Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a loudspeaker mold structure. Background Technology

[0002] Speaker molds are specialized equipment used to produce various components for loudspeakers. They are typically made using injection molds. However, for speaker injection parts with unique structures, more complex injection molding processes are required, leading to higher mold manufacturing costs. This is especially true when lateral demolding is involved, as the part is difficult to remove from the mold. Speaker injection molding often uses continuous strip injection, and traditional straight-pull demolding methods can easily damage the finished product, affecting yield. Furthermore, demolding can cause strip misalignment, leading to jumping and shifting during subsequent long-distance continuous movement, resulting in uneven strip movement that requires timely correction to prevent jamming. This significantly impacts the efficiency of speaker injection part production. Utility Model Content

[0039] Example

[0040] Please refer to Figure 1-7As shown, this embodiment provides a speaker mold structure, including a mold body 100, a molding structure 200, a guide platform 300, and a guide structure 400. The mold body 100 includes an upper mold base 110 and a lower mold base 120. The guide platform 300 is located below the mold body 100. A plurality of guide structures 400 are installed on the guide platform 300 and distributed on both sides of the mold body 100. The molding structure 200 includes a side push plate 210 disposed on the lower mold base 120 and a first molding die disposed on the upper mold base 110. The first molding die 220 and the second molding die 230 are located on the lower mold base 120. The side push plate 210 is also provided with an inclined guide block 211 for pushing the side push plate 210 to slide. The side push plate 210 is slidably installed on one side of the first molding die 220 and the second molding die 230. The side push plate 210, the first molding die 220 and the second molding die 230 cooperate to perform injection molding on the material strip. The mold body 100 performs injection molding on the material strip through the molding structure 200. The guide table 300 and the guide structure 400 cooperate to guide and move the material strip.

[0041] As attached Figure 4 As shown, the first molding die 220 is provided with a plurality of first molding parts 240, the second molding die 230 is provided with a plurality of second molding parts 250, and the side push plate 210 is provided with a plurality of third molding parts 260. The first molding parts 240, the second molding parts 250 and the third molding parts 260 are arranged in groups in the molding structure 200. The first molding parts 240, the second molding parts 250 and the third molding parts 260 cooperate to form a molding space. The plurality of molding spaces can perform injection molding work on multiple material strip molding units at one time, which greatly improves the material strip injection molding production efficiency.

[0042] As attached Figure 3 As shown, the second molding die 230 is further provided with a sliding table 231 on one side for the side push plate 210 to slide, and the side push plate 210 moves linearly along the sliding table 231.

[0043] As attached Figure 4As shown, the side push plate 210 is further provided with a guide hole 212 that moves in conjunction with the inclined guide block 211. The inclined guide block 211 is installed in the upper mold base 110. The upper mold base 110 drives the inclined guide block 211 to move vertically and cooperate with the guide hole 212 of the side push plate 210 to push the side push plate 210 to move horizontally. The first molding part 240 and the second molding part 250 cooperate with the lower mold base 120 through the upper mold base 110. When the upper mold assembly moves down, it will drive the inclined guide block 211 installed below it to move downward. During the downward movement of the inclined guide block 211, it will cooperate with the guide hole 212 of the side push plate 210. In coordination, as the upper mold assembly continues to move downward, the inclined guide block 211 will push the side push plate 210 to move along the sliding table 231 provided on the second molding mold 230 into the mold until the third molding part 260 cooperates with the first molding part 240, the second molding part 250 and the third molding part 260 to form a molding space; when the injection molding is completed, the upper mold base 110 will drive the inclined guide block 211 to move upward during the upward movement. The upward-moving inclined guide block 211 will drive the side push plate 210 away from the material strip through the guide hole 212, making room for the material strip to move, so that the injected material strip can move.

[0044] As attached Figure 5 As shown, the material guiding structure 400 further includes a guide plate 410 and a guide cover plate 420 disposed above the guide plate 410. The guide plate 410 is disposed on the material guiding table 300. A long-distance guiding and limiting track is formed on the worktable surface of the material guiding table 300 by a plurality of guide plates 410 and guide cover plates 420, and the material belt can move continuously and stably along the long-distance guiding and limiting track.

[0045] As attached Figure 5 As shown, further, the bottom center of the guide cover plate 420 is provided with a sliding groove 411 installed on the guide plate 410, and the sides of the sliding groove 411 are provided with limiting grooves 412 for limiting the jumping of the material belt, and the bottom ends of the guide cover plate 420 are provided with first guide ramps 413.

[0046] As attached Figure 5 As shown, further, the guide plate 410 has a guide rail 421 in the middle for mounting the bottom of the guide cover plate 420. The guide rail 421 has movable grooves 422 on both sides. The movable grooves 422 are stepped to accommodate the material belt. The steps are provided with second guide ramps 423 on both sides to facilitate the horizontal movement of the material belt. The bottom surface of the movable groove 422 has second guide ramps 423 at both ends. The movable groove 422 has lateral guide ramps 424 at both ends. The guide rail 421 also has clearance holes 425 on both sides at one end. The clearance holes 425 allow the automatic walking turntable 320 to pass through, so that the automatic walking turntable 320 can interact with the material belt. The guide cover plate 420 has clearance holes 425 at corresponding positions to provide rotation space for the automatic walking turntable 320.

[0047] As attached Figure 6 As shown, further, the limiting groove 412 provided in the guide cover plate 420 and the movable groove 422 provided in the guide plate 410 form a limiting guide space. There is a gap between the bottom surfaces on both sides of the guide cover plate 420 and the movable groove 422 provided in the guide plate 410. The first guide ramp 413 provided in the guide cover plate 420, the second guide ramp 423 provided in the guide plate 410, and the lateral guide ramp 424 guide the material strip into the limiting guide space. Several material guiding structures 400 are horizontally laid on the material guiding platform 300, which can provide full coverage guidance for the material strip in injection molding production, so that it moves smoothly and evenly in the limiting guide space, avoiding jumping and deviation, improving the smoothness of the material strip during movement, reducing manual correction, and improving the material strip movement efficiency.

[0048] As attached Figure 1 As shown, the guide table 300 is further provided with an automatic walking turntable 320 that drives the material belt to move. The automatic walking turntable 320 is located below the clearance hole 425 provided in the guide plate 410. The top of the automatic walking turntable 320 is higher than the upper surface of the movable groove 422 provided in the guide plate 410. The automatic walking turntable 320 cooperates with the through hole provided in the material belt. The periodically rotating automatic walking turntable 320 drives the material belt to move, thereby enabling the material belt to achieve the effect of periodic movement in the forming structure 200.

[0049] As attached Figure 1 As shown, furthermore, guide plates 310 are provided on both sides of the guide platform 300. The guide plates 310 are arc-shaped. The arc-shaped guide structure 400 can make the material belt more gentle and smooth when it comes into contact with it, avoiding jamming and large jumping of the material belt, which would affect the material belt entering the guide structure 400.

[0050] When the speaker mold structure is working, the material strip first contacts the guide plate 310, and is limited and guided by the limiting and guiding space provided by the guiding structure 400. Under the pull of the automatic walking turntable 320, the material strip is guided to the mold body 100 by the guide plate 410 and the guide cover plate 420. After the side push plate 210, the first molding mold 220 and the second molding mold 230 of the molding structure 200 complete the injection molding, the speaker injection molded part is demolded by an external robot and / or an ejection device. After the speaker material strip is injected, it re-enters the limiting and guiding space. The automatic walking turntable 320 will rotate periodically to pull the material strip to move within the guiding structure 400.

[0051] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
