[0026] This utility model provides a technical solution: such as Figure 1 As shown in this embodiment, an anti-stick hot press plate includes a lower press plate 1, and an upper press plate 2 is bolted to the upper end of the lower press plate 1. The lower press plate 1 and the lower press plate 2 are made of aluminum alloy.

[0027] like Figure 2 and Figure 4As shown, the upper surface of the upper pressure plate 2 is provided with an array of micro-protrusions 21. The micro-protrusions 21 are formed by machining. Several micro-protrusions 21 are provided on the upper surface of the upper pressure plate 2. The outer surface of the upper pressure plate 2 is coated with an anti-stick coating, and the surface of the micro-protrusions 21 is coated with a hydrophobic coating. The anti-stick coating is a KNM1000 anti-stick coating, and the hydrophobic coating is a ceramic coating. The height of the micro-protrusions 21 is 0.1-0.5 mm, and the spacing is 0.5-1 mm. A heat insulation layer 24 is provided around the bottom of the upper pressure plate 2. The heat insulation layer 24 can reduce heat loss. To improve efficiency, a heating plate 22 is provided inside the heat insulation layer 24.

A heating tube 23 is embedded in the heating plate 22. The heating tube 23 can convert electrical energy into heat energy. The heating tube 23 has a U-shaped design. Through the combined action of the micro protrusions 21, hydrophobic coating and anti-stick coating, the adhesion of materials is reduced. The micro protrusions 21 can evenly distribute heat on the hot press plate, improving the quality of hot pressing.

[0028] like Figure 2 and Figure 3 As shown, a heat-conducting plate 3 is provided on the bottom side of the lower pressure plate 1. A serpentine heat-conducting groove 31 is formed on one end face of the heat-conducting plate 3, and a serpentine heat-conducting groove 32 is formed on the other end face of the heat-conducting plate 3. A serpentine cooling pipe 34 is provided on the serpentine heat-conducting groove 31. An inlet pipe 341 is provided on one end of the serpentine cooling pipe 34, which passes through one end of the lower pressure plate 1.
