Description

Technical Field

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

[0002] Extrusion presses are the main equipment for producing tubes, bars, and profiles of light alloys (aluminum alloys, copper alloys, and magnesium alloys). Extrusion presses are mainly composed of mechanical, hydraulic, and electrical components.

[0003] When extruding aluminum, extrusion dies are required. However, with current technology, replacing extrusion dies, whether using a crane for hoisting or manual installation, requires manual adjustment of the die's position and angle within the installation cavity to ensure the extruded product meets specifications. The extrusion die itself is heavy and located inside the extruder's installation cavity, obstructing the operator's arm movement and limiting their ability to exert force. Therefore, adjusting the die's position and angle within the installation cavity is extremely laborious. Designing a die positioning structure for an aluminum extrusion press is a problem we need to solve. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mold positioning structure for an aluminum extrusion press.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a die positioning structure for an aluminum extrusion press, including an extrusion press base, an installation cavity fixedly installed on the top of the extrusion press base, a sealing plate fixedly installed on the top of the installation cavity, an extrusion die provided inside the installation cavity, an installation frame sleeved on the bottom of the extrusion die, and a positioning component fixedly installed inside the installation frame; and an installation assembly for fixing the positioned extrusion die, the installation assembly being connected to the extrusion die and the installation frame.

[0006] In the above technical solution, the mounting assembly further includes a connecting piece that is slidably connected inside the mounting frame, and a spring is fixedly mounted on one side of the connecting piece, the spring being fixedly mounted inside the mounting frame.

[0007] In the above technical solution, a turntable is rotatably connected to one side of the connecting piece, a gear ring is fixedly installed inside the turntable, multiple gears are meshed inside the gear ring, and fasteners are fixedly connected to the side of the multiple gears near the mounting bracket.

[0008] In the above technical solution, the fastener passes through the connecting piece and is inserted into the inside of the extrusion mold, a handle is fixedly connected to the outer wall of the turntable, and a first limiting block is fixedly connected to the side of the connecting piece near the turntable.

[0009] In the above technical solution, a second limiting block is fixedly connected to the side of the mounting frame near the turntable, and a rotating wheel is rotatably connected inside the mounting frame.

[0010] In the above technical solution, a sliding groove is further provided inside the mounting cavity, and the rotating wheel is disposed inside the sliding groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By setting up mounting brackets, positioning components, and installation assemblies, workers can position and initially fix the extrusion mold on the mounting bracket, and then install the extrusion mold together with the mounting bracket inside the installation cavity. This eliminates the need to adjust the position and angle of the extrusion mold inside the installation cavity, avoiding situations where workers cannot extend their arms or exert force to adjust the position and angle of the extrusion mold inside the installation cavity, thus facilitating the positioning and installation of the extrusion mold.

[0013] By setting up the installation components, multiple fasteners can be tightened simultaneously and quickly, making it convenient for workers to quickly secure the extrusion mold inside the installation cavity. This eliminates the need for workers to tighten each fastener individually inside the installation cavity, improving the efficiency of installing the extrusion mold and reducing the impact of different tightening forces on the mold's securing effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 The mold positioning structure of the aluminum extrusion press shown includes an extrusion press base 1, an installation cavity 2 fixedly installed on the top of the extrusion press base 1, a sealing plate 3 fixedly installed on the top of the installation cavity 2, an extrusion mold 4 inside the installation cavity 2, an installation frame 5 sleeved on the bottom of the extrusion mold 4, a positioning component 6 fixedly installed inside the installation frame 5, the positioning component 6 being adapted to the contour of the positioning groove on the outer circle of the extrusion mold 4; and an installation assembly, which is used to fix the positioned extrusion mold 4, and the installation assembly is connected to the extrusion mold 4 and the installation frame 5.

[0020] like Figures 2 to 3 As shown, the mounting assembly includes a connecting piece 7 slidably connected inside the mounting frame 5. A spring 8 is fixedly mounted on one side of the connecting piece 7, and the spring 8 is fixedly mounted inside the mounting frame 5. A turntable 9 is rotatably connected to one side of the connecting piece 7. A gear ring 10 is fixedly mounted inside the turntable 9, and multiple gears 11 mesh inside the gear ring 10. Fasteners 12 are fixedly connected to the side of each gear 11 near the mounting frame 5. The fasteners 12 pass through the connecting piece 7 and are inserted into the inside of the extrusion mold 4. A handle 13 is fixedly connected to the outer wall of the turntable 9. A first limiting block 14 is fixedly connected to the side of the connecting piece 7 near the turntable 9. The side of the mounting frame 5 near the turntable 9... A second limiting block 15 is fixedly connected to the side. By setting the first limiting block 14 and the second limiting block 15, the rotation distance of the turntable 9 and the handle 13 can be limited. The turntable 9 can drive the fastener 12 to fix the extrusion mold 4 inside the mounting cavity 2 with a specific torque through the toothed ring 10 and the gear 11. This avoids the situation where the torque of the fastener 12 is too large and damages the threads, or the torque is too small and affects the fastening effect, or the torques of multiple fasteners 12 are different, resulting in uneven force on the extrusion mold 4 and affecting the fastening effect. The mounting frame 5 is rotatably connected to a rotating wheel 16. The mounting cavity 2 is provided with a sliding groove 17, and the rotating wheel 16 is located inside the sliding groove 17.

