[0076] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0077] Example

[0078] Figure 1 This is a perspective view of the shaping jig 100 provided in one embodiment of this application; Figure 2 for Figure 1 Exploded view of the shaping jig 100 in the illustrated embodiment; Figure 3 for Figure 1 A partial structural schematic diagram of the shaping fixture 100 in the illustrated embodiment; Figure 4 for Figure 1 Top view of the slider assembly 20 and the target component 200 in the illustrated embodiment; Figure 5 for Figure 1 Top view of the slider assembly 20 in the illustrated embodiment.

[0079] See Figures 1 to 3 This application provides a shaping fixture 100, including a lower mold base 10, a slider assembly 20, an upper mold base 30, and a push block assembly 40.

[0080] The lower mold base 10 is provided with a sliding groove 10a, which extends along the first direction X. Figure 4 and Figure 5 As shown, the slider assembly 20 includes a first slider 21 and a second slider 22. The first slider 21 includes a first body 211 and a first shaping part 212. The second slider 22 includes a second body 221 and a second shaping part 222. The first body 211 and the second body 221 are slidably disposed in the slide groove 10a along the first direction X, and the first shaping part 212 and the second shaping part 222 correspond to each other along the first direction X. The upper mold base 30 and the lower mold base 10 are disposed opposite each other on the side where the slide groove 10a is provided. The push block assembly 40 is disposed on the side of the upper mold base 30 facing the lower mold base 10. The push block assembly 40 is configured to push the first body 211 and the second body 221 closer to each other along the first direction X when the upper mold base 30 moves toward the lower mold base 10, so that the first shaping part 212 and the second shaping part 222 move away from each other along the first direction X.

[0081] The aforementioned shaping fixture 100 has a first slider 21 and a second slider 22 that can slide along the slide groove 10a. In use, the upper mold base 30 drives the push block assembly 40 to move towards the lower mold base 10, causing the push block assembly 40 to push the first main body 211 and the second main body 221 closer together. This causes the first shaping part 212 and the second shaping part 222 to move away from each other, thereby stretching the inner wall of the target part 200 along the first direction X through the first shaping part 212 and the second shaping part 222, thus shaping the inner wall of the target part 200. Furthermore, since the first main body 211 and the second main body 221 move closer together along the first direction X during shaping, it is beneficial to reduce the size of the slide groove 10a along the first direction X, thereby reducing the volume of the shaping fixture 100.

[0082] A shaping fixture is provided in the related art. When shaping the inner wall of a target part, the fixture stretches the inner wall of the target part by moving two sliders away from each other. Therefore, the shaping fixture needs to provide a large space in the sliding direction of the sliders to accommodate the two sliders and allow them to slide. In the above embodiment, since the first slider 21 and the second slider 22 are close to each other during shaping, it is beneficial to reduce the volume of the shaping fixture 100 in the first direction X.

[0083] In some embodiments, such as Figure 2 As shown, the upper mold base 30 is spaced apart from the lower mold base 10 along the second direction Y, wherein the second direction Y is perpendicular to the first direction X. Figure 5As shown, the first shaping part 212 is provided with a first tensioning part 2121, which protrudes along the second direction Y on the side of the first shaping part 212 facing the upper mold base 30. The second shaping part 222 is provided with a second tensioning part 2221, which protrudes along the second direction Y on the side of the first shaping part 212 facing the upper mold base 30. The first tensioning part 2121 and the second tensioning part 2221 are arranged opposite to each other along the first direction X, so that the first tensioning part 2121 and the second tensioning part 2221 can respectively extend into the target part 200, thereby pulling the target part 200 outward along the first direction X, thereby shaping the inner wall of the target part 200.

[0084] Optionally, such as Figure 4 As shown, the target part 200 can be a frame-shaped part, and the first tension part 2121 and the second tension part 2221 are used to extend into the target part 200.

[0085] Figure 6 for Figure 1 Exploded view of the first slider 21 and the second slider 22 in the illustrated embodiment.

