Technical Field

[0001] The present application relates to the field of molds, and in particular, to a forming and punching mold for a casing product. Background Art

[0002] A casing refers to the external protective structure of a mechanical device or an electronic device, which is mainly made of metal, plastic or other synthetic materials and is used to protect the components inside the device from damage by the external environment.

[0003] Referring to Figure 1 , in the prior art, the casing includes a ring portion 13 and a plate portion 14. The outer wall of the circumferential portion of the plate portion 14 is coaxially fixed inside the inner circumferential wall of the ring portion 13 to form a fixation. A plurality of mounting holes 141 are spaced apart on the surface of the plate portion 14. The axes of the mounting holes 141 are parallel to the axis of the ring portion 13, and the mounting holes 141 penetrate through the outer wall of the plate portion 14 along their own axes.

[0004] The casing is mainly formed by stamping a block with a mold, and the mounting holes 141 are produced by punching the casing with a punching mold. When the height of the ring portion 13 is too high, the surface of the ring portion 13 is prone to cracking when the mold punches the block, thereby reducing the production efficiency of the casing. Summary of the Invention

[0005] In order to improve the problem that the surface of the ring portion of the mold punching block is prone to cracking, the present application provides a forming and punching mold for a casing product.

[0006] In a first aspect, a forming mold for a casing product provided by the present application adopts the following technical solution: A forming mold for a casing product includes a lower mold and a pressing mold. The pressing mold includes a sliding portion and a stamping portion. The sliding portion is slidably connected to the surface of the lower mold, and the stamping portion is connected to the end face of the sliding portion facing the lower mold. When the lower mold and the pressing mold are closed, a cavity for the punching block is left between the stamping portion and the lower mold. A guiding surface is provided on the end face of the stamping portion located in the cavity. The inclined height of the guiding surface decreases as the distance from the axis of the stamping portion decreases. The guiding surface guides the surface of the block to be stamped to form a ring portion.

[0007] By adopting the above technical solution, during the processing of the casing, the block is placed on the surface of the lower mold facing the stamping portion. The sliding portion slides towards the direction close to the lower mold. The lower mold and the pressing mold are closed to form a cavity. The stamping portion stamps the block in the cavity to form a casing. The inclined height of the guiding surface decreases as the distance from the axis of the stamping portion decreases, so that there is a certain slope between the end face of the stamping portion and the inner wall of the lower mold. The guiding surface guides the surface of the block to be stamped to form a ring portion, so that the flow rate of the block is stable when it is subjected to stamping, ensuring that the surface of the formed ring portion is not prone to cracking, thereby improving the production quality of the casing.

[0008] Optionally, the lower die includes a fixing portion and a demolding portion. The sliding portion is slidably connected to the surface of the fixing portion. The cavity is located between the fixing portion and the stamping portion. A demolding cavity for the demolding portion to slide is formed on the end face of the fixing portion facing the cavity. The demolding cavity penetrates the surface of the fixing portion. When the block is stamped in the cavity to form the casing, the demolding portion slides along the inner wall of the demolding cavity towards the cavity, and the surface of the demolding portion abuts against the surface of the casing and pushes the casing out of the cavity.

[0009] By adopting the above technical solution, when the stamping portion stamps the block in the cavity to form the casing, the sliding portion slides away from the lower die, and the pressing effect of the stamping portion on the casing disappears, driving the demolding portion to slide along the inner wall of the demolding cavity towards the cavity. The end face of the demolding portion abuts against the surface of the casing and pushes the casing out of the cavity, realizing the demolding of the casing, thereby improving the production efficiency of the casing.

[0010] Optionally, a positioning gap is left between the inner wall of the demolding cavity close to the cavity and the end face of the demolding portion. The end of the block is embedded in the positioning gap, and the inner wall of the positioning gap abuts against the end face of the block to form positioning.

