Description

Technical Field

[0001] This application relates to the field of stamping die technology, specifically to an aluminum profile stamping die. Background Technology

[0002] The basic principle of aluminum profile stamping is to place the aluminum profile on a stamping press through the action of a die. The aluminum material undergoes plastic deformation due to the shearing and extrusion forces in the die, and under a certain stamping pressure, parts of a predetermined shape and size are formed.

[0003] However, common mold bases are often fixed to the worktable with bolts, making it difficult to replace them. Also, after stamping, the mold cavity wears down, and the parts are easily stuck inside, making them difficult to remove. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an aluminum profile stamping die, which has advantages such as easy replacement and demolding, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an aluminum profile stamping die, comprising a base plate, a top plate above the base plate, a movable die fixedly connected to the bottom of the top plate, a die base in contact with the upper surface of the base plate, a die cavity formed on the upper surface of the die base, an L-shaped tube fixedly embedded inside the die cavity, a piston slidably connected to the top end of the L-shaped tube, a push rod fixedly connected to the upper surface of the piston, a push plate fixedly connected to the top end of the push rod, the upper surface of the push plate being at the same level as the inner bottom wall of the die cavity, and a compression spring installed between the upper surface of the piston and the inner wall of the top end of the L-shaped tube.

[0006] The above solution, employing a quick-fixing mechanism consisting of a fixed shaft, pressure block, worm gear, and bidirectional worm, enables rapid installation and disassembly of the mold base. This improvement significantly simplifies the mold base replacement process, reduces the use of bolts, thereby saving replacement time and labor, and improving production efficiency. The demolding mechanism, composed of an L-shaped tube, piston, push rod, and push plate inside the mold, allows the piston to move upwards via airflow from an external air pump after stamping, which in turn drives the push plate to eject the workpiece from the mold cavity. This design effectively solves the problem of parts easily getting stuck inside the mold cavity in traditional molds, reducing the risk of part damage and improving the convenience and efficiency of part removal.

[0007] Furthermore, two guide posts are fixedly connected to the upper surface of the base plate, and two guide sleeves are fixedly connected to the bottom of the top plate, with each guide sleeve slidably sleeved with the guide post adjacent to it.

[0008] The above scheme and settings can limit the downward movement of the moving mold and improve its stability.

[0009] Furthermore, a set of positioning rods arranged in a matrix are fixedly connected to the upper surface of the base plate, and the mold base is sleeved with each positioning rod.

[0010] The above solution, through the setting of positioning rods, can achieve the purpose of limiting the position of the mold base.

[0011] Furthermore, the bottom end of the L-shaped tube is fixedly connected to the output end of an external air pump.

[0012] The above scheme, through the installation of an air pump, can provide an air source for the movement of the piston.

[0013] Furthermore, a spring is fixedly connected between the bottom end of each guide post and the base plate, and each spring is sleeved with the guide post adjacent to it.

[0014] The above scheme and settings can provide power for the reset of the moving mold.

[0015] Furthermore, two sets of brackets are fixedly connected to the upper surface of the base plate. Each set of brackets is rotatably connected to a fixed shaft, and a pressure block is fixedly connected to the outer surface of each fixed shaft. Each pressure block is in contact with the mold base.

[0016] The above solution, through the setting of the pressure block, can achieve the purpose of quickly fixing the mold base, which can facilitate the user to quickly replace the mold base.

[0017] Furthermore, worm gears are fixedly connected to the front ends of both fixed shafts, and two extension blocks are fixedly connected to the front end of the base plate. A bidirectional worm is rotatably connected inside the two extension blocks, and the two worm gears are respectively meshed with the two ends of the bidirectional worm.

[0018] The above scheme and settings can achieve the purpose of self-locking of the pressure block and improve the stability of the fixation.

[0019] Furthermore, a handle is fixedly connected to one end of the bidirectional worm gear.

[0020] The above solution, with its handle, makes it easy for users to turn the worm gear.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This aluminum profile stamping die features a quick-fixing mechanism consisting of a fixed shaft, pressure block, worm gear, and double-direction worm, enabling rapid installation and disassembly of the die base. This improvement significantly simplifies the die base replacement process, reduces the use of bolts, and thus saves replacement time and labor, improving production efficiency. The internal demolding mechanism, composed of an L-shaped tube, piston, push rod, and push plate, allows the piston to move upwards via airflow from an external air pump after stamping, thereby driving the push plate to eject the workpiece from the die cavity. This design effectively solves the problem of parts easily getting stuck inside the die cavity in traditional dies, reducing the risk of part damage and improving the convenience and efficiency of part removal.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, an aluminum profile stamping die includes a base plate 1 and a top plate 2 above the base plate 1. Two guide pillars 11 are fixedly connected to the upper surface of the base plate 1, and two guide sleeves 12 are fixedly connected to the bottom of the top plate 2. Each guide sleeve 12 is slidably sleeved with the guide pillar 11 adjacent to it. Through the above arrangement, the downward movement of the moving die 3 can be limited, thereby improving the stability of movement. A spring 14 is fixedly connected between the bottom end of each guide pillar 11 and the base plate 1. Each spring 14 is sleeved with the guide pillar 11 adjacent to it. Through the above arrangement, the resetting of the moving die 3 can be provided with power.