[0086] In some embodiments, such as Figure 5 and Figure 6 As shown, the first body 211 includes a first mating portion 2111 and a first extension portion 2112. The first mating portion 2111 is disposed opposite to and spaced apart from the first shaping portion 212 along the first direction X, thereby defining a first space 21a between the first mating portion 2111 and the first shaping portion 212. The second shaping portion 222 is movably disposed within the first space 21a along the first direction X. The first extension portion 2112 connects the first mating portion 2111 and the first shaping portion 212 along the first direction X. The second body 221 includes a second mating portion 2211 and a second extension portion 2212. The second mating portion 2211 is disposed opposite to and spaced apart from the second shaping portion 222 along the first direction X, thereby defining a second space 22a between the second mating portion 2211 and the second shaping portion 222. The first shaping portion 212 is movably disposed within the second space 22a along the first direction X. The second extension 2212 is connected along the first direction X between the second mating part 2211 and the second shaping part 222. The first mating part 2111 and the second mating part 2211 are respectively connected to the push block assembly 40 (see...). Figure 2 The first mating part 2111 and the second mating part 2211 are aligned so that they can move closer to each other along the first direction X under the push of the push block assembly 40.

[0087] Thus, the first mating part 2111 and the first shaping part 212 are located on both sides of the second shaping part 222 along the first direction X. In use, the second mating part 2211 moves closer to the first mating part 2111 under the push of the push block assembly 40, causing the second shaping part 222 to move closer to the first mating part 2111, thereby moving the second shaping part 222 away from the first shaping part 212. Similarly, the first mating part 2111 moves the first shaping part 212 closer to the second shaping part 222, thereby moving the second shaping part 222 away from the first shaping part 212. Therefore, the target part 200 (see...) is... Figure 4 The inner wall of the first slider 21 is stretched along the first direction X to shape the inner wall of the target part 200. Furthermore, because the first slider 21 and the second slider 22 form a mutually interlocking structure, the structures of the first slider 21 and the second slider 22 in both the first direction X and the third direction Z are more compact, further contributing to reducing the volume of the shaping fixture 100. The third direction Z is perpendicular to both the first direction X and the second direction Y.

[0088] In some embodiments, such as Figure 5 and Figure 6 As shown, the first shaping portion 212 and a portion of the first main body 211 are recessed inward along the second direction Y on the side facing the upper mold base 30 to form a first recess 21b communicating with the first space 21a. The second shaping portion 222 and a portion of the second main body 221 are recessed inward along the second direction Y on the side facing the upper mold base 30 to form a second recess 22b communicating with the second space 22a. The first recess 21b and the second recess 22b communicate to form a receiving groove 20a, which has a connection along the second direction Y with the upper mold base 30 (see...). Figure 2 The opposite groove bottom. A first tensioning portion 2121 and a second tensioning portion 2221 are respectively formed at the groove bottom. Thus, the target part 200 (see...) is accommodated by the receiving groove 20a. Figure 4 When in use, the target part 200 is placed in the receiving groove 20a to limit the target part 200 and facilitate the shaping of the target part 200.

[0089] In some embodiments, such as Figure 6 As shown, the shaping fixture 100 also includes an elastic element 50, which elastically abuts against the first body 211 and the second body 221 to apply an elastic force that moves the first body 211 and the second body 221 away from each other. Thus, after shaping is complete, when the push block assembly 40 (see...) is pushed... Figure 2 After separating from the first slider 21 and the second slider 22, the elastic force of the elastic element 50 can be used to move the first slider 21 and the second slider 22 away from each other and reset them for the next use.

[0090] In some embodiments, such as Figure 6As shown, there are two elastic elements 50, namely a first elastic element 51 and a second elastic element 52. The first main body 211 has a first guide hole extending along the first direction X towards the side facing the second main body 221. A portion of the first elastic element 51 passes through the first guide hole, with one end extending out of the first guide hole and abutting against the second main body 221. The second main body 221 has a second guide hole extending along the first direction X towards the side facing the first main body 211. A portion of the second elastic element 52 passes through the first guide hole, with one end extending out of the second guide hole and abutting against the first main body 211. Thus, by providing two elastic elements 50, the motion stability of the first slider 21 and the second slider 22 when they move away from each other under the action of elastic force is improved.

