Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a multi-specification irregular aluminum extrusion mold with interchangeable cavities. Background Technology

[0002] Aluminum, due to its lightweight, high strength, and corrosion resistance, is widely used in building profiles, transportation components, and electronic and electrical facilities. To obtain aluminum materials with different cross-sectional shapes, extrusion molding is typically used. This process applies high pressure to the aluminum raw material through a cavity structure in a mold, causing it to flow and form the desired irregular cross-section. Irregularly shaped aluminum materials are in high demand in engineering and product manufacturing, with different specifications and shapes corresponding to different mold cavities.

[0003] Existing dies for extruding irregularly shaped aluminum materials mostly consist of a die base and inserts, with specific cavities machined into the inserts. If a change in specifications or shape is required during production, the inserts must be disassembled and replaced. However, this usually necessitates manual shutdown to eject or pry the inserts out of the die base. This process is time-consuming and labor-intensive, impacting production cycle time and easily causing localized wear on the die. Due to the slow replacement speed, the cavities within the inserts cannot be switched in a timely manner, limiting continuous production and making it difficult to meet the demands for efficient processing of various specifications of irregularly shaped aluminum materials.

[0004] Therefore, a multi-specification aluminum extrusion die with interchangeable cavities is needed to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-specification irregular aluminum extrusion die with interchangeable cavities, so as to solve the problem mentioned in the background art that the cavities in the inserts are difficult to switch in a timely manner, which restricts continuous production and makes it difficult to meet the needs of efficient processing of multi-specification irregular aluminum materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-specification irregular aluminum extrusion mold with interchangeable cavities, comprising a base, a transmission seat fixed at the top of the base, a mold base rotatably connected to the top of the transmission seat, four sets of slots being opened in the mold base, each set of slots having two sets of through holes, a right cavity being opened on the left side of the base, a drive motor being fixedly connected in the right cavity, a swing arm being fixedly sleeved at the output end of the drive motor, a left slider being rotatably connected at the end of the swing arm, a rotating frame being slidably sleeved on the outside of the left slider, a right slider being rotatably connected on the right side of the rotating frame, a connecting rod being slidably sleeved on the outside of the right slider, a fixed plate being rotatably connected behind the connecting rod, a top rod being fixedly connected on the right side of the fixed plate, and the top rod penetrating upward through the transmission seat.

[0007] As a further technical solution of this utility model, the rotating frame is provided with a U-shaped groove machined along its length, and the left slider is embedded in the U-shaped groove and slides.

[0008] As a further technical solution of this utility model, the top end of the right cavity and the top and bottom ends of the transmission seat are all provided with slots for the movement of the push rod.

[0009] As a further technical solution of this utility model, each slot is equipped with an insert, and each set of inserts has a wing plate processed on its edge, the wing plate abutting against the surface of the mold base.

[0010] As a further technical solution of this utility model, the top rod is fixed with two sets on the right side of the fixing plate, which correspond to the two sets of through holes in the groove respectively.

[0011] As a further technical solution of this utility model, the mold base is a circular platform, and the inserts are distributed in a ring inside the mold base.

[0012] As a further technical solution of this utility model, a rotating seat is rotatably connected inside the transmission seat, a left cavity is opened on the right side of the base, a servo motor is fixedly connected inside the left cavity, a drive shaft is fixedly connected to the output end of the servo motor, and the left side of the drive shaft is connected to a gear reducer.

[0013] As a further technical solution of this utility model, the output end of the gear reducer extends toward the transmission seat and is fixedly connected to an output shaft. A drive gear is fixedly sleeved on the outside of the output shaft, and a transmission gear ring is fixedly sleeved on the outside of the rotating seat. The drive gear and the transmission gear ring are meshed and connected, and a baffle is covered on the outside of the drive gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a drive motor, a swing arm, a left slider, a transmission seat, a connecting rod, a right slider, a push rod, a slot, an insert, a wing plate, and a mold base, the swing arm can drive the left slider to slide under the drive motor, and then drive the right slider to move through the connecting rod, so that the push rod pushes the insert in the slot upward. When the insert is pushed to the surface of the mold base, the limiting effect of the wing plate makes it easy for the external clamp to quickly clamp and remove it, thereby realizing the automatic ejection and replacement of the insert, avoiding the impact of manual disassembly on efficiency, shortening the cavity replacement time, and ensuring the continuity and efficiency of the special-shaped aluminum extrusion production process.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a multi-specification aluminum extrusion mold with interchangeable cavities, comprising a base 9, a transmission seat 6 fixed to the top of the base 9, a mold base 1 rotatably connected to the top of the transmission seat 6, four sets of slots 2 opened in the mold base 1, each set of slots 2 having two sets of through holes 3, a right cavity 17 opened on the left side of the base 9, a drive motor 19 fixedly connected in the right cavity 17, the drive motor 19 being model SGM7J-04A7C, a swing arm 21 fixedly sleeved at the output end of the drive motor 19, a left slider 22 rotatably connected to the end of the swing arm 21, and the left slider 22 having an external... A rotating frame 20 is slidably connected. A right slider 24 is rotatably connected to the right side of the rotating frame 20. A connecting rod 23 is slidably connected to the outside of the right slider 24. A fixed plate 18 is rotatably connected to the rear of the connecting rod 23. A top rod 25 is fixedly connected to the right side of the fixed plate 18. The top rod 25 passes through the transmission seat 6 upward. A U-shaped groove is provided inside the rotating frame 20 along its length. The left slider 22 slides in the U-shaped groove. The top end of the right cavity 17 and the top and bottom ends of the transmission seat 6 are provided with slots for the top rod 25 to move. Two sets of top rods 25 are fixed on the right side of the fixed plate 18, corresponding to two sets of through holes 3 in the slot 2 respectively.

