Description

Technical Field

[0001] This invention belongs to the field of forging and powder metallurgy product manufacturing technology, specifically a forging press for metal product processing. Background Technology

[0002] The metal products industry encompasses the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and everyday metal products, and more. With societal development, the applications of metal products are becoming increasingly widespread. Forging (including forging and stamping) is a processing method that uses equipment or dies to apply pressure to a blank, causing it to plastically deform to obtain the desired shape and size. Metal products are generally formed through forging.

[0003] A patent with publication number CN119857809A discloses an injection mold, including a support foot, a worktable fixedly connected to the top of the support foot, a support column fixedly connected to the top of the worktable, and a cooling box fixedly connected to the top of the support column. The cooling box is equipped with a forging mechanism and a deformation mechanism, and a heat dissipation mechanism is provided on the back of the cooling box. When forging is required, the forging part is placed on the top of the worktable, and then the hydraulic lifting rod is opened. When the hydraulic lifting rod is working, it controls the connecting rod to move down, so that the pressure plate at the bottom of the connecting rod moves down, so that the pressure plate contacts and squeezes the forging part when it moves down, thereby completing the forging work.

[0004] When using existing forging presses to make metal products, after the forging work is completed, the metal products need to be demolded. Currently, the demolding work is mainly done by workers holding clamps to lift one side of the metal product and remove it. This is not only labor-intensive, but also makes it difficult to ensure that the force and angle of demolding are consistent each time, which can easily lead to deformation or damage of the metal products and affect product quality.

[0005] In addition, after each forging is completed, a release agent needs to be manually sprayed onto the top pressure plate and the bottom mold plate. This process is also labor-intensive, and it is difficult to accurately control the uniformity of the spray. Uneven spraying of the release agent will make it difficult to demold the subsequent metal products, and may even cause the mold to stick, further damaging the products.

[0006] Therefore, the present invention provides a forging press for processing metal products. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a forging press for metal product processing, including a machine body, a top plate fixedly connected to the top of the machine body, a first hydraulic cylinder fixedly connected to the upper surface of the top plate, a pressure plate provided at the output end of the first hydraulic cylinder, a fixed plate fixedly connected to the middle of the machine body, a guide plate fixedly connected to the upper surface of the fixed plate, a mold plate provided on the upper surface of the fixed plate, two sets of mold plates rotatably disposed on the upper surface of the fixed plate, and the two sets of mold plates and the pressure plate are used for forging work;

[0009] One of the mold plates has a lifting assembly on its upper surface. The lifting assembly includes an electric push rod fixed to the upper surface of the mold plate. The output end of the electric push rod is fixed to a positioning frame. A sliding plate is slidably connected to one side of the positioning frame. The cross-section of the sliding plate is triangular.

[0010] Two sets of spraying components are symmetrically arranged on the upper surface of the fixed plate. Each spraying component includes a support plate fixed to one side of the fixed plate. A second hydraulic cylinder is fixed to the upper surface of the support plate. A fixed housing is fixed to the output end of the second hydraulic cylinder. A spray pipe is fixed to the side of the fixed housing near the mold plate. The spray pipe is a "Y" shaped spray pipe.

[0011] Preferably, the lifting assembly includes a positioning groove formed on one side of the positioning frame, a plurality of positioning springs are fixedly connected to the top wall of the positioning groove, the top of the plurality of positioning springs are fixedly connected to the same positioning plate, the positioning plate is fixedly connected to the sliding plate, a limit groove is formed on the upper surface of the positioning frame, an auxiliary plate is rotatably arranged within the limit groove, and the positioning plate slides down to trigger the auxiliary plate to rotate, thereby supporting the finished metal product.

[0012] Preferably, the positioning plate has several gears rotatably connected inside, and several rack plates that mesh with the gears are fixed to the side wall of the positioning groove. The positioning plate also has a transmission belt connected inside, and the transmission belt and the gears share the same transmission shaft. The gears are fixed to the transmission shaft. The top of the positioning frame is rotatably connected to a positioning shaft. Two protrusions are fixed to the circumferential surface of the positioning shaft. The two protrusions are fixed to an auxiliary plate. The positioning shaft is connected to the transmission belt.

