PROBLEM TO BE SOLVED: To improve a two stage injection molding machine so that plastic parts of different colors and different materials can be molded with one same injection molding machine. SOLUTION: This two stage injection molding machine comprises a fixed mold plate 11, a movable mold plate 13, an intermediate assembly 14 composed of two parts which is freely movably arranged between those plates, and an injection molding material feed means for the intermediate assembly 14 for feeding injection molding materials to stages 16, 17 formed between the intermediate assembly 14 and respective mold plates 11, 13. In order to simplify processing of injection molded parts of different colors by one same injection molding process, several feed means for feeding the injection molding material via respective main channels 21, 25 are provided to respective stages 16, 17. Thereby, in addition to free selection of color to each stage, plastics of various types can be used for each stage by one same injection molding process. |
