The novel rapid glue injection mechanism of a split type injection molding machine as claimed in claim 1, characterized in that: The glue melting power device is one of a direct-drive glue melting motor, a glue melting motor with an acceleration and reduction gear, a five-star oil motor, and a five-star oil motor with an acceleration and reduction gear.

8. The novel rapid glue injection mechanism of a split type injection molding machine as claimed in claim 1, characterized in that: The front plate of the injection head plate is provided with a first preset hole for the molten plasticizing component to pass through, and the rear plate of the injection head plate is provided with a second preset hole for the injection piston rod of the injection driving mechanism to pass through.

9. The novel rapid glue injection mechanism of a split type injection molding machine as claimed in claim 1, characterized in that: A glue injection mold bracket is arranged on the side of the glue injection head plate away from the glue injection driving mechanism, and the glue injection mold bracket includes a mold bracket slidably mounted on a work platform or the ground, and a hydraulic cylinder arranged between the mold bracket and the glue injection head plate. The mold bracket is provided with a hole for the molten glue plasticizing component to pass through, and the central axis of the hydraulic cylinder transmission shaft is arranged parallel to the central axis of the molten glue plasticizing component.
