The utility model discloses an injection molding machine with a preheating function. The injection molding machine comprises an injection molding machine body and a lower mold mounted at the top end of the injection molding machine body, the first hydraulic cylinder is mounted on the inner side of the injection molding machine body, a sliding table is connected to the output end of the first hydraulic cylinder, an upper mold is mounted at the bottom end of the sliding table, a positioning rod is fixedly connected to the top end of the sliding table, and a movable seat is slidably connected to the outer wall of the positioning rod; and a preheating mechanism. According to the preheating mechanism, when raw materials are stacked in the feeding hopper and need to be preheated, an electric heating wire, a fan and a driving motor are started, the electric heating wire works to dissipate a large amount of heat, the heat is blown into a stirring rod through the fan, then the heat is sprayed into the feeding hopper t
