Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology for speaker module housings, and in particular to a mold for processing the sound outlet of speaker module housings. Background Technology
[0002] like Figure 1 As shown, in the prior art, the sound outlet 101 of the module housing 10 of some speaker modules is set at a large angle. Therefore, a slanted slider is required during the injection molding process of the module housing. Since the sound outlet of the module housing is thin and long, a thin protrusion is required at the end of the slanted slider.
[0003] During actual production, the applicant found that the inclined slider needs a certain amount of movement margin. Therefore, the size of the sliding channel of the inclined slider needs to be set slightly larger than the cross-sectional size of the inclined slider. That is, the inclined slider cannot be tightly fitted with the sliding channel. This causes the inclined slider to unexpectedly retreat and warp when the injection pressure is too high during the injection molding process. As a result, the molding size at the outlet of the module shell is often not up to standard, the product defect rate is high, and thin bumps are prone to breakage, so the mold needs to be repaired frequently. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a mold for processing the sound outlet of speaker module housing with high production yield and long service life.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mold for processing the sound outlet of a speaker module housing, comprising:
[0006] A rear mold base is provided with a forming groove, an upper pressure block, a lower pressure block, a slanted slider, and a shovel base assembly. The shovel base assembly is connected to the slanted slider to drive the slanted slider to slide. There is a sliding channel between the upper pressure block and the lower pressure block for the slanted slider to slide. One end of the slanted slider has a thin protrusion that protrudes relative to the end face of the slanted slider. When the slanted slider is in the first position, the thin protrusion extends into the forming groove from one side of the forming groove.
[0007] A front mold base, which cooperates with the rear mold base, and a shovel base assembly connected to the front mold base. The front mold base is provided with a stop post, the bottom end of which presses against the inclined slider in the first position.
[0008] Furthermore, the top of one end of the inclined slider is a top plane, the upper slope of the inclined slider connects to the top plane and forms an obtuse angle, the stop post has an inclined surface that contacts and engages with the upper slope, and the contact area between the stop post and the inclined slider is located close to the top plane.
[0009] Furthermore, the upper pressure block has an upper mating slope that mates with the upper inclined surface, and the upper pressure block is located on the side of the stop post away from the forming groove.
[0010] Furthermore, the pressing block has a lower mating slope that mates with the lower slope of the inclined slider, and the pressing block is correspondingly arranged with the stop post.
[0011] Furthermore, the front mold base and the rear mold base are rotatably connected.
[0012] Furthermore, the inclined slider includes a slider body and an insert embedded in the slider body, one end of the insert protruding relative to one end of the slider body to form the thin bump.
[0013] The beneficial effects of this utility model are as follows: Compared with the existing speaker module housing injection mold, this mold has a stop post added to the front mold base. After the front mold base and the rear mold base are closed, the stop post can tightly press against the inclined slider, so that the inclined slider will not move backward during the injection molding process of the module housing. This helps to ensure the dimensional accuracy of the sound outlet of the module housing and improve the yield rate of module housing production. Furthermore, at the moment of mold opening between the front mold base and the rear mold base, the presence of the stop post can effectively improve the jump phenomenon of the inclined slider and reduce the upward sway of the inclined slider. This prevents the thin protrusion at the end of the inclined slider from breaking or being damaged, which helps to extend the service life of the mold and improve the mass production of the module housing.

[0028] The rear mold base is provided with a forming groove 1, an upper pressure block 2, a lower pressure block 3, a slanted slider 4, and a shovel base assembly 5. The shovel base assembly 5 is connected to the slanted slider 4 to drive the slanted slider 4 to slide. There is a sliding channel between the upper pressure block 2 and the lower pressure block 3 for the slanted slider 4 to slide. One end of the slanted slider 4 has a thin protrusion 441 that protrudes relative to the end face of the slanted slider 4. When the slanted slider 4 is in the first position, the thin protrusion 441 extends into the forming groove 1 from one side of the forming groove 1.
[0029] A front mold base is provided, which cooperates with the rear mold base. The shovel base assembly 5 is connected to the front mold base. A stop post 6 is provided on the front mold base. The bottom end of the stop post 6 presses against the inclined slider 4 which is in the first position.
[0030] As can be seen from the above description, the beneficial effects of this utility model are as follows: Compared with the existing injection mold of speaker module housing 10, this mold has a stop post 6 added to the front mold base. After the front mold base and the rear mold base are closed, the stop post 6 can tightly press against the inclined slider 4, so that the inclined slider 4 will not move backward during the injection molding process of the module housing 10, which helps to ensure the dimensional accuracy of the sound outlet 101 of the module housing 10 and improve the yield rate of the module housing 10 production; and, at the moment of mold opening of the front mold base and the rear mold base, due to the presence of the stop post 6, the jumping phenomenon of the inclined slider 4 can be effectively improved, and the upward swing amplitude of the inclined slider 4 can be reduced, so that the thin protrusion 441 at the end of the inclined slider 4 will not break or be damaged, which helps to extend the service life of the mold and improve the mass production of the module housing 10.
