Description

Technical Field

[0001] This invention relates to the field of injection mold technology, specifically to an injection mold for a speaker shell. Background Technology

[0002] Injection molds play a vital role in modern industrial production. The cavity and core inside the mold are designed according to the shape and size of the desired product. When molten raw material is injected into the mold, it fills the mold cavity and solidifies into a product that conforms to the shape of the mold cavity after cooling. Products produced by injection molds have consistency and stability and good quality, so they are widely used in various production fields.

[0003] When injection molding, dividing the product into sections allows for more precise control over material usage, shortens the injection cycle, and makes it easier for the product to be ejected from the mold after cooling and solidification.

[0004] When using segmented injection molding to produce speaker housings, the clamping requirements for different areas of the speaker housing vary, and the differential clamping of different areas of the mold is not precise enough. This can lead to insufficient strength in certain areas of the product, resulting in defects such as deformation and cracks, which affect the performance of the product.

[0034] Please see Figure 1-9 A speaker shell injection mold includes an upper sealing plate 1 and a female mold plate 2. The female mold plate 2 is located at the lower end of the upper sealing plate 1. A first mold core 3 and a second mold core 4 are located inside the female mold plate 2. A male mold system 5 is bolted to the lower end of the female mold plate 2. A mold foot 6 is bolted to the lower end of the male mold system 5. An ejector plate 7 is slidably connected to the inner side of the mold foot 6. A lower fixing plate 8 is located at the lower end of the ejector plate 7. The male mold system 5 includes a male mold plate 51. A cooling water channel 52 is fixedly connected through the inner side of the male mold plate 51. A side clamping assembly 53, a hydraulic clamping assembly 54, and an electric clamping assembly 55 are installed inside the male mold plate 51. (Reference) Figure 1 and Figure 2 During the use of the device, first use a cleaning agent and a soft cloth to clean the surface of each component of the device. Then, attach the first mold core 3 and the second mold core 4 to the upper end of the male mold system 5 respectively. Next, cover the female mold plate 2 to ensure that the female mold plate 2 covers the first mold core 3 and the second mold core 4 at the same time. Then, align the injection hole on the upper sealing plate 1 with the injection hole on the female mold plate 2 and place the upper sealing plate 1 on the female mold plate 2. This can ensure that no dust, oil stains or other impurities adhere to the device components, thereby ensuring the cleanliness of the injection molding environment.

[0035] Please see Figure 1-9 In one embodiment, the inner side of the mother template 2 is fitted to the outer side of the first mold core 3, and the inner side of the mother template 2 is fitted to the outer side of the second mold core 4. The top surfaces of the first mold core 3 and the second mold core 4 are on the same horizontal plane. (Reference) Figure 1 and Figure 2 A certain amount of raw material is injected into the mold cavities of the first mold core 3 and the second mold core 4 through the injection holes on the upper sealing plate 1 and the mother mold plate 2. The mold flow channel and outlet are observed to ensure that they are unobstructed. After confirming that the device is in good production condition, the injection molding of the speaker shell is started. This ensures the accuracy of the injection molding process and achieves better injection molding effect.

[0036] Please see Figure 1-9 In one embodiment, the outer side of the cooling water channel 52 is fitted to the inner side of the first mold core 3. Two hydraulic clamping assemblies 54 are provided, symmetrically distributed. Two electric clamping assemblies 55 are also provided, symmetrically distributed. (Reference) Figure 3The cooling water channel 52 not only dissipates heat but also helps to position the device during assembly. This design is more reasonable and can achieve better clamping effect during product manufacturing, thus ensuring product quality.

[0037] Please see Figure 1-9 In one embodiment, the side clamping assembly 53 includes a side fixing seat 531. A side servo motor 532 is fixedly connected to the inner side of the side fixing seat 531 by bolts. A square-headed hydraulic rod 533 is fixedly connected to the outer side of the main shaft of the side servo motor 532. A positioning block 534 is slidably connected to the outer side of the square-headed hydraulic rod 533. An inter-block groove 535 is formed on the inner side of the positioning block 534. A side pressure block 536 is installed on one side of the positioning block 534. The central axis of the side servo motor 532 and the central axis of the square-headed hydraulic rod 533 are on the same straight line. The outer side of the square-headed hydraulic rod 533 is in contact with the inner side of the inter-block groove 535. The included angle between the square-headed hydraulic rod 533 and the side pressure block 536 is 90°. (Reference) Figure 4 and Figure 5 The AC servo motor 551 is started by controlling the electrical signal, which drives the sliding rod 552 to slide inside the inner block 553 and push the inclined pressure block 554, so that the moving block 556 drives the inner rod 557 to abut against the first mold core 3. This design is conducive to the cooperation between components and avoids obstruction between components.

