The placed aluminum parts can be positioned through the positioning plate 12 to prevent the aluminum parts from shifting during stamping. A card slot 13 is provided on the upper surface of the mold base 1, and arc grooves 14 are provided on both sides of the card slot 13. A limiting inclined surface 15 is provided on the side of the arc groove 14 away from the card slot 13. Guide holes 16 are provided at positions near the four corners of the card slot 13. The guide holes 16 are movably connected to the guide rod 52, and the guide rod 52 can be telescopically movable in the guide hole 16.

[0030] In this embodiment, the lower mold 4 includes symmetrically arranged mold blocks, and the ends of the two mold blocks that are separated from each other are movably connected to the arc groove 14 through a rotating shaft. The adjacent ends of the two mold blocks are pressed above the ejection device 2. Under the action of the ejection device 2, the adjacent ends of the two mold blocks are pushed up, but when under pressure, the adjacent ends of the two mold blocks are pressed down at the same time. The aluminum part is pressed into shape under the joint action of the lower mold 4 and the upper mold 51. The two mold blocks are provided with a wear-resistant layer on one side close to the upper mold 51. When the stamped aluminum part is deformed, it will contact the wear-resistant layer of the two mold blocks. The wear-resistant layer reduces the wear of the lower mold 4 by the aluminum part.

[0031] In this embodiment, the ejection device 2 includes a fixed sleeve 21, a first spring 22 and an ejection rod 23. The fixed sleeve 21 is embedded in the mold base 1. The bottom of the fixed sleeve 21 is connected to the first spring 22. The upper end of the first spring 22 is fixedly connected to the lower end of the ejection rod 23.

During stamping, the lifting frame 31 is engaged with the card slot 13. Under stamping, the lower mold 4 is flipped to fit the surface of the lifting frame 31, and the lower mold 4 is merged. The lifting frame 31 can support the lower mold 4. Both ends of the lifting frame 31 are provided with symmetrically distributed first racks 311. The center of the lifting frame 31 is provided with a movable hole matching the ejector rod 23, and the ejector rod 23 extends from the movable hole. Circular holes matching the guide rod 52 are provided near the four corners of the lifting frame 31. The circular holes are used for the movement of the guide rod 52. Second racks 321 are symmetrically provided at both ends of the reset frame 32. The surface of the reset frame 32 is a sloped structure, which is not easy to accumulate impurities and facilitates the impurities to slide off. The first rack 311 and the second rack 321 are respectively The lifting frame 31 is connected to the lifting frame 31 and the lifting cylinder 33 is fixed on the side wall of the mold base 1. The lifting cylinder 33 works to drive the lifting frame 31 to move up. The lifting frame 31 can push the formed aluminum part upward and push the lower mold 4 to flip. One side of the lower mold 4 contacts the limiting slope 15. The limiting slope 15 limits the position of the lower mold 4 and controls the lower mold 4 to flip to a position where impurities can be poured out. It ensures that the lower end of the rotated lower mold 4 extends out of the mold base 1, and the impurities in the lower mold 4 are poured out. The reset frame 32 moves downward under the drive of the second rack 321. When the lifting cylinder 33 is reset, it drives the lifting frame 31 to move downward, and the reset frame 32 moves upward to push the extended part of the lower mold 4 to push the flipped lower mold 4 to reset.

[0033] In this embodiment, the first rack 311 and the second rack 321 are both connected to a sliding bar, and a limiting sliding groove 111 is provided on the support plate 11. The limiting sliding groove 111 is movably connected to the sliding bar. The first rack 311 and the second rack 321 move up or down along the limiting sliding groove 111, and at the same time, the positions of the first rack 311 and the second rack 321 are restricted so that the first rack 311 and the second rack 321 cannot separate from the support plate 11.

[0034] In this embodiment, a screw groove 112 is opened at the upper end of the support plate 11, and an adjusting screw 113 is movably connected inside the screw groove 112. A positioning plate 12 is meshed on the adjusting screw 113. Rotating the adjusting screw 113 can drive the positioning plate 12 to move the position and adjust the distance between the positioning plates 12, so as to be suitable for aluminum parts of different widths.

