The utility model relates to the technical field of blow molding die heads, in particular to an anti-falling structure and a multi-layer large-capacity HDPE civil barrel hollow blow molding die head, comprising: a fixed splint, one end of the fixed splint abuts against the surface of the hollow plastic body, the other end of the fixed splint is fixed with a fixed side plate, the top of the fixed side plate is fixed with a top plate, the hollow plastic body abuts against the surface of a movable splint, one end of the movable splint is fixed with a taper rod, the other end of the taper rod is movably inserted into a taper rod hole, the taper rod hole is formed on the surface of the fixed splint, the other end of the movable splint is fixed with a movable side plate, and a pull rod is fixed on the surface of the movable side plate. The beneficial effects are that: one end of the hollow plastic body sleeved on the blow molding head is clamped by the movable splint and the fixed splint, the friction force between them plays a role in preventing the hollow plastic body from falling off the surface of the blow molding head, and the taper rod also produces a limit effect with the through hole of the hollow plastic body, thereby further strengthening the anti-falling effect of the hollow plastic body.
