Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment: Please refer to Figures 1 to 6 , a technical solution is provided according to the embodiment of the present invention: An inner door panel shaping die includes an upper die body 1, and further includes a lower die body one 2, a clamping opening one 4 is provided at its first end, and an extension column 6 protrudes from the first end of the lower die body one 2; a lower die body two 3, a clamping opening two 5 is provided at its first end, and the first end of the lower die body two 3 is movably penetrated by the extension column 6; and a locking mechanism 7, which is arranged between the extension column 6 and the lower die body two 3 and can selectively fix the extension column 6 and the lower die body two 3 relatively to limit or allow the extension column 6 to move relative to the lower die body two 3.

[0028] For the inner door panel with the above structure, when the user needs to perform shaping operations on the inner door panel, first, place one end of the inner door panel in the clamping opening one 4 of the lower die body one 2 to ensure that the inner door panel is stably and accurately positioned on the lower die body one 2. Then, align the clamping opening two 5 of the lower die body two 3 with the other end of the inner door panel, and pass the extension column 6 through the lower die body two 3 movably, so that the lower die body one 2 and the lower die body two 3 jointly clamp the inner door panel. After the inner door panel is clamped and fixed, the lower die body one 2 and the lower die body two 3 firmly clamp the inner door panel together through the locking mechanism 7. At this time, the user can use the upper die body 1 to perform shaping operations on the inner door panel to achieve the required shape, facilitating the user to adaptively clamp inner door panels of different sizes.

[0029] In this embodiment, the locking mechanism 7 includes a locking rod 8, and a plurality of locking grooves 9 are spaced apart on the extension column 6 along its length direction. The locking rod 8 movably penetrates the lower mold body 2 3 and extends into the locking groove 9. When the user needs to relatively fix the lower mold body 1 2 and the lower mold body 2 3 or to contact the relatively fixed state, first, the user needs to adjust the position of the lower mold body 2 3 on the extension column 6 according to the size of the inner door panel and the part to be shaped, and then the user inserts the locking rod 8 from one side of the lower mold body 2 3 so that it can movably penetrate the lower mold body 2 3. Pass through lower mold body 2 3 and find the locking groove 9 corresponding to the current position of lower mold body 2 3. At this time, the cooperation between the locking rod 8 and the locking groove 9 will relatively fix lower mold body 1 2 and lower mold body 2 3 to form a stable clamping structure for supporting and fixing the door inner panel; when the user needs to adjust the position of lower mold body 2 3 or release the relative fixed state between lower mold body 1 2 and lower mold body 2 3, the user only needs to pull out the locking rod 8 to withdraw it from the locking groove 9, and then readjust the position of lower mold body 2 3.

[0030] In this embodiment, the locking rod 8 is threadedly connected to the locking groove 9; by threading the locking rod 8 and the locking groove 9, the locking rod 8 is prevented from being separated from the lower mold body 3 after being subjected to external force, thereby improving the stability of the connection between the locking rod 8 and the locking groove 9.

[0031] In this embodiment, a rotating rod 10 is provided at one end of the locking rod 8 away from the lower mold body 2 3; when the user needs to rotate the locking rod 8, the rotating rod 10 will provide the user with a fulcrum for rotating the locking rod 8, so that the user can rotate the locking rod 8 more easily.

[0032] In this embodiment, a limit block 11 is provided at the free end of the extension column 6, and the limit block 11 is elastically abutted by a spring 12; the spring 12 will always elastically abut the limit block 11 to completely insert the extension column 6 into the lower mold body 2 3, thereby increasing the clamping force between the lower mold body 1 2 and the lower mold body 2 3.

[0033] In this embodiment, the limit block 11 is movably penetrated by a guide rod 13; when the extension column 6 moves in the lower mold body 2 3, because the limit block 11 is movably penetrated by the guide rod 13, the extension column 6 will move along the guide rod 13 to increase the stability of the extension column 6 during movement.

[0034] Working principle: When the user needs to perform a shaping operation on the inner door panel, first, place one end of the inner door panel in the clamping opening 4 of the lower die body 2 to ensure that the inner door panel is stably and accurately positioned on the lower die body 2. Then, align the clamping opening 5 of the lower die body 3 with the other end of the inner door panel. The extension column 6 passes through the lower die body 3 movably, so that the lower die body 1 and the lower die body 3 jointly clamp the inner door panel. After the inner door panel is clamped and fixed, the user inserts the locking rod 8 from one side of the lower die body 3, makes it pass through the lower die body 3 movably, and finds the locking groove 9 corresponding to the current position of the lower die body 3. At this time, the cooperation between the locking rod 8 and the locking groove 9 relatively fixes the lower die body 1 and the lower die body 3, forming a stable clamping structure for supporting and fixing the inner door panel. At this time, the user can use the upper die body 1 to perform a shaping operation on the inner door panel to achieve the required shape, which is convenient for the user to adaptively clamp inner door panels of different sizes. When the user needs to adjust the position of the lower die body 3 or release the relative fixed state between the lower die body 1 and the lower die body 3, the user only needs to pull out the locking rod 8 to make it withdraw from the locking groove 9, and then readjust the position of the lower die body 3; by connecting the locking rod 8 and the locking groove 9 in a threaded manner, it is prevented that the locking rod 8 disengages from the lower die body 3 after being subjected to an external force, improving the stability of the connection between the locking rod 8 and the locking groove 9; when the user needs to rotate the locking rod 8, the rotating rod 10 will give the user a fulcrum for rotating the locking rod 8, so that the user can rotate the locking rod 8 more easily; the spring 12 will always elastically abut against the limiting block 11 to completely insert the extension column 6 into the lower die body 3, improving the clamping force between the lower die body 1 and the lower die body 3; when the extension column 6 moves in the lower die body 3, since the limiting block 11 is movably penetrated by the guide rod 13, the extension column 6 will move along the guide rod 13 to increase the stability of the extension column 6 during movement.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
