[0023] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0024] Seen in Figure 1-10This embodiment provides a handle stamping die, which includes an upper die base 1, an upper clamping plate 2, a first stripper plate 3, a lower die plate 4, and a lower die base 5 arranged sequentially from top to bottom along the height direction. At least one extrusion assembly is provided between the first stripper plate 3 and the lower die plate 4. The extrusion assembly includes a first forming mechanism provided at the upper clamping plate 2, which is used to extrude and form one side of the handle. A second forming mechanism is provided at the lower die plate 4, which is used to extrude and form the side of the handle away from the first forming mechanism. The second forming mechanism includes a punching punch 6, which is used to process the mounting hole at the handle.

[0025] According to the solution provided in this embodiment, the first forming mechanism and the second forming mechanism can extrude and form both sides of the handle, while the punching punch 6 can punch holes in the handle during the extrusion and forming process, thus reducing the processing steps and improving the production efficiency of the handle.

[0026] Understandably, the first and second forming mechanisms are customized based on the finished appearance of the handle.

[0027] Seen in Figure 2 The first forming mechanism includes a first punch 71, and the second forming mechanism includes a second punch 81 and a second stripper plate 82. The first punch 71 and the first stripper plate 82 are used to press the upper end of the handle, and the second punch 81 and the second stripper plate 82 are used to press the lower end of the handle.

[0028] Specifically, the first punch 71 and the second punch 81 respectively press the two sides of the handle, so that the handle can be deformed according to the space defined by the first punch 71, the second punch 81, the first stripper plate 3 and the second stripper plate 82, so as to achieve the purpose of forming the two ends of the handle.

[0029] There are two of each of the first punch 71 and the second punch 81, which are respectively located at both ends of the handle and are used to stamp the complex structure at both ends of the handle. The first punch 71 is designed according to the actual shape requirements of the handle.

[0030] Furthermore, a first mounting hole 21 for suspending the first punch 71 is formed at the upper clamping plate 2, a limiting block 211 is formed at the first mounting hole 21, and a corresponding protrusion 711 is formed at the first punch 71. The protrusion 711 is used to abut against and cooperate with the limiting block 211. A second mounting hole 31 is formed at the first stripper plate 3 to slide and cooperate with the first punch 71.

[0031] With the above structure, the first punch 71 can be mounted on the upper clamping plate 2 to punch the handle. At the same time, the first punch 71 can be disassembled and replaced at any time, so that when the first punch 71 is damaged due to excessive punching, it can be replaced more easily.

[0032] Furthermore, a third mounting hole 51 is formed at the lower die base 5 to conformally mate with the second punch 81, and a fourth mounting hole 41 is formed at the lower die plate 4 to conformally mate with the second punch 81. Both the third mounting hole 51 and the fourth mounting hole 41 are slidably engaged with the second punch 81.

[0033] Seen in Figure 9 The punching punch 6 includes an installation section 61 and a punching section 62 formed sequentially. The diameter of the punching section 62 is smaller than that of the installation section 61. A mating hole 42 is formed at the lower die plate 4. The first mating hole 42 is used for sliding engagement with the installation section 61. A countersunk hole 52 is formed at the lower die base 5. The countersunk hole 52 is used for threaded engagement with the installation section 61. A guide hole 821 is formed at the second stripper plate 82. The guide hole 821 is matched with the punching section 62. Therefore, the installation of the punching punch 6 is better realized, and the replacement of the punching punch 6 is convenient.

[0034] Furthermore, a insertion hole 32 is formed at the first stripper plate 3 corresponding to the punching section 62. The insertion hole 32 is used for the punching punch 6 to be inserted after passing through the handle, which facilitates positioning during punching and thus improves the punching accuracy.

[0035] Seen in Figure 1 Multiple lower pads 9 are provided at intervals at one end of the lower mold base 5 away from the lower mold plate 4.

[0036] Specifically, the pads can act as a buffer, thereby better reducing the impact on the stamping equipment.

[0037] Working principle:

[0038] When using this handle stamping die, the upper die holder 1 is installed on the lifting part of the stamping equipment, the lower die holder 5 is installed on the base of the stamping equipment, the handle blank is placed on the lower die plate 4, and the lifting part extrudes and punches the handle when it descends, thus realizing the stamping manufacturing of the handle.

[0039] Specifically, the first punch 71 and the second punch 81 are used to stamp the shape of the handle, and the punching punch 6 is used to stamp the mounting hole at the handle.

[0040] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
