[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting the installation components, when installing the mold body, simply align the boss at the end of the mold body with the connecting groove on the mold base, and push the mold body to slide the boss into the connecting groove to achieve quick fixation between the mold body and the mold base. When disassembling, simply rotate the connecting ring to make the locking block exit from the locking groove and retract into the installation groove, and then pull the mold body outward to complete the disassembly. The entire installation and disassembly process does not require the use of additional tools, is simple and quick to operate, greatly shortens the mold change time, effectively improves production efficiency, and can better meet the needs of large-scale and high-efficiency production.

[0017] 2. In this utility model, the use of the installation component and the trigger component together ensures the stability of the connection between the mold body and the mold base. The locking block and the locking groove are compatible with each other. When the locking block is locked into the locking groove under the action of the spring force, a reliable mechanical connection can be formed, which effectively prevents the mold body from loosening or shifting during processing. At the same time, the elasticity of the spring allows the locking block to have a certain buffer space when subjected to a certain external force, which further enhances the stability of the connection.

[0023] 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.

[0024] Reference Figures 1-3This utility model provides an embodiment of a cold heading processing device with a quick mold changing structure, including a mold base 1, a mold body 2 mounted on the end of the mold base 1, an installation component 3 between the mold base 1 and the mold body 2, the installation component 3 including a connecting groove 31, a snap-fit ​​groove 32 evenly distributed inside the mold base 1, a boss 33 fixedly connected to the end of the mold body 2 near the mold base 1, an installation groove 34 evenly distributed inside the boss 33, a through groove 35 evenly distributed on the outer side of the boss 33, and springs 36 evenly distributed inside the boss 33. One end of each spring 36 is fixedly connected to a limiting block 37, and the end of each limiting block 37 away from the spring 36 is fixedly connected to a locking block 38. When installing the mold body 2, simply align the boss 33 at the end of the mold body 2 with the connecting groove 31 on the mold base 1, and push the mold body 2 to slide the boss 33 into the connecting groove 31. During the process of the boss 33 entering the connecting groove 31, the locking block 38, due to its rounded corner design, automatically retracts and compresses the spring 36 when it contacts the inner wall of the connecting groove 31. When the locking block 38 moves to the position corresponding to the locking groove 32, the spring 36... Releasing the elastic force pushes the locking block 38 into the locking groove 32, thus quickly fixing the mold body 2 to the mold base 1. For disassembly, simply rotate the connecting ring 394 to move the trigger ring 395. The trigger ring 395 applies pressure to the trigger block 391, causing the locking block 38 to exit from the locking groove 32 and retract into the mounting groove 34. Then, pulling the mold body 2 outward completes the disassembly. A trigger component 39 is provided on the outer side of the mold body 2. The connecting groove 31 is formed on the surface of the mold base 1 near the mold body 2, and the boss 33 is slidably connected to the connecting groove. Inside 31, the snap-fit ​​groove 32 and the snap-fit ​​block 38 are mutually adapted. The end of the snap-fit ​​block 38 away from the limiting block 37 is rounded. The mounting groove 34 and the through groove 35 are interconnected. The snap-fit ​​block 38 is slidably connected to the inside of the mounting groove 34 through the through groove 35. The end of the spring 36 away from the limiting block 37 is fixedly connected to the inner wall surface of the mounting groove 34. The limiting blocks 37 are slidably connected to the inside of the mounting groove 34. The number of snap-fit ​​grooves 32 and mounting grooves 34 is the same. The number of snap-fit ​​grooves 32, through grooves 35, springs 36, limiting blocks 37 and snap-fit ​​blocks 38 is the same.

[0025] Reference Figures 1-3The trigger component 39 includes a trigger block 391. Embedded grooves 392 are evenly distributed on the outer side of the mold body 2, providing more sliding space for the trigger block 391. A thread 393 is provided on the outer side of the mold body 2, and a connecting ring 394 is threadedly connected to it via the thread 393. The connecting ring 394 has a self-locking effect due to the constraint of the thread 393, preventing it from moving without external interference. A trigger ring 395 is fixedly connected to the end of the connecting ring 394. Anti-slip grooves 396 are evenly provided on the outer side of the ring 394. The trigger block 391 is fixedly connected to the outer side of the limiting block 37. The end of the trigger block 391 near the limiting block 37 is slidably connected to the inside of the mounting groove 34. The embedding groove 392 is connected to the mounting groove 34. The end of the trigger block 391 away from the limiting block 37 is slidably connected to the inside of the embedding groove 392. The end of the trigger block 391 near the trigger ring 395 is rounded. The trigger ring 395 has a conical structure. The inner wall of the trigger ring 395 abuts against the outer side of the trigger block 391.

[0026] Working principle: When the mold body 2 needs to be installed, align the boss 33 at the end of the mold body 2 with the connecting groove 31 on the mold base 1, and push the mold body 2 to slide the boss 33 into the connecting groove 31. During the process of the boss 33 entering the connecting groove 31, the locking block 38 in the mounting groove 34 inside the boss 33, because the end away from the limiting block 37 is rounded, will be squeezed when it comes into contact with the inner wall of the connecting groove 31, thus contracting into the mounting groove 34. The contraction of the locking block 38 causes the limiting block 37 to slide in the mounting groove 34 and compress the spring 36. As the boss 33 continues to go deeper into the connecting groove 31, when the locking block 38 moves to the position corresponding to the locking groove 32 inside the mold base 1, the compressed spring 36 is released. The spring force pushes the limiting block 37 to slide in the opposite direction in the mounting groove 34, thereby driving the locking block 38 to extend through the through groove 35 and lock into the locking groove 32, thus fixing the mold body 2 to the mold base 1. When it is necessary to disassemble the mold body 2, rotate the connecting ring 394, so that the connecting ring 394 drives the trigger ring 395 to move closer to the mold base 1. The trigger ring 395 applies pressure to the trigger block 391, and the trigger block 391 drives the limiting block 37 to slide in the mounting groove 34 and compress the spring 36. The limiting block 37 drives the locking block 38 to exit from the locking groove 32 and retract into the mounting groove 34. Then, pull the mold body 2 outward so that the boss 33 slides out from the connecting groove 31, thus completing the disassembly of the mold body 2.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
