Figure 1 shows the principle of double color injection molding. The utility model has two material cylinders, each of which has the same structure and use as the ordinary injection molding barrel. Each cylinder has its own channel connected with the nozzle, and the nozzle path is also equipped with the valve 2,4. When the melted material is plasticized in the barrel, the sequence of the material entering into the nozzle and the proportion of the discharge material are controlled by the opening and closing valves 2 and 4, and then injected into the cavity by the nozzle. Various plastic products with different color blending effects can be obtained.
