The present invention discloses a molding mold for a plastic hollow container extrusion blow molding machine, comprising an oral die and a core die arranged in the center of the oral die. The oral die comprises a die cylinder and an oral die body, a material storage cavity is arranged in the die cylinder, a push ring is vertically slidably mounted in the material storage cavity, and the oral die body is fixed at the lower end of the die head. The core die comprises a core die cylinder and a core die body, a push-pull rod is vertically slidably mounted in the inner cavity of the core die cylinder and driven by a push-pull power device, the core die body is fixedly mounted at the lower end of the push-pull rod, the core die body is in the shape of a conical table, an annular extrusion port is formed between the core die body and the oral die body, and a limiting device for limiting the upper and lower movement limits of the push-pull rod is arranged between the push-pull rod and the inner cavity of the core die cylinder. The gap between the core die and the oral die of the mold is adjustable, products produced by using the die head have reasonable thickness at each part and high yield, and the distance between the oral die and the core die is reasonably adjusted to avoid sudden changes.