[0022] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the drive motor 19 drives the swing arm 21 to swing left and right. The end of the swing arm 21 engages with the left slider 22 through a rotating shaft, causing the left slider 22 to slide within the transmission seat 6. The left slider 22 drives the connecting rod 23 to transmit motion, pushing the right slider 24 to move left and right. The right slider 24 further drives the ejector rod 25 to move upward. When the ejector rod 25 contacts the bottom end of the insert 4 in the slot 2, it can eject the insert 4 from the slot 2. Since the insert 4 has a wing plate 5 on its edge, it can be clamped by an external fixture and quickly removed when it is ejected to the surface of the mold base 1. This solves the problem of having to stop the machine and manually disassemble the insert 4 for replacement, which is time-consuming and labor-intensive. It realizes the automatic ejection of the insert 4, greatly shortens the mold change time, and improves the production efficiency of shaped aluminum extrusion.

[0023] Each slot 2 contains an insert 4. Each set of inserts 4 has a wing plate 5 machined on its edge. The wing plate 5 abuts against the surface of the mold base 1. The mold base 1 is a circular platform. The inserts 4 are distributed in a ring inside the mold base 1.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the rotary table 15 is machined into a circular platform with four sets of slots 2 evenly distributed on it. Each set of slots 2 contains a set of inserts 4, and the four sets of inserts 4 are arranged in a ring. Each insert 4 has a wing plate 5 on its edge, which abuts against the surface of the mold base 1 to ensure that the insert 4 is stably stressed during the extrusion process. The four sets of inserts 4 are machined into cavities of different specifications, which can meet the forming requirements of four types of special-shaped aluminum materials. The mold base 1 rotates 90° each time under the action of the drive mechanism, which can switch the inserts 4 of different specifications for extrusion. One installation can take into account the forming of multiple special-shaped aluminum materials, which greatly reduces the number of molds to be prepared.

[0025] Rotary seat 15 is rotatably connected inside transmission seat 6. Left cavity 8 is opened on the right side of base 9. Servo motor 10 is fixedly connected inside left cavity 8. Servo motor 10 is model MHMD042G1U, with encoder feedback, suitable for intermittent rotation control. Drive shaft 11 is fixedly connected to the output end of servo motor 10. Drive shaft 11 is connected to gear reducer 12 on the left side. Gear reducer 12 is model SEWR57. Output end of gear reducer 12 extends to transmission seat 6 and is fixedly connected to output shaft 13. Drive gear 14 is fixedly sleeved on the outside of output shaft 13. Transmission gear ring 16 is fixedly sleeved on the outside of rotary seat 15. Drive gear 14 and transmission gear ring 16 are meshed. Baffle 7 is covered on the outside of drive gear 14.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the servo motor 10 drives the drive shaft 11 to rotate. The drive shaft 11 is connected to the gear reducer 12. The reduced power is transmitted to the drive gear 14 through the output shaft 13. The drive gear 14 meshes with the transmission gear ring 16, causing the transmission gear ring 16 to drive the die base 1 to rotate horizontally. Each rotation of 90° rotates the extruded aluminum material along with the insert 4 to the unloading position. At the same time, the new insert 4 automatically rotates into the extrusion station. In conjunction with external equipment such as the hydraulic press, a "extrusion-rotation-unloading" cycle is formed, realizing the precise step rotation of the die base 1, making the extrusion and unloading continuously connected, reducing manual operation, and improving the degree of automation and production stability.

[0027] Working principle: The mold base 1 is a circular platform with four sets of slots 2 evenly distributed on it. Each slot 2 contains an insert 4, which abuts against the surface of the mold base 1 via a wing plate 5. The four sets of inserts 4 are arranged in a ring and are processed into cavities of different specifications. This allows for the one-time assembly to meet the extrusion requirements of various irregular aluminum materials. A rotating seat 15 is rotatably connected inside the transmission base 6. A transmission gear ring 16 is fixedly sleeved on the outside of the rotating seat 15. The servo motor 10 on the right side of the base 9 drives the gear reducer 12 through the drive shaft 11. The output shaft 13 is fixedly connected to the drive gear 14, which meshes with the transmission gear ring 16, causing the transmission gear ring 16 to drive the mold base 1 to rotate precisely. Each 90° rotation rotates the processed insert 4 to the unloading position. Meanwhile, the new insert 4 is transferred to the extrusion station and continuously extruded in conjunction with the external hydraulic press. After the drive motor 19 starts, it drives the swing arm 21 to swing back and forth. The end of the swing arm 21 engages with the left slider 22. The left slider 22 slides linearly in the transmission seat 6 and drives the connecting rod 23 to transmit motion, causing the right slider 24 to move left and right. The right slider 24 further drives the push rod 25 to move upward. When the push rod 25 contacts the bottom of the insert 4 in the slot 2, it pushes the insert 4 out. The edge of the insert 4 is provided with a wing plate 5. When it is pushed to the surface of the mold base 1, it can be clamped and removed by the external fixture, thereby realizing the quick disassembly and replacement of the insert 4, forming a cycle of extrusion-rotation-unloading, thereby improving the efficiency and stability of the extrusion of irregular aluminum materials.
