Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, and in particular to a material discharge structure for large progressive dies. Background Technology
[0002] Currently, for products with barbs, the final discharge of the continuous mold for such products is quite troublesome because these products cannot be directly cut and ejected by the strip. The only way is to make a hook structure in the last step to hook the product out. However, such mold structures are quite complex, the mold assembly is difficult, and the convenience of mold maintenance is reduced.
[0003] Therefore, further improvements are necessary. Utility Model Content
[0004] The purpose of this utility model is to provide a large progressive die product discharge structure that is simple in structure, highly stable, highly efficient in production, low in cost, and highly practical, so as to overcome the shortcomings of the prior art.
[0005] A large progressive die product ejection structure designed for this purpose includes an upper die part and a lower die part for placing the workpiece. The upper die part is characterized by a hook assembly at its bottom, comprising a mounting component and a hook. The mounting component is fixed to the bottom of the upper die part, and the hook is rotatably mounted on the mounting component. When the upper die part moves the hook assembly downwards to a corresponding position, the hook rotates upwards under the action of the workpiece and retracts into the mounting component. When the upper die part moves the hook assembly upwards, the hook rotates downwards and extends out of the mounting component. When the hook assembly moves upwards to a corresponding position, the hook acts on the workpiece, causing the workpiece to flip and slide outwards from the lower die part.
[0006] The mounting component is equipped with a clearance groove. When the hook is rotated upward, it retracts into the clearance groove, and when the hook is rotated downward, it extends out of the clearance groove.
[0007] The lower mold section is provided with a clearance opening. When the hook assembly moves downward, it passes through the clearance opening, and when the hook assembly moves downward to the lowest position, the hook assembly is inserted into the clearance opening.
[0008] The air vent is equipped with a limiting part to prevent the hook from rotating downwards and extending out of the air vent groove.
[0009] When the hook assembly moves upward and leaves the clearance opening, the hook rotates downward and extends out of the clearance slot.
[0010] The mounting component extends vertically downwards from the upper mold section.
[0011] One end of the hook is provided with a rotating shaft, and the mounting part is provided with a rotating hole, and the rotating shaft is rotatably connected to the rotating hole.
[0012] When the hook assembly moves upward and leaves the clearance opening, the hook rotates downward and extends out of the clearance groove under its own gravity;
[0013] Alternatively, an elastic element is fitted onto the rotating shaft, and the elastic element is positioned between the hook and the mounting component. When the hook assembly moves upward and leaves the clearance opening, the hook rotates downward and extends out of the clearance groove under the elastic force of the elastic element.
[0014] When the hook assembly moves downward to its lowest position, the hook is located below the workpiece.
[0015] The lower mold has an inclined surface on one side, and the workpiece slides out of the lower mold along the inclined surface when it is flipped.
[0016] The large progressive die product ejection structure of this utility model features a hook assembly at the bottom of the upper die section. The hook assembly includes an mounting component and a hook. During the production process, the product is hooked out by the hook and then slides outward from the lower die section. This improves the stability of the die, effectively ejects the product from the die, and prevents the risk of the product failing to exit the die and being crushed, thus greatly improving production efficiency. The hook assembly is positioned at the top, simplifying its structure, improving the convenience of die assembly and maintenance, and reducing die costs. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] See Figures 1-7 The ejection structure of this large progressive die product includes an upper die part 1 and a lower die part 2 for placing workpiece a. Hook assemblies are respectively provided on both sides of the bottom of the upper die part 1. The hook assembly includes a mounting part 3 and a hook 4. The mounting part 3 is fixed to the bottom of the upper die part 1, and the hook 4 is rotatably mounted on the mounting part 3. When the upper die part 1 drives the hook assembly to move downward to the corresponding position, the hook 4 rotates upward under the action of workpiece a and retracts into the mounting part 3. When the upper die part 1 drives the hook assembly to move upward, the hook 4 rotates downward and extends out of the mounting part 3. When the hook assembly moves upward to the corresponding position, the hook 4 acts on the workpiece a, so that the workpiece a flips and slides outward from the lower die part 2.
[0026] The mounting part 3 is provided with a clearance groove 5. When the hook 4 rotates upward, it retracts into the clearance groove 5 to avoid the workpiece a. When the hook 4 rotates downward, it extends out of the clearance groove 5.
[0027] The lower mold part 2 is provided with clearance openings 6 on both sides. When the hook assembly moves downward, it passes through the clearance opening 6. When the hook assembly moves downward to the lowest position, the hook assembly is mounted on the clearance opening 6. The clearance opening 6 is used to avoid the downward moving hook assembly.
[0028] A limiting part 7 is provided on one side of the clearance opening 6 to restrict the hook 4 from rotating downward and extending out of the clearance groove 5. When the hook assembly is inserted into the clearance opening 6, the hook 4 cannot rotate downward and extend out of the clearance groove 5 due to the limiting part 7, thus preventing the workpiece a from being stamped and damaging the mold by rotating the hook 4 downward and extending out of the clearance groove 5.
[0029] When the hook assembly moves upward and leaves the clearance opening 6, the hook 4 rotates downward and extends out of the clearance groove 5.
[0030] Mounting component 3 extends vertically downwards from the upper mold portion 1.
[0031] One end of the hook 4 is provided with a rotating shaft 8, and the lower end of the mounting part 3 is provided with a rotating hole 9. The rotating shaft 8 is rotatably connected to the rotating hole 9, thereby allowing the hook 4 to be rotatably mounted on the mounting part 3.
[0032] When the hook assembly moves upward and leaves the clearance opening 6, the hook 4 rotates downward and extends out of the clearance groove 5 under its own gravity;
[0033] Alternatively, an elastic element, which is a torsion spring, is sleeved on the rotating shaft 8. The elastic element is located between the hook 4 and the mounting part 3. When the hook assembly moves upward and leaves the clearance opening 6, the hook 4 rotates downward and extends out of the clearance groove 5 under the elastic force of the elastic element. When the hook 4 rotates upward and retracts into the clearance groove 5, the elastic element is compressed.
[0034] When the hook assembly moves downward to its lowest position, hook 4 is located below workpiece a.
[0035] A slope 10 is provided on one side of the lower mold part 2. When the workpiece a is flipped, it slides out of the lower mold part 2 along the slope 10.
[0036] The working process of the ejection structure of this large progressive die product:
[0037] During production, the upper die part 1 moves downward under the action of the punch press, and drives the hook assembly to move downward. When the hook assembly moves downward to the corresponding position, the hook 4 touches the workpiece a. Under the action of the workpiece a, the hook 4 rotates upward and retracts into the clearance groove 5. Then the upper die part 1 continues to drive the hook assembly to move downward until the lowest position. At this time, the hook assembly passes through the clearance opening 6, and the hook 4 is located below the workpiece a, and the stamping action is completed. When the die has finished its work, the upper die part 1 opens upward and drives the hook assembly to move upward. When the hook assembly leaves the clearance opening 6, the hook 4 rotates downward and extends out of the clearance groove 5. The upper die part 1 continues to open upward so that the hook 4 hooks one end of the workpiece a, thereby causing the workpiece a to flip and slide outward from the lower die part 2, thus completing the product output.
