Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, specifically to a production mold for aluminum profiles. Background Technology

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

[0003] For example, an aluminum profile stamping die disclosed in announcement number "CN221473150U" uses an electric air pump to quickly inflate and pressurize the hollow cavity. The gas is quickly discharged from the air outlet, and the gas pressure is used to quickly eject the formed aluminum profile part, realizing the function of automatic unloading. The working time of the electric air pump is automatically controlled by a time relay switch. After the set time is reached, the electric air pump is automatically turned off, which achieves the effect of energy saving.

[0004] Although the stamping dies currently used are pneumatically demolded, workers still need to manually remove the formed workpiece from the die. After removal, a new aluminum plate is placed on the die for stamping. This operation is dangerous and not conducive to continuous processing. Therefore, we propose a production die for aluminum profiles. Summary of the Invention

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

[0006] To achieve the above objectives, the present invention provides the following technical solution: a production mold for aluminum profiles, comprising a base and a mold body, wherein a stamping assembly is provided on the top of the base, the stamping assembly comprising a bracket, a hydraulic cylinder and a stamping head, and a material changing assembly for assisting loading and unloading is provided inside the base, on the top and on the mold body, wherein the material changing assembly is provided with a driven part for assisting unloading, and an auxiliary part for preventing loading jamming 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 bolted to the top of the base. An electric push rod is fixed to the left side of the material box, and 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 a push plate. A crossbar is fixed to the surface of the output shaft of the electric push rod, and the crossbar passes through the material box. A support rod is hinged to the right side of the crossbar, and the end of the support rod away from the crossbar is hinged to a vertical rod. The vertical rod passes through the top of the base, and 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, and the connecting rod passes through the base and the mold body. An ejector plate is hinged to the top of the connecting rod. The aluminum plates to be processed are stacked and placed in the material box, and the electric push rod is activated to drive the material changing assembly. Moving the pusher plate to the right pushes an aluminum plate to the right, which then falls onto the top of the mold body via the material box. During this process, the output shaft of the electric pusher rod drives the horizontal bar to move together. The horizontal bar pushes the vertical bar downward through the support rod. The vertical bar moves the slide plate downward, which in turn moves the connecting rod and the ejector plate downward. This process does not affect the normal placement of new aluminum plates on the mold body. After stamping is completed, the output shaft of the electric pusher rod drives the pusher plate and the horizontal bar to move back to their original positions to the left. The horizontal bar pulls the vertical bar upward through the support rod. The vertical bar moves the slide plate upward, which in turn moves the connecting rod and the ejector plate upward. The ejector plate then ejects the stamped workpiece. This eliminates the need for manual loading and unloading by operators, effectively avoiding potential dangers and improving overall work efficiency, which is beneficial for continuous production.

[0008] Preferably, the material box has sliding grooves on both the front and back, and a feeding port for feeding aluminum plates is provided on the right side of the material box. There are two sets of crossbars, which are symmetrically arranged on both sides of the output shaft of the electric push rod. The two sets of crossbars can pass through the sliding grooves on the back and front of the material box respectively, 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 to the inner side of the groove. The sliding plate and the connecting rod are penetrated by a fixed plate and slidably connected to the fixed plate. The bottom of the fixed plate is fixed to the inner wall of the base. A pull rope is fixed to the top of the fixed plate. The pull rope passes through the ejector plate. The end of the pull rope away from the fixed plate is fixed to the surface of the support plate. A through groove is formed on the surface of the connecting rod. An L-shaped pressing plate is slidably installed on the inner side of the through groove. A return spring is fixed to the bottom of the L-shaped pressing plate. The end of the return spring away from the L-shaped pressing plate is fixed to the inner side of the through groove. An auxiliary spring is fixed to the back of the connecting rod. The end of the auxiliary spring away from the connecting rod is fixedly connected to the back of the ejector plate. When the connecting rod moves the ejector plate upward a certain distance, since the fixed plate cannot move, the fixed plate can pull the support plate by the pull rope, so that the support plate and... When the hinged position of the groove rotates upward, the support plate can lift the bottom of the workpiece, preventing it from falling and hitting the mold body during ejection, thus avoiding damage to both the workpiece and the mold body. After the connecting rod moves upward a certain distance, the L-shaped extrusion plate is pressed against the inner wall of the base. The L-shaped extrusion plate moves downward on the connecting rod, and no longer presses against the ejector plate. Under the action of the auxiliary spring, the ejector plate can swing towards the side of the L-shaped extrusion plate at the hinged position of the connecting rod, thereby tilting the workpiece. After the connecting rod moves downward a certain distance with the ejector plate, the pull rope can no longer pull the support plate, and the support plate can reset under its own weight. At the same time, the L-shaped extrusion plate is no longer pressed against the inner wall of the base. Under the action of the return spring, the L-shaped extrusion plate moves upward to press against the ejector plate, causing the ejector plate to rotate and reset, without affecting the normal retraction of the ejector plate into the mold body.

