[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 This utility model provides a positioning component for manufacturing Bluetooth headset shells, the positioning component for manufacturing Bluetooth headset shells includes:

[0028] Mounting frame 1, a fixed template 2 is fixedly installed on the base plate of the mounting frame 1, and an electric hydraulic rod 11 is symmetrically installed on the top plate of the mounting frame 1. A movable template 3 is fixedly installed on the telescopic end of the electric hydraulic rod 11.

[0029] The control box 6 is installed on one side of the mounting bracket 1 and is electrically connected to the electric hydraulic rod 11;

[0030] Side clamping mechanism 4, used to limit the misalignment of the moving template 3, is mounted on the vertical plate of the mounting frame 1;

[0031] A pressing mechanism 5 is installed in the slide groove 201 of the fixed template 2. The pressing mechanism 5 includes two positioning plates 51, which are symmetrically arranged in the slide groove 201. A guide rod 52 is slidably installed on the positioning plate 51. A positioning vertical rod 53 is fixedly installed at the end of the guide rod 52 away from the positioning plate 51. A wedge block 54 is fixedly installed at the end of the positioning vertical rod 53 away from the guide rod 52. A pressing rod 55 is installed on the moving template 3. The bottom end of the pressing rod 55 has a side inclined surface 551 that contacts and engages with the inclined surface of the wedge block 54. A positioning groove 301 is opened on the moving template 3 to engage with the positioning vertical rod 53. A return spring 56 is sleeved on the guide rod 52.

[0032] The positioning vertical rod 53, the wedge block 54, the positioning groove 301 and the sliding groove 201 are all of equal width. One end of the reset spring 56 is fixedly connected to the positioning piece 51, and the other end of the reset spring 56 is fixedly connected to the positioning vertical rod 53.

[0033] It should be noted that during use, by adjusting the side clamping mechanism 4 to match the moving template 3, the moving template 3 moves more stably when the control box 6 controls the electric hydraulic rod 11 to drive the moving template 3 toward the fixed template 2 for mold closing. During the movement, when the side inclined surface 551 of the pressing rod 55 contacts the inclined surface of the wedge block 54, the wedge block 54 is driven to move the positioning vertical rod 53 in the positioning groove 301 as the mold closes and is pressed into place. The positioning vertical rod 53 is then pressed against one side of the positioning groove 301 to achieve mold closing anti-misalignment positioning. This improves the positioning accuracy of the mold closing and is beneficial to improving the injection molding quality of the Bluetooth headset. When the mold opens, the positioning vertical rod 53 automatically resets under the action of the return spring 56.

[0034] It is worth noting that in order to achieve anti-misalignment positioning of the positioning vertical rod 53 in the positioning groove 301, the travel distance of the positioning vertical rod 53 in the positioning groove 301 is equal to the groove length of the positioning groove 301, and both are set to be equal to the distance between the positioning rod 55 and the wedge block 54 pressed by the pressing rod 55. Thus, anti-misalignment positioning can be performed when the positioning vertical rod 53 is inserted into the positioning groove 301.

[0035] Furthermore, the pressing mechanism 5 is provided in two sets, and the two sets of pressing mechanisms 5 are symmetrically distributed based on the middle of the fixed template 2. In this way, the accuracy of the anti-misalignment platform positioning can be improved by using the symmetrically distributed pressing mechanism 5.

[0036] In the embodiments of this utility model, please refer to Figures 1 to 5The side clamping mechanism 4 includes a bidirectional threaded rod 41, which is rotatably mounted on the vertical plate of the mounting frame 1. Side clamping plates 42 are symmetrically threaded on the bidirectional threaded rod 41, and T-shaped feet 43 are symmetrically mounted on the side clamping plates 42. A T-shaped groove 101 is provided on the vertical plate of the mounting frame 1 to slide with the T-shaped feet 43. A servo motor 44 for driving the bidirectional threaded rod 41 to rotate is mounted on the mounting frame 1. The servo motor 44 is electrically connected to the control box 6.

[0037] It should be noted that when the side clamping mechanism 4 is in use, the control servo motor 44 drives the bidirectional threaded rod 41 to rotate. When rotating, the side clamping plate 42 and the T-shaped foot 43 are driven to slide along the T-shaped groove 101 until the distance between the two side clamping plates 42 is adapted to the width of the moving template 3.

[0038] In the embodiments of this utility model, please refer to Figures 1 to 5 The fixed template 2 is equipped with a lower template 21 for forming the shell of a Bluetooth headset, and the movable template 3 is equipped with an upper template 31 that matches the lower template 21.

[0039] It should be noted that the lower mold plate 21 and the upper mold plate 31 have molding cavities for the injection molding of Bluetooth headset shells, so that injection molding can be carried out when the mold is closed. In addition, both the lower mold plate 21 and the upper mold plate 31 are detachable, which makes it easy to replace different mold plates for injection molding in the future.

[0040] In the embodiments of this utility model, please refer to Figures 1 to 5 The fixed template 2 is fixedly installed with guide posts 22 at its four corners, and the movable template 3 is fitted with guide sleeves 32 at its four corners that slide in cooperation with the guide posts 22.

[0041] It should be noted that retaining the conventional mold guide structure further stabilizes the mold closing action and improves positioning accuracy.

[0042] The working principle of the positioning component for manufacturing Bluetooth headset shells provided by this utility model is as follows:

[0043] In use, the servo motor 44 drives the bidirectional threaded rod 41 to rotate. When rotating, the side clamping plate 42 and the T-shaped foot 43 slide along the T-shaped groove 101 until the distance between the two side clamping plates 42 is adjusted to match the width of the moving template 3. Thus, when the control box 6 controls the electric hydraulic rod 11 to drive the moving template 3 toward the fixed template 2 to close the mold, the movement of the moving template 3 is more stable. When moving, after the side inclined surface 551 of the pressing rod 55 contacts the inclined surface of the wedge block 54, when moving further, the wedge block 54 drives the positioning vertical rod 53 to move in the positioning groove 301 until the mold is closed and pressed into place. The positioning vertical rod 53 is pressed against one side of the positioning groove 301 to achieve mold closing anti-misalignment positioning. This improves the positioning accuracy of the mold closing and is beneficial to improving the injection molding quality of Bluetooth headsets.

[0044] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
