A slider-type hardware stamping die and process

Abstract

This invention relates to the field of stamping die technology, and discloses a slider-type hardware stamping die and process, including: a base, on which a bracket and a fixed die are fixedly installed, a hydraulic rod is fixedly installed on the bracket, and a moving die is fixedly installed at the movable end of the hydraulic rod. The moving die is located above the fixed die, and a first sliding groove is opened in the fixed die. When the die is separated, the side slider drives the sliding block to move. The sliding block cooperates with the roller through the first inclined edge, and drives the ejector rod to rise and eject the workpiece with the help of the preload of the first spring, realizing automatic material discharge. This avoids the problem of traditional molds requiring manual insertion to remove parts, which is prone to burns. At the same time, the groove width is greater than the insertion block width, ensuring that the ejector rod only lifts the workpiece after the side slider is completely away from the workpiece, avoiding component damage caused by the ejector rod lifting when the workpiece and the side slider are stuck. Through automatic material discharge and precise material discharge timing control, the operation safety and processing continuity are improved, and the failure rate is reduced.

Description

Technical Field

[0001] This invention relates to the field of stamping die technology, specifically to a slider-type hardware stamping die and process. Background Technology

[0002] Sliding block type stamping dies are a key piece of equipment widely used in the mass production of hardware parts. In the stamping process, the closing and opening action of the die is used to accurately stamp raw materials such as metal sheets into hardware products that meet the design specifications, thereby satisfying the diverse needs of different industries for hardware parts.

[0003] In traditional multi-workpiece stamping production, the blanking operation can only begin after the mold opening action is fully completed. This step-by-step blanking method makes the entire production process less smooth and continuous. Blanking each workpiece requires additional time to wait for mold opening, which greatly reduces the overall production efficiency. For dies with sliders, blanking can only begin after the side sliders are completely separated. In addition, existing slider dies usually add a locking mechanism to ensure the stability of slider movement during mold closing. However, in the subsequent blanking stage, the locking mechanism needs to be unlocked first, which requires specific operation steps and time, thus extending the total blanking time. Due to the reduced blanking efficiency, the entire stamping production cycle is lengthened. Based on this, the present invention aims to provide a slider-type hardware stamping die and process that can optimize the blanking process, reduce blanking restrictions, and improve stamping production efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a sliding block type stamping die and process for hardware parts, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A sliding block type stamping die for hardware parts, comprising:

[0007] A base is provided, on which a bracket and a fixed mold are fixedly mounted. A hydraulic rod is fixedly mounted on the bracket, and a moving mold is fixedly mounted on the movable end of the hydraulic rod. The moving mold is located above the fixed mold. A first sliding groove is provided in the fixed mold, and a stamping table is fixedly mounted on the fixed mold. The stamping table is used to place the workpiece. Two symmetrically arranged side sliders are slidably mounted in the first sliding groove. An inclined guide groove is provided on the top of the side sliders. A stamping rod and an inclined guide post are fixedly mounted on the bottom of the moving mold. The stamping rod corresponds to the stamping table, and the inclined guide post is slidably connected to the inclined guide groove. When the hydraulic rod drives the moving mold to descend, the inclined guide post inserts into the inclined guide groove, causing the two side sliders to move closer to each other. At this time, the stamping rod stamps the workpiece on the stamping table, and the two side sliders stamp the sides of the workpiece.

[0008] Two symmetrically arranged fixing blocks are fixedly installed on the fixed mold. The fixing blocks are connected to the side sliders by tension springs. The preload of the tension springs keeps the side sliders away from the workpiece.

[0009] The ejector pin passes through the fixed mold and the stamping table. The ejector pin is slidably installed in the fixed mold. The ejector pin is driven to rise and fall by a linkage component. The linkage component is connected to the side sliders. When the two side sliders move away from each other, the side sliders drive the ejector pin to rise through the linkage component.

[0010] As a further embodiment of the present invention: the linkage assembly includes a fixed plate, a first spring, rollers, sliding blocks, a first inclined side, and a locking assembly. The fixed plate is fixedly installed at the bottom end of the top rod. The two rollers are rotatably installed at both ends of the fixed plate. The bottom of the fixed plate is connected to the base through the first spring. The preload of the first spring causes the fixed plate to rise. The two sliding blocks are slidably installed in the first sliding groove. The sliding blocks are located below the side slider. The first inclined side is opened at the bottom end of the sliding block. The horizontal height of the end of the first inclined side near the top rod is higher than the horizontal height of the end of the first inclined side away from the top rod. The first inclined side slides in cooperation with the rollers. The top end of the sliding block is temporarily rigidly connected to the bottom end of the side slider through the locking assembly.

