[0002] The "seatbelt rack" is a key mechanical structure in automotive seatbelt pretensioners, and one of the core actuators of pyrotechnic pretensioning devices. Its function is to quickly tighten the seatbelt when a vehicle collision occurs, reducing injuries to occupants caused by forward inertia. During the production and processing of seatbelt racks, they are usually stamped using a flashless stamping die. A flashless stamping die is a special type of stamping die whose main feature is that it can avoid generating flash during the stamping process, thereby improving material utilization, reducing subsequent processing steps, and lowering production costs.
[0003] Existing flashless stamping dies typically use guide posts to guide and restrict the upper and lower dies during use. However, these guide posts are usually installed inside the die and run through the die, making them inconvenient to disassemble and replace when wear or other malfunctions occur. Therefore, we propose a safety belt rack flashless stamping die. Utility Model Content

[0043] The connecting positioning mechanism 7 is fixedly installed inside the connecting shielding and protective mechanism 6, and its end is connected and fixed to the threaded hole 3 by bolts.
[0044] The working principle of the above technical solution is as follows:
[0045] During use, the connecting guide mechanism 4 provides stable guidance between the first mold 1 and the second mold 2. Furthermore, if wear occurs on the surface of the connecting guide mechanism 4 during subsequent use, it can be quickly disassembled and replaced. When the first mold 1 and the second mold 2 are no longer in use, the connecting shielding and protective mechanism 6 and the connecting positioning mechanism 7 are installed, ensuring a stable connection and stable storage. The overall structure is simple and the operation is convenient and quick.
[0046] In another embodiment, such as Figure 4As shown, the connecting guide mechanism 4 includes a first connecting block 41, a first connecting leg 42, a second connecting block 44, and a second connecting leg 45, respectively located inside the mounting grooves on the sides of the first mold 1 and the second mold 2. The end of the first connecting leg 42 is fixedly connected to the end edge of the first connecting block 41, and the end of the second connecting leg 45 is fixedly connected to the end edge of the second connecting block 44. A fixed guide post 43 is fixedly connected to the top of the first connecting block 41, and the interior of the second connecting block 44 has a section corresponding to the fixed guide post 43. The outer side of the top surface of the fixed guide post 43 slides and fits against the inner side of the through hole at the top of the second mold 2. The top of the fixed guide post 43 is fixedly connected to a connecting top block 46. The top of the connecting top block 46 is fixedly connected to a fixed threaded rod 47. A connecting limiting plate 48 is movably sleeved on the outer side of the surface of the connecting top block 46. A fixed through groove 49 is opened inside the connecting limiting plate 48. A movable limiting plate 410 is movably sleeved on the outer side of the surface of the fixed threaded rod 47. A fastening nut 411 is threadedly connected to the outer side of the surface of the fixed threaded rod 47.
[0047] To facilitate the installation of the second connecting block 44 and the second connecting leg 45 on the inner side of the mounting groove on the side of the second mold 2, the first connecting leg 42 and the first connecting block 41 are installed on the inner side of the mounting groove on the side of the first mold 1. Then, the second mold 2 moves the second connecting block 44 and the second connecting leg 45 to fit onto the outer surface of the fixed guide post 43. Finally, the connecting limiting plate 48 is fitted onto the outer surface of the connecting top block 46 under the action of the fixed through groove 49.

A connecting protective plate 62 is fixedly connected to one side of the connecting plug 61. A connecting auxiliary limiting block 63 is fixedly connected to the inner side of the connecting protective plate 62. A fixing groove 64 is provided on one side of the connecting auxiliary limiting block 63.
[0051] This allows the connecting plug 61 to be inserted into the inner side of the fixed mounting frame 5, and the connecting auxiliary limiting block 63 to be positioned outside the fixed guide post 43 under the action of the fixed groove 64, thereby enabling connection.
[0052] In another embodiment, such as Figure 5 As shown, the bottom of the connecting auxiliary limiting block 63 is in contact with the top of the second mold 2, and the inner surface of the fixing groove 64 is in contact with the outer surface of the fixing guide post 43.
[0053] The auxiliary limiting block 63 is easily connected and can be stably positioned outside the fixed guide post 43 under the action of the fixed groove 64, thus providing stable protection for the fixed guide post 43.
[0054] In another embodiment, such as Figure 5 As shown, the connection positioning mechanism 7 includes a fixed connecting block 71 located on one side of the connection protective plate 62.

Simultaneously, the first connecting leg 42 and the first connecting block 41 are installed inside the side mounting groove of the first mold 1. Then, the second mold 2 moves the second connecting block 44 and the second connecting leg 45, fitting them onto the outer surface of the fixed guide post 43. Finally, the connecting limiting plate 48, under the action of the fixed through groove 49, is fitted onto the outer surface of the connecting top block 46. Next, the movable limiting plate 410 is fitted onto the outer surface of the fixed threaded rod 47, and the fastening nut 411 is connected and installed with the fixed threaded rod 47. The entire assembly is then connected and assembled, guiding the first mold 1 and the second mold 2. In subsequent use, if the fixed guide post 43 wears down, it can... The connecting guide mechanism 4 can be quickly disassembled and replaced. When the whole is no longer in use, first insert the connecting plug 61 into the inside of the fixed mounting frame 5, so that the connecting auxiliary limiting block 63 is on the outside of the surface of the fixed guide post 43 under the action of the fixed groove 64. Then, insert the movable mounting clip 73 into the inside of the movable mounting clip 73, and connect and fix the connecting sealing block 76 and the fixed connecting block 71 with bolts. Then, move the movable mounting clip 73 downward, driving the fixed connecting arm 74 and the movable mounting clip 73 downward, so that the fixed connecting arm 74 can be at the top of the second mold 2, so that the fixed connecting arm 74 and the second mold 2 are connected and fixed with bolts, so that the whole is in a stable connection state, and the whole can be stored stably. The overall structure is simple and the operation is convenient and quick.
