[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
[0027] Existing automotive bright trim production primarily utilizes single-step molds, which typically include blanking, forming, folding, and fine-blanking. While single-step molds are simple to maintain, they are time-consuming and labor-intensive to produce, requiring significant labor and time costs. Furthermore, precise alignment between single-step molds is required; otherwise, subsequent steps will misalign with previous ones, resulting in substandard product dimensional accuracy and low yield rates.
[0028] Therefore, based on the above-mentioned technical problems, the present application provides an accessory trimming and folding composite mold, which combines the two single-process molds of the trimming process mold and the folding process mold into a set of composite molds, thereby realizing the integration of the two processes of trimming and folding into one process, reducing the time of material placement, material collection and position adjustment during the production process, ensuring the overall dimensional accuracy while improving production efficiency.
[0029] The application scenario of automobile bright trim production is taken as an example to introduce the structure and usage of the accessory trimming and folding composite mold in this application. The accessory trimming and folding composite mold provided in this application is not only suitable for automobile bright trim production, but also for other application scenarios of multi-process production products, specifically:
[0030] Please refer to Figure 1 as well as Figure 2 A composite mold for trimming and folding accessories includes an upper mold base 1 and a lower mold base 2 arranged vertically opposite to each other, and a trimming mechanism 3 and a folding mechanism 4 are arranged between the upper mold base 1 and the lower mold base 2; the trimming mechanism 3 includes a trimming knife block 32, and the folding mechanism 4 includes a folding knife block 42, and the trimming knife block 32 and the folding knife block 42 are both connected to the upper mold base 1; the upper mold base 1 can be raised and lowered relative to the lower mold base 2. When the upper mold base 1 moves toward the lower mold base 2, the trimming mechanism 3 and / or the folding mechanism 4 can press the accessory, and the trimming knife block 32 and the folding knife block 42 act on the accessory product respectively. By simultaneously arranging the trimming mechanism 3 and the folding mechanism 4 on the upper die base 1 and the lower die base 2, and the trimming lower die core 31 of the trimming mechanism 3 and the folding lower die core 41 of the folding mechanism 4 forming a supporting surface, and the trimming knife block 32 and the folding knife block 42 forming a pressing surface, the upper die base 1 drives the trimming mechanism 3 and the folding mechanism 4 to operate at the same time, thereby combining the originally separate trimming process mold and the folding process mold into a set of composite molds, and combining the trimming and folding processes into one process, thereby reducing the time for material discharge, material collection and position adjustment in the production process, ensuring the overall dimensional accuracy while improving production efficiency.
[0031] In some embodiments, the trimming mechanism 3 and the folding mechanism 4 are arranged in parallel along the working direction.
[0032] Preferably, in some embodiments, the horizontal axis of the trimming mechanism 3 forms an angle with the horizontal axis of the folding mechanism 4. By arranging the trimming mechanism 3 and the folding mechanism 4 at an angle, the space required for the composite mold can be reduced when processing long strip products, resulting in a smaller volume.
[0033] In some embodiments, after the upper mold base 1 moves toward the lower mold base 2, the trimming mechanism 3 can independently press the product together, or the folding mechanism 4 can independently press the product together. In some embodiments, to further improve the accuracy of the trimming and folding blades 32 and 42 in cutting and folding the accessories, respectively, the trimming mechanism 3 and folding mechanism 4 can simultaneously press the product together.
[0034] Specifically, in some embodiments, the trimming mechanism 3 includes an upper mold block 34 and a trimming lower die core 31. The upper mold block 34 is vertically movably connected to the upper die base 1, and the trimming lower die core 31 is fixedly connected to the lower die base 2. The trimming blade 32 is disposed on a side of the upper mold block 34 away from the folding blade 42. The upper mold block 34 and the trimming lower die core 31 are disposed opposite each other. By connecting the upper mold block 34 and the trimming lower die core 31 to the upper die base 1 and the lower die base 2, respectively, the upper mold block 34 and the trimming lower die core 31 are disposed opposite each other, thereby achieving product pressing.
[0035] In some embodiments, a first pressing portion 341 and a first mating portion 311 are protruding from the surface of the upper mold block 34 opposite the lower trimming die core 31. When the upper mold base 1 moves toward the lower mold base 2, the first pressing portion 341 and the first mating portion 311 can press against each other. The provision of the first pressing portion 341 and the first mating portion 311 prevents material shifting and improves trimming accuracy.
[0036] In some embodiments, the first pressing portion 341 and the first matching portion 311 are respectively disposed on the edges of the upper mold block 34 and the trimming lower die core 31 near the trimming blade 32, and the trimming blade 32 abuts against the side wall of the first pressing portion 341. By disposing the first pressing portion 341 and the first matching portion 311 on the edges of the upper mold block 34 and the trimming lower die core 31, respectively, waste material can automatically fall out of the mold after trimming the product.
[0037] In some embodiments, the trimming mechanism 3 further includes a first spring 35, which is connected between the upper die base 1 and the upper die block 34. The first spring 35 is used to drive the upper die block 34 to move toward the trimming lower die core 31. The upper die base 1 and the upper die block 34 are connected by the first spring 35, so that during the pressing process, the first spring 35 provides elastic force to the upper die block 34, which can first fix the product with the elastic force, and then press down the upper die base 1 to achieve pressing, thereby improving the stability of the product during the pressing process and causing the trimming knife block 32 to move further downward relative to the trimming lower die core 31 to remove the waste material.
[0038] In some embodiments, the hemming mechanism 4 includes an upper mold pressing plate 44 and a hemming lower mold core 41. The upper mold pressing plate 44 is vertically movably connected to the upper mold base 1, and the hemming lower mold core 41 is fixedly connected to the lower mold base 2. The upper mold pressing plate 44 and the hemming lower mold core 41 are arranged relative to each other. By connecting the upper mold pressing plate 44 and the hemming lower mold core 41 to the upper mold base 1 and the lower mold base 2 respectively, the upper mold pressing plate 44 and the hemming lower mold core 41 are arranged relative to each other, thereby achieving product pressing.
[0039] In some embodiments, a second pressing portion 441 and a second mating portion 411 are protruding from the surface of the upper mold pressing plate 44 that faces the lower hemming die core 41. When the upper mold base 1 moves toward the lower mold base 2, the second pressing portion 441 and the second mating portion 411 can press against each other. The provision of the second pressing portion 441 and the second mating portion 411 can prevent material deviation and improve trimming accuracy.
[0040] In some embodiments, the folding mechanism 4 further includes a second spring 46, which is connected between the upper die base 1 and the upper die pressing plate 44, and is used to drive the upper die pressing plate 44 to move toward the trimming and folding lower die core 41.
[0041] In some embodiments, the lower die base 2 is provided with an escape space; the hemming lower die core 41 is disposed within the escape space. By locating the hemming lower die core 41 within the escape space, the height difference between the trimming mechanism 3 and the hemming mechanism 4 can be further adjusted, enabling the processing of products with a large height difference between the trimming and hemming parts, thus making the mold suitable for processing bright trim strips of various sizes.
[0042] In some embodiments, at least two workstations are provided between the upper die base 1 and the lower die base 2; each workstation is equipped with a trimming mechanism 3 and a folding mechanism 4. By providing multiple workstations between the upper die base 1 and the lower die base 2, the mold can process multiple products simultaneously, thereby improving production efficiency.

