This requires a lot of time to disassemble and reinstall the fixture or mold, which greatly increases the production downtime. At the same time, defects such as missing material, flash, and bubbles in the product caused by mold positional deviation or component deformation reduce the product yield. Therefore, it is necessary to design a fixture structure for IMD molds that is easy to automatically correct. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 The present invention provides a technical solution as follows:

[0022] Example 1:

[0023] A fixture structure for IMD molds includes a fixture base 1, a connecting frame 2 mounted on the top of the fixture base 1, a guide rail 3 mounted on the top of the connecting frame 2, a movable seat 4 slidably mounted on the top of the guide rail 3, a straightening component 5 mounted on the top of the movable seat 4, a pad block 6 fixedly connected to the top of the fixture base 1, a drive cylinder 7 mounted on the top of the connecting frame 2, and a drive component 8 mounted on the top of the connecting frame 2.

[0024] The above structure, through the correction component 5, allows the jig to adjust the position of the four corners after clamping the IMD mold. Using the correction angle 504, the mold position is corrected under the drive of the electric telescopic rod 503. During the mold debugging stage, the jig structure that is easy to correct enables technicians to adjust the mold to the optimal state more quickly.

[0025] Furthermore, the internal components of the correction assembly 5 include a support rod 501, a connecting shaft 502, an electric telescopic rod 503, a correction angle 504, and a tension spring 505. The support rod 501 is fixedly connected to the top of the pad 6. The connecting shaft 502 is fixedly installed at one end of the support rod 501. The electric telescopic rod 503 is installed on the support rod 501 through the connecting shaft 502. The correction angle 504 is fixedly connected to the output end of the electric telescopic rod 503. The tension spring 505 is fixedly connected to the outer wall of the correction angle 504. There are four sets of correction angles 504, and the correction angles 504 are located at the four corners of the movable seat 4. The correction angle 504 is connected to another correction angle 504 through the tension spring 505. A sliding groove is provided above the movable seat 4, and the correction angle 504 slides along the sliding groove.

[0026] The above structure can achieve precise positioning of the mold and correct installation of parts through simple correction operations, reducing the number of repeated adjustments and time, and speeding up the trial molding and mass production of new products. At the same time, the correction angle 504 is made of silicone, and the fixture structure can ensure the correct fit and uniform force between the mold and the equipment.

[0027] Furthermore, the drive assembly 8 includes a central shaft 801, a balance plate 802, a mounting shaft 803, and a connecting rod 804. The central shaft 801 is mounted on the top of the connecting frame 2, and the balance plate 802 is connected to the top of the connecting frame 2 through the central shaft 801. The mounting shaft 803 is mounted on the outer wall of the balance plate 802, and the connecting rod 804 is connected to the balance plate 802 through the mounting shaft 803. A set of mounting shafts 803 is provided at each end of the balance plate 802, and the connecting rod 804 is diagonally mounted at both ends of the balance plate 802.

[0028] The above structure utilizes the drive component 8 to drive the movable seats 4 on both sides for clamping operations. The four-corner clamping structure makes the mold installation more stable. At the same time, there is no obstruction structure above the clamping, which reduces the impact of the clamping on the pressing and molding process.

[0029] Furthermore, the guide rails 3 are installed in parallel, and the movable seat 4 is slidably installed along the guide rails 3.

[0030] The above structure restricts the range of motion on both sides through guide rail 3.

[0031] Working principle: In use, firstly, the IMD mold is made by placing a pre-printed film sheet into the mold. Through processes such as injection molding, the plastic and the film sheet are tightly bonded together, forming a mold with decorative patterns or functional structures on the surface of the plastic product. The mold is fixed by the clamping fixture. The drive cylinder 7 is started to drive the mounting shaft 803 to move, thereby driving the balance plate 802 to rotate along the central axis 801, so that the connecting rod 804 pulls the movable seat 4, thereby fixing the mold in the middle position.

[0032] Secondly, through the correction component 5, the jig can automatically adjust the position of the four corners after clamping the IMD mold. Using the correction angle 504, the mold position is corrected under the drive of the electric telescopic rod 503. During the mold debugging stage, the easy-to-correct jig structure enables technicians to adjust the mold to the optimal state more quickly. The precise positioning of the mold and the correct installation of parts can be achieved through simple correction operations, reducing the number of repeated debugging times and time, and speeding up the trial molding and mass production progress of new products.

[0033] Finally, the correction angle 504 is made of silicone. The fixture structure ensures proper fit and uniform force between the mold and the equipment, avoiding excessive local stress on the equipment due to mold position deviation or unreasonable fixture, thereby reducing the operating burden of the equipment, lowering the failure rate, and extending the service life of the equipment. The fixture is equipped with a tension spring 505, which uses elastic elements. Elastic pads are used at the contact points between the fixture and the mold. When the mold position is slightly deviated, the rubber pads can adapt to the shape and position of the mold through their own elastic deformation, playing a role in buffering and correction.
