Description

Technical Field

[0001] This invention belongs to the field of aluminum extrusion dies, and specifically relates to an aluminum extrusion die that is easy to demold. Background Technology

[0002] Aluminum is a silvery-white, lightweight metal with ductility. Products made from aluminum and other alloying elements have good strength, wear resistance, weather resistance, and corrosion resistance. They are often used to make radiator parts or exterior decorative parts. In the production process of aluminum profiles, extrusion dies are used to shape the aluminum profiles.

[0003] Chinese Patent No. CN218109086U discloses an adjustable extrusion die, including an extrusion mechanism and an adjustment mechanism installed on one side of the extrusion mechanism. The adjustment mechanism is connected to the extrusion mechanism. The extrusion mechanism includes a base, an extrusion die installed on the base, several support columns, an upper die base installed on the support columns, an extrusion cylinder installed on the upper die base, and an extrusion column on which the extrusion cylinder is installed. The adjustment mechanism has an adjustment cylinder, one end of which is installed on the extrusion die. The operation of the adjustment cylinder can drive the extrusion die to slide in the base. The position of the extrusion die in the base can be adjusted by the adjustment cylinder, thereby changing the position of the extrusion groove below the extrusion column, and thus changing the shape of the extruded profile. The adjustment is convenient and quick, which not only speeds up the production rate but also saves some production costs. However, the aforementioned structure takes a long time to demold, causing interruptions in process connections, significantly reducing the continuous operation efficiency of the production line, and directly restricting the output per unit time. The aluminum profiles at high temperatures remain in the mold cavity for a long time, which can easily lead to profile deformation, surface scratches, or sticking to the mold due to uneven cooling. This seriously affects the dimensional accuracy and appearance quality of the product, increasing the defect rate. At the same time, the long-term contact between the mold and the high-temperature profile will aggravate mold cavity wear and oxidation, which not only increases the frequency and cost of mold cleaning and maintenance, but also shortens the overall service life of the mold. In addition, the low demolding efficiency extends the production cycle of a single batch of products, indirectly increasing the time cost and energy consumption per unit of product, weakening the company's competitive advantage in the market, and making it particularly difficult to adapt to the needs of large-scale and efficient aluminum profile production. Summary of the Invention

[0004] In view of the problems mentioned in the background art, the purpose of the present invention is to provide an aluminum extrusion die that is easy to demold, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: An aluminum extrusion die for easy demolding includes a die body, a demolding assembly at the lower end of the die body, and an installation assembly at the lower end of the die body. The demolding assembly includes a drive motor located at the lower end of the installation assembly. A drive groove is formed at the lower end of the die body, and a driving bevel gear is rotatably connected inside the drive groove. Driven bevel gears are rotatably connected to both sides of the drive groove, and the driving and driven bevel gears mesh with each other. Grooves are formed on both sides of the die body, and a drive screw is rotatably connected inside the groove. A drive bevel gear is fixedly connected to the outer surface of the drive screw. Connecting bevel gears are rotatably connected to the inner sides of the grooves, and the connecting bevel gears mesh with the drive bevel gears and are fixedly connected to the driven bevel gears. A telescopic rod is threadedly connected to the outer surface of the drive screw. Moving grooves are formed on both sides of the die body, and demolding rods are slidably connected inside the moving grooves. One end of the demolding rod is fixedly connected to the telescopic rod, and a demolding template is fixedly connected to the inner side of the demolding rod. The output shaft of the drive motor is inserted into the driving bevel gear.

[0006] As a preferred technical solution, the mounting assembly includes a mounting plate, the lower end of the mold body is located in the insertion slots on both sides of the drive slot, the inner side of each insertion slot is provided with a snap-fit ​​hole, the drive motor is fixedly connected to the outer side of the mounting plate, and insertion blocks are fixedly connected to both sides of the mounting plate, the insertion blocks and insertion slots are inserted into each other.

[0007] As a preferred technical solution, a square groove is provided on the outer side of each plug block, and a snap-fit ​​spring is fixedly connected inside the square groove. The other end of the snap-fit ​​spring is fixedly connected to a snap-fit ​​block, and the snap-fit ​​block and the snap-fit ​​hole snap into each other.

