Description

Technical Field

[0001] The utility model belongs to the technical field of PE pipe production, and relates to an extrusion molding device, in particular to a PE water supply pipe extrusion molding device. Background Art

[0002] PE pipes are one of the most common pipes. They have the advantages of low-temperature impact resistance, chemical corrosion resistance, and wear resistance. They are widely used in water supply, drainage, heating, gas supply, agricultural irrigation, water conservancy projects, and various industrial installations. Polyethylene is a typical thermoplastic plastic. Due to its odorless, tasteless, and non-toxic characteristics, it is promoted and popularized.

[0003] After searching, it is found that Chinese patent documents disclose an extrusion molding device for the production of PE water supply pipes [Application number: 202120951054.1; Publication number: CN 214562828 U]. An extrusion molding device for the production of PE water supply pipes includes a bottom plate, a support plate is fixed on the top of the bottom plate, an extrusion barrel is installed on the top of the support plate, a hot melt box is installed inside the extrusion barrel, an extrusion plate is installed inside the hot melt box, a sliding sleeve is installed on the surface of the extrusion plate, a mounting block is fixed inside the sliding sleeve, and a mounting groove is opened on the surface of the extrusion plate. The raw material is extruded through friction contact between the sliding sleeve and the extrusion barrel or the hot melt box. The sliding sleeve and the extrusion plate are detachably connected, which is convenient for replacement and saves resources. During the process of extruding the raw materials on the extrusion plate, the stirring rod rotates to stir the raw materials to ensure that the raw materials are fully mixed. When the extrusion plate returns, the raw materials carried on the back are discharged from the extrusion barrel through the discharge pipe to ensure that the extrusion plate returns to its original position.

[0004] Although the patent stirs the raw materials to ensure that the raw materials are fully mixed, when the extrusion plate returns, the raw materials carried on the back are discharged from the extrusion barrel through the discharge pipe to ensure that the extrusion plate returns to its original position. However, the patent simply extrude the raw materials and wait for the raw materials to cool naturally to form a PE water supply pipe. This method cannot plasticize the PE water supply pipe, resulting in a low yield rate, and the waiting time for natural cooling is long, resulting in low molding efficiency. Utility Model Content
