Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a horizontal stamping die for producing the lower cover of VC tablets. Background Technology

[0002] Stamping dies are a commonly used process equipment in industrial production. They utilize the internal cavity and punch of the die to process metal or non-metal materials into parts of the desired shape through pressure. Stamping dies have advantages such as high production efficiency, high material utilization, and high machining accuracy, and are widely used in industries such as automobiles, electronics, and home appliances. With the advancement of technology and industrial development, the requirements for stamping dies are becoming increasingly stringent. They not only need to meet basic processing requirements but also need to possess characteristics such as high precision, high efficiency, and high stability.

[0003] A vapor chamber (VC) is an important component for heat dissipation, widely used in mobile phones, computers, servers, graphics cards, etc., to dissipate heat. A VC vapor chamber typically consists of an upper and lower cover, both made of metal sheets, forming a vacuum cavity, usually made of copper. Its working principle is based on the gas-liquid phase change principle: when heat is applied to one side of the cavity, the working liquid inside absorbs heat and evaporates rapidly, expanding in volume quickly, and the gaseous cooling medium rapidly fills the entire cavity. The vapor moves to a cooler area under a small pressure difference, where it condenses into liquid and releases heat. Subsequently, the condensed coolant flows back to the heating area through microstructured capillary channels, completing the cycle. This process repeats continuously within the cavity, achieving efficient heat conduction and uniform distribution.

[0004] The existing VC chip lower cover stamping dies have the following defects:

[0005] 1) Traditional stamping dies often use multiple independent workstations to complete different processes, which not only increases production costs but also reduces production efficiency;

[0006] 2) Existing stamping dies are prone to causing deformation of the metal sheet substrate during processing. When the metal sheet is subjected to external force, it undergoes elastic deformation, which disappears when the external force is unloaded or released. However, due to the change in the stress state of the metal sheet during the forming process, the stress distribution inside the material becomes uneven. When the external force is unloaded or released, the metal sheet will experience stress release, resulting in springback deformation, which affects the quality and performance of the product. Utility Model Content

[0007] In order to overcome the shortcomings of existing technical solutions, this utility model provides a horizontal stamping die for producing the lower cover of VC sheet, which can effectively solve the technical problem that metal sheets that require multiple dies for stamping and forming are prone to springback and deformation.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A horizontal stamping die for producing the lower cover of a VC sheet includes a lower die base and an upper die base. A lower die assembly is provided at one end of the lower die base near the upper die base, and an upper die assembly corresponding to the lower die assembly is provided at one end of the upper die base near the lower die base. The lower die assembly is provided with a punching guide hole station, a rib punching station, a embossing station, a embossing station, a trimming station, and a part ejection station in sequence. The metal sheet substrate for processing enters the lower die assembly through a feeding mechanism and passes through the punching guide hole station, the rib punching station, the embossing station, the embossing station, the trimming station, and the part ejection station in sequence. The lower die assembly is provided with a processing channel for the metal sheet substrate to pass through, and the processing channel passes through the punching guide hole station, the rib punching station, the embossing station, the embossing station, the trimming station, and the part ejection station in sequence.

[0010] In the punching guide hole station, the upper die assembly includes a punching upper die and a punching bottom die is set on the lower die base. After the lower die base and the upper die base are closed, the punching upper die and the punching bottom die punch guide positioning holes on the metal sheet substrate. Each station is equipped with a guide rod corresponding to the guide positioning hole. After the lower die base and the upper die base are closed, the guide rod passes through the guide positioning hole.

[0011] In the rib punching station, the upper mold assembly includes a rib upper mold and the lower mold base includes a rib bottom mold. After the lower mold base and the upper mold base are closed, the rib upper mold and the rib bottom mold punch out rib strips on the metal sheet substrate. The rib strips are set on the outside of the lower cover of the product VC sheet. After the lower cover of the product VC sheet is separated from the metal sheet substrate, the rib strips remain on the metal sheet substrate.

[0012] Furthermore, in the part-making station, the upper mold assembly includes a double-sided punching upper mold, and the lower mold base includes a double-sided punching bottom mold. After the lower mold base and the upper mold base are closed, the double-sided punching upper mold and the double-sided punching bottom mold cut off the adjacent ends of the two VC sheet bottom covers arranged in front and behind on the metal sheet substrate. After cutting off the edges, the VC sheet bottom covers far from the cutting edge station in the part-making station are completely separated from the metal sheet substrate and removed from the part.

[0013] Furthermore, gaps are provided on both sides of the embossing station, which is close to the rib-making station and the embossing station.

