Aerogel heat shield of injection molding machine

The utility model discloses an aerogel heat insulation cover of an injection molding machine, which comprises a heat insulation cover body, wherein the whole heat insulation cover body is annular, and the heat insulation cover body has elasticity; the fixing pipe is arranged at one end of the heat insulation cover body, the inner diameter of the fixing pipe is the same as that of the heat insulation cover body, and the outer diameter of the fixing pipe is smaller than that of the heat insulation cover body; the connecting layers are arranged on the side face of the heat insulation cover body, and the multiple connecting layers are arranged on the side face of the heat insulation cover body. When the aerogel heat shield for the injection molding machine is used, the heat preservation layer can preserve heat of the injection molding machine, so that heat of the injection molding machine is prevented from being transmitted to the outside, the aerogel layer can also play a role in heat preservation and heat insul