[0010] Preferably, the bottom of the mold body has a through hole, the ejector plate can overlap 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 and forming.

[0011] Preferably, the auxiliary part includes a through hole, which is formed on the surface of the mold body. A swing plate is hinged to the inner side of the through hole. A reset spring is fixed to the surface of the swing plate. The end of the reset spring away from the swing plate is fixedly connected to a fixed rod. The fixed rod is fixed to the surface of the mold body. A U-shaped slide rod is slidably mounted on the surface of the material box. A top rod is fixed to the top of the U-shaped slide rod. The U-shaped slide rod is penetrated by a mating rod and slidably connected to the mating rod. A connecting spring is fixed to the bottom of the U-shaped slide rod. The end of the connecting spring away from the U-shaped slide rod is fixed to the mating rod. A tension spring is fixed to the inner side of the U-shaped slide rod. The end of the tension spring away from the U-shaped slide rod is fixed... On the right side of the mold body, under the action of the reset spring, the swing plate is initially positioned inside the through hole and will 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 together with the push rod, which then abuts against the swing plate, causing the swing plate to swing at the hinge position with the through hole. With the intermittent contact of the push rod and in conjunction with the reset spring, the swing plate is controlled to swing back and forth, which can tap and vibrate the aluminum plate placed on the top of the mold body, ensuring that the aluminum plate remains flat and preventing it from tilting during placement, which could cause the aluminum plate to tilt and get stuck, thus affecting the quality of the subsequent stamped products.

[0012] Preferably, the surface of the material box, the U-shaped slide bar, and the mating rod are provided with triggering components. The triggering components include a contact spring, which is fixed to the surface of the material box. A locking rod is slidably installed on the top of the U-shaped slide bar. A spring is fixed on the left side of the U-shaped slide bar, and the end of the spring away from the U-shaped slide bar is fixed to the locking rod. A locking groove and an insertion groove are provided on the right side of the mating rod. A fixing block is fixed on the surface of the material box. The top of the mating rod is inclined. When the output shaft of the electric push rod drives the crossbar to move to the right, the crossbar can abut against the mating rod, pushing the mating 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 abuts against the swing plate. At this time, the swing plate is in a state of swinging outward from the mold body, so as not to affect the normal placement of the aluminum plate. When the push plate moves to the rightmost position, the aluminum plate is in a state of being loaded. At this time, the contact spring is inserted into the insertion groove on the right side of the mating rod, and the mating rod abuts against the contact spring. The force pushing to the right causes the contact spring to be squeezed downwards, thus pushing the mating rod downwards. After the mating rod moves downwards a certain distance, under the action of spring one, the locking rod inserts into the slot on the right side of the mating rod, limiting the mating rod. At this time, under the action of the tension spring, the U-shaped slide rod can move to the left, thereby controlling the swing plate to straighten the aluminum plate. This ensures that the straightening operation can only be performed after the aluminum plate is placed, avoiding affecting the normal placement of the aluminum plate. When the U-shaped slide rod returns to its left position, the locking rod can be pushed to the right by the fixing block, thus exiting from the slot on the right side of the mating rod and releasing the limitation on the mating rod. Under the action of the connecting spring, the mating rod moves upwards to reset. When the electric push rod drives the crossbar to reset, the crossbar abuts against the inclined surface at the top of the mating rod, pushing the mating rod downwards without affecting the crossbar's movement to the left side of the mating rod. When the mating rod is no longer abutted, it can reset under the action of the connecting spring, waiting for the next operation.

[0013] Preferably, the mold body is fixed to the top of the base, the bracket is fixed to the top of the base, a hydraulic cylinder is fixed to the top of the bracket, the output shaft of the hydraulic cylinder passes through the bracket and is fixed to the top of the stamping head, and a feeding guide plate is fixed to the top of the base. The inclined feeding guide plate can assist in unloading. When the ejected plate is tilted for unloading, the workpiece can fall on the feeding 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 this aluminum profile uses a material changing assembly. After stamping is completed, the output shaft of the electric push rod drives the push plate and crossbar to move to the left and return to their original position. The crossbar pulls the vertical bar upward through the support rod, the vertical bar drives the slide plate upward, the slide plate drives the connecting rod and the ejector plate upward, and the ejector plate ejects the stamped workpiece. There is no need for manual loading and unloading by the staff, which can effectively avoid danger and improve the overall work efficiency, which is conducive to continuous production and processing.

