The fan 285 is controlled to transport gas to the inner cavity of the processing chamber 28, and the electric heating wire 282 is controlled to heat the air. The hot air passes through the inner cavity of the hollow part 26 and the connecting hose 27, and is transported to the inner cavity of the hollow frame 25, and then output from the exhaust hole 251 and the inclined exhaust pipe 252, and is blown to the surface of the No. 1 machine cover mold 11 and the No. 2 machine cover mold 12, so as to increase the temperature inside the mold cavity, increase the fluidity of the material inside the mold cavity, reduce the generation rate of bubbles, and improve the production qualification rate of the main cover. The partition plate 281 can separate the inner cavity of the processing chamber 28 into an upper and lower part, and the lower part does not have the heating function.

[0023] As an implementation method in this embodiment, Figure 2 , Figure 4As shown, a first gate plate 283 located above the partition plate 281 is slidably connected to the inner wall of the processing chamber 28, and a second gate plate 284 located below the partition plate 281 is slidably connected to the inner wall of the processing chamber 28.

Through the design of the rubber support 13, the vibration can be absorbed to prevent the vibration from being transmitted to the bottom support platform 14 and affecting the stability of the mounting surface.

[0025] Working principle: When used in a low-temperature environment, the fan 285 is controlled in advance to deliver gas to the inner cavity of the processing chamber 28, and the electric heating wire 282 is turned on to heat the air. The hot air is then delivered to the inner cavity of the hollow frame 25, and then output from the exhaust hole 251 and the inclined exhaust pipe 252, and blown to the surface of the No. 1 machine cover mold 11 and the No. 2 machine cover mold 12 to increase the temperature inside the mold cavity. After the preheating is completed, injection molding can be performed in the mold cavity of the No. 1 machine cover mold 11 and the No. 2 machine cover mold 12. After the injection molding is completed and the material is cooled, the No. 1 machine cover mold 11 and the No. 2 machine cover mold 12 are separated to obtain the main cover of the pepper grinder.
