This utility model invention discloses a multi-layer extrusion blow molding machine die head, which includes a die head. The bottom end of the die head has an open structure, and equally spaced studs are screwed onto the outer edge of the top end of the die head in a circular arrangement. A horizontally positioned metal ring is screwed onto the top end of the studs. An electric heating sleeve is fitted onto the outer wall of the die head. A metal cylinder is rotatably connected to the inner wall of the top end of the die head, and a telescopic column is inserted into the inner wall of the metal cylinder. A driving mechanism is provided on the outer wall of the top end of the metal ring for driving the telescopic column to extend and retract and for rotating the metal cylinder. A discharge head is inserted into the bottom end of the inner wall of the die head, and the bottom end of the discharge head has a protruding part, and a conical groove communicating with the inside of the discharge head is opened at the bottom end of the protruding part. This utility model invention facilitates double-layer discharge and multi-layer extrusion. The combination of the discharge head, the liquid outlet holes on the telescopic column, and the conical groove and tapered part facilitates switching between inner and outer layer discharge, making control convenient and operation simple.
