Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine accessories, and more specifically, to a mold adjusting nut. Background Art

[0002] In an injection molding machine, four guide columns, also known as "Guling columns", need to be set between the movable platen and the fixed platen of the injection molding machine. During operation, the movable platen is pulled to move by the four guide columns. The outer surfaces of the four guide columns are provided with threads, and the outside of each guide column needs to be threadedly connected to a mold adjusting nut. The difference between the mold adjusting thread and the traditional nut is that a gear is set on the outside of the mold adjusting nut, and the gear is driven to rotate by an external power device, so that the gear drives the mold adjusting nut to rotate, and the mold adjusting nut cooperates with the thread of the guide column to drive the guide column to move, thereby making the movable platen of the injection molding machine work.

[0003] However, the mold adjusting nut of a traditional injection molding machine is in direct contact with the limit frame of the injection molding machine. The limit frame is used to limit the mold adjusting nut so that it can only rotate but not move. Therefore, there will be a large friction between the mold adjusting nut and the limit frame of the injection molding machine. Long-term use will cause the mold adjusting nut to be severely worn, which is not conducive to the service life of the mold adjusting nut. Therefore, in view of the above problem, a mold adjusting nut is specially proposed. Utility Model Content
