Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile processing, and specifically to a production mold for aluminum profiles. Background Art

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that applies pressure to the material by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts. In the production of aluminum profiles, it is necessary to be stamped by a stamping die.

[0003] For example, an aluminum profile stamping die disclosed in the publication number "CN221473150U" uses an electric air pump to quickly inflate and pressurize the hollow cavity, and the gas quickly discharges from the air outlet holes. The formed aluminum profile parts are quickly ejected by the gas pressure to realize the function of automatic blanking. The working time of the electric air pump is automatically controlled by a time relay switch. After reaching the set time, the electric air pump is automatically turned off to achieve the effect of energy saving.

[0004] However, although the currently used stamping die uses pneumatic demoulding, it still requires workers to manually take out the formed workpieces from the die. After taking them out, a new aluminum plate is placed on the die for stamping. This operation is somewhat dangerous and is not conducive to continuous processing. Therefore, we propose a production mold for aluminum profiles. Summary of the Invention

[0005] The purpose of the present invention is to provide a production mold for aluminum profiles to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A production mold for aluminum profiles, including a base and a mold body. A stamping assembly is provided on the top of the base. The stamping assembly includes a bracket, a hydraulic cylinder, and a stamping head. A material changing assembly for assisting in loading and unloading is provided inside and on the top of the base and on the mold body. A driven part for assisting in unloading is provided on the material changing assembly. An auxiliary part for preventing jamming during loading is provided on the top of the base and on the mold body.

[0007] Preferably, the material changing assembly includes a material box which is fixed to the top of the base by bolts. An electric push rod is fixed to the left side of the material box. The output shaft of the electric push rod penetrates through the left side of the material box and is fixed to a push plate. A cross bar is fixed to the surface of the output shaft of the electric push rod. The cross bar passes through the material box. A support rod is hinged to the right side of the cross bar. One end of the support rod away from the cross bar is hinged to a vertical rod. The vertical rod penetrates through the top of the base. The bottom of the vertical rod is fixed to the top of a sliding plate. The sliding plate is slidably mounted on the inner wall of the base. A connecting rod is fixed to the top of the sliding plate. The connecting rod passes through the base and the mold body. A top plate member is hinged to the top of the connecting rod. Stack the aluminum plates to be processed in the material box. By starting the electric push rod to drive the push plate to move to the right, one aluminum plate can be pushed to move to the right and fall on the top of the mold body through the material box. During this process, the output shaft of the electric push rod drives the cross bar to move together. The cross bar pushes the vertical rod to move downward through the support rod. The vertical rod drives the sliding plate to move downward. The sliding plate drives the connecting rod and the top plate member to move downward, which will not affect the normal placement of new aluminum plates on the mold body. After stamping, the output shaft of the electric push rod drives the push plate and the cross bar to move back to the left. The cross bar pulls the vertical rod to move upward through the support rod. The vertical rod drives the sliding plate to move upward. The sliding plate drives the connecting rod and the top plate member to move upward. The top plate member ejects the stamped workpiece. There is no need for workers to manually load and unload materials, which can effectively avoid danger and improve the overall work efficiency, facilitating continuous production and processing.

[0008] Preferably, chutes are provided on both the front and back of the material box. A blanking port for the aluminum plates to be discharged is provided on the right side of the material box. There are two groups of cross bars, and the two groups of cross bars are symmetrically arranged on both sides of the output shaft of the electric push rod. The two groups of cross bars can respectively pass through the chutes on the back and front of the material box and can move left and right.