[0008] As a preferred technical solution, the inside of the square groove is provided with a sliding hole, a connecting rod is fixedly connected to the outside of the snap-fit ​​block, and an operating plate is fixedly connected to the other end of the connecting rod. The connecting rod and the sliding hole are slidably inserted into each other.

[0009] As a preferred technical solution, a sealing gasket is fixedly connected to the inner side of the mounting plate, and the sealing gasket wraps around the drive groove.

[0010] As a preferred technical solution, the output shaft of the drive motor is engaged with the outer side of the active bevel gear, the output shaft of the drive motor is fixedly connected to a connecting hexagonal locking pin, and the outer side of the active bevel gear is fixedly connected to a connecting hexagonal locking sleeve, the connecting hexagonal locking sleeve and the connecting hexagonal locking pin are engaged with each other.

[0011] As a preferred technical solution, the lower end of the demolding rod is slidably inserted into the upper end of the mold body, the lower end of the demolding rod is fixedly connected to a limiting post, and limiting holes are opened on both sides of the upper end of the mold body, with the limiting holes and limiting posts slidably inserted into each other.

[0012] In summary, the present invention has the following main beneficial effects: First, start the drive motor at the lower end of the installation component. Its output shaft is connected to the active bevel gear in the drive groove of the mold body, which drives the driven bevel gears on both sides to rotate synchronously. Through the meshing of the driven bevel gears with the bevel gears connected to the inner side of the groove, the drive screws on both sides of the mold body are driven to rotate. With the help of the threaded meshing of the drive screws and the telescopic rod, the rotational motion is converted into linear motion, which pushes the telescopic rod to drive the demolding rod in the moving groove to slide synchronously towards the cavity. Finally, the demolding platen inside the demolding rod applies a uniform pushing force to the formed aluminum profile, realizing rapid demolding. Through the multi-stage bevel gear linkage design, it is ensured that the demolding structures on both sides move synchronously and the demolding platen is subjected to balanced force, avoiding deformation and surface scratches caused by uneven force during demolding of the profile. This solves the problem of easy sticking of the mold in traditional demolding, reduces mold wear and maintenance costs, extends the service life of the mold, simplifies the operation process, and reduces the intensity of manual labor. Secondly, when installing the drive motor, align the plug-in blocks on both sides of the mounting plate with the plug-in slots at the bottom of the mold body and insert them. At this time, the snap-fit ​​spring in the square slot of the plug-in block will push the snap-fit ​​block to pop out, so that it accurately snaps into the snap-fit ​​hole on the inside of the plug-in slot, realizing the quick locking of the mounting plate and the mold body. At the same time, the output shaft of the drive motor will be inserted into the active bevel gear in the drive slot to complete the power connection. When it is necessary to disassemble the drive motor, simply press the operating plate on the outside of the mounting plate manually, drive the connecting rod to slide along the sliding hole in the square slot, pull the snap-fit ​​block to compress the snap-fit ​​spring and retract into the square slot, release the snap-fit ​​hole, and then the plug-in block can be pulled out from the plug-in slot to realize the quick separation of the drive motor and the mold body. The large mold body and the independent drive motor can be transported separately, reducing the volume and weight of a single component, reducing the space occupation and handling difficulty during transportation, and avoiding component damage caused by bumping during overall transportation.

[0019] Example

[0020] refer to Figures 1 to 5 This embodiment provides an aluminum extrusion die for easy demolding, comprising a die body 1, a demolding assembly 2 at the lower end of the die body 1, and an mounting assembly 3 at the lower end of the die body 1. The demolding assembly 2 includes a drive motor 21 disposed at the lower end of the mounting assembly 3. A drive groove 22 is formed at the lower end of the die body 1, and a drive bevel gear 23 is rotatably connected inside the drive groove 22. Driven bevel gears 24 are rotatably connected to both sides of the drive groove 22, and the drive bevel gears 23 and driven bevel gears 24 are meshed with each other. Grooves 213 are formed on both sides of the die body 1, and drive screws 27 are rotatably connected inside the grooves 213. A drive bevel gear 26 is fixedly connected to the outer surface of the moving screw 27. A connecting bevel gear 25 is rotatably connected to the inner side of the groove 213. The connecting bevel gear 25 meshes with the drive bevel gear 26. The connecting bevel gear 25 is fixedly connected to the driven bevel gear 24. A telescopic rod 28 is threadedly connected to the outer surface of the drive screw 27. Moving grooves 29 are opened on both sides of the interior of the mold body 1. A demolding rod 211 is slidably connected inside the moving groove 29. One end of the demolding rod 211 is fixedly connected to the telescopic rod 28. A demolding template 212 is fixedly connected to the inner side of the demolding rod 211. The output shaft of the drive motor 21 is inserted into the drive bevel gear 23.

