Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] Please refer to Figures 1-5 , the embodiment of the present utility model provides a mold for processing arc bullet steel cores, including a base 1, a lower mold 6 and an upper mold 9. An installation frame 7 is fixedly installed at the upper end of the base 1. The upper mold 9 and the lower mold 6 are both arranged inside the installation frame 7. The lower mold 6 is fixedly installed on the top surface of the base 1. A first cylinder 8 is fixedly installed at the upper end of the installation frame 7. The output shaft of the first cylinder 8 is fixedly connected to the top surface of the upper mold 9 through the inside of the installation frame 7. A fixing plate 10 is fixedly installed on the upper right side of the base 1. A second cylinder 11 is fixedly installed on the left side wall of the fixing plate 10. A reset groove 13 is arranged inside the right side of the fixing plate 10. An L-shaped push plate 14 is slidably connected inside the reset groove 13. The output shaft of the second cylinder 11 is fixedly connected to the left side wall of the L-shaped push plate 14 through the inside of the fixing plate 10. The bottom surface of the L-shaped push plate 14 is slidably connected to the top surface of the lower mold 6. After the bullet steel core stamping is completed, the first cylinder 8 is closed to move the upper mold 9 upward, and the second cylinder 11 is opened to move the L-shaped push plate 14 to the right, which can conveniently push the bullet steel core so that the bullet steel core is pushed out of the inside of the lower mold 6. A protective frame 5 is fixedly installed at the upper end of the base 1. A discharge hole 12 is arranged inside the base 1. The protective frame 5 is arranged at the upper end of the discharge hole 12. The discharge hole 12 is arranged on the right side of the lower mold 6, and the side walls of the protective frame 5 are closely attached to the side walls of the lower mold 6. The pushed bullet steel core will fall into the inside of the discharge hole 12. At this time, a collection box is placed below the discharge hole 12, which can facilitate the collection of the bullet steel core.

[0021] Embodiment 2

[0022] In this embodiment, as Figures 1-5As shown in the figure, a first cavity 15 and a second cavity 16 are respectively arranged inside the lower die 6 and the upper die 9. The size of the second cavity 16 is larger than that of the first cavity 15. Since the shape of the bullet steel core is symmetrical, when the bullet steel core is processed and the second cavity 16 is larger than the first cavity 15, most of the positions of the bullet steel core will leak out of the inside of the first cavity 15. The length of the lower die 6 is greater than that of the upper die 9, and the left side walls of the lower die 6 and the upper die 9 are both horizontal, which is convenient for pushing them with an L-shaped push plate. A fixed seat 2 is fixedly installed at the upper end of the base 1. A hydraulic cylinder 3 is fixedly installed inside the left side wall of the fixed seat 2. The output shaft of the hydraulic cylinder 3 is fixedly installed with a stamping head 4, and the fixed seat 2 is arranged on the right side of the lower die 6.

[0023] It should be noted that in this embodiment, when using the die for processing the arc-shaped bullet steel core, as Figures 1-5 shown in the figure, when stamping the bullet steel core, first place the bullet steel core in the first cavity 15 on the right side of the lower die 6, then turn on the first cylinder 8 to press the upper die 9 downward, and then turn on the hydraulic cylinder 3 to make the stamping head 4 perform stamping work on the placed bullet steel core material. After the bullet steel core is stamped, turn off the first cylinder 8 to move the upper die 9 upward, and turn on the second cylinder 11 to move the L-shaped push plate 14 to the right, which can conveniently push the bullet steel core and make the bullet steel core be pushed out of the inside of the lower die 6. The pushed bullet steel core will fall into the inside of the discharge hole 12. At this time, place a collection box below the discharge hole 12, which can facilitate the collection of the bullet steel core. Since the sizes of the first cavity 15 and the second cavity 16 are different, most of the positions of the bullet steel core will leak out of the inside of the first cavity 15, which is convenient for pushing it with an L-shaped push plate.
