[0015] Working principle: the cylinder is controlled by a built-in one-way valve and a discharge one-way valve. Material is extruded when the shaft moves up and down. The cylinder is under high pressure, and the output continuous pressure is stable, with small fluctuations and stable flow. When the shaft moves upward, the built-in one-way valve in the cylinder is opened, and the material enters the lower pump body 7 and the middle pump body 6 of the cylinder through the piston production plate 9 and the piston plate 8 to supplement the material. The material is extruded into the pipeline through the built-in one-way valve and the discharge one-way valve. When the shaft moves downward, the built-in one-way valve in the cylinder is closed, and the material in the middle pump body 6 of the cylinder is directly extruded into the pipeline through the external one-way valve. The material passes through the pipeline, the mixing block, and the static mixer to mix evenly, enters the mold, and is heated and vulcanized.
