Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 2-4 The utility model provides an embodiment: an injection mold for an air fryer shell, comprising a lower mold 2, a mold cylinder 11 is installed in the middle and upper part of the lower mold 2, a cavity 12 is opened in the middle and right part of the lower mold 2, the right end surface of the cavity 12 is fixedly connected to a fixed plate 17, the left end surface of the fixed plate 17 is fixedly connected to the mold cylinder 11, the inner bottom surface of the cavity 12 is fixedly connected to a motor 18, the output end of the motor 18 is fixedly connected to a rotating shaft 19, one side edge of the rotating shaft 19 is fixedly connected to a rotating rod 20, the upper end surface of the rotating rod 20 is rotatably connected to a rotating plate 21, the lower end surface of the rotating plate 21 is fixedly connected to a first round rod 22, the lower part of the first round rod 22 is slidably connected to an arc frame 23, one side edge of the arc frame 23 is fixedly connected to a second round rod 24, and the upper end surface of the fixed plate 17 is slidably connected to the arc frame 23. The motor 18 drives the rotating shaft 19 and the rotating rod 20 to rotate, so that the rotating plate 21 can slide in the arc frame 23, and the arc frame 23 can slide horizontally on the fixed plate 17, and the second round rod 24 can intermittently knock on the mold barrel 11. During the raw material injection molding process, the raw material will vibrate due to the knocking of the second round rod 24, so that the raw material is squeezed more tightly, and the raw material fills the mold barrel 11. The produced shell will not be uneven due to bubbles, thereby improving the product molding rate.

[0027] Reference Figure 1 , Figure 2 The lower part of the lower mold 2 is provided with a first cooling cavity 13 and a second cooling cavity 16. The inner wall of the middle part of the first cooling cavity 13 is provided with a second cooling cavity 16. One end of the second cooling cavity 16 is provided on the lower end surface of the mold barrel 11. The inner wall surfaces of both sides of the left and right ends of the first cooling cavity 13 are fixedly connected with water pipes 9. A circulating water pump 8 and a water tank 7 are installed in the middle of the water pipe 9. The water tank 7 is installed on the right side of the circulating water pump 8. The water tank 7 is installed on the front side of the lower mold 2. Ejection components are provided at the left and right ends of the lower mold 2. After the mold production is completed, the circulating water pump 8 is turned on. The water in the water tank 7 will circulate in the water pipe 9, the first cooling cavity 13 and the second cooling cavity 16 due to the circulating water pump 8. The temperature difference between the mold and the cooling water quickly cools the mold to form. This method not only avoids the waste of water, but also speeds up the cooling rate of the mold.

[0028] Reference Figure 1The ejection assembly includes a cylinder 4, a lifting plate 10, an ejection rod 14 and an ejection block 15. The upper parts of the left and right ends of the lower mold 2 are fixedly connected to the connecting plate 5. The lower end surface of the connecting plate 5 is fixedly connected to the cylinder 4. The output end of the cylinder 4 is fixedly connected to the lifting plate 10. The middle surface of the upper end of the lifting plate 10 is fixedly connected to the ejection rod 14. The upper end surface of the ejection rod 14 is fixedly connected to the ejection block 15. The cylinder 4 can make the lifting plate 10 rise and fall, thereby driving the ejection block 15 and the ejection rod 14 in the mold barrel 11 to rise and fall, so that the molded product is separated from the mold barrel 11. This method is simple and convenient, efficient and low cost.

[0029] The upper side of the lower mold 2 is provided with a matching upper mold 1, and an injection hole 6 is opened in the middle of the inner part of the upper mold 1. The raw material enters the lower mold 2 through the injection hole 6.

[0031] Reference Figure 1 , Figure 2 , the cylinder 4 is arranged at the rear side of the water pipe 9, and the ejector rod 14 is arranged at the rear side of the second cooling chamber 16. This arrangement can prevent the second cooling chamber 16 from affecting the lifting and lowering of the ejector rod 14.

[0032] Reference Figure 2 The mold barrel 11 is provided with an ejector block 15, and the inner wall at the lower end of the mold barrel 11 is provided with an ejector block hole matching the ejector block 15. An anti-overflow sealing pad should be installed on the ejector block 15 to make the ejector block 15 tightly connected to the mold barrel 11 and prevent leakage of raw materials.

[0033] Reference Figure 4 The fixing plate 17 is provided with a motor output hole.

[0034] Working principle: During the raw material injection molding process, the motor 18 is started, and the motor 18 rotates to drive the rotation of the rotating shaft 19 and the rotating rod 20, so that the rotating plate 21 slides in the arc frame 23, and the arc frame 23 slides horizontally on the fixed plate 17, and the second round rod 24 can intermittently knock on the mold barrel 11. Due to the knocking of the second round rod 24, the raw material will vibrate, so that the raw material is extruded more compactly, and the raw material fills the mold barrel 11; after the mold is extruded and formed, the circulating water pump 8 is turned on, and the water in the water tank 7 will circulate in the water pipe 9, the first cooling chamber 13 and the second cooling chamber 16 due to the circulating water pump 8, so that the mold is quickly cooled and formed; after molding, the cylinder 4 can make the lifting plate 10 rise and fall, thereby driving the ejector block 15 and the ejector rod 14 in the mold barrel 11 to rise and fall, so that the molded product is separated from the mold barrel 11.
