Description
Technical Field
[0001] This utility model belongs to the field of molds, specifically a continuous stamping mold with multiple stripping functions. Background Technology
[0002] Stamping equipment is a type of mechanical equipment used to process metals and other materials. The stamping die is a crucial tool in the stamping process, consisting of multiple components including an upper die holder, lower die holder, upper die plate, lower die plate, guide device, guide pillars, guide sleeves, pressure device, ejector pin, air blowing device, and chip removal device. The structural components of a stamping die will be described in detail below. It applies significant force to material within a special die and uses a punch to apply pressure, causing deformation within the die. This deformation can be used to create parts and products of various shapes. Stamping is a forming process that uses pressure and a die to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. Stamping dies are a pressure processing method in cold stamping, in which a die mounted on a press applies pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired part. Progressive dies refer to stamping dies that complete two or more simple operations in one die. After completing one stamping operation, the material to be stamped moves to the next stamping position to continue stamping. In current stamping die processing, in order to reduce production costs and ensure the quality of stamped workpieces, the external dimensions of the stamped workpiece at each station of the stamping process affect the stamping stroke. The stroke of the material floating device and the unloading device of the die is long, the stamping process cannot be high-speed, the entire stamping process has a long production time and low production efficiency.
[0003] After completing one stamping operation, the material to be stamped moves to the next stamping position to continue stamping. In order to ensure that the material moves smoothly to the next stamping position, it is necessary to separate the material from the upper and lower dies of the current stamping position. However, when the stamping die processes the workpiece, the workpiece is easy to stick to the stamping die. The existing die only uses a stripper plate to strip the material, which has poor stripping effect and affects the continuity of stamping.
[0004] In summary, this utility model provides a continuous stamping die with multiple stripping functions to solve the above problems. Utility Model Content

A lower die core 2 is installed on the lower die base 1, and an upper die core 16 is installed on the upper die base 3. The upper die base 3 and the lower die base 1 are connected by multiple guide telescopic rods 4. Multiple stamping modules 6 are installed on the surface of the lower die core 2 at equal intervals. A stripping plate 5 is movably arranged on the surface of the lower die base 1. Multiple push rods 8 are fixedly connected to the bottom of the stripping plate 5. A guide push plate 7 is fixedly connected to the other end of the push rod 8. The guide push plate 7 is located at the bottom of the lower die base 1. A stripping hole 13 is opened in the middle of the stamping module 6. A stripping rod 10 is arranged in the middle of the stripping hole 13. One end of the stripping rod 10 is horizontally aligned with the stamping module 6, and the other end passes through the stripping hole 13 and is fixedly connected to an adjusting cylinder 11. The adjusting cylinder 11 is movably arranged through the guide push plate 7. A return spring 9 is wound on the surface of the push rod 8. The return spring 9 is fixedly connected to the guide push plate 7 and the bottom of the lower die base 1.
[0020] As one embodiment of this utility model, the surface of the lower mold base 1 is provided with a plurality of push rod holes 17, and the push rod holes 17 are arranged in a one-to-one correspondence with the push rods 8. The push rods 8 move through the push rod holes 17 and are fixedly connected between the stripper plate 5 and the guide push plate 7.
[0021] In one embodiment of this utility model, the surface of the stripper plate 5 is provided with a stamping module hole 14, which is matched with the stamping module 6, and the stamping module 6 passes through the stamping module hole 14.
[0022] In one embodiment of this utility model, the push rods 8 are arranged symmetrically to each other and along the two vertices of the guide push plate 7. The push rods 8 are arranged on both sides of the lower mold core 2.
[0023] As one embodiment of this utility model, the surface of the guide push plate 7 is provided with a plurality of sliding holes 15, and the sliding holes 15 are respectively provided in correspondence with the demolding rods 10. The sliding holes 15 are provided on the surface of the adjusting cylinder 11.
[0024] As one embodiment of this utility model, the surface of the adjusting cylinder 11 is provided with a sliding groove, the sliding hole 15 is sleeved on the surface of the sliding groove, and a tension spring 12 is wound around the surface of the adjusting cylinder 11. The tension spring 12 is located at the bottom of the guide push plate 7.
[0025] In one embodiment of this utility model, the stamping module 6 is equidistantly arranged along the length direction of the lower die core 2, and the stamping module 6 and the lower die core 2 are integrally formed.
[0026] As one embodiment of this utility model, the guide telescopic rods 4 are respectively arranged at both ends of the bottom of the upper mold base 3 and are arranged symmetrically to each other.
[0027] This invention, by setting a stripper plate 5 and a stripper rod 10 in the lower mold base 1, enables the stamping mold to be demolded from two positions. Multiple stripping methods improve stripping efficiency and solve the problem of poor stripping effect of the stripper plate 5 after continuous stamping, ensuring stamping continuity, greatly saving labor, and significantly improving work efficiency.

[0028] Specific working principle: During stamping, the upper die holder 3 presses against the lower die holder 1, and the lower die core 2 matches the upper die core 16 to stamp the workpiece. During stamping, external force presses against the stripper plate 5 on the surface, the stripper plate 5 stretches the recovery spring 9, and then the stripper plate 5 moves down, so the guide push plate 7 moves down with it. When it moves down, it pulls the demolding rod 10 down at the same time. When it moves down to the point where the demolding rod 10 can no longer move, the guide push plate 7 can extend and retract within a small range on the surface of the adjusting cylinder 11 to adjust the compression space. After stamping is completed, the upper die holder 3 detaches from the surface of the lower die holder 1, and then the stripper plate 5 is elastically attracted upward by the restoring spring 9, pushing the material at the upper end, and the stripper rod 10 is driven by the guide push plate 7, while stripping the workpiece from the middle.