[0021] Working principle: When the operator needs to install the extrusion mold 4, first pull the connecting piece 7, causing the connecting piece 7 to pull the spring 8 to extend and drive the turntable 9 and fastener 12 to move away from the top of the mounting frame 5. Then, the operator places the extrusion mold 4 on the mounting frame 5 and adjusts the position and angle of the extrusion mold 4 inside the mounting frame 5 so that the extrusion mold 4 is aligned with the positioning piece 6 inside the mounting frame 5. After the position and angle of the extrusion mold 4 are adjusted, the positioning piece 6 will insert into the positioning groove on the outer circle of the extrusion mold 4. The mounting hole on the extrusion mold 4 is aligned with the fastener 12, allowing the spring 8 to retract and drive the connecting piece 7 to reset, causing the connecting piece 7 to drive the turntable 9 and fastener 12 to reset, allowing the fastener 12 to be inserted into the mounting hole of the extrusion mold 4. Subsequently, the operator can lift the extrusion mold 4 through the mounting frame 5 and place it into the mounting cavity 2, so that the rotating wheel 16 at the bottom of the mounting frame 5 is placed into the slide groove 17. At this time, the operator can push the mounting frame 5, so that the mounting frame 5 slides along the inside of the slide groove 17 through the rotating wheel 16, thereby... The mounting frame 5 drives the initially positioned extrusion mold 4 into the interior of the mounting cavity 2 until the rotating wheel 16 slides to the end of the slide groove 17 and is blocked and stopped. At this time, the mounting frame 5 is installed inside the mounting cavity 2. The extrusion mold 4 on the mounting frame 5 will align with the position of the mounting cavity 2 and the extrusion cylinder. Since the position and angle of the extrusion mold 4 are adjusted on the mounting frame 5 before entering the mounting cavity 2, it is not necessary to adjust the position and angle of the extrusion mold 4 after the mounting frame 5 drives the extrusion mold 4 into the interior of the mounting cavity 2. This avoids the situation where the operator inside the mounting cavity 2 cannot extend their arm and cannot exert force to adjust the position and angle of the extrusion mold 4. It is convenient for the operator to position and install the extrusion mold 4. It should be noted that when the mounting frame 5 is placed into the interior of the mounting cavity 2, the position of the fastener 12 should be checked and adjusted to avoid the fastener 12 blocking the mounting frame 5 from entering the interior of the mounting cavity 2. It should also be noted that multiple operators need to work together to install and fix the extrusion mold 4 to avoid safety accidents.

[0022] Furthermore, when the mounting bracket 5 drives the extrusion die 4 into the mounting cavity 2 and aligns it with the extrusion cylinder, the fasteners 12 inside the mounting hole of the extrusion die 4 will be pressed against the threaded holes inside the mounting cavity 2 by the spring 8 through the connecting piece 7 and the turntable 9. At this time, the operator can push the turntable 9 to rotate through the protrusion on the turntable 9. First, rotate the handle 13 on the turntable 9 to contact the first limit block 14, and then rotate the turntable 9 in the opposite direction until the turntable 9 drives the handle 13 to contact the second limit block 15 and then stops. During this process, the turntable 9 will drive multiple gears 11 to rotate synchronously through the gear ring 10, so that the gears 11 drive the fasteners 12 to rotate accordingly, thereby causing multiple fasteners 12 to rotate at the same speed and enter the threaded holes inside the mounting cavity 2, so that the fasteners 12 fasten the extrusion die 4 and the mounting bracket 5 inside the mounting cavity 2, so that the part of the extrusion die 4 connected to the extrusion cylinder in the mounting cavity 2 is tightly fixed. This achieves the effect of quickly and simultaneously tightening multiple fasteners 12, making it convenient for workers to quickly secure the extrusion mold 4 inside the mounting cavity 2. It eliminates the need for workers to tighten each fastener 12 individually inside the mounting cavity 2, improving the efficiency of installing the extrusion mold 4 and reducing the impact of different tightening forces (torques) of multiple fasteners 12 on the tightening effect of the extrusion mold 4. Finally, the mounting plate 3 is fixed to the mounting cavity 2 for sealing, preventing external dust and impurities from entering. It should be noted that in the initial stage of reverse rotation of the turntable 9, since the fasteners 12 have just entered the threaded holes of the mounting cavity 2 and have not yet compressed the extrusion mold 4, workers can easily rotate the turntable 9. After rotating the turntable 9 to a certain angle in the reverse direction, and the fasteners 12 begin to compress the extrusion mold 4, workers need to use the handle 13 to rotate the turntable 9 to avoid situations where workers are unable to rotate the turntable 9.