[0011] As a further embodiment of the present invention: the locking component includes a protrusion, a slot, a notch, and a plug. The notch is formed at the bottom end of the side slider, the protrusion is fixedly installed on the top end of the slider, the protrusion is slidably connected to the notch, the slot is formed on the protrusion, the notch has a groove, the plug is slidably installed in the groove, the plug is slidably connected to the slot, and the side of the plug facing the groove is connected to the bottom of the groove through a second spring. The preload of the second spring causes the plug to move away from the groove.

[0012] As a further aspect of the present invention: the locking assembly further includes a magnet and an electromagnet, one end of the insert block passes through the side slider, the magnet is fixedly connected to the end of the insert block located outside the side slider, a second slide groove is provided in the first slide groove, the magnet is slidably installed in the second slide groove, and the electromagnet is fixedly installed in the second slide groove. When the two side sliders move away from each other, the magnet on the side slider aligns with the electromagnet. At this time, the electromagnet is activated, driving the magnet to approach the electromagnet, causing the insert block to move into the groove, and the slider block is unlocked from the side slider.

[0013] As a further aspect of the present invention: a rack plate is slidably installed in the first groove, the rack plate is fixedly connected to the sliding block, a driving component is provided at the bottom of the fixed mold, the driving component is connected to the rack plate, when the sliding block is unlocked from the side slider, the driving component drives the two sliding blocks to move closer to each other, each of the inserts has a second inclined side at one end, the second inclined side is inclined, and the distance between the two second inclined sides increases along the direction close to the top rod, the second inclined side slides in cooperation with the edge of the protrusion.

[0014] As a further aspect of the present invention: the width of the slot is greater than the width of the insert block. When the moving mold and the fixed mold separate, causing the side slider to move away from the workpiece, the insert block and the slot slide together until the side slider is completely away from the workpiece and the insert block abuts against the side wall of the slot.

[0015] As a further embodiment of the present invention: the driving assembly includes a rotating shaft, a ratchet assembly, and a gear. The rotating shaft and the gear are rotatably mounted on the bottom of the fixed mold. The rotating shaft is driven to rotate by a driving source. The gear is sleeved on the rotating shaft and is coaxially arranged with the rotating shaft. The gear is connected to the rotating shaft through the ratchet assembly. The gear meshes with the rack plate. When the driving source drives the rotating shaft to rotate, the ratchet assembly is in a locked state. The rotating shaft drives the gear to rotate synchronously through the ratchet assembly. The gear drives the rack plate to move towards the ejector pin. When the moving mold and the fixed mold separate, causing the side slider to move away from the workpiece, the side slider drives the sliding block to move synchronously. The sliding block drives the gear to rotate through the rack plate. The ratchet assembly is in a sliding engagement state. At this time, the rotating shaft is stationary.

[0016] A stamping process for slider-type hardware parts, the process being applied to a slider-type hardware part stamping die as described above, the process comprising the following steps:

[0017] Step S1: First, place the workpiece on the stamping table;

[0018] Step S2: Then, the moving mold is driven down by the hydraulic rod to make the stamping rod stamp the stamping table. At the same time, the inclined guide post is inserted into the inclined guide groove to make the two side slides approach the workpiece, thereby stamping the side of the workpiece.

[0019] Step S3: During mold parting, the moving mold rises and the cooperation of the inclined guide post and the inclined guide groove causes the two side sliders to move away from the workpiece. At the same time, the tension spring will pull the side sliders away from the workpiece.

[0020] Step S4: When the side slider moves away from the workpiece, it will drive the push rod to rise through the linkage component, thereby pushing the stamped workpiece out of the stamping table and realizing automatic material discharge.

