[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A four-in-one electronic cigarette casing mold, such as Figures 1-6 As shown, the system includes a base 1, a lower mold 2 fixedly mounted on the upper surface of the base 1, an upper mold 3 movably mounted above the lower mold 2, a nozzle 4 fixedly mounted on the upper surface of the upper mold 3, a fixing mechanism on the upper surface of the nozzle 4, two positioning blocks 19 fixedly mounted on both outer walls of the lower mold 2, and two positioning blocks 19 fixedly mounted on both outer walls of the upper mold 3, with the positioning blocks 19 engaging with the positioning block 18. A straightening mechanism is provided on the outer wall of the lower mold 2. The fixing mechanism includes an arc-shaped connecting plate 6, which is fixedly mounted on the upper surface of the nozzle 4. A fixing ring 7 is fixedly connected to the upper end of the arc-shaped connecting plate 6. One end of the fixing ring 7 is rotatably connected to a flexible strap 8 via a shaft. The straightening mechanism includes a pull plate 15 and four straightening pressure plates 20. The four straightening pressure plates 20 are rotatably connected to the outer wall of the lower mold 2 via shafts. The pull plate 15 is movably connected to the outer wall of the lower mold 2. A connecting shaft 21 is fixedly connected between two straightening pressure plates 20.

[0029] A fixed outer shell 9 is fixedly connected to the outer wall of the fixed ring 7. Several slots 10 are opened on the outer wall of the fixed ring 7. An insert plate 11 is fixedly connected to the inner wall of the flexible strap 8. The insert plate 11 fits into the slot 10. Movable grooves are opened at both the upper and lower ends of the insert plate 11. A locking block 12 is inserted into each of the two movable grooves. A return spring is installed between one end of the locking block 12 and the inner wall of the movable groove. The upper and lower inner walls of the slot 10 are provided with locking grooves 13, and the locking grooves 13 fit into one end of the locking block 12. Under the action of the return spring, one end of the locking block 12 is driven into the locking groove 13, which can fix the position of the insert plate 11 inside the slot 10.

[0030] In use, the raw material connected to the injection-molded four-in-one electronic cigarette shell is injected through the nozzle 4 into the cavity formed between the base 1 and the lower mold 2. During injection, the pipe connecting the raw material can be connected to the nozzle 4. When connecting, first pass through the position between the fixing ring 7 and the arc-shaped connecting plate 6, then pull the flexible strap 8 along the inside of the fixing shell 9 to make the flexible strap 8 tightly fit the pipe. Then, insert the insert plate 11 into the corresponding slot 10. During insertion, the two locking blocks 12 move with the insert plate 11, and the inclined surfaces of the two locking blocks 12 follow the slot. The inner wall of the mold moves and is gradually squeezed into the movable groove. The return spring is squeezed until the insert plate 11 is fully inserted. Under the action of the return spring, one end of the locking block 12 is driven into the slot 13, which can fix the position of the insert plate 11 inside the slot 10, thereby connecting and fixing the position of the pipe to the nozzle 4. Through the above operation, the flexible strap 8 and the fixing ring 7 can be used to fix different pipes, which is convenient for connecting and fixing different pipes to the nozzle 4 for injection operation, effectively improving the applicability of the mold.

[0031] Two straightening pressure plates 20 are fixedly connected to gear 24 on their outer walls via shafts. Two gears 14 are rotatably connected to the outer walls of the lower mold 2 via shafts. A chain 23 is sleeved between gear 14 and gear 24. A circular plate 26 is fixedly connected to the outer wall of gear 14. A knob 25 is fixedly connected to the outer wall of the circular plate 26. Several fixing grooves are opened on the outer wall of the circular plate 26, and the fixing grooves fit with one end of the pull plate 15. Two vertical rods 16 are fixedly connected to the outer wall of the lower mold 2. Movable plates 17 and support springs are sleeved on the outer walls of the two vertical rods 16. One end of each movable plate 17 is fixedly connected to the pull plate 15. Under the action of the support spring, the two movable plates 17 can be moved down along the vertical rods 16, thereby moving the pull plate 15 down, so that the two ends of the pull plate 15 are respectively inserted into the corresponding fixing grooves on the two circular plates 26, thus fixing the position of gear 14.

[0032] Specifically, when the upper mold 3 and the lower mold 2 are closed, the positioning block 18 engages with the positioning block 2 19, further defining the position between the upper mold 3 and the lower mold 2, making the positional correspondence between the lower mold 2 and the upper mold 3 more accurate. At this time, the pull plate 15 is moved upward through the movable plate 17 and the vertical rod 16, so that both ends of the pull plate 15 are moved out of the two fixed slots, releasing the fixation of the circular plate 26. The two support springs are compressed, and then the two knobs 25 are rotated simultaneously, driving the two gears 14 to rotate simultaneously. With the help of the chain 23, the two gears 24 can be driven to rotate simultaneously, thereby driving each straightening pressure plate 20 to rotate simultaneously, and simultaneously... Pressurize the outer walls of each group of positioning blocks 18 and 19 to further adjust their corresponding positions and ensure accurate positioning. This further corrects the position between the lower mold 2 and the upper mold 3. After pressurization, release the pull plate 15. Under the action of the support spring, the two movable plates 17 can move down along the vertical rod 16, which in turn moves the pull plate 15 down. This allows the two ends of the pull plate 15 to be inserted into the corresponding fixing slots on the two circular plates 26, fixing the position of the gear 14 and thus fixing the position of each straightening pressure plate 20.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
