Description

Technical Field

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

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts. Aluminum profiles need to be stamped using stamping dies during production.

[0003] For example, an aluminum profile stamping die published with the announcement number "CN221473150U" uses an electric air pump to quickly inflate and pressurize the hollow cavity, and the gas is quickly discharged from the air outlet. The gas pressure is used to quickly eject the formed aluminum profile, realizing the function of automatic material removal. The time relay switch is used to automatically control the working time of the electric air pump. After the set time is reached, the electric air pump is automatically turned off, thereby achieving an energy-saving effect.

[0004] However, although the stamping dies currently used are pneumatically demolded, the staff still needs to manually remove the formed workpiece from the die, and then place a new aluminum plate on the die for stamping. This operation is dangerous and not conducive to continuous processing. For this reason, we propose a production die for aluminum profiles. Summary of the invention

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

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a production mold for aluminum profiles, comprising a base and a mold body, a stamping assembly is arranged on the top of the base, the stamping assembly comprises a bracket, a hydraulic cylinder and a stamping head, a material changing assembly for assisting loading and unloading is arranged inside, on the top of the base and on the mold body, a driven part for assisting unloading is arranged on the material changing assembly, and an auxiliary part for preventing loading from getting stuck is arranged on the top of the base and the mold body.

[0007] Preferably, the material changing assembly comprises a material box, which is fixed to the top of the base by bolts, an electric push rod is fixed on the left side of the material box, the output shaft of the electric push rod passes through the left side of the material box, the output shaft of the electric push rod is fixed to the push plate, a cross bar is fixed on the surface of the output shaft of the electric push rod, the cross bar passes through the material box, a support rod is hinged on the right side of the cross bar, one end of the support rod away from the cross bar is hinged to the vertical rod, the vertical rod passes through the top of the base, the bottom of the vertical rod is fixed to the top of the slide plate, the slide plate is slidably mounted on the inner wall of the base, a connecting rod is fixed on the top of the slide plate, the connecting rod passes through the base and the mold body, and the top of the connecting rod is hinged with an ejection plate, the aluminum plates to be processed are stacked and placed in the material box, and the electric push rod is started to bring When the push plate moves to the right, an aluminum plate can be pushed 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, and the cross bar pushes the vertical bar downward through the support rod, and the vertical bar moves downward with the slide plate, and the slide plate drives the connecting rod and the ejector plate to move downward, which will not affect the normal placement of the new aluminum plate on the mold body. When the stamping is completed, the output shaft of the electric push rod drives the push plate and the cross bar to move back to the left, and the cross bar pulls the vertical bar upward through the support rod, and the vertical bar drives the slide plate upward, and the slide plate drives the connecting rod and the ejector plate to move upward, and the ejector plate ejects the stamped workpiece. There is no need for staff to manually load and unload materials, which can effectively avoid danger, improve the overall work efficiency, and is conducive to continuous production and processing.

[0008] Preferably, slide grooves are provided on the front and back of the material box, and a discharge port for unloading aluminum plates is provided on the right side of the material box. Two groups of cross bars are provided, 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 pass through the slide grooves on the back and front of the material box respectively, and can move left and right.

[0009] The cam is secured to the bottom of the support plate and has a cam portion that is secured to the bottom of the support plate and has a cam portion that is secured to the bottom of the support plate. The hinged position of the groove rotates upward, and the support plate can lift the bottom of the workpiece to prevent the workpiece from falling and hitting the mold body during ejection, causing damage to the workpiece and the mold body. When the connecting rod moves upward for a certain distance, the L-shaped extrusion plate is resisted by the inner wall of the base, and the L-shaped extrusion plate moves downward in disguise on the connecting rod, and the L-shaped extrusion plate no longer resists the ejection plate. Under the action of the auxiliary spring, the ejection plate can swing to the side close to the L-shaped extrusion plate at the position hinged with the connecting rod, thereby dumping the workpiece. When the connecting rod moves downward for a certain distance with the ejection plate, the pull rope can no longer continue to pull the support plate, and the support plate can be reset under the action of its own gravity, and at the same time, the L-shaped extrusion plate is no longer resisted by the inner wall of the base. Under the action of the reset spring, the L-shaped extrusion plate moves upward to squeeze the ejection plate, so that the ejection plate rotates and resets again, which will not affect the normal retraction of the ejection plate into the mold body.

[0010] Preferably, a through hole is opened at the bottom of the mold body, and the ejector plate can overlap with the through hole, and when stamping the V-shaped aluminum plate, the aluminum plate will not contact the bottom of the inner cavity of the mold body, so it will not affect the normal stamping forming.

