[0020] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0021] This utility model provides a hydraulic linkage locking device for quick mold change. Please refer to [reference needed]. Figures 1-5 As shown, the system includes a base 1, with hydraulic linkage locking mechanisms 2 on both sides of the top of the base 1. The hydraulic linkage locking mechanism 2 includes a hydraulic cylinder 21 fixedly installed on the top of the base 1. A movable plate 22 is fixedly connected to one end of the piston rod of the hydraulic cylinder 21. A quick-release assembly 25 is provided on one side of the movable plate 22, and an L-shaped locking chuck 26 is provided on one side of the quick-release assembly 25. The movable plate 22 and the L-shaped locking chuck 26 can be quickly disassembled and assembled through the quick-release assembly 25.

An installation plate 3 is provided on the top of the base 1. A mold 4 is provided on the top of the installation plate 3. A positioning assembly is provided between the installation plate 3 and the mold 4. The positioning assembly includes a positioning pin 5 fixedly connected to the bottom of the mold 4, and a positioning hole 6 on the top of the installation plate 3 that is compatible with the positioning pin 5. Mounting blocks 7 are fixedly connected to both sides of the mounting plate 3. The top of the mounting block 7 is provided with fixing screws 8, and the mounting block 7 is locked to the base 1 by fixing screws 8.

[0022] In use, the base 1 is first fixed on the worktable of the mold processing equipment, ensuring that the base 1 is level and stable. Buffer pads are provided on the sides of the two L-shaped locking clamps 26 that are close to each other, ensuring that the mold 4 is clamped while minimizing damage. The sliding block 24 slides horizontally along the sliding groove 23, making the horizontal movement of the moving plate 22 more stable. When the mold 4 needs to be replaced, the hydraulic cylinder 21 is activated. The piston rod of the hydraulic cylinder 21 retracts, causing the two moving plates 22 to move relative to each other to the sides, thereby driving the two L-shaped locking clamps 26 to move relative to each other to the sides and disengage from the mold 4, thus unlocking it. At this time, the old mold 4 is removed from... Remove the mounting plate 3, place the new mold 4, align the positioning pin 5 with the positioning hole 6 and insert it to complete the initial positioning. Then, extend the piston rod of the hydraulic cylinder 21 to push the moving plate 22 to move towards the center, thereby causing the L-shaped locking chuck 26 to fit tightly with the edge of the mold 4. The two L-shaped locking chucks 26 clamp and fix the two sides of the mold 4 to achieve locking. During the locking process, the positioning component ensures that the mold 4 will not shift, ensuring the installation accuracy of the mold 4. The fixed screws 8 make it easy to replace the mounting plate 3 with one that matches the shape and size of the mold 4, so that the positioning pin 5 matches the positioning hole 6, making it convenient to use.

[0023] Furthermore, the quick-release assembly 25 includes a fixing block 251 fixed on the movable plate 22 and an insert block 252 fixed on the L-shaped locking clamp 26. A slot 254 adapted to the insert block 252 is provided on one side of the fixing block 251, and an L-shaped slide groove 253 is provided on the top of the fixing block 251. A press-fit assembly is provided in the L-shaped slide groove 253. The press-fit assembly includes a guide rod 255 fixedly connected in an L-shaped groove 253. A spring 256 is sleeved in the middle of the guide rod 255. Both ends of the guide rod 255 are movably sleeved with L-shaped sliders 257. Locking holes 259 are fixedly connected to the sides of the two L-shaped sliders 257 that are far apart from each other. The press-fit assembly also includes a locking groove 258 opened on one side of the insert block 252 and slidably connected to the L-shaped sliders 257. Locking rods 2591 that are adapted to the locking holes 259 are fixedly connected to both sides of the locking groove 258.

[0024] In use, when it is necessary to change the mold 4 according to different shapes and sizes, and to change the locking chuck to match it, by pressing the L-shaped slider 257, the two L-shaped sliders 257 slide along the L-shaped groove 253 towards the middle, compressing the spring 256, thereby driving the two locking holes 259 to disengage from the locking rod 2591. After releasing the lock on the insert block 252, the L-shaped locking chuck 26 can be pulled out. During installation, simply align the insert block 252 with the slot 254 and insert it, then release the L-shaped slider 257. 57. Under the rebound force of the spring 256, the two L-shaped sliders 257 will move relative to each other along the L-shaped groove 253, thereby moving the two locking holes 259 relative to each other to insert into the locking rod 2591, thus completing the installation. The operation is convenient and allows for quick assembly and disassembly of the L-shaped locking chuck 26. Different specifications of chucks, such as L-shaped, arc-shaped, and claw-shaped, can be replaced according to the specific shape and size of the mold 4 to ensure a tight fit with the mold 4 and achieve the best locking effect. It has strong versatility.

[0025] The working principle of this utility model is as follows: When it is necessary to replace the mold 4, the hydraulic cylinder 21 is activated. The piston rod of the hydraulic cylinder 21 retracts, causing the two moving plates 22 to move to the sides relative to each other. This, in turn, drives the two L-shaped locking clamps 26 to move to the sides relative to each other and disengage from the mold 4, thus unlocking it. At this time, the old mold 4 is removed from the mounting plate 3, and the new mold 4 is placed on it. The positioning pin 5 is aligned with the positioning hole 6 and inserted to complete the initial positioning. Then, the piston rod of the hydraulic cylinder 21 extends, pushing the moving plates 22 to move towards the center, thereby causing the L-shaped locking clamps 26 to fit tightly with the edge of the mold 4. The two L-shaped locking clamps 26 clamp and fix the two sides of the mold 4 to achieve locking. During the locking process, the positioning component ensures that the mold 4 will not shift, ensuring the installation accuracy of the mold 4. When it is necessary to replace the mold 4 with a different shape, size, and specifications, and when it is necessary to replace the locking chuck that is compatible with it, the mounting plate 3 must first be removed and replaced with a mounting plate 3 that is compatible with the mold 4. After fixing and installing it, by pressing the L-shaped slider 257, the two L-shaped sliders 257 slide along the L-shaped groove 253 towards the middle to compress the spring 256, thereby driving the two locking holes 259 to disengage from the locking rod 2591. After releasing the lock on the insert block 252, the L-shaped locking chuck 26 can be pulled out. During installation, simply align the insert block 252 with the slot 254 and insert it. Then, release the L-shaped slider 257. Under the rebound force of the spring 256, the two L-shaped sliders 257 will move towards each other along the L-shaped groove 253, thereby driving the two locking holes 259 to move towards each other and insert into the locking rod 2591, thus completing the installation.
