Description

Technical Field

[0001] This utility model relates to the field of injection molding auxiliary equipment, and in particular to an adaptive adjustment quick change device for injection molds. Background Technology

[0002] Injection molding machines are widely used in the production of plastic products. They inject molten plastic into a mold, which then cools to form the desired plastic product. Mold change is a common operation in injection molding, especially in the case of multi-variety, small-batch production. Traditional mold changeover processes typically require machine shutdown, disassembly of the old mold, installation of the new mold, and debugging. This process is time-consuming and significantly impacts production efficiency. Therefore, achieving rapid mold changeover has become an important issue in the development of injection molding machine technology.

[0003] In the prior art, Chinese Patent No. CN113954299A discloses a quick mold changing device and an injection molding machine for injection molding. This device achieves rapid mold changing through automated equipment. Specifically, the device uses components such as robotic arms and suction cups to automatically grasp, move, and position the mold, thereby reducing the time and error of manual operation and improving mold changing efficiency. This technology achieves automated mold changing to a certain extent and is suitable for some production scenarios.

[0004] The device still has some limitations, especially when handling large molds. The load-bearing capacity and stability of components such as the suction cups are insufficient, making it difficult to meet the needs of rapid mold changeover. In addition, the suction cups and other components are easily affected by the surface condition of the mold when moving it. For example, if the mold surface is uneven or has oil stains, the suction effect of the suction cups will be greatly reduced, leading to mold changeover failure or safety hazards.

Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example: An adaptive adjustment quick-change device for injection molds, such as... Figures 1-3 As shown, the system includes an injection molding machine 1, a mold 2, a support frame 3, a moving assembly, a movable plate 7, a hydraulic telescopic rod 8, an oil pump 9, a connecting block 10, a bolt rod 11, an electric slide rail 12, a first placement frame 13, a controller 14, and a second placement frame 15. The support frame 3 is located on the left side of the injection molding machine 1. A moving assembly is located at the bottom of the support frame 3 for moving the support frame 3. Electric slide rails 12 are located at both the left and right ends of the top of the support frame 3. A movable plate 7 is positioned between the two electric slide rails 12. The movable plate 7 connects to the electric slide rails 12. The sliding rail 12 is connected to a movable part. An oil pump 9 and a hydraulic telescopic rod 8 are mounted on the movable plate 7. The oil pump 9 and the hydraulic telescopic rod 8 are connected via a pipe. A connecting block 10 is connected to the bottom of the hydraulic telescopic rod 8, and a bolt 11 is slidably connected to the bottom of the connecting block 10. A first placement rack 13 is placed on the right side of the injection molding machine 1, and a second placement rack 15 is placed to the right of the first placement rack 13. The mold 2 is placed on the first placement rack 13. A controller 14 is mounted on the support frame 3, and the controller 14 is wiredly connected to the electric sliding rail 12 and the oil pump 9. When the mold 2 needs to be replaced, the old mold 2 is removed from the injection molding machine 1, and the new mold 2 is quickly installed in place by the device, ensuring continuous production. When the mold 2 needs to be gripped, the oil pump 9 pushes the hydraulic telescopic rod 8 downwards, the connecting block 10 engages with the hook of the mold 2, and the bolt 11 is inserted to secure it. When the oil pump 9 draws hydraulic oil, the hydraulic telescopic rod 8 pulls the mold 2 upward to complete the gripping and lifting of the mold 2. The electric slide rail 12 controls the horizontal movement of the movable plate 7 so that the hydraulic telescopic rod 8 can be accurately aligned with the hook position of the mold 2 to ensure the accuracy of the gripping of the mold 2.

[0022] like Figure 2As shown, the moving assembly includes a drive wheel 4, a motor 5, and casters 6. Three casters 6 and one drive wheel 4 are mounted on the bottom of the support frame 3. A motor 5 is also mounted on the bottom of the support frame 3, and the output shaft of the motor 5 is connected to the drive wheel 4. When the support frame 3 needs to be moved, the motor 5 is started via the controller 14. The output shaft of the motor 5 drives the drive wheel 4 to rotate, generating friction as the drive wheel 4 contacts the ground, thus propelling the support frame 3. Simultaneously, the three casters 6 at the bottom of the support frame 3 adjust their direction as the drive wheel 4 rotates, ensuring that the support frame 3 can flexibly turn and move along a predetermined path. After movement is complete, the casters 6 are locked to ensure that the support frame 3 remains stably in the target position.