[0021] The beneficial effects of this invention are:

[0022] 1. In this invention, during mold parting, the side slider drives the sliding block to move. The sliding block cooperates with the roller through the first inclined side, and drives the ejector rod to rise and eject the workpiece with the help of the first spring preload, realizing automatic material discharge. This avoids the problem of manual insertion into the mold to remove the part, which is easy to be burned. At the same time, the slot width is greater than the insertion block width, ensuring that the ejector rod only lifts the workpiece after the side slider is completely away from the workpiece. This avoids the damage to the parts caused by the ejector rod lifting when the workpiece and the side slider are stuck. Through automatic material discharge and precise material discharge timing control, the operation safety and processing continuity are improved, and the failure rate is reduced.

[0023] 2. In this invention, when the moving mold descends, the vertical driving force of the hydraulic rod is converted into the horizontal moving force of the side slider through the sliding cooperation of the inclined guide post and the inclined guide groove. This allows the two side sliders to accurately approach the workpiece to achieve side stamping. When the side slider completes the stamping, it establishes a temporary rigid connection with the sliding block, which improves the stability of the side slider. The fixed block forms a pre-tight constraint on the side slider through the tension spring, which ensures that the initial position of the side slider is stable, further improving the positional accuracy during stamping and reducing the mold manufacturing cost and maintenance difficulty.

[0024] 3. In this invention, the temporary rigid connection between the sliding block and the side slider is achieved by locking the insert block of the locking component and engaging the slot, ensuring the stability of the side slider driving the sliding block to move synchronously. During mold parting, the electromagnet drives the magnet to make the insert block slide into the groove to complete the unlocking. After unlocking, the drive component drives the sliding block to reset and the ejector rod to retract, preparing for the next processing. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-8 As shown, the present invention is a slider-type hardware stamping die, comprising:

[0037] A base 1 is provided, on which a bracket 2 and a fixed mold 4 are fixedly installed. A hydraulic rod 3 is fixedly installed on the bracket 2. A movable mold 5 is fixedly installed at the movable end of the hydraulic rod 3. The movable mold 5 is located above the fixed mold 4. A first sliding groove 401 is provided in the fixed mold 4. A stamping table 6 is fixedly installed on the fixed mold 4. The stamping table 6 is used to place the workpiece. Two symmetrically arranged side sliders 7 are slidably installed in the first sliding groove 401. An inclined guide groove 701 is provided at the top of the side sliders 7. A stamping rod 8 and an inclined guide post 501 are fixedly installed at the bottom of the movable mold 5. The stamping rod 8 corresponds to the stamping table 6. The inclined guide post 501 is slidably connected to the inclined guide groove 701. When the hydraulic rod 3 drives the movable mold 5 to descend, the inclined guide post 501 inserts into the inclined guide groove 701, so that the two side sliders 7 move closer to each other. At this time, the stamping rod 8 stamps the workpiece on the stamping table 6, and the two side sliders 7 stamp the side of the workpiece.

[0038] Fixed blocks 10, two symmetrically arranged fixed blocks 10 are fixedly installed on the fixed mold 4. The fixed blocks 10 are connected to the side sliders 7 through tension springs 9. The preload of the tension springs 9 makes the side sliders 7 move away from the workpiece.

[0039] The ejector rod 11 passes through the fixed mold 4 and the stamping table 6. The ejector rod 11 is slidably installed in the fixed mold 4. The ejector rod 11 is driven to rise and fall by a linkage component. The linkage component is connected to the side slider 7. When the two side sliders 7 move away from each other, the side sliders 7 drive the ejector rod 11 to rise through the linkage component.

[0040] Specifically, the linkage assembly includes a fixed plate 12, a first spring 13, rollers 14, sliding blocks 15, a first inclined edge 16, and a locking assembly. The fixed plate 12 is fixedly installed at the bottom end of the top rod 11. The two rollers 14 are rotatably installed at both ends of the fixed plate 12. The bottom of the fixed plate 12 is connected to the base 1 via the first spring 13. The preload of the first spring 13 causes the fixed plate 12 to rise. The two sliding blocks 15 are slidably installed in the first slide groove 401. The sliding blocks 15 are located below the side slider 7. The first inclined edge 16 is opened at the bottom end of the sliding block 15. The horizontal height of the end of the first inclined edge 16 near the top rod 11 is higher than the horizontal height of the end of the first inclined edge 16 away from the top rod 11. The first inclined edge 16 is slidably engaged with the rollers 14. The top end of the sliding block 15 is temporarily rigidly connected to the bottom end of the side slider 7 via the locking assembly.