[0011] By adopting the above technical solution, the block is placed in the positioning gap, and the end face of the block abuts against the inner wall of the positioning gap to form positioning, so that the block is not easily displaced on the end face of the lower die, thereby ensuring the stability of the stamping portion stamping the block to form the casing, and thus improving the production efficiency of the casing.

[0012] Optionally, a plurality of guide posts are spacedly connected to the surface of the fixing portion facing the sliding portion, and a plurality of guide sleeves are spacedly connected to the surface of the sliding portion facing the fixing portion. The guide posts and the guide sleeves correspond one by one and are slidably connected to the inner wall of the guide sleeves.

[0013] By adopting the above technical solution, when the sliding portion approaches or moves away from the fixing portion, the guide posts slide along the inner wall of the guide sleeves, and the inner wall of the guide sleeves abuts against the outer wall of the guide posts to form a limit, so that the guide posts are not easily displaced when sliding along the inner wall of the guide sleeves, thereby improving the sliding stability of the sliding portion on the surface of the fixing portion.

[0014] In a second aspect, a punching die for a casing product provided by the present application adopts the following technical solution: A punching die for a casing product, used for processing the casing product by a forming die, comprises a punching die and a fixed die, the fixed die comprises a limiting portion and a plurality of mounting portions, the end of the limiting portion is provided for a ring portion to be sleeved, a plurality of mounting portions are connected at intervals on the end face of the limiting portion, the end face of the mounting portion abuts against the end face of a plate portion, the punching die is slidably connected to the surface of the limiting portion, the punching die is provided with a plurality of stamping cavities spaced apart toward the end face of the limiting portion, the stamping cavities correspond one-to-one to the mounting portions, the stamping cavities are provided for the ends of the mounting portions to be embedded, when the ring portion is sleeved on the end of the limiting portion and the end face of the mounting portion abuts against the end face of the plate portion, the punching die approaches the fixed die and closes the die, a mounting hole is formed on the surface of the stamping plate portion of the mounting portion and is embedded in the stamping cavity.

[0015] By adopting the above technical scheme, when it is necessary to punch holes in the casing, the ring portion is sleeved on the end face of the limiting portion, and the inner wall of the ring portion abuts against the outer peripheral surface of the limiting portion to form a limit, thereby fixing the casing on the limiting portion; at the same time, the end face of the mounting portion away from the limiting portion abuts against the surface of the plate portion, and the mounting portion corresponds to the position of the preset punching holes of the plate portion one by one, driving the die close to the fixed die and closing the die, the end face of the die abuts against the surface of the plate portion and drives the plate portion close to the limiting portion along the axis of the mounting portion, and at the same time, the mounting portion stamps the surface of the plate portion to form mounting holes and embeds them into the stamping cavity, thereby completing the one-time punching of multiple mounting holes of the plate portion, thereby further improving the production efficiency of the casing.

[0016] Optionally, the limiting portion is connected to a stripping assembly, which includes a stripping plate and a guide rod. The limiting portion is provided with a guide cavity for the guide rod to slide on the end face facing the die, and the sliding direction of the guide rod and the sliding direction of the die are parallel to each other. The end face of the guide rod close to the mounting portion is connected to the stripping plate surface, and a plurality of avoidance cavities are spaced apart on the end face of the stripping plate, which correspond to the mounting portion one by one, and the mounting portion is passed through the avoidance cavities, and the stripping plate surface can abut against the plate surface.

[0017] By adopting the above technical scheme, when the ring portion is sleeved on the end portion of the limiting portion, the end face of the stripping plate is away from the guide rod and abuts against the plate surface of the plate portion, the die slides in the direction close to the limiting portion and closes the die, the end face of the die and the plate surface of the stripping plate clamp the two sides of the plate portion and drive the plate portion to slide along the axis of the mounting portion in the direction close to the limiting portion, the end face of the mounting portion punches the plate surface of the plate portion to form a mounting hole and embeds it into the stamping cavity, thereby realizing one-time stamping of multiple mounting holes of the casing; at the same time, the die slides in the direction away from the limiting portion, the tightening effect of the die on the casing disappears, driving the guide rod to slide along the inner wall of the guide cavity in the direction close to the mounting portion, driving the stripping plate to slide along the axis of the mounting portion in the direction away from the limiting portion, pushing the casing to separate from the mounting portion along the axis of the mounting portion, thereby realizing the unloading of the casing.

