Description

Technical Field

[0002] At present, in the process of processing plastic pipes, pipe extrusion dies are mainly used for processing and forming.

[0003] After searching, according to the patent number "CN215550737U", a pipe extrusion die with a cooling structure is disclosed, including a die base, a processing groove is opened in the middle position of the upper edge of one side of the outer wall of the die base, a metal die-casting pipe is fixed in the middle position of one side of the inner wall of the processing groove, and a first slide groove is opened at the upper and lower ends of one side of the inner wall of the processing groove. The pipe extrusion die with a cooling structure uses a driving device to dynamically extrude the metal extrusion strip, so that the die-casting structure extrude the raw materials in the processing groove, connects the butt-joint pipes at both ends with external water pipes, and allows the cold water to flow and circulate in the connected water pipes. While flowing, the formed pipe in the upper processing groove can be cooled and shaped, thereby accelerating the cooling speed of the pipe.

[0004] The above-mentioned pipe cooling structure mainly dissipates heat through water circulation to improve the heat dissipation efficiency. However, during the heat dissipation process, the water temperature will gradually rise as it circulates. When it flows to the tail end, the water temperature is too high, which affects the heat dissipation efficiency and thus affects the processing efficiency of the pipe. For this reason, we designed a guide cooling device and its pipe extrusion die to solve the two-handed technical problem. Utility Model Content
