[0002] IMG negative mold adsorption technology is currently widely used in automotive interiors. The parts production process of the IMG process is: 1. First place the plastic skeleton in the lower mold and fix it in position; 2. Transfer the heated leather material to the top of the lower mold; 3. The upper and lower molds are clamped together and vacuumed to adsorb the required leather texture, and at the same time, the skin is bonded to the plastic skeleton; 4. The mold is opened, the lower mold ejects the plastic skeleton, and the product is taken out, completing the production process of the IMG process.
[0003] Generally, plastic parts are positioned and fixed in IMG by vacuum suction cups. However, due to the size and vacuum force of the vacuum suction cups, if the skeleton is greatly deformed, it is difficult to fix the plastic skeleton in the IMG mold, and warping is likely to occur. This will have a great impact on the IMG molding process. Therefore, a better fixing method is needed to solve the problem of unstable positioning caused by skeleton deformation.

[0020] See also Figures 1-4 The utility model provides a technical solution: a clamping claw tooling for fixing parts in an IMG mold, comprising a cylinder 2 and a fixing sleeve 3, wherein the lifting end of the cylinder 2 is fixedly connected to the fixing sleeve 3 by bolts, a movable groove 4 is penetrated through the fixing sleeve 3, a fixing clamp 5 is movably arranged in the movable groove 4, a clamping point 13 for clamping a plastic frame 1 is fixedly arranged on the top side wall of the fixing frame 5, a through hole 7 is arranged on one side of the bottom of the fixing sleeve 3, and a rotating pin 6 fixed in the mold is rotatably connected to the through hole 7, A threaded hole 9 is penetrated through the side of the movable groove 4 away from the cylinder 2, and a stud 10 is threadedly connected to the threaded hole 9. A limit block 12 for abutting against the inner wall of the mold is provided on the side of the stud 10 away from the cylinder 2. An adjustment seat 14 is fixedly provided on the side of the fixing clamp 5 located above the fixing sleeve 3. An adjustable sliding rod 16 is provided in the adjusting seat 14. A connecting rod 17 is fixedly connected to the side of the sliding rod 16 away from the adjusting seat 14. A limit block B 18 abutting against the inner wall of the mold is provided on the side of the connecting rod 17 away from the adjusting seat 14.
[0021] Specifically, the width of the movable groove 4 is greater than the width of the fixing clip 5. A positioning ring 8 is fixed on the rotating pin 6 on both sides of the fixing clip 5. The positioning ring 8 fits with the side wall of the fixing clip 5. The fixing clip 5 can swing within a certain range in the movable groove 4 around the rotating pin 6. The movement of the fixing sleeve 3 is driven by the cylinder 2 to control the movement of the fixing clip 5, so that the fixing clip 5 has a certain inclination angle to match the clip strip on the plastic frame 1, so that the fixing clip 5 fits with the clip strip on the plastic frame 1, and the card point 13 is inserted into the through hole on the card strip.
[0022] Specifically, a pressing plate 11 that abuts against the side wall of the fixed sleeve 3 is fixedly provided on the stud 10, preventing the stud 10 from being screwed into the moving groove 4 too much and interfering with the movement of the fixed clamp 5. After the air cylinder 2 pushes out and the A limit block 12 touches one inner wall of the mold and stops, the fixed clamp 5 and the clamping point 13 are disengaged from the clamping strip of the plastic skeleton 1. The position of the A limit block can be adjusted by adjusting the position of the stud 10 in the threaded hole 9, thereby improving the adaptability.
[0023] Specifically, both the A limit block 12 and the B limit block 18 are rubber blocks, reducing the wear between the A limit block 12 and the B limit block 18 and the inner wall of the mold. The B limit block 18 is threadedly connected to the connecting rod 17, facilitating the replacement of the B limit block 18.
[0024] Specifically, a sliding groove 15 for the sliding rod 16 to slide is opened in the adjusting seat 14. An abutting column groove 19 is opened on the inner wall of the sliding groove 15. An abutting column 20 for abutting against the sliding rod 16 is slidably arranged in the abutting column groove 19. A threaded groove 21 is opened at one end of the abutting column 20 located in the abutting column groove 19. A screw rod 22 is threadedly connected in the threaded groove 21. A rotating groove 23 for the screw rod 22 to pass through and rotatably connected to the screw rod 22 is opened at the bottom of the abutting column groove 19. A knob 24 is fixedly connected to one end of the screw rod 22 located outside the rotating groove 23. After the air cylinder 2 contracts and the A limit block 12 abuts against the other inner wall of the mold and stops, at this time, the fixed clamp 5 is attached to the clamping strip of the plastic skeleton 1, and the clamping point 13 is inserted into the through hole of the clamping strip of the plastic skeleton 1. Adjusting the position of the A limit block 12 can make the fixed clamp 5 adapt to the fixation of different types of plastic skeletons 1. Rotating the knob 24 drives the screw rod 22 to rotate. Through the threaded connection between the screw rod 22 and the threaded groove 21, the abutting column 20 slides in the abutting column groove 19, thereby realizing the abutting and loosening of the abutting column 20 against the sliding rod 16, enabling the sliding rod 16 to slide and adjust its position and be positioned in the sliding groove 15, thereby adjusting the position of the B limit block 18.
[0025] Specifically, a limiting ring groove 25 is annularly opened on the inner wall of the rotating groove 23. A limiting ring 26 is rotatably arranged in the limiting ring groove 25. The limiting ring 26 is fixedly sleeved on the screw rod 22. Through the limitation of the limiting ring 26 and the limiting ring groove 25, the axial movement of the screw rod 22 is prevented.
[0026] A specific application example of this embodiment is:
[0027] When this device is in use, the plastic skeleton 1 is placed into the mold, and the vacuum suction cup positions the plastic skeleton 1 (this is the prior art of the comparative document). The air cylinder 2 contracts until the A limit block 12 abuts against the inner wall of one side of the mold and then stops. At this time, the fixed clamp 5 fits against the strip of the plastic skeleton 1, and the clamping point 13 is inserted into the through hole of the strip of the plastic skeleton 1, thereby further positioning the plastic skeleton 1. Multiple claw toolings fix multiple strips of the plastic skeleton 1, thus ensuring the stable positioning of the plastic skeleton 1. After processing is completed, the air cylinder 2 extends until the A limit block 12 touches the inner wall of one side of the mold and then stops, so that the fixed clamp 5 and the clamping point 13 are disengaged from the strip of the plastic skeleton 1 and lose the positioning of the plastic skeleton 1. The plastic skeleton is ejected by the lower mold to complete the part taking. The position of the A limit block can be adjusted by adjusting the position of the stud 10 in the threaded hole 9. Rotating the knob 24 drives the screw rod 22 to rotate. Due to the threaded connection between the screw rod 22 and the threaded groove 21, the pressing column 20 slides in the pressing column groove 19, thereby realizing the pressing and loosening of the pressing column 20 against the sliding rod 16, enabling the sliding rod 16 to slide and adjust its position and be positioned in the sliding groove 15, thereby adjusting the position of the B limit block 18, so that the fixed clamp 5 can be adapted to a variety of plastic skeletons, improving the practicality.
