Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a set-top box shell mold. Background Technology

[0002] A set-top 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, allowing users to watch digital television programs on their existing television sets and engage in interactive digital entertainment, education, and commercial activities via the internet. It is a commonly used smart device in modern society. An essential component in the production of set-top boxes is the set-top box casing. Due to the special nature of the set-top box casing, it is generally produced using molds.

[0003] In existing set-top box casing molds, the cylinder stroke accuracy tends to change after prolonged use, causing the ejector end to not fully retract into the ejector box during injection molding, resulting in dents in the molded set-top box casing. Secondly, the mold requires an additional cooling system to lower the temperature and accelerate the molding speed of the injection molten liquid. However, the temperature of the existing cooling water gradually increases after prolonged use, leading to poor cooling effect and prolonging the molding time of the injection molten liquid. Therefore, a new set-top box casing mold is proposed. Utility Model Content

The threaded pins 220 penetrate the inner plate 230, and are fixed to the inner plate 230 by threaded connections. The support legs 210 provide stable support for the equipment during operation, ensuring the equipment's stability. The stable operation of the equipment, and due to the stability of the threaded connection, enhances the connection stability between the built-in plate 230 and the support leg 210, while also allowing the support leg 210 to be connected using the built-in plate 230, thereby ensuring the connection stability of the equipment. The cooling component 300 includes a cooling water tank 310 disposed at the top of the built-in plate 230, a mounting frame 320 disposed at the top of the cooling water tank 310, heat dissipation fins 330 disposed on the inner wall of the mounting frame 320, and a connecting water pipe 340 disposed on the inner wall of the heat dissipation fins 330. The movable mold 500 includes a first fixing plate 510 disposed on the other side of the operating table 100, a drive pump 520 mounted on the outer wall of the first fixing plate 510, and a pump rod 5 on the side of the first fixing plate 510 away from the drive pump 520. At one end of pump rod 530, a movable plate 550 is installed at the other end. A positioning rod 540 is installed on the outer wall of the movable plate 550. A pump mounting bracket 400 is provided on the outer wall of the operating table 100. The other end of the pump mounting bracket 400 contacts the drive pump 520. The first fixed plate 510 and the second fixed plate 610 are on the same horizontal plane. The first fixed plate 510 and the positioning rod 540 are slidably connected. When the equipment is working, the pump mounting bracket 400 can support the drive pump 520 to ensure stable operation. The drive pump 520 and pump rod 530 are integrated, allowing the drive pump 520 to directly drive the positioning rod 540 to slide within the first fixed plate 510 during operation, thus fixing the mold 60. The device includes a second fixing plate 610 mounted at the top of the operating table 100. A liquid injection mold 620 is mounted on the outer wall of the second fixing plate 610, and a liquid injection pipe 630 is mounted on the outer wall of the liquid injection mold 620. A connecting component 640 is provided at the end of the second fixing plate 610 away from the liquid injection mold 620. A cooling groove 650 is formed on the inner wall of the liquid injection mold 620. The connecting component 640 includes a positioning water pipe 641 disposed on the inner wall of the second fixing plate 610. An opening 642 is formed on the outer wall of the positioning water pipe 641. A cooling water pipe 644 is provided on the outer wall of the positioning water pipe 641. A water pump 643 is mounted on the outer wall of the positioning water pipe 641. A connecting water pipe 340 is provided on the outer wall of the water pump 643.

The injection pipe 630 and the cooling tank 650 are not at the same level, and the injection pipe 630 passes through the injection mold 620. The connecting water pipe 340 connects the water pump 643 and the cooling water tank 310. The connecting water pipe 340 is made of PVC material, allowing the water pump 643 to directly draw out the cooling water stored in the cooling water tank 310 through the connecting water pipe 340. After drawing out the water, it can be used to cool the mold after molding through the cooling water pipe 644. When the equipment cools the mold, the water flowing out through the cooling water pipe 644 can be directly discharged through the pipe opening 642, thus allowing the mold and the injection mold 620 to be directly separated during demolding. ,

[0025] Working principle: When the equipment is needed, the drive pump 520 can directly drive the positioning rod 540 to slide within the first fixed plate 510 and control the movable plate 550 to slide into the injection mold 620. After the movable plate 550 moves to the appropriate position, the worker directly introduces the molding material into the injection pipe 630, and the set-top box shell begins to be shaped. The connecting water pipe 340 can directly draw out the cooling water stored in the cooling water tank 310, and after drawing it out, the mold after the molding is completed can be cooled through the cooling water pipe 644.