[0014] Furthermore, the upper mold base and upper mold assembly also include an upper mold for embossing, an upper mold for packaging, and an upper mold for trimming. The lower mold base is provided with a lower mold for embossing, a lower mold for packaging, and a lower mold for trimming. After the mold is closed, the upper mold for embossing and the lower mold for embossing punch out the embossing of the VC sheet lower cover and the water inlet on the metal sheet substrate. The upper mold for packaging and the lower mold for packaging press and shape the embossing of the VC sheet lower cover and the water inlet. The upper mold for trimming and the lower mold for trimming separate part of the edge of the VC sheet lower cover from the metal sheet substrate.

[0015] Furthermore, the lower module also includes a guide plate and a floating block. The guide plates are symmetrically arranged on the lower mold base, and a processing channel is formed between the two symmetrically arranged guide plates. The floating block is disposed in the processing channel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The stamping station, rib punching station, embossing station, embossing station, embossing station, trimming station, and part ejection station are integrated into one stamping die, realizing continuous stamping processing of metal sheet substrates. This greatly improves production efficiency, simplifies the production process, and reduces the time spent on multiple clamping and transfers, thereby saving production time and reducing production costs. At the same time, since all stations are completed in one die, the consistency and accuracy of processing are also guaranteed, improving the quality and stability of the product. The stamping station is equipped with a rib punching station. By punching guide positioning holes on the metal sheet substrate, the guide positioning holes are used to ensure the accurate alignment of the metal sheet substrate at each station, thereby avoiding processing errors caused by misalignment, improving processing accuracy, and ensuring the continuity and stability of subsequent station processing.

[0018] 2) A rib punching station is provided. By punching ribs on the edge of the metal sheet substrate, the structural strength of the metal sheet substrate is effectively enhanced, preventing deformation of the metal sheet substrate due to stress release during the stamping process. The ribs are used to strengthen the edge part of the metal sheet substrate during stamping, thereby improving its resistance to deformation. After stamping, the ribs remain on the metal sheet substrate and do not affect the structural design of the VC sheet cover of the product. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] The following is combined Figures 1-4 The present invention provides a detailed description of the horizontal stamping die for producing the lower cover of VC tablets:

[0026] The horizontal stamping die for the VC sheet lower cover includes a lower die base 1 and an upper die base 2. A lower die assembly 3 is provided at one end of the lower die base 1 near the upper die base 2, and an upper die assembly 4 corresponding to the lower die assembly 3 is provided at one end of the upper die base 2 near the lower die base 1. The lower die assembly 3 is provided with a punching guide hole station 5, a rib punching station 6, a embossing station 7, a embossing station 8, a trimming station 9, and a part ejection station 10 in sequence. The metal sheet substrate 12 used for processing enters the lower die assembly 3 through a feeding mechanism and passes through the punching guide hole station 5, the rib punching station 6, the embossing station 7, the embossing station 8, the trimming station 9, and the part ejection station 10 in sequence. The lower die assembly 3 is provided with a processing channel for the metal sheet substrate 12 to pass through, and the processing channel passes through the punching guide hole station 5, the rib punching station 6, the embossing station 7, the embossing station 8, the trimming station 9, and the part ejection station 10 in sequence. By integrating the punching guide hole station 5, the rib punching station 6, the embossing station 7, the embossing station 8, the trimming station 9, and the part ejection station 10 into a single stamping die, continuous stamping processing of the metal sheet substrate 12 is achieved. This greatly improves production efficiency, simplifies the production process, reduces the time spent on multiple clamping and transfer operations, and saves production time and reduces production costs. At the same time, since all stations are completed in one die, the consistency and precision of the processing are ensured, thereby improving the quality and stability of the product.

[0027] In the punching guide hole station 5, the upper die group 4 includes a punching upper die 401 and a punching bottom die on the lower die base 1. After the lower die base 1 and the upper die base 2 are closed, the punching upper die 401 and the punching bottom die punch guide positioning holes 1201 on the metal sheet substrate 12. Each station is provided with a guide rod 303 corresponding to the guide positioning hole 1201. After the lower die base 1 and the upper die base 2 are closed, the guide rod 303 passes through the guide positioning hole 1201. The punching guide hole station 5 is set up. By punching guide positioning holes 1201 on the metal sheet substrate 12, the guide positioning holes 1201 are used to ensure the accurate alignment of the metal sheet substrate 12 at each station, thereby avoiding processing errors caused by misalignment, improving the accuracy of processing, and ensuring the continuity and stability of subsequent processing stations.

