This application discloses a die head with an adjustable storage cavity structure for hollow blow molding machines, including a fixed plate, an outer mold body and a hollow lower nozzle. The outer mold body is fixedly installed under the fixed plate, and the lower nozzle is slidably sleeved on the lower outer wall of the outer mold body. An inner mold body and a core lifting rod driving vertical movement are arranged inside the outer mold body. The inner mold can move downward into the lower nozzle, forming an adjustable storage cavity between the outer wall of the inner mold assembly and the inner wall of the outer mold and lower nozzle. The sliding lower nozzle adjusts the cavity volume according to material consumption of different products, meeting diversified processing requirements. It eliminates repeated disassembly and assembly of die heads, improves work efficiency, and avoids quality defects such as material shortage and flow dead zones.
