Description

Technical Field

[0001] The utility model relates to the technical field of speaker diaphragm processing, in particular to a speaker diaphragm processing and molding device. Background Art

[0002] The speaker diaphragm is a round, wavy membrane under the speaker cone.

[0003] The reason why the speaker makes sound is that the current signal output by the amplifier interacts with the magnet, which in turn drives the voice coil in the magnetic field to do piston-like reciprocating motion. Since the diaphragm and the voice coil are connected together, the diaphragm vibrates back and forth and compresses the air to produce sound.

[0004] The diaphragm in the prior art is usually punched by a stamping tool. After the stamping is completed, the diaphragm and the mold will fit together to form a negative pressure adsorption characteristic, which makes it difficult for the diaphragm to be separated from the mold. The demolding effect can only be achieved by manually lifting the corners of the diaphragm, which greatly reduces the speed of diaphragm production.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0009] Furthermore, the pressure relief mechanism includes a storage cavity located at the bottom of the forming mold, a sealing piston is arranged inside the storage cavity, and a closed cavity is formed between the sealing piston and the storage cavity.

[0010] Furthermore, a positioning rod is provided at the bottom of the sealing piston, a pressure relief pipe penetrating the forming mold is provided at the upper end of the positioning rod, and a one-way valve is provided inside the pressure relief pipe.

[0022] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] According to an embodiment of the utility model, a speaker diaphragm processing and molding device is provided. Embodiment 1:

[0024] like Figure 1-3 As shown, the speaker diaphragm processing and molding equipment according to the embodiment of the utility model includes a positioning bracket 1, a molding mold 2 is arranged at the upper end of the positioning bracket 1, a movable bracket 3 is arranged on one side of the positioning bracket 1, a hot pressing module 4 is arranged at the upper end of the movable bracket 3, and a pressure relief mechanism 5 is arranged at the bottom of the molding mold 2.

[0025] When in use, the diaphragm is placed at the upper end of the molding mold 2, and the raw material is squeezed by the setting of the hot pressing module 4, so that the raw material and the molding mold 2 are fitted together, thereby achieving the effect of pressing and molding. At the same time, the pressure relief mechanism 5 is heated by the heating coil 12 inside the hot pressing module 4, so that the pressure relief mechanism 5 moves and sucks air between the diaphragm workpiece and the molding mold 2. After the device is cooled, the pressure relief mechanism 5 rebounds and pushes the air to separate the diaphragm workpiece from the molding mold 2, thereby achieving the effect of facilitating the demolding of the diaphragm workpiece. Embodiment 2:

[0026] like Figure 1-3 As shown, the pressure relief mechanism 5 includes a storage chamber 6 located at the bottom of the forming mold 2, a sealing piston 7 is arranged inside the storage chamber 6, and a closed cavity 8 is formed between the sealing piston 7 and the storage chamber 6. A positioning rod 9 is arranged at the bottom of the sealing piston 7, and a pressure relief pipe 10 that penetrates the forming mold 2 is arranged at the upper end of the positioning rod 9, and a one-way valve 11 is arranged inside the pressure relief pipe 10. Water is stored inside the closed cavity 8, and the top of the pressure relief pipe 10 of the water in the closed cavity 8 is flush with the bottom surface of the mold groove of the forming mold 2 at room temperature. A heating coil 12 is arranged inside the hot pressing module 4, and the heating coil 12 extends from the center of the hot pressing module 4 to the corners of the hot pressing module 4. Both ends of the mobile bracket 3 are provided with hydraulic telescopic rods 13 connected to the hot pressing module 4.

[0027] When in use, the hot pressing module 4 cooperates with the heating coil 12 to heat and extrude the material at the upper end of the forming mold 2 to achieve the purpose of forming the raw material. During the heating and forming process of the raw material, heat enters the interior of the closed cavity 8 through the forming mold 2 to evaporate the water inside the closed cavity 8, thereby pushing the sealing piston 7, and then the sealing piston 7 pushes the positioning rod 9 to move the pressure relief pipe 10 downward. At this time, air is inhaled through the setting of the one-way valve 11. During the continuous cooling process of the device, the evaporated water condenses into water. At this time, the sealing piston 7 is pulled back, and the inhaled air is compressed through the pressure relief pipe 10 through the setting of the one-way valve 11, so that the air pushes the diaphragm workpiece and the forming mold 2 to separate from each other, thereby achieving the effect of facilitating the rapid separation of the mold and the workpiece.

[0028] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0029] In actual application, the diaphragm is placed at the upper end of the forming mold 2, and the raw material is squeezed by the setting of the hot pressing module 4, so that the raw material and the forming mold 2 are fitted together, thereby achieving the effect of pressing and forming. At the same time, the pressure relief mechanism 5 is heated by the heating coil 12 inside the hot pressing module 4, so that the pressure relief mechanism 5 moves and sucks air between the diaphragm workpiece and the forming mold 2. After the device is cooled, the pressure relief mechanism 5 rebounds and pushes the air to separate the diaphragm workpiece from the forming mold 2, thereby achieving the effect of facilitating the demolding of the diaphragm workpiece. The cooperation of the hot pressing module 4 and the heating coil 12 achieves the effect of pressing the diaphragm workpiece at the upper end of the forming mold 2. The material is heated and extruded to achieve the purpose of molding the raw material. During the heating and molding process of the raw material, heat enters the closed cavity 8 through the molding die 2 to evaporate the water inside the closed cavity 8, thereby pushing the sealing piston 7, and then the sealing piston 7 pushes the positioning rod 9 to move the pressure relief pipe 10 downward. At this time, air is sucked in through the setting of the one-way valve 11. During the continuous cooling process of the device, the evaporated water condenses into water. At this time, the sealing piston 7 is pulled back, and the sucked air is compressed through the pressure relief pipe 10 through the setting of the one-way valve 11, so that the air pushes the diaphragm workpiece and the molding die 2 to separate from each other, thereby achieving the effect of facilitating the rapid separation of the mold and the workpiece.

[0030] To sum up, with the help of the above-mentioned technical scheme of the utility model, the diaphragm is made and placed at the upper end of the molding mold, and the raw material is extruded through the setting of the hot pressing module, so that the raw material and the molding mold are fitted together, thereby achieving the effect of pressing and molding. At the same time, the pressure relief mechanism is heated by the heating coil inside the hot pressing module, so that the pressure relief mechanism moves and sucks air between the diaphragm workpiece and the molding mold. After the device is cooled, the pressure relief mechanism rebounds and pushes the air to separate the diaphragm workpiece from the molding mold, thereby achieving the effect of facilitating the demolding of the diaphragm workpiece.
