A through hole is provided on one side of the fixing block, and a set of third sliding grooves is provided on the inner wall of the through hole. A third slider is movably connected to the inner wall of the third sliding grooves, and a push block is installed at one end of the third slider. The outer wall of the push block is movably connected to the inner wall of the through hole.

[0013] Preferably, the top of the storage platform is provided with a storage groove, one side of the storage groove is provided with a discharge port, several sets of electromagnets are fitted into the edge of the inner wall of the storage groove, a fixing rod is installed at the bottom of the storage platform, a fixing platform is installed at the bottom of the fixing rod, and several rollers are installed at the bottom of the fixing platform.

[0014] Preferably, a limiting groove is provided on one side of the front and back of the shelf. A pressure spring is movably connected to the inner wall of the limiting groove. One end of the pressure spring is movably connected to a limiting block. The tail end of the outer wall of the limiting block is movably connected to the inner wall of the limiting groove, and the front end of the outer wall of the limiting block is movably connected to the inner wall of the through hole.

[0015] Preferably, a trigger positioning sensor is fitted into the inner wall of the first chute. The trigger positioning sensor is used to detect the trigger block. The outer wall of the trigger block is fitted into the middle of one side of the lower mold. A set of first hydraulic cylinders is fitted into the inner wall of the first chute. A limit rod is installed at the output end of the first hydraulic cylinder. The outer wall of the limit rod is movably connected to a limit hole, and the limit hole is opened at the bottom of the outer wall of the lower mold.

[0016] Preferably, a support platform is installed at the tail end of the top of the forging platform, a top plate is installed on the top of the support platform, a second hydraulic cylinder is fitted into the middle of the top of the top plate, a clamping assembly is installed at the bottom of the second hydraulic cylinder, the clamping assembly is used to clamp the upper mold, and the upper mold is movably connected to the top of the lower mold. A controller is installed on the front of the forging platform, and the controller is used to control the various electrical structures of the forging press.

[0017] Preferably, the clamping assembly includes a clamping plate, the top of which is mounted on the bottom of the second hydraulic cylinder, a laser rangefinder sensor is fitted into the bottom of the clamping plate, the outer wall of the clamping plate is movably connected to the inner wall of the groove, and the groove is located in the middle of the top of the upper mold.

[0018] Preferably, two sets of third hydraulic cylinders are fitted and installed on the outer wall of the clamping plate. The output end of the third hydraulic cylinder is movably connected to the inner wall of the limiting hole, and the limiting hole is opened on the inner wall of the groove.

[0019] Preferably, the operating steps of this quick-change die forging press are as follows:

[0020] S1. The forging press is in standby mode. A spare mold is stored on the platform. The lower mold is movably connected to the second slide groove through the second slider. The second slider is driven by a chain through a rack. The chain is linked by the drive gear, the driven gear, and the transmission belt between the first and second transmission rollers driven by the servo motor.

[0021] S2. When it is necessary to change the mold, the servo motor starts and drives the first transmission roller to rotate through the connecting shaft, which in turn drives the transmission belt and the second transmission roller to rotate. This motion is transmitted to the driving gear on the other side through the meshing of the first transmission gear and the second transmission gear, thereby driving the chain to move along the driving gear and the driven gear in the second slide groove.

[0022] S3. As the chain moves, the rack drives the second slider to slide in the second slide groove, thereby moving the lower mold to the designated position in the first slide groove. At the same time, the trigger positioning sensor on the inner wall of the first slide groove detects the trigger block in the middle of one side of the lower mold, confirming that the mold has reached the predetermined position.

[0023] S4. After the mold is positioned, the first hydraulic cylinder is started, and its output end pushes the limit rod into the limit hole at the bottom of the outer wall of the lower mold to achieve stable positioning of the mold and ensure that the mold will not move during the forging process.

