Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0022] For example, please refer to Figure 1-4 , a thermoforming mold flanging mechanism includes a driving mechanism 10, wherein the driving mechanism 10 includes a driving motor 11, a bidirectional screw 12 connected to the driving end of the driving motor 11, a nut 13 connected to both sides of the bidirectional screw 12 and a push block 14 connected to the top of the nut 13, the top of the push block 14 is connected to a lifting assembly 20, the lifting assembly 20 includes a lifting block 21 slidably connected to the top of the push block 14, a stabilizing column 22 connected to the top of the lifting block 21 and a flanging column 23 connected to the top of the stabilizing column 22, the top of the flanging column 23 is connected to a flanging device 30, the flanging device 30 includes a flanging block 31 connected to the top of the flanging column 23 slidably connected and a reset assembly 32 connected to both sides of the flanging block 31, and a first bevel 311 is provided on one side of the top of the flanging block 31, and the first bevel 311 matches the bevel of the upper mold.

[0023] It should be noted that, in the embodiment, the bidirectional screw rod 12 is driven to rotate by the driving motor 11, thereby driving the nut 13 and the push block 14 on both sides to move in opposite directions, thereby causing the lifting block 21, the stabilizing column 22 and the flanging column 23 to rise and fall, thereby realizing the movement of the flanging block 31 and the reset assembly 32.

[0024] For example, please refer to Figure 1-2 , the top of the push block 14 is provided with a second bevel 141;

[0025] A third oblique edge 211 is provided at the bottom of the lifting block 21 , and the third oblique edge 211 matches the second oblique edge 141 .

[0026] It should be noted that, in the embodiment, the third oblique side 211 cooperates with the second oblique side 141 to facilitate the pushing block 14 to push the lifting block 21 upward.

[0027] For example, please refer to Figure 3 , a fourth oblique edge 231 is provided on one side of the top of the flanging column 23;

[0028] A matching groove is provided on one side of the bottom of the flanging block 31 , and a fifth oblique edge 312 is provided on one side of the matching groove. The fifth oblique edge 312 matches with the fourth oblique edge 231 .

[0029] It should be noted that, in the embodiment, the fifth oblique edge 312 cooperates with the fourth oblique edge 231 to facilitate the flanging column 23 to push the flanging block 31 to move in translation.

[0030] For example, please refer to Figure 2 The reset assembly 32 includes a telescopic member 321 connected to both sides of the flanging block 31, a spring 322 sleeved on the outer wall of the telescopic member 321 and a limiting slider 323 connected to one side of the telescopic member 321, and the limiting slider 323 is slidably connected to the groove body of the lower mold.

[0031] It should be noted that, in the embodiment, the flanging block 31 is reset by the elastic force of the spring 322 .

[0032] For example, please refer to Figure 2 T-shaped sliders 221 are fixed on both sides of the stabilizing column 22, and the T-shaped sliders 221 are slidably connected to the groove body of the lower mold.

[0033] It should be noted that, in the embodiment, the T-shaped slider 221 is used to limit the position of the stabilizing column 22 so that the stabilizing column 22 can only move up and down.

[0034] For example, please refer to Figure 2-3 The fourth oblique side 231 and the second oblique side 141 are rotatably connected to a plurality of rollers 40 on one side.

[0035] It should be noted that, in the embodiment, the roller 40 reduces the friction between the flanging block 31 and the flanging column 23 and between the push block 14 and the lifting block 21, thereby reducing wear between the devices and increasing the service life of the device.

[0036] For example, please refer to Figure 2 and Figure 4 Guide sliders 313 are fixed on both sides of the flanging block 31, and the guide sliders 313 are slidably connected to the L-shaped sliding grooves 50 set in the lower mold.

[0037] It should be noted that, in the embodiment, the guide slider 313 cooperates with the L-shaped slide groove 50 to facilitate limiting the position of the flanging block 31, so that the flanging block 31 first rises and then moves horizontally.

[0038] The specific operation mode of the utility model is as follows:

[0039] In the flanging mechanism of the thermoforming mold, when the upper and lower molds are completely closed, the bidirectional screw 12 is driven by the driving motor 11 to rotate, thereby driving the screw nut 13 and the push block 14 on both sides to move in opposite directions, and the push block 14 squeezes the lifting block 21, thereby causing the lifting block 21, the stabilizing column 22 and the flanging column 23 to rise, and the flanging block 31 is squeezed by the flanging column 23. Moreover, due to the cooperation of the guide slider 313 and the L-shaped slide 50, the flanging block 31 and the reset assembly 32 are raised, and then the flanging block 31 is translated to cooperate with the upper mold, thereby realizing flanging;

[0040] After flanging is completed, the push block 14 is moved by driving the motor 11, the lifting block 21 and the flanging column 23 are lowered by gravity, the flanging block 31 is reset by the elastic force of the spring 322, and then the flanging block 31 and the reset assembly 32 are lowered by gravity.

[0041] The above-described embodiments merely represent implementation methods of the present application. However, those skilled in the art will appreciate that variations and modifications may be made without departing from the spirit of the present application, and these modifications are intended to fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
