Description

Technical Field

[0001] The utility model relates to the field of die equipment, in particular to a metal forming die for a special-shaped landing gear. Background Art

[0002] The forming dies of current special-shaped landing gears of unmanned aerial vehicles generally adopt fiberglass reinforced plastics. However, for components like special-shaped landing gears, high strength is required. But fiberglass dies have low temperature resistance and small strength, and the dimensional consistency of the landing gears produced by hot pressing is poor. Long-term use will cause the fiberglass dies to deform, resulting in a reduction in the pass rate of the landing gears and an increase in the production cycle. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides a metal forming die for a special-shaped landing gear.

[0004] The technical solution of the utility model is realized as follows: A metal forming die for a special-shaped landing gear includes a mutually cooperating upper die assembly and a lower die assembly. The lower die assembly includes a lower die horizontal part. On both sides of the top of the lower die horizontal part, a first lower die side part and a second lower die side part are connected. On the top of the first lower die side part and the second lower die side part, a first positioning groove is provided. Inside the first positioning groove, a female end of a positioning block is fixedly connected. The upper die assembly includes an upper die horizontal part. On both sides of the top of the upper die horizontal part, a first upper die side part and a second upper die side part are connected. On the bottom of the first upper die side part and the second upper die side part, a second positioning groove is provided. The positions of the first positioning groove and the second positioning groove correspond to each other. At the ends of the first upper die side part and the second upper die side part, a first end die and a second end die are fixedly connected.

[0005] Two overflow grooves are symmetrically arranged on the top of the lower die horizontal part, the first lower die side part and the second lower die side part.

[0006] On the middle position of the top of the lower die horizontal part and on both sides of the overflow grooves, a first auxiliary groove is provided. On both sides of the middle position of the bottom of the upper die horizontal part, a second auxiliary groove is also provided.

[0007] The technical solution of the utility model has the following positive effects: The upper die assembly and the lower die assembly of the utility model are both composed of multiple pieces spliced together, which is convenient for processing; both the upper die assembly and the lower die assembly adopt aluminum alloy materials, with high strength and good consistency of the processed dies; the overflow grooves facilitate the entry of excess material and are convenient for final cleaning; the first auxiliary groove and the second auxiliary groove together form a gap. Inserting a crowbar can quickly separate the upper die assembly and the lower die assembly to quickly remove the product. Brief Description of the Drawings

[0011] As Figures 1-3 shown, a metal forming die for a special-shaped landing gear includes a mutually cooperating upper die assembly 1 and a lower die assembly 2. The lower die assembly 2 includes a lower die horizontal part 3. On both sides of the top of the lower die horizontal part 3, a first lower die side part 4 and a second lower die side part 5 are connected. A first positioning groove 6 is provided on the top of the first lower die side part 4 and the second lower die side part 5. A female positioning block 7 is fixedly connected in the first positioning groove 6. The upper die assembly includes an upper die horizontal part 8. On both sides of the top of the upper die horizontal part 8, a first upper die side part 9 and a second upper die side part 10 are connected. A second positioning groove 11 is provided at the bottom of the first upper die side part 9 and the second upper die side part 10. A male positioning block 17 is fixedly connected in the second positioning groove 11. The positions of the first positioning groove 6 and the second positioning groove 11 correspond to each other. End dies 12 and 13 are fixedly connected to the ends of the first upper die side part 9 and the second upper die side part 10; specifically, the upper die assembly 1 and the lower die assembly 2 are made of 6061 aluminum alloy. The lower die horizontal part 3, the first lower die side part 4 and the second lower die side part 5 of the lower die assembly 1 are fixed by bolts. The upper die horizontal part 8, the first upper die side part 9, the second upper die side part 10, the end die 12 and the end die 13 of the upper die assembly 2 are fixed by bolts. The carbon fiber material of the processing die is placed between the upper die assembly 1 and the lower die assembly 2, and the upper die assembly 1 and the lower die assembly 2 are fixed by screws, and then hot pressing treatment is carried out.

[0012] Two overflow grooves 14 are symmetrically arranged on the top of the lower die horizontal part 3, the first lower die side part 4 and the second lower die side part 5; the overflow grooves 14 on the top of the lower die horizontal part 3, the first lower die side part 4 and the second lower die side part 5 are connected. When the mold is closed and heated, the excess material will enter the overflow grooves 14, which is convenient for cleaning.

[0013] On the top of the lower die horizontal part 3, at the middle position and on both sides of the edges of the overflow grooves 14, a first auxiliary groove 15 is provided. On both sides of the middle position of the bottom of the upper die horizontal part 8, a second auxiliary groove 16 is also provided; specifically, as Figure 1 shown, after the mold is completed, the first auxiliary groove 15 and the second auxiliary groove 16 are combined to form a gap. Inserting a crowbar can quickly separate the upper die assembly 1 and the lower die assembly 2 to quickly take out the product.
