The utility model belongs to the technical field of blow molding machines, and specifically discloses a die mechanism of a blow molding machine. The die mechanism comprises a die core, a die ring, a die sleeve and a driving mechanism for driving the die core to move up and down; the die ring is fixedly connected with the die sleeve, and the die core is arranged in the die sleeve; an elliptical material channel is formed between the die core and the die ring. By designing the material channel between the die core and the die ring of the die mechanism to be elliptical, the extruded parison is elliptical when extruded downward through the die mechanism. When such a parison is sent to a mold clamping mechanism for clamping, the wall thickness of the molded hollow bottle is uniform without uneven thickness, avoiding waste of raw materials and saving costs.
