[0043] The water inlet 24 is used for flowing the liquid at a preset temperature into the outer wall of the rubber flow channel 21 of the barrel 2 to soften the rubber, and then the softened rubber is subjected to a constant temperature treatment, so that the rubber in the rubber flow channel 21 is always in a softened state, and then the water outlet 25 is used for returning the water outside the barrel 2 to the water temperature control device to be heated to the preset temperature, and the cycle is repeated, so that the rubber in the rubber flow channel 21 is always in a softened state, thereby preventing the rubber from hardening and being continuously injected into the mold through the conveying screw in the rubber flow channel 21.

[0044] In summary, the screw rotating driving device drives the left rubber extruding screw and the right rubber extruding screw to rotate forward or reverse respectively, and the rotation pressure generated by the rotation of the left rubber extruding screw and the right rubber extruding screw can extrude the rubber to the center and into the discharge, so that the rubber can better enter the barrel, the rubber extrusion and mixing and smooth discharge can be realized, the rubber blockage is effectively avoided, and the rubber discharge efficiency and continuity are improved.
