These aspects may be combined with any other aspect or multiple aspects unless explicitly stated otherwise. In particular, any feature considered preferred or advantageous may be combined with one or more other features considered preferred or advantageous.

[0028] In the description of this utility model, it should be understood that the terms "inner", "outer", "upper", "lower", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0029] refer to Figures 1 to 3 As shown, this utility model discloses a reinforcing rib forming mold, comprising: an upper mold assembly 1, which includes an upper mold mounting plate 11, the lower surface of which is connected to at least two upper pressing dies 13; a lower mold assembly 2, located below the upper mold assembly 1 and disposed opposite to it; the lower mold assembly 2 includes a lower mold base 23, the top of which is connected to a lower mold mounting plate 24, the upper surface of which is connected to lower pressing dies 21 corresponding to the upper pressing dies 13, and the lower pressing dies 21 having first positioning pins 22 for positioning the workpiece; and a guide assembly 3, which includes a guide sleeve 32 connected to one of the upper mold assembly 1 and the lower mold assembly 2, and a guide post 31 connected to the other of the upper mold assembly 1 and the lower mold assembly 2.

[0030] Existing loader hood reinforcing ribs mostly employ bending and welding processes. Due to the limitations of the bending process, the resulting parts exhibit significant dimensional accuracy deviations and inconsistent quality, making it difficult to adapt to the pace of high-efficiency production. This, in turn, forces longer production cycles and reduces enterprise productivity. The reinforcing rib forming mold in this embodiment, through the precise cooperation of the upper mold 13 and the lower mold 21, produces parts with high dimensional accuracy and high reliability, thereby improving production efficiency.

[0031] Meanwhile, the upper mold assembly 1 of the reinforcing rib forming mold in this embodiment includes at least two upper molds 13, and the lower mold assembly 2 includes a lower mold 21 that corresponds one-to-one with the upper molds 13. This mold produces two parts in one forming, which improves the matching accuracy between parts and also improves production efficiency.

[0032] In some embodiments, the upper die 13 is a punch, and there are two upper dies 13 arranged symmetrically from left to right. The lower die 21 is a die, and the number of lower dies 21 is the same as the number of upper dies 13 and corresponds one-to-one with the upper dies 13.

[0033] In some embodiments, the lower surface of the upper mold mounting plate 11 is provided with a plurality of first bolt holes, and the periphery of the upper pressing mold 13 is provided with second bolt holes corresponding to the first bolt holes. The upper pressing mold 13 is detachably connected to the upper mold mounting plate 11 by bolts. The top of the lower mold mounting plate 24 is provided with a receiving groove for accommodating the lower pressing mold 21. The periphery of the receiving groove is provided with a plurality of first bolt holes, and the periphery of the lower pressing mold 21 is provided with second bolt holes corresponding to the first bolt holes. The lower pressing mold 21 is installed in the receiving groove at the top of the lower mold mounting plate 24, and the lower pressing mold 21 is detachably connected to the lower mold mounting plate 24 by bolts. When it is necessary to maintain the pressing mold or replace it with a different model of pressing mold, the pressing mold can be disassembled and assembled simply by turning the bolts, which greatly improves the convenience of maintaining or replacing the pressing mold.

[0034] Preferably, in the above embodiments, the second bolt holes on the upper die 13 and the lower die 21 are countersunk holes.

[0035] In some embodiments, the first positioning pin 22 is connected to the recessed cavity of the lower die 21, and there are two first positioning pins 22. The workpiece to be processed is provided with through holes corresponding to the first positioning pins 22. During pressing, the workpiece to be processed is positioned by the first positioning pins 22 to ensure that the workpiece to be processed does not shift during the stamping process, thereby improving the dimensional accuracy and quality reliability of the parts.

[0036] In some embodiments, a second positioning pin 27 is provided at the edge of the pressing die 21. The second positioning pin 27 is used to position the pressing die 21 at its installation position to prevent multiple pressing dies 21 from being misaligned during installation.

[0037] refer to Figure 4As shown, in some embodiments, the upper mold mounting plate 11 is connected to a guide sleeve pad 33, the guide sleeve 32 is mounted on the guide sleeve pad 33, and the guide post 31 is mounted on the lower mold base 23. During the pressing process, the guide post 31 is inserted into the guide sleeve 32 and slides along the axial direction of the guide sleeve 32. This ensures that the upper mold 13 and the lower mold 21 maintain good coaxiality and stability during relative movement, improves the working accuracy and reliability of the mold, avoids problems such as mold offset and vibration during the pressing process, and thus ensures the quality of the pressed parts.

[0038] In some embodiments, a lower mold mounting pad 26 is connected between the lower mold base 23 and the lower mold mounting plate 24.

[0039] In some embodiments, the outer periphery of the upper mold mounting plate 11 and the lower mold base 23 are provided with a plurality of lifting lugs 12 for lifting, so as to facilitate the lifting and transportation of the mold. During the installation, maintenance or replacement of the mold, the lifting lugs 12 can provide reliable connection points for the lifting equipment, ensuring that the mold can be lifted and moved safely and stably, and improving the safety and convenience of mold operation.

[0040] In some embodiments, a safety rod 25 is installed on the lower mold mounting plate 24. The safety rod 25 is disposed between the lower mold mounting plate 24 and the upper mold mounting plate 11 to limit the relative movement distance between the upper die 13 and the lower die 21. This prevents the relative movement of the upper die 13 and the lower die 21 from exceeding a preset range during the pressing process, avoiding damage to the mold due to excessive extrusion or other reasons, and thus protecting the mold and ensuring its safe and stable operation.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
