Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a low dielectric constant 5G mobile phone antenna injection molding bracket. Background Technology

[0002] Low-dielectric-constant 5G mobile phone antennas are made of materials with low dielectric constant, effectively improving the performance and stability of 5G communication. Low dielectric constant and low dielectric loss reduce signal attenuation and distortion, enhancing communication quality and stability. By optimizing material properties, low-dielectric-constant 5G mobile phone antennas provide a more efficient and stable signal transmission solution for 5G communication.

[0003] Currently, the production of low dielectric constant 5G mobile phone antennas requires injection molding, which necessitates the use of an injection molding bracket to hold the upper and lower molds in the injection molding device. However, with existing injection molding brackets, after the low dielectric constant 5G mobile phone antenna is injection molded, the upper and lower molds must be separated first, and then the molded low dielectric constant 5G mobile phone antenna must be manually removed. It is not possible to automatically remove the low dielectric constant 5G mobile phone antenna at the same time as the upper and lower molds are separated, which is cumbersome, has poor performance, and reduces the practicality of the device. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background technology by proposing a low dielectric constant 5G mobile phone antenna injection molding bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low dielectric constant 5G mobile phone antenna injection molding bracket, comprising:

[0007] Fixture;

[0008] The upper mold is fixedly installed on the fixed frame by connecting blocks. The bottom of the upper mold has multiple semi-circular upper mold slots. Each semi-circular upper mold slot has a circular limiting plate fixedly installed symmetrically front and back. The top of each semi-circular upper mold slot is fixedly connected to an injection tube, and the injection tube is fixedly extended through the top of the upper mold.

[0009] The lower mold is movably installed in the fixed frame via a lifting assembly, and the lower mold is positioned directly below the upper mold. The top of the lower mold is rotatably fitted with multiple semi-circular tubular mold hoppers.

[0010] A flipping assembly is used to drive each semi-circular tubular mold bucket to flip simultaneously.

[0011] Preferably, the flipping assembly includes brackets symmetrically fixedly installed on the front side of the lower mold, a rotating shaft is rotatably installed between the two brackets, a gear is coaxially fixedly installed at the end of the rotating shaft, a rack meshes with the rear side of the gear, and the lower end of the rack is fixedly installed on the fixed frame, and multiple connecting frames are fixedly fitted on the surface of the rotating shaft, and the multiple connecting frames are respectively fixed to the bottom of multiple semi-circular tubular mold hoppers.

[0012] Preferably, the lifting assembly includes a drive motor fixedly installed on the top of the fixed frame. The drive end of the drive motor is vertically downward and fixedly installed with a lead screw. The surface of the lead screw is threadedly connected to a lifting plate, and the lifting plate slides through the surface of the fixed frame and is fixed to the surface of the lower mold.

[0013] Preferably, the top of the lower mold has multiple semi-circular lower mold grooves, and the semi-circular lower mold grooves match the semi-circular tubular mold hopper.

[0014] Preferably, the side of the fixing frame is provided with a sliding hole, and the sliding hole is slidably connected to the lifting plate.

[0015] Compared with existing technologies, the advantages of the low dielectric constant 5G mobile phone antenna injection molding bracket provided by this utility model are as follows:

[0016] This invention controls the rotation of the lead screw by a drive motor, and uses a lifting plate to move the lower mold downward. When the gear and rack mesh, the rotating shaft drives each semi-circular tubular mold hopper to tilt outward and forward, thus automatically emptying the low dielectric constant G mobile phone antenna product from each semi-circular tubular mold hopper. This achieves automatic unloading of the low dielectric constant G mobile phone antenna product, which is convenient, fast, and improves the practicality of the device. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1 to 4 A low dielectric constant 5G mobile phone antenna injection molding bracket, comprising:

[0024] The upper mold 2 is fixedly installed on the fixed frame 1 via a connecting block 3. The bottom of the upper mold 2 has multiple semi-circular upper mold grooves 4. Each semi-circular upper mold groove 4 has a circular limiting plate 5 fixedly installed symmetrically in front and behind. The top of each semi-circular upper mold groove 4 is fixedly connected to an injection tube 6, and the injection tube 6 is fixedly extended through to the top of the upper mold 2.

[0025] The lower mold 7 is movably installed in the fixed frame 1 via a lifting assembly. The lifting assembly includes a drive motor 16 fixedly installed on the top of the fixed frame 1. The drive end of the drive motor 16 is vertically downward and fixedly installed with a lead screw 14. The surface of the lead screw 14 is threadedly connected to a lifting plate 15. The lifting plate 15 slides through the surface of the fixed frame 1 and is fixed to the surface of the lower mold 7. A sliding hole 18 is provided on the side of the fixed frame 1, and the sliding hole 18 is slidably connected to the lifting plate 15, which serves to limit the movement of the lifting plate 15. When the drive motor 16 controls the lead screw 14 to rotate, it can drive the lifting plate 15 to move the lower mold 7 vertically along the sliding hole 18.

[0026] Furthermore, the lower mold 7 is placed directly below the upper mold 2, and multiple semi-circular tubular mold hoppers 8 are rotatably embedded on the top of the lower mold 7. Multiple semi-circular lower mold grooves 17 are opened on the top of the lower mold 7, and the semi-circular lower mold grooves 17 match the semi-circular tubular mold hoppers 8.

[0027] The flipping assembly is used to drive each semi-circular tubular mold 8 to flip simultaneously. The flipping assembly includes brackets 9 symmetrically fixedly installed on the front side of the lower mold 7. A rotating shaft 10 is rotatably installed between the two brackets 9. A gear 11 is coaxially fixedly installed at the end of the rotating shaft 10. A rack 13 meshes with the rear side of the gear 11. The lower end of the rack 13 is fixedly installed on the fixed frame 1. Multiple connecting frames 12 are fixedly fitted on the surface of the rotating shaft 10. The multiple connecting frames 12 are respectively fixed to the bottom of the multiple semi-circular tubular mold 8.

[0028] The working principle of this utility model is as follows:

[0029] In use, the molten material for preparing the low dielectric constant 5G mobile phone antenna is first injected sequentially through each injection tube 6 into each semi-circular upper mold groove 4 and semi-circular tubular mold hopper 8 and the corresponding two circular limiting plates 5, and then cooled and shaped.

[0030] After the low dielectric constant 5G mobile phone antenna product is formed, the drive motor 16 is started to control the lead screw 14 to rotate. The lifting plate 15 drives the lower mold 7 to move down. When the gear 11 meshes with the rack 13, the rotating shaft 8 drives each semi-circular tubular mold hopper 8 to flip outward and forward to tilt, so that the low dielectric constant 5G mobile phone antenna product in each semi-circular tubular mold hopper 8 can be automatically poured out. This realizes the automatic unloading of the low dielectric constant 5G mobile phone antenna product, which is convenient and fast and improves the practicality of the device.

[0031] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0032] 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.
