Chinese patent document CN201510853623.8 provides "A mold heating tube", including a metal body, the surface of the metal body is sintered with a protective layer, and the protective layer is composed of the following components by weight: 22 parts of petroleum resin, 3 to 4 parts of pentaerythritol, 2 to 3 parts of diethylene glycol butyl ether, 1 to 2 parts of nano-aluminum trioxide powder, 3 to 4 parts of fumed titanium dioxide, 4 to 5 parts of rosin maleic anhydride ester, and 2 to 3 parts of modified polybutadiene resin. The mold heating tube of the present invention has a high hardness, heat-resistant, anti-oxidation, corrosion-resistant and anti-scaling protective layer sintered on the surface of the metal body, which can increase the service life of the mold heating tube.

[0004] However, this technical solution still has shortcomings. This type of heating tube needs to be disassembled frequently due to working conditions. In actual applications, it is found that due to the use of a metal casing, the operating temperature of the heating tube is about 400°C, and the temperature of the tail end is about 200°C during disassembly. In addition, the tail end of the heating tube is not non-slip and not insulated, making disassembly very difficult. Utility Model Content
