Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing equipment, in particular to a four-door, two-lid and multi-vehicle model mold switching system. Background Art

[0002] At present, the four-door and two-cover press lines in the automotive industry are usually used with a single-side "one-to-two" die-changing mechanism, which is relatively inflexible and can only be applied to two models. With the development of the automotive industry, die-changing mechanisms are increasingly inclined to multi-model, highly flexible design and layout. This change is conducive to reducing the direct costs incurred by the main engine factory when investing in new models, and improving the utilization rate of land resources by the main engine factory.

[0003] However, the existing highly flexible layout design usually expands the plane space on the ground, and the space requirements for the factory are still high. At the same time, the mold carrier in the mold changing mechanism cannot directly enter the press. When the press is working, the mold carrier still needs to occupy an additional storage space, resulting in the inability to release the storage space. It is difficult to use the working time of the press to adjust the position of the molds in the remaining storage spaces, and the use efficiency is low. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a four-door, two-lid and multi-vehicle mold switching system.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0029] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0030] like Figure 1 to Figure 3 As shown, this embodiment provides a four-door, two-lid, multi-vehicle mold switching system, including a main frame 1, a lifting frame 2, and a plurality of mold carriers 4, each of which is provided with a press mold 3. The main frame 1 includes a lifting area 16, a first storage position 11, a second storage position 12, a third storage position 13, a fourth storage position 14, and a carrier storage position 15. The lifting area 16 is located in the middle of the main frame 1, including a first layer and a second layer arranged in sequence from bottom to top, the first storage position 11 and the second storage position 12 are symmetrically arranged on both sides of the first layer of the lifting area 16, the third storage position 13 and the fourth storage position 14 are symmetrically arranged on both sides of the second layer of the lifting area 16, and the third storage position 13 and the fourth storage position 14 are respectively located above the first storage position 11 and the second storage position 12. The carrier storage position 15 is arranged between the fourth storage position 14 and the second storage position 12, and the top space of the carrier storage position 15 and the second storage position 12 overlaps, and the overlapping top space is the middle layer. The front end of one side of the lifting area 16 is connected to the press.

[0031] Lifting frame 2 Figure 4 As shown, it is arranged in the lifting area 16. The lifting frame 2 is connected to the hydraulic module, and moves up and down in the lifting area 16 under the drive of the hydraulic module. A locking mechanism 8 is provided at the top of the lifting area 16, which is used to limit the moving position of the lifting frame 2, so that the lifting frame 2 can stop and lock the position at the first floor, the second floor or the middle floor. A sensor is provided in the lifting area 16 to lock the lifting frame 2 when it moves to the corresponding position. When the lifting frame 2 stops at the first floor, the first storage position 11 and the second storage position 12 are connected on both sides, and the front end of the lifting frame 2 is connected to the press; when the lifting frame 2 stops at the second floor, the third storage position 13 and the fourth storage position 14 are connected on both sides; when the lifting frame 2 stops at the middle floor, one side is connected to the carrier storage position 15.

[0032] The first storage position 11, the second storage position 12, the third storage position 13, the fourth storage position 14 and the carrier storage position 15 are provided with a carrier driving mechanism 5 for moving the mold carrier 4, moving the mold carrier 4 from the storage position to the lifting frame 2, or moving the mold carrier 4 from the lifting frame 2 to the storage position. The lifting frame 2 is provided with a carrier fixing mechanism 7 and a mold driving mechanism 6, which cooperate to keep the mold carrier 4 in the lifting frame 2, move the press mold 3 from the lifting frame 2 to the press, or move the press mold 3 from the press to the mold carrier 4 in the lifting frame 2. The carrier fixing mechanism 7 is as shown in FIG. Figure 5 As shown, the fixtures for connecting the micro motors are distributed at the four corners of the bottom of the lifting frame 2. Position sensors are provided inside the first storage position 11, the second storage position 12, the third storage position 13, the fourth storage position 14 and the carrier storage position 15 to ensure that the mold carrier 4 moves into place. Roller guides are also provided inside the first storage position 11, the second storage position 12, the third storage position 13, the fourth storage position 14 and the carrier storage position 15, and one end of the roller guide faces the lifting area 16, so that the movement of the mold carrier 4 is more stable and smooth.

[0033] like Figure 6 As shown, the locking mechanism 8 includes a cylinder 81, a fixing portion 82 and a clamping portion 83. The clamping portion 83 is provided with a plurality of protrusions 84, and the clamping portion 83 is rotatably connected to the fixing portion 82 and the cylinder 81. When the cylinder 81 is extended and retracted, the clamping portion 83 is driven to rotate around the fixing portion 82, so that the protrusions 84 are pressed against the bottom of the lifting frame 2 to form a lock. There are two protrusions 84, which are used to lock the second layer and the middle layer respectively. There are at least four locking mechanisms 8. In this embodiment, four locking mechanisms 8 are used and distributed at the four corners of the top of the lifting frame 2.

The front end of the carrier driving guide rail 52 faces the lifting area 16, and the carrier driving motor 51 is fixed to the rear end of the carrier driving guide rail 52. The chain is arranged in the carrier driving guide rail 52, one end of which is connected to the carrier driving claw 53, and the other end is connected to a sprocket, and the sprocket is connected to the carrier driving motor 51. Therefore, the rotation of the carrier driving motor 51 can drive the sprocket to rotate, so that the chain moves in the carrier driving guide rail 52, thereby moving the carrier driving claw 53. Figure 8 As shown, at both ends of the mold carrier plate 4, there are clamping blocks 41 for connecting the carrier plate driving claws 53. The carrier plate driving claws 53 have an automatic opening and tightening structure, which is an existing mature technology and is not expanded.

[0035] The mold driving mechanism 6 includes a mold driving motor 61 and a structure that is basically the same as that of the carrier driving mechanism 5, including a mold driving motor 61, a mold driving guide rail 62, a mold driving claw 63 and a chain. The front of the mold driving guide rail 62 faces the press, and the mold driving motor 61 is fixed to the rear end of the mold driving guide rail 62. The chain is arranged in the mold driving guide rail 62, one end of which is connected to the mold driving claw 63, and the other end is connected to a sprocket, which is connected to the mold driving motor 61. The difference between the mold driving motor 61 and the carrier driving mechanism 5 is that the mold driving claw 63 and the carrier driving claw 53 are different in shape and height, and the mold driving claw 63 is tightly used to move the press mold 3, and one end of the press mold 3 is provided with a clamping groove for connecting the mold driving claw 63.