[0009] Preferably, the driven part includes a groove formed on the surface of the ejector plate. A support plate is hinged inside the groove. The sliding plate and the connecting rod are penetrated by a fixing plate and slidably connected to the fixing plate. The bottom of the fixing plate is fixed on the inner wall of the base. A pulling rope is fixed to the top of the fixing plate. The pulling rope passes through the ejector plate, and the end of the pulling rope away from the fixing plate is fixed on the surface of the support plate. A through groove is formed on the surface of the connecting rod, and an L-shaped pressing plate is slidably installed inside the through groove. A return spring is fixed to the bottom of the L-shaped pressing plate, and the end of the return spring away from the L-shaped pressing plate is fixed inside the through groove. An auxiliary elastic piece is fixed to the back of the connecting rod, and the end of the auxiliary elastic piece away from the connecting rod is fixedly connected to the back of the ejector plate. When the connecting rod drives the ejector plate to move upward for a certain distance, since the fixing plate cannot move, the fixing plate can pull the support plate through the pulling rope, causing the support plate to rotate upward around the position hinged to the groove, and the support plate can then lift the bottom of the workpiece, preventing the workpiece from falling and hitting the mold body during ejection, which may damage the workpiece and the mold body. When the connecting rod moves upward a certain distance, the L-shaped pressing plate is abutted by the inner wall of the base, and the L-shaped pressing plate moves downward relative to the connecting rod, and the L-shaped pressing plate no longer abuts against the ejector plate. Under the action of the auxiliary elastic piece, the ejector plate can swing toward the side close to the L-shaped pressing plate around the position hinged to the connecting rod, thereby realizing the dumping of the workpiece. When the connecting rod drives the ejector plate to move downward a certain distance, the pulling rope can no longer pull the support plate, and the support plate can reset under its own gravity. At the same time, the L-shaped pressing plate is no longer abutted by the inner wall of the base. Under the action of the return spring, the L-shaped pressing plate moves upward to press the ejector plate, causing the ejector plate to rotate and reset again, without affecting the normal retraction of the ejector plate into the mold body.

[0010] Preferably, a through hole is formed at the bottom of the mold body, and the ejector plate can coincide with the through hole. When stamping the V-shaped aluminum plate, the aluminum plate will not contact the bottommost part of the inner cavity of the mold body, so normal stamping and forming will not be affected.

[0011] Preferably, the auxiliary part includes a through hole which is opened on the surface of the mold body. A swing plate is hinged inside the through hole. A reset elastic piece is fixed on the surface of the swing plate. One end of the reset elastic piece away from the swing plate is fixedly connected with a fixing rod, and the fixing rod is fixed on the surface of the mold body. A U-shaped sliding rod is slidably installed on the surface of the material box. A top rod is fixed at the top of the U-shaped sliding rod. The U-shaped sliding rod is penetrated by a matching rod and is slidably connected with the matching rod. A connecting spring is fixed at the bottom of the U-shaped sliding rod. One end of the connecting spring away from the U-shaped sliding rod is fixed to the matching rod. A tension spring is fixed inside the U-shaped sliding rod. One end of the tension spring away from the U-shaped sliding rod is fixed on the right side of the mold body. Under the action of the reset elastic piece, the swing plate is in the initial state inside the through hole and does not affect the normal placement of the aluminum plate on the top of the mold body. When the U-shaped sliding rod moves leftward under the action of the tension spring, the U-shaped sliding rod drives the top rod to move together. The top rod can abut against the swing plate, causing the swing plate to swing around the position hinged to the through hole. With the intermittent abutment of the top rod and in cooperation with the reset elastic piece, the swing plate is controlled to swing back and forth, and the aluminum plate placed on the top of the mold body can be knocked and vibrated to ensure that the aluminum plate can maintain a straight state, avoid the phenomenon that the aluminum plate is skewed during placement, resulting in the possible tilting and jamming of the aluminum plate, and further affecting the quality of the subsequent stamping products.