[0013] Preferably, the metal plate to be forged is first placed on the upper surface of two spliced ​​mold plates. The first hydraulic cylinder is started to drive the pressure plate at the output end of the first hydraulic cylinder to cooperate with the mold plate to forge the metal plate. After forging is completed, the electric push rod of the lifting component is started. The electric push rod pushes the positioning frame at its output end. The positioning frame then pushes the sliding plate on one side of it closer to the formed metal product. The sliding plate is inserted along one side of the metal product and lifts the metal product.

[0014] Preferably, after the sliding plate lifts the metal product, it is fully inserted under the metal product and moves into the mold plate groove. Under the elastic force of the positioning spring, the sliding plate slides downward, triggering the rotation of the auxiliary plate. The rotation of the auxiliary plate lifts the metal product a second time, assisting the metal product to detach from one of the metal mold plates.

[0015] Preferably, as the slide plate slides downwards along the mold plate groove, the gear inside the positioning plate rotates along the rack plate fixed to the inner wall of the positioning groove. The rotation of the gear drives the transmission shaft in the middle, and the rotation of the transmission shaft drives the transmission belt to drive the transmission, which in turn drives the positioning shaft connected to the transmission belt to rotate. The rotation of the positioning shaft drives the two protrusions fixed to its circumference, which in turn drives the auxiliary plate fixed to the two protrusions, causing the auxiliary plate to disengage from the limiting groove, completing the secondary demolding of the metal product. After the demolding work is completed, the mold plate away from the lifting component is driven to rotate. The mold plate will then carry the metal product to the guide plate, and the metal product will fall onto the guide plate for unloading. After completion, the mold plate rotates and resets.

[0016] Preferably, the spraying assembly further includes trigger rods fixed to both sides of the positioning frame, a fixing groove is provided inside the fixing box, a rotating rod is rotatably connected inside the fixing groove, a compression spring is fixed to the inner wall of the fixing groove, a sealing plate is fixed to one end of the compression spring, a number of fixing holes are provided on the surface of the sealing plate, and a number of auxiliary holes are provided inside the fixing box.

[0017] Preferably, after the forging and blanking operations are completed and the mold plate automatically resets, the second hydraulic cylinder on the upper surface of the support plate is activated. After the second hydraulic cylinder is activated, it drives the fixed box to approach the groove of the mold plate. Then, the electric push rod is activated to push the trigger rods on both sides of the positioning frame. The trigger rods push the rotating rod to rotate elastically, squeezing the sealing plate into the fixed groove and squeezing the compression spring on the inner wall of the fixed groove. At this time, the fixed hole and the auxiliary hole are aligned. The built-in pressure pump of the fixed box squeezes the release agent out of the spray pipe. The spray pipe simultaneously sprays the release agent onto the pressure plate and the mold plate.

[0018] Preferably, a rotating shaft is fixed to the bottom wall of the fixing groove, the rotating rod rotates around the rotating shaft, a fixing frame is fixed to one end of the rotating rod, an auxiliary rod is fixed inside the fixing frame, a connecting rod is sleeved on the circumferential surface of the auxiliary rod, an auxiliary groove is opened inside the connecting rod, the auxiliary rod is located in the connecting groove, a connecting spring is sleeved on the circumferential surface of the connecting rod, a tapered rod is fixed to one end of the connecting rod, and an arc-shaped block is fixed to the inner wall of the fixing frame.