[0023] like Figure 3 As shown, it also includes a positioning frame 16, a push plate 17, and an electric push rod 18. The electric push rod 18 is installed on the first placement frame 13, and the piston rod of the electric push rod 18 is connected to the push plate 17. The positioning frame 16 is connected to the first placement frame 13. After the mold 2 is placed on the first placement frame 13, the operator starts the electric push rod 18 through the controller 14. The piston rod of the electric push rod 18 pushes the push plate 17 forward. After the push plate 17 contacts the mold 2, it pushes the mold 2 to slide on the first placement frame 13. The push plate 17 pushes the mold 2 to the position of the positioning frame 16. The positioning frame 16 restricts the final position of the mold 2 to ensure the alignment accuracy between the mold 2 and the connecting block 10 and avoid deviation when the connecting block 10 descends.

[0024] like Figure 3 As shown, it also includes ball bearings 19. Several ball bearings 19 are laid in the middle part of the first placement frame 13, and the bottom of the mold 2 contacts the ball bearings 19. The rolling characteristics of the ball bearings 19 significantly reduce the friction between the mold 2 and the placement frame, so that the mold 2 can slide smoothly and steadily to the position of the positioning frame 16.

[0025] like Figure 3 As shown, it also includes identification cards 20, which are installed on both the first placement rack 13 and the second placement rack 15. Before changing the mold 2, the status of the mold 2 can be quickly confirmed by checking the identification cards 20 to avoid operational errors.

[0026] like Figure 1 As shown, it also includes a protective net 21. The support frame 3 and the second placement frame 15 are provided with protective nets 21 behind and to the left. When the staff is operating on the front side, the protective net 21 prevents the staff behind from accidentally entering the work area and avoids accidents. The design of the protective net 21 ensures the safety of the operation without affecting the normal operation of the staff.

[0027] like Figure 2As shown, it also includes a brush 22. The brush 22 is connected to the bottom of the support frame 3 and is located on the left and right sides of the drive wheel 4 and the caster wheel 6. When the support frame 3 moves, the brush 22 contacts the ground and cleans dust, debris and other impurities on the path. The cleaning function of the brush 22 ensures that the drive wheel 4 and the caster wheel 6 run smoothly and prevents impurities from getting stuck in the wheels or affecting the movement stability of the support frame 3.

[0028] When mold 2 needs to be replaced, the staff places the mold 2 to be replaced on the first placement rack 13 and records the status of mold 2 through the identification card 20. The electric push rod 18 is activated, and the push plate 17 pushes the mold 2 to slide on the ball bearing 19. The ball bearing 19 significantly reduces friction, allowing the mold 2 to move smoothly to the position of the positioning frame 16, ensuring the precise positioning of the mold 2. Subsequently, the controller 14 activates the oil pump 9, and the hydraulic telescopic rod 8 pushes the connecting block 10 downward. The connecting block 10 engages with the hook of the mold 2 and is fixed by inserting the bolt rod 11, ensuring that the mold 2 is stable and does not fall off during the movement. When the oil pump 9 draws hydraulic oil, the hydraulic telescopic rod 8 retracts upward, pulling the mold 2 up, completing the gripping and lifting of the mold 2. At the same time, the motor 5 drives the drive wheel 4 and the caster wheel 6 at the bottom of the support frame 3, so that the support frame 3 moves along the predetermined path to the top of the injection molding machine 1. During the movement, the brush 22 cleans the impurities on the path, ensuring that the support frame 3 moves smoothly. After reaching the target position, the hydraulic telescopic rod 8 controls the mold 2 to descend and be precisely installed into the injection molding machine 1, completing the replacement of the mold 2.

[0029] The combined design of the hydraulic telescopic rod 8 and connecting block 10 allows for adaptation to molds 2 of different sizes and weights, significantly improving the device's versatility. The protective net 21 isolates the work area, preventing personnel from accidentally entering and ensuring operational safety. The coordinated use of the ball bearing 19 and positioning frame 16 not only improves the positioning accuracy of the mold 2 but also reduces errors from manual adjustments. Furthermore, the brush 22 not only cleans impurities along the path but also further removes residues from the surface of the mold 2 during movement, enhancing the cleanliness of mold 2 replacements.