[0018] Optionally, the stripping component further includes an elastic member and a conduction plate. A conduction cavity for the conduction plate to slide is formed on the inner wall of the guiding cavity away from the stripping plate. The sliding direction of the conduction plate is parallel to the sliding direction of the guiding rod. The end face of the guiding rod away from the stripping plate abuts against the plate face of the conduction plate. One end of the elastic member in the direction of its elastic force is connected to the inner wall of the conduction cavity, and the other end of the elastic member in the direction of its elastic force abuts against the plate face of the conduction plate. The elastic member has an elastic force to drive the conduction plate to slide towards the guiding cavity, and there is a tendency for the plate face of the stripping plate to be flush with the surface of the installation part.

[0019] By adopting the above technical solution, when the punching die slides away from the limiting part, the pressing effect of the punching die on the casing disappears. The elastic force of the elastic member drives the conduction plate to slide along the inner wall of the conduction cavity towards the guiding cavity. The end face of the conduction plate away from the elastic member abuts against the end face of the guiding column, driving the guiding column to slide along the inner wall of the guiding cavity towards the installation part, driving the stripping plate to abut against the end face of the plate part and driving the casing to slide along the axis of the installation part away from the limiting part, realizing automatic stripping of the casing, thereby improving the production efficiency of the casing.

[0020] Optionally, the punching die is connected with a blanking component. The blanking component includes a blanking plate and a plurality of blanking rods. A force application cavity is formed on the end face of the punching die away from the fixed die. A blanking cavity for the blanking plate to slide is formed on the inner wall of the force application cavity close to the stamping cavity. The blanking cavity communicates with a plurality of stamping cavities. One ends of the plurality of blanking rods are connected to the plate face of the blanking plate at intervals, and the other ends of the plurality of blanking rods are respectively embedded in the stamping cavities.

[0021] By adopting the above technical solution, when the end face of the punching die abuts against the end face of the plate part and drives the plate part to slide along the axis of the installation part towards the limiting part, the end of the installation part punches the surface of the plate part to form an installation hole and embeds it into the stamping cavity, driving the waste generated by stamping the plate part into the stamping cavity. When the punching die slides away from the limiting part, the end of the installation part disengages from the stamping cavity. The force application cavity drives the blanking plate to slide along the inner wall of the blanking cavity towards the stamping cavity, driving the blanking rods to abut against the waste along the inner wall of the stamping cavity and slide towards the installation part, pushing the waste out of the stamping cavity, realizing automatic cleaning of the inner wall of the stamping cavity.

[0022] Optionally, a first step surface is formed at the connection between the force application cavity and the blanking cavity, and a second step surface is formed at the connection between the blanking cavity and the stamping cavity. When the plate face of the blanking plate abuts against the first step surface, the end of the installation part is embedded in the stamping cavity. When the plate face of the blanking plate abuts against the second step surface, the end of the blanking rod protrudes from the end face of the punching die.

[0023] By adopting the above technical solution, when the end of the installation part is embedded in the stamping cavity, the surface of the blanking plate abuts against the first step surface to form positioning, making it difficult for the operator to apply excessive force; when the surface of the blanking plate abuts against the second step surface, the end face of the blanking rod protruding from the punching die can abut against the surface of the plate part, and the surface of the blanking rod and the surface of the installation part abut tightly against both sides of the plate part to form a limit, so that the plate part is not prone to deviation when stamping to generate the installation hole, thereby improving the processing accuracy of the casing.

