DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] 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 making creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: A sliding cover type injection molding die includes a base 1. The base 1 provides a stable basic support for the entire die, ensuring the stability of the die during the working process. A lower die base 2 is fixedly connected to the top end of the base 1, providing a basic platform for the installation and operation of other components. A slide plate 3 is slidably connected to the top end of the lower die base 2. The sliding design of the slide plate 3 facilitates the opening and closing operations of the die, improving work efficiency. An upper die base 4 is arranged at the top end of the slide plate 3. The upper die base 4 and the lower die base 2 cooperate to complete the injection molding process. A hydraulic cylinder 5 is fixedly connected to the inside of the lower die base 2. The hydraulic cylinder 5 provides a powerful and stable driving force for the related actions of the die. A driving end of the hydraulic cylinder 5 is fixedly connected to a disc 6. The disc 6 can evenly transmit the power of the hydraulic cylinder 5 to other components. An ejector block 7 is rotatably connected to the upper right side of the top end of the disc 6.

[0034] A slide bar 8 is fixedly connected to the top end of the disc 6. The slide bar 8 provides guidance and support for the sliding of a sliding block 9. The sliding block 9 is slidably connected to the outside of the slide bar 8. The sliding block 9 can smoothly slide along the slide bar 8 to achieve corresponding actions. A push plate 10 is fixedly connected to the top end of the sliding block 9. The push plate 10 can push the components in the die to complete specific operations. A linkage component for driving the slide plate 3 to slide is arranged on the front side of the upper die base 4. The linkage component makes the sliding of the slide plate 3 more accurate and coordinated. A buffer component for buffering the die is arranged at the top end of the slide plate 3. The buffer component can reduce the impact force when the die is opened and closed, protecting the die and extending its service life. A feed pipe 17 is slidably connected to the middle of the upper die base 4. The feed pipe 17 facilitates the injection of injection molding materials. A clamping component for clamping the feed pipe 17 is arranged inside the upper die base 4. The clamping component ensures the stability of the feed pipe 17 during the working process.

[0035] Referring to Figure 3 and Figure 4, The linkage assembly includes a linkage rod 13. The linkage rod 13 is rotatably connected to the front end of the right side of the slide plate 3. The linkage rod 13 can effectively transfer the movement of the upper die holder 4 to the slide plate 3 to achieve coordinated movement between the two. The other end of the linkage rod 13 is rotatably connected to the front side of the upper die holder 4, ensuring flexible connection and power transmission between the linkage rod 13 and the upper die holder 4. A slider 12 is fixedly connected to the bottom end of the slide plate 3. The slider 12 can reduce the friction when the slide plate 3 slides, making its sliding smoother. A fixed rod 11 is fixedly connected inside the lower die holder 2. The fixed rod 11 provides a stable track and support for the sliding of the slider 12. The buffer assembly includes four positioning rods 14. The four positioning rods 14 are fixedly connected to the four corners of the top end of the lower die holder 2. The same upper die holder 4 is slidably connected to the outside of the four positioning rods 14, enabling the upper die holder 4 to move smoothly up and down along the positioning rods 14. A moving plate 15 is slidably connected to the outside of each of the four positioning rods 14. The moving plate 15 can slide flexibly on the positioning rods 14 to achieve a buffering effect. Springs 16 are sleeved on the outside of the four positioning rods 14. The springs 16 can absorb the impact force generated when the upper die holder 4 moves, playing a buffering role.

[0036] Refer to Figure 5 , Figure 6 , The clamping assembly includes a limit plate 18. The limit plate 18 is slidably connected inside the upper die holder 4. The limit plate 18 can perform clamping and releasing operations on the feed pipe 17 during the sliding process. A limit block 19 is fixedly connected to the left side of the limit plate 18. The limit block 19 can limit the sliding range of the limit plate 18 to ensure the accuracy of clamping. A telescopic rod 20 is fixedly connected to the right side of the limit plate 18. The telescopic rod 20 provides guidance and support for the movement of the limit plate 18. A spring 21 is sleeved on the outside of the telescopic rod 20. The spring 21 can provide a return force and a buffering force for the limit plate 18 to ensure the stability of clamping.

[0037] Refer to Figure 2 , Figure 3 , The outside of the disk 6 is in contact with the inner wall of the lower die holder 2. This contact ensures the stability of the disk 6 during movement, reducing shaking and deviation. The outside of the slide rod 8 is in contact with the inner wall of the sliding block 9, ensuring that the sliding block 9 can slide precisely and smoothly along the slide rod 8. The slider 12 is slidably connected to the outside of the fixed rod 11. The fixed rod 11 provides a clear sliding path for the slider 12 to ensure the linearity of its movement. The outside of the slider 12 is in contact with the inner wall of the lower die holder 2. Such a contact method helps the smoothness and stability of the sliding of the slider 12.

[0038] Refer to Figures 4 - 6, the moving plate 15 slides inside the upper die holder 4, enabling the moving plate 15 to move flexibly within the upper die holder 4 to achieve a buffering function. The feeding tube 17 is made of cemented carbide, which also has good high-temperature resistance and can maintain the stability of its structure and performance in a high-temperature injection molding environment. One end of the second spring 21 is fixedly connected to one side of the limiting plate 18 so that it can reset after the engaging operation, and the other end of the second spring 21 is fixedly connected to one side of the upper die holder 4.

[0039] Working principle: After the mold is completed, the hydraulic cylinder 5 inside the lower die holder 2 is started. The hydraulic cylinder 5 drives the disc 6 at the top to move up and down. While the disc 6 moves upward, it drives the slide bar 8 to move, and the slide bar 8 further drives the sliding block 9 to move, thereby ejecting the processed mold. When the disc 6 rises, the ejector block 7 at the top of the disc 6 also rises. When it rises to a certain height, the inner top end of the lower die holder 2 squeezes the right end of the ejector block 7, thereby driving the ejector block 7 to rotate. The ejector block 7 further pushes the sliding block 9 again to achieve the effect of secondary ejection. When the upper die holder 4 rises, it drives the linkage rod 13 to rotate. The linkage rod 13 rotates and drives the slide plate 3 to slide on the top of the lower die holder 2. There is a slider 12 at the bottom of the slide plate 3 sliding outside the slider 12 inside the top of the lower die holder 2, which enables the slide plate 3 to move stably on the top of the lower die holder 2.

[0040] When it is necessary to add material to the inside of the lower die holder 2, the upper die holder 4 moves downward. While the upper die holder 4 moves, it drives the moving plate 15 to slide. While the moving plate 15 moves, it squeezes the first spring 16, and the first spring 16 can provide a resilience force, thereby achieving a buffering effect on the slide plate 3 and the lower die holder 2 below, thus extending the service life. When it is not necessary to add material, the material will solidify and block the inner wall of the feeding tube 17, affecting the feeding speed. At this time, pull the feeding tube 17, and the feeding tube 17 can be pulled out, thereby enabling the cleaning of the feeding tube 17. After the cleaning is completed, insert the feeding tube 17 into the upper die holder 4. The telescopic rod 20 at the inner bottom end of the upper die holder 4 squeezes the limiting plate 18, and the spring 21 outside the telescopic rod 20 can provide an elastic force, which can squeeze the limiting plate 18 again, and then squeeze the limiting block 19 on the left side of the limiting plate 18, enabling the limiting block 19 to be tightly engaged with the bottom of the feeding tube 17.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