[0012] The U-shaped slide bar is fixed to the upper surface of the material box, and a clamping rod is slidably mounted on the top of the U-shaped slide bar, and a spring 1 is fixed to the left side of the U-shaped slide bar, and one end of the spring 1 is fixed to the clamping rod away from the end of the U-shaped slide bar, and a clamping groove and an insertion groove are provided on the right side of the matching rod, and a fixing block is fixed to the surface of the material box, and the top of the matching rod is inclined. When the output shaft of the electric push rod drives the cross bar to move right, the cross bar can abut on the matching rod, pushing the matching rod and the U-shaped slide bar to move right together. At this time, the U-shaped slide bar moves right with the push rod, and the push rod abuts on the swing plate. At this time, the swing plate is in a state of swinging toward the outside of the mold body, which will not affect the normal placement of the aluminum plate. When the push plate moves to the far right, the aluminum plate is in a state of loading. At this time, the conflicting spring piece is inserted into the insertion groove on the right side of the matching rod, and the matching rod and the conflicting spring piece When the U-shaped slide bar is reset to the left, the clamping bar can be resisted by the fixed block and moved to the right, thereby withdrawing from the clamping slot on the right side of the matching rod to release the limit of the matching rod. Under the action of the connecting spring, the matching rod moves upward and resets. After the electric push rod drives the cross bar to reset, the cross bar resists on the inclined surface at the top of the matching rod, pushing the matching rod to move downward, without affecting the cross bar moving to the left side of the matching rod. When the matching rod is not resisted, it can be reset under the action of the connecting spring, waiting for the next work.

[0013] Preferably, the mold body is fixed on the top of the base, the bracket is fixed on the top of the base, a hydraulic cylinder is fixed on the top of the bracket, the output shaft of the hydraulic cylinder passes through the bracket and is fixed on the top of the punching head, and a material unloading guide plate is fixed on the top of the base. The inclined material unloading guide plate can assist in unloading. When the ejection plate is tilted to unload, the workpiece can fall on the material unloading guide plate and slide away under its own gravity for collection.

[0014] Compared with the prior art, the present invention provides a production mold for aluminum profiles, which has the following beneficial effects:

[0015] 1. The production mold for aluminum profiles, through the set material-changing component, after stamping is completed, the output shaft of the electric push rod drives the push plate and the cross bar to move leftward and return to their positions. The cross bar drives the vertical rod to move upward through the support rod, the vertical rod drives the sliding plate to move upward, the sliding plate drives the connecting rod and the ejecting plate member to move upward, and the ejecting plate member ejects the workpiece formed by stamping. There is no need for workers to manually load and unload materials, which can effectively avoid danger and improve the overall work efficiency, facilitating continuous production and processing.

[0016] 2. The production mold for aluminum profiles, through the set material-changing component and driven part, when the ejecting plate member moves upward to eject the formed workpiece, since the fixed plate cannot move, the fixed plate can pull the supporting plate through the pull rope, causing the supporting plate to rotate upward around the position hinged to the groove. The supporting plate can then lift the bottom of the workpiece, preventing the workpiece from falling and hitting the mold body when ejected, which may damage the workpiece and the mold body.

[0017] 3. The production mold for aluminum profiles, through the set material-changing component and auxiliary part, when the U-shaped sliding rod moves leftward under the action of the tension spring, the U-shaped sliding rod drives the ejector rod to move together. The ejector rod can then abut against the swing plate, causing the swing plate to swing around the position hinged to the through hole. With the intermittent abutment of the ejector rod and in cooperation with the reset elastic piece, the swing plate is controlled to swing back and forth, which can knock and vibrate the aluminum plate placed on the top of the mold body, ensuring that the aluminum plate can maintain a straight state, preventing the aluminum plate from being skewed when placed, which may cause the phenomenon of the aluminum plate being stuck obliquely, thus affecting the quality of the subsequent stamped product.

[0018] 4. The production mold for aluminum profiles, through the set auxiliary part and trigger component, when the output shaft of the electric push rod drives the cross bar to move rightward, the cross bar can abut against the matching rod, pushing the matching rod and the U-shaped sliding rod to move rightward together. At this time, the U-shaped sliding rod drives the ejector rod to move rightward, and the ejector rod abuts against the swing plate. At this time, the swing plate is in a state of swinging outward from the mold body, which will not affect the normal placement of the aluminum plate. When the push plate moves to the rightmost side and the aluminum plate is in the state of being loaded, at this time, the abutting elastic piece is inserted into the insertion groove on the right side of the matching rod, and the matching rod exerts a rightward pushing force on the abutting elastic piece. The abutting elastic piece is squeezed and tilted downward, thereby pushing the matching rod downward. After the matching rod moves downward a certain distance, under the action of spring 1, the clamping rod is inserted into the clamping groove on the right side of the matching rod to limit the matching rod. At this time, under the action of the tension spring, the U-shaped sliding rod can move leftward, thereby controlling the swing plate to correct the aluminum plate, ensuring that the correction operation can only be carried out after the aluminum plate is placed, avoiding affecting the normal placement of the aluminum plate.

