Description of the Invention: [Technical Field] The present invention relates to an injection mold, and more particularly to an assembly method of an injection mold. [Prior Art] Referring to the third figure, a conventional injection mold 80 includes a movable mold 81 and a fixed mold 82. The movable mold 81 includes a movable mold fixing plate 811, a backing plate 812, a ejector plate 813, a thimble fixing plate 814, and a moving body. Template 815, thimble 816 and guide post 817. When the movable mold 81 is assembled, the ejector pin 816 is usually inserted into the ejector pin 813 and the ejector pin hole (not shown) of the movable die plate 815, and the thimble fixing plate 814 is fastened to the ejector pin plate 813 to prevent the ejector pin 816 from being ejected. Then, the guide post 817 is inserted into the movable platen 815, the ejector plate 813, the thimble fixing plate 814, and the movable mold fixing plate 811. However, in the assembly method of the above injection mold 80, the guide post 817 does not have accurate positioning before the thimble plate 813 and the ejector pin 816 are installed, and the installation of the guide post 817 is inserted into the movable template 815 and the ejector plate 813 by tapping. In the thimble fixing plate 814 and the movable mold fixing plate 811, during the assembly process, the guide post 817 causes the ejector pin 813 and the thimble fixing plate 814 to be warped and deformed due to elastic deformation, thereby causing the injection mold 80 to be installed horizontally due to ejection. The problem occurs in that the ejector plate 813 is unevenly deformed by the force, the thimble 816 is broken, and the returning is burned. In addition, the guide post 817 is usually disposed on the movable mold fixing plate 811 and the movable platen 815 in an interference fit manner, and the rear force caused by the repeated ejection and returning operations during the opening and closing of the mold of the mold 8G leads to the lead. The column 817 is loosened and then retracted.
