The base plate is provided with a plurality of placement columns, in which placement holes for placing nuts are formed. A push plate is provided between the top plate and the base plate, and a plurality of push rods for pushing the nuts out are provided on the push plate. A driving cylinder is provided on the top plate, and a piston rod of the driving cylinder is connected to the push plate. When the driving cylinder is in an initial position, the front end of the push rod is located at the rear end of the placement hole.

[0006] Preferably, a plurality of connection blocks are provided at the bottom of the top plate and the bottom plate, and positioning columns are provided on the connection blocks.

[0007] Preferably, a guard plate is also provided at the bottom of the top plate and the bottom plate.

[0009] The utility model also provides an injection mold, which uses the above-mentioned injection mold nut placement jig and also includes an upper mold and a lower mold, and the lower mold is provided with a side mold core for receiving the nut.

[0010] Preferably, a nut placement position corresponding to the nut is formed on the side mold core, and a limiting column for limiting the nut is provided on the nut placement position.

[0011] Preferably, the lower mold is provided with a positioning hole corresponding to the positioning column.

[0012] Compared with the prior art, the utility model has the following beneficial effects: by providing a jig, the nuts can be arranged outside the mold first, and then the nuts are placed in the mold as a whole, and then the cylinder is started to push the arranged nuts into the mold. This can make the placement depth of the nuts uniform, improve production efficiency, and optimize the multi-nut modling cycle. The inventor's experiments show that the comprehensive yield is increased by 30% and the cycle is saved by 30-40 seconds.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 6 In the embodiment of the utility model, the nut placing jig of the injection mold comprises a bottom plate 1 and a top plate 2 which are arranged at intervals, and a block 3 of equal height connecting the top plate 2 and the bottom plate 1. The bottom plate 1 is provided with a plurality of placing columns 4, and a placing hole 5 for placing nuts is formed in the placing columns 4. A push plate 6 is provided between the top plate 2 and the bottom plate 1, and a plurality of push rods 7 for pushing out nuts are provided on the push plate 6. A driving cylinder 8 is provided on the top plate 2, and a piston rod of the driving cylinder 8 is connected to the push plate 6. When the driving cylinder 8 is in the initial position, the front end of the push rod 7 is located at the placing position. The rear end of the placement hole 5; when in use, the nut is manually placed in the placement hole 5, and then the entire jig is placed in the mold, aligned with the position where the nut is placed, and the cylinder is started. The cylinder pushes the push plate 6, and the push plate 6 pushes the nut into the mold through the push rod 7. It should be noted that the module itself has a position for placing the nut, and the mold can accommodate the jig. In addition, it should be noted that in order to prevent the nut from falling during the movement, a magnet ring can be set at the inner end of the prevention hole to absorb the nut. After the cylinder is started, the nut can be separated from the magnetic ring.

[0024] On some products, nuts need to be set in the product by injection molding in advance. In the past, the nuts needed to be manually placed into the mold one by one for arrangement. In this way, it was necessary to wait until the mold was opened and the molded product was taken out before the nuts could be placed into the mold one by one. This took a long time and was not easy to align in the mold.

[0025] To this end, the utility model provides a jig, which can arrange the nuts outside the mold first, then put the nuts into the mold, and then start the cylinder to push the arranged nuts into the mold. This can make the placement depth of the nuts uniform, improve production efficiency, and optimize the multi-nut modling cycle. The inventor's experiments show that the overall yield is increased by 30% and the cycle is saved by 30-40 seconds.

[0026] Furthermore, a plurality of connecting blocks 9 are provided at the bottom of the top plate 2 and the bottom plate 1, and positioning posts 10 are provided on the connecting blocks 9. After the positioning posts 10 are provided, positioning in the mold can be facilitated, thereby improving the working speed.

[0027] Furthermore, a guard plate 11 is provided at the bottom of the top plate 2 and the bottom plate 1. The guard plate 11 can protect the mold to prevent the bottom of the jig from crushing the mold after the jig is placed therein.

[0028] Furthermore, a plurality of grip holes 12 are provided on the bottom plate 1, and by providing the grip holes 12, the entire fixture can be easily lifted.

[0029] The utility model also provides an injection mold, which uses the above-mentioned injection mold nut placement jig, and also includes an upper mold 13 and a lower mold 14. The lower mold 14 is provided with a side mold core 15 for receiving the nut, and a nut placement position corresponding to the nut is formed on the side mold core 15. The nut placement position is provided with a limiting column 16 for limiting the nut; when working, the injection mold nut placement jig drives the cylinder 8 to push the nut into the limiting column 16. In the injection mold of the present application, by using the above-mentioned injection mold nut placement jig, the production efficiency can be improved, and the multi-nut modling cycle can be optimized. The inventor's experiment shows that the comprehensive yield is improved by 30% and the cycle is saved by 30-40 seconds.

[0030] Furthermore, the lower mold 14 is provided with a positioning hole 17 corresponding to the positioning column 10 .

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