[0031] Furthermore, the top of one end of the inclined slider 4 is a top plane 41, the upper slope surface 42 of the inclined slider 4 connects to the top plane 41 and forms an obtuse angle, the stop post 6 has an inclined surface 61 that contacts and cooperates with the upper slope surface 42, and the contact area between the stop post 6 and the inclined slider 4 is set close to the top plane 41.
[0032] Furthermore, the upper pressure block 2 has an upper mating slope that mates with the upper inclined surface 42, and the upper pressure block 2 is located on the side of the stop post 6 away from the forming groove 1.
[0033] Furthermore, the lower pressure block 3 has a lower mating slope that mates with the lower slope of the inclined slider 4, and the lower pressure block 3 is correspondingly arranged with the stop post 6.
[0034] As can be seen from the above description, under the pressing action of the stop post 6, the lower slope of the inclined slider 4 can tightly press against the lower mating slope of the lower pressure block 3, thereby enabling the inclined slider 4 to be better fixed.
[0035] Furthermore, the front mold base and the rear mold base are rotatably connected.
[0036] As can be seen from the above description, during the rotation of the front mold base relative to the rear mold base, the shovel base assembly 5 drives the inclined slider 4 to slide.
[0037] Furthermore, the inclined slider 4 includes a slider body 43 and an insert 44 embedded in the slider body 43, one end of the insert 44 protruding relative to one end of the slider body 43 to form the thin protrusion 441.
[0038] As can be seen from the above description, the insert 44 is made of a metal material with high toughness, which can extend the service life of the mold to a greater extent.
[0039] Please refer to Figures 2 to 4Embodiment 1 of this utility model is as follows: A mold for processing the sound outlet of a speaker module housing includes a rear mold base and a front mold base. The rear mold base is provided with a forming groove 1, an upper pressing block 2, a lower pressing block 3, a slanted slider 4, and a spade base assembly 5. The forming groove 1 is used to form the module housing 10 of the speaker module. The module housing 10 has an inclined sound outlet 101. The spade base assembly 5 is connected to the slanted slider 4 to drive the slanted slider 4 to slide between a first position and a second position. A sliding channel for the slanted slider 4 to slide is provided between the upper pressing block 2 and the lower pressing block 3. One end of the slanted slider 4 has a protrusion relative to the end face of the slanted slider 4. Thin protrusion 441 is used to form the sound outlet 101 of the module housing 10. When the inclined slider 4 is in the first position, the thin protrusion 441 extends into the forming groove 1 from one side. The front mold base cooperates with the rear mold base. The shovel base assembly 5 is connected to the front mold base. The front mold base is provided with a stop post 6. The bottom end of the stop post 6 presses against the inclined slider 4 in the first position. During the opening and closing of the front mold base and the rear mold base, the front mold base drives the shovel base assembly 5 to move so as to drive the inclined slider 4 to slide from the first position to the second position, or from the second position to the first position.
[0040] The top of one end of the inclined slider 4 is a top plane 41. The upper inclined surface 42 of the inclined slider 4 connects to the top plane 41 and forms an obtuse angle. The stop post 6 has an inclined surface 61 that contacts and cooperates with the upper inclined surface 42. The contact area between the stop post 6 and the inclined slider 4 is located close to the top plane 41.
[0041] The upper pressure block 2 has an upper mating slope that mates with the upper inclined surface 42, and the upper pressure block 2 is located on the side of the stop post 6 away from the forming groove 1.
[0042] The lower pressure block 3 has a lower mating slope that mates with the lower slope of the inclined slider 4, and the lower pressure block 3 is correspondingly arranged with the stop post 6.
[0043] In this embodiment, the front mold base and the rear mold base are rotatably connected. In other embodiments, the front mold base and the rear mold base can be separated.
[0044] Optionally, the inclined slider 4 includes a slider body 43 and an insert 44 embedded in the slider body 43, one end of the insert 44 protruding relative to one end of the slider body 43 to form the thin protrusion 441. In this embodiment, the insert 44 is a thin steel sheet.
[0045] In summary, the mold for processing the sound outlet of a speaker module housing provided by this utility model, compared with existing speaker module housing injection molds, has a stop post added to the front mold base. After the front and rear mold bases are closed, the stop post can tightly press against the inclined slider, so that the inclined slider will not move backward during the injection molding process of the module housing, which helps to ensure the dimensional accuracy of the sound outlet of the module housing and improve the yield rate of module housing production. Furthermore, at the moment of mold opening between the front and rear mold bases, the presence of the stop post can effectively improve the jump phenomenon of the inclined slider and reduce the upward sway of the inclined slider, thereby preventing the thin protrusion at the end of the inclined slider from breaking or being damaged, which helps to extend the service life of the mold and improve the mass production of the module housing.