[0021] refer to Figure 1 , Figure 4 and Figure 5The mounting assembly 3 includes a mounting plate 33. The lower end of the mold body 1 is located in the insertion slots 31 on both sides of the drive slot 22. Each insertion slot 31 has a snap-fit ​​hole 32 on its inner side. The drive motor 21 is fixedly connected to the outer side of the mounting plate 33. Each side of the mounting plate 33 is fixedly connected to an insertion block 34, which is inserted into the insertion slot 31. Each insertion block 34 has a square groove 35 on its outer side. A snap-fit ​​spring 36 is fixedly connected inside the square groove 35. The other end of the snap-fit ​​spring 36 is fixedly connected to a snap-fit ​​block 37. The snap-fit ​​block 37 and the snap-fit ​​hole 32 snap-fit ​​each other. When installing the drive motor 21, the plug-in blocks 34 on both sides of the mounting plate 33 are aligned with the plug-in groove 31 at the lower end of the mold body 1 and inserted. At this time, the snap-fit ​​spring 36 in the square groove 35 of the plug-in block 34 will push the snap-fit ​​block 37 to pop out, so that it accurately snaps into the snap-fit ​​hole 32 inside the plug-in groove 31, realizing the quick locking of the mounting plate 33 and the mold body 1. At the same time, the output shaft of the drive motor 21 will be inserted into the active bevel gear 23 in the drive groove 22 to complete the power connection.

[0022] refer to Figure 5 The square groove 35 has a sliding hole 38 inside. A connecting rod 39 is fixedly connected to the outside of the snap-fit ​​block 37. An operating plate 40 is fixedly connected to the other end of the connecting rod 39. The connecting rod 39 and the sliding hole 38 slide into each other. When it is necessary to disassemble the drive motor 21, simply press the operating plate 40 on the outside of the mounting plate 33 manually to drive the connecting rod 39 to slide along the sliding hole 38 in the square groove 35. This will pull the snap-fit ​​block 37 to compress the snap-fit ​​spring 36 and retract it into the square groove 35, releasing the snap-fit ​​with the snap-fit ​​hole 32. Then, the snap-fit ​​block 34 can be pulled out from the snap-fit ​​slot 31 to achieve rapid separation of the drive motor 21 from the mold body 1.

[0023] refer to Figure 4 A sealing gasket 6 is fixedly connected to the inner side of the mounting plate 33, and the sealing gasket 6 wraps the drive groove 22. The sealing gasket 6 fills the gap between the mounting plate 33 and the mold body 1 with its own elastic deformation characteristics, forming a closed protective space for the drive groove 22. It can effectively isolate aluminum chips, oil stains and cooling water vapor generated during the aluminum extrusion process, and prevent them from entering the drive groove 22 and adhering to the surface of transmission components such as the driving bevel gear 23 and the driven bevel gear 24, so as to prevent problems such as jamming, accelerated wear or corrosion at the gear meshing parts.

[0024] refer to Figure 2 and Figure 4The output shaft of the drive motor 21 is engaged with the outer side of the drive bevel gear 23. The output shaft of the drive motor 21 is fixedly connected to a connecting hexagonal locking pin 5, and the outer side of the drive bevel gear 23 is fixedly connected to a connecting hexagonal locking sleeve 4. The connecting hexagonal locking sleeve 4 and the connecting hexagonal locking pin 5 are engaged with each other. The connecting hexagonal locking pin 5 prefabricated at the output shaft end of the drive motor 21 forms a matching locking fit with the connecting hexagonal locking sleeve 4 on the outer side of the drive bevel gear 23. When installing the drive motor 21, the connecting hexagonal locking pin 5 is aligned with the connecting hexagonal locking sleeve 4 and inserted. By utilizing the anti-rotation characteristics of the hexagonal structure, rigid power transmission can be directly achieved.

