A horizontal positioning groove communicating with the outside is provided at the lower part of the fixing groove, and a positioning plate is inserted in the positioning groove, and the upper end surface of the positioning plate abuts against the lower end surface of the insert.

[0006] A further improvement of the mold for facilitating the demolding of arc-shaped automobile parts of the utility model is that limiting parts are provided at both ends of the upper part of the fixing groove, and the upper part of the insert blocks the upper part of the fixing groove and is clamped with the limiting parts.

[0007] A further improvement of the mold for facilitating the demolding of arc-shaped automobile parts of the utility model is that a guiding part is provided at one end of the lower end of the insert close to the positioning groove and is arranged obliquely.

[0008] A further improvement of the mold for facilitating the demolding of arc-shaped automotive parts in the present utility model lies in that a second fixing groove is opened downward in the horizontal part at the upper end of the insert. The cross-section of the second fixing groove is T-shaped. A second insert is arranged in the second fixing groove. The upper end surface of the second insert is flush with the upper end surface of the lower template, and the lower end surface is in contact with the bottom of the second fixing groove.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0014] As Figure 1 shown, a mold for facilitating the demolding of arc-shaped automotive parts includes a lower template 1 and an upper template 2. An arc-shaped mold cavity 3 is provided in the middle of the lower template. An arc-shaped stamping part 4 is provided on the upper template. A vertical fixing groove 5 is opened downward at the junction of the arc-shaped mold cavity and the lower template. An insert 6 is arranged in the fixing groove. One end of the insert is flush with the upper end surface of the lower template, and the other end is adapted to fit the mold cavity to form a continuous arc surface. A horizontal positioning groove communicating with the outside is arranged in the lower part of the fixing groove. A positioning plate 7 is inserted in the positioning groove. The upper end surface of the positioning plate abuts against the lower end surface of the insert. During use, the positioning plate is pulled out, so that the insert descends, and thus the relative exposure between the plate and the template is achieved, and thus the demolding of the plate is facilitated.

[0015] Furthermore, limiting parts 8 are provided at both upper ends of the fixing groove. The upper part of the insert blocks the upper part of the fixing groove and is clamped against the limiting parts, ensuring the stability of the insert, preventing it from protruding from the lower template, and also ensuring the stability of the shape of the sheet during stamping.

[0016] One end of the lower end of the insert close to the positioning groove is provided with a guiding part arranged obliquely, which is convenient for the insertion of the positioning plate.

[0017] The downward movement of the insert can also be realized by arranging the telescopic structure vertically.

[0018] Furthermore, a second fixing groove is opened downward in the horizontal part at the upper end of the insert. The cross-section of the second fixing groove is T-shaped. A second insert 9 is arranged in the second fixing groove. The upper end face of the second insert is flush with the upper end face of the lower template, and the lower end face is in contact with the bottom of the second fixing groove. One side of the lower end of the second insert is provided with a second guiding part 10. A horizontal second positioning groove (not shown in the figure) is provided outside the lower end of the second fixing groove. The second positioning groove is arranged in the insert, and a second positioning plate is slidably connected in the second positioning groove.

[0019] The bottom of the second fixing groove can also extend downward and be provided with a telescopic structure for jacking up the second insert, replacing the second positioning groove and the second positioning plate, so as to facilitate the demolding of the sheet.

[0020] The working principle of the present utility model is as follows: The sheet is placed at the die cavity, and the upper template presses down to cooperate with the lower template to realize the stamping and forming of the automotive arc-shaped plate. After the sheet is formed, if there are edge ear plates of the sheet on the upper end face of the lower template, demolding is realized by jacking out with the second insert; if the sheet is completely in the die cavity in an arc shape, the insert is moved downward to expose the sheet, and then the sheet is demolded and blanked.