[0024] S5. At this point, the forging press is ready to perform a new forging operation. If it is necessary to replace the current lower die with another die on the platform, simply repeat the above steps, but in the opposite direction. First, move the current die out and send it back to the platform, and at the same time move the new die from the platform to the forging position and fix it.

[0025] Preferably, step S1 further includes the following steps:

[0026] S11. At the same time, the arrangement of the first transmission roller, the second transmission roller, the transmission belt, the first transmission gear, and the second transmission gear enables the servo motor to efficiently drive the two drive gears to rotate in opposite directions.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention effectively constrains the movement trajectory of the lower die by setting up a forging platform, a first slide groove, and a second slide groove, ensuring the accuracy of its movement. At the same time, the arrangement of the first transmission roller, the second transmission roller, the transmission belt, the first transmission gear, and the second transmission gear enables the servo motor to efficiently drive the two drive gears to rotate in opposite directions. Furthermore, through the structure of the second slider and rack at the bottom of the lower die, the rotation of the drive gear can smoothly drive the chain to move, realizing the smooth sliding of the lower die in the first slide groove, thereby improving the production efficiency of the forging press and enhancing its operational flexibility.

[0029] 2. This invention features a third sliding groove designed within a through hole on the fixed block, into which a third slider is movably embedded. A push block connected to one end of the third slider can move flexibly within the through hole. The platform is equipped with a storage slot and a discharge port. An electromagnet is embedded in the edge of the storage slot to facilitate the stable placement and rapid release of the mold. The bottom of the platform is connected to the fixed platform via a fixed rod. Rollers are installed under the fixed platform to facilitate overall movement. In addition, limiting slots are provided on the front and rear sides of the platform, with built-in pressure springs and limiting blocks. Through the elastic force of the pressure springs, the limiting blocks can fit tightly against the inner wall of the through hole, ensuring a stable connection between the platform and the forging platform. At the same time, the push block can be pressed to quickly separate the platform, improving the convenience of mold replacement and the overall flexibility and production efficiency of the forging press.

[0030] 3. The present invention uses a trigger positioning sensor that is fitted together to accurately detect the trigger block fitted in the middle of one side of the lower mold, ensuring accurate identification of the mold position. At the same time, a set of first hydraulic cylinders is also fitted together in the first slide groove. The output end of the first hydraulic cylinder is connected to a limit rod, which can be flexibly inserted into the limit hole opened at the bottom of the lower mold to achieve stable mold positioning. This design not only improves the accuracy and stability of mold positioning, but also further enhances the intelligence level and production efficiency of the forging press through automated sensing and hydraulic control.

[0031] 4. This invention, through its clamping assembly, facilitates precise engagement between the upper and lower molds. The clamping plate, as a core component, has a laser rangefinder embedded in its bottom, enabling accurate measurement of the distance to the top of the upper mold for precise positioning. The outer wall of the clamping plate is movably connected to a groove on the top of the upper mold, enhancing clamping stability. Furthermore, two sets of third hydraulic cylinders are embedded in the outer wall of the clamping plate, their output ends movably connected to limiting holes in the inner wall of the groove, further reinforcing the clamping effect. The controller on the front of the forging platform controls the electrical structure of the entire forging press, ensuring coordinated operation of all components and improving the automation and processing accuracy of the forging process.

Thus, through the structure of the second slider 15 and the rack 14 at the bottom of the lower die 16, the rotation of the drive gear 5 can smoothly drive the chain 6 to move, achieving smooth sliding of the lower die 16 within the first slide 2. This improves the production efficiency of the forging press and enhances its operational flexibility.

This design not only improves the accuracy and stability of mold positioning, but also further enhances the intelligence level and production efficiency of the forging press through automated sensing and hydraulic control.