[0019] Preferably, when the trigger rod pushes the rotating rod to rotate, the rotating rod rotates around the rotating axis. At the same time, the auxiliary rod inside the fixed frame slides along the auxiliary groove to compress the connecting spring. Then, the tapered rod slides along the arc block to the other side. The rotation of the rotating rod drives the fixed frame to push the sealing plate into the fixed groove, so that the fixing hole on the surface of the sealing plate is aligned with the auxiliary hole inside the fixed box, thereby connecting the spray pipe and the fixed box. At this time, the pressure pump inside the fixed box can squeeze the release agent out of the spray pipe. The rotating rod is triggered by the trigger rod during the first retraction of the electric push rod. After the spraying work is completed, when the electric push rod is started again to trigger the trigger rod, the trigger rod resets the rotating rod during the pushing process. Then, the second hydraulic cylinder drives the fixed box away from the mold plate. At this time, the trigger rod cannot touch the rotating rod during the retraction process, thus completing the spraying work.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The forging press for metal product processing described in this invention, through the design of two sets of rotatable mold plates, can adapt to the forging requirements of metal plates of different sizes, improving the versatility of the equipment; the lifting component achieves smooth demolding through a sliding plate triangular structure, avoiding deformation or damage to metal products and improving the yield; the spraying component adopts a "Y"-shaped spray nozzle to expand the spraying range, spraying the pressure plate and mold plate simultaneously and ensuring uniform coverage, effectively reducing mold wear and extending service life; through the coordinated control of hydraulic cylinders and electric push rods, the entire process of forging, demolding, and spraying is automated, reducing manual intervention, ensuring operational safety, and is suitable for large-scale metal product processing scenarios.

[0022] 2. The forging press for metal product processing described in this invention first inserts a sliding plate in the lifting assembly to lift the metal product, and then lifts it a second time with the help of a positioning spring and an auxiliary plate. This ensures that the metal product is completely removed from the mold, avoids adhesion damage, and improves the quality of the finished product. When the sliding plate slides, the auxiliary plate is driven to move precisely through a linkage structure such as gears and racks. The automation level is high, reducing manual intervention. After demolding, the mold plate automatically rotates to send the product to the guide plate for unloading. This realizes a continuous operation of the entire process of forging, demolding, and unloading, improving production efficiency. The overall structure is compact and reasonable, and the components work together to ensure the stability and efficiency of processing and reduce production costs.

[0023] 3. The forging press for metal product processing described in this invention, after forging and blanking, drives the fixed box to approach the mold plate groove, positioning the spraying area and preparing for subsequent operations. An electric push rod is activated to push the trigger rod. After the trigger rod moves past the rotating rod, it retracts during the recovery process, causing the rotating rod to rotate elastically and the sealing plate to retract into the fixed groove, aligning the fixed hole with the auxiliary hole. This allows the spray nozzle to connect to the fixed box, ensuring the release agent can be sprayed smoothly. The spray nozzle can simultaneously spray the pressure plate and mold plate, greatly improving work efficiency and ensuring uniform spraying of the release agent. This effectively reduces wear on the mold and pressure plate, extends their service life, reduces production costs, and ensures the quality and stability of subsequent forging operations.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] Example 1: As Figures 1 to 9 As shown in the embodiment of the present invention, a forging press for processing metal products includes a machine body 1. A top plate 11 is fixedly connected to the top of the machine body 1. A first hydraulic cylinder 12 is fixedly connected to the upper surface of the top plate 11. A pressure plate is provided at the output end of the first hydraulic cylinder 12. A fixing plate 13 is fixedly connected to the middle of the machine body 1. A guide plate 14 is fixedly connected to the upper surface of the fixing plate 13. A mold plate 15 is provided on the upper surface of the fixing plate 13. Two sets of mold plates 15 are rotatably disposed on the upper surface of the fixing plate 13, and the two sets of mold plates 15 and the pressure plate are used for forging operations.

[0040] One of the mold plates 15 has a lifting assembly on its upper surface. The lifting assembly includes an electric push rod 3 fixed to the upper surface of the mold plate 15. The output end of the electric push rod 3 is fixed to a positioning frame 32. A sliding plate 31 is slidably connected to one side of the positioning frame 32. The cross section of the sliding plate 31 is triangular.

[0041] Two sets of spraying components are symmetrically arranged on the upper surface of the fixed plate 13. The spraying components include a support plate 2 fixed to one side of the fixed plate 13, a second hydraulic cylinder 21 fixed to the upper surface of the support plate 2, a fixed housing 22 fixed to the output end of the second hydraulic cylinder 21, and a spray pipe 23 fixed to the side of the fixed housing 22 near the mold plate 15. The spray pipe 23 is a "Y" shaped spray pipe 23.

