[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The output shaft of motor 3 is fixedly connected to the connecting shaft of turntable 2. Multiple evenly distributed guide columns 10 are fixedly connected to the top surface of turntable 2. A guide frame 11 is fixedly installed in the center of the front of hot press cover 9. The guide frame 11 can guide the movement of hot press cover 9. One end of spring 16 is fixedly connected to inclined frame 15, and the other end of spring 16 is fixedly connected to forming cover 12. Spring 16 can drive inclined frame 15 to automatically reset through elastic force. Connecting rod 14 is slidably connected to forming cover 12. Support wheel 18 is in contact with inclined frame 15. Support wheel 18 can support inclined frame 15.

[0025] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 Angle adjustment mechanism 6 includes a gear 61. The gear 61 is fixedly connected to the outer side of the connecting shaft of the cooling fan 5. A fixed plate 62 is fixedly connected to the outer side of the support plate 4. A connecting pin 63 is slidably connected inside the fixed plate 62. A snap-fit ​​bracket 64 is fixedly connected to the upper end of the connecting pin 63. A second spring 65 is provided on the outer side of the connecting pin 63. The connecting pin 63 can guide the movement of the snap-fit ​​bracket 64. The snap-fit ​​teeth on the top surface of the snap-fit ​​bracket 64 engage with two adjacent teeth on the gear 61. The snap-fit ​​bracket 64 is slidably connected to the support plate 4. The snap-fit ​​bracket 64 can limit the cooling fan 5 through the gear 61.

[0026] The specific implementation process of this utility model is as follows: In use, the cooling fan 5 is flipped. During the flipping process, the cooling fan 5 drives the gear 61 to rotate. During the rotation of the gear 61, the locking bracket 64 is pushed downward and the second spring 65 is compressed. When the locking bracket 64 is disengaged from the gear 61, the limiting position on the cooling fan 5 can be released. Then the operating angle of the cooling fan 5 can be adjusted. After the adjustment is completed, the second spring 65 is reset. The second spring 65 can drive the locking bracket 64 to engage with the inside of the gear 61 through its elasticity, thus completing the positioning of the angle of the cooling fan 5.

[0027] The raw material is placed inside the molding cover 12, and then the motor 3 is started. The motor 3 drives the turntable 2 to rotate. During the rotation of the turntable 2, the molding cover 12 is rotated downwards towards the hot press cover 9. When the molding cover 12 moves below the hot press cover 9, the hydraulic cylinder 8 drives the hot press cover 9 to cover the outside of the molding cover 12, and the raw material is hot-pressed. After molding, the hydraulic cylinder 8 drives the hot press cover 9 to detach from the molding cover 12. Then the turntable 2 drives the molding cover 12 to rotate. When the molding cover 12 passes under the airflow of the cooling fan 5, the airflow can dissipate heat from the plastic part. During the continuous rotation of the turntable 2, the inclined frame 15 can be driven to contact the support wheel 18. The inclined frame 15 and the support ring 13 on the connecting rod 14 can move. During the movement, the support ring 13 can push out the plastic part, thereby improving the production efficiency of the plastic part.
