Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a detachable modular stamping die. Background Technology

[0002] A stamping die mainly consists of an upper die set, a punch, a die cavity, a lower die set, a guiding device, a positioning device, an unloading device, and a fastening device. The core components of the stamping die are the punch and the die cavity. The punch and die cavity have the same shape, and the punch can be inserted into the die cavity. The purpose of cutting and stretching is achieved by controlling the gap between the punch and the die cavity and controlling the insertion depth of the punch. CN221715431U discloses a stamping die, including a die set assembly and a die core assembly. The die set assembly includes an upper die. The die core assembly comprises a lower die core and an upper die core. The lower die core is detachably mounted on the lower die core and is used to hold stamping material. The upper die core is detachably mounted on the upper die core and is equipped with a punch. The punch is adapted to cooperate with the lower die core to punch holes in the stamping material. The beneficial effects are obvious. However, when disassembling the die core assembly, the lower die core is difficult to remove because the die core assembly is embedded in each part of the die core assembly, thereby increasing the labor intensity of the disassembly personnel.

[0003] To address this, we propose a detachable modular stamping die. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable modular stamping die to solve the problem mentioned in the background art that when the die core assembly is removed, the lower die core is difficult to remove because the die core assembly is embedded in each part of the die frame, thereby increasing the labor intensity of the disassembly personnel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable modular stamping die, including a lower die frame, a base plate inside the lower die frame, a lower die core above the base plate, a limiting bead inside the base plate, a spring on one side of the limiting bead, a fastening rod on the other side of the limiting bead, the fastening rod being threadedly connected to the lower die frame, and the fastening rod tightly pressing against the locking block.

[0006] Preferably, the fastening rod has a sliding groove, and the sliding groove is slidably connected to a limiting bead.

[0007] Preferably, the limiting bead is rotatably connected to the inside of the base plate, and the limiting bead is slidably connected to the inner wall of the base plate.

[0008] Preferably, the limiting bead tightly presses against one end of the spring, and the other end of the spring tightly presses against the sealing cap.

[0009] Preferably, the base plate is slidably connected to the lower mold frame, and the base plate tightly presses against the lower mold core.

[0010] Preferably, the locking block tightly presses against the lower mold core, and the locking block is slidably connected to the lower mold frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a lower mold frame to slide and connect to a base plate. The base plate tightly presses against the lower mold core. The base plate is equipped with a limiting bead, which tightly presses against a spring. The spring tightly presses against a fastening rod, and the fastening rod tightly presses against a locking block. The lower mold core can be quickly disassembled by rotating the fastening rod, which effectively reduces the labor intensity of disassembly personnel. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] Please see Figures 1-3 The figure shows a detachable modular stamping die, including a lower die frame 1, a base plate 2 inside the lower die frame 1, a lower die core 3 above the base plate 2, a limiting bead 4 inside the base plate 2, a spring 5 on one side of the limiting bead 4, and a fastening rod 6 on the other side of the limiting bead 4. The fastening rod 6 is threaded to the lower die frame 1 and the fastening rod 6 tightly presses against the locking block 7.

[0020] Furthermore, the fastening rod 6 has a sliding groove, which is slidably connected to the limiting bead 4. The sliding groove and the limiting bead form a sliding connection, ensuring that the limiting bead can maintain stable and smooth movement during the sliding process. This enables the rapid locking and releasing of the lower mold core, improves the flexibility of the disassembly process, and allows operators to more easily complete the disassembly of the mold core.

[0021] Furthermore, the limiting bead 4 is rotatably connected to the inside of the base plate 2, and slidably connected to the inner wall of the base plate 2. By being installed inside the base plate, the limiting bead 4 can rotate at a certain angle inside the base plate, providing greater freedom during disassembly and making it easier to separate from the mold core. The sliding connection ensures the smooth movement of the limiting bead on the inner wall of the base plate. This movement capability allows the limiting bead to adjust its position as needed, thereby more precisely controlling the locking and releasing of the mold core. When disassembling the mold core, the operator can separate the limiting bead from the mold core with a simple operation, greatly simplifying the disassembly process and improving the convenience of disassembly.

[0022] Furthermore, the limiting bead 4 tightly presses one end of the spring 5, and the other end of the spring 5 tightly presses the sealing cover 8. Through the cooperation of the limiting bead, the spring and the sealing cover, the pressing of the limiting bead and the spring ensures that the limiting bead can be stably reset during disassembly, thereby releasing the locking of the mold core. The pressing of the spring and the sealing cover forms an effective sealing barrier, preventing damage or contamination to the inside of the mold caused by the intrusion of external impurities or liquids.

[0023] Furthermore, the base plate 2 is slidably connected to the lower mold frame 1, and the base plate 2 tightly presses against the lower mold core 3. The base plate is slidably connected to the lower mold frame and tightly presses against the lower mold core, which ensures the stable position of the mold core assembly in the mold and also makes it possible to quickly and conveniently disassemble the mold core.

[0024] Furthermore, the locking block 7 tightly presses against the lower mold core 3, and the locking block 7 slides to connect with the lower mold frame 1. By tightly pressing against the lower mold core with the locking block and sliding to connect with the lower mold frame, the stable position of the mold core in the mold is ensured. The lower mold frame can also be slidably connected to achieve rapid mold core positioning. Operators only need to move the locking block to achieve rapid positioning and adjustment of the mold core, which greatly improves work efficiency.

[0025] In this solution, the workflow is as follows: When the lower mold core needs to be disassembled, the operator only needs to rotate the fastening rod 6. During the rotation, the fastening rod will cause the limiting bead 4 to move to one side against the elastic force of the spring 5, thereby releasing the lock on the lower mold core 3. At this time, the lower mold core can be easily removed from the lower mold frame 1 without additional resistance. The whole process is simple and quick, greatly reducing the labor intensity of the disassembly personnel.
