[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: a stable injection mold, comprising: a supporting base frame 1; a fixed mold 2 fixedly installed on the top of the supporting base frame 1; a movable mold 3 slidably disposed on the top of the supporting base frame 1; an inner top seat 7 slidably disposed inside the movable mold 3, a sliding top post 6 fixedly connected to one side of the inner top seat 7, the sliding top post 6 being slidably connected to the movable mold 3, and a plurality of ejector pins 8 fixedly connected to one side of the inner top seat 7, the ejector pins 8 being slidably connected to the movable mold 3; a fixed top plate 11 fixedly connected to one end of the sliding top post 6; and a reset part placed on the movable mold 3. On one side of mold 3, the fixed top plate 11 is connected to the reset part; the connecting plate 18 is placed above the support base 1, and the connecting plate 18 cooperates with the fixed top plate 11; the side fixed brackets 15 are symmetrically installed on the outside of the moving mold 3 by bolts, and a fixed support plate 16 is fixedly connected to one side of the side fixed brackets 15, and the fixed support plate 16 is slidably connected to the support base 1; the connecting side frame 19 is fixedly connected to one side of the support base 1, and a cylinder 20 is installed on one side of the connecting side frame 19, and the output end of the cylinder 20 is fixedly connected to the fixed support plate 16.

[0028] It should be noted that in this embodiment, the output end of the cylinder 20 drives the fixed support plate 16, the side fixed bracket 15, and the moving mold 3 to move on the support base frame 1. The guide sleeve 5 inside the moving mold 3 cooperates with the guide rod 4 on one side of the fixed mold 2 to guide the moving mold 3 to move. The moving mold 3 is injected into the fixed mold 2 and the moving mold 3 through the injection channel 25 and the injection port 24. The injection plastic is formed in the fixed mold 2 and the moving mold 3. After the molded workpiece needs to be removed, the output end of the cylinder 20 pulls the fixed support plate 16, the side fixed bracket 15, and the moving mold 3 to slide on the support base frame 1. The moving mold 3 drives the bottom limit slider 22 to slide and limit the support base frame 1. The bottom limit slider 22 slides and limits the limit outside the limit rod 23. When the moving mold 3 moves, it drives the inner top seat 7, the sliding top column 6, and the fixed top plate 11 to move. The fixed top plate 11 pushes against the connecting plate. On one side of 18, the output end of cylinder 20 continues to drive the fixed support plate 16, side fixed bracket 15 and moving mold 3 to move. When the fixed top plate 11 moves, it drives the sliding top column 6 and the limiting column 13 to move synchronously. The limiting column 13 slides in the fixed sleeve 12 and presses the second spring 14 in the fixed sleeve 12. The sliding top column 6 drives the inner top seat 7 and the ejector pin 8 to move. The ejector pin 8 ejects the molded workpiece. The inner top seat 7 slides on the outside of the limiting slide column 9 and presses the first spring 10. When the fixed mold 2 and the moving mold 3 are combined, the first spring 10 will return to its original position. At the same time, the second spring 14 will also return to its original position. The inner top seat 7, the sliding top column 6, the fixed top plate 11 and the limiting column 13 will return to their original positions. Each ejector pin 8 on one side of the inner top seat 7 will also return to its original position. The next injection molding operation is completed through the fixed mold 2 and the moving mold 3.

[0029] In one embodiment, such as Figure 1 and Figure 4 As shown, the reset part includes a fixed sleeve 12, which is symmetrically fixed to one side of the moving mold 3. A limit post 13 is slidably arranged inside the fixed sleeve 12. One end of the limit post 13 is fixed to the fixed top plate 11. A second spring 14 is arranged inside the fixed sleeve 12. One end of the second spring 14 is connected to the fixed sleeve 12, and the other end of the second spring 14 is connected to the limit post 13.

[0030] It should be noted that in this embodiment, when the fixed top plate 11 moves, it drives the limiting post 13 on one side to move. The limiting post 13 slides within the fixed sleeve 12 and the moving position of the limiting post 13 is reset by the second spring 14. The limiting post 13, the fixed top plate 11, the sliding top post 6 and the inner top seat 7 are reset, and each ejector pin 8 is reset.

[0031] In one embodiment, such as Figure 2 and Figure 4As shown, multiple limiting slide pillars 9 are slidably arranged inside the inner top seat 7. The limiting slide pillars 9 are fixedly connected to the moving mold 3, and a No. 1 spring 10 is sleeved on the outer side of the limiting slide pillars 9.

[0032] It should be noted that in this embodiment, the inner top seat 7 slides on the outer side of each limiting slide post 9, and the moving position of the inner top seat 7 is reset by the first spring 10 on the outer side of the limiting slide post 9.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, a fixed frame 17 is bolted to the top of the support base 1, and the connecting plate 18 is bolted to the fixed frame 17. Multiple limiting slide rods 21 are symmetrically fixed to one side of the fixed support plate 16, and the limiting slide rods 21 are slidably connected to the connecting side frame 19.

[0034] It should be noted that in this embodiment, the fixed frame 17 is fixedly supported by the connecting plate 18, and the sliding limit rods 21 on one side of the fixed support plate 16 are limited to slide with the connecting side frame 19, thereby improving the adjustment stability of the fixed support plate 16 and the side fixed bracket 15.

[0035] In one embodiment, such as Figures 1 to 3 As shown, a number of guide rods 4 are symmetrically fixed to one side of the fixed mold 2, and a number of guide sleeves 5 that cooperate with the guide rods 4 are symmetrically fixed inside the moving mold 3.

[0036] It should be noted that in this embodiment, multiple guide rods 4 on one side of the fixed mold 2 cooperate with multiple guide sleeves 5 inside the moving mold 3 to improve the mold closing stability of the moving mold 3 and the fixed mold 2.

[0037] In one embodiment, such as Figure 3 and Figure 4 As shown, the bottom of the moving mold 3 is symmetrically fixed with a bottom limit slider 22, which is slidably connected to the support base 1. A limit rod 23 is slidably provided inside the bottom limit slider 22, and the limit rod 23 is fixedly connected to the support base 1.

[0038] It should be noted that, in this embodiment, when the moving mold 3 moves, it causes the bottom limit slider 22 to slide against the support base 1. The bottom limit slider 22 slides on the outside of the limit rod 23, which improves the movement stability of the moving mold 3.

[0039] In one embodiment, such as Figure 1 and Figure 3 As shown, an injection port 24 is provided on one side of the fixed mold 2, and injection channels 25 are symmetrically arranged inside the fixed mold 2. The injection port 24 is connected to the injection channels 25.
