[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please see Figure 1-3 The embodiments of this utility model include: A synchronous stamping and forming die for automobile floorboards, comprising an upper die assembly and a lower die assembly.

[0017] The upper mold assembly includes an upper template 1, an upper backing plate 2, an upper clamping plate 3, a stop plate 4, a stripper plate 5, and an upper mold punch 6.

[0018] The upper pad and upper clamping plate are fixedly connected to the bottom surface of the upper template from top to bottom. The stop plate is movably connected to the upper template through an elastic element, and the stripper plate is fixedly connected to the bottom surface of the stop plate. The upper die punch is positioned by the upper clamping plate and fixedly connected to the bottom surface of the upper pad. Its lower part is movably connected to the stop plate and the stripper plate. The bottom end of the upper die punch is provided with an upper forming groove 61 and an upper bending forming punch 62 along the feeding direction.

[0019] A further preferred embodiment is a nitrogen spring as the elastic element.

[0020] In a further preferred embodiment, the stop plate and the stripper plate are provided with through holes that allow the upper die punch to pass through.

[0021] In a further preferred embodiment, the upper forming groove and the upper bending protrusion are an integral structure.

[0022] The lower mold assembly includes a lower mold base 7, a lower pad 8, a lower template 9, a lower mold floating block 10, a nitrogen spring 11, a lower mold limiting insert 12, a lower mold punch 13, and a lower mold pad 14.

[0023] The lower pad and lower template are sequentially arranged on the lower mold base from bottom to top. The lower template has an installation groove. The lower mold floating block is raised and lowered in the installation groove by a nitrogen spring. The nitrogen spring provides force to the lower mold floating block, causing it to move upward and reset under the elastic force of the nitrogen spring. The bottom of the installation groove is provided with a lower mold pad that contacts the bottom surface of the lower mold floating block to limit the minimum downward displacement of the lower mold floating block. A lower mold limiting insert is provided on each side of the installation groove. The limiting protrusions on both sides of the lower mold floating block are movably connected to the limiting grooves on the lower mold limiting inserts to limit the maximum upward displacement of the lower mold floating block through the limiting protrusions and limiting grooves.

[0024] The bottom of the lower die punch is fixedly connected to the mounting groove, and its upper part is movably connected to the lower die floating block. The top of the lower die punch is provided with a lower cutting forming punch 131 and a lower bending forming groove 132 along the feeding direction. The lower cutting forming punch cooperates with the upper forming groove to perform partial (three-sided) punching on the strip 15 and to shape the punched product. The upper bending forming punch cooperates with the lower bending forming groove to bend and shape the uncut part (one side).

[0025] In a further preferred embodiment, the lower die floating block is provided with a through hole that allows the lower die punch to pass through.

[0026] More preferably, two nitrogen springs are symmetrically placed on the lower mold floating block.

[0027] like Figure 3 As shown, when in the semi-closed state, the upper mold assembly descends, causing the strip to be pressed between the stripper plate and the lower mold floating block. At this time, the lower mold floating block is still in the lifted state, the bottom end of the upper mold punch does not contact the strip, and the top end of the lower mold punch contacts the strip, and the strip is about to be punched.

[0028] When the mold is closed, the mold is locked, and the lower mold floating block is pressed down to contact the lower pad. At this time, the lower mold punch protrudes from the upper surface of the lower mold floating block to cooperate with the upper mold punch for punching and forming: the lower punching and forming punch and the upper forming groove cut (break) three sides of the target shape on the strip according to the target shape, and push it upward to form. At the same time, the upper bending and forming punch and the lower bending and forming groove bend and shape the uncut side of the strip upward according to the target shape.

[0029] When the mold is open, the product has been stamped and formed. The upper mold assembly moves upward and separates from the lower mold assembly. At this time, the lower mold floating block is lifted by the nitrogen spring, causing the material strip to separate from the lower mold punch, which plays the role of stripping.

[0030] The beneficial effects of this utility model of a synchronous stamping and shaping die for automobile flooring are: it can simultaneously punch and shape the strip material, which not only improves production efficiency, but also greatly improves the accuracy and stability of punching and shaping, preventing product deformation or inadequate shaping caused by step-by-step punching, thereby improving product yield.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
