Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a clamping device for injection molding shell processing. Background Technology

[0002] Clamping equipment for injection molding shell processing is a special device used to fix injection molds or workpieces. It uses mechanical structure, pneumatic or hydraulic power to drive the clamping components to move, which can stabilize the position of the workpiece during processing and ensure the molding accuracy and production efficiency of the injection molded shell.

[0003] Clamping equipment for injection molding shell processing drives the clamping components to move through a power source (such as mechanical transmission, pneumatic pressure, hydraulic pressure), and uses friction or mechanical locking structure to fix the mold or workpiece. During injection molding, it counteracts the injection pressure and keeps the workpiece in position, ensuring the stability of the processing.

[0004] In existing technologies, traditional clamping mechanisms often adopt single-end drive or asynchronous clamping designs, which can easily lead to asynchronous movement of the left and right grippers during the clamping process, resulting in workpiece positioning deviations. This cannot meet the high-precision processing requirements of medical devices, automotive parts, etc. Therefore, a clamping device for injection molding shell processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a clamping device for injection molding shell processing, which aims to improve the problem of workpiece positioning deviation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamping device for injection molded shell processing includes a carrier, a cylinder fixedly connected to the front side of the carrier, an active block fixedly connected to the driving end of the cylinder, driven rods rotatably connected to the left and right sides of the active block, fixed blocks fixedly connected to the inner walls of the left and right sides of the carrier, a connecting groove opened inside the fixed block, a connecting block slidably connected inside the connecting groove, springs fixedly connected to the far sides of the two connecting blocks, a support block fixedly connected to the top of the connecting block, a connecting rod rotatably connected to the near sides of the two support blocks, a driven platform rotatably connected to the bottom inner wall of the carrier, clamping plates fixedly connected to the near sides of the two support blocks, elastic pads fixedly connected to the near sides of the two clamping plates, and two adjustment components opened inside the clamping plates to facilitate adjustment according to different injection molded shell sizes.

[0008] As a further description of the above technical solution:

[0009] The adjustment component includes an adjustment groove, a placement block is slidably connected inside the adjustment groove, multiple positioning grooves are opened inside the clamping plate, and positioning pins are respectively provided on the upper and lower sides of the placement block.

[0010] As a further description of the above technical solution:

[0011] The placement block has a sliding connection to a connecting block inside, and the placement block has two screws connected to its internal thread. One of the connecting blocks has two grippers rotatably connected to its left side.

[0012] As a further description of the above technical solution:

[0013] The two driven rods are rotatably connected to the front sides of the two connecting blocks respectively, and the two springs are fixedly connected to the inner walls of the two connecting grooves respectively.

[0014] As a further description of the above technical solution:

[0015] The two connecting rods are rotatably connected to the outside of the driven platform on their adjacent sides. When the support block is moved by force, it moves synchronously through the connecting rods and the driven platform.

[0016] As a further description of the above technical solution:

[0017] The outer side of the locating pin contacts the inner wall of the locating groove, wherein the external threads of the two screws are connected to the inside of one of the connecting blocks;

[0018] As a further description of the above technical solution:

[0019] Remove the positioning pin and adjust the position of the placement block according to actual needs; remove the screw to release the limiting position of the connecting block.

[0020] As a further description of the above technical solution:

[0021] The top of the carrier is fixedly connected to a placement platform, and the two adjustment slots are formed on the outside of the clamping plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the active block is driven by a cylinder to slide, which in turn drives the driven rods on both sides to move synchronously, so that the connecting block slides inward synchronously in the connecting groove. The connecting block drives the connecting rod to rotate through the support block, which in turn pushes the driven table to rotate. The spring is compressed and stores energy, while the elastic pad on the clamping plate contacts the injection molded shell. The spring resets and pushes the connecting block to slide outward, causing the clamping plate to loosen, thereby realizing the synchronous clamping of the clamping plates on both sides. With the redundant synchronization mechanism of the driven table, the clamping force is evenly distributed. The buffer design of the elastic pad and the spring ensures rigid fixation and avoids damage to the injection molded shell.

[0024] 2. In this utility model, by removing the positioning pin, the placement block slides in the adjustment groove. The extension length is adjusted according to the size of the injection molded shell. After it is in place, the positioning pin is inserted and locked into the positioning groove for fixation. The connecting block is slid out of the placement block. After replacing the new clamping claw, it is fixed with screws. This realizes the flexible extension and retraction of the placement block, which can quickly adapt to the clamping requirements of injection molded shells of different sizes, significantly improve the versatility of the equipment, facilitate maintenance and replacement, and match diverse workpiece shapes.

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a clamping device for injection molding shell processing, including a carrier 1. The carrier 1 provides installation space and protection for the internal device. A cylinder 2 is fixedly connected to the front side of the carrier 1. The cylinder 2 is the power source for the clamping assembly. An active block 3 is fixedly connected to the drive end of the cylinder 2. The active block 3 can receive the force from the cylinder 2 and slide. A driven rod 4 is rotatably connected to the left and right sides of the active block 3. The driven rod 4 can move synchronously when the active block 3 slides. Fixed blocks 5 are fixedly connected to the inner walls of the left and right sides of the carrier 1. The fixed blocks 5 provide space for the opening of the connecting groove 6. The connecting groove 6 is opened inside the fixed blocks 5. The connecting groove 6 provides a limiting and guiding function for the connecting block 7. The connecting block 7 is slidably connected inside the connecting groove 6. The connecting block 7 can receive the force from the driven rod 4 and slide synchronously inward or outward.

