A first slot 502 is provided on one side of the first connecting block 501. Several first spring grooves 503 are formed on the inner wall of the first slot 502. A first through hole 504 passes through the inner wall of each first spring groove 503. A first spring 505 is fixedly connected to the inner wall of each first spring groove 503. A first snap-fit plate 506 is fixedly connected to the other end of each first spring 505. One side of the first snap-fit plate 506 is fixed... A first pull rod 507 is connected. Several first snap-fit grooves 508 are provided on one side of the outer surface of the stainless steel sleeve 2. One side of the stainless steel sleeve 2 is slidably installed inside the first slot 502. The first snap-fit grooves 508 are snap-fit connected to the first snap-fit plate 506. The first snap-fit grooves 508 are distributed equidistantly on one side of the outer surface of the stainless steel sleeve 2. The first pull rod 507 is slidably installed on the inner wall of the first through hole 504. A first sealing ring 509 is fixedly connected to one side of the outer surface of the stainless steel sleeve 2 and one side of the first connecting block 501.
[0021] More specifically, when installing protection between the Teflon wire 1 and the stainless steel sleeve 2, the first connecting block 501 is fixedly connected to one side of the Teflon wire 1, and one side of the stainless steel sleeve 2 is inserted into the first slot 502. The outer surface of the stainless steel sleeve 2 presses against the first snap-fit plate 506 and the first spring 505, pressing the first snap-fit plate 506 and the first spring 505 into the first spring groove 503. When one end of the stainless steel sleeve 2 contacts the inner wall of the first slot 502 and connects with one end of the Teflon wire 1, the first snap-fit plate 506 is snapped against the first snap-fit groove 508 under the elastic push of the first spring 505. The first sealing ring 509 is installed at the connection between the stainless steel sleeve 2 and the first connecting block 501 on one side for sealing.
[0022] A second connecting component 6 is provided on one side of the nickel rod 3; for example Figure 4 As shown, specifically, the second connecting component 6 includes a second connecting block 601 disposed on one side of the outer surface of the nickel rod 3. A second slot 602 is provided on one side of the second connecting block 601. Several second spring grooves 603 are provided on the inner wall of the second slot 602. A second through hole 604 is passed through the inner wall of the second spring groove 603. A second spring 605 is fixedly connected to the inner wall of the second spring groove 603. A second snap-fit plate 606 is fixedly connected to the other end of the second spring 605. A second pull rod 607 is fixedly connected to one side of the second snap-fit plate 606. Several second snap-fit grooves 608 are provided on the other side of the outer surface of the stainless steel sleeve 2. The second snap-fit grooves 608 are snap-fit connected to the second snap-fit plate 606. The other side of the stainless steel sleeve 2 is slidably installed on the inner wall of the second slot 602. A second sealing ring 609 is fixedly connected to one side of the outer surface of the stainless steel sleeve 2 and one side of the second connecting block 601.

When the stainless steel sleeve 2 moves on the inner wall of the second slot 602, the second snap-fit plate 606 and the second spring 605 are squeezed into the second spring groove 603. When one end of the stainless steel sleeve 2 moves to connect with one end of the nickel rod 3, the second snap-fit plate 606 is snapped into the second snap-fit groove 608 under the elastic push of the second spring 605. At this time, one end of the nickel rod 3 is connected to one end of the Teflon wire 1. The second sealing ring 609 is installed at the connection between the stainless steel sleeve 2 and one end of the second connecting block 601 for sealing.
[0024] In summary, this high-temperature resistant connection device for hot runners uses a stainless steel sleeve 2 fitted onto the connection between the Teflon wire 1 and the nickel rod 3. The temperature resistance range of the stainless steel sleeve 2 is between that of the Teflon wire 1 and the nickel rod 3, thus slowing down oxidation and protecting the connection between the Teflon wire 1 and the nickel rod 3. After connecting the Teflon wire 1 and the first connecting block 501, it is inserted into one side of the stainless steel sleeve 2 to achieve a snap-fit connection, thereby improving the tensile strength of the connection. After connecting the nickel rod 3 and the second connecting block 601, it is inserted into the other end of the stainless steel sleeve 2 to achieve a snap-fit connection. A first sealing ring 509 and a second sealing ring 609 are installed at the connection on both sides of the stainless steel sleeve 2 to achieve a seal and improve the protection effect.
