Description

Technical Field

[0001] This utility model relates to the field of aviation headphone processing technology, and in particular to a glue injection mechanism for aviation headphone shells. Background Technology

[0002] Aviation headsets are head-mounted devices designed specifically for pilots, primarily for communication and hearing protection, while also providing a high-quality audio experience and long-term wearing comfort.

[0003] The aviation headset includes a set of shell support components. This set of support components is a set of two. In the traditional way, when manufacturing it, it is usually necessary to design two sets of molds for injection molding, which requires two sets of support equipment and injection molding equipment. This results in the reuse of too many parts and the need for injection molding on both sides, which affects the rationality of the device's use.

[0004] Therefore, we provide a glue-applying mechanism for aircraft headphone housings. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a glue injection mechanism for aviation headphone shells, achieving the effect of simultaneous injection molding of both shells.

[0006] In view of this, the present invention provides a glue injection mechanism for an aviation headphone shell, including a lower mold, an upper mold, and a guide support mechanism and an injection support mechanism disposed between the lower mold and the upper mold.

[0007] The guiding support mechanism includes a central guide plate, a limiting guide rail, a forming support plate, a central moving column, side guide blocks, a moving guide frame, and a forming support column. The central guide plate is located between the upper mold and the lower mold, and the forming support plate is located between the central guide plate and the lower mold. The limiting guide rail is opened on the upper surface of the central guide plate. The side guide blocks are slidably disposed inside the limiting guide rail. The central moving column is provided with side guide blocks on both opposite sides. The moving guide frame is installed on the front end surface of the central moving column and is slidably connected to the forming support column.

[0008] The injection support mechanism includes an injection cylinder, an injection tube, and a guide tube. The lower end of the injection cylinder is installed in the middle of the injection tube, and the guide tube is installed on the lower surfaces of both opposite ends of the injection tube.

[0009] Preferably, the inner wall of the limiting guide rail has guide grooves with different inclination angles on both sides, and the two side guide blocks are respectively slidably disposed inside the guide grooves on both sides of the limiting guide rail. The limiting guide rail is in an inclined state as a whole, and the central moving column is slidably disposed at the lower end of the inner wall of the limiting guide rail.

[0010] Preferably, the guide support mechanism further includes a cylinder for driving the support, a support block is inserted into the output end of the cylinder, and the central moving column is installed at the output end of the cylinder, and the cylinder, the support block and the central moving column are in the same inclined state.

[0011] Preferably, the forming support column is inclined in the same way as the central moving column. Two inclined grooves are opened on the outer side of the forming support column, and the inclination angles of the two inclined grooves are different. The inclination angles of the two inclined grooves are the same as the inclination angles of the side guide blocks on both sides. The inclination angles of the guide parts on both sides inside the moving guide frame are different.

[0012] Preferably, the injection tube is S-shaped, and the two guide tubes are located at the front and rear ends of the S-shape, respectively, and the two guide tubes are used for injection support of a group of products.

[0013] Preferably, the movable guide frame is located at one corner of the S-shape inside the injection molding tube, and the angle at the other S-shaped corner inside the injection molding tube is greater than the angle at one corner of the movable guide frame.

[0014] Preferably, the injection cylinder is inserted into the central guide plate and the upper mold, and the injection cylinder extends to the outside of the upper mold.

[0015] Compared with the prior art, this utility model provides a glue-feeding mechanism for aviation headphone shells, which has the following beneficial effects:

[0016] 1. This utility model, through the combined use of a guide support mechanism and an injection support mechanism, ensures the accuracy of product molding and the safety of demolding during product preparation.

[0017] 2. This utility model ensures the stability and smoothness of the movement of the connecting components of the cylinder during driving operation and guiding support by setting the tilt angles of the entire limiting guide rail, cylinder, support block, central moving column, moving guide frame, and forming support column to be consistent, thereby improving the stability and accuracy of its movement.

[0018] 3. This utility model sets the components on the same side of the guide support mechanism at the same tilt angle, so that the whole structure has two tilt angles. Thus, when the moving guide frame moves horizontally, the forming pillar gradually moves from the lower position to the higher position of the moving guide frame, and the forming pillar is gradually pulled upward, so that it moves outward of the product at a fixed angle, ensuring the stability of the separation angle between the forming pillar and the product, and improving the stability of the product after demolding.

[0019] 4. This utility model, by setting the injection tube to an S-shape, allows its side to avoid the running position of the moving guide frame within a minimum angle, ensuring accurate and stable guiding movement of the device and the operation of each stroke during injection molding. With the support of the injection tube itself, it ensures uniform and stable material flow when simultaneously injecting components on both sides.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1: A glue-applying mechanism for an aviation headphone shell, such as... Figures 1-4As shown, it includes a lower mold 1, an upper mold 2, and a guide support mechanism and an injection support mechanism disposed between the lower mold 1 and the upper mold 2.

