Description

Technical Field

[0001] This application relates to the field of mold technology, and more specifically, to an automatic centering structure for an inner ball cage forging separation mold. Background Technology

[0002] The inner ball cage forging separation die is a special die used in the forging process of inner ball cages, which are key components of mechanical transmission systems such as automobiles. Its main function is to accurately and efficiently separate the inner ball cage forging from excess flash, connecting skin, and other auxiliary materials after the forging process is completed, through specific structural design and reasonable mechanical transmission, so as to obtain the inner ball cage forging finished product with dimensional accuracy and surface quality that meets the requirements, thereby meeting the needs of subsequent processing and assembly, and improving production efficiency and product quality stability.

[0003] A search revealed that patent CN213613612U discloses a mold structure for automatic in-mold material alignment, including a top seat. A hydraulic cylinder is fixedly connected to the center of the top seat, and guide pillars are fixedly connected to both sides of the bottom end of the top seat. Each guide pillar is fitted with a spring, and a base plate is connected to the lower end of the four guide pillars. The bottom ends of the four guide pillars are respectively fixedly connected to the four corners of the upper end of the base plate. A lower mold is fixedly connected to the center of the upper end of the base plate. An inner cavity is opened in the center of the base plate, and a lead screw is installed in the inner cavity. Both ends of the lead screw are threadedly connected to moving blocks. The beneficial effects are: it drives the object to be processed on the placement plate to move, so that the position to be stamped is aligned with the mold hole of the lower mold. It can automatically align the object with the mold hole, which is very convenient and accurate. By setting the placement plate, the part of the object to be processed to be punched is aligned with the mold hole. The two ends of the object to be processed are placed on the two placement plates, so that the two sides of the object on the placement plate are limited, reducing the offset, the stamping position is accurate, and the stamping effect is better.

[0004] Although the aforementioned patent limits the two sides of the placed plate to reduce displacement, in actual use, it can only limit the two sides of the lower mold. It is difficult to limit the other two sides. This can easily cause the lower mold to shift or make errors due to incomplete positioning when under force, thus affecting the accuracy of mold production and the service life of the mold.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figures 1-5The automatic centering structure of the inner ball cage forging separation mold includes a mold body 1, an upper mold base 2 on one side of the mold body 1, a lower mold base 3 on one side of the mold body 1, a cavity 4 inside the mold body 1, and an automatic centering component inside the cavity 4.

[0029] The automatic alignment component includes alignment plates 9, and the number of alignment plates 9 is set to two. The two alignment plates 9 are located on both sides of the upper mold base 2 and the lower mold base 3, respectively. A first cylinder 5 is fixedly connected to one side of the cavity 4. The first cylinder 5 is used to drive the two alignment plates 9 to automatically align the upper mold base 2 and the lower mold base 3.

[0030] Reference Figures 1-5 The first cylinder 5 is located on the inner bottom wall of the cavity 4. The output end of the first cylinder 5 is fixedly connected to a support plate 6. The two sides of the support plate 6 are rotatably connected to first rotating shafts 11. The outer walls of the two ends of the two first rotating shafts 11 are rotatably connected to connecting rods 8. The top two sides of the cavity 4 are provided with two sliding grooves 13. The bottom of the two centering plates 9 are fixedly connected with two connecting seats 10. Each connecting seat 10 is slidably connected to the corresponding sliding groove 13. The bottom of each centering plate 9 is provided with a second rotating shaft 12. Each connecting seat 10 is rotatably connected to the corresponding second rotating shaft 12. The top of each connecting rod 8 is rotatably connected to the outer wall of the corresponding second rotating shaft 12. The side of each centering plate 9 near the upper mold base 2 is provided with a limiting groove 14. The top two sides of each limiting groove 14 are provided with alignment holes 15. The two ends of the upper mold base 2 are provided with alignment blocks 7. The structure of each alignment block 7 is adapted to the structure of the corresponding alignment hole 15. Each alignment block 7 is slidably connected to the corresponding limiting groove 14.

[0031] The automatic centering component prevents the upper die holder 2 from shifting during stamping, achieving automatic centering. Specifically, before the separation process of the inner ball cage forging begins, the output end of the first cylinder 5 retracts, pulling the support plate 6 downwards. The support plate 6 drives the first rotating shafts 11 on both sides to rotate, causing the connecting rod 8 to rotate around the first rotating shaft 11. Because the top of the connecting rod 8 is rotatably connected to the second rotating shaft 12 at the bottom of the centering plate 9, and the connecting seat 10 at the bottom of the centering plate 9 can slide within the slide groove 13, under the pull of the connecting rod 8, the two centering plates 9 move closer to the center along the slide groove 13. As the centering plates 9 approach the upper die holder 2, the alignment blocks 7 on both sides of the upper die holder 2 precisely insert into the alignment holes 15 at the top of the corresponding centering plate 9 limiting groove 14, completing the precise centering of the upper die holder 2 on the mold body 1. After centering, the stamping process begins, and the upper die holder 2 can stamp vertically downwards along the limiting groove 14, effectively preventing shifting and ensuring the separation accuracy of the inner ball cage forging.

[0032] The automatic alignment component enables precise positioning of the upper die holder 2 and the lower die holder 3 before stamping, avoiding problems such as substandard separation dimensions and burrs caused by manual alignment errors or die misalignment. This improves the dimensional accuracy and surface quality of the inner ball cage forgings. Furthermore, the component replaces manual intervention with mechanical automation, significantly shortening alignment time, increasing production efficiency, and reducing labor intensity. At the same time, the stable alignment effect can reduce die wear caused by uneven stress, extend die life, and reduce production costs, providing a strong guarantee for the high-quality and large-scale production of inner ball cage forgings.

[0033] Reference Figures 1-5 Each centering plate 9 has a roller 16 on one side, and the number of rollers 16 is set to multiple, with the multiple rollers 16 being evenly distributed. A control panel 17 is provided on one side of the mold body 1, and a second cylinder 18 is provided on the top of the mold body 1. The output end of the second cylinder 18 passes through the top of the mold body 1 and is fixedly connected to the upper mold base 2.

[0034] By setting multiple rollers 16, the frictional resistance between the centering plate 9 and the upper mold base 2 and the lower mold base 3 can be effectively reduced, making the centering process smoother and reducing component wear.

[0035] By setting the control panel 17 and the second cylinder 18, the upper die holder 2 can be stably raised and lowered. Combined with the automatic centering structure, this further ensures the accuracy and reliability of the stamping process.

[0036] Working principle: Before the separation process of the inner ball cage forging is started, the output end of the first cylinder 5 retracts, pulling the support plate 6 downward. The support plate 6 drives the first rotating shafts 11 on both sides to rotate, so that the connecting rod 8 rotates with the first rotating shaft 11 as the fulcrum. Since the top of the connecting rod 8 is rotatably connected to the second rotating shaft 12 at the bottom of the centering plate 9, and the connecting seat 10 at the bottom of the centering plate 9 can slide in the slide groove 13, under the pull of the connecting rod 8, the two centering plates 9 move closer to the middle along the slide groove 13. As the centering plates 9 approach the upper die seat 2, the alignment blocks 7 on both sides of the upper die seat 2 are precisely inserted into the alignment holes 15 at the top of the limiting groove 14 of the corresponding centering plate 9, completing the precise centering of the upper die seat 2 on the die body 1. After the centering is completed, the stamping process is started, and the upper die seat 2 can be stamped vertically downward along the limiting groove 14, effectively avoiding deviation and ensuring the separation accuracy of the inner ball cage forging.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
