Full-closed-loop position accurate control electric injection molding machine

The utility model discloses a full-closed-loop position accurate control electric injection molding machine which comprises a machine base, a cooling assembly and a ventilation assembly. The injection molding machine has the beneficial effects that after injection molding is finished, a user starts the motor I between the two supporting plates to operate through the control button, the motor I operates to drive the rotating rod I to rotate, and the rotating rod I rotates to drive the fan blades to rotate, so that external air can be blown into the sealing cover of the injection molding machine to take away the temperature of the surface of a mold; and when a second filter plate is damaged, the second filter plate can be detached from the interior of an annular plate, the second filter plate can be conveniently replaced when being damaged, a first motor can drive a connecting rod to rotate while cooling is conducted, the connecting rod rotates to drive a rotating plate to rotate, and therefore cooling of the m