[0035] In this embodiment, threaded sleeves 121 are fixedly connected to both ends of the positioning plate 12, and the threaded sleeves 121 are meshed with the adjusting screw 113. A telescopic groove 122 is provided on one side of the positioning plate 12. The side of the positioning plate 12 close to the telescopic groove 122 is an inclined structure, which is convenient for the aluminum part to be positioned and slide onto the receiving plate 123. The receiving plate 123 is connected in the telescopic groove 122, and a second spring 124 is equidistantly arranged on one side of the receiving plate 123. The second spring 124 is connected to the telescopic groove 122. Under the support of the second spring 124, one side of the receiving plate 123 extends out of the telescopic groove 122, and a slope is arranged on the side of the receiving plate 123 away from the telescopic groove 122. The position is fixed under the support of the receiving plate 123. When the upper mold 51 moves downward and impacts the aluminum part, the aluminum part pushes the receiving plate 123, the second spring 124 contracts, the receiving plate 123 enters the telescopic groove 122, and the aluminum part can fall into the lower mold 4.

[0036] In this embodiment, the upper mold assembly 5 also includes a stamping cylinder 53 and a mounting plate 54. The output end of the stamping cylinder 53 is fixedly connected to the mounting plate 54. The upper mold 51 is installed on the lower surface of the mounting plate 54. Guide rods 52 are symmetrically arranged at both ends of the mounting plate 54. The guide rods 52 limit the upper and lower movements of the upper mold 51 while limiting the end of the aluminum part. According to the needs of stamping, the upper mold 51 and the lower mold 4 can be replaced to change the stamping shape of the aluminum part.

[0037] Working process: Before use, according to the needs of the aluminum part, select the appropriate upper mold 51 and lower mold 4 for installation, rotate the adjusting screw 113, drive the positioning plate 12 to move the position, adjust the distance between the positioning plates 12 to match the width of the aluminum part, and after adjustment, place the aluminum part between the positioning plates 12, and the receiving plate 123 supports the aluminum part. Turn on the stamping cylinder 53, and the upper mold 51 moves downward under the guidance of the guide rod 52. The upper mold 51 contacts the aluminum part and pushes the aluminum part downward. The aluminum part is pressed against the The receiving plate 123 acts, and the receiving plate 123 shrinks back into the telescopic groove 122, and the aluminum part falls onto the lower mold 4 and applies pressure to the lower mold 4. The lower mold 4 squeezes the ejector rod 23, and the first spring 22 shrinks, and the ejector rod 23 retracts into the fixed sleeve 21. After the lower mold 4 loses the supporting force of the ejector rod 23, the lower mold 4 is laid flat and molded with the upper mold 51 to stamp the aluminum part. After the stamping is completed, the stamping cylinder 53 drives the upper mold 51 to reset, and the pressure of the upper mold 51 on the lower mold 4 disappears. The first spring 2 The lower die 4 is lifted up at one end by the ejector rod 23, and the formed aluminum part in the lower die 4 is separated from the lower die 4. The debris generated during the stamping process is lifted up at one end of the lower die 4 and slides to the other side of the lower die 4 to prevent the debris from being exposed from the middle position of the lower die 4. The lifting cylinder 33 works, and the lifting frame 31 moves up. The lifting frame 31 first pushes the lower die 4 up and down, and the opening at one end of the lower die 4 gradually increases until the aluminum part falls on the lifting frame 31, and the lifting frame 31 moves the formed aluminum part out of the die. The base 1, and finally the lower mold 4 is pushed by the lifting frame 31 to flip downward, and the debris and impurities in the lower mold 4 fall to the set position. At the same time, the lifting frame 31 drives the reset frame 32 to move downward through the transmission of the first rack 311, the pushing gear 34 and the second rack 321. When the lifting cylinder 33 is reset, it drives the reset frame 32 to move upward, and the reset frame 32 acts on one side of the lower mold 4. The upward reset frame 32 applies pressure to the lower mold 4, and the lower mold 4 rotates to the initial position to prevent the aluminum parts from being processed again.

[0038] In summary, the present invention proposes a wear-resistant high-pressure impact mold for aluminum parts, in which the lower mold 4 is designed to be two-piece, and the ejection device 2 lifts one side of the lower mold 4 so that the formed aluminum part can automatically detach from the lower mold 4. The two mold blocks are provided with a wear-resistant layer on one side close to the upper mold 51. When the stamped aluminum part is deformed, it will contact the wear-resistant layers of the two mold blocks. The wear-resistant layer reduces the wear of the lower mold 4 by the aluminum part, and the formed aluminum part is driven to move upward through the lifting component 3, which is convenient for unloading. At the same time, the lifting frame 31 drives the lower mold 4 to flip, and the debris or impurities caused by the stamping in the lower mold 4 can be dumped out of the lower mold 4. A collecting device is set at the dumping position to realize the collection of debris. When the lifting frame 31 is reset, it drives the reset frame 32 to reset the lower mold 4, so that continuous stamping work can be realized. A positioning plate 12 is set at the upper end of the mold base 1 to position the placed aluminum part. During stamping, the aluminum part is prevented from shifting, and the structure is stable.
