Description

Technical Field

[0001] This utility model relates to the field of set-top box processing technology, specifically to an injection mold for set-top box processing. Background Technology

[0002] A set-top box (STB), also known as a digital video converter box, is a device that connects a television set to an external signal source. It converts compressed digital signals into television content and displays it on the television. Signals can come from cable TV, satellite dishes, broadband networks, and terrestrial broadcasts. The casing of a set-top box is typically made using injection molding, and with the widespread use of set-top boxes, injection molding has become increasingly prevalent.

[0003] Because the bottom of the set-top box is open after molding, its outer edge abuts against the inner wall of the molding cavity, so it can only be lifted vertically upwards when it is removed. Moreover, there is no gripping point for picking up the set-top box, which makes it inconvenient to remove the set-top box. Therefore, it is necessary to propose an injection mold for the processing of set-top boxes. Utility Model Content

[0004] The purpose of this utility model is to provide an injection mold for set-top box processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a set-top box injection mold, comprising a processing table, a drive assembly installed inside the processing table, both ends of the drive assembly extending outside the processing table and connected to a moving plate, a molding cover fixedly installed on the moving plate, an injection port through the molding cover, a fixed cavity inside the processing table, a fixing hole on the upper cavity wall of the fixed cavity, a fixing rod slidably connected in the fixing hole, the lower end of the fixing rod extending into the fixed cavity and fixedly sleeved with a fixing block, a spring fixedly connected between the fixing block and the fixed cavity, a positioning groove on the processing table, a positioning hole through the fixing rod, and a positioning rod slidably connected in both the positioning hole and the positioning groove.

[0006] Preferably, the drive assembly includes a dual-head drive motor, the dual-head drive motor is mounted inside the processing table, and threaded rods are fixedly installed at both output ends of the dual-head drive motor. The threaded rods extend outside the processing table and are threadedly connected to threaded sleeves, which are fixedly sleeved on the moving plate.

[0007] Preferably, the threaded rod is rotatably connected to the outer wall of the processing table via a bearing.

[0008] Preferably, one end of the positioning rod extends outside the processing table, and the positioning rod is fixedly connected to the moving plate.

[0009] Preferably, the spring is sleeved on the wall of the fixed rod.

[0010] Preferably, the two molding covers together with the upper end of the processing table form a molding cavity, and the injection port is connected to the molding cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when in use, the driving component drives the molding cover to move and expose the set-top box, while driving the positioning rod to move and release the fixing rod and fixing block. At this time, the spring pushes the fixing block and fixing rod to rise, and the fixing rod pushes the shaped set-top box to rise, making it very simple and convenient to remove the set-top box.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-4 As shown, this utility model provides the following technical solution:

[0019] Example 1: A set-top box injection mold includes a processing table 1. A drive assembly is installed inside the processing table 1. Both ends of the drive assembly extend outside the processing table 1 and are connected to a moving plate 2. A molding cover 3 is fixedly installed on the moving plate 2. An injection port 15 is opened through the molding cover 3. A fixed cavity 4 is opened inside the processing table 1. A fixing hole 5 is opened on the upper cavity wall of the fixed cavity 4. A fixing rod 6 is slidably connected in the fixing hole 5. The lower end of the fixing rod 6 extends into the fixed cavity 4 and is fixedly sleeved with a fixing block 7. A spring 8 is fixedly connected between the fixing block 7 and the fixed cavity 4. A positioning groove 9 is opened on the processing table 1. A positioning hole 10 is opened through the fixing rod 6. A positioning rod 11 is slidably connected in both the positioning hole 10 and the positioning groove 9.

[0020] The drive assembly includes a dual-head drive motor 12, which is mounted inside the processing table 1. Both output ends of the dual-head drive motor 12 are fixedly mounted with threaded rods 13. The threaded rods 13 extend to the outside of the processing table 1 and are threadedly connected to threaded sleeves 14. The threaded sleeves 14 are fixedly sleeved on the moving plate 2.

[0021] In use, the molding cover 3 and the top of the processing table 1 together form a processing cavity. Material is then injected into the processing cavity through the injection port 15. After the material cools and solidifies, the dual-head drive motor 12 can be started. The dual-head drive motor 12 drives the threaded rod 13 to rotate. The threaded rod 13, through its cooperation with the threaded sleeve 14, drives the moving plate 2 to move outward. The moving plate 2 drives the molding cover 3 to move outward, exposing the molded set-top box. As the moving plate 2 moves, it also drives the positioning rod 11 to move synchronously, causing the positioning rod 11 to disengage from the positioning hole 10. The spring 8 pushes the fixed block 7 above the fixed block 7, thereby releasing the fixing rod 6 and the fixed block 7. At this time, the spring 8 pushes the fixed block 7 to rise, and the fixed block 7 pushes the fixed rod 6 to rise. The fixed rod 6 will push the set-top box to rise, thereby facilitating the removal of the set-top box. After the removal is completed, the fixed rod 6 can be pressed to reset the fixed rod 6 and the fixed block 7. Then, the dual-head drive motor 12 is started to drive the moving plate 2 and the forming cover 3 to reset. The moving plate 2 drives the positioning rod 11 to insert into the positioning hole 10, thereby positioning the fixed rod 6 and facilitating subsequent processing.

[0022] Example 2: The technical solutions in this example that differ from Example 1 include:

[0023] The threaded rod 13 is rotatably connected to the outer wall of the processing table 1 via a bearing, so that the processing table 1 supports the threaded rod 13 and the threaded rod 13 can only rotate in its original position. One end of the positioning rod 11 extends outside the processing table 1 and is fixedly connected to the moving plate 2, so that the moving plate 2 will drive the positioning rod 11 to move synchronously when it moves. The spring 8 is sleeved on the rod wall of the fixed rod 6. The two molding covers 3 and the upper end of the processing table 1 together form a molding cavity, and the injection port 15 is connected to the molding cavity. The molding cover 3 and the top of the processing table 1 together form a processing cavity. Then, the material is injected into the processing cavity through the injection port 15, and the set-top box is formed after the material cools and solidifies in the processing cavity.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