[0091] Figure 7 for Figure 1 A partial top view of the shaping fixture 100 in the illustrated embodiment.

[0092] In some embodiments, combined with Figure 6 and Figure 7 As shown, the shaping fixture 100 also includes a first limiting block 61 and a second limiting block 62. The first limiting block 61 is disposed within the slide groove 10a and can abut against the side of the first body 211 away from the second body 221 to limit the first body 211. The second limiting block 62 is disposed within the slide groove 10a and can abut against the side of the second body 221 away from the first body 211 to limit the second body 221. Thus, by using the first limiting block 61 and the second limiting block 62, the sides of the first slider 21 and the second slider 22 that are away from each other are respectively limited, thereby restricting the distance between the first slider 21 and the second slider 22.

[0093] Figure 8 for Figure 1 A schematic diagram of the assembly state of the upper mold base 30, the adjusting plate 70, and the push block assembly 40 in the embodiment shown.

[0094] In some embodiments, such as Figure 7 and Figure 8As shown, the first body 211 has a first inclined surface 2113, and the second body 221 has a second inclined surface 2213. The push block assembly 40 includes a first push block 41 and a second push block 42. The first push block 41 has a first driving surface 411 that wedges with the first inclined surface 2113. The first driving surface 411 can abut against the first inclined surface 2113, so that the first push block 41 can push the first body 211 to move along the first direction X toward the side closer to the second body 221. The second push block 42 has a second driving surface 421 that wedges with the second inclined surface 2213. The second driving surface 421 can abut against the second inclined surface 2213, so that the second push block 42 can push the second body 221 to move along the first direction X toward the side closer to the first body 211.

Figure 10 for Figure 1 A schematic diagram of the assembly state of the upper mold base 30 and the push block assembly 40 in the embodiment shown.

[0096] In some embodiments, such as Figure 9 and Figure 10 As shown, the shaping fixture 100 also includes an adjusting plate 70, which is connected to the upper mold base 30 near the lower mold base 10 (see...). Figure 7 On one side, the first pushing block 41 and the second pushing block 42 respectively pass through the adjusting plate 70. The first pushing block 41 has a first stepped surface 412, which is disposed opposite to the side of the adjusting plate 70 away from the upper mold base 30. The first pushing block 41 can move away from the adjusting plate 70 along the second direction Y to define a first gap 100a between the first stepped surface 412 and the adjusting plate 70 along the second direction Y. The second pushing block 42 has a second stepped surface 422, which is disposed opposite to the side of the adjusting plate 70 away from the upper mold base 30. The second pushing block 42 can move away from the adjusting plate 70 along the second direction Y to define a second gap 100b between the second stepped surface 422 and the adjusting plate 70 along the second direction Y. The shaping fixture 100 also includes a first shim and a second shim (not shown in the figure). The first shim is operably inserted into the first gap 100a, and the second shim is operably inserted into the second gap 100b.

[0097] In this way, the distance by which the first push block 41 protrudes from the upper mold base 30 along the second direction Y can be adjusted by the first shim, and the distance by which the second push block 42 protrudes from the upper mold base 30 along the second direction Y can be adjusted by the second shim, thereby adjusting the distance by which the push block assembly 40 can push the first body 211 and the second body 221 closer to each other, that is, adjusting the amount of shaping of the target part 200 along the first direction X.

[0098] In some embodiments, such as Figure 2 As shown, the shaping fixture 100 also includes a pressure plate 80, which is disposed between the adjusting plate 70 and the lower mold base 10, and is movable relative to the adjusting plate 70 along the second direction Y. The pressure plate 80 is used to confine the target part 200 on the lower mold base 10.