[0024] Optionally, a plurality of guide posts are connected at intervals to the end face of the fixed die facing the punching die, and a plurality of guide sleeves are connected at intervals to the end face of the punching die facing the fixed die. The guide posts and the guide sleeves correspond one by one and are slidably connected to the inner wall of the guide sleeve.

[0025] By adopting the above technical solution, when the punching die approaches or moves away from the fixed die, it drives the guide post to slide on the inner wall of the guide sleeve. The inner wall of the guide sleeve abuts against the outer peripheral surface of the guide post to form a limit, making it difficult for the guide post to deviate on the inner wall of the guide sleeve, thereby improving the sliding stability of the punching die.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of the lower die and the pressing die makes there be a certain slope between the end face of the stamping part and the inner wall of the lower die. The guiding surface guides the surface of the block to stamp and form a ring part, making the flow velocity of the block stable when being stamped, ensuring that the surface of the formed ring part is not prone to cracking, thereby improving the production quality of the casing; 2. The setting of the fixing part and the demolding part drives the demolding part to slide along the inner wall of the demolding cavity towards the direction close to the cavity. The end face of the demolding part abuts against the surface of the casing and pushes the casing out of the cavity, realizing the demolding of the casing, thereby improving the production efficiency of the casing; 3. The setting of the positioning gap makes the block not prone to deviation on the end face of the lower die, thereby ensuring the stability of the stamping part stamping the block to form the casing, and thus improving the production efficiency of the casing.

Detailed implementation manners

[0035] The following further describes the present application in detail Figure 2-7 in conjunction with the attached drawings.

[0036] The embodiment of the present application discloses a forming die for a casing product. Refer to Figure 2 and Figure 3 , a forming die for a casing product includes a lower die 1 and a pressing die 2. The lower die 1 includes a fixing part 11 and a demolding part 12. A demolding cavity 111 for the demolding part 12 to slide is provided on the top surface of the fixing part 11. The sliding direction of the demolding part 12 is parallel to the height direction of the fixing part 11. A plurality of guiding columns 3 are fixedly arranged at intervals on the top surface of the fixing part 11. The plurality of guiding columns 3 are evenly distributed at intervals around the axis of the demolding part 12. The pressing die 2 includes a sliding part 21 and a stamping part 22. A plurality of guiding sleeves 4 are fixedly arranged at intervals on the end surface of the sliding part 21. The guiding sleeves 4 correspond to the guiding columns 3 one by one. The guiding columns 3 are slidably connected to the inner wall of the guiding sleeves 4. The inner wall of the guiding sleeves 4 abuts against the outer wall of the guiding columns 3 to form a limit, ensuring the stability of the sliding of the sliding part 21.

[0037] Refer to Figure 2 and Figure 3, the stamping part 22 is detachably connected to the end face of the sliding part 21 facing the demolding part 12. When the lower mold 1 and the pressing mold 2 are closed, there is a cavity 23 for stamping the block body between the stamping part 22 and the fixing part 11. The end face of the stamping part 22 located in the cavity 23 is provided with a guiding surface 221, and the inclined height of the guiding surface 221 decreases as the distance from the axis of the stamping part 22 decreases. The guiding surface 221 guides the pressed block body to flow to form the ring part 13; the demolding cavity 111 communicates with the cavity 23, and there is a positioning gap 112 between the inner wall of the demolding cavity 111 close to the cavity 23 and the end face of the demolding part 12. The positioning gap 112 is for the end part of the block body to be embedded, and the inner wall of the positioning gap 112 abuts against the end face of the block body to form a limit, so that the block body is not prone to shift on the inner wall of the cavity 23, thereby improving the stability of the stamping part 22 stamping the block body to form the casing.

