[0002] HDPE double-wall corrugated pipe, referred to as PE corrugated pipe, is a new type of lightweight pipe made of high-density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long life. Its excellent pipe wall structure design greatly reduces the cost compared with pipes with other structures. It is widely used at home and abroad due to its convenient and reliable connection, replacing concrete pipes and cast iron pipes in large quantities.

The gas delivery disk 602 can evenly guide the cooling gas to the inner mold 5, and the air pipe 601 and the gas delivery disk 602 are connected. The gas delivery disk 602 is evenly provided with nozzles 603 on the side facing the inner wall of the inner mold 5. The cooling gas in the gas delivery disk 602 is sprayed into the inner mold 5 through the nozzles 603.

[0024] like Figure 1-Figure 3 As shown, the driving assembly 3 includes a sliding seat 301 symmetrically mounted on the bottom of the first outer mold 1 and the second outer mold 2, and the sliding seat 301 is slidably connected to the support frame 4, so that the first outer mold 1 and the second outer mold 2 can be opened and closed along the support frame 4 through the sliding seat 301.

[0025] like Figure 1-Figure 2 As shown, a bidirectional lead screw 302 is threadedly connected inside the sliding seat 301, and a motor 9 is installed at one end of the bidirectional lead screw 302, and the motor 9 is fixed on the support frame 4, so that the motor 9 can drive the bidirectional lead screw 302 to rotate, thereby opening and closing the first outer mold 1 and the second outer mold 2.

[0026] like Figure 1-Figure 2 As shown, spiral grooves are provided on the opposite side walls of the first outer mold 1 and the second outer mold 2 to facilitate the molding of materials entering between the first outer mold 1, the second outer mold 2 and the inner mold 5.

[0027] like Figure 1-Figure 3 As shown, a cooling assembly 7 is provided on both the first outer mold 1 and the second outer mold 2. The cooling assembly 7 includes a cooling cavity 701, a water inlet rack 702 and a water outlet rack 703.

The inner wall of the sealing gasket 8 abuts against the outside of the inner mold 5, so that the sealing gasket 8 can seal both ends of the first outer mold 1 and the second outer mold 2 when the mold is closed.

[0030] like Figure 1 As shown, a feed pipe 10 is installed on one side of the first outer mold 1 and the second outer mold 2 to facilitate the material to enter between the first outer mold 1 and the second outer mold 2 and the inner mold 5 through the feed pipe 10 .

During the production process, cooling water enters the cooling cavity 701 through the water inlet rack 702, and then cools the first outer mold 1 and the second outer mold 2, so that the material is quickly cooled, and the used water is discharged through the drainage rack 703 At the same time, the cooling gas enters the inner mold 5 through the air pipe 601 in the cooling component 6, and then the cooling gas is diverted to the air delivery plate 602 through the air pipe 601. The diverted cooling gas is evenly blown onto the outer wall of the inner mold 5 through the nozzle, thereby cooling the inner mold 5 during the processing, which is convenient for pipeline cooling. By cooperating with the cooling component 7 of the outer mold, internal and external cooling is achieved, which facilitates the demoulding of the pipe and improves practicality. After the material is cooled and formed, the motor 9 drives the bidirectional screw 302 in the driving component 3 to rotate. During the rotation of the bidirectional screw 302, the first outer mold 1 and the second outer mold 2 are driven to separate from each other through the sliding block, and then demoulding can be performed.