[0054] Example 4: Please refer to Figure 1 and Figure 6 An embodiment of the present invention is provided: a support platform 36 is installed at the tail end of the top of the forging platform 1, a top plate 37 is installed on the top of the support platform 36, a second hydraulic cylinder 38 is fitted in the middle of the top of the top of the top plate 37, a clamping assembly is installed at the bottom of the second hydraulic cylinder 38, the clamping assembly is used to clamp the upper mold 39, and the upper mold 39 is movably connected to the top of the lower mold 16. A controller 45 is installed on the front of the forging platform 1, and the controller 45 is used to control the electrical structure of the forging press.

[0055] The clamping assembly includes a clamping plate 40, and the top of the clamping plate 40 is mounted on the bottom of the second hydraulic cylinder 38.

[0056] Two sets of third hydraulic cylinders 43 are fitted and installed on the outer wall of the clamping plate 40. The output end of the third hydraulic cylinder 43 is movably connected to the inner wall of the limiting hole 44, and the limiting hole 44 is opened on the inner wall of the groove 42.

[0057] Furthermore, the clamping assembly helps ensure that the upper mold 39 can accurately cooperate with the lower mold 16. As a core component, the clamping plate 40 has a laser range sensor 41 installed at its bottom that can accurately measure the distance to the top of the upper mold 39, achieving precise positioning. The outer wall of the clamping plate 40 is movably connected to the groove 42 opened on the top of the upper mold 39, enhancing the stability of the clamping. In addition, two sets of third hydraulic cylinders 43 are also embedded in the outer wall of the clamping plate 40, and their output ends are movably connected to the limiting holes 44 in the inner wall of the groove 42, further strengthening the clamping effect. The controller 45 on the front of the forging platform 1 is responsible for controlling the electrical structure of the entire forging press, ensuring that all components work together, and improving the automation level and processing accuracy of the forging operation.

[0058] Example 5: Please refer to Figure 8 The present invention provides an embodiment of the forging press with quick die change as follows:

[0059] S1. The forging press is in standby mode. The stand 3 contains a spare mold. The lower mold 16 is movably connected to the second slide 4 through the second slider 15. The second slider 15 is driven by the chain 6 through the rack 14. The chain 6 is linked by the transmission belt 10 between the first transmission roller 8 and the second transmission roller 11 driven by the drive gear 5, the driven gear 7, and the servo motor 9.

[0060] S2. When it is necessary to change the mold, the servo motor 9 starts and drives the first transmission roller 8 to rotate through the connecting shaft, which in turn drives the transmission belt 10 and the second transmission roller 11 to rotate. This motion is transmitted to the driving gear 5 on the other side through the meshing of the first transmission gear 12 and the second transmission gear 13, thereby driving the chain 6 to move along the driving gear 5 and the driven gear 7 in the second slide groove 4.

[0061] S3. As the chain 6 moves, the rack 14 drives the second slider 15 to slide in the second slide groove 4, thereby driving the lower mold 16 to move to the designated position in the first slide groove 2. At the same time, the trigger positioning sensor 31 on the inner wall of the first slide groove 2 detects the trigger block 32 in the middle of one side of the lower mold 16, confirming that the mold has reached the predetermined position.

[0062] S4. After the mold is positioned, the first hydraulic cylinder 33 is started, and its output end pushes the limit rod 34 into the limit hole 35 at the bottom of the outer wall of the lower mold 16 to achieve stable positioning of the mold and ensure that the mold will not move during the forging process.

[0063] S5. At this time, the forging press is ready to carry out a new forging operation. If it is necessary to replace the current lower die 16 with another die on the platform 3, simply repeat the above steps, but in the opposite direction. First, move the current die out and send it back to the platform 3, and at the same time move the new die from the platform 3 to the forging position and fix it.

[0064] S6. While the lower mold 16 moves, the platform 3 can be easily moved to the appropriate position by the roller 27 and the fixed rod 25 so as to take out or put in the mold. The electromagnet 24 is turned off by the controller 45 to release the mold in the storage slot 22. The mold can be pushed out from the discharge port 23 by the sliding of the push block 21 and the third slider 20 in the third slide groove 19.

