Technical Field
[0001] The utility model relates to the technology in the field of speaker net production and manufacturing, in particular to a modular structure of a speaker net punching die. Background Art
[0002] A speaker is a device that converts audio signals into sound. In simple terms, it is a device that amplifies audio signals and then releases sound so that users can hear the sound. Existing speakers are equipped with speaker nets to protect their internal components. However, since speakers are extremely fragile, there are many factors that can affect the sound quality of speakers. Speakers are used in a variety of scenarios, such as homes, offices, public places, etc. According to different application scenarios, speakers are designed in various strange shapes. Even so, these speakers still cannot do without speaker nets.
[0003] The main structure of the current speaker mesh includes a shell, which is formed by stamping of metal plates, including a main plate and a connecting plate. A plurality of mesh holes are formed on the main plate by stamping, and the connecting plate is bent inward and extends from the side edge of the main plate. At present, the mesh holes on the speaker mesh are mainly punched by a punching die, and the main structure of this punching die includes a lower die and an upper die; the lower die has a concave cavity for positioning the speaker mesh, and the bottom surface of the concave cavity is concavely provided with a plurality of blanking holes, and the plurality of blanking holes penetrate to the bottom surface of the lower die; the upper die can be movably arranged above the lower die, and a main punching needle module and a main cylinder are arranged in the upper die, and the main cylinder drives the main punching needle module to move up and down and extend downward from the bottom surface of the upper die or retract upward into the upper die, and each main punching needle of the main punching needle module is directly opposite to each other up and down with the corresponding blanking holes.
[0004] However, for some speaker meshes, the mesh arrangement at both ends is relatively complex and irregular. The punching die in the prior art mainly realizes the mesh shape arrangement of the product through single needle skipping. This single needle skipping structure is prone to needle breakage and cylinder jumping during production operations, and because the overall structure of the mold is relatively complex, the mold repair time is very long, which affects the punching capacity.

[0008] As a preferred solution, the left and right ends of the cavity respectively penetrate the left and right side surfaces of the lower mold to facilitate feeding and discharging of the speaker mesh.
[0009] As a preferred solution, the lower mold includes a lower mold base and multiple pads. The upper and lower surfaces of the lower mold base are penetrated to form multiple cavities. The multiple pads are spliced together and fixed on the lower mold base. The multiple feed holes are located on the corresponding pads and are connected to the corresponding cavities in an upper and lower direction. The structure is simple and easy to manufacture and maintain.
[0010] As a preferred solution, the main punch needle modules are multiple and spaced apart in the front and back, each of which is composed of multiple main punch needles spaced apart in the left and right lateral directions, and each main punch needle module is provided with a main cylinder to facilitate the punching operation in the front and back directions.

[0026] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a lower mold 10 and an upper mold 20.
[0027] The lower mold 10 has a concave cavity 101 for positioning the speaker mesh, and the bottom surface of the concave cavity 101 is concavely provided with a plurality of feed holes 102, and the plurality of feed holes 102 penetrate the bottom surface of the lower mold 10. In this embodiment, the left and right ends of the concave cavity 101 penetrate the left and right side surfaces of the lower mold 10 respectively, so as to feed and discharge the speaker mesh. Specifically, the lower mold 10 includes a lower mold base 11 and a plurality of pads 12, and the upper and lower surfaces of the lower mold base 11 penetrate to form a plurality of cavities 103, and the plurality of pads 12 are spliced together and fixed on the lower mold base 11, and the plurality of feed holes 102 are located on the corresponding pads 12 and are connected to the corresponding cavities 103 in a vertically opposite manner, with a simple structure and easy manufacturing and maintenance.
[0028] The upper mold 20 can be movably arranged up and down just above the lower mold 10, and a main punch needle module 21 and a main cylinder 22 are arranged in the upper mold 20. The main cylinder 22 drives the main punch needle module 21 to move up and down and extend downward from the bottom surface of the upper mold 20 or retract upward into the upper mold 20. Each main punch needle 211 of the main punch needle module 21 is directly opposite to the corresponding blanking hole 102 up and down, and multiple auxiliary punch needle modules 23 and multiple auxiliary cylinders 24 are arranged inside the left and right ends of the upper mold 20. Each auxiliary punch needle module 23 is composed of multiple auxiliary punch needles 231. The multiple auxiliary cylinders 24 respectively drive the multiple auxiliary punch needle modules 23 to move up and down and extend downward from the bottom surface of the upper mold 20 or retract upward into the upper mold 20, and each auxiliary punch needle 231 is directly opposite to the corresponding blanking hole 102 up and down. In this embodiment, the main punch needle module 21 is arranged in a plurality of front-to-back intervals, and each main punch needle module 21 is composed of a plurality of main punch needles 211 arranged in a horizontal interval from left to right. A main cylinder 22 is provided for each main punch needle module 21 to perform punching operations in sequence. Also, the plurality of auxiliary punch needles 231 of the plurality of auxiliary punch needle modules 23 are arranged in different shapes, including a straight line, a triangle, and other irregular shapes, which are not limited and are arranged as needed. Moreover, the auxiliary punch needle modules 23 inside the left and right ends of the upper mold 20 are symmetrical to each other, so that the mesh formed on the speaker mesh is symmetrical to the left and right, which is not limited.
[0029] The working principle of this embodiment is described in detail as follows:
[0030] During operation, the lower die 10 and the upper die 20 are installed on the punching machine. First, the upper die 20 is moved upward to open the mold with the lower die 10. Next, the speaker net to be punched is sent into the concave cavity 101. Then, the upper die 20 is moved downward to close the mold with the lower die 10. After closing the mold, the main punch needle module 21 is driven downward by the main cylinder 22 to punch the mesh of the main body of the speaker net, and multiple auxiliary cylinders 24 respectively drive multiple auxiliary punch needle modules 23 to move downward to punch the mesh at both ends of the speaker net. After the mesh punching is completed, the upper die 20 is moved upward to open the mold with the lower die 10, and finally the speaker net can be pulled out.