[0031] As Figures 1-11As shown in the figure, the present invention provides a technical solution: a production mold for aluminum profiles, including a base 1 and a mold body 6. A stamping assembly is provided on the top of the base 1. The stamping assembly includes a bracket 7, a hydraulic cylinder 8, and a stamping head 9. A material changing assembly 2 for assisting in loading and unloading is provided inside and on the top of the base 1 and on the mold body 6. A driven part 3 for assisting in discharging is provided on the material changing assembly 2. An auxiliary part 4 for preventing jamming during loading is provided on the top of the base 1 and on the mold body 6.

[0032] Among them, the material changing assembly 2 includes a material box 21. The material box 21 is fixed to the top of the base 1 by bolts. An electric push rod 22 is fixed to the left side of the material box 21. The output shaft of the electric push rod 22 penetrates the left side of the material box 21. The output shaft of the electric push rod 22 is fixed to a push plate 23. A cross bar 24 is fixed to the surface of the output shaft of the electric push rod 22. The cross bar 24 passes through the material box 21. A support rod 25 is hinged to the right side of the cross bar 24. One end of the support rod 25 away from the cross bar 24 is hinged to a vertical rod 26. The vertical rod 26 penetrates the top of the base 1. The bottom of the vertical rod 26 is fixed to the top of a sliding plate 27. The sliding plate 27 is slidably installed on the inner wall of the base 1. A connecting rod 28 is fixed to the top of the sliding plate 27. The connecting rod 28 penetrates the base 1 and the mold body 6. The top of the connecting rod 28 is hinged to an ejector plate member 29. Stack the aluminum plates to be processed in the material box 21. By starting the electric push rod 22 to drive the push plate 23 to move to the right, one aluminum plate can be pushed to move to the right and fall on the top of the mold body 6 through the material box 21. During this process, the output shaft of the electric push rod 22 drives the cross bar 24 to move together. The cross bar 24 pushes the vertical rod 26 to move downward through the support rod 25. The vertical rod 26 drives the sliding plate 27 to move downward. The sliding plate 27 drives the connecting rod 28 and the ejector plate member 29 to move downward, which will not affect the normal placement of new aluminum plates on the mold body 6. When the stamping is completed, the output shaft of the electric push rod 22 drives the push plate 23 and the cross bar 24 to move back to the left. The cross bar 24 pulls the vertical rod 26 to move upward through the support rod 25. The vertical rod 26 drives the sliding plate 27 to move upward. The sliding plate 27 drives the connecting rod 28 and the ejector plate member 29 to move upward. The ejector plate member 29 ejects the stamped workpiece. There is no need for staff to manually load and unload, which can effectively avoid danger and improve the overall work efficiency, facilitating continuous production and processing.

[0033] Chute 10 is provided on both the front and back of the material box 21. A blanking port 11 for the aluminum plate to be blanked is provided on the right side of the material box 21. There are two groups of cross bars 24. The two groups of cross bars 24 are symmetrically arranged on both sides of the output shaft of the electric push rod 22. The two groups of cross bars 24 can respectively pass through the chute 10 on the back and front of the material box 21 and can move left and right.