[0042] Specifically, when using existing forging presses to make metal products, after the forging work is completed, the metal products need to be demolded. Currently, the demolding work is mainly done by workers holding clamps to lift one side of the metal product and remove it. This is not only labor-intensive, but also makes it difficult to ensure that the force and angle of demolding are consistent each time, which can easily lead to deformation or damage of the metal products and affect product quality.

[0043] In addition, after each forging is completed, the top pressure plate and bottom mold plate 15 need to be manually sprayed with release agent. This process is also labor-intensive, and the uniformity of the spray is difficult to control precisely. Uneven spraying of release agent will make it difficult to demold the subsequent metal products, and may even cause the mold to stick, further damaging the product.

[0044] Therefore, this invention solves the above problems by setting up the above structure. First, during processing, the metal plate to be processed is placed between two sets of mold plates 15. The first hydraulic cylinder 12 drives the pressure plate to press down, cooperating with the mold plate 15 to complete the forging operation. After forging is completed, the electric push rod 3 in the lifting assembly pushes the positioning frame 32 to move. The positioning frame 32 drives the sliding plate 31 (with a triangular cross-section) to smoothly push the forged metal product out of the mold, making it easy to remove the part. After the forging is completed, the two sets of spraying components symmetrically arranged on the fixed plate 13 are activated. The second hydraulic cylinder 21 pushes the fixed box 22 close to the mold plate 15, and sprays the release agent evenly onto the mold plate 15 and the surface of the pressure plate through the "Y"-shaped spray pipe 23 to prepare for the next forging.

[0045] The design of two sets of rotatable mold plates 15 can adapt to the forging requirements of metal plates of different sizes, improving the versatility of the equipment; the lifting component achieves smooth demolding through the triangular structure of the sliding plate 31, avoiding deformation or damage to metal products and improving the yield; the spraying component adopts a "Y"-shaped spray nozzle 23 to expand the spraying range, spray the pressure plate and mold plate 15 simultaneously, and ensure uniform coverage, effectively reducing mold wear and extending service life; through the coordinated control of hydraulic cylinder and electric push rod 3, the entire process of forging, demolding and spraying is automated, reducing manual intervention, ensuring operational safety, and is suitable for large-scale metal product processing scenarios.

[0046] like Figure 4 and Figure 5 As shown, the lifting assembly in this embodiment includes a positioning groove 33 on one side of the positioning frame 32. Several positioning springs 34 are fixed to the top wall of the positioning groove 33. The top of the several positioning springs 34 is fixed to the same positioning plate 35. The positioning plate 35 is fixed to the slide plate 31. A limit groove 310 is provided on the upper surface of the positioning frame 32. An auxiliary plate 39 is rotatably arranged within the limit groove. The positioning plate 35 slides down to trigger the auxiliary plate 39 to rotate, thereby supporting the finished metal product.

[0047] The positioning plate 35 has several gears 36 rotatably connected inside. The side wall of the positioning groove 33 has several rack plates 37 that mesh with the gears 36. The positioning plate 35 also has a transmission belt 311 rotatably connected inside. The transmission belt 311 and the gears 36 are on the same transmission shaft. The gears 36 are fixed to the transmission shaft. The top of the positioning frame 32 has a positioning shaft 38 rotatably connected. Two protrusions 312 are fixed to the circumference of the positioning shaft 38. The two protrusions 312 are fixed to the auxiliary plate 39. The positioning shaft 38 is rotatably connected to the transmission belt 311.

[0048] Specifically, the metal plate to be forged is first placed on the upper surface of two spliced ​​mold plates 15. The first hydraulic cylinder 12 is started to drive the pressure plate at the output end of the first hydraulic cylinder 12 to cooperate with the mold plate 15 to forge the metal plate. After forging is completed, the electric push rod 3 of the lifting component is started. The electric push rod 3 pushes the positioning frame 32 at its output end. The positioning frame 32 then pushes the sliding plate 31 on one side of it closer to the formed metal product. The sliding plate 31 is inserted along one side of the metal product to lift the metal product.

