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.

[0027] For example, please refer to Figure 1-5 A local softening device for automotive thermoformed parts includes a heating box 10, a plurality of heating devices 60 are connected to the top of the heating box 10, an opening and closing device 20 is connected to the top of the heating box 10, sealing mechanisms 30 are connected to both sides of the heating box 10, and partitions 11 are slidably connected to both sides of the heating box 10. A wedge block 111 is fixed to one side of the bottom of the partition 11, and a first bevel is provided on one side of the wedge block 111;

[0028] The bottom of the heating box 10 is connected to a pushing assembly 40 on both sides. The pushing assembly 40 includes a threaded rod 41 connected to the bottom of the heating box 10, a rotating block 42 connected to one side of the threaded rod 41, and a pushing block 43 rotatably connected to one side of the rotating block 42. One side of the pushing block 43 is provided on the second oblique side, and the second oblique side cooperates with the first oblique side.

[0029] The heating box 10 is provided with first threaded holes on both sides of the bottom thereof, and the hole bodies of the first threaded holes are matched with the threaded rods 41 .

[0030] It should be noted that, in the embodiment, the threaded rod 41 is moved by rotating the threaded rod 41, thereby driving the push block 43 to move, and then driving the partition 11 to move, thereby controlling the distance between the partitions 11. The partition 11 cooperates with the heating box 10 to form a plurality of enclosed spaces. Different enclosed spaces are kept at different temperatures by using a plurality of heating devices 60, so that different degrees of softening are achieved in different areas.

[0031] For example, please refer to Figure 5 , fixed plates 12 are fixed on both sides of the heating box 10, and a second threaded hole is provided on one side of the fixed plate 12. The hole body of the second threaded hole is connected to the opening and closing device 20, and the opening and closing device 20 includes a screw rod 22 connected to the hole body of the second threaded hole, a rotating motor 21 connected to one side of the screw rod 22, a support block 23 rotatably connected to the other side of the screw rod 22 and a sliding block 25 rotatably connected to one side of the support block 23, one side of the sliding block 25 is slidably connected to the sealing plate 24, and the top of the sealing plate 24 is rotatably connected to the heating box 10, and limiting slide grooves are provided on both sides of the sealing plate 24, and the groove body of the limiting slide groove is slidably connected to the sliding block 25.

[0032] It should be noted that, in the embodiment, the screw rod 22 is driven to rotate by the rotating motor 21, so that the screw rod 22, the rotating motor 21 and the support block 23 move, and then the sliding block 25 and the sealing plate 24 rotate, and the sliding block 25 slides on the sealing plate 24.

[0033] For example, please refer to Figure 4 The sealing mechanism 30 includes a pneumatic cylinder 31 connected to the top of the heating box 10 and a sealing block 32 connected to the driving end of the pneumatic cylinder 31, and the sealing block 32 cooperates with the placement groove set in the partition 11.

[0034] It should be noted that, in the embodiment, the placement groove is convenient for placing parts, and the sealing block 32 is driven to move by the pneumatic cylinder 31 so that the sealing block 32 cooperates with the placement groove, thereby eliminating gaps between the partition 11 and the parts.

[0035] For example, please refer to Figure 3 A limiting groove is provided on one side of the slot body of the placement slot, and the slot body of the limiting slot is connected to a rebound mechanism 50. The rebound mechanism 50 includes a rebound plate 52 slidably connected to the slot body of the limiting slot and a spring 51 connected to one side of the rebound plate 52. The rebound plate 52 cooperates with the slot body of the placement slot.

[0036] It should be noted that, in the embodiment, the rebound plate 52 is reset by the elastic force of the spring 51 , thereby ejecting the automobile part, making it easier for the staff to remove the part.

[0037] For example, please refer to Figure 2 , a first T-shaped sliding groove 1111 is provided on one side of the first oblique side;

[0038] A first T-shaped sliding block 431 is fixed to one side of the second oblique side, and the first T-shaped sliding block 431 is slidably connected to the groove body of the first T-shaped sliding groove 1111.

[0039] It should be noted that, in the embodiment, the first T-shaped sliding block 431 cooperates with the first T-shaped sliding groove 1111 to facilitate the push block 43 to drive the wedge block 111 to move, thereby preventing the wedge block 111 from being difficult to move.

[0040] For example, please refer to Figure 3 , second T-shaped sliders 112 are fixed on both sides of the bottom of the partition 11;

[0041] The heating box 10 is provided with a second T-shaped chute 13 on both sides of the bottom thereof. The second T-shaped chute 13 is slidably connected to the second T-shaped sliding block 112 .

[0042] It should be noted that, in the embodiment, the second T-shaped sliding groove 13 cooperates with the second T-shaped sliding block 112 to improve the stability of the partition 11 and prevent the partition 11 from shaking.

[0043] For example, please refer to Figure 2 and Figure 5 , a third T-shaped chute 14 is provided on both sides of the top of the heating box 10;

[0044] A third T-shaped slider 211 is fixed to one side of the rotary motor 21 , and the third T-shaped slider 211 is slidably connected to the groove body of the third T-shaped sliding groove 14 .

[0045] It should be noted that, in the embodiment, the third T-shaped sliding block 211 cooperates with the third T-shaped sliding groove 14 to limit the position of the rotating motor 21 and improve the stability of the rotating motor 21 .

[0046] The specific operation mode of the utility model is as follows:

[0047] The above-mentioned local softening device for automotive thermoformed parts rotates the threaded rod 41 to move the threaded rod 41, thereby driving the push block 43 to move, and then driving the partition 11 to move, thereby controlling the distance between the partitions 11. The part is then placed on the placement groove, and then the sealing block 32 is driven to move by the pneumatic cylinder 31, so that the sealing block 32 contacts the part. The elastic force of the spring 51 causes the rebound plate 52 to squeeze the part, so that there is no gap between the partition 11 and the part.

[0048] By rotating the motor 21, the screw rod 22 is driven to rotate, thereby moving the screw rod 22, the rotating motor 21 and the support block 23, and then rotating the sliding block 25 and the sealing plate 24. At the same time, the sliding block 25 slides on the sealing plate 24, thereby sealing the heating box 10. Then, different enclosed spaces are kept at different temperatures through multiple heating devices 60, so that different degrees of softening are achieved in different areas.

[0049] 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.
