The mold for producing several color plastic baling bands simultaneously includes one mold body with several material inlets and material outlets; several main material feeding passages corresponding to the material inlets separately; several main discharge passages corresponding to the material outlets separately; and many shunt passages, with each main material feeding passage corresponding to several shunt passages. In the main material feeding passage and in the location near the material inlet, one regulating screw is mounted for regulating the size of the material inlet. The present invention has raised production efficiency and lowered production cost. |