[0028] In the rib-making station 6, the upper mold assembly 4 includes a rib upper mold 402, and the lower mold base 1 includes a rib bottom mold. After the lower mold base 1 and the upper mold base 2 are closed, the rib upper mold 402 and the rib bottom mold punch out rib strips 1202 on the edge of the metal sheet substrate 12. The rib-making station 6 is set up so that by punching out rib strips 1202 on the edge of the metal sheet substrate 12, the structural strength of the metal sheet substrate 12 is effectively enhanced, and the deformation of the metal sheet substrate 12 due to stress release during the stamping process is prevented. During the stamping process, the rib strips 1202 are used to strengthen the edge part of the metal sheet substrate 12, thereby improving its resistance to deformation. After the stamping is completed, the rib strips 1202 remain on the metal sheet substrate 12 and do not affect the structural design of the VC sheet lower cover 11 of the product.

[0029] In the part-making station 10, the upper die assembly 4 includes a double-sided punching upper die 406, and the lower die base 1 includes a double-sided punching bottom die. After the lower die base 1 and the upper die base 2 are closed, the double-sided punching upper die 406 and the double-sided punching bottom die trim the adjacent ends of the two VC sheet lower covers 11 arranged front to back on the metal sheet substrate 12. After trimming, the VC sheet lower covers 11 away from the trimming station 9 on the part-making station 10 are completely separated from the metal sheet substrate 12, further optimizing the stamping process. Through the cooperation of the double-sided punching upper die 406 and the double-sided punching bottom die, it is possible to trim the two VC sheet lower covers 11 arranged front to back in one stamping. The front and rear trimming of the VC sheet lower covers 11 are achieved through the same set of dies.

[0030] Spacer gaps 13 are provided on both sides of the embossing station 7, near the rib-forming station 6 and the full-embossing station 8. These gaps prevent the metal sheet substrate 12 from being stamped during mold closing, helping to reduce friction and interference between materials during stamping and improving stamping accuracy and stability. Simultaneously, the gaps 13 also provide space for mold maintenance and adjustment, facilitating subsequent mold upkeep and repair.

[0031] The upper mold base 2 and the upper mold assembly 4 also include an upper mold for embossing 403, an upper mold for packaging 404, and an upper mold for trimming 405. The lower mold base 1 is provided with a bottom mold for embossing, a bottom mold for packaging, and a bottom mold for trimming. After the mold is closed, the upper mold for embossing 403 and the bottom mold for embossing punch out the embossing 1102 and the water inlet 1101 of the VC sheet lower cover 11 on the metal sheet substrate 12. The upper mold for packaging 404 and the bottom mold for packaging press and shape the embossing 1102 and the water inlet 1101 of the VC sheet lower cover 11. The upper mold for trimming 405 and the bottom mold for trimming separate part of the edge of the VC sheet lower cover 11 from the metal sheet substrate 12.

[0032] The lower die assembly 3 also includes a guide plate 301 and a floating block 302. The guide plates 301 are symmetrically arranged on the lower die base 1, forming a processing channel between the two symmetrically arranged guide plates 301. The floating block 302 is disposed in the processing channel, which helps to guide the metal sheet substrate 12 smoothly through each station during the stamping process, while reducing the deformation and damage of the material during the stamping process. The combined use of the guide plate 301 and the floating block 302 can further improve the accuracy and stability of stamping, ensuring the quality and performance of the final product.

[0033] Stamping process: The long metal sheet substrate 12 is inserted into the processing channel through the feeding mechanism. At the punching guide hole station 5, the metal sheet substrate 12 is punched out with guide positioning holes 1201. After completion, the feeding mechanism pushes the metal sheet substrate 12 forward. At the rib punching station 6, the metal sheet substrate 12 punches out rib strips 1202 around the area of ​​the formed VC sheet lower cover 11. After completion, it enters the first interval station 13, waiting to punch out the rib strips 1202 in the next forming area before entering the embossing station 7. At the embossing station 7, the metal sheet substrate 12 is punched out with embossing 1102 and water injection port 1101. After embossing is completed, it enters the second interval station 13 to wait, and then... The VC sheet lower cover 11 enters the convex shaping station 8, where the convex shaping station 8 shapes the convex 1102 and the water inlet 1101 on the metal sheet substrate 12 to ensure that the convex 1102 and the water inlet 1101 on the VC sheet lower cover 11 have the same shape. Then it enters the edge trimming station 9, where the edge trimming station 9 separates the left and right sides of the VC sheet lower cover 11 from the metal sheet substrate 12. Finally, it is stamped twice more at the parting station 10. The first time, the end of the VC sheet lower cover 11 away from the edge trimming station 9 is punched and cut with the metal sheet substrate 12. The second time, the end of the VC sheet lower cover 11 close to the edge trimming station 9 is punched and cut with the metal sheet substrate 12, so that the VC sheet lower cover 11 is completely separated from the metal sheet substrate 12 and the part is completed.
