Abstract

The invention discloses a plum-blossom tube mandrel, which comprises a hollow cylinder (8), which is connected to a plug (4) through a connecting rod (5); the plug (4) is provided with a groove (2) in the circumferential direction, A sealing ring (3) is provided in the groove (2), and the outer diameter of the plug (4) is equal to that of the hollow cylinder (8); the end of the hollow cylinder (8) connected to the connecting rod (5) is provided with a water outlet hole (6), the other end is provided with a water injection hole (9); the outer wall of the hollow cylinder (8) is provided with a water outlet (7), and the water outlet (7) is a spiral groove, and a small water outlet hole (10) is arranged on the spiral groove . The invention completely changes the cooling method in the process of plum-blossom tube processing. In addition to injecting water into the inner surface of the plum-blossom tube mandrel that is conventionally used, it also injects water into the inner surface of the plum-blossom tube for cooling, which greatly reduces the cooling time required for the plum-blossom tube forming, thereby greatly Improve processing speed.

Description

technical field [0001] The invention relates to the technical field of plastic machinery, in particular to a plum blossom tube mold. Background technique [0002] The plum blossom tube is mainly used as a communication cable sheath tube. This kind of tube has a smooth inner wall and can directly pass through the optical cable, which can save man-hours. The processing method of the plum blossom pipe is to use the pipe extruder and the plum blossom pipe mold to extrude. like figure 1 , the commonly used plum blossom tube mold includes a base and a plum blossom tube mandrel evenly distributed on the base. Slower, so the processing speed must be reduced to ensure the quality of the finished product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plum-blossom tube mandrel, which can greatly increase the production speed, so as to overcome the deficiencies in the prior art. [0004] The technical scheme of the p...
