[0002] The blow molding die clamping device is a core component used in the blow molding process to accurately close the die and apply sufficient pressure to ensure the die fits properly.

[0003] The actuator is driven by a power source (such as hydraulic, pneumatic or electric) to quickly connect the moving mold and the fixed mold and generate a stable clamping force to prevent molten material leakage during blow molding and ensure that the preform is formed into the required shape.

[0004] Traditional equipment requires the removal of multiple bolts when disassembling and replacing molds, resulting in prolonged downtime and reduced production line efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a blow molding die clamping device that can quickly switch bottle types.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a blow molding die clamping device that can quickly switch bottle types, including a clamping mechanism, the clamping mechanism being provided with a disassembly mechanism, the disassembly mechanism including four locking posts, a sliding plate fixedly connected above two adjacent locking posts, cylinders fixedly connected to the left and right sides above the sliding plate, springs fixedly connected to the left and right sides above the sliding plate around the outer positions of the two cylinders, a pull plate fixedly connected above two adjacent cylinders, and a handle fixedly connected to the side of the pull plate away from the cylinder.

[0007] Preferably, the clamping mechanism includes two clamping blocks, each with a square block fixedly connected to the center of its left and right sides. The two clamping blocks have square grooves on their opposite faces, and square slots are formed in the center of the inner wall of the square grooves. A first round hole is formed on the upper left and right sides of the inner wall of the square slot. A square sliding groove is formed on the upper upper side of the inner wall of two adjacent first round holes, and a second round hole is formed on the upper left and right sides of the inner wall of the square sliding groove.

[0008] Preferably, the inner wall of the first circular hole is slidably connected to the outer wall of the locking post, the inner wall of the square sliding groove is slidably connected to the outer wall of the sliding plate, the upper part of the inner wall of the square sliding groove is fixedly connected to the other end of the spring, and the inner wall of the second circular hole is slidably connected to the outer wall of the cylinder.

[0009] Preferably, a first blow molding die is slidably connected to the inner wall of the square groove. The first blow molding die includes two second blow molding dies. A square insert block is fixedly connected to the center of the side of each of the two second blow molding dies that are far apart. Circular insertion holes are opened on the left and right sides above the square insert block.

[0010] Preferably, the outer wall of the second blow molding die is slidably connected to the inner wall of the square groove, the outer wall of the square insert is slidably connected to the inner wall of the square slot, and the inner wall of the circular insertion hole is slidably connected to the outer wall of the locking post.

[0011] Preferably, a transmission mechanism is slidably connected to the inner wall of the left-side block. The transmission mechanism includes a bidirectional threaded rod and a round rod. A motor is fixedly connected to the rear of the bidirectional threaded rod. The outer wall of the round rod is slidably connected to the inner walls of the two left-side blocks, and the outer wall of the bidirectional threaded rod is threadedly connected to the inner walls of the two right-side blocks.

The inner right side of the two side plates is rotatably connected to the outer walls of the front and rear sides of the bidirectional threaded rod, and the left side of the two side plates is fixedly connected to the front and rear sides of the round rod.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a handle to pull a plate, which in turn moves a cylinder. The cylinder then moves a sliding plate and a locking post, causing the locking post to slide out of the circular insertion hole. The second blow molding die is then slid, causing it to slide and disengage from the square groove and slot, thus completing disassembly. For installation, simply pull the handle to place the locking post inside the first circular hole, then insert the square block into the square slot. Releasing the handle allows the spring to push the sliding plate, which in turn pushes the locking post to slide, inserting it into the circular insertion hole for fixation. This design allows for a single-action unlocking process by pulling the handle, significantly reducing operational steps and simplifying the process. This directly shortens the time required for mold changes, preventing production line efficiency losses due to prolonged downtime. It is particularly suitable for the production needs of multi-variety, small-batch bottle production. Attached Figure Description

[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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a blow molding die clamping device capable of quickly switching bottle types. (See also...) Figure 1-5A bottle-forming mold clamping device for quick bottle shape switching includes a clamping mechanism 2, which is equipped with a disassembly mechanism 1. The disassembly mechanism 1 includes four locking posts 11. A sliding plate 12 is fixedly connected above two adjacent locking posts 11. A cylinder 13 is fixedly connected to the left and right sides above the sliding plate 12. Springs 14 are fixedly connected to the left and right sides above the sliding plate 12 around the outer side of the two cylinders 13. A pull plate 15 is fixedly connected above two adjacent cylinders 13. A handle 16 is fixedly connected to the side of the pull plate 15 away from the cylinders 13. The clamping mechanism 2 includes two clamping blocks 21. A square block 22 is fixedly connected to the middle of the left and right sides of the clamping block 21. A square groove 23 is opened on the opposite side of the two clamping blocks 21. A square slot 24 is opened in the middle of the inner wall of the square groove 23. A first round hole 25 is opened on the left and right sides above the inner wall of the square slot 24. A first round hole 25 is opened on the left and right sides above the square slot 24. A square sliding groove 26 is provided on the upper part of the inner wall of the 5. Two round holes 27 are provided on the left and right sides of the upper part of the inner wall of the square sliding groove 26. The inner wall of the first round hole 25 is slidably connected to the outer wall of the locking post 11. The inner wall of the square sliding groove 26 is slidably connected to the outer wall of the sliding plate 12. The upper part of the inner wall of the square sliding groove 26 is fixedly connected to the other end of the spring 14. The inner wall of the second round hole 27 is slidably connected to the outer wall of the cylinder 13. A first blow molding mold 3 is slidably connected to the inner wall of the square groove 23. The first blow molding mold 3 includes two second blow molding molds 31. A square insert block 32 is fixedly connected to the middle of the side of the two second blow molding molds 31 that are far apart. A round insertion hole 33 is provided on the left and right sides above the square insert block 32. The outer wall of the second blow molding mold 31 is slidably connected to the inner wall of the square groove 23. The outer wall of the square insert block 32 is slidably connected to the inner wall of the square slot 24. The inner wall of the round insertion hole 33 is slidably connected to the outer wall of the locking post 11.

