Disclosed are a novel screw type low-pressure injection molding machine and injection molding method thereof. An outer wall of a cylinder is provided with a heating body thereon, and an upper end of the cylinder is sealedly connected to an upper sealing base. A side wall of the upper sealing base is in communication with a material cylinder, and a sealing opening at an upper end of the upper sealing base is provided with a screw therein. An upper end of the screw is connected to and driven by a driving rotation device, and a lower end of the screw extends into a lower end of the cylinder; the lower end of the cylinder is sealedly connected to a heating device, and is in communication with an adhesive accommodating space formed in the heating device. A side of the heating device is provided with a first pressure sensor, and an acquisition end of the first pressure sensor extends into the adhesive accommodating space. The embodiment of the present invention detects pressure within the adhesive accommodating space by the first pressure sensor, feeds and stops feeding materials to prevent a remaining adhesive material within the adhesive accommodating space from being carbonized due to being in a high temperature environment for a long period of time, thus delaying adhesive material carbonization time, and addressing an adhesive material carbonization problem, and avoiding a shutdown due to not feeding materials in time. |