[0029] The guiding support mechanism includes a central guide plate 3, a limiting guide rail 301, a forming support plate 4, a central moving column 602, side guide blocks 603, a moving guide frame 604, and a forming support column 605. The central guide plate 3 is located between the upper mold 2 and the lower mold 1, and the forming support plate 4 is located between the central guide plate 3 and the lower mold 1. The limiting guide rail 301 is opened on the upper surface of the central guide plate 3. The side guide blocks 603 are slidably disposed inside the limiting guide rail 301. The central moving column 602 is provided with side guide blocks 603 on both sides. The moving guide frame 604 is installed on the front surface of the central moving column 602 and is slidably connected to the forming support column 605.

[0030] The injection support mechanism includes an injection cylinder 5, an injection tube 501, and a guide tube 502. The lower end of the injection cylinder 5 is installed in the middle of the injection tube 501, and guide tubes 502 are installed on the lower surfaces of both ends of the injection tube 501.

[0031] Firstly, based on the clamping guidance of the lower mold 1 and the upper mold 2, the precise position of the internal guide support mechanism and the injection support mechanism is ensured. This allows the guide support mechanism to accurately provide guiding movement, enabling the injection support mechanism to perform accurate injection molding. With the simultaneous guidance of the two side guide tubes 502, the device ensures the accurate and reliable simultaneous injection molding of the two sides of the earphone shell components. Under the positioning guidance of the limit guide rail 301, the side guide block 603 and the central moving column 602 can accurately tilt and move. With the simultaneous guidance of the moving guide frame 604 on the molding pillar 605, the molding pillar 605 can tilt and move, ensuring the accuracy and safety of the product molding below the molding pillar 605. This prevents breakage at the connection between the molding pillar 605 and the product below during normal vertical demolding. Thus, the combined use of the guide support mechanism and the injection support mechanism ensures the accuracy of product molding and the safety of demolding.

[0032] like Figures 1-4 As shown, the inner wall of the limiting guide rail 301 has guide grooves with different inclination angles on both sides, and two side guide blocks 603 are slidably disposed inside the guide grooves on both sides of the limiting guide rail 301. The limiting guide rail 301 is in an inclined state, and the central moving column 602 is slidably disposed at the lower end of the inner wall of the limiting guide rail 301.

[0033] The guide support mechanism also includes a cylinder 6 for driving the support. A support block 601 is inserted into the output end of the cylinder 6, and a central moving column 602 is installed at the output end of the cylinder 6. The cylinder 6, the support block 601 and the central moving column 602 are in the same inclined state.

[0034] The forming support column 605 is inclined in the same way as the central moving column 602. Two inclined grooves are opened on the outer side of the forming support column 605, and the inclination angles of the two inclined grooves are different. The inclination angles of the two inclined grooves are the same as the inclination angles of the side guide blocks 603 on both sides. The inclination angles of the guide parts on both sides inside the moving guide frame 604 are different.

[0035] By setting the tilt angles of the entire limiting guide rail 301, cylinder 6, support block 601, central moving column 602, moving guide frame 604, and forming pillar 605 to be consistent, the stability and smoothness of the overall movement angle of the connecting parts of the cylinder 6 during driving and guiding support are ensured, thus improving the stability and accuracy of its movement. Furthermore, by setting the angles of the two sides of the inner wall of the limiting guide rail 301 to be inconsistent, the angles of the two side guide blocks 603 to be inconsistent, the angles of the guide positions on both sides of the moving guide frame 604 to be inconsistent, and the tilt angles of the two inclined grooves of the forming pillar 605 to be inconsistent, and setting the tilt angles of the components on the same side of the guiding support mechanism to be consistent, the entire structure presents two tilt angles. Thus, under the tilt angle of the moving guide frame 604 itself, during its translation, the forming pillar 605 gradually moves from a lower position to a higher position, causing the forming pillar 605 to be gradually pulled upward, thereby moving it outward from the product at a fixed angle. This ensures the stability of the separation angle between the forming pillar 605 and the product, improving the stability of the product after demolding.

[0036] Example 2: A glue-applying mechanism for an aviation headphone shell, such as... Figures 1-4 As shown, the injection tube 501 is S-shaped, and two guide tubes 502 are located at the front and rear ends of the S-shape, respectively. The two guide tubes 502 are used for injection support of a group of products.

[0037] The movable guide frame 604 is located at one corner inside the S-shape of the injection tube 501, and the angle at the other S-shaped corner inside the injection tube 501 is greater than the angle at one corner of the movable guide frame 604.

[0038] By setting the injection tube 501 to an S-shape, its side can avoid the running position of the moving guide frame 604 within the minimum angle, ensuring the accurate and stable operation of the device's guiding movement and each stroke during injection. With the support of the injection tube 501 itself, it ensures the uniform and stable material flow when simultaneously injecting components on both sides, thereby improving the accuracy and efficiency of the device's injection.

[0039] like Figures 1-4 As shown, the injection cylinder 5 is inserted into the middle guide plate 3 and the upper mold 2, and the injection cylinder 5 extends to the outside of the upper mold 2.

[0040] With the dual guidance and limiting of the central guide plate 3 and the upper mold 2, the safety of the entire device during injection molding is ensured, and the stability of the injection cylinder 5's position during injection molding is improved.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
