[0027] Example:

[0028] Please see Figure 1-6 An automatic insertion device for injection molded inserts includes a three-axis slide rail 1, a fixed plate 2 mounted on the slide rail 1, a rotary motor 3 fixedly connected to the fixed plate 2, and the output end of the rotary motor 3 extending movably through to one side of the fixed plate 2. A rotating plate 4 is fixedly connected to the output end of the rotary motor 3, and the rotating plate 4 is located on one side of the fixed plate 2. A cylinder 5 is fixedly connected to one side of the rotating plate 4, and a transition block 6 is fixedly connected to the output end of the cylinder 5. Two clamping blocks 7 are slidably connected to one side of the rotating plate 4, and each clamping block 7 is hinged to the transition block 6 via a hinge shaft with a connecting rod 8. A fixed tube is fixedly connected to the output end of the cylinder 5. 9. An inner rod 10 is slidably inserted into the fixed tube 9. A spring 11 is installed inside the fixed tube 9 and the inner rod 10. A slider 12 is fixedly connected to the circumferential surface of the inner rod 10. A groove 13 is opened on the fixed tube 9, and the slider 12 is slidably connected in the groove 13. A sliding sleeve 14 is slidably connected to the circumferential surface of the fixed tube 9, and the slider 12 is fixedly connected to the inner circumferential wall of the sliding sleeve 14. A sliding opening 15 is opened on the rotating plate 4. A rolling shaft 16 is rotatably connected to the circumferential surface of the sliding sleeve 14, and the rolling shaft 16 moves through the sliding opening 15. An arc-shaped strip 17 is fixedly connected to one side end of the fixed plate 2, and the rolling shaft 16 is located inside the arc-shaped strip 17.

[0029] In this embodiment, when the insert is embedded into the injection molding machine mold, the three-axis slide rail 1 drives the fixed plate 2 to move, so that the two clamping blocks 7 correspond to the material picking position of the insert. The cylinder 5 controls the adapter block 6 and the fixed tube 9 to rise. The adapter block 6 drives the two clamping blocks 7 to slide on the rotating plate 4 through two connecting rods 8. The two clamping blocks 7 approach each other to clamp the insert, and the insert is stably below the inner rod 10. The arc-shaped strip 17 restricts the sliding sleeve 14 through the rolling shaft 16. The sliding sleeve 14 restricts the inner rod 10 through the slider 12. The elastic force of the spring 11 acts between the fixed tube 9 and the inner rod 10. The position of the inner rod 10 remains unchanged, and the inner rod 10 extends within the fixed tube 9. Then, the three-axis slide rail 1 drives the fixed plate 2 to move, causing the clamped insert to move into the injection molding machine mold. The rotary motor 3 controls the rotating plate 4 to rotate. During the rotation of the rotating plate 4, the rolling shaft 16 rotates along the inner side of the arc strip 17. As the arc strip 17 changes in curvature, the rolling shaft 16 gradually moves away. After the rotating plate 4 rotates 90°, the insert aligns with the injection mold's inlet. The three-axis slide rail 1 controls the fixed plate 2 to move and place the insert into the injection mold's inlet. After the insert enters the injection mold, cylinder 5 pushes the adapter block 6 and fixing tube 9. The adapter block 6, through two connecting rods 8, moves the two clamping blocks 7 away, releasing them from clamping the insert. Simultaneously, the fixing tube 9, through the elastic force of spring 11, maintains a certain strength in the inner rod 10, pushing the insert until it is fully inserted into the injection mold. During this process, the inner rod 10 pushes the insert, while the rolling shaft 16 slides within the slide opening 15. As the insert fully enters the injection mold, the rolling shaft 16 follows the movement of the inner rod 10 and contacts the inner wall of the arc-shaped strip 17. Finally, the injection molding machine... Injection molding fixes the insert into the molded plastic part. After the insert is injection molded, the three-axis slide rail 1 drives the fixing plate 2 to move again to the insert picking position. The rotary motor 3 controls the rotating plate 4 to rotate in the opposite direction to reset. The rotating plate 4 drives the rolling shaft 16 to rotate. The rolling shaft 16 drives the sliding sleeve 14 to slide on the surface of the fixing tube 9 along the arc of the arc strip 17. The sliding sleeve 14 drives the inner rod 10 to retract into the fixing tube 9 through the slider 12 and compresses the spring 11. After the rotating plate 4 completes the reset, all other parts also return to the initial state and can pick up the insert again and embed it into the injection molding machine mold.