[0065] S7. The controller 45 starts the second hydraulic cylinder 38, which drives the clamping plate 40 to move downward until the laser range sensor 41 detects an appropriate distance from the top of the upper mold 39. The controller 45 adjusts the position of the clamping plate 40 according to the feedback from the laser range sensor 41, and then starts the third hydraulic cylinder 43 to fix the clamping plate 40 in the groove 42 on the top of the upper mold 39.

[0066] S1 also includes the following steps:

[0067] S11. At the same time, the arrangement of the first transmission roller 8, the second transmission roller 11, the transmission belt 10, the first transmission gear 12 and the second transmission gear 13 enables the servo motor 9 to efficiently drive the two drive gears 5 to rotate in opposite directions.

[0068] The working principle is as follows: the forging platform 1, the first slide 2, and the second slide 4 effectively constrain the movement trajectory of the lower die 16, ensuring its movement accuracy. Simultaneously, the arrangement of the first transmission roller 8, the second transmission roller 11, the transmission belt 10, the first transmission gear 12, and the second transmission gear 13 enables the servo motor 9 to efficiently drive the two drive gears 5 to rotate in opposite directions. Furthermore, through the structure of the second slider 15 and rack 14 at the bottom of the lower die 16, the rotation of the drive gears 5 smoothly drives the chain 6, achieving stable sliding of the lower die 16 within the first slide 2. This improves the production efficiency of the forging press and enhances its operational flexibility. The fixed block 17 has openings for... A third slide groove 19 is designed inside the hole 18, and a third slider 20 is movably embedded in the third slide groove 19. The push block 21 connected to one end of the third slider 20 can move flexibly within the through hole 18. The platform 3 is provided with a storage slot 22 and a discharge port 23. An electromagnet 24 is embedded in the edge of the storage slot 22 to facilitate the stable placement and rapid release of the mold. The bottom of the platform 3 is connected to the fixed platform 26 via a fixing rod 25. The fixed platform 26 is equipped with rollers 27 to facilitate overall movement. In addition, the front and rear sides of the platform 3 are provided with limiting slots 28, which contain pressure springs 29 and limiting blocks 30. Through the elastic force of the pressure springs 29, the limiting blocks 30 can fit tightly against the inner wall of the through hole 18 to ensure a stable connection between the platform 3 and the forging platform 1. The pressing push block 21 enables rapid separation, improving the convenience of mold replacement and the overall flexibility and production efficiency of the forging press. A trigger positioning sensor 31, installed in a fitted configuration, accurately detects the trigger block 32 fitted into the center of one side of the lower mold 16, ensuring precise mold position identification. Simultaneously, a set of first hydraulic cylinders 33 is fitted into the first slide groove 2. The output end of the first hydraulic cylinder 33 is connected to a limit rod 34, which can flexibly insert into the limit hole 35 at the bottom of the lower mold 16, achieving stable mold positioning. This design not only improves the accuracy and stability of mold positioning but also further enhances the intelligence level and production efficiency of the forging press through automated sensing and hydraulic control. Efficiency is improved through the clamping assembly, which helps ensure that the upper mold 39 can accurately fit with the lower mold 16. The clamping plate 40, as the core component, has a laser range sensor 41 installed at its bottom that can accurately measure the distance to the top of the upper mold 39, achieving precise positioning. The outer wall of the clamping plate 40 is movably connected to the groove 42 opened on the top of the upper mold 39, which enhances the stability of clamping. In addition, two sets of third hydraulic cylinders 43 are also embedded in the outer wall of the clamping plate 40, and their output ends are movably connected to the limiting holes 44 in the inner wall of the groove 42, which further strengthens the clamping effect. The controller 45 on the front of the forging platform 1 is responsible for controlling the electrical structure of the entire forging press, ensuring that all components work together, and improving the automation level and processing accuracy of the forging operation.
