Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 This utility model provides a technical solution: The door panel hot plate welding fixture disclosed in this utility model is mainly used in the field of ultra-thin hot plate welding, especially for the pressing and welding of automotive sun visors. It aims to solve the problems of cumbersome replacement of existing sun visor welding fixtures, inconvenient disassembly and assembly of modules, and poor integration. Its specific implementation structure is as follows.

[0020] This fixture uses a mold changing frame 1 as its core support plate and a hot plate 6 as its welding fixture. It integrates the core operating components required to complete the welding process, such as the upper hot mold 2, the lower hot mold (located on the lower side corresponding to the upper hot mold), the upper cold mold 4, and the lower cold mold 5. It is also equipped with a slide rail 16 to achieve overall movement and positioning. The upper hot mold 2 and the lower hot mold are fixedly connected by the hot plate 6 to form an integral structure. Both the upper hot mold 2 and the lower hot mold are provided with a core that mates with half of the sunshade. The upper cold mold and the lower cold mold 5 are provided with cavities for the half of the sunshade to be embedded on the side near the hot plate 6. The specific structure of the upper hot mold 2, the lower hot mold, the upper cold mold 4, and the lower cold mold 5 is existing technology and will not be described in detail.

[0021] A back plate 8 is fixedly provided at the end of the mold changing frame 1 away from the end baffle 18 of the slide rail 16. The output end of the back cylinder 7 installed on the back plate 8 is fixedly connected to the hot plate 6 to provide power for the back and forth movement of the hot mold. A fixing plate 9 is provided on the side of the mold changing frame 1 near the baffle 18. A guide rail rod 10 is mounted parallel between the fixing plate 9 and the back plate 8. Grooves 11 that are adapted to the guide rail rod 10 are opened on both sides of the hot plate 6. Through the sliding cooperation between the groove 11 and the guide rail rod 10, the upper hot mold 2 and the lower hot mold can slide stably back and forth along the mold changing frame 1 under the drive of the back cylinder 7. The upper cold mold 4 is positioned directly above the upper hot mold 2, and the lower cold mold 5 is positioned directly below the lower hot mold. Side extension plates 12 are symmetrically provided on both sides of the upper and lower cold molds. Guide rods 13 are fixed parallel to each other on both sides of the mold changing frame 1. The guide rods 13 pass vertically through the side extension plates 12 of the upper and lower cold molds. The side extension plates 12 can slide up and down along the guide rods 13 to realize the lifting and lowering adjustment of the cold molds. An upper cylinder 14 is installed at the bottom of the mold changing frame 1, and its bottom output end is fixedly connected to the top of the upper cold mold 4. A lower cylinder 15 is installed at the bottom of the mold changing frame 1, and its top output end is fixedly connected to the top of the lower cold mold 5. The upper cold mold 4 and the lower cold mold 5 are precisely lifted and lowered along the guide rods 13 by the extension and retraction of the upper and lower cylinders 15.

[0022] To enable rapid switching and positioning of the fixture, the bottom of the mold changing frame 1 is equipped with a moving wheel 17 that is compatible with the slide rail 16. The mold changing frame 1 can slide along the slide rail 16 as a whole to the welding station through the rolling cooperation between the moving wheel 17 and the slide rail 16. A baffle 18 is also fixed at the end of the slide rail 16 to limit the sliding endpoint of the mold changing frame 1. The slide rail 16 is provided with a limiting component for fixing the position of the mold changing frame 1. This component consists of a rack 19 and a gear 20. At the bottom of the end of the mold changing frame 1 that slides along the slide rail 16 toward the baffle 18, two sets of parallel side plates 21 are fixedly provided. The gear 20 is rotatably mounted between the two sets of side plates 21 through a one-way bearing 22 (a rotating rod is provided on both sides of the gear 20 along the axial direction, and the one-way bearing 22 is sleeved on the rotating rod. The inner side of the side plate 21 is provided with a circumferential groove for the one-way bearing 22 to be embedded). The slide rail 16 is provided with a rack groove 23 for the rack 19 to slide up and down at the position corresponding to the gear 20. An extension plate 24 extends integrally from one side of the rack 19. One end of the extension plate 24 extends out of the slide rail 16 and is connected to a pedal 25. The extension plate 24 can drive the rack 19 to slide up and down along the slide rail 16. A limiting plate 26 is fixedly provided at the bottom of the rack 19. A limiting side groove 27 is opened at the corresponding position on the inner wall of the rack groove 23 for the limiting plate 26 to be inserted and slide. A spring 28 is also installed at the bottom of the rack groove 23. The bottom end of the spring 28 is fixed to the bottom of the rack groove 23, and the top end is fixed to the bottom of the rack 19. In the natural state, the spring 28 pushes the rack 19 upward, so that the rack 19 and the gear 20 are kept in a meshing state. In addition, a bolt 29 is threadedly connected to the slide rail 16 at the rack 19. A locking hole 30 is opened on the rack 19 for one end of the bolt 29 to be inserted. When the rack 19 rises to the meshing position and the mold changing frame 1 contacts the baffle 18, the bolt 29 can be tightened to lock and fix the rack 19, further improving the limiting stability.