When the upper mold base 1 moves toward the lower mold base 2, the trimming mechanism 3 and / or the folding mechanism 4 can press the accessories, and the trimming knife block 32 and the folding knife block 42 act on the accessories respectively.
[0045] The trimming mechanism 3 includes a trimming upper die plate 33, an upper die pressing block 34, a first spring 35, and a lower die pad 36.

One side of the lower die pad 36 is connected to the lower die base 2. The trimming lower die core 31 is located on the side of the lower die pad 36 away from the lower die base 2. The upper die pressing block 34 and the trimming lower die core 31 are arranged opposite each other. By setting the lower die pad 36, the height difference between the trimming mechanism 3 and the folding mechanism 4 can be adjusted by replacing the lower die pad 36 of different sizes, so that the trimming mechanism 3 and the folding mechanism 4 can perform trimming and folding operations on the product at the same time.
[0046] The trimming blade 32 is disposed on the side of the upper die block 34 away from the folding blade 42. A first spring 35 is connected between the upper die base 1 and the upper die block 34. The first spring 35 is used to drive the upper die block 34 toward the trimming lower die core 31. At the same time, a first pressing portion 341 and a first matching portion 311 are protruding from the side of the upper die block 34 opposite to the trimming lower die core 31. When the upper die base 1 moves toward the lower die base 2, the first pressing portion 341 and the first matching portion 311 can squeeze each other. The first pressing portion 341 and the first matching portion 311 are respectively disposed on the edges of the upper die block 34 and the trimming lower die core 31 near the trimming blade 32, and the trimming blade 32 abuts against the side wall of the first pressing portion 341.
[0047] The hemming mechanism 4 includes a hemming upper die fixing plate 43, an upper die pressing plate 44, an upper die fixing pad 45, and a second spring 46. One side of the hemming upper die fixing plate 43 is connected to the upper die base 1, and the upper die fixing pad 45 is arranged between the upper die base 1 and the hemming upper die fixing plate 43; the hemming blade 42 and the upper die pressing plate 44 are arranged on the side of the hemming upper die fixing plate 43 away from the upper die base 1; the upper die pressing plate 44 is vertically movably connected to the upper die base 1, and one end of the second spring 46 is connected to the hemming upper die fixing plate 43, and the other end is connected to the upper die pressing plate 44.

When the upper die base 1 moves toward the lower die base 2, the second clamping portion 441 and the second matching portion 411 can squeeze each other.
[0048] By providing the hemming upper die fixing plate 43 and arranging the hemming blade block 42 and the upper die pressing plate 44 on the hemming upper die fixing plate 43, the stability of the hemming blade block 42 and the upper die pressing plate 44 is improved. By providing the upper die fixing pad 45, the height difference between the trimming mechanism 3 and the hemming mechanism 4 can be adjusted by replacing the upper die fixing pad 45 of different sizes, so that the trimming mechanism 3 and the hemming mechanism 4 can simultaneously perform trimming and hemming operations on the product.
