[0021] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0022] As Figures 1-5 shown, a nut installation jig suitable for mold nut installation includes a nut feeding device and an auxiliary loading device. The nut feeding device includes a mounting frame, and a nut loading sleeve 6 and a telescopic driving device 4 are provided on the mounting frame. Among them, the mounting frame includes a base 1 and a fixing plate 2. Both the base 1 and the fixing plate 2 are rectangular plate-like structures, and the base 1 and the fixing plate 2 are parallel. The base 1 and the fixing plate 2 are connected by support columns 3. There are four support columns 3. The telescopic driving device 4 is arranged on the base 1, and the nut loading sleeve 6 is arranged on the fixing plate 2.

[0023] A nut loading hole 13 is provided on the nut loading sleeve 6. The nut loading hole 13 penetrates through both ends of the nut loading sleeve 6, and the nut loading hole 13 matches the outer cross-section of the nut 15. A nut ejector rod 11 is connected to the telescopic driving device 4, and the nut ejector rod 11 extends into the nut loading hole 13. The telescopic driving device 4 drives the nut ejector rod 11 to move in the nut loading hole 13. In this embodiment, the telescopic driving device 4 is a cylinder. A nut ejector rod connecting block 5 is provided at the front end of the output shaft of the cylinder, and one end of the nut ejector rod 11 is connected to the nut ejector rod connecting block 5.

[0024] The nut loading sleeve 6 is provided with a nut fixing mechanism. Specifically, the nut fixing mechanism includes steel ball holes provided on the nut loading sleeve, the steel ball holes are located on both sides of the nut loading hole 13, and steel balls 14 are installed in the steel ball holes. Among them, the steel ball holes are tapered holes, the aperture of the steel ball hole near the nut loading hole 13 is smaller than that of the other end, and the aperture of the steel ball hole near the nut loading hole 13 is smaller than the diameter of the steel ball 14. An elastic rubber sleeve 7 is sleeved outside the nut loading sleeve 6. The elastic rubber sleeve 7 is made of an elastic material. In this embodiment, the elastic rubber sleeve 7 is made of rubber. After the nut 15 is loaded into the nut loading hole 13, one side of the steel ball 14 contacts the inner side of the elastic rubber sleeve 7, and the other side of the steel ball 14 presses against the nut 15. Through the pressing force of the steel ball on the nut 15, the nut is effectively fixed in the nut loading hole 13 to prevent the nut from falling out.

[0025] The auxiliary loading device includes a bottom plate 9, and a nut sleeve rod 12 corresponding to the nut loading sleeve is provided on the bottom plate 9. A guide post 8 is provided on the fixing plate 2, and a guide hole 10 corresponding to the guide post 8 is provided on the bottom plate 9.

[0026] In the present utility model, the nut feeding device is used to place nuts on the injection mold, and the auxiliary loading device is used to load nuts into the nut loading sleeve on the nut feeding device. The nut feeding device is installed on the moving platform, and with the help of the moving platform, the nut feeding device can move between the injection mold and the auxiliary loading device. The specific usage method is as follows: Before the injection mold is opened, first put the nut on the nut sleeve rod 12 of the auxiliary loading device. The nut feeding device moves to a position directly opposite the auxiliary loading device. At this time, the nut sleeve rod on the auxiliary loading device corresponds to the nut loading sleeve on the nut feeding device. Then, under the action of the moving platform, the nut feeding device approaches the auxiliary loading device. At this time, the guide post on the nut feeding device is inserted into the guide hole on the auxiliary loading device, and the nut sleeved on the nut sleeve rod is sent into the nut loading hole. After the nut enters the nut loading hole, under the action of the elastic rubber sleeve, the steel ball presses against the nut, thereby temporarily fixing the nut in the nut loading hole. See the appendix Figure 5 ; Then the nut feeding device moves away from the auxiliary loading device and moves to a position directly opposite the injection mold under the action of the moving platform, and aligns the nut loading sleeve with the nut placement position on the injection mold. Then the nut feeding device gradually approaches the injection mold. At the same time, the guide post on the nut feeding device is inserted into the corresponding guide hole on the injection mold to position the nut feeding device. The telescopic driving device drives the nut ejector rod to move, and ejects the nut in the nut loading hole. The ejected nut just falls into the nut placement position on the injection mold, thus completing the feeding of the nut. After the feeding is completed, the nut feeding device leaves the injection mold, and the injection mold is closed and injection molding operation is carried out.

[0027] With this device, the operator only needs to place the nut on the nut sleeve rod of the auxiliary loading device, which is set at a position far from the injection mold, avoiding the risk of scalding caused by the operator directly placing the nut on the injection mold.

[0028] The present utility model is not limited to the above-mentioned optimal implementation manner. Any person can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to the present application, it falls within the protection scope of the present utility model.
