The present invention discloses a continuous mixing and compression molding system comprising a twin-screw extruder and a compression molding apparatus. The compression molding apparatus includes a lower fixed mold and an upper movable mold. The bottom surface of the upper movable mold is provided with an upper mold cavity, and the top surface of the lower fixed mold is provided with an injection cavity. A melt continuous delivery mechanism is installed within the lower mold base. The melt continuous delivery mechanism comprises a melt delivery pipeline and a feed valve. The outlet of the twin-screw extruder is connected to the inlet of the melt delivery pipeline. The feed valve comprises a valve body and a valve stem. The valve body is fixed within the lower mold base. An inlet port is provided on the outer surface of the valve body, and an outlet port is provided at the top of the valve body, communicating with the injection cavity. The melt delivery pipeline communicates with the inlet port on the valve body. The valve stem is positioned within the valve body, with the gap between the valve stem and valve body forming the melt delivery channel. A valve plug is mounted on the upper end of the valve stem, while the lower end of the valve stem extends through the valve body and connects to drive mechanism A. This invention is suitable for online compression molding of thermoplastic resin systems with high melting points and rapid crystallization rates, enabling the formation of complex structural components while ensuring the integrity of the molded products.