[0016] 2. The production mold for this aluminum profile, through the set material changing component and driven part, when the ejector plate moves upward to eject the formed workpiece, since the fixed plate cannot move, the fixed plate can pull the support plate through the pull rope, so that the support plate rotates upward at the position of hinge with the groove. The support plate can then lift the bottom of the workpiece, avoiding the workpiece falling and hitting the mold body during ejection, causing damage to the workpiece and the mold body.

[0017] 3. The production mold for this aluminum profile, through the set material changing component and 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 together with the push rod, and the push rod can then 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, which can knock and vibrate the aluminum plate placed on the top of the mold body, ensuring that the aluminum plate can remain flat and avoiding the aluminum plate being tilted when placed, which may cause the aluminum plate to tilt and get stuck, thus affecting the quality of the subsequent stamped finished products.

[0018] 4. The production mold for this aluminum profile, through the auxiliary part and triggering component, when the output shaft of the electric push rod drives the crossbar to move to the right, the crossbar can abut against the mating rod, pushing the mating rod and the U-shaped slide rod to move to the right together. At this time, the U-shaped slide rod moves to the right with the push rod, and the push rod abuts against the swing plate. At this time, the swing plate is in a state of swinging outward from the mold body, thus not affecting the normal placement of the aluminum plate. When the push plate moves to the rightmost position, the aluminum plate is in the state of being loaded. At this time, the contact spring is inserted into the insertion slot on the right side of the mating rod. The mating rod exerts a rightward pushing force on the contact spring, and the contact spring is squeezed and tilted downward, thereby pushing the mating rod to move downward. After the mating rod moves downward a certain distance, under the action of spring one, the locking rod is inserted into the locking slot on the right side of the mating rod to limit the mating rod. At this time, under the action of the tension spring, the U-shaped slide rod can move to the left, thereby controlling the swing plate to straighten the aluminum plate, ensuring that the straightening operation can only be performed after the aluminum plate is placed, avoiding affecting the normal placement of the aluminum plate.

[0031] like Figures 1-11As 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 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 loading and unloading is provided inside the base 1, on the top and on the mold body 6. A driven part 3 for assisting unloading is provided on the material changing assembly 2. An auxiliary part 4 for preventing loading jamming is provided on the top of the base 1 and on the mold body 6.

[0032] The material changing assembly 2 includes a material box 21, which is bolted to the top of the base 1. An electric push rod 22 is fixed to the left side of the material box 21, and 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 the push plate 23. A crossbar 24 is fixed to the surface of the output shaft of the electric push rod 22, and the crossbar 24 passes through the material box 21. A support rod 25 is hinged to the right side of the crossbar 24, and the end of the support rod 25 away from the crossbar 24 is hinged to a vertical rod 26. The vertical rod 26 passes through the top of the base 1, and the bottom of the vertical rod 26 is fixed to the top of the 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, and the connecting rod 28 passes through the base 1 and the mold body 6. An ejector plate 29 is hinged to the top of the connecting rod 28. The aluminum plates to be processed are stacked and placed in the material box 21. By activating the electric push rod 22, the push plate 23 is moved to the right. An aluminum plate can be pushed to the right and placed on top of the mold body 6 via the material box 21. During this process, the output shaft of the electric push rod 22 drives the horizontal bar 24 to move together. The horizontal bar 24 pushes the vertical bar 26 downward through the support rod 25. The vertical bar 26 moves the slide plate 27 downward. The slide plate 27 drives the connecting rod 28 and the ejector plate 29 downward. This will not affect the normal placement of the new aluminum plate on the mold body 6. After the stamping is completed, the output shaft of the electric push rod 22 drives the push plate 23 and the horizontal bar 24 to move to the left to return to their original positions. The horizontal bar 24 pulls the vertical bar 26 upward through the support rod 25. The vertical bar 26 drives the slide plate 27 upward. The slide plate 27 drives the connecting rod 28 and the ejector plate 29 upward. The ejector plate 29 ejects the stamped workpiece. There is no need for manual loading and unloading by the operator, which can effectively avoid danger and improve the overall work efficiency, which is conducive to continuous production and processing.

