Description

Technical Field

[0001] The utility model relates to the technical field of speaker basin frame manufacturing, in particular to a porous speaker basin frame mold. Background Art

[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but it is also the most important component for the sound effect. There are many types of speakers, and the prices vary greatly. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects and resonates with the surrounding air to produce sound.

[0003] At present, a porous speaker basin frame such as Figure 1 As shown, it includes a speaker basket body, and many through holes are formed on the side wall of the speaker basket body. The multiple through holes on the side wall of the existing porous speaker basket are usually punched by a stamping machine. Its working method is: place the speaker basket body on the lower module of the stamping machine, start the stamping machine, move the upper module downward for stamping, so that multiple through holes are formed on the side wall of the speaker basket body, and then adjust the position of the speaker basket body. Repeat the above operation several times, so that a circle of through holes is formed on the side wall of the speaker body.

[0004] In the above scheme, the prior art generates a lot of waste when stamping the speaker basket body. After the stamping is completed, it is inconvenient to discharge the waste out of the mold. The staff needs to clean the waste on the lower module before stamping the speaker basket body again, which leads to low efficiency. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a porous speaker basin frame mold. By providing a discharge assembly, waste materials can be discharged and collected, solving the problem of the prior art that workers need to clear the waste materials before stamping the speaker basin frame body again, thereby improving work efficiency.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A porous speaker basin frame mold comprises an upper mold component and a lower mold component, the upper mold component comprises an upper mold plate, a stamping assembly and an upper mold head, the stamping assembly is arranged at the lower end of the upper mold plate, the upper mold head is arranged on the stamping assembly, and a plurality of upper stamping holes are formed on the side wall of the upper mold head, the lower mold component comprises a lower mold plate and a lower mold head, the lower mold head is fixed at the upper end of the lower mold plate, and a plurality of lower stamping holes aligned with the upper stamping holes are formed on the side wall of the lower mold head, a guide assembly is provided at the upper end of the lower mold plate, and a positioning assembly and a discharge assembly are provided on the lower mold head.

[0008] When it is necessary to stamp the speaker basin frame body, the speaker basin frame body is placed on the lower die head, and the upper template is driven downward by the punching machine, thereby driving the stamping assembly and the upper die head to move downward, and under the action of the stamping assembly, the speaker basin frame body is stamped, so that a plurality of through holes can be stamped on the side wall of the speaker basin frame body, and the waste generated by the stamping is discharged and collected through the discharge assembly, so that the staff does not need to remove the waste, thereby improving work efficiency. After the speaker basin frame body is stamped once, the upper template is controlled by the punching machine to reset, and the position of the speaker basin frame body is adjusted so that the unstamped side is placed on the lower die head, and the speaker basin frame body after the completion of the stamping is positioned by the positioning assembly to prevent the position of the speaker basin frame body after adjustment from deviation. The above operation is repeated several times, so that a circle of through holes can be stamped on the side wall of the speaker basin frame body, and the stamping quality of the speaker basin frame body is not affected.

[0009] By providing a discharge assembly, waste materials can be discharged and collected, solving the problem in the prior art that workers need to clear the waste materials before stamping the speaker basket body again, thereby improving work efficiency.

[0011] Through the above technical scheme, when it is necessary to punch out multiple through holes on the side wall of the speaker basket body, the upper template is driven downward by the punching machine, thereby driving the upper die head downward through the support plate and the two rubber blocks, so that the upper die head is pressed against the side wall of the speaker basket body, and the upper template is continued to be driven downward to deform the two rubber blocks, so that multiple punching rods pass through the multiple upper punching holes to punch the speaker basket body, and the multiple punching rods are inserted into the multiple lower punching holes, so that multiple through holes can be punched out on the side wall of the speaker basket body.

[0012] The utility model is further configured as follows: the guide assembly includes two guide rods symmetrically fixed to the upper end of the lower template, and the lower end of the upper template is formed with a guide channel that cooperates with the guide rods.

[0013] Through the above technical solution, when the upper template is driven to move downward, the guide rod is inserted into the guide channel, so that the upper template can be moved in the specified direction. At the same time, it is ensured that there will be no deflection and vibration when the upper template moves, thereby ensuring that the stamping quality of the speaker basin frame body is not affected.

[0018] The utility model is further configured as follows: the upper end of the guide rod is rounded.

[0019] The above technical solution makes it easy to insert the guide rod into the guide channel.

[0020] The utility model is further configured as follows: the upper end of the positioning rod is configured in a conical shape.

[0021] Through the above technical solution, it is convenient to insert the through hole on the side wall of the speaker basin frame body onto the positioning rod.