[0033] Two connecting blocks 7 are fixedly connected to opposite sides with springs 8. Springs 8 have elasticity, providing elastic reset for the connecting blocks 7. After clamping, their own elastic reset drives the upper clamping assembly to reset. A support block 9 is fixedly connected to the top of the connecting blocks 7. When the support block 9 slides through the connecting blocks 7, it drives the connecting rod 10 to move synchronously. Connecting rods 10 are rotatably connected to adjacent sides of the two support blocks 9. When the connecting rods 10 are subjected to force, they can move synchronously through the driven platform 11. The bottom of the carrier 1... The inner wall is rotatably connected to a driven platform 11. When the connecting rods 10 on both sides are subjected to force, they can rotate synchronously through the driven platform 11, thereby playing an auxiliary rotation role. Clamping plates 12 are fixedly connected to the adjacent sides of the two support blocks 9 respectively. The clamping plates 12 can fix and clamp the injection molded shell. Elastic pads 13 are fixedly connected to the adjacent sides of the two clamping plates 12 respectively. The elastic pads 13 have an elastic function and can prevent the clamping plates 12 from directly contacting the injection molded shell rigidly. There are two adjustment components inside the clamping plates 12 that are easy to adjust according to different injection molded shell sizes.

[0034] Reference Figure 3 and Figure 4The adjustment assembly includes an adjustment groove 14, which provides limiting and guiding functions for the placement block 15. The placement block 15 is slidably connected inside the adjustment groove 14. The operator can adjust the extension and retraction of the placement block 15 according to actual needs to accommodate different injection molded shells. The clamping plate 12 has multiple positioning grooves 16 inside, which are used to cooperate with positioning pins 17 to limit and fix the placement block 15. Positioning pins 17 are respectively provided on the upper and lower sides of the placement block 15. When it is necessary to adjust the extension and retraction of the placement block 15, the positioning pins 17 are removed. The groove 16 allows it to extend and retract. When it moves to the appropriate position, the positioning pin 17 is inserted into the corresponding positioning groove 16 to complete the limiting and fixing. The internal part of the placement block 15 is slidably connected to the connecting block 18, and then the connecting block 18 is slid into the internal part of the placement block 15. The internal part of the placement block 15 is threaded with two screws 19, which limit and fix the connecting block 18. Two grippers 20 are rotatably connected to the left side of one of the connecting blocks 18, and then the grippers 20 can cooperate with the clamping plate 12 to complete the clamping and fixing of different injection molded shells.

[0035] Reference Figures 2 to 4 The two driven rods 4 are rotatably connected to the front of the two connecting blocks 7 at opposite ends. The connecting blocks 7 can move synchronously under the force from the driven rods 4. The two springs 8 are fixedly connected to the inner walls of the two connecting grooves 6 at opposite ends. The connecting grooves 6 provide fixation and support for the springs 8. The two connecting rods 10 are rotatably connected to the outside of the driven platform 11 at adjacent ends. The driven platform 11 can rotate under the force from the connecting rods 10, thereby playing an auxiliary role in synchronous linkage. Redundant synchronization can prevent a single driven rod 4 from being damaged and losing its function. When the support block 9 moves under force, it moves synchronously through the connecting rods 10 and the driven platform 11. The support block 9 can drive the driven platform 11 to rotate synchronously through the connecting rods 10, thus playing a role in synchronous movement.

[0036] The outer side of the positioning pin 17 contacts the inner wall of the positioning groove 16. The positioning pin 17 is used to lock into the interior of the corresponding positioning pin 17 to complete the limiting fixation. The outer threads of the two screws 19 are connected to the interior of one of the connecting blocks 18. The screws 19 can be screwed into the interior of the placement block 15 and the connecting block 18 to limit and fix the connecting block 18. Remove the positioning pin 17 and adjust the position of the placement block 15 according to actual needs. After removing the positioning pin 17, the placement block 15 can be slid and adjusted as needed. Remove the screws 19 to release the limiting of the connecting block 18. When it is necessary to release the limiting of the connecting block 18, the connecting block 18 can be disassembled by removing the screws 19 for replacement or maintenance. The top of the carrier 1 is fixedly connected to the placement platform 21, which is used to place the injection molded shell. The outer side of the two adjustment grooves 14 is opened inside the clamping plate 12, and the clamping plate 12 provides space for the adjustment grooves 14.

[0037] Working principle: When it is necessary to fix the injection molded shell, the cylinder 2 drives the active block 3 to slide, which in turn drives the driven rods 4 on both sides to move synchronously, so that the connecting block 7 slides inward synchronously in the connecting groove 6. The connecting block 7 drives the connecting rod 10 to rotate through the support block 9, which in turn pushes the driven platform 11 to rotate. The driven platform 11 plays a redundant synchronizing role, which in turn causes the clamping plates 12 on both sides to move synchronously towards the middle, thereby clamping and fixing the injection molded shell. At this time, the spring 8 is compressed and stores energy, and the elastic pad 13 on the clamping plate 12 contacts the injection molded shell to avoid deformation caused by rigid clamping. When the cylinder 2 is depressurized, the spring 8 returns to its original position and pushes the connecting block 7 to slide outward, causing the clamping plate 12 to loosen, completing the clamping cycle.

[0038] When it is necessary to adapt to injection molded shells of different sizes, the positioning pin 17 is removed, allowing the placement block 15 to slide within the adjustment groove 14. The extension length is adjusted according to the size of the injection molded shell. After it is in place, the positioning pin 17 is inserted and locked into the positioning groove 16 for fixation. If the clamp 20 needs to be replaced, the screw 19 is unscrewed to release the limit on the connecting block 18, and the connecting block 18 is slid out from the placement block 15. After replacing the new clamp 20, it is fixed by the screw 19. By adjusting the position of the placement block 15 and replacing the clamp 20, it can be adapted to injection molded shells of different specifications, achieving flexible adjustment of the clamping range.

[0039] 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.