[0038] Referring to Figure 2 and Figure 3 , when the block body is embedded in the positioning gap 112, the end face of the block body abuts against the inner wall of the positioning gap 112 to form a limit, realizing the limit of the block body on the fixing part 11; at the same time, the sliding part 21 is driven to approach the fixing part 11, and the guiding column 3 slides along the inner wall of the guiding sleeve 4, improving the stability of the sliding of the sliding part 21. The lower mold 1 and the pressing mold 2 are closed, and the stamping part 22 extrudes the block body in the cavity 23 to form the casing. The inclined height of the guiding surface 221 decreases as the distance from the axis of the stamping part 22 decreases, so that there is a certain slope between the end face of the stamping part 22 and the inner wall of the lower mold 1. The guiding surface 221 guides the surface of the block body to be stamped to form the ring part 13, so that the flow rate of the block body is stable when it is pressed and flows, ensuring that the surface of the formed ring part 13 is not prone to cracking, thereby improving the production quality of the casing; when the stamping of the casing in the cavity 23 is completed, the sliding part 21 is driven to move away from the fixing part 11, and the pressing effect of the stamping part 22 on the casing disappears. The demolding part 12 is driven to slide along the inner wall of the demolding cavity 111 towards the direction close to the cavity 23, and the end face of the demolding part 12 abuts against the surface of the casing and pushes the casing out of the cavity 23, realizing the demolding of the casing, thereby improving the production efficiency of the casing.

[0039] The implementation principle of the forming mold of a casing product in an embodiment of the present application is as follows: during the production of the casing, the block body is embedded in the positioning gap 112, and the end face of the block body abuts against the inner wall of the positioning gap 112 to form a limit, realizing the limit of the block body on the fixing part 11; at the same time, the sliding part 21 is driven to approach the fixing part 11, and the guiding column 3 slides along the inner wall of the guiding sleeve 4, improving the stability of the sliding of the sliding part 21. The lower mold 1 and the pressing mold 2 are closed, and the stamping part 22 extrudes the block body in the cavity 23 to form the casing. The inclined height of the guiding surface 221 decreases as the distance from the axis of the stamping part 22 decreases, so that there is a certain slope between the end face of the stamping part 22 and the inner wall of the lower mold 1. The guiding surface 221 guides the surface of the block body to be stamped to form the ring part 13, so that the flow rate of the block body is stable when it is pressed and flows, ensuring that the surface of the formed ring part 13 is not prone to cracking, thereby improving the production quality of the casing.

[0040] The embodiment of the present application also discloses a punching die for a casing product. Refer to Figure 4 and Figure 5 , a punching die for a casing product includes a punching die 5 and a fixed die 6. The fixed die 6 includes a limiting portion 61 and a plurality of mounting portions 62. The end of the limiting portion 61 is sleeved with the ring portion 13. The outer peripheral surface of the limiting portion 61 abuts against the inner circumferential wall of the ring portion 13 to form a limit, realizing the fixation of the casing on the limiting portion 61. One ends of the plurality of mounting portions 62 are fixedly spaced on the end surface of the limiting portion 61. The other ends of the plurality of mounting portions 62 can abut against the plate surface of the plate portion 14. The mounting portions 62 correspond to the positions of the preset mounting holes 141 of the plate portion 14 one by one. A plurality of guide posts 7 are connected to the end surface of the limiting portion 61 at intervals. The axes of the guide posts 7 and the axes of the mounting portions 62 are parallel to each other. A plurality of guide sleeves 8 are connected to the end surface of the punching die 5 facing the fixed die 6 at intervals. The guide posts 7 and the guide sleeves 8 correspond to each other one by one. The guide posts 7 are slidably connected to the inner wall of the guide sleeves 8. The inner wall of the guide sleeves 8 abuts against the outer wall of the guide posts 7 to form a limit, thereby improving the stability of the sliding of the punching die 5.

