In order to ensure that the position of the injection mold does not shift after opening and closing, a guide structure is generally designed, which is mainly composed of a guide column and a guide sleeve. However, the existing injection mold guide structure does not have a lubrication device, which will cause wear during use and affect the accuracy of the guide structure.

[0003] The prior art has the following defects or problems: The prior art publication number is: CN219505315U discloses an injection mold with a built-in plastic guide mechanism, including: an injection mold box, a lower mold arranged inside the injection mold box, an electric push rod arranged on the top of the lower mold, an upper mold provided at the bottom of the electric push rod for use with the lower mold, a guide assembly arranged between the upper mold and the lower mold, used to press the lower mold tightly, and a cooling assembly arranged inside the injection mold box near the bottom end.

[0004] During use, the above-mentioned equipment can firmly press the upper mold and the lower mold together through the guide component to prevent leakage between the lower mold and the upper mold, solve the problem of docking deviation caused by the lack of a guide positioning mechanism between the upper and lower molds, and cool the heat in the lower mold through the cooling component, so that the injection molded product in the lower mold can be quickly cooled and formed, which facilitates the demolding of the injection molded product and improves the efficiency of the injection molding work.

[0005] In actual use, the guide rod cannot be lubricated, and after the guide rod is in contact with air for a long time, impurities in the air are easily attached to the guide rod, affecting the use effect of the guide rod. Therefore, it is necessary to propose an injection mold with a built-in guide structure.

[0006] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0028] In this embodiment, the oil pump 9 extracts the lubricating oil from the oil storage tank 11 through the oil extraction pipe 12, and then introduces it into the interior of the connecting pipe 8 through the oil guide pipe 10, and finally distributes it from the connecting pipe 8 to each sliding sleeve 7. The sliding sleeve 7 slides on the outside of the guide column 6, so that the guide column 6 always maintains the lubrication effect, thereby improving the guiding lubrication and movement stability of the lower mold 3.

[0029] Example 2

[0030] like Figure 1-Figure 5As shown, a first elastic rubber sleeve 13 is fixedly connected between each first fixed block 4 and the inner wall of the injection mold box 1, and each first elastic rubber sleeve 13 is located outside the corresponding guide column 6. A second elastic rubber sleeve 14 is fixedly connected between each first fixed block 4 and the corresponding second fixed block 5, and each second elastic rubber sleeve 14 is located outside the corresponding guide column 6. A third elastic rubber sleeve 15 is fixedly connected between each second fixed block 5 and the inner wall of the injection mold box 1, and each third elastic rubber sleeve 15 is located outside the corresponding guide column 6.
