The invention discloses a blow molding machine die mechanism capable of eliminating burrs on small-caliber plastic bottles, including an annular die body and a die core arranged inside the body. The top of the die core is fixedly connected to the cylinder rod of a hydraulic cylinder for vertical driven movement. The bottom of the annular die body is provided with a conical outlet, and the lower section of the die core is designed with a conical segment. An outward-flaring annular hollow flow channel is formed between the outer conical surface of the core segment and the inner conical surface of the outlet. The bottom diameter of the die core is defined as b = a + 0.5~0.8mm, where a refers to the caliber of the processed small-caliber bottle. The mechanism is easy to manufacture, thoroughly eliminates surface burrs of small-caliber blow-molded products, and brings no extra production cost to enterprises.