[0041] Refer to Figure 5 and Figure 6 , the end of the punching die 5 facing the mounting portion 62 can be embedded into the inner cavity of the ring portion 13. The outer peripheral surface of the punching die 5 abuts against the inner circumferential wall of the ring portion 13 to form a limit, so that the casing is not easily displaced on the limiting portion 61, thereby improving the limiting stability of the casing on the limiting portion 61; a plurality of punching cavities 51 are arranged at intervals on the end surface of the punching die 5 facing the mounting portion 62. The punching cavities 51 correspond to the mounting portions 62 one by one. The punching cavities 51 are for the ends of the mounting portions 62 to be embedded.

[0042] Refer to Figure 5 and Figure 6 , when one end in the axial direction of the ring portion 13 is sleeved on the end of the limiting portion 61, the end surface of the mounting portion 62 abuts against the plate surface of the plate portion 14, driving the punching die 5 to approach the limiting portion 61. The end of the punching die 5 is embedded into the other end in the axial direction of the ring portion 13. At the same time, the end surface of the punching die 5 and the surface of the mounting portion 62 clamp both sides of the plate portion 14. The punching die 5 continues to approach the limiting portion 61. The mounting portion 62 punches the surface of the plate portion 14 to form the mounting holes 141 and is embedded into the punching cavities 51. At the same time, the waste generated by grooving the plate portion 14 enters the punching cavities 51, realizing the one-time punching processing of the plurality of mounting holes 141 on the casing.

[0043] Refer to Figure 5 and Figure 7, a stripping component 9 is installed on the limiting part 61. The stripping component 9 can push the punched casing away from the installation part 62. The stripping component 9 includes a stripping plate 91, a guide rod 92, an elastic member 93 and a conduction plate 94. A guide cavity 611 for the guide rod 92 to slide is formed on the end face of the limiting part 61 facing the punching die 5. The sliding direction of the guide rod 92 is parallel to the axis of the installation part 62. The end face of the guide rod 92 in the axial direction close to the installation part 62 is fixed on the plate surface of the stripping plate 91. A plurality of avoidance cavities 911 are spaced apart on the plate surface of the stripping plate 91. The depth direction of the avoidance cavity 911 is parallel to the axis of the installation part 62. The avoidance cavity 911 penetrates through the plate surface of the stripping plate 91 along its own depth direction. The avoidance cavity 911 corresponds to the installation part 62 one by one, and the end of the installation part 62 passes through the avoidance cavity 911.

[0044] Refer to Figure 5 and Figure 7 , the number of the elastic members 93 can be one, two or more. In the embodiment of the present application, the number of the elastic members 93 is multiple. The elastic members 93 can be compression springs or tension springs. In the embodiment of the present application, the elastic members 93 are compression springs and have a certain deformation ability. A conduction cavity 612 for the conduction plate 94 to slide is formed on the inner wall of the guide cavity 611 far from the stripping plate 91. The sliding direction of the conduction plate 94 is parallel to the axis of the installation part 62. One end in the elastic force direction of the elastic member 93 is connected to the inner wall of the conduction cavity 612 far from the guide cavity 611, and the other end in the elastic force direction of the elastic member 93 abuts against the plate surface of the conduction plate 94. The elastic member 93 and the guide column 3 abut against both ends of the conduction plate 94 in the axial direction. The elastic member 93 has an elastic force to drive the conduction plate 94 to slide towards the direction close to the guide cavity 611, and there is a tendency that the plate surface of the stripping plate 91 is flush with the surface of the installation part 62.

[0045] Refer to Figure 5 and Figure 6 , when the installation hole 141 is formed on the surface of the plate part 14 by stamping the installation part 62 and is embedded in the stamping cavity 51, the plate surface of the stripping plate 91 and the surface of the punching die 5 clamp both sides of the plate part 14 to form a limit. The punching die 5 is far from the limiting part 61, and the pressing effect of the punching die 5 on the plate part 14 disappears. The elastic force of the elastic member 93 drives the conduction plate 94 to slide towards the direction close to the guide cavity 611, drives the guide column 3 to slide along the inner wall of the guide cavity 611 towards the direction close to the installation part 62. The plate surface of the stripping plate 91 abuts against the surface of the plate part 14 and drives the plate part 14 away from the sliding part 21. The installation hole 141 of the installation part 62 on the stripping plate 91 part is used to realize the automatic blanking of the casing, thereby improving the processing efficiency of the casing.