[0030] Specifically, a protrusion 18 is fixedly connected to the rotating plate 4, and the adapter block 6 is slidably connected to the protrusion 18.

[0031] In this embodiment, the adapter block 6 slides on the protrusion 18 during the up-and-down movement, and the protrusion 18 keeps the adapter block 6 stable.

[0032] Specifically, two tracks 19 are fixedly connected to the rotating plate 4, and two clamping blocks 7 are slidably connected to the two tracks 19 respectively.

[0033] In this embodiment, the two clamping blocks 7 slide on the rotating plate 4 via two tracks 19, and the two tracks 19 ensure the stability of the movement of the two clamping blocks 7.

[0034] Specifically, each of the two clamping blocks 7 has a clamping groove 20 at one end that is close to each other, and both clamping grooves 20 are engraved with anti-slip texture.

[0035] In this embodiment, the two clamping grooves 20 and their internal anti-slip texture can increase friction and improve the clamping effect of the two clamping blocks 7 on the insert.

[0036] Specifically, a fixing post 21 is fixedly connected inside the fixing tube 9, and a spring 11 is sleeved on the circumferential surface of the fixing post 21.

[0037] In this embodiment, the spring 11 extends and retracts within the inner rod 10 and the fixed tube 9. The fixed column 21 is used to stabilize the extension and retraction direction of the spring 11 and prevent the spring 11 from tilting and affecting its use.

[0038] Working Principle: When inserting a plastic part, the fixed plate 2 is moved by the three-axis slide rail 1, aligning the two clamping blocks 7 with the insert. The cylinder 5 controls the adapter block 6 and the fixing tube 9 to move upward. The adapter block 6, through two connecting rods 8, moves the two clamping blocks 7 closer together to clamp the insert. The fixing tube 9 moves upward, causing the inner rod 10 to extend outward and align with the insert. Then, the three-axis slide rail 1 controls the fixed plate 2 to move, aligning the clamped insert with the injection mold. The rotary motor 3 controls the rotating plate 4 to rotate, aligning the insert with the mold's insertion point. The three-axis slide rail 1 moves the fixed plate 2 to insert the insert into the insertion point. The cylinder 5 pushes the adapter block 6 and the fixing tube 9. The adapter block 6, through two connecting rods 8, moves the two clamping blocks 7 away and opens. Under the elastic force of the spring 11, the fixing tube 9 maintains a certain strength to push the extended inner rod 10 towards the insert. This pushes the insert to the required depth within the injection mold. At this point, as the fixed tube 9 and inner rod 10 push the insert, the rolling shaft 16 follows the movement of the inner rod 10 and re-contacts the arc strip 17. The three-axis slide rail 1 drives the fixed plate 2 to move towards the insert's pick-up position. The rotary motor 3 drives the rotating plate 4 to rotate and reset. The rolling shaft 16, following the change in the curvature of the arc strip 17, drives the sliding sleeve 14 to slide on the surface of the fixed tube 9. The sliding sleeve 14 drives the slider 12 to slide within the slide groove 13, thereby causing the inner rod 10 to retract into the fixed tube 9. After the rotating plate 4 resets, the two clamping blocks 7, the fixed tube 9, and the inner rod 10 also reset. The two clamping blocks 7 re-align with the insert, picking up the insert and embedding it into the injection mold. The injection molding machine injects plastic into the mold, forming a complete product from the plastic part and the insert.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