[0038] Please see Figure 1-9 In one embodiment, the hydraulic clamping assembly 54 includes a hydraulic motor 541, an oil pipe 542 mounted on the upper end of the hydraulic motor 541, a rod head 543 fixedly connected to the outer side of the main shaft of the hydraulic motor 541, a locking seat 544 mounted on one side of the hydraulic motor 541, an electric lock 545 mounted on the upper end of the locking seat 544, a locking clamping block 546 provided inside the locking seat 544, a locking groove 547 formed inside the locking clamping block 546, and a limit rod 548 mounted inside the locking clamping block 546. The angle between the oil pipe 542 and the hydraulic motor 541 is 90°. The oil pipe 542 is U-shaped. The rod head 543 and the hydraulic motor 541 are on the same axis. There are two electric locks 545, which are centrally symmetrically distributed on the upper end of the locking seat 544. The rod head 543 is slidably connected to the inner side of the locking groove 547. The angle between the rod head 543 and the locking pressing block 546 is 90°. The outer side of the limit rod 548 is in contact with the outer side of the electric lock 545. (Reference) Figure 6 and Figure 7When the two hydraulic clamping assemblies 54 are performing the pressing operation, the amount of oil entering the hydraulic motor 541 from the oil pipe 542 is controlled by pressing the button on the throttle valve at the end of the oil pipe 542 away from the main shaft of the hydraulic motor 541, thereby adjusting the pressure generated by the hydraulic motor 541. The check valve in the oil pipe 542 near the main shaft of the hydraulic motor 541 can effectively prevent the hydraulic oil in the hydraulic clamping assembly 54 from flowing back, ensuring the stability of the clamping force of the hydraulic motor 541. When the main shaft of the hydraulic motor 541 moves, it will drive the rod head 543 to move and squeeze the locking clamping block 546. When the locking clamping block 546 is squeezed... When the pressure moves, the limit rod 548 will no longer rotate. Now, the limit rod 548 will rotate due to the elastic force provided by the electric lock 545 and engage with another electric lock 545. At this time, the limit rod 548 and the locking groove 547 will restrict the rod head 543 together, playing a locking function, ensuring that the rod head 543 abuts against the locking block 546, so that the locking block 546 generates a stable clamping force on the second mold core 4, thereby providing a high clamping force to ensure the tight closure of the mold, which is convenient for the injection molding production of the front part of the speaker shell. This design is conducive to the transmission of force between components and improves the operating efficiency of the device.

[0039] Please see Figure 1-9 In one embodiment, the electric clamping assembly 55 includes an AC servo motor 551. A sliding rod 552 is fixedly connected to the lower end of the main shaft of the AC servo motor 551. An inner locking block 553 is installed on the outer side of the sliding rod 552. An inclined pressing block 554 is slidably connected to the inner side of the inner locking block 553. A limit fixing seat 555 is installed on the outer side of the inner locking block 553. A moving block 556 is installed on one side of the limit fixing seat 555. A stop rod 557 is fixedly connected to the inner side of the moving block 556 by bolts. One end of the stop rod 557 is provided with The device features an arc-shaped groove 558. The AC servo motor 551 and the sliding rod 552 are on the same axis. The angle between the sliding rod 552 and the inner locking block 553 is 90°. The outer side of the inner locking block 553 is in contact with the inner side of the limiting fixing seat 555. The bottom surface of the limiting fixing seat 555 and the bottom surface of the moving block 556 are on the same horizontal plane. Two abutment rods 557 are provided, symmetrically distributed inside the moving block 556. The number of arc-shaped grooves 558 corresponds to the number of abutment rods 557. (Reference) Figure 8 and Figure 9 When the two electric clamping components 55 are performing the pressing operation, the side servo motor 532 is started by controlling the electrical signal, which drives the square-headed hydraulic rod 533 to slide inside the inter-block groove 535, so that the other end of the square-headed hydraulic rod 533 abuts against the side pressure block 536, thereby pressing one side of the first mold core 3. Due to the control of the electrical signal, it has a fast response speed, which can ensure the consistency of the clamping force in all directions during the pressing process, and reduce the product quality caused by parameter fluctuations. This design can improve the wedge fit between components and further improve the mold quality.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