[0023] To prevent the mold changing frame 1 from rigidly impacting the baffle 18 when it slides to the work station, a buffer assembly is provided on the side of the mold changing frame 1 near the baffle 18. This assembly includes a buffer rod 31, a buffer spring 32, and inner and outer limit plates 33. A rod groove 35 is provided on the mold changing frame 1 at the position corresponding to the baffle 18. The buffer rod 31 slides through the rod groove 35. An outer limiting plate 33 is fixed at its outer end, and an inner limiting plate 34 is fixed at one end inside the mold changing frame 1. An inner limiting groove is provided at the inner end of the rod groove 35 to allow the inner limiting plate 34 to slide, which can prevent the buffer rod 31 from coming out of the rod groove 35. A buffer spring 32 is sleeved on the buffer rod 31. A hidden groove 36 is provided at the opening of the rod groove 35 to allow the outer limiting plate 33 to slide in. One end of the buffer spring 32 abuts against the outer limiting plate 33, and the other end is fixed to the inner end of the hidden groove 36. When the mold changing frame 1 approaches the baffle 18, the outer limiting plate 33 contacts the baffle 18 first, and the buffer rod 31 slides inward and compresses the buffer spring 32. The impact energy is absorbed by the deformation of the spring 28.

[0024] When the mold changing frame 1 is switched as a whole, the bolt 29 is rotated to disengage the bolt 29 from the rack 19. The pedal 25 is pressed down to drive the extension plate 24 and the rack 19 to slide downwards. The rack 19 compresses the spring 28 and disengages from the gear 20, losing its limit. At this time, the mold changing frame 1 can slide freely along the slide rail 16 via the moving wheel 17. Under the action of the buffer spring 32, the mold changing frame 1 will be pushed out of the slide rail 16. After the mold changing frame 1 is pushed out of the slide rail 16, the rack 19 is locked again by the bolt 29. When the mold changing frame 1 to be used is pushed to the welding station, the buffer component on the side of the mold changing frame 1 closest to the baffle 18 contacts the baffle 18 to achieve buffering. After the mold changing frame 1 moves to the welding station, the movement of the mold changing frame 1 will be restricted because the gear 20 and the rack 19 are in the meshing turntable and under the action of the one-way bearing 22. The mold changing frame 1 is locked in the welding station, completing the final positioning. During welding, the back cylinder 7 drives the hot mold to move to the welding position for heating. Then the hot mold retracts, the upper cylinder 14 drives the upper cooling mold to descend, and the lower cylinder 15 drives the lower cooling mold 5 to rise to press and cool the sunshade. The whole process does not require disassembling the module, achieving efficient operation and quick mold change (it should be noted that in order to facilitate the movement of the mold change frame into the slide rail, a platform 37 can be connected to the outer end of the slide rail. When the mold change frame needs to slide into the slide rail, it can be moved to the platform first).

[0025] In summary, this embodiment integrates each working module into the mold changing frame 1, and with the slide rail 16, limit components and buffer components, realizes the overall movement, automatic positioning and impact buffering of the fixture, effectively solves the problem of cumbersome replacement of traditional fixtures, and improves the continuity and convenience of welding operations.
