower mold base. The fastening bolts are located inside the mounting holes to prevent them from protruding outwards and loosening due to collisions with objects, thereby improving the fastening performance of the fastening bolts.

[0010] In a preferred embodiment, the bottom wall of the rectangular groove is fixed with a plurality of evenly distributed insert rods, and the top of the feeding box is provided with insert holes corresponding to the insert rods. The insert rods are inserted into the insert holes, and the insert rods and insert holes cooperate to facilitate the quick installation of the feeding box by the staff.

[0011] In a preferred embodiment, a top plate is fixedly provided on the top of the base, and the top plate is sleeved on the outside of the upper mold base and the lower mold base. An electric push rod is fixedly provided at the center of the top of the top plate, and the bottom end of the piston rod of the electric push rod is fixed to the top of the upper mold base. The upper mold base and the stamping die are moved together by the electric push rod, thereby improving the forming efficiency.

[0012] In a preferred embodiment, positioning rods are fixedly provided at the four corners of the top of the lower mold base, and positioning holes corresponding to the positioning rods are opened on the top of the upper mold base. The top of the positioning rod passes through the positioning hole and extends to the outside of the positioning hole. With the cooperation of the positioning rod and the positioning hole, the stability of the upper mold base during lifting can be effectively improved, thereby improving the molding accuracy.

[0013] The technical effects and advantages of this utility model are as follows: This invention achieves the gradual forming of antenna spring pieces through the cooperation of an upper mold base and a lower mold base. A feeding box is added to the top of the lower mold base, which not only guides the material to move stably and improves the forming accuracy, but also facilitates individual replacement without the need to replace the entire lower mold base, effectively reducing maintenance costs. In addition, waste materials generated from multiple forming processes can fall into the receiving box through the feeding port and feeding hole. At the same time, multiple partitions inside the box can achieve classified storage, which helps to reduce resource waste. Attached Figure Description

[0016] 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.

[0017] Refer to the instruction manual appendix Figures 1-5 This utility model provides a multi-station progressive forming mold for antenna springs, including a base 1, a lower mold base 2 fixedly provided on the top of the base 1, an upper mold base 3 provided on the top of the lower mold base 2, a plurality of equally spaced mounting slots 4 opened on the top of the upper mold base 3, and a stamping die 5 can be detachably fixed inside each mounting slot 4, a rectangular groove 6 opened on the top of the lower mold base 2, a feeding box 7 provided inside the rectangular groove 6, and a feeding port 8 opened at the bottom of the feeding box 7.

[0018] The lower mold base 2 has a storage groove 9 at its front end. The storage groove 9 has a material receiving box 10 inside. The top of the storage groove 9 has a material discharge hole 11 corresponding to the material discharge port 8. The material receiving box 10 has multiple equally spaced partitions 12 fixed inside. The multiple partitions 12 divide the inside of the material receiving box 10 into multiple spaces, and the multiple spaces correspond one-to-one with the multiple material discharge holes 11.

[0019] The base 1 is fixedly provided with a top plate 18, which is sleeved on the outside of the upper mold base 3 and the lower mold base 2. An electric push rod 19 is fixedly provided at the center of the top of the top plate 18, and the bottom end of the piston rod of the electric push rod 19 is fixed to the top of the upper mold base 3.

[0020] In actual production, the antenna spring material is fed in from the left side of the feeding box 7. When it moves to the position of the first stamping die 5, it pauses. Then, the electric push rod 19 drives the upper die base 3 and the stamping die 5 to press down and stamp the antenna spring material. After stamping, the upper die base 3 rises back, and the antenna spring material continues to be moved in the feeding box 7 to the next forming station for stamping again. This process is repeated step by step through multiple forming processes, and finally the finished antenna spring is output from the right side of the feeding box 7. The feeding box 7 can not only maintain the stable delivery of the antenna spring material, but also reduce the wear of the antenna spring material on the lower die base 2. At the same time, only the feeding box 7 needs to be replaced, without replacing the entire lower die base 2, thereby reducing maintenance costs. Furthermore, the waste generated during the stamping process can fall into the receiving box 10 through the feeding port 8 and the feeding hole 11, and be classified and stored by multiple partitions 12 set in the receiving box 10. After the work is completed, the operator can take the receiving box 10 out of the storage tank 9, which facilitates the centralized recycling of waste and reduces resource waste.

[0021] Refer to the instruction manual appendix Figure 1 and Figure 5 The feeding box 7 has two symmetrically distributed threaded holes 13 on both the front and rear sides. The lower mold base 2 has fastening bolts 14 corresponding to the threaded holes 13 on both the front and rear sides. The fastening bolts 14 are threaded to the threaded holes 13. The lower mold base 2 has two symmetrically distributed mounting holes 15 on both the front and rear sides. The fastening bolts 14 are located inside the mounting holes 15. In addition, a plurality of evenly distributed insert rods 16 are fixed on the bottom wall of the rectangular groove 6. The feeding box 7 has a corresponding insertion hole 17 on the top, and the insert rod 16 is inserted into the insertion hole 17.

[0022] The feeding box 7 is fixed by fastening bolts 14 to ensure its stability. The feeding box 7 can be removed by loosening multiple fastening bolts 14. When the worker installs the feeding box 7, he only needs to align the insertion hole 17 on the feeding box 7 with the insertion rod 16 and then tighten the fastening bolts 14.

[0023] like Figure 1 and Figure 4 As shown, positioning rods 20 are fixedly provided at the four corners of the top of the lower mold base 2. The top of the upper mold base 3 is provided with positioning holes 21 corresponding to the positioning rods 20. The top of the positioning rods 20 passes through the positioning holes 21 and extends to the outside of the positioning holes 21. With the cooperation of the positioning rods 20 and the positioning holes 21, the stability of the upper mold base 3 during lifting can be effectively improved, thereby improving the molding accuracy.

[0024] In conclusion, 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.
