[0001] The present invention relates to the technical field of injection molding equipment, in particular to a mold core batch pin insertion mechanism. Background Art

[0002] During the injection molding process, it is often necessary to insert pins into mold cores. Different products use mold cores of varying sizes, and the positions of the pins can vary significantly. Existing mold core insertion mechanisms are mostly designed to operate only for mold cores of specific sizes and fixed pin positions. When the mold core needs to be replaced, the entire insertion mechanism often requires extensive adjustments or even replacement of parts, which not only increases production costs but also reduces production efficiency. Therefore, developing a mold core batch insertion mechanism that can adapt to pin installation positions for different mold core sizes and flexibly adjust the lateral movement and descent of the clamping arm is of great practical significance.

[0019] A needle tray 100 is provided on one side of the pin support 3 of the present invention, and a screening device 200 for aligning the pins is provided inside the needle tray 100.

[0020] The rotating swing arm assembly 4 of the present invention includes a forward and reverse motor 401 arranged on the pin bracket 3, and a swing arm 402 is provided at the output end of the forward and reverse motor 401. The swing arm 402 can swing from one side of the screening device 200 to the side of the core conveying device 2.

[0021] The mold core to be inserted is placed on the mold core loading conveyor 400, and the loading robot 500 transfers the mold core from the mold core loading conveyor 400 to the mold core conveying device 2, and the mold core conveying device 2 transports the mold core to the corresponding pin insertion station.

[0022] The pins are placed in the pin tray 100 and the screening device 200 aligns the pins so that the clamping arms 8 can clamp them accurately.

[0023] Adjusting the lateral displacement: Based on the lateral displacement requirements of the pin installation position for different mold core sizes, rotate the first adjustment screw 111. The first adjustment screw 111 engages with the first adjustment screw hole in the movable block 505, causing the movable block 505 to move within the lateral guide groove 504. This in turn drives the reverse L-shaped slider 502 and reverse L-shaped movable guide groove 503 to move, changing the width of the adjustable U-shaped guide groove 5 and, in turn, adjusting the lateral displacement of the clamping arm 8.

[0024] Adjusting the Descending Amount: Rotate the second adjusting screw 103 based on the required height of the pin installation position for different mold core sizes. The second adjusting screw 103 engages with the screw holes 101 at the bottom of the reverse L-shaped fixed guide groove 501 and the reverse L-shaped movable guide groove 503, allowing the height-limiting slider 102 to move up and down within the reverse L-shaped fixed guide groove 501 and the reverse L-shaped movable guide groove 503, limiting the downward movement distance of the movable shaft 6 and thereby adjusting the descending amount of the clamping arm 8.

[0025] The forward and reverse motors 401 are activated, driving the swinging rod 402 to swing. The swinging rod 402 swings from the side of the screening device 200 to the side of the core conveying device 2. During the swinging process, the linkage structure 7, i.e., the straight notch 300 on the swinging rod 402 cooperates with the movable shaft 6, causing the movable shaft 6 to move along the path of the adjustable U-shaped guide groove 5.

[0026] The movable shaft 6 drives the clamping arm 8 to move. The clamping arm 8 first picks up the pins aligned by the screening device 200 from the needle plate 100 and then, driven by the swinging rod 402, moves to the pin insertion position on the mold core. During this movement, the balancing guide mechanism 9 ensures the balance of the clamping arm 8. The fixed horizontal slide rail 901 and movable horizontal slide block 902 provide lateral sliding guidance, while the vertical guide hole 903 and vertical guide rod 904 provide vertical sliding guidance.

[0027] When the clamping arm 8 moves to the pin position of the mold core, due to the action of the height adjustment component 10, the clamping arm 8 drops to a suitable height and inserts the pin into the corresponding position of the mold core.

[0028] After the pin insertion is completed, the forward and reverse motor 401 drives the swing rod 402 to swing in the reverse direction, and the clamping arm 8 returns to the initial position to prepare for the next pin insertion operation.

[0029] The linkage structure 7 of the present invention includes a straight slot 300 provided on the swing rod 402 . The straight slot 300 is provided along the direction of the swing rod 402 , and the movable shaft 6 is movably inserted into the straight slot 300 .

[0031] The balancing guide mechanism 9 of the present invention includes a fixed horizontal slide rail 901 arranged on the pin bracket 3, a movable horizontal slider 902 is movably arranged in the fixed horizontal slide rail 901, a vertical guide hole 903 is provided on the movable horizontal slider 902, a vertical guide rod 904 is movably arranged in the vertical guide hole 903, and the clamping arm 8 is arranged on the vertical guide rod 904.

[0032] The width adjustment assembly 11 of the present invention includes a first adjustment screw 111 rotatably arranged in the transverse guide groove 504, and a first adjustment screw hole is provided in the movable block 505. The first adjustment screw 111 is movably inserted into the first adjustment screw hole and is threadedly connected to the first adjustment screw hole.

[0033] The height adjustment assembly 10 of the present invention includes a vertical adjustment limiting structure 1000 disposed in the reverse L-shaped fixed guide groove 501 and the reverse L-shaped movable guide groove 503 .

[0034] The vertical adjustment limit structure 1000 can adjust the height direction, thereby limiting the downward movement distance of the movable shaft 6 and ensuring that the clamping arm 8 can descend to reach the corresponding work station.

[0035] The vertical adjustment limit structure 1000 described in the present invention includes a screw hole 101 arranged at the bottom of the reverse L-shaped fixed guide groove 501 and the reverse L-shaped movable guide groove 503, and a height limiting slider 102 is arranged to move up and down in the reverse L-shaped fixed guide groove 501 and the reverse L-shaped movable guide groove 503. A second adjustment screw 103 is rotatably installed at the bottom of the height limiting slider 102, and the second adjustment screw 103 moves through the screw hole 101 and is threadedly connected to the screw hole 101.
