The key points of its technical solution include an operating platform, and the top of the operating platform is provided with a molding upper mold, a molding lower mold, a telescopic support device, a silicone liquid stirring device, a silicone liquid extrusion device, and a liquid cooling and cooling circulation device. The molding upper mold is arranged directly above the molding lower mold, and the silicone liquid stirring device and the silicone liquid extrusion device are both located directly above the molding upper mold.
