Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, and in particular to a tool for producing thin torsion springs that is easy to unclog. Background Technology

[0002] In brush spring production, the material is conveyed through the production cutter and then wound. However, when the wire is thin (0.08mm), it is soft and easy to break, and it is easy to get stuck in the production cutter. The existing production cutter is a one-piece structure. When the material channel on it is blocked, the wire cannot be pulled out and the production cutter is rendered useless, resulting in waste. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a thin torsion spring production tool that is easy to unclog, thus solving the problem of production tools being scrapped when the material channel is blocked.

[0004] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: a thin torsion spring production tool that is easy to unclog, comprising a mold body, wherein the mold body is provided with a material channel, characterized in that: the mold body includes a mold shell and a mold core, the mold core is detachably disposed inside the mold shell and the two are tightly fitted together, the material channel is disposed on the mold core, the mold core includes an upper mold core and a lower mold core, a first through groove is provided on one side of the upper mold core and a second through groove is provided on one side of the lower mold core, and when the upper mold core and the lower mold core are closed, the first through groove and the second through groove are connected to form the material channel.

[0005] Furthermore, the upper mold core and the lower mold core have the same structure, and the first through groove and the second through groove equally divide the material channel.

[0006] The beneficial effects of this utility model are as follows: 1. The mold core of this application is detachably set inside the mold shell to realize the disassembly of the two. The mold core is divided into an upper mold core and a lower mold core to realize the separation of the material channel. This makes it easy to remove the mold core and separate the upper mold core and the lower mold core to remove the blockage when a blockage occurs, so as to clear the material channel and realize the reuse of production tools.

[0007] 2. The mold core and mold shell, and the upper mold core and lower mold core of this application are tightly fitted to ensure stability in use and prevent material from protruding from the connection between the upper mold core and the lower mold core.

[0008] 3. The upper and lower mold cores of this application have the same structure, and the first and second through slots divide the material channel equally. Since the thickness of the material channel is matched with the thickness of the material, the thickness of the material after the material through slots are divided is much greater than the height of the first or second through slot, which prevents the material from protruding from the connection between the upper and lower mold cores. At the same time, the upper and lower mold cores have the same structure after being divided, which facilitates production.

[0018] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0019] like Figures 1-4As shown, a thin torsion spring production tool that facilitates unblocking includes a mold body with a material channel 3. The mold body includes a mold shell 1 and a mold core 2. The mold core 2 is detachably disposed inside the mold shell 1, and the two fit tightly together. The material channel 3 is disposed on the mold core 2. The mold core 2 includes a lower mold core 21 and a lower mold core 22. A second through groove 24 is provided on one side of the lower mold core 21, and a second through groove is provided on one side of the lower mold core 22. When the lower mold core 21 and the lower mold core 22 are closed, the second through groove 24 and the second through groove are connected to form the material channel 3.

[0020] The mold core 2 of this application is detachably installed inside the mold shell 1 to achieve disassembly of the two. The mold core 2 is divided into a lower mold core 21 and a lower mold core 22 to separate the material channel 3. This makes it easy to remove the mold core 2 and separate the lower mold core 21 and the lower mold core 22 to remove the blockage when a blockage occurs, thereby clearing the material channel 3 and enabling the reuse of the production tool. The mold core 2 and the mold shell 1, as well as the lower mold core 21 and the lower mold core 22, are tightly fitted to ensure the stability of use and to prevent material from protruding from the connection between the lower mold core 21 and the lower mold core 22. Example 2

[0021] like Figure 1-4 As shown, this embodiment is obtained by further describing the technical features of the lower mold core 21 and lower mold core 22 based on embodiment one. The remaining technical features are the same as in embodiment one, and the similarities will not be repeated here. The difference between this embodiment and embodiment one is that the lower mold core 21 and lower mold core 22 have the same structure, and the second through groove 24 and the second through groove evenly divide the material channel 3.

[0022] In this embodiment, the lower mold core 21 and the lower mold core 22 have the same structure, and the second through groove 24 and the second through groove evenly divide the material channel 3. Since the thickness of the material channel 3 is matched with the thickness of the material, the thickness of the material after the material through groove is evenly divided is much greater than the height of the second through groove 24 or the second through groove, which prevents the material from protruding from the connection between the lower mold core 21 and the lower mold core 22. At the same time, the lower mold core 21 and the lower mold core 22 have the same structure after being evenly divided, which facilitates production.

[0023] During operation, the lower mold core 21 and the lower mold core 22 are joined together to form the mold core 2. The second through groove 24 or the second through groove is connected to form the material channel 3. The mold core 2 is embedded into the placement hole of the mold shell 1 to complete the assembly of the production tool. It can be used in the same way as the existing production tool (the material enters from one end of the material channel 3 and exits from the other end).

[0024] When material blocks the material channel 3, remove the mold core 2 and separate the lower mold core 21 and lower mold core 22 to clear the blockage. Repeat the above steps in reverse to complete the assembly of the production tool.

[0025] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
