ABSTRACT:
A device includes a sliding base, supporting posts, and hydraulic oil; the sliding base has cavities, an oil passage communicating with the cavities, and oil seals secured around respective cavities, and it is movable along a guide rail secured on a bed of an injection molding machine; the supporting posts each have a room on a lower end, and are inserted in respective cavities such that the rooms communicate with the cavities; the posts touch and prop a movable wall of the molding machine at upper ends, which wall is supported by and movable along guide rods, and has bushings around the guide rods; the hydraulic oil is injected into the sliding base and the posts until the axes of each bushing and the corresponding guide rod are aligned; thus, alignment of the axes of each bushing and the corresponding guide rod will be maintained when the movable wall is moving.
