[0023] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a base 1, a lower mold 2 is arranged on the base 1, and an upper mold 3 is arranged in the vertical direction of the lower mold 2. The lower mold 2 and the base 1 can be separated. The bellows 6 is first sleeved on the lower mold 2, and the upper mold 3 is sleeved on the top of the bellows 6. When pressing is required, the lower mold 2 starts to move downward under the drive of the driving device (not shown in the figure), and the upper mold 3 approaches the lower mold 2. After the compression of the bellows 6 is completed, the upper mold 3 is reset away from the lower mold 2. At this time, the upper mold 3 is separated from the bellows 6, and the compressed bellows 6 continues to be sleeved on the lower mold 2, and then the compressed bellows 6 is taken out from the lower mold 2.

[0027] The lower mold 2 is provided with a first step 21, and the first step 21 surrounds the lower mold 2. The upper mold 3 is provided with a second step 32, and the second step 32 surrounds the upper mold 3. The first step 21 and the second step 32 are arranged opposite to each other. The upper mold 3 and the lower mold 2 are separated. The first step 21 and the second step 32 are arranged at a distance. The bellows 6 is sleeved on the first step 21 and the second step 32. According to needs, the upper mold 3 moves downward a set distance, and the lower mold 2 is located on the moving path of the upper mold 3. The bellows 6 is squeezed by the first step 21 and the second step 32.

[0028] A third step 23 is also provided on the lower mold 2, and the diameter of the third step 23 is smaller than the diameter of the first step 21. A fourth step 34 is provided on the upper mold 3, and the diameter of the fourth step 34 is smaller than the diameter of the second step 32. The third step 23 and the fourth step 34 are opposite to each other and are arranged at a distance from each other. The distance between the third step 23 and the fourth step 34 is smaller than the distance between the first step 21 and the second step 32.

[0029] The diameter of the first step 21 is equal to the diameter of the second step 32, and the diameter of the third step 23 is equal to the diameter of the fourth step 34, so that the bellows 6 is more easily squeezed by the third step 23 and the fourth step 34, and the third step 23 and the fourth step 34 also form an avoidance interval, the third step 23 surrounds the lower mold 2, and the third step 23 and the first step 21 are arranged at a distance, the fourth step 34 surrounds the upper mold 3, and the fourth step 34 and the second step 32 are arranged at a distance.

[0030] The lower mold 2 is provided with a lower through hole 22 and a sinking platform 24 . The lower through hole 22 is communicated with the sinking platform 24 . The sinking platform 24 is located at the bottom of the lower mold 2 , which is equivalent to the base 1 covering the opening of the sinking platform 24 .

[0031] A guide column 4 is movably arranged in the lower through hole 22. The guide column 4 has a flange 41. The sinking platform 24 is pressed on the flange 41. The upper end of the guide column 4 protrudes from the upper end of the lower mold 2. The bottom of the guide column 4 is placed on the base 1. The flange 41 is restricted by the sinking platform 24, so the guide column 4 cannot move upward.

[0032] An upper through hole 31 is provided on the upper die 3, and the guide pillar 4 extends into the upper through hole 31, so that when the upper die 3 moves downward, the guide pillar 4 plays a guiding role to prevent the upper die 3 from deflecting during the downward movement.

[0033] An upper sinking platform 33 is provided at the bottom of the upper mold 3, and the upper sinking platform 33 is communicated with the upper through hole 31. A guide sleeve 5 is movably provided on the guide column 4, and a convex ring 51 is provided on the guide sleeve 5. The guide sleeve 5 extends into the upper through hole 31, and the convex ring 51 is located in the upper sinking platform 33. The guide sleeve 5 is sleeved on the guide column 4, and the bottom of the guide sleeve 5 is placed on the top of the lower mold 2. Such an arrangement can prevent the upper mold 3 from shaking during the downward movement.

[0034] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
