[0013] 1. This extrusion die and die sleeve separation device, through its separation mechanism, allows for efficient separation of the die and die sleeve. First, the die sleeve is placed on top of the support body, contacting the right side of the backing plate. Once placed, a servo motor drives a limit frame connected to the outer thread of a bidirectional threaded rod to move. This limit frame moves to the outer edge of the die sleeve and limits its movement. Simultaneously, the inner side of the limit frame contacts the right side of the die sleeve, stabilizing the die sleeve. A jack then precisely and powerfully pushes the ejector block, which slides within the die sleeve to smoothly eject the die body from it. This achieves efficient separation, reduces labor intensity, is easy to operate, has low cost, and high practicality. It significantly protects the die from damage, improves work quality, efficiency, and inherent safety, and shortens the time required for die separation.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model provides a technical solution: a separation device for extrusion die and die sleeve, including a support body 1, a separation mechanism 2 provided on the top of the support body 1, and a storage mechanism 3 provided on the right side of the top of the support body 1;

[0028] The separation mechanism 2 includes a back plate 21, which is fixedly connected to the top of the support body 1. A mold outer sleeve 22 is provided on the right side of the back plate 21. A mold body 23 is slidably connected inside the mold outer sleeve 22. A fixing frame 25 is fixedly connected to the left side of the back plate 21. A jack 26 is fixedly connected to the inside of the fixing frame 25. A top block 27 is fixedly connected to the right side of the jack 26. The top block 27 is slidably connected inside the mold outer sleeve 22. A fixing frame 24 is fixedly connected to the top of the back plate 21. A servo motor 28 is fixedly connected to the front side of the fixing frame 24. A bidirectional threaded rod 29 is fixedly connected to the rear side of the servo motor 28. A limit frame 291 is threadedly connected to the periphery of the bidirectional threaded rod 29. The limit frame 291 is slidably connected to the periphery of the mold outer sleeve 22.

[0029] The top block 27 passes through the inside of the back plate 21. The back plate 21 and the mold outer sleeve 22 are respectively provided with moving grooves, and the two moving grooves correspond to each other. The top block 27 is slidably connected in the moving groove, so that the mold body 23 can be ejected from the mold outer sleeve 22 under the action of the top block 27, realizing automatic separation. The rear side of the bidirectional threaded rod 29 is rotatably connected to the fixed frame 24. The inner side of the limiting frame 291 is in contact with the right side of the mold outer sleeve 22. The inner side of the limiting frame 291 is provided with a wear-resistant pad, so that the limiting frame 291 can limit the mold outer sleeve 22 under the action of the limiting frame 291, ensuring the stability of the mold outer sleeve 22 when the mold is ejected from the mold outer sleeve 22.

[0030] The left side of the mold jacket 22 is in contact with the right side of the backing plate 21, and the bottom of the mold jacket 22 is in contact with the top of the support body 1, so that the backing plate 21 can limit the mold jacket 22.

[0031] Example 2

[0032] Please see Figure 1-6 Furthermore, based on Embodiment 1, the storage mechanism 3 further includes a movable seat 33, which is slidably connected to the inside of the support body 1. A mold receiving box 31 is fixedly connected to the top of the movable seat 33, and lifting rings 32 are fixedly connected to the front and rear sides of the mold receiving box 31. An L-shaped frame 34 is fixedly connected to the front side of the movable seat 33, and the L-shaped frame 34 is slidably connected to the inside of the support body 1. A limit shaft 35 is threadedly connected inside the L-shaped frame 34. A sliding groove is opened inside the support body 1, and the movable seat 33 is slidably connected to the sliding groove, which facilitates the stability of the movable seat 33 under the action of the sliding groove.

[0033] A limiting groove is provided inside the bracket body 1. The L-shaped frame 34 is slidably connected in the limiting groove.

[0034] In actual operation, when this device is used and it is necessary to separate the mold from the mold sleeve, first place the mold sleeve 22 on the top of the support body 1 and make it contact the right side of the backing plate 21. After placement, the servo motor 28 can drive the limiting frame 291 connected to the outer thread of the bidirectional threaded rod 29 to move, so that the limiting frame 291 moves to the outer side of the mold sleeve 22 to limit it. At the same time, the inner side of the limiting frame 291 contacts the right side of the mold sleeve 22, so that the mold sleeve 22 is in a stable state and the mold sleeve 22 always maintains a stable position, avoiding separation failure or damage to the mold due to displacement.

[0035] Meanwhile, the movable seat 33 can slide flexibly in the groove inside the bracket body 1, moving the mold receiving box 31 to the right side of the mold outer sleeve 22 to receive the separated mold. When the movable seat 33 moves, it will drive the L-shaped frame 34 to move. When it moves to the designated position, the L-shaped frame slides and engages with the limiting groove inside the bracket body 1, and the limiting shaft 35 can fix the L-shaped frame firmly on the bracket body 1, so that the mold receiving box 31 can remain stable when receiving the mold, preventing the mold receiving box 31 from sliding accidentally and ensuring the safety of the mold storage process.

[0036] At this point, jack 26 can be activated. Jack 26 can precisely and powerfully push the ejector block 27. By using the sliding of ejector block 27 within the mold outer sleeve 22, the mold body 23 is smoothly ejected from the mold outer sleeve 22, allowing the mold body 23 to move into the mold receiving box 31. This achieves efficient separation, reduces the labor intensity of personnel, is convenient and easy to operate, has low cost and high practicality, and has significant effects in protecting the mold from damage, improving work quality, work efficiency and inherent safety level, and shortening the time required for mold separation.

[0037] The lifting ring 32 on the mold receiving box 31 facilitates the transfer of the mold using external lifting equipment, further improving the convenience of mold storage and handling.