[0031] Please see Figure 1 , Figure 3 and Figure 4 The bottom of the top plate 2 is fixedly connected to the moving mold 3. The upper surface of the bottom plate 1 is in contact with the mold base 4. The upper surface of the mold base 4 is provided with a mold cavity 5. An L-shaped tube 6 is fixedly embedded inside the mold cavity 5. A piston 7 is slidably connected to the top of the L-shaped tube 6. A push rod 8 is fixedly connected to the upper surface of the piston 7. A push plate 9 is fixedly connected to the top of the push rod 8. The upper surface of the push plate 9 is at the same level as the inner bottom wall of the mold cavity 5. A compression spring 10 is installed between the upper surface of the piston 7 and the inner wall of the top of the L-shaped tube 6. With the above settings, after the stamping is completed, the piston 7 can be pushed upward by the airflow output by the external air pump, thereby driving the push plate 9 to push out the workpiece, achieving the effect of easy demolding. The bottom end of the L-shaped tube 6 is fixedly connected to the output end of the external air pump. With the setting of the air pump, an air source can be provided for the movement of the piston 7.

[0032] Please see Figure 1 , Figure 2 and Figure 3 A set of matrix-arranged positioning rods 13 are fixedly connected to the upper surface of the base plate 1. The mold base 4 is sleeved with each positioning rod 13. The positioning rods 13 can limit the position of the mold base 4. Two sets of brackets 15 are fixedly connected to the upper surface of the base plate 1. Each set of brackets 15 has a fixed shaft 16 rotatably connected inside. Each fixed shaft 16 has a pressure block 17 fixedly connected to its outer surface. Each pressure block 17 is in contact with the mold base 4. The pressure block 17 can quickly fix the mold base 4, making it easy for the user to quickly replace the mold base 4.

[0033] Please see Figure 1 , Figure 2 and Figure 3Two fixed shafts 16 are fixedly connected to the front ends of worm gears 18, and two extension blocks 19 are fixedly connected to the front ends of the base plate 1. Two bidirectional worm gears 20 are rotatably connected inside the two extension blocks 19. The two worm gears 18 are respectively meshed with the two ends of the bidirectional worm gear 20. Through the above settings, the pressure block 17 can be self-locked, improving the fixing stability. One end of the bidirectional worm gear 20 is fixedly connected to a handle 21. The handle 21 makes it easy for the user to rotate the bidirectional worm gear 20.

[0034] In this embodiment, an aluminum profile stamping die employs a quick-fixing mechanism consisting of a fixed shaft 16, a pressure block 17, a worm gear 18, and a bidirectional worm 20. This mechanism enables rapid installation and disassembly of the die base 4, significantly simplifying the die base 4 replacement process, reducing the use of bolts, and thus saving replacement time and labor, while improving production efficiency. The demolding mechanism, composed of an L-shaped tube 6, a piston 7, a push rod 8, and a push plate 9 inside the die, allows the piston 7 to move upwards via airflow from an external air pump after stamping, thereby driving the push plate 9 to eject the workpiece from the die cavity 5. This design effectively solves the problem of parts easily getting stuck inside the die cavity 5 in traditional dies, reducing the risk of part damage and improving the convenience and efficiency of part removal.

[0035] The working principle of the above embodiment is as follows: When the mold is in a non-working state, the moving mold 3 on the top plate 2 is kept in a raised state under the action of the spring 14. The mold base 4 is fixed on the bottom plate 1 through the pressure block 17 and the worm gear 18 worm mechanism. The piston 7 in the L-shaped tube 6 is kept in a low position due to the action of the compression spring 10. The push plate 9 is flush with the inner bottom wall of the mold cavity 5. When the aluminum profile is placed in the mold cavity 5, the top plate 2 descends and drives the moving mold 3 to move towards the mold base 4, applying shearing and extrusion forces to cause the aluminum profile to undergo plastic deformation, forming parts of a predetermined shape and size. At this time, the spring 14 is compressed, and the guide post 11 and guide sleeve 12 ensure the stable movement of the moving mold 3. After the stamping is completed, the top plate 2 rises, the spring 14 releases energy to push the moving mold 3 to reset. At the same time, the external... The air pump starts, delivering airflow into the L-shaped tube 6, pushing the piston 7 to move upward against the resistance of the compression spring 10. The rise of the piston 7 drives the push rod 8 and the push plate 9 to move. The push plate 9 pushes the workpiece out of the mold cavity 5, avoiding the problem of the part getting stuck inside the mold cavity 5. At this time, the workpiece can be easily removed, ready for the next stamping. When it is necessary to replace the mold base 4, the user drives the bidirectional worm gear 20 to rotate by turning the handle 21. The meshing of the worm gear and the worm wheel 18 causes the fixed shaft 16 and the pressure block 17 to rotate, thereby releasing the fixation on the mold base 4. The mold base 4 can be easily removed from the positioning rod 13 and replaced with a new mold base 4. Then, turn the handle 21 again, and the pressure block 17 presses the mold base 4 again, realizing quick replacement and fixation.
