Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically, to a stamping die for the outer stripes of a bowl-shaped part. Background Technology

[0002] Stamping dies are special tools used in stamping processes to apply pressure to metal or non-metal sheets, causing them to undergo plastic deformation or separation, thereby obtaining workpieces with specific shapes, sizes, and properties.

[0003] Currently, some existing stamping dies for producing bowl-shaped knobs typically require placing the product on the lower die core before using the upper die core to stamp the outer stripes. As a result, after the stamping operation is completed, the upper die core leaves the product, which is then attached to the outer wall of the lower die core, making it difficult for workers to pick it up.

[0004] To address the aforementioned issues, this application proposes a stamping die for the outer stripes of a bowl-shaped part. Utility Model Content

[0005] To address the problems in related technologies, this utility model provides a stamping die for the outer stripes of a bowl-shaped part, which can stably eject the processed product through three sets of ejector pins, making it convenient for workers to handle.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A stamping die for outer stripes of a bowl-shaped part includes a lower die base, a lower die body at the upper end of the lower die base, a die core seat installed in the inner cavity of the lower die body, a lower die core body at the upper end of the die core seat, an upper die assembly above the lower die core body, three sets of ejection through holes evenly distributed in the inner cavity of the lower die core body, and a positioning through hole that cooperates with the ejection through holes in the inner cavity of the die core seat. An ejector pin body passes through both the ejection through hole and the positioning through hole. The bottom end of the ejector pin body is installed on the top of the ejector block, and an ejector rod is connected to the bottom end of the ejector block.

[0007] As a further embodiment of this utility model, the upper mold assembly includes an upper mold body, an upper mold core body is installed in the inner cavity of the upper mold body, an upper mold base is provided at the upper end of the upper mold body, and an upper equipment base is installed at the upper end of the upper mold base by bolts.

[0008] As a further embodiment of this utility model, a lower equipment seat is bolted to the bottom of the lower mold base, and a channel is provided in the middle of the lower equipment seat, through which an ejector rod slides.

[0009] As a further embodiment of this utility model, the ejector block is slidably connected to the ejector through groove in the inner cavity of the lower mold base.

[0010] As a further embodiment of this utility model, the top end of the ejector through hole is located on the outer wall of the upper section of the lower mold core body.

[0011] As a further embodiment of this utility model, the number of ejector pin bodies corresponds to the number of ejector through holes, and there are three sets of each, with the three sets of ejector pin bodies evenly distributed on the top of the ejector block.

[0012] The beneficial effects of this utility model are as follows: This invention utilizes a combination of a lower die core, an ejector through-hole, a positioning through-hole, an ejector block, and an ejector rod. When stamping is complete and the upper die core separates from the lower die core, the ejector rod moves upward under the influence of the stamping equipment. This, in turn, causes the ejector block to move upward within the ejector through-groove. This causes the three sets of ejector pins on the block to move upward within the positioning and ejector through-holes until they pass through the top of the ejector through-holes, thus ejecting the processed product from the lower die core. This allows the stamping die to stably eject the processed product using the three sets of ejector pins, making it convenient for workers to handle. Attached Figure Description

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] According to an embodiment of the present invention, a stamping die for outer stripes of a bowl-shaped part is provided.

