Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a structure of automotive sealing injection molded parts. Background Technology

[0002] Seals are crucial in automobiles. They prevent fluid and gas leaks, ensuring the proper functioning of fuel, cooling, braking systems, engine intake and exhaust systems, and air conditioning systems. They also prevent dust and moisture from entering, protecting the interior for cleanliness and comfort, as well as critical components and extending the lifespan of parts. They contribute to improving vehicle performance and reliability, such as enhancing power, ensuring smooth transmission operation, and improving handling and comfort. Furthermore, they meet environmental requirements by reducing emissions and preventing the leakage of harmful substances that pollute the environment.

[0003] Patent publication number "CN217784481U" discloses "A High-Temperature Resistant Automotive Seal," comprising a main pressure ring. First fixing blocks are fixedly connected to both sides of the outer surface of the main pressure ring. Positioning plates are fixedly connected to the bottom of each of the two first fixing blocks. A snap-fit ​​assembly is installed on the outer end face of each of the two positioning plates. An auxiliary assembly is installed on the top of each of the two first fixing blocks. A secondary pressure ring is provided at the bottom of the main pressure ring. Second fixing blocks are fixedly connected to both sides of the outer surface of the secondary pressure ring, and the second fixing blocks match the first fixing blocks. Positioning holes are provided on the top of each of the two second fixing blocks. By using positioning plates, positioning holes, snap-fit ​​assemblies, and auxiliary assemblies, the original bolt structure is replaced, avoiding loosening problems after prolonged use. Simultaneously, the main and secondary pressure rings can be pressed tightly against the pipeline without the aid of external tools, ensuring a tight fit between the high-temperature resistant sealing assembly and the pipeline.

[0004] The device in the aforementioned patent pushes an auxiliary frame upwards, which in turn moves a pull frame, causing the second fixing block to move closer to the first fixing block for engagement. However, if the auxiliary frame lacks limit control, it may shake and loosen when there is external shaking or excessive movement of the pipeline. This loosened auxiliary frame is very likely to cause the pull frame to detach from the second fixing block, resulting in problems such as device separation. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a structure for automotive sealing injection molded parts.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a structure for an automotive sealing injection molded part, including an upper annular frame and a lower annular frame, wherein the lower annular frame is disposed below the upper annular frame, and an upper connecting plate and a lower connecting plate are respectively fixedly installed on the two side surfaces of the upper annular frame and the lower annular frame, and an insertion mechanism and a control mechanism are respectively provided inside the upper connecting plate and the lower connecting plate.

[0009] The control mechanism includes a connecting block and a control frame. The bottom ends of the control frame are respectively hinged to the two end surfaces of the connecting block. The upper connecting plate has a limiting groove that runs through it. A second spring is fixedly installed on the bottom wall of the limiting groove, and a limiting block is fixedly installed on the top of the second spring.

[0010] By adopting the above technical solution, pulling the control frame can effectively cause the lower connecting plate and the upper connecting plate to cooperate and press together.

This solves the problem that if the auxiliary frame lacks limit control, it may shake and loosen when there is external shaking or excessive movement of the pipeline. Such a loose auxiliary frame may cause the pull frame to detach from the second fixing block, resulting in the separation of the device.

A first spring is fixedly installed on the inner wall of one side of the working groove, and a locking block is fixedly installed on one end of each of the first springs.

[0016] By adopting the above technical solution, the upper and lower annular frames can be limited by the insertion blocks that penetrate the top and bottom surfaces of the slot respectively. At the same time, the locking block ejected by the first spring can effectively exert the control function and prevent the insertion block from falling out of the slot.

[0017] In a preferred embodiment of the automotive sealing injection molding structure of this utility model, the slots of the insertion mechanism are respectively opened on the top surface of the lower connecting plate and penetrate through the bottom surface, the top ends of the insertion blocks are respectively fixedly installed on the bottom surface of the upper connecting plate, the outer sides of the card blocks are respectively slidably connected between the inner walls of the working groove, and the top surfaces of the card blocks are respectively attached to the bottom surface of the lower connecting plate.

[0018] By adopting the above technical solution, the upper connecting plate can effectively provide a stable working position for the insertion blocks installed on the bottom surface.

[0019] As a preferred embodiment of the automotive sealing injection molding structure of this utility model, sealing rings are respectively placed inside the upper annular frame and the lower annular frame, and reinforcing ribs are respectively fixedly installed on the outer surfaces of the upper annular frame and the lower annular frame. The bottom and top surfaces of the reinforcing ribs are respectively fixedly installed on the bottom surface of the lower connecting plate and the top surface of the upper connecting plate.

[0020] By adopting the above technical solution, reinforcing ribs are installed on the outer surfaces of the upper and lower annular frames respectively, with the bottom and top surfaces of the reinforcing ribs installed on the bottom surface of the lower connecting plate and the top surface of the upper connecting plate respectively. In this way, the added reinforcing ribs can improve the strength of the lower and upper connecting plates and prevent the lower and upper connecting plates from breaking due to excessive force.
