The invention relates to the field of molds, and discloses a moving device for assisting quick assembly and disassembly of an injection mold. The moving device comprises a base; a first vertical plateand a second vertical plate respectively provided with a first sliding groove and a second sliding groove; a moving rod, wherein one end of the moving rod is in sliding connection with the first sliding groove through a first sliding block, the other end of the moving rod penetrates the second vertical plate to fix an upper mold of the injection mold, a second sliding block is arranged at the position whether the other end penetrates the second vertical plate, and the second sliding block is in sliding connection with the second sliding groove; a driving assembly used for driving the moving rod to move up or down; a limiting assembly used for limiting the driving assembly from moving. The upper mold of the injection mold is driven to move down or up by the mechanical structure, so that the process of automatic mold assembly or disassembly is achieved, the manual operation can be replaced, and the working efficiency is improved.