[0011] Preferably, the auxiliary part includes a through hole, which is opened on the surface of the mold body, and a swing plate is hinged on the inner side of the through hole, and a reset spring is fixed on the surface of the swing plate, and the end of the reset spring away from the swing plate is fixedly connected to the fixed rod, and the fixed rod is fixed to the surface of the mold body, and a U-shaped sliding rod is slidably installed on the surface of the material box, and a top rod is fixed on the top of the U-shaped sliding rod, and the U-shaped sliding rod is penetrated by the matching rod and slidably connected with the matching rod, and a connecting spring is fixed on the bottom of the U-shaped sliding rod, and the end of the connecting spring away from the U-shaped sliding rod is fixed to the matching rod, and a tension spring is fixed on the inner side of the U-shaped sliding rod, and the 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 spring, the initial state of the swing plate is in 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 slide bar moves to the left under the action of the tension spring, the U-shaped slide bar moves with the push rod, and the push rod can abut against the swing plate, so that the swing plate swings at the position hinged with the through hole. With the intermittent abutment of the push rod and in conjunction with the reset spring, 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 remain straight and avoid the aluminum plate from tilting when placed, which may cause the aluminum plate to tilt and get stuck, thereby affecting the quality of 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 the aluminum profile has a material changing assembly. After the stamping is completed, 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 bar upward through the support rod, and the vertical bar drives the slide plate upward. The slide plate drives the connecting rod and the ejector plate to move upward. The ejector plate ejects the stamped workpiece. There is no need for manual loading and unloading of materials by the staff, which can effectively avoid danger, improve the overall work efficiency, and is conducive to continuous production and processing.

[0016] 2. The production mold for the aluminum profile has a material changing assembly and a driven part. When the ejection plate moves upward to eject the formed workpiece, since the fixed plate cannot move, the fixed plate can pull the support plate through a pull rope, so that the support plate rotates upward at the position hinged with the groove. The support plate can lift the bottom of the workpiece to prevent the workpiece from falling and hitting the mold body during ejection, causing damage to the workpiece and the mold body.

[0017] 3. The production mold for the aluminum profile is provided with a material changing assembly and an auxiliary part. When the U-shaped slide bar moves to the left under the action of the tension spring, the U-shaped slide bar moves with the push rod, and the push rod can abut against the swing plate, so that the swing plate swings at the position hinged with the through hole. With the intermittent abutment of the push rod and in cooperation with the reset spring, 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 remain straight, avoid the aluminum plate from tilting when placed, and cause the aluminum plate to tilt and get stuck, thereby affecting the quality of the subsequent stamping products.

[0018] 4. The production mold for the aluminum profile is provided with an auxiliary part and a trigger component. When the output shaft of the electric push rod drives the cross bar to move to the right, the cross bar can contact the matching rod, pushing the matching rod and the U-shaped slide bar to move to the right together. At this time, the U-shaped slide bar moves to the right with the push rod, and the push rod contacts the swing plate. At this time, the swing plate is in a state of swinging toward the outside of the mold body, and thus 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 resisting spring is inserted into the insertion groove on the right side of the matching rod, and the matching rod causes a force to push the resisting spring to the right. The resisting spring is squeezed and tilted downward, thereby pushing the matching rod to move downward. After the matching rod moves downward for 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 slide bar can move to the left, thereby controlling the swing plate to adjust the aluminum plate, ensuring that the adjustment operation can be performed only after the aluminum plate is placed, thereby avoiding affecting the normal placement of the aluminum plate.

DETAILED DESCRIPTION

[0031] like Figure 1-Figure 11As shown, 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 arranged on the top of the base 1, the stamping assembly includes a bracket 7, a hydraulic cylinder 8 and a punch head 9, a material changing assembly 2 for assisting loading and unloading is arranged inside the base 1 and on the top and the mold body 6, a driven part 3 for assisting unloading is arranged on the material changing assembly 2, and an auxiliary part 4 for preventing loading from getting stuck is arranged on the top of the base 1 and the mold body 6.

[0032] The material changing assembly 2 comprises a material box 21, which 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 passes through 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. The end of the support rod 25 away from the cross bar 24 is hinged to a vertical rod 26. The vertical rod 26 passes through the top of the base 1. The bottom of the vertical rod 26 is fixed to the top of a slide plate 27. The slide plate 27 is slidably mounted on the inner wall of the base 1. A connecting rod 28 is fixed to the top of the slide plate 27. The connecting rod 28 passes through the base 1 and the mold body 6. The top of the connecting rod 28 is hinged with an ejection plate 29. The aluminum plates to be processed are stacked and placed in the material box 21. The push plate 23 is driven to move to the right by starting the electric push rod 22. That is, an 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, and the cross bar 24 pushes the vertical rod 26 to move downward through the support rod 25, and the vertical rod 26 moves downward with the slide plate 27, and the slide plate 27 drives the connecting rod 28 and the ejection plate 29 to move downward, which will not affect the normal placement of the new aluminum plate 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, and the cross bar 24 pulls the vertical rod 26 to move upward through the support rod 25, and the vertical rod 26 drives the slide plate 27 to move upward, and the slide plate 27 drives the connecting rod 28 and the ejection plate 29 to move upward, and the ejection plate 29 ejects the stamped workpiece. There is no need for staff to manually load and unload materials, which can effectively avoid danger, improve the overall work efficiency, and is conducive to continuous production and processing.

