The present utility model discloses a mold moving mechanism for an accumulator-type hollow blow molding machine, comprising a base, linear guide rails, a front mold frame, a rear mold frame, a base frame, a hydraulic cylinder and a frame shaft. A synchronization mechanism is arranged on two linear guide rails between the rear mold frame and the base frame, a synchronization gear box is arranged on the top surface of the synchronization frame, a gear with a horizontal axis is arranged in the synchronization gear box, a first synchronization rack and a second synchronization rack are matched on the gear, and a synchronization hydraulic cylinder is connected between the synchronization frame and a cross beam on the base frame side. By installing a synchronization mechanism between the rear mold frame and the base frame, and arranging a synchronization hydraulic cylinder between the synchronization frame of the synchronization mechanism and the cross beam on the base frame side of the base, the original displacement extrusion device and accumulator die head are changed into a displacement mold moving mechanism, which is more stable and efficient, realizes mold hoisting without displacing the extrusion device and accumulator die head, and avoids problems such as large vibration and poor precision caused by displacing the extrusion device and accumulator die head.