[0034] The driven part 3 includes a groove 31 which is formed on the surface of the ejector plate member 29. A support plate 32 is hinged inside the groove 31. The sliding plate 27 and the connecting rod 28 are penetrated by a fixing plate 33 and are slidably connected to the fixing plate 33. The bottom of the fixing plate 33 is fixed on the inner wall of the base 1. A pull rope 34 is fixed on the top of the fixing plate 33. The pull rope 34 passes through the ejector plate member 29, and one end of the pull rope 34 away from the fixing plate 33 is fixed on the surface of the support plate 32. A through groove 35 is formed on the surface of the connecting rod 28. An L-shaped pressing plate 36 is slidably installed inside the through groove 35. A reset spring 37 is fixed on the bottom of the L-shaped pressing plate 36. One end of the reset spring 37 away from the L-shaped pressing plate 36 is fixed inside the through groove 35. An auxiliary elastic sheet 38 is fixed on the back of the connecting rod 28. One end of the auxiliary elastic sheet 38 away from the connecting rod 28 is fixedly connected to the back of the ejector plate member 29. When the connecting rod 28 drives the ejector plate member 29 to move upward for a certain distance, since the fixing plate 33 cannot move, the fixing plate 33 can pull the support plate 32 through the pull rope 34, so that the support plate 32 rotates upward around the position hinged to the groove 31, and the support plate 32 can lift the bottom of the workpiece, avoiding the situation that when the workpiece is ejected, it falls on the mold body 6 and causes damage to the workpiece and the mold body 6. When the connecting rod 28 moves upward for a certain distance, the L-shaped pressing plate 36 is abutted by the inner wall of the base 1, and the L-shaped pressing plate 36 moves downward relatively on the connecting rod 28, and the L-shaped pressing plate 36 no longer abuts against the ejector plate member 29. Under the action of the auxiliary elastic sheet 38, the ejector plate member 29 can swing toward the side close to the L-shaped pressing plate 36 around the position hinged to the connecting rod 28, so as to realize the dumping of the workpiece. When the connecting rod 28 drives the ejector plate member 29 to move downward for a certain distance, the pull rope 34 can no longer pull the support plate 32, and the support plate 32 can reset under its own gravity. At the same time, the L-shaped pressing plate 36 is no longer abutted by the inner wall of the base 1. Under the action of the reset spring 37, the L-shaped pressing plate 36 moves upward to press the ejector plate member 29, so that the ejector plate member 29 rotates and resets again, and it will not affect the normal retraction of the ejector plate member 29 into the mold body 6.

[0035] A through hole is formed at the bottom of the mold body 6. The ejector plate member 29 can coincide with the through hole, and when stamping the V-shaped aluminum plate, the aluminum plate will not contact the bottommost part of the inner cavity of the mold body 6, so it will not affect the normal stamping and forming.

[0036] The auxiliary part 4 includes a through hole 41 which is opened on the surface of the mold body 6. A swing plate 42 is hinged inside the through hole 41. A reset elastic piece 43 is fixed on the surface of the swing plate 42. One end of the reset elastic piece 43 away from the swing plate 42 is fixedly connected to a fixed rod 44, and the fixed rod 44 is fixed on the surface of the mold body 6. A U-shaped sliding rod 45 is slidably installed on the surface of the material box 21. A push rod 46 is fixed at the top of the U-shaped sliding rod 45. The U-shaped sliding rod 45 is penetrated by a matching rod 47 and is slidably connected to the matching rod 47. A connecting spring 48 is fixed at the bottom of the U-shaped sliding rod 45. One end of the connecting spring 48 away from the U-shaped sliding rod 45 is fixed to the matching rod 47. A tension spring 49 is fixed inside the U-shaped sliding rod 45. One end of the tension spring 49 away from the U-shaped sliding rod 45 is fixed on the right side of the mold body 6. Under the action of the reset elastic piece 43, the swing plate 42 is in the initial state inside the through hole 41 and does not affect the normal placement of the aluminum plate on the top of the mold body 6. When the U-shaped sliding rod 45 moves leftward under the action of the tension spring 49, the U-shaped sliding rod 45 drives the push rod 46 to move together. The push rod 46 can then abut against the swing plate 42, causing the swing plate 42 to swing around the position hinged to the through hole 41. With the intermittent abutment of the push rod 46 and in cooperation with the reset elastic piece 43, the swing plate 42 is controlled to swing back and forth, and the aluminum plate placed on the top of the mold body 6 can be knocked and vibrated, ensuring that the aluminum plate can maintain a straight state and avoiding the phenomenon that the aluminum plate is skewed during placement, which may cause the aluminum plate to be stuck obliquely, thereby affecting the quality of the subsequent stamping finished product.

