[0024] 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.

[0025] Referring to Figures 1-3, one embodiment of this utility model provides a sleeve forming mold, comprising: a base plate 1 serving as a supporting body; a support frame 2 fixedly connected to the top of the base plate 1; an upper mold 4 connected to the support frame 2 via a lifting assembly; a lower mold 7 fixedly connected to one end of the support frame 2; a push plate 15 slidably connected to the inner wall of the lower mold 7; a sliding plate 14 fixedly connected to the bottom end of the push plate 15; a support block 8 fixedly connected to the top of the base plate 1; a motor 9 fixedly connected to the front end of the support block 8; the drive end of the motor 9 passing through the support block 8 and fixedly connected to an eccentric wheel 10; and the rear end of the eccentric wheel 10 rotatably connected to... There is a rotating block 11, and a connecting block 12 is rotatably connected to the top of the rotating block 11. A mating block 13 is rotatably connected to the top of the connecting block 12. The top of the mating block 13 is fixedly connected to the bottom of the slide plate 14. A fixing component is provided on the outer wall of the lower mold 7. The lifting component includes an air pump 3 fixedly connected to the top of the support frame 2. The driving end of the air pump 3 passes through the support frame 2 and is fixedly connected to the top of the upper mold 4. Slide rods 5 are fixedly connected to both sides of the top of the upper mold 4. The outer wall of the slide rods 5 is slidably connected to the inner wall of the support frame 2. An injection port 6 is fixedly connected to the top of the upper mold 4. The outer wall of the slide plate 14 is slidably connected to the inner wall of the lower mold 7.

[0026] Specifically, when demolding is required, the air pump 3 is started, and the power generated by the air pump 3 lifts the upper mold 4 upward. At this time, the motor 9 is started, and the drive end of the motor 9 starts to rotate, driving the eccentric wheel 10 connected to it to rotate synchronously. The rotational characteristics of the eccentric wheel 10 cause it to drive the rotating block 11 to move during the rotation. The movement of the rotating block 11 is transmitted to the connecting block 12, which in turn drives the connecting block 12 to move. The connecting block 12 is connected to the mating block 13, which in turn drives the mating block 13 to move. The movement of the mating block 13 will then drive the sliding plate 14 to move. Finally, the movement of the sliding plate 14 causes the push plate 15 connected to it to push the already formed sleeve, realizing the demolding of the sleeve from the mold. Through this efficient demolding method, the mold can complete the demolding process more quickly and enter the next molding operation. This helps to effectively increase the product output per unit time, significantly shorten the overall production cycle of the product, and thus better meet the actual needs of large-scale production.

[0027] Referring to Figures 1, 4, and 5, the fixing assembly includes fixing cylinders 16 fixedly connected to both sides of the outer wall of the lower mold 7. Limiting plates 17 are slidably connected to the inner walls of the fixing cylinders 16. Pull rods 18 are fixedly connected to the inner walls of the limiting plates 17. Springs 19 are provided between the limiting plates 17 and the inner walls of the fixing cylinders 16. Guide rods 20 are fixedly connected to both sides of the bottom end of the upper mold 4. Fixing holes 21 are provided on the inner walls of the guide rods 20 corresponding to the pull rods 18. Guide grooves are provided on the inner walls of the lower mold 7 corresponding to the guide rods 20. One end of each spring 19 is connected to the limiting plate 17, and the other end of each spring 19 is connected to the inner wall of the fixing cylinder 16.

[0028] Specifically, manually pull the lever 18 to completely disengage it from the fixing hole 21. At this time, start the air pump 3. The drive end of the air pump 3 will generate power to drive the upper mold 4 to move. During the movement of the upper mold 4, it will drive the guide rod 20 connected to it to move synchronously. When the guide rod 20 moves, it will accurately insert into the guide groove inside the lower mold 7. This guiding and positioning method can accurately determine the position of the sleeve in the mold, ensuring that during the forming process, each part of the sleeve is formed strictly according to the design requirements, thereby ensuring that the dimensional accuracy of the sleeve meets the standard. After rod 20 is accurately inserted into the guide groove and reaches the preset position, pull rod 18 is released. At this time, spring 19, which is in a compressed state, will release elastic potential energy and push limit plate 17 to move. Since limit plate 17 is connected to pull rod 18, the movement of limit plate 17 will drive pull rod 18 to re-insert into fixing hole 21, completing the fixing of upper mold 4 and lower mold 7, so that the mold forms a stable molding space. Finally, the material for making sleeve is injected into the cavity formed by upper mold 4 and lower mold 7 through slide rod 5. Under the action of the mold, the material is gradually formed into a sleeve that meets the requirements.

[0029] Working principle: First, pull the pull rod 18 to disengage it from the fixed hole 21. Then, start the air pump 3 to drive the upper mold 4 to move. As the upper mold 4 moves, it drives the guide rod 20 to move as well. When the guide rod 20 moves, it inserts into the guide groove inside the lower mold 7 for positioning, thereby accurately determining the position of the sleeve in the mold. This ensures that during the molding process, each part of the sleeve is formed according to the design requirements, guaranteeing the dimensional accuracy of the sleeve. When the sleeve is inserted into place, release the pull rod 18. When the pull rod 18 is released, the spring 19 will spring the limiting plate 17. When the limiting plate 17 is springed, it drives the pull rod 18 to insert into the fixed hole 21 for fixing. Then, the material can be transferred from the slide rod 5. The upper mold 4 and lower mold 7 are injected to form the sleeve. When demolding is required, the air pump 3 is started to lift the upper mold 4. At this time, the motor 9 is started to rotate its drive end, which drives the eccentric wheel 10 to rotate. When the eccentric wheel 10 rotates, it drives the rotating block 11 to move. When the rotating block 11 moves, it drives the connecting block 12 to move. When the connecting block 12 moves, it drives the mating block 13 to move. When the mating block 13 moves, it drives the sliding plate 14 to move. When the sliding plate 14 moves, it drives the push plate 15 to push the formed sleeve to demold. This allows for faster next forming operation, effectively increasing the output per unit time, shortening the overall production cycle of the product, and meeting the needs of large-scale production.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