[0025] refer to Figure 1 The lower end of the demolding rod 211 is slidably inserted into the upper end of the mold body 1. The lower end of the demolding rod 211 is fixedly connected to the limiting pin 7. Limiting holes 8 are opened on both sides of the upper end of the mold body 1. The limiting holes 8 and the limiting pin 7 are slidably inserted into each other. When the demolding assembly 2 drives the demolding rod 211 to slide along the moving groove 29 of the mold body 1, the limiting pin 7 at the lower end of the demolding rod 211 will be simultaneously embedded into the limiting hole 8 at the upper end of the mold body 1 and maintain a sliding fit. With the axial limiting effect of the limiting pin 7 and the limiting hole 8, the movement trajectory of the demolding rod 211 is precisely constrained, ensuring that the demolding rod 211 always slides smoothly in a straight direction, and avoiding the demolding rod 211 from deflecting, tilting or getting stuck during the process of pushing the profile.

[0026] Operating principle and advantages: During the assembly stage, the mounting plate 33 of the mounting component 3 is first fixed to the mold body 1. The plug-in blocks 34 on both sides of the mounting plate 33 are aligned with the plug-in slots 31 at the lower end of the mold body 1 and inserted. At this time, the snap-fit ​​spring 36 in the square slot 35 of the plug-in block 34 pushes the snap-fit ​​block 37 to pop out, so that it snaps into the snap-fit ​​hole 32 on the inner side of the plug-in slot 31, realizing the quick locking of the mounting plate 33 and the mold body 1. At the same time, the sealing gasket 6 on the inner side of the mounting plate 33 will completely wrap the drive groove 22 at the lower end of the mold body 1, forming a closed protective space to prevent aluminum chips and oil stains from entering the drive groove 22. Meanwhile, the connecting hexagonal pin 5 at the output shaft end of the drive motor 21 will be accurately inserted into the connecting hexagonal pin 4 on the outer side of the active bevel gear 23 to complete the pre-fixation of the power connection. When aluminum profile extrusion molding requires demolding, the drive motor 21 is started. The rotational torque of its output shaft is transmitted to the driving bevel gear 23 in the drive groove 22 through the engagement of the connecting hexagonal pin 5 and the connecting hexagonal sleeve 4. This drives the driven bevel gears 24 on both sides to rotate synchronously. The driven bevel gears 24 drive the driving bevel gears 26 and the driving screw 27 in the grooves 213 on both sides of the mold body 1 to rotate through the fixedly connected connecting bevel gears 25. The rotational motion is converted into linear motion by the threaded engagement of the driving screw 27 and the telescopic rod 28. This pushes the telescopic rod 28 to move the demolding rod 211 in the moving groove 29 towards the cavity. During this process, the limiting pin 7 at the lower end of the demolding rod 211 moves along the upper end of the mold body 1. The limiting insertion hole 8 slides smoothly, forming a precise guide for the movement trajectory of the demolding rod 211, preventing the demolding rod 211 from deviating or tilting. Finally, the demolding template 212 on the inner side of the demolding rod 211 applies a uniform pushing force to the formed aluminum profile, achieving fast and smooth demolding. If the drive motor 21 needs to be disassembled for maintenance or the mold needs to be transported, simply press the operating plate 40 on the outside of the mounting plate 33 manually to drive the connecting rod 39 to slide along the sliding hole 38 of the square groove 35, pull the locking block 37 to compress the locking spring 36 and retract it into the square groove 35. After the locking is released, the insertion block 34 can be pulled out from the insertion slot 31. At the same time, the connecting hexagonal locking post 5 and the connecting hexagonal locking cylinder 4 are separated, completing the rapid separation of the drive motor 21 and the mold body 1.