[0046] Refer to Figure 5 and Figure 6The punching die 5 is connected with a blanking assembly 10, which can clean up the waste in the stamping cavity 51. The blanking assembly 10 includes a blanking plate 101 and a plurality of blanking rods 102. A force-applying cavity 52 is provided on the end face of the punching die 5 away from the limiting portion 61. A blanking cavity 53 for sliding of the blanking plate 101 is provided on the inner wall of the force-applying cavity 52 close to the stamping cavity 51. The sliding direction of the blanking plate 101 and the axis of the mounting portion 62 are parallel to each other. The blanking cavity 53 connects the plurality of stamping cavities 51. One ends of the plurality of blanking rods 102 are connected to the surface of the blanking plate 101 at intervals. The other ends of the plurality of blanking rods 102 correspond to and are embedded in the plurality of stamping cavities 51 one by one. The blanking rods 102 are slidably connected to the inner wall of the stamping cavity 51, and the sliding direction of the blanking rods 102 and the axis of the mounting portion 62 are parallel to each other.

[0047] Reference Figure 5 and Figure 6 A step surface 1 54 is formed at the connection between the blanking cavity 53 and the force-applying cavity 52, and a step surface 2 55 is formed at the connection between the blanking cavity 53 and the stamping cavity 51. When the surface of the blanking plate 101 abuts against the step surface 2 55, the end of the blanking rod 102 protrudes out of the end face of the die 5, driving the die 5 to approach the limiting portion 61, and the rod surface of the blanking rod 102 and the surface of the mounting portion 62 clamp the two sides of the plate portion 14 to form a limit. The die 5 continues to approach the limiting portion 61, and the mounting portion 62 forms a mounting hole 141 on the surface of the stamping plate portion 14 and is embedded in the stamping cavity 51. The mounting portion 62 drives the blanking rod 102 to slide along the inner wall of the stamping cavity 51 toward the blanking cavity 53, driving the surface of the blanking plate 101 to abut against the step surface 1 54 to form a limit, so that the staff is not easy to apply excessive pressure, thereby improving the production efficiency of the casing.

[0048] Reference Figure 5 and Figure 6 When the mounting hole 141 on the casing is punched, the die 5 is driven away from the limiting portion 61, and the end of the mounting portion 62 is separated from the stamping cavity 51. The blanking plate 101 is driven to slide toward the stamping cavity 51 through the force-applying cavity 52, driving the blanking rod 102 to move away from the force-applying cavity 52 along the inner wall of the stamping cavity 51. The blanking rod 102 drives the waste generated by the punching of the casing to separate from the stamping cavity 51, thereby realizing automatic cleaning of the inner wall of the stamping cavity 51.

[0049] The implementation principle of a punching die for a casing product in an embodiment of the present application is as follows: When it is necessary to punch the plate portion 14 to form the mounting hole 141, one end in the axial direction of the ring portion 13 is sleeved on the end of the limiting portion 61, the end face of the mounting portion 62 abuts against the plate surface of the plate portion 14, the punching die 5 is driven to approach the limiting portion 61, the end of the punching die 5 is embedded in the other end in the axial direction of the ring portion 13. At the same time, the end face of the punching die 5 and the surface of the mounting portion 62 clamp both sides of the plate portion 14. The punching die 5 continues to approach the limiting portion 61, the mounting portion 62 punches the surface of the plate portion 14 to form the mounting hole 141 and embeds it into the punching cavity 51. At the same time, the waste generated by slotting the plate portion 14 enters the punching cavity 51, realizing the one-time punching processing of multiple mounting holes 141 on the casing.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