[0041] In one embodiment, it should be noted that the hydraulic rod 3 described in this invention is prior art, and this invention does not improve upon it. Therefore, it is not necessary to disclose its specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0042] The working principle of this invention is as follows: When a workpiece needs to be processed, it is first placed on the stamping table 6. The hydraulic rod 3 is activated, driving the moving mold 5 to descend vertically. The moving mold 5 drives the bottom stamping rod 8 and the inclined guide post 501 to descend synchronously. As the moving mold 5 continues to descend, the inclined guide post 501 first inserts into the inclined guide groove 701 at the top of the side slider 7. Since the inclined guide post 501 is slidably connected to the inclined guide groove 701, the descending force of the moving mold 5 is converted into a horizontal force that pushes the side slider 7 to slide along the first sliding groove 401, causing the two side sliders 7 to overcome the preload of the tension spring 9 and move closer to each other. During this process, the stamping rod 8 continues to descend with the moving mold 5 and contacts the workpiece on the stamping table 6, stamping the front of the workpiece; at the same time, the two side sliders 7 that are moving closer to each other contact the side of the workpiece, stamping the side of the workpiece, thus completing the multi-directional processing of the workpiece simultaneously.

[0043] After stamping, the mold parting stage begins. Hydraulic rod 3 drives moving mold 5 to rise. Moving mold 5 drives stamping rod 8 and inclined guide post 501 to rise synchronously. Inclined guide post 501 gradually disengages from the constraint of inclined guide groove 701. The preload of tension spring 9 pulls the two side sliders 7 away from each other along the first slide groove 401. When the side sliders 7 move away from the workpiece, because sliding block 15 and side sliders 7 are temporarily rigidly connected by a locking assembly, side sliders 7 will drive sliding block 15 to move synchronously along the first slide groove 401 away from ejector rod 11. The first inclined edge 16 at the bottom of sliding block 15 slides in cooperation with the rollers 14 rotatably mounted at both ends of fixed plate 12. Since the horizontal height of the end of the first inclined edge 16 near ejector rod 11 is higher than the end away from ejector rod 11, ... Figure 1 As shown in the example, when the mold is closed, the two first inclined sides 16 restrict the fixed plate 12 from moving upward under the action of the first spring 13. When the mold is opened, the sliding block 15 moves away from the ejector rod 11, causing the roller 14 to roll upward on the first inclined side 16. This is because the preload of the first spring 13 pushes the fixed plate 12 to rise, and the fixed plate 12 drives the ejector rod 11 to pass through the stamping table 6 and eject the workpiece, realizing automatic material discharge.

[0044] like Figures 1-8 As shown, in a preferred embodiment of the present invention, the locking assembly includes a protrusion 21, a slot 22, a notch 23, and a plug 25. The notch 23 is formed at the bottom end of the side slider 7. The protrusion 21 is fixedly installed on the top end of the slider block 15. The protrusion 21 is slidably connected to the notch 23. The slot 22 is formed on the protrusion 21. A groove 24 is formed in the notch 23. The plug 25 is slidably installed in the groove 24. The plug 25 is slidably connected to the slot 22. The side of the plug 25 facing the groove 24 is connected to the bottom of the groove 24 by a second spring 27. The preload of the second spring 27 causes the plug 25 to move away from the groove 24.

[0045] Specifically, the locking assembly also includes a magnet 28 and an electromagnet 29. One end of the insert 25 passes through the side slider 7. The magnet 28 is fixedly connected to the end of the insert 25 located outside the side slider 7. A second slide groove 402 is provided in the first slide groove 401. The magnet 28 is slidably installed in the second slide groove 402. The electromagnet 29 is fixedly installed in the second slide groove 402. When the two side sliders 7 move away from each other, the magnet 28 on the side slider 7 aligns with the electromagnet 29. At this time, the electromagnet 29 is activated, driving the magnet 28 to move closer to the electromagnet 29, so that the insert 25 moves into the groove 24. At this time, the slider 15 is unlocked from the side slider 7.

