The present utility model relates to a two‑color extrusion blow molding machine with arbitrarily variable size, comprising a frame, an extrusion head, two variable modules and two conveying screws. The extrusion head is mounted on the frame, the two variable modules are correspondingly and slidably mounted in the frame, a driving motor for driving the two variable modules to move toward each other is arranged on the frame, and the two conveying screws are mounted on the frame. A partition plate is installed in the extrusion head, which divides the extrusion head into two extrusion chambers with the same volume, and the two extrusion chambers are symmetrically arranged. When performing extrusion blow molding, materials of different colors are placed in the two conveying screws, and the materials in the two conveying screws are respectively conveyed into the extrusion chambers. Then the materials in the extrusion chambers move toward the outlet of the extrusion head and converge to form a two‑color material, which is then stamped and extrusion‑blown in the two variable modules to form a two‑color product, realizing two‑color extrusion and expanding the application scope.
