Description

Technical Field

[0001] This utility model relates to the field of aluminum profile extrusion die technology, specifically to an aluminum profile extrusion die with a positioning structure. Background Technology

[0002] In the field of aluminum profile production and processing, extrusion dies are key equipment that determines the quality and precision of aluminum profile products. Their structural stability and positioning accuracy directly affect the forming effect of aluminum profiles. As industrial manufacturing continues to increase its requirements for the precision of aluminum profiles, the positioning performance of dies has become a focus of industry attention. Currently, the upper and lower dies of existing aluminum profile extrusion dies are usually fixed by locating pins. However, this positioning method has significant drawbacks: the connection between the locating pin and the die is subjected to huge forces during the extrusion process for a long time, resulting in poor stability. During long-term use, gaps may appear at the connection of the locating pin due to wear, deformation and other factors, making it difficult to maintain accurate alignment between the upper and lower dies and causing relative displacement. This offset directly causes uneven stress on the aluminum profile during the extrusion process, resulting in defects such as dimensional deviations, surface depressions, and deformation in the finished aluminum profile, which seriously affects product quality. At the same time, mold offset may also accelerate the wear of the mold itself, shorten the mold's service life, increase the equipment maintenance costs and scrap rate of the production enterprise, and restrict the further improvement of aluminum profile production efficiency and product quality.

[0011] Preferably, the turntable has a limiting groove inside that matches the support plate and the locking block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Significantly improving positioning accuracy and stability, the coordinated action of the rotating plate, transmission plate, ejector rod, support plate, and clamping block enables precise positioning of the upper and lower molds. The precise threads on one side of the rotating plate are precisely connected to the transmission plate, and the outer dimensions of the clamping block are precisely matched with the internal limiting groove of the turntable, with minimal clearance. During the extrusion process, it can effectively prevent the molds from shifting or gapping due to excessive extrusion pressure, significantly reducing the probability of defects in finished aluminum profiles and ensuring the stability of product quality. It is easy to operate and precise to adjust. The bevel gear in the drive unit meshes perfectly with the inclined tooth groove of the rotating plate. The diamond-shaped groove at the top of the slot block allows the operator to apply torque to rotate the plate using a special tool, thereby driving the plate to rotate and achieve positioning adjustment. This design makes the mold installation and positioning operation more labor-saving and efficient, and can quickly complete the positioning and fixing of the upper and lower molds, improving work efficiency. The structure is reasonably designed and highly stable. The limiting block matches the internal limiting groove of the slot plate, and the clearance is controlled within a very small range to ensure accurate positioning during the rotation of the rotating plate. The two ends of the push rod are welded and fixed to the transmission plate and the support plate respectively, which is firm and enhances the stability and load-bearing capacity of the overall structure. It can adapt to the large force during the extrusion process and extend the service life of the mold. With a wide range of applications and high practicality, the upper and lower molds are two separate components, each composed of a mold body and a mold sleeve. This split structure makes it highly adaptable to extrusion scenarios of aluminum profiles of different specifications, facilitating mold replacement and combination according to actual needs, improving the versatility and flexibility of the molds, and reducing production costs.

[0016] Please see Figure 1-5 This utility model provides a technical solution for an aluminum profile extrusion die with a positioning structure: an aluminum profile extrusion die with a positioning structure includes an upper die 1 and a lower die 2. The lower die 2 is set on the back of the upper die 1. A turntable 3 is fixed to the outer wall of the upper die 1, and a groove plate 4 is fixed to the outer wall of the lower die 2. The inner wall of the cavity inside the groove plate 4 is smooth and flat, providing a smooth movement trajectory for the rotation and sliding of the rotating plate 5. The inside of the groove plate 4 forms a cavity, and the rotating plate 5 is rotatably connected inside the cavity. The outer wall of one side of the rotating plate 5 is machined with precise threads, achieving a precise threaded connection with the transmission plate 7. The toothed groove on the side away from the transmission plate 7 ensures perfect meshing with the bevel gear 11. The inner side of the rotating plate 5 is fixed with a limiting block 6, and the limiting block 6 is slidably connected to the groove plate 4. The outer dimensions of the limiting block 6 match the limiting groove inside the groove plate 4, and the fit clearance is controlled within a very small range, ensuring the positioning of the rotating plate 5 during rotation. A fixing part is provided on one side of the outer wall of the rotating plate 5, and a driving part is provided on the other side of the rotating plate 5. The upper mold 1 and the lower mold 2 are two separate parts, which are the mold body and the mold sleeve, respectively. A limiting groove is opened at the center of the internal cavity of the groove plate 4, and the limiting groove matches the limiting block 6.