[0049] After the slide plate 31 lifts the metal product, it is fully inserted under the metal product. After moving into the groove of the mold plate 15, the slide plate 31 slides down under the elastic force of the positioning spring 34, and at the same time triggers the rotation of the auxiliary plate 39. The rotation of the auxiliary plate 39 lifts the metal product a second time, assisting the metal product to detach from one of the metal mold plates 15.

[0050] Additionally, as the slide plate 31 slides downward along the groove of the mold plate 15, the gear 36 inside the positioning plate 35 will rotate along the rack plate 37 fixed to the inner wall of the positioning groove 33. The rotation of the gear 36 drives the transmission shaft in the middle, and the rotation of the transmission shaft drives the transmission belt 311 to drive, which in turn drives the positioning shaft 38 connected to the transmission belt 311 to rotate. The rotation of the positioning shaft 38 drives the two protrusions 312 fixed to its circumference, which in turn drives the auxiliary plate 39 fixed to the two protrusions 312, causing the auxiliary plate 39 to disengage from the limiting groove 310, completing the secondary demolding of the metal product. After the demolding work is completed, the mold plate 15 away from the lifting component is driven to rotate. The mold plate 15 will rotate with the metal product to the guide plate 14, and then the metal product falls onto the guide plate 14 for unloading. After completion, the mold plate 15 rotates to reset.

[0051] In the lifting assembly, the slide plate 31 first inserts to lift the metal product, and then lifts it a second time with the help of the positioning spring 34 and the auxiliary plate 39, ensuring that the metal product is completely removed from the mold, avoiding adhesion and damage, and improving the quality of the finished product. When the slide plate 31 slides, the auxiliary plate 39 is driven to move precisely through the linkage structure such as the gear 36 and the rack plate 37. The automation level is high and manual intervention is reduced. After demolding, the mold plate 15 automatically rotates to send the product to the guide plate 14 for unloading, realizing the continuous operation of the entire process of forging, demolding and unloading, improving production efficiency. The overall structure is compact and reasonable, and the components work together to ensure the stability and efficiency of processing and reduce production costs.

[0052] Example 2: Figures 1 to 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the spraying assembly further includes trigger rods 4 fixed to both sides of the positioning frame 32, a fixing groove 24 is provided inside the fixing box 22, a rotating rod 25 is rotatably connected inside the fixing groove 24, a compression spring 213 is fixed to the inner wall of the fixing groove 24, a sealing plate 214 is fixed to one end of the compression spring 213, a plurality of fixing holes 215 are provided on the surface of the sealing plate 214, and a plurality of auxiliary holes 216 are provided inside the fixing box 22.

[0053] Specifically, after the forging and blanking operations are completed, the mold plate 15 automatically resets, and the second hydraulic cylinder 21 on the upper surface of the support plate 2 is activated. After the second hydraulic cylinder 21 is activated, it will drive the fixed box 22 to approach the groove of the mold plate 15. Then, the electric push rod 3 is activated to push the trigger rods 4 on both sides of the positioning frame 32. The trigger rods 4 push the rotating rod 25 to rotate elastically, squeezing the sealing plate 214 into the fixed groove 24 and squeezing the compression spring 213 on the inner wall of the fixed groove 24. At this time, the fixed hole 215 is aligned with the auxiliary hole 216. The built-in pressure pump of the fixed box 22 squeezes the release agent out of the spray pipe 23. The spray pipe 23 simultaneously sprays the release agent onto the pressure plate and the mold plate 15.

[0054] After forging and blanking are completed, the second hydraulic cylinder 21 drives the fixed box 22 to approach the mold plate 15 groove, positioning the spraying area and preparing for subsequent operations. The electric push rod 3 is activated to push the trigger rod 4. After the trigger rod 4 moves past the rotating rod 25, the rotating rod 25 rotates elastically during the retraction process, and the sealing plate 214 retracts into the fixed groove 24, aligning the fixed hole 215 with the auxiliary hole 216. This allows the spray pipe 23 to connect to the fixed box 22, ensuring that the release agent can be sprayed out smoothly. The spray pipe 23 can spray the pressure plate and the mold plate 15 simultaneously, which greatly improves work efficiency, ensures uniform spraying of the release agent, effectively reduces wear on the mold and pressure plate, extends their service life, reduces production costs, and ensures the quality and stability of subsequent forging operations.

