[0038] See also Figures 5 to 9 In one embodiment of the present invention, the surface of the workbench 3 is further provided with a cavity 31, and the cavity 31 is provided with a first horizontal guide rail 311, a longitudinal guide rail 312, and a second horizontal guide rail 313. The longitudinal guide rail 312 is distributed between the first horizontal guide rail 311 and the second horizontal guide rail 313. The first horizontal guide rail 311 is located below the second horizontal guide rail 313. The first horizontal guide rail 311 and the second horizontal guide rail 313 are both in sliding contact with the surface of the end head 541. An escape area 3111 is provided at a position corresponding to the first horizontal guide rail 311 and the tooth plate 32 , and the size of the escape area 3111 is larger than the size of the end head 541 .

[0039] In the embodiment of the present invention, the aperture of the stripping plate 46 is smaller than the aperture of the die 43. After the male die 21 and the female die 43 are cooled and formed into the electronic cigarette shell 7, the longitudinal telescopic member 42 controls the upper mold 41 to rise, and the rising guide head 48 drives the electronic cigarette shell 7 into the adsorption sleeve 551 through the stripping plate 46.

[0040] Working principle: After the electronic cigarette shell 7 is cooled and formed, the longitudinal telescopic member 42 is first used to control the upper mold 41 and the dynamic guide rod 47 to rise to a certain height, and the horizontal telescopic member 51 is used to control the lifting frame 55 to enter between the upper mold 41 and the electronic cigarette shell 7. At this time, the end 541 is located in the longitudinal guide rail 312, and the end 541 is in contact with the first horizontal guide rail 311. Then, the longitudinal telescopic member 42 is used to control the upper mold 41 and the dynamic guide rod 47 to rise to a certain height. The rising dynamic guide rod 47 drives the lifting plate 46 to rise together through the guide head 48. Since the aperture of the lifting plate 46 is smaller than the aperture of the concave die 43, the electronic cigarette shell 7 rises with the lifting plate 46 and enters the adsorption sleeve 551 until the electronic cigarette shell 7 is completely separated from the punch 21 and stops. The guide rod rises to the same height along the square hole tube 53. At this time, the end 541 and the second horizontal guide rail 313 are at the same horizontal height. Then, the vacuum pump 56 is used to control the adsorption sleeve 551 to adsorb and fix the electronic cigarette shell 7; Then, the horizontal telescopic member 51 is used to control the lifting rack 55 to move toward the direction close to the material tray placement cavity 33. During this process, the end head 541 slides in contact with the second horizontal guide rail 313. When the lifting rack 55 is completely separated from between the upper mold 41 and the electronic cigarette shell 7, the end head 541 is separated from the second horizontal guide rail 313 and falls onto the surface of the first horizontal guide rail 311 under the action of gravity. The end head 541 enters the avoidance area 3111 of the first horizontal guide rail 311, and the transmission gear 531 that moves with the lifting rack 55 and the bracket 52 is connected to the toothed plate 32 to drive the lifting rack 55 and the hollow square rod 54 to move. The square hole tube 53 is for the purpose of rotating the axis by 90 degrees. During this process, the end head 541 moves and rotates in the avoidance area 3111 without being interfered or limited. When the transmission gear 531 disengages from the tooth plate 32 and continues to move, the end head 541 disengages from the avoidance area 3111. At this time, the rectangular end head 541 is limited in the first horizontal guide rail 311 and can only move horizontally, which is used to prevent the lifting rack 55 from angular deviation. The vacuum pump 56 is used to control the adsorption sleeve 551 to loosen and fix the electronic cigarette shell 7. Several electronic cigarette shells 7 fall into the cavity on the surface of the tray under the action of gravity, thereby realizing the function of automatic directional unloading.

[0041] To sum up, on the one hand, the present application utilizes the cooperation among the lifting plate 46, the movable guide rod 47, the guide head 48, and the lifting rack 55 to automatically separate the formed electronic cigarette shells 7 from the punch 21 and send them into the adsorption sleeve 551. On the other hand, the cooperation among the square hole tube 53, the transmission gear 531, the hollow square rod 54, and the end 541 can automatically adjust the height and angle of the lifting rack 55 to achieve the directional delivery of the formed electronic cigarette shells 7 into the tray. Compared with the existing electronic cigarette shell 7 processing mold, on the one hand, there is no need to purchase a high-cost automated robot for unloading, and on the other hand, the formed electronic cigarette shells 7 can be placed in the specified position in the same direction, which has the characteristics of simple structure, low cost and automatic directional unloading.
