[0025] A cosmetic injection mold includes a housing 1. An operating platform 2 is mounted on the top of the housing 1. A lower mold 3 is mounted on the rear side of the top of the operating platform 2. A through groove 4 is formed in the side wall of the operating platform 2. A threaded rod 5 is positioned in the middle of the through groove 4. Guide rods 6 are positioned inside the through groove 4 and on the left and right sides of the threaded rod 5. Sliding strips 7 are sleeved on the outer walls of the threaded rod 5 and guide rods 6. A motor 8 is mounted on the back of the operating platform 2, corresponding to the threaded rod 5. Vertical plates 9 are symmetrically positioned on the top of the sliding strips 7. A top plate 10 is mounted on the top of the vertical plates 9. A cylinder 11 is mounted on the top of the top plate 10. An upper mold 12 is mounted on the lower drive shaft of the cylinder 11. A suction cup is positioned in the mold groove on the bottom surface of the upper mold 12. 13. The upper mold 12 is equipped with a suction plate 14, and an air extraction pipe 15 is provided on the upper side of the suction plate 14. An air extraction pump 16 is installed on the top of the air extraction pipe 15. A collection box 17 is placed on the top surface of the operating table 2 and in front of the lower mold 3. After the lower mold 3 and the upper mold 12 are separated, the injection-molded cosmetic bottle can be sucked up from the lower mold 3 by the suction cup 13, suction plate 14, air extraction pipe 15 and air extraction pump 16. The threaded rod 5, guide rod 6, slide bar 7 and motor 8 can drive the upper mold 12 to move forward. The collection box 17 can collect the cosmetic bottle. In summary, the design facilitates the discharge and collection of the cosmetic bottle after injection molding.

[0026] In this embodiment, the rear end of the threaded rod 5 passes through the operating table 2 and is connected to the drive shaft of the motor 8. The connection between the threaded rod 5 and the operating table 2 is a rotatable connection. The connection between the slide bar 7 and the threaded rod 5 is a threaded connection. The connection between the slide bar 7 and the guide rod 6 is a sliding connection. The slide bar 7 passes through the through groove 4, and the connection between the slide bar 7 and the through groove 4 is a sliding connection. The suction cup 13 passes through the interior of the upper mold 12 and is connected to the suction plate 14. The suction cup 13 and the suction plate 14 are interconnected. The air extraction pipe 15 passes through the top surface of the upper mold 12, and the air extraction pump 16 is installed on the upper mold 12. On the top surface, the drive shaft of cylinder 11 passes through the top plate 10, and the connection between the drive shaft of cylinder 11 and the top plate 10 is a sliding connection. Through the set suction cup 13, suction plate 14, air extraction pipe 15, and air extraction pump 16, the injection-molded cosmetic bottle can be sucked up from the lower mold 3 after the lower mold 3 and the upper mold 12 are separated.

In summary, the design facilitates the discharge and collection of cosmetic bottles after injection molding.

[0027] The working process of this utility model is as follows: In use, firstly, the cylinder 11 is started to move the upper mold 12 downward, so that the upper mold 12 and the lower mold 3 are closed. Then, the injection material is injected into the lower mold 3. After the cosmetic bottle is injected, cooled and formed, the vacuum pump 16 is started to remove the air from the suction plate 14. Then, the suction cup 13 will pick up the injection-molded cosmetic bottle. Next, the cylinder 11 pulls the upper mold 12 up, and then the cosmetic bottle will be pulled out from the lower mold 3. Then, the motor 8 is started to drive the threaded rod 5 to rotate. At this time, the slide bar 7 will move forward in the through groove 4, thereby driving the upper mold 12 forward. After the upper mold 12 reaches the top of the collection box 17, the movement of the motor 8 is stopped, and then the vacuum pump 16 is turned off. At this time, the air inside the suction plate 14 will be refilled, and then the cosmetic bottle will fall from the suction cup 13 and fall into the collection box 17. At this time, the collection of the cosmetic bottle is completed.
