[0024] ​The operator sets the inner core between the lower mold 100 and the upper mold 300, and ensures that the two molds are tightly buckled, then the external plastic raw material supply pipe is connected with the inlet of the feed three-way pipe 402 near the one-way valve 404, and then the external plastic raw material supply pipe supplies the raw material through the feed channel 401 to the space between the lower mold 100 and the upper mold 300, and the one-way valve 404 ensures that the raw material can only flow to the outlet of the feed channel 401 to prevent backflow. After the mold cavity is filled, the circular plate 400 is rotated synchronously, and the feed channel 401 in the circular plate 400 is rotated synchronously with the rotation of the circular plate 400. The outlet of the feed channel 401 is finally rotated out of the mold cavity of the upper mold 300, and at this time the circular plate 400 is in the same plane as the mold cavity of the upper mold 300, which ensures the integrity of the mold cavity of the upper mold 300 and the smoothness of the surface of the injection molded part at the breakage, so that the surface of the injection molded part does not have gate residues, and subsequent multiple repair processes are not required, which is beneficial to efficient and stable production of rubber roller shaping.
