This utility model discloses a storage type machine head for an extrusion blow molding machine, comprising a storage core extending in the vertical direction, an intermediate ring coaxially and fixedly sleeved on the outer side of the storage core, a storage cylinder coaxially sleeved on the outer side of the intermediate ring, and an extrusion mold fixedly arranged on the storage cylinder coaxially.
A runner structure is arranged between the intermediate ring and the storage core; a feed inlet is formed on the storage cylinder, a storage cavity is arranged between the storage cylinder and the storage core, and the storage cavity is located at the lower side of the runner structure.
The feed inlet, the runner structure, the storage cavity and the extrusion mold are in communication in sequence.
The runner structure includes multi-stage shunt runners extending from top to bottom and in communication stage by stage; each stage of shunt runners is provided in a number, and the multiple shunt runners are arranged in an array along the circumferential direction of the storage core.
The depth of the next stage of shunt runners between two adjacent stages of shunt runners is smaller than that of the previous stage, and the next stage of shunt runners and the previous stage of shunt runners have a gradually shallowing depth at their mutual communication position.
