[0002] A zirconia ceramic headphone housing refers to the outer shell part made of zirconia ceramic material for wrapping the internal components of the headphone. Zirconia ceramic has many excellent properties, such as high strength and high hardness, making the headphone housing firm and durable, and capable of effectively protecting the internal electronic components and acoustic structures. In the forming preparation of zirconia ceramic headphone housings, the dry pressing forming technology is also one of the commonly used technologies. The dry pressing forming technology uses external physical pressure to press ceramic powder into a solid of a certain shape, and has the advantages of precise production blank size, simple operation, and mechanized operation.

[0003] However, during the use of the dry pressing forming device in the existing forming preparation mold for zirconia ceramic headphone housings, when pouring dry powder into the mold, there will be scattered dry powder, and the scattered dry powder will adhere to the product during demolding, resulting in unsmooth demolding, and even possibly damaging the product or the mold.

[0030] A specific application of this embodiment is as follows: When in use, first place the device stably at the corresponding position through the support legs 104, pour the dry powder mixed with the adhesive required for processing into the lower mold 1, and then start the first motor 221 on the support plate 211. The first motor 221 drives the moving support plate one 213 to slide left and right in the trapezoidal chute two 214 through the first threaded rod 212. At this time, the cleaning roller 223 on the first rotating shaft 222 moves left and right under the mutual cooperation of the trapezoidal chute three 215 and the moving support plate one 213, so that the dry powder on the mold surface can be quickly and comprehensively cleaned, keeping the mold clean and providing good conditions for subsequent forming operations. By cleaning the dry powder in time, forming defects caused by dry powder residue, such as uneven surface and dimensional deviation, are avoided, thereby ensuring that the earphone housing has a high forming quality. While the cleaning roller 223 is translating, the cleaning roller 223 will rotate under the mutual cooperation of the first gear 224 on the first rotating shaft 222 and the rack 225, so that a larger range of the mold surface can be covered through rotational movement, ensuring the complete removal of dry powder in each corner and complex shape area. Rotation makes the cleaning force distribution more uniform, avoiding incomplete local cleaning, and helping to obtain consistent cleaning quality.

The second motor 323 drives the two second gears 322 to rotate through the second rotating shaft 321, thereby driving the threaded sleeve 311 to rotate and driving the second threaded rod 312 to rotate. When the second threaded rod 312 rotates, it will drive the upper mold 103 to slide downward in the trapezoidal chute one 102 on the U-shaped support frame 101, and stamp and form the dry powder mixed with the adhesive in the lower mold 1, so that the applied pressure can be evenly transmitted to the ceramic powder, promoting the close combination and forming of the powder, ensuring the reasonable distribution of the ceramic material in the mold to obtain uniform density and good performance.
