[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: an HDPE double-wall corrugated pipe extrusion molding equipment, including an extrusion molding component 1, an installation and removal component 2 on the extrusion molding component 1, and a cooling component 3 on the top of the extrusion molding component 1. The extrusion molding component 1 includes an extruder 101 and a conveyor belt 106. One end of the extruder 101 is connected to an extrusion port 105. Drive rollers 107 are symmetrically installed inside the conveyor belt 106, and multiple pipe wall forming molds 108 are distributed on the outer side of the conveyor belt 106, one of which... One end of the drive roller 107 is equipped with a motor 109. The cooling assembly 3 includes a support frame 301. A cooling pipe 302 is provided inside the support frame 301. One end of the cooling pipe 302 is provided with a coolant inlet 303. The other end of the coolant inlet 303 is provided with a coolant outlet 304. A heating pipe 104 is provided on the outside of the extruder 101. Heaters 103 are connected to both ends of the heating pipe 104. An insulation shell 110 is provided on the outside of the heating pipe 104. A feed inlet 102 is connected to the top of the extruder 101.

[0023] In this embodiment, HDPE granules are poured into the extruder 101 through the feed inlet 102. The screw conveyor 204 is driven by the motor 203 to rotate, and the heater 103 works in conjunction with the heating tube 104 to uniformly release heat, thereby heating the material inside the extruder 101. The material melts and is discharged through the extrusion port 105. The conveyor belt 106 is driven by the motor 109 to rotate, thereby driving the pipe wall forming die 108 to rotate to the extrusion port 105. The material enters the pipe wall forming die through the extrusion port 105. The interior of 108 facilitates the extrusion of double-walled corrugated pipes. By adding coolant into the interior of cooling pipe 302 through coolant inlet 303 and coolant outlet 304, the coolant is easily discharged, promoting the flow of coolant within cooling pipe 302. This facilitates cooling and reducing the temperature of the corrugated pipe, shortening the waiting time and improving production efficiency. Support bracket 301 supports the corrugated pipe and facilitates heat exchange during support, improving cooling efficiency and facilitating subsequent use. Electric push rod 305 allows for height adjustment of support bracket 301.

[0024] Example 2: As Figures 1-4 As shown, the assembly 2 includes a cover plate 202, a motor 203 mounted on one side of the cover plate 202, a screw conveyor 204 mounted on the other side of the cover plate 202, insert blocks 205 symmetrically mounted on the side of the cover plate 202, insert parts 206 symmetrically mounted on the outside of the extruder 101, insert blocks 205 penetrating the interior of insert parts 206, an electric push rod 305 mounted at the bottom of the support frame 301, a base plate 111 mounted at the bottom of the electric push rod 305, a limit bolt 207 penetrating the side of the insert part 206, the screw conveyor 204 being located inside the extruder 101, and a sealing ring 201 mounted at one end of the extruder 101.

[0025] In this embodiment, by placing the cover plate 202 at one end of the extruder 101, the sealing ring 201 facilitates the sealing effect, causing the insert block 205 to be inserted into the insert 206. Finally, the limiting bolt 207 is threaded through the insert 206, which facilitates the limiting and makes it easier to remove the screw conveyor 204 from the extruder 101. This facilitates the cleaning and maintenance of the screw conveyor 204, ensures the normal use of the screw conveyor 204, and improves work efficiency.

[0026] The working principle of this embodiment is as follows: In use, HDPE granules are first poured into the extruder 101 through the feed inlet 102. The screw conveyor 204 is driven by the motor 203 to rotate, simultaneously working with the heater 103 to ensure the heating tube 104 releases heat evenly, thus heating the material inside the extruder 101. The material melts and is discharged through the extrusion port 105. The conveyor belt 106 is driven by the motor 109 to rotate, thereby rotating the pipe wall forming die 108 to the extrusion port 105. The material enters the pipe wall forming die 108 through the extrusion port 105, facilitating the extrusion of double-wall corrugated pipes. Coolant is added to the cooling pipe 3 through the coolant inlet 303. Inside the 02, the coolant outlet 304 facilitates the discharge of coolant, promoting the flow of coolant within the cooling pipe 302, which in turn helps to cool the bellows. The support bracket 301 supports the bellows, facilitating heat exchange during support. The cover plate 202 is positioned at one end of the extruder 101, and the sealing ring 201 provides a sealing effect, allowing the insert block 205 to be inserted into the insert 206. Finally, the limit bolt 207 is threaded through the insert 206 for limiting, facilitating the removal of the screw conveyor 204 from the extruder 101, and thus facilitating cleaning and maintenance of the screw conveyor 204, ensuring its normal operation.

[0027] The heater 103, heating tube 104, tube wall forming mold 108, motor 109, motor 203, screw conveyor 204, cooling tube 302, and electric push rod 305 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the heater 103, heating tube 104, tube wall forming mold 108, motor 109, motor 203, screw conveyor 204, cooling tube 302, and electric push rod 305 will not be explained in detail.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