[0018] Please refer to the instruction manual appendix. Figure 1-6 According to an embodiment of the present invention, a stamping die for outer stripes of a bowl-shaped part includes a lower die base 1, a lower die body 2 disposed at the upper end of the lower die base 1, a die core seat 3 installed in the inner cavity of the lower die body 2, a lower die core body 4 disposed at the upper end of the die core seat 3, an upper die assembly 5 disposed above the lower die core body 4, and three sets of ejection through holes 6 evenly distributed in the inner cavity of the lower die core body 4, the top of the ejection through holes 6 being located on the outer wall of the upper section of the lower die core body 4. The inner cavity of 3 is also provided with a positioning through hole 7 that is used in conjunction with the ejection through hole 6. The ejection through hole 6 and the positioning through hole 7 are both through which ejector pin bodies 8 are inserted. The bottom end of the ejector pin body 8 is installed on the top of the ejector block 9. The bottom end of the ejector block 9 is connected to an ejector rod 10. The ejector block 9 is slidably connected to the ejection through groove 13 in the inner cavity of the lower mold base 1. The number of ejector pin bodies 8 corresponds to the ejection through hole 6, and there are three sets of each. The three sets of ejector pin bodies 8 are evenly distributed on the top of the ejector block 9. In the above technical solution, the lower die core body 4, ejection through hole 6, positioning through hole 7, ejection block 9 and ejection rod 10 work together. When the stamping is completed and the upper die core body 52 leaves the lower die core body 4, the ejection rod 10 moves upward under the drive of the stamping equipment, which in turn drives the ejection block 9 to move upward in the ejection through groove 13. This causes the three sets of ejector pin bodies 8 on it to move upward in the positioning through hole 7 and ejection through hole 6 until the three sets of ejector pin bodies 8 pass through the top of the ejection through hole 6, thus ejecting the processed product away from the lower die core body 4. This allows the stamping die to stably eject the processed product through the three sets of ejector pin bodies 8, making it convenient for workers to pick up.

[0019] In one embodiment, please refer to the appendix to the specification. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The upper die assembly 5 includes an upper die body 51, an upper die core body 52 installed in the inner cavity of the upper die body 51, and an upper die base 53 provided at the upper end of the upper die body 51. An upper equipment base 54 is bolted to the upper end of the upper die base 53. The upper die core body 52 works in conjunction with the lower die core body 4 to facilitate stamping operations, while the upper die base 53 facilitates the installation of the upper die assembly 5.

[0020] In one embodiment, please refer to the appendix to the specification. Figure 1 , Figure 2 and Figure 6 The lower mold base 1 has a lower equipment seat 11 bolted to its bottom, and a channel 12 is provided in the middle of the lower equipment seat 11, through which the ejector rod 10 slides. The lower mold base 1 and the lower equipment seat 11 facilitate the installation of the entire lower mold assembly, while the channel 12 in the middle of the lower equipment seat 11 facilitates the operation of the ejector rod 10.

[0021] The ejector pin body 8 is made of high-speed steel with surface hardening treatment to prevent deformation or wear. The top of the ejector through hole 6 has a gap from the upper surface of the lower mold core body, and the axis is radially distributed at 120° with the axis of the lower mold core body. The three sets of ejector pins are evenly stressed to prevent product deformation. There is a fit clearance between the ejector block 9 and the ejector through groove 13, and between the ejector pin body 8 and the positioning through hole 7 to ensure smooth sliding and prevent jamming or oil leakage. The upper end of the lower mold core body 4 is provided with an annular positioning step. The diameter of the step is adapted to the inner diameter of the product to be processed to ensure that the product does not deviate during stamping and the forming accuracy meets the standard. The ejector rod 10 is driven by the pneumatic ejector mechanism or hydraulic ejector mechanism of the stamping equipment. The ejection speed is adjustable to avoid damage to the product due to excessive ejection.

[0022] Workflow: First, install all components of the stamping die into the predetermined positions on the stamping equipment. During operation, place the product to be processed onto the lower die body 4. Then, the upper die assembly 5 moves downward under the drive of the stamping equipment, allowing the upper die body 52 to stamp the product to be processed on the lower die body 4. After completion, the upper die body 52 leaves the lower die body 4, and the ejector rod 10 moves upward under the drive of the stamping equipment. This causes the ejector block 9 to move upward within the ejection slot 13, causing the three sets of ejector pin bodies 8 on it to move upward within the positioning through hole 7 and the ejection through hole 6 until the three sets of ejector pin bodies 8 pass through the top of the ejection through hole 6, thus ejecting the processed product away from the lower die body 4. The worker can then remove the product.

[0023] It should be noted that the working principle of the stamping equipment used in stamping dies is well known to those skilled in the art, and therefore will not be elaborated upon.

[0024] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
