[0028] The replacement part 1 4 includes: a trapezoidal clamping plate 413, which is slidably connected to the inside of the sliding groove 1; and a rotating rod 414, which is rotatably connected to the inside of the adapter port 1.

Conversely, the card rod 418 is pulled so that the card rod 418 is no longer engaged with the card groove, so as to achieve the effect of quickly disassembling and replacing the outer mold 412. Example

[0032] On the basis of Example 1, the preferred embodiment of the extrusion die for producing PE pipes with various pore sizes provided by the present invention is as follows: Figure 1-6 As shown: the replacement part 5 includes: an inner mold 511, which is slidably connected to one side of the mold mounting cylinder 3; a blocking block 513, which is fixedly connected to the bottom of the inner wall of the adapter port 2, and the blocking blocks 513 are equidistantly arranged around the circumference; a fixing frame 514, which is fixedly connected to the inner wall of the adapter port 2, and the fixing frame 514 is equidistantly arranged around the circumference; and a cross brake plate 518, which is slidably connected to the inner wall of the adapter port 2.

[0033] The top of the inner mold 511 is fixedly connected with a cross clamping plate 512, which is adapted to the connecting groove. A slide three is opened on one side of the fixed frame 514. The interior of the fixed frame 514 is slidably connected with a trapezoidal clamping block 515, which is engaged and connected with the cross clamping plate 512. One end of the trapezoidal clamping block 515 is fixedly connected with a connecting plate 516, which is slidably connected to the inside of the slide three, and the connecting plate 516 is adapted to the cross brake plate 518.

[0034] A spring three 517 is provided between the trapezoidal block 515 and the second adapter port. One end of the spring three 517 is fixedly connected to the top of the trapezoidal block 515 , and the other end of the spring three 517 is fixedly connected to the inner wall of the second adapter port.

[0035] One end of the cross brake plate 518 is slidably connected to the inside of the slide 2, and a spring four 519 is arranged between the cross brake plate 518 and the slide 2. One end of the spring four 519 is fixedly connected to the top of the cross brake plate 518, and the other end of the spring four 519 is fixedly connected to the top of the inner wall of the slide 2. The outer wall of the cross brake plate 518 is fixedly connected to the brake ring 520, and the brake ring 520 is slidably connected to the outer wall of the mold mounting cylinder 2 3.

[0036] Furthermore, this embodiment lifts the inner mold 511 so that the inner mold 511 controls the cross clamping plate 512 to be inserted into the connecting groove, thereby rotating the inner mold 511, so that one side of the cross clamping plate 512 squeezes the trapezoidal clamping block 515, thereby lifting the trapezoidal clamping block 515. When one side of the cross clamping plate 512 abuts against one side of the blocking block 513, the trapezoidal clamping block 515 slides down under the action of spring three 517, thereby achieving the effect of clamping and fixing the cross clamping plate 512. Conversely, the brake ring 520 is lifted so that the brake ring 520 drives the cross brake plate 518 to slide up, thereby causing the cross brake plate 518 to drive the connecting plate 516 to slide up, thereby causing the trapezoidal clamping block 515 to no longer be clamped and connected to the cross clamping plate 512, and the inner mold 511 is rotated in the opposite direction so that the other side of the cross clamping plate 512 abuts against the blocking block 513, thereby achieving the purpose of quickly disassembling and replacing the inner mold 511.

[0037] When in use, first, the trapezoidal card plate 413 is inserted into the interior of the slide groove 1, and then the trapezoidal card plate 413 is pressed against the brake rod 415, so that the brake rod 415 drives the rotating rod 414 to rotate around the axis, so that the rotating rod 414 drives the transmission rod 416 to slide, so that the transmission rod 416 drives the card rod 418 to slide along the track of the slide groove 1. When the trapezoidal card plate 413 is fully inserted, under the action of the card rod 418's own gravity and the action of the spring 2 419, the card rod 418 is engaged with the card groove to achieve the effect of fixing the outer mold 412. On the contrary, the card rod 418 is pulled so that the card rod 418 is no longer engaged with the card groove, thereby achieving the purpose of quickly disassembling and replacing the outer mold 412; secondly, the inner mold 511 is lifted up so that the inner mold 511 controls the cross card plate 5 12 is inserted into the connecting groove, thereby rotating the inner mold 511, so that one side of the cross clamping plate 512 squeezes the trapezoidal clamping block 515, thereby lifting the trapezoidal clamping block 515. When one side of the cross clamping plate 512 abuts against one side of the blocking block 513, the trapezoidal clamping block 515 slides down under the action of spring three 517, thereby achieving the effect of clamping and fixing the cross clamping plate 512. Conversely, the brake ring 520 is lifted up, so that the brake ring 520 drives the cross brake plate 518 to slide up, so that the cross brake plate 518 drives the connecting plate 516 to slide up, so that the trapezoidal clamping block 515 no longer clamps and connects to the cross clamping plate 512, and the inner mold 511 is rotated in the opposite direction so that the other side of the cross clamping plate 512 abuts against the blocking block 513, thereby achieving the purpose of quickly disassembling and replacing the inner mold 511.