[0046] In practical application, before stamping the workpiece, first check whether the insert 25 is inserted into the slot 22 under the preload of the second spring 27 to ensure that the sliding block 15 and the side slider 7 are stably connected. Start the hydraulic rod 3 to drive the moving mold 5 to descend. The inclined guide post 501 is inserted into the inclined guide groove 701 and pushes the side slider 7 along the first slide groove 401 to approach the workpiece. The side slider 7 drives the sliding block 15 to move synchronously through the sliding cooperation of the protrusion 21 and the notch 23. The first inclined edge 16 at the bottom of the sliding block 15 slides in contact with the roller 14, pushing the roller 14 to rotate and causing the fixed plate 12 to drive the top rod 11 to descend until the stamping rod 8 and the side slider 7 complete the stamping of the front and side of the workpiece, respectively.

[0047] When the stamping is completed and the mold is separated, the hydraulic rod 3 drives the moving mold 5 to rise. The side slider 7 moves away from the workpiece under the action of the tension spring 9 and drives the sliding block 15 and the magnet 28 to move. During the movement of the sliding block 15, the first inclined side 16 cooperates with the roller 14, and the preload of the first spring 13 causes the fixed plate 12 to rise, thereby driving the ejector rod 11 to discharge the workpiece. When the magnet 28 is aligned with the electromagnet 29 in the second slide groove 402, the electromagnet 29 is activated. As shown in Figure 8, the electromagnet 29 attracts the magnet 28, causing the magnet 28 to drive the insert block 25 to slide into the groove 24. The sliding block 15 is unlocked from the side slider 7. After unlocking, the movement of the sliding block 15 can be controlled independently, so that the two sliding blocks 15 are brought closer, and the ejector rod 11 retracts into the stamping table 6 to avoid obstructing the placement of the workpiece.

[0048] like Figures 1-8 As shown, in a preferred embodiment of the present invention, a rack plate 17 is slidably installed in the first slide groove 401. The rack plate 17 is fixedly connected to the sliding block 15. A driving component is provided at the bottom of the fixed mold 4. The driving component is connected to the rack plate 17. When the sliding block 15 is unlocked from the side slider 7, the driving component drives the two sliding blocks 15 to move closer to each other. Each of the inserts 25 has a second inclined side 26 at one end. The second inclined side 26 is inclined and the distance between the two second inclined sides 26 increases along the direction close to the top rod 11. The second inclined side 26 slides with the edge of the protrusion 21.

[0049] Specifically, the width of the slot 22 is greater than the width of the insert block 25. When the moving mold 5 and the fixed mold 4 separate, causing the side slider 7 to move away from the workpiece, the insert block 25 and the slot 22 slide together until the side slider 7 is completely away from the workpiece and the insert block 25 abuts against the side wall of the slot 22.

[0050] Specifically, the drive assembly includes a rotating shaft 18, a ratchet assembly 19, and a gear 20. The rotating shaft 18 and the gear 20 are rotatably mounted on the bottom of the fixed mold 4. The rotating shaft 18 is driven to rotate by a drive source. The gear 20 is sleeved on the rotating shaft 18 and is coaxially arranged with the rotating shaft 18. The gear 20 is connected to the rotating shaft 18 through the ratchet assembly 19. The gear 20 meshes with the rack plate 17. When the drive source drives the rotating shaft 18 to rotate, the ratchet assembly 19 is in a locked state. The rotating shaft 18 drives the gear 20 to rotate synchronously through the ratchet assembly 19. The gear 20 drives the rack plate 17 to move toward the ejector rod 11. When the moving mold 5 separates from the fixed mold 4, causing the side slider 7 to move away from the workpiece, the side slider 7 drives the sliding block 15 to move synchronously. The sliding block 15 drives the gear 20 to rotate through the rack plate 17. The ratchet assembly 19 is in a sliding engagement state. At this time, the rotating shaft 18 is stationary.

[0051] In one embodiment, the driving source can be a servo motor, a servo motor or other components, or other mechanisms capable of rotational motion. This embodiment does not impose specific limitations. It should be noted that the ratchet assembly 19 of the present invention includes components such as an internal gear ring, a pawl and a rotating connecting rod. All of the above components are existing technologies, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of the present invention.

