Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a hardware stamping die with an improved structure. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. For hardware processing, molds need to be used for stamping. However, in actual use, hardware stamping molds with similar structures and improved structures still have many defects. For example, when the current mold is used, after the stamping is completed, the stamped parts are located in the lower mold, and the staff needs to take them out. However, the stamped parts fit closely with the lower mold, and it is difficult for the staff to take them out. Therefore, it is necessary to design hardware stamping molds with improved structures. Utility Model Content

The sliding of the connecting block in the inner wall of the connecting groove can make the threaded rod rotate. The rotation of the threaded rod can make the rotating block rotate. At this time, the connecting spring is stretched. After the upper die is separated from the bottom die, the elastic force of the connecting spring can cause the connecting block to reset, and then the connecting plate to reset. At this time, the stamping part can be lifted up. If the connecting spring fails, the staff can rotate the rotating block and rotate the threaded rod to lift the stamping part. Just rotate it slightly to facilitate the staff to take it. After the upper die is separated from the bottom die, the protective block slides in the inner wall of the protective groove, and can also lift the stamping part. Moreover, the protective block can protect the edge position of the stamping part. Therefore, the effect of facilitating the operation of the staff can be achieved.

[0005] Preferably, the rotating mechanism includes a threaded rod connected to the connecting block by a thread, and a rotating block is fixedly connected to one side of the threaded rod. The threads of the two connecting blocks are in opposite directions. The setting of the rotating block can cause the threaded rod to rotate when it is rotated. The rotation of the threaded rod can apply force to the connecting block.

[0007] Preferably, the inner wall cross-section of the protective groove is T-shaped, and the cross-section of the protective block is T-shaped. The T-shaped design can form mutual limitation between the inner wall of the protective groove and the protective block, thereby avoiding separation between the two and facilitating the long-term use of the protective block.

[0008] Preferably, both end outer walls of the bottom mold are fixedly connected with mounting plates, and both end outer walls of the upper mold are fixedly connected with fixing plates.

The moving spring surrounds the moving rod, and the moving rod is arranged to slide in the inner wall of the moving opening. At this time, the fixed plate will drive the upper mold to move, so that the upper mold can perform a stamping operation. The elastic force of the moving spring can automatically reset the upper mold, so that the stamped part can be taken out.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The stamping operation can be carried out by moving the upper die downward. When the stamping part moves downward, force can be applied to the connecting plate. The force on the connecting plate can change the angle between the connecting rod and the horizontal plane of the bottom die. The change in the angle of the connecting rod can make the connecting block slide in the inner wall of the connecting groove. The sliding of the connecting block in the inner wall of the connecting groove can make the threaded rod rotate. The rotation of the threaded rod can make the rotating block rotate. At this time, the connecting spring is stretched. After the upper die is separated from the bottom die, the elastic force of the connecting spring can cause the connecting block to reset, and then the connecting plate is reset. At this time, the stamping part can be lifted up. If the connecting spring fails, the staff can rotate the rotating block and rotate the threaded rod to lift the stamping part. Just rotate it slightly to facilitate the staff to take it. After the upper die is separated from the bottom die, the protective block slides in the inner wall of the protective groove, which can also lift the stamping part. Moreover, the protective block can protect the edge position of the stamping part. Therefore, the effect of facilitating the operation of the staff can be achieved.

[0012] 2. The protective block can slide in the inner wall of the protective groove, and the protective block can move under the downward pressure of the stamping part. After the upper mold rises, the stamping part can be lifted up by the air pressure. The inner wall section of the protective groove with a T-shaped structure can form a mutual limit between the inner wall of the protective groove and the protective block, which can avoid separation between the two and facilitate the long-term use of the protective block. The fixed plate can cooperate with the mounting plate to position the stamping part, and the bottom mold can be fixed with the help of bolts. The moving rod can slide in the inner wall of the moving port. At this time, the fixed plate will drive the upper mold to move, so that the upper mold can be stamped. The elastic force of the moving spring can automatically reset the upper mold, and the stamping part can be taken out. BRIEF DESCRIPTION OF THE DRAWINGS