[0026] The disassembly mechanism 1 allows for quick disassembly and replacement of the No. 1 blow molding die 3. In use, firstly, the transmission mechanism 4 separates the two No. 1 blow molding dies 3 from the transmission mechanism 4. Then, by pulling the handle 16, the pull plate 15 drives the cylinder 13 to slide. The cylinder 13 drives the sliding plate 12 and the locking post 11 to slide. The locking post 11 slides out of the circular insertion hole 33. Then, the No. 2 blow molding die 31 is slid, causing the No. 2 blow molding die 31 and 32 to slide out of the square groove 23 and square slot 24, thus completing the disassembly. For installation, simply pull the handle 16 to place the locking post 11 in the correct position. Insert the square insert 32 into the square slot 24 inside the first round hole 25, then release the handle 16 so that the spring 14 pushes the sliding plate 12 to slide through the elastic force. The sliding plate 12 pushes the locking post 11 to slide, and the locking post 11 slides into the round hole 33 to fix it. The installation is then completed. This design can be unlocked with a single action by pulling the handle 16, which greatly reduces the number of operation steps. The simplified steps directly shorten the single mold change time and avoid the decline in production line efficiency caused by long downtime. It is especially suitable for the production needs of multi-variety, small-batch bottle types.

[0027] Reference Figure 6The outer wall of the second blow molding die 31 is slidably connected to the inner wall of the square groove 23. The outer wall of the square insert 32 is slidably connected to the inner wall of the square slot 24. The inner wall of the circular insertion hole 33 is slidably connected to the outer wall of the locking post 11. The outer wall of the bidirectional threaded rod 41 is rotatably connected to the first worktable 5. The first worktable 5 includes the second worktable 51. The front and rear sides of the second worktable 51 are fixedly connected to the side plates 52. The inner wall of the right side of the two side plates 52 is rotatably connected to the outer walls of the front and rear sides of the bidirectional threaded rod 41. The left side of the two side plates 52 is fixedly connected to the front and rear sides of the circular rod 42.

[0028] The output of motor 43 drives the bidirectional threaded rod 41 to rotate. The bidirectional threaded rod 41 rotates with the two blocks 22 on the right side, causing the two blocks 22 on the right side to move outward and simultaneously drive the two clamping blocks 21 and the second blow molding die 31 to move outward, thereby opening the mold.

[0029] Working principle: The disassembly mechanism 1 allows for quick disassembly and replacement of the No. 1 blow molding die 3. During use, the transmission mechanism 4 first separates the two No. 1 blow molding dies 3 from the transmission mechanism 4. Then, by pulling the handle 16, the pull plate 15 drives the cylinder 13 to slide. The cylinder 13 drives the sliding plate 12 and the locking post 11 to slide. The locking post 11 slides out of the circular insertion hole 33. Then, the No. 2 blow molding die 31 is slid, causing the No. 2 blow molding die 31 and 32 to slide out of the square groove 23 and square slot 24, thus completing the disassembly. For installation, simply pull the handle 16 to move the locking post 1... 1. Place the square insert 32 into the square slot 24 and insert it into the inner wall of the first round hole 25. Release the handle 16 so that the spring 14 pushes the sliding plate 12 to slide through the elastic force. The sliding plate 12 pushes the locking post 11 to slide. The locking post 11 slides into the round hole 33 to fix it, and the installation is completed. This design can be unlocked by pulling the handle 16 with a single action, which greatly reduces the operation steps. The simplified steps directly shorten the single mold change time and avoid the decline in production line efficiency caused by long downtime. It is especially suitable for the production needs of multi-variety, small-batch bottle types.

[0030] The output of motor 43 drives the bidirectional threaded rod 41 to rotate. The bidirectional threaded rod 41 rotates with the two blocks 22 on the right side, causing the two blocks 22 on the right side to move outward and simultaneously drive the two clamping blocks 21 and the second blow molding die 31 to move outward, thereby opening the mold.