[0033] The material box 21 has sliding grooves 10 on both the front and back. The material box 21 has a feeding port 11 on the right side for feeding aluminum plates. There are two sets of crossbars 24, which are symmetrically arranged on both sides of the output shaft of the electric push rod 22. The two sets of crossbars 24 can pass through the sliding 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 formed on the surface of the ejector plate 29. A support plate 32 is hinged to the inner side of the groove 31. The slide 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 to the inner wall of the base 1, and a pull rope 34 is fixed to the top of the fixing plate 33. The pull rope 34 passes through the ejector plate 29, and the end of the pull rope 34 away from the fixing plate 33 is fixed to the surface of the support plate 32. A through groove 35 is formed on the surface of the connecting rod 28, and the inner side of the through groove 35 is slidably installed. An L-shaped extrusion plate 36 is provided, and a return spring 37 is fixed to 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 inside 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 ejector plate 29. When the connecting rod 28 moves the ejector plate 29 upward a certain 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. When the hinged position rotates upward, the support plate 32 can lift the bottom of the workpiece, preventing it from falling and hitting the mold body 6 during ejection, thus avoiding damage to both the workpiece and the mold body 6. After the connecting rod 28 moves upward a certain distance, the L-shaped extrusion plate 36 is pressed against the inner wall of the base 1. The L-shaped extrusion plate 36 moves downward on the connecting rod 28 in a de facto manner, and no longer presses against the ejector plate 29. Under the action of the auxiliary spring 38, the ejector plate 29 can move closer to the L-shaped position hinged with the connecting rod 28. The extrusion plate 36 swings to one side, thereby tilting the workpiece. When the connecting rod 28 moves the ejector plate 29 downward a certain distance, the pull rope 34 can no longer pull the support plate 32. The support plate 32 can then reset under its own weight. At the same time, the L-shaped extrusion plate 36 is no longer in contact with the inner wall of the base 1. Under the action of the reset spring 37, the L-shaped extrusion plate 36 moves upward to press the ejector plate 29, causing the ejector plate 29 to rotate and reset again. This will not affect the normal retraction of the ejector plate 29 into the mold body 6.

[0035] The bottom of the mold body 6 has a through hole, and the ejector plate 29 can overlap 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 and forming.

[0036] The auxiliary part 4 includes a through hole 41, which is formed on the surface of the mold body 6. A swing plate 42 is hinged to the inside of the through hole 41. A reset spring 43 is fixed to 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 rod 45 is slidably mounted on the surface of the material box 21. A top rod 46 is fixed to the top of the U-shaped slide rod 45. The U-shaped slide rod 45 is penetrated by a mating rod 47 and is slidably connected to the mating rod 47. A connecting spring 48 is fixed to the bottom of the U-shaped slide rod 45. The end of the connecting spring 48 away from the U-shaped slide rod 45 is fixed to the mating rod 47. A tension spring 49 is fixed to the inside of the U-shaped slide rod 45. The end of the tension spring 49 away from the U-shaped slide rod 45 is fixed to the mold. On the right side of the body 6, under the action of the reset spring 43, the swing plate 42 is initially in the through hole 41, which does 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 together 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 conjunction with the reset spring 43, the swing plate 42 can be controlled to swing back and forth, which can knock and vibrate the aluminum plate placed on the top of the mold body 6, ensuring that the aluminum plate can remain flat and avoiding the aluminum plate from being tilted when placed, which may cause the aluminum plate to tilt and get stuck, thus affecting the quality of the subsequent stamped products.

[0037] Triggering components 5 are provided on the surface of the material box 21, the U-shaped slide bar 45, and the mating rod 47. The triggering components 5 include a contact spring 51, which is fixed to the surface of the material box 21. A locking rod 52 is slidably mounted 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 locking rod 52. A locking groove 54 and an insertion groove 55 are provided on the right side of the mating rod 47. A fixing block 56 is fixed on the surface of the material box 21. The top of the mating rod 47 is inclined. When the electric push rod 22 is driven... When the output shaft drives the crossbar 24 to move to the right, the crossbar 24 can abut against the mating rod 47, pushing the mating 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 the push rod 46 to the right, and the push 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, so it 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 being loaded. At this time, the contact spring 51 is inserted into the insertion groove 55 on the right side of the mating rod 47, and the mating rod 47 and the contact spring 51 are engaged. The force pushing to the right causes the contact spring 51 to be squeezed downwards, thus pushing the mating rod 47 downwards. After the mating rod 47 moves downwards a certain distance, under the action of the spring 53, the locking rod 52 inserts into the locking groove 54 on the right side of the mating rod 47, limiting 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, thereby controlling the swing plate 42 to straighten the aluminum plate. This ensures that the straightening operation can only be performed after the aluminum plate has been placed, avoiding affecting the normal placement of the aluminum plate. When the U-shaped slide rod 45 moves to the left... After positioning, the locking rod 52 can be moved to the right by the fixing block 56, thereby exiting from the locking groove 54 on the right side of the mating rod 47, thus releasing the limitation 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 crossbar 24 to reset, the crossbar 24 abuts against the inclined surface at the top of the mating rod 47, pushing the mating rod 47 downward. This will not affect the movement of the crossbar 24 to the left side of the mating rod 47. When the mating rod 47 is no longer abutted, it can be reset under the action of the connecting spring 48, waiting for the next operation.