[0033] The front and back of the material box 21 are provided with slide grooves 10, and the right side of the material box 21 is provided with a discharge port 11 for unloading aluminum plates. Two groups of cross bars 24 are provided, and 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 pass through the slide grooves 10 on the back and front of the material box 21 respectively, and can move left and right.

[0034] The driven part 3 includes a groove 31, which is provided on the surface of the ejection plate 29, and a support plate 32 is hinged on the inner side of the groove 31. The slide plate 27 and the connecting rod 28 are penetrated by the fixed plate 33 and are slidably connected with the fixed plate 33. The bottom of the fixed plate 33 is fixed on the inner wall of the base 1, and a pull rope 34 is fixed on the top of the fixed plate 33. The pull rope 34 passes through the ejection plate 29, and one end of the pull rope 34 away from the fixed plate 33 is fixed on the surface of the support plate 32. A through groove 35 is provided on the surface of the connecting rod 28, and a sliding installation is installed on the inner side of the through groove 35. There is an L-shaped extrusion plate 36, and a return spring 37 is fixed at the bottom of the L-shaped extrusion plate 36. The end of the return spring 37 away from the L-shaped extrusion plate 36 is fixed to the inner side of the through groove 35. An auxiliary spring 38 is fixed to the back of the connecting rod 28. The end of the auxiliary spring 38 away from the connecting rod 28 is fixedly connected to the back of the ejection plate 29. When the connecting rod 28 moves upward with the ejection plate 29 for a distance, since the fixed plate 33 cannot move, the fixed plate 33 can pull the support plate 32 through the pull rope 34, so that the support plate 32 is aligned with the groove 35. 1 is hinged upward, and the support plate 32 can lift the bottom of the workpiece to prevent the workpiece from falling and hitting the mold body 6 during ejection, causing damage to the workpiece and the mold body 6. When the connecting rod 28 moves upward for a certain distance, the L-shaped extrusion plate 36 is resisted by the inner wall of the base 1, and the L-shaped extrusion plate 36 moves downward on the connecting rod 28 in a disguised manner. The L-shaped extrusion plate 36 no longer resists the ejection plate 29. Under the action of the auxiliary spring piece 38, the ejection plate 29 can move closer to the L-shaped position where it is hinged with the connecting rod 28. One side of the extrusion plate 36 swings to tip the workpiece. 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.

[0035] A through hole is provided at the bottom of the mold body 6, and the ejector plate 29 can overlap with the through hole. When stamping the V-shaped aluminum plate, the aluminum plate will not contact the bottom of the inner cavity of the mold body 6, so it will not affect the normal stamping 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 on the inner side of the through hole 41. A reset spring 43 is fixed on the surface of the swing plate 42. The end of the reset spring 43 away from the swing plate 42 is fixedly connected to a fixed rod 44. The fixed rod 44 is fixed to the surface of the mold body 6. A U-shaped slide bar 45 is slidably installed on the surface of the material box 21. A top rod 46 is fixed on the top of the U-shaped slide bar 45. The U-shaped slide bar 45 is penetrated by a matching rod 47 and is slidably connected to the matching rod 47. A connecting spring 48 is fixed to the bottom of the U-shaped slide bar 45. The end of the connecting spring 48 away from the U-shaped slide bar 45 is fixed to the matching rod 47. A tension spring 49 is fixed on the inner side of the U-shaped slide bar 45. The end of the tension spring 49 away from the U-shaped slide bar 45 is fixed to the mold On the right side of the main body 6, under the action of the reset spring 43, the initial state of the swing plate 42 is in the through hole 41, and it will not affect the normal placement of the aluminum plate on the top of the mold body 6. When the U-shaped slide bar 45 moves to the left under the action of the tension spring 49, the U-shaped slide bar 45 moves with the push rod 46, and the push rod 46 can abut against the swing plate 42, so that the swing plate 42 swings at the position hinged with the through hole 41. With the intermittent abutment of the push rod 46 and in cooperation with the reset spring 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 remain straight and avoid the aluminum plate from tilting when placed, which may cause the aluminum plate to tilt and get stuck, thereby affecting the quality of the subsequent stamping products.

[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 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, which 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 resistance spring piece 51 is inserted into the insertion groove 55 on the right side of the matching rod 47, and the matching rod 47 causes a force to push the resistance spring piece 51 to the right. The resistance spring piece 51 is 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 spring 1 53, the locking rod 52 is inserted into the locking 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, and the U-shaped slide bar 45 moves with the push rod 46, and the push rod 46 can abut against the swing plate 42, so that the swing plate 42 swings at the position hinged with the through hole 41. With the intermittent abutment of the push rod 46 and in cooperation with the reset spring 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 remain straight and avoid the aluminum plate from being skewed when placed, which may cause the aluminum plate to tilt and get stuck, thereby affecting the quality of the subsequent stamping products.

[0043] When the U-shaped slide bar 45 is reset to the left, the locking rod 52 can be resisted by the fixed 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 on 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.

[0044] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