[0055] like Figures 7 to 9As shown, in this embodiment, a rotating shaft 26 is fixedly connected to the bottom wall of the fixing groove 24, and a rotating rod 25 rotates around the rotating shaft 26. A fixing frame 27 is fixedly connected to one end of the rotating rod 25. An auxiliary rod 28 is fixedly connected inside the fixing frame 27. A connecting rod 29 is sleeved on the circumferential surface of the auxiliary rod 28. An auxiliary groove 217 is opened inside the connecting rod 29. The auxiliary rod 28 is located in the connecting groove. A connecting spring 210 is sleeved on the circumferential surface of the connecting rod 29. A tapered rod 211 is fixedly connected to one end of the connecting rod 29. An arc-shaped block 212 is fixedly connected to the inner wall of the fixing frame 27.

[0056] Specifically, when the trigger rod 4 pushes the rotating rod 25 to rotate, the rotating rod 25 rotates around the rotating shaft 26. At the same time, the auxiliary rod 28 inside the fixed frame 27 slides along the auxiliary groove 217 to compress the connecting spring 210. Then, the tapered rod 211 slides along the arc block 212 to the other side. The rotation of the rotating rod 25 drives the fixed frame 27 to push the sealing plate 214 into the fixed groove 24, so that the fixing hole 215 on the surface of the sealing plate 214 is aligned with the auxiliary hole 216 inside the fixed box 22, thereby connecting the nozzle. 23 and fixed box 22, at this time the pressure pump in fixed box 22 can squeeze the release agent to be sprayed out from spray nozzle 23. Rotating rod 25 is triggered by trigger rod 4 during the first retraction of electric push rod 3. After the spraying work is completed, when electric push rod 3 is started again to drive trigger rod 4, trigger rod 4 resets rotating rod 25 during the pushing process. Then the second hydraulic cylinder 21 drives fixed box 22 away from mold plate 15, and at this time the trigger rod 4 cannot touch rotating rod 25 during the retraction process, thus completing the spraying work.

[0057] The automatic triggering effect is achieved, so that the spraying component does not affect the forging and lifting components during normal forging operations. After forging is completed, the mold plate 15 and the pressure plate are sprayed with release agent, which improves the forging efficiency.

[0058] Working principle: When using the forging press, the metal plate to be forged is first placed on the upper surface of two spliced ​​mold plates 15. The first hydraulic cylinder 12 is started to drive the pressure plate at the output end of the first hydraulic cylinder 12 to cooperate with the mold plate 15 to forge the metal plate. After forging is completed, the electric push rod 3 of the lifting component is started. The electric push rod 3 pushes the positioning frame 32 at its output end. The positioning frame 32 then pushes the sliding plate 31 on one side of it closer to the formed metal product. The sliding plate 31 is inserted along one side of the metal product to lift the metal product.

[0059] After the slide plate 31 lifts the metal product, it is fully inserted under the metal product. After moving into the groove of the mold plate 15, the slide plate 31 slides down under the elastic force of the positioning spring 34, and at the same time triggers the rotation of the auxiliary plate 39. The rotation of the auxiliary plate 39 lifts the metal product a second time, assisting the metal product to detach from one of the metal mold plates 15.

[0060] Additionally, as the slide plate 31 slides downward along the groove of the mold plate 15, the gear 36 inside the positioning plate 35 will rotate along the rack plate 37 fixed to the inner wall of the positioning groove 33. The rotation of the gear 36 drives the transmission shaft in the middle, and the rotation of the transmission shaft drives the transmission belt 311 to drive, which in turn drives the positioning shaft 38 connected to the transmission belt 311 to rotate. The rotation of the positioning shaft 38 drives the two protrusions 312 fixed to its circumference, which in turn drives the auxiliary plate 39 fixed to the two protrusions 312, causing the auxiliary plate 39 to disengage from the limiting groove 310, completing the secondary demolding of the metal product. After the demolding work is completed, the mold plate 15 away from the lifting component is driven to rotate. The mold plate 15 will rotate with the metal product to the guide plate 14, and then the metal product falls onto the guide plate 14 for unloading. After completion, the mold plate 15 rotates to reset.

