[0023] 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.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a molding die for plastic processing, comprising: an upper die 1; a fixed bracket 2 welded and fixed to the outside of the upper die 1; a lower die 7 placed below the upper die 1, with a fixed support plate 14 symmetrically fixed to the bottom of the lower die 7, and a bottom fixed support plate 13 installed at the bottom of the fixed support plate 14 by bolts; a support frame 11 fixed inside the fixed bracket 2, with a cylinder 12 installed at the bottom of the support frame 11 by bolts, and the output end of the cylinder 12 fixed to the bottom fixed support plate 13; and a top plate 8 placed below the lower die 7, with a plurality of ejector pins 18 symmetrically fixed to the top of the top plate 8, and the ejector pins 18 slidably connected to the lower die 7.

[0025] It should be noted that in this embodiment, power is supplied via an external controller, and the output of cylinder 12 drives the bottom fixed support plate 13, fixed support plate 14, and lower mold 7 to move upward as a whole. The lower mold 7 slides guided by the outside of the guide post 19, and the lower mold 7 drives the guide slide plate 6 to slide on the first limit slide rod 5. The top plate 8 drives the connecting side plate 9 to slide at the upper limit slide rod 5. The lower mold 7 and the upper mold 1 are closed. At this time, the connecting side plate 9 is pushed to the bottom of the side groove 21 to avoid the situation where the connecting side plate 9, top plate 8, and ejector pin 18 are not reset, which would affect the plastic molding in the upper mold 1 and lower mold 7. Material is injected into the upper mold 1 and lower mold 7 through the injection runner 3. After the plastic part is molded in the upper mold 1 and lower mold 7, the cylinder... The output end of cylinder 12 drives the bottom fixed support plate 13, fixed support plate 14 and lower mold 7 to move downward. The lower mold 7 drives the damper 16, spring 17, ejector pin 18 and connecting side plate 9 to move downward as a whole. When the connecting side plate 9 reaches the top position of the inner fixed limit bracket 10, the output end of cylinder 12 continues to drive the bottom fixed support plate 13, fixed support plate 14 and lower mold 7 to move downward. The connecting side plate 9, top plate 8 and ejector pin 18 remain in their original positions. The lower mold 7 moves downward, and the ejector pin 18 can eject the molded plastic part in the lower mold 7. The damper 16 and spring 17 buffer the movement of the top plate 8 and ejector pin 18. After the top plate 8 and ejector pin 18 are ejected, the damper 16 and spring 17 reset them.

[0026] In one embodiment, such as Figures 1 to 5 As shown, a connecting side plate 9 is symmetrically welded and fixed to the outer side of the top plate 8. An inner fixed limiting bracket 10 that cooperates with the connecting side plate 9 is symmetrically fixed to the top of the support frame 11. Multiple first limiting slide rods 5 are symmetrically slidably arranged inside the connecting side plate 9. A side fixing plate 4 is fixed to the top of the first limiting slide rod 5. The side fixing plate 4 is fixed to the upper mold 1. The bottom end of the first limiting slide rod 5 is fixed to the inner fixed limiting bracket 10.

[0027] It should be noted that in this embodiment, the connecting side plate 9 slides to the outside of the first limiting slide rod 5 to guide the movement of the top plate 8, and the movement of the connecting side plate 9 and the top plate 8 is restricted by the internal fixed limiting bracket 10.

[0028] In one embodiment, such as Figures 1 to 5 As shown, a guide slide plate 6 is slidably provided on the outer side of the first limiting slide bar 5, and the guide slide plate 6 is fixedly connected to the lower mold 7.

[0029] It should be noted that in this embodiment, the guide slide plate 6 slides to a limit outside the first limiting slide rod 5 to guide the movement of the lower mold 7.

[0030] In one embodiment, such as Figures 1 to 5As shown, multiple second-position sliding rods 15 are symmetrically fixed to the bottom of the bottom fixed support plate 13, and the second-position sliding rods 15 are slidably connected to the support frame 11.

[0031] It should be noted that, in this embodiment, when the output end of the cylinder 12 drives the bottom fixed support plate 13, the fixed support plate 14 and the lower mold 7 to adjust their height, the bottom fixed support plate 13 drives the multiple second limit slide rods 15 symmetrically positioned at the bottom to slide against the support frame 11, thereby improving the adjustment stability of the bottom fixed support plate 13, the fixed support plate 14 and the lower mold 7.

[0032] In one embodiment, such as Figures 1 to 5 As shown, multiple dampers 16 are symmetrically installed inside the lower mold 7. One end of the damper 16 is connected to the top plate 8, and a spring 17 is sleeved on the outside of the damper 16. One end of the spring 17 is fixedly connected to the lower mold 7, and the other end of the spring 17 is fixedly connected to the top plate 8.

[0033] It should be noted that in this embodiment, the movement of the top plate 8 and the ejector pin 18 is buffered by the damper 16 and the spring 17.

[0034] In one embodiment, such as Figures 1 to 5 As shown, multiple guide pillars 19 are symmetrically fixed to the bottom of the upper mold 1. The guide pillars 19 are slidably connected to the lower mold 7. An injection flow channel 3 is provided inside the upper mold 1.

[0035] It should be noted that in this embodiment, the lower mold 7 is limited and slids on the outside of the guide post 19, and injects material into the upper mold 1 and the lower mold 7 through the injection channel 3, and performs molding process in the inner cavity of the upper mold 1 and the lower mold 7.

[0036] In one embodiment, such as Figures 1 to 5 As shown, a support plate 20 is fixedly connected to the bottom of the side fixing plate 4, and a reset top plate 22 that cooperates with the connecting side plate 9 is fixedly connected to the bottom of the support plate 20. A side groove 21 that cooperates with the reset top plate 22 is opened on the outer side of the guide slide plate 6.

[0037] It should be noted that in this embodiment, when the top plate 8 and the connecting side plate 9 reach the bottom position of the reset top plate 22, the reset top plate 22 pushes the connecting side plate 9 and the top plate 8 to reset, so as to avoid the failure of the ejector pin 18 to reset.