[0052] In practical application, this embodiment involves a preparatory operation to retract the push rod 11 into the stamping table 6: such as... Figure 8 Taking the example shown, when the electromagnet 29 is activated, it attracts the magnet 28. Then, the insert block 25 is moved into the groove 24, unlocking the sliding block 15 from the side slider 7. The drive source is then activated, causing the rotating shaft 18 to rotate. At this time, the ratchet assembly 19 is engaged, and the rotating shaft 18 transmits torque to the gear 20 through the ratchet assembly 19. The gear 20 rotates synchronously with the rotating shaft 18. Since the gear 20 meshes with the rack plate 17, the rotation of the gear 20 is converted into the horizontal movement of the rack plate 17 along the first slide groove 401. The rack plate 17 drives the sliding block 15 to move closer to the push rod 11. Figure 4 As shown in the example, when the sliding block 15 approaches the push rod 11, it will squeeze the roller 14 through the first inclined side 16, thereby causing the fixed plate 12 to drive the push rod 11 to descend, so that the push rod 11 retracts into the stamping table 6, and the workpiece can be placed on the stamping table 6.

[0053] During mold closing, this process is as follows: Figures 4 to 1As shown, when the side slider 7 presses against the side of the workpiece, the side slider 7 will gradually move towards the sliding block 15. Then the notch 23 will gradually close with the protrusion 21, and the second inclined edge 26 on the inner insert 25 of the side slider 7 will slide and engage with the edge of the protrusion 21, thereby squeezing and shrinking the insert 25 into the groove 24 until the mold closing is completed. At this time, the side slider 7 has also completed the pressing of the side of the workpiece. At the same time, the groove 24 and the slot 22 are aligned. Then, under the preload of the second spring 27, the insert 25 will engage with the slot 22, thereby establishing a temporary rigid connection between the sliding block 15 and the side slider 7, achieving a locking effect, and preparing for the side slider 7 to drive the sliding block 15 to move during the next mold opening.

[0054] During mold splitting, such as Figure 3 As shown in the example, at this time, the hydraulic rod 3 drives the moving mold 5 to rise, the inclined guide post 501 disengages from the inclined guide groove 701, and the side slider 7 moves away from the workpiece under the preload of the tension spring 9. Since the sliding block 15 and the side slider 7 are locked, the side slider 7 will drive the sliding block 15 to move synchronously along the first slide groove 401 away from the ejector rod 11. During the movement of the sliding block 15, through the cooperation of the first inclined side 16 and the roller 14, the preload of the first spring 13 causes the fixed plate 12 to rise, thereby driving the ejector rod 11 to discharge the workpiece. When the magnet 28 on the side slider 7 is aligned with the electromagnet 29 in the second slide groove 402, the electromagnet 29 activates to attract the magnet 28, causing the insert block 25 to slide into the groove 24. The sliding block 15 and the side slider 7 are unlocked, and then the preparation operation of retracting the ejector rod 11 into the stamping table 6 can be carried out.

[0055] It should be noted that the width of the slot 22 is greater than the width of the insert block 25. When the moving mold 5 and the fixed mold 4 separate, causing the side slider 7 to move away from the workpiece, the insert block 25 and the slot 22 slide together until the side slider 7 is completely away from the workpiece and the insert block 25 abuts against the side wall of the slot 22. This ensures that the sliding block 15 will only move after the side slider 7 is completely separated from the workpiece, and then the ejector rod 11 will lift the workpiece upward to achieve material discharge. This avoids the problem that the ejector rod 11 will push the workpiece upward when the workpiece and the side slider 7 are stuck together.

[0056] Please see Figures 1-8 As shown, the present invention is a sliding block type metal part stamping process. The process is applied to a sliding block type metal part stamping die as described in the above embodiment, and the process includes the following steps:

[0057] Step S1: First, place the workpiece on the stamping table 6;

[0058] Step S2: Then, the hydraulic rod 3 drives the moving mold 5 to descend, so that the stamping rod 8 stamps the stamping table 6. At the same time, the inclined guide post 501 is inserted into the inclined guide groove 701, so that the two side sliders 7 are close to the workpiece, thereby stamping the side of the workpiece.

[0059] Step S3: During mold separation, the moving mold 5 rises and the two side sliders 7 move away from the workpiece through the cooperation of the inclined guide post 501 and the inclined guide groove 701. At the same time, the tension spring 9 will pull the side sliders 7 away from the workpiece.

[0060] Step S4: When the side slider 7 moves away from the workpiece, it will drive the push rod 11 to rise through the linkage component, thereby pushing the stamped workpiece out of the stamping table 6 and realizing automatic material discharge.