[0037] The surface of the material box 21, the U-shaped slide bar 45 and the matching rod 47 are provided with a trigger assembly 5, which includes a resisting spring piece 51, which is fixed to the surface of the material box 21, a clamping rod 52 is slidably installed on the top of the U-shaped slide bar 45, a spring 53 is fixed on the left side of the U-shaped slide bar 45, and the end of the spring 53 away from the U-shaped slide bar 45 is fixed to the clamping rod 52, a clamping groove 54 and an insertion groove 55 are provided on the right side of the matching rod 47, a fixing block 56 is fixed on the surface of the material box 21, and the top of the matching rod 47 is inclined. When the output shaft drives the cross bar 24 to move to the right, the cross bar 24 can abut against the matching rod 47, pushing the matching rod 47 and the U-shaped slide bar 45 to move to the right together. At this time, the U-shaped slide bar 45 moves right with the push rod 46, and the push rod 46 abuts against the swing plate 42. At this time, the swing plate 42 is in a state of swinging toward the outside of the mold body 6, and thus will not affect the normal placement of the aluminum plate. When the push plate 23 moves to the far right, the aluminum plate is in a state of loading. At this time, the abutment spring piece 51 is inserted into the insertion groove 55 on the right side of the matching rod 47, and the matching rod 47 abuts against the abutment spring piece 51. The force pushing to the right causes the resisting spring sheet 51 to be squeezed and tilted downward, thereby pushing the matching rod 47 to move downward. After the matching rod 47 moves downward for a certain distance, under the action of the spring 1 53, the clamping rod 52 is inserted into the clamping groove 54 on the right side of the matching rod 47 to limit the matching rod 47. At this time, under the action of the tension spring 49, the U-shaped slide bar 45 can move to the left, thereby controlling the swing plate 42 to adjust the aluminum plate, ensuring that the adjustment operation can be performed only when the aluminum plate is placed, avoiding affecting the normal placement of the aluminum plate. After being in position, the locking rod 52 can be resisted by the fixing block 56 and moved to the right, thereby withdrawing from the locking groove 54 on the right side of the matching rod 47, thereby releasing the limit on the matching rod 47. Under the action of the connecting spring 48, the matching rod 47 moves upward and resets. When the electric push rod 22 drives the cross bar 24 to reset, the cross bar 24 resists against the inclined surface at the top of the matching rod 47, pushing the matching rod 47 to move downward, which will not affect the movement of the cross bar 24 to the left side of the matching rod 47. When the matching rod 47 is not resisted, it can be reset under the action of the connecting spring 48 and wait for the next work.

[0038] The mold body 6 is fixed on the top of the base 1, the bracket 7 is fixed on the top of the base 1, a hydraulic cylinder 8 is fixed on the top of the bracket 7, the output shaft of the hydraulic cylinder 8 passes through the bracket 7 and is fixed on the top of the punch head 9, and a material unloading guide plate 12 is fixed on the top of the base 1. The inclined material unloading guide plate 12 can assist in unloading. When the ejection plate 29 is tilted to unload, the workpiece can fall on the material unloading guide plate 12 and slide away under the action of its own gravity for collection.