[0061] In the lifting assembly, the slide plate 31 first inserts to lift the metal product, and then lifts it a second time with the help of the positioning spring 34 and the auxiliary plate 39, ensuring that the metal product is completely removed from the mold, avoiding adhesion and damage, and improving the quality of the finished product. When the slide plate 31 slides, the auxiliary plate 39 is driven to move precisely through the linkage structure such as the gear 36 and the rack plate 37. The automation level is high and the manual intervention is reduced. After demolding, the mold plate 15 automatically rotates to send the product to the guide plate 14 for unloading, realizing the continuous operation of the entire process of forging, demolding and unloading, improving production efficiency. The overall structure is compact and reasonable, and the components work together to ensure the stability and efficiency of processing and reduce production costs.

[0062] After the forging and blanking operations are completed, the mold plate 15 automatically resets and the second hydraulic cylinder 21 on the upper surface of the support plate 2 is activated. After the second hydraulic cylinder 21 is activated, it will drive the fixed box 22 to approach the groove of the mold plate 15. Then, the electric push rod 3 is activated to push the trigger rods 4 on both sides of the positioning frame 32. The trigger rods 4 push the rotating rod 25 to rotate elastically, squeezing the sealing plate 214 into the fixed groove 24 and squeezing the compression spring 213 on the inner wall of the fixed groove 24. At this time, the fixed hole 215 is aligned with the auxiliary hole 216. The built-in pressure pump of the fixed box 22 squeezes the release agent out of the spray pipe 23. The spray pipe 23 simultaneously sprays the release agent onto the pressure plate and the mold plate 15.

[0063] When the trigger rod 4 pushes the rotating rod 25 to rotate, the rotating rod 25 rotates around the rotating shaft 26. At the same time, the auxiliary rod 28 inside the fixed frame 27 slides along the auxiliary groove 217 to compress the connecting spring 210. Then, the tapered rod 211 slides along the arc block 212 to the other side. The rotation of the rotating rod 25 drives the fixed frame 27 to push the sealing plate 214 into the fixed groove 24, so that the fixing hole 215 on the surface of the sealing plate 214 is aligned with the auxiliary hole 216 inside the fixed box 22, thereby connecting the nozzle. 23 and fixed box 22, at this time the pressure pump in fixed box 22 can squeeze the release agent to be sprayed out from spray nozzle 23. Rotating rod 25 is triggered by trigger rod 4 during the first retraction of electric push rod 3. After the spraying work is completed, when electric push rod 3 is started again to drive trigger rod 4, trigger rod 4 resets rotating rod 25 during the pushing process. Then the second hydraulic cylinder 21 drives fixed box 22 away from mold plate 15, and at this time the trigger rod 4 cannot touch rotating rod 25 during the retraction process, thus completing the spraying work.

[0064] After forging and blanking are completed, the second hydraulic cylinder 21 drives the fixed box 22 to approach the mold plate 15 groove, positioning the spraying area and preparing for subsequent operations. The electric push rod 3 is activated to push the trigger rod 4. After the trigger rod 4 moves past the rotating rod 25, the rotating rod 25 rotates elastically during the retraction process, and the sealing plate 214 retracts into the fixed groove 24, aligning the fixed hole 215 with the auxiliary hole 216. This allows the spray pipe 23 to connect to the fixed box 22, ensuring that the release agent can be sprayed out smoothly. The spray pipe 23 can spray the pressure plate and the mold plate 15 simultaneously, which greatly improves work efficiency, ensures uniform spraying of the release agent, effectively reduces wear on the mold and pressure plate, extends their service life, reduces production costs, and ensures the quality and stability of subsequent forging operations.