[0017] The fixing components include a transmission plate 7, which is threaded to the outer wall of the rotating plate 5. A push rod 8 is fixed to the front surface of the transmission plate 7. The two ends of the push rod 8 are welded to the transmission plate 7 and the support plate 9, respectively. The support plate 9 is fixed to the front surface of the push rod 8. The back of the support plate 9 is firmly connected to the push rod 8. The shape of the front surface matches the shape of the limiting groove inside the rotating plate 3, ensuring close contact when it is engaged with the rotating plate 3, providing stable support and positioning. The back of the support plate 9 is symmetrically fixed with locking blocks 10 on both sides. The outer dimensions of the locking blocks 10 are precisely matched with the limiting groove inside the rotating plate 3, ensuring a firm engagement and preventing loosening or falling off during operation.

[0018] The driving component includes a bevel gear 11, which is rotatably connected inside the slot plate 4. The bevel gear 11 meshes perfectly with the tooth groove on the inclined surface of the rotating plate 5. A slot block 12 is fixed to the top of the bevel gear 11. The diamond-shaped groove at the top of the slot block 12 can be perfectly matched with a special operating tool, making it easy for the operator to apply torque to rotate. The diamond-shaped groove at the top of the slot block 12 makes it easy for the operator to rotate with a tool. The side of the rotating plate 5 away from the transmission plate 7 is an inclined edge, and the surface of the inclined edge is machined with tooth grooves that match the bevel gear 11. The interior of the turntable 3 has a limiting groove that matches the support plate 9 and the locking block 10.

[0019] Working Principle: When using an aluminum profile extrusion die with a positioning structure, the user first installs the upper die 1 and lower die 2 into the die sleeve when installing the die to the die holder. Then, the user aligns the protruding support plate 9 on the side wall of the lower die with the position of the limiting groove on the turntable 3 and inserts it. After insertion, the user rotates the turntable 3. During rotation, the turntable 3 moves on the outer wall of the support plate 9 and the locking block 10. After rotating to the corresponding position, the user inserts a tool into the slot 12 and rotates it. The rotation of the slot 12 drives the bevel gear 11 to rotate simultaneously. When the bevel gear 11 rotates, it meshes with the tooth groove on the inclined side of the rotating plate 5, causing the rotating plate 5 to rotate simultaneously inside the slot plate 4. During the process, the limiting block 6 can limit the movement. When the rotating plate 5 rotates, it drives the transmission plate 7 to pull inward. During the pulling process, the push rod 8 drives the support plate 9 and the locking block 10 to move simultaneously. When the locking block 10 moves, it inserts into the locking groove inside the turntable 3 to limit the movement. Then, the user can tighten the groove block 12. After the upper mold 1 and the lower mold 2 are positioned, they are placed inside the mold frame and installed with the aluminum profile extrusion equipment. During the extrusion process, the locking block 10, which is locked inside the turntable 3, and the push rod 8 can effectively limit the movement between the upper mold 1 and the lower mold 2. This effectively prevents the problem of excessive extrusion pressure during the extrusion process, which may cause the molds to shift or have gaps, resulting in defects in the finished aluminum profile.