[0039] When processing aluminum plates, the aluminum plates are neatly stacked from the top of the material box 21 and placed in the material box 21. The electric push rod 22 is started, and the electric push rod 22 controls the push plate 23 to move to the right, so that an aluminum plate can be pushed to the right and fall on the top of the mold body 6 through the material box 21. In this process, the output shaft of the electric push rod 22 drives the cross bar 24 to move together, and the cross bar 24 drives the vertical rod 26 to move downward through the support rod 25. The vertical rod 26 moves downward with the slide plate 27, and the slide plate 27 drives the connecting rod 28 and the ejector plate 29 to move downward. The movement will not affect the normal placement of the new aluminum plate on the mold body 6. When the connecting rod 28 moves the ejection plate 29 downward for a certain distance, the pull rope 34 can no longer continue to pull the support plate 32, and the support plate 32 can be reset under the action of its own gravity. At the same time, the L-shaped extrusion plate 36 is no longer resisted by the inner wall of the base 1. Under the action of the reset spring 37, the L-shaped extrusion plate 36 moves upward to squeeze the ejection plate 29, so that the ejection plate 29 rotates and resets again, which will not affect the normal retraction of the ejection plate 29 into the mold body 6.

[0040] When the stamping is completed, the output shaft of the electric push rod 22 drives the push plate 23 and the cross bar 24 to move back to the left, the cross bar 24 pulls the vertical rod 26 to move upward through the support rod 25, the vertical rod 26 drives the slide plate 27 to move upward, the slide plate 27 drives the connecting rod 28 and the ejector plate 29 to move upward, and the ejector plate 29 ejects the stamped workpiece. There is no need for manual loading and unloading of materials by staff, which can effectively avoid danger, improve the overall work efficiency, and is conducive to continuous production and processing.

[0041] The ejection plate 29 is no longer in contact with the ejection plate 29. Under the action of the auxiliary spring piece 38, the ejection plate 29 can be swung to the side close to the L-shaped extrusion plate 36 at the position where it is hinged to the connecting rod 28, thereby tipping the workpiece, and the workpiece falls on the blanking guide plate 12 and slides away for collection.

[0042] When the output shaft of the electric push rod 22 drives the cross bar 24 to move to the right, the cross bar 24 can abut against the mating rod 47, pushing the mating rod 47 and the U-shaped slide rod 45 to move to the right together. At this time, the U-shaped slide rod 45 drives the ejector rod 46 to move to the right, and the ejector rod 46 abuts against the swing plate 42. At this time, the swing plate 42 is in a state of swinging outward from the mold body 6, and thus will not affect the normal placement of the aluminum plate. When the push plate 23 moves to the rightmost side and the aluminum plate is in a state of being loaded, at this time, the abutting elastic piece 51 is inserted into the insertion groove 55 on the right side of the mating rod 47, and the mating rod 47 exerts a force to push the abutting elastic piece 51 to the right. The abutting elastic piece 51 is squeezed and tilted downward, thereby pushing the mating rod 47 to move downward. After the mating rod 47 moves downward a certain distance, under the action of the first spring 53, the latch 52 is inserted into the card slot 54 on the right side of the mating rod 47 to limit the mating rod 47. At this time, under the action of the tension spring 49, the U-shaped slide rod 45 can move to the left, and the U-shaped slide rod 45 drives the ejector rod 46 to move together. The ejector rod 46 can abut against the swing plate 42, so that the swing plate 42 swings around the position hinged to the through hole 41. With the intermittent abutment of the ejector rod 46 and in cooperation with the reset elastic piece 43, the swing plate 42 is controlled to swing back and forth, and the aluminum plate placed on the top of the mold body 6 can be knocked and vibrated to ensure that the aluminum plate can maintain a flat state and avoid the phenomenon that the aluminum plate is skewed during placement, resulting in the aluminum plate being stuck obliquely, which will affect the quality of the subsequent stamping products.

[0043] After the U-shaped slide rod 45 is reset to the left, the latch 52 can be abutted by the fixed block 56 and move to the right, so as to withdraw from the card slot 54 on the right side of the mating rod 47, realizing the release of the limit on the mating rod 47. Under the action of the connecting spring 48, the mating rod 47 moves upward to reset. When the electric push rod 22 drives the cross bar 24 to reset, the cross bar 24 abuts against the inclined surface on the top of the mating rod 47, pushing the mating rod 47 to move downward, without affecting the cross bar 24 moving to the left side of the mating rod 47. When the mating rod 47 is not abutted, it can be reset under the action of the connecting spring 48 and wait for the next operation.

[0044] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