[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, the top of the bracket 7 is fixed with a hydraulic cylinder 8, 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 the top of the base 1 is fixed with a feeding guide plate 12. The inclined feeding guide plate 12 can assist in unloading. When the ejected plate 29 is tilted to unload, the workpiece can fall on the feeding guide plate 12 and slide down under its own gravity for collection.

[0039] During aluminum plate processing, aluminum plates are neatly stacked and placed into the material box 21 from the top. The electric push rod 22 is activated, controlling the push plate 23 to move to the right, thus pushing an aluminum plate to the right and onto the top of the mold body 6 via the material box 21. During this process, the output shaft of the electric push rod 22 drives the horizontal bar 24 to move together. The horizontal bar 24 pushes the vertical bar 26 downwards via the support rod 25. The vertical bar 26 moves the sliding plate 27 downwards, which in turn moves the connecting rod 28 and the ejector plate 29 downwards. The movement will not affect the normal placement of the new aluminum plate on the mold body 6. After the connecting rod 28 moves the ejector plate 29 downward a certain distance, the pull rope 34 can no longer pull the support plate 32. The support plate 32 can then reset under its own weight. At the same time, the L-shaped extrusion plate 36 is no longer in contact with the inner wall of the base 1. Under the action of the reset spring 37, the L-shaped extrusion plate 36 moves upward to extrude the ejector plate 29, causing the ejector plate 29 to rotate and reset again. This will not affect the normal retraction of the ejector plate 29 into the mold body 6.

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

[0041] When the connecting rod 28 moves the ejector plate 29 upward a certain 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 rotates upward at the position hinged with the groove 31. The support plate 32 can then lift the bottom of the workpiece, preventing 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 a certain distance, the L-shaped extrusion plate 36 is pressed against the inner wall of the base 1. The L-shaped extrusion plate 36 moves downward in a de facto manner on the connecting rod 28. The L-shaped extrusion plate 36 no longer presses against the ejector plate 29. Under the action of the auxiliary spring 38, the ejector plate 29 can swing towards the side closer to the L-shaped extrusion plate 36 at the position hinged with the connecting rod 28, thereby tilting the workpiece. The workpiece falls onto the unloading guide plate 12 and slides away for collection.

[0042] When the output shaft of the electric push rod 22 drives the crossbar 24 to move to the right, the crossbar 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 moves the push rod 46 to the right, and the push 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, thus not affecting 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 being loaded. At this time, the contact spring 51 is inserted into the insertion groove 55 on the right side of the mating rod 47. The mating rod 47 exerts a rightward pushing force on the contact spring 51, and the contact spring 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 spring 53, the locking rod 52 is inserted into the locking groove 54 on the right side of the mating rod 47, limiting the mating rod 47. At this time, under the action of tension spring 49, the U-shaped slide rod 45 can move to the left. The U-shaped slide rod 45 moves together 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 conjunction with the reset spring 43, the swing plate 42 can be controlled to swing back and forth, which can knock and vibrate the aluminum plate placed on the top of the mold body 6, ensuring that the aluminum plate can remain flat and avoiding the aluminum plate from being tilted when placed, which may cause the aluminum plate to tilt and get stuck, thus affecting the quality of the subsequent stamped products.

[0043] When the U-shaped slide bar 45 returns to its original position to the left, the locking bar 52 can be pushed to the right by the fixing block 56, thus exiting from the slot 54 on the right side of the mating bar 47, thereby releasing the limitation on the mating bar 47. Under the action of the connecting spring 48, the mating bar 47 moves upward to return to its original position. When the electric push rod 22 drives the crossbar 24 to return to its original position, the crossbar 24 abuts against the inclined surface at the top of the mating bar 47, pushing the mating bar 47 downward. This will not affect the movement of the crossbar 24 to the left side of the mating bar 47. When the mating bar 47 is no longer abutted, it can return to its original position under the action of the connecting spring 48, ready for the next operation.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
