Description

Technical Field

[0001] This utility model relates to the field of high-temperature melting device technology, and in particular to a high-temperature melting device for injection molding raw materials for television casings. Background Technology

[0002] In the modern home appliance manufacturing industry, televisions, as essential electronic products for every household, have seen continuous growth in production scale. The television casing, as a crucial component of the television set, not only protects the internal electronic components but also significantly impacts the product's appearance design and overall quality. Injection molding is currently the mainstream method for large-scale television casing production, and one of the core steps in this process is the high-temperature melting treatment of the injection molding raw materials.

[0003] A high-temperature melting device for TV casing injection molding raw materials, with application number CN202420573625.6, includes a processing table, a transparent protective door, a protective top plate, a stable conveying component, a quantitative feeding tank, a melt plasticizing injection component, and a TV casing pressing and shaping component. The processing table is surrounded by a transparent protective door; a protective top plate is installed on top of the transparent protective door; a stable conveying component for stable guiding movement is installed at the upper end of the processing table; a quantitative feeding tank for mixing and adding the TV casing injection molding raw material is installed at the upper end of the protective top plate; a melt plasticizing injection component for efficient melt plasticizing and pressurized injection of the raw material is installed at the upper end of the stable conveying component; and a TV casing pressing and shaping component for use in conjunction with the melt plasticizing injection component is installed at the upper end of the processing table.

[0004] The aforementioned patent document describes a method to drive a molten plastic injection assembly to move laterally in a stable direction, enabling the molten plastic injection assembly to efficiently and stably melt and plasticize the raw material for TV casing injection molding and to inject it under pressure, thus achieving a stable pressing and shaping effect. However, since its quantitative feeding tank is fixed at the top of the processing table, when injecting solid raw materials into the molten plastic injection assembly, a flexible hose can be used to facilitate movement during injection. Because the raw material is solid, blockage may occur in the hose, preventing the device from processing and potentially damaging the machine. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing quantitative feeding tanks are fixed on the top of the processing table. When injecting solid raw materials into the melting and plasticizing injection assembly, only flexible hoses can be used for easy movement during injection. Since the raw materials are solid, blockage may occur in the hoses, preventing the device from processing and potentially damaging the machine. Therefore, this invention proposes a high-temperature melting device for TV shell injection molding raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-temperature melting device for injection molding raw materials of television casing includes an outer shell. A groove is formed at the top of the inner wall of the outer shell. A drive motor is provided on the outer wall of the outer shell. A lead screw is fixedly connected to the output end of the drive motor. The lead screw is connected to a quantitative feeding tank through a transmission structure. A direct conveying pipe is provided at the bottom end of the quantitative feeding tank. A melting and plasticizing injection assembly is connected through the bottom end of the direct conveying pipe.

[0008] Preferably, the transmission structure includes a moving block, a slide rod, an outer wall protrusion, a moving roller, and a through opening. The moving block is slidably connected to the inner wall of the slide groove, and the slide rod is fixedly connected to the inner wall of the slide groove.

[0009] Preferably, the outer wall protrusion is provided on the outer wall of the metering tank, the movable roller is fixedly connected to the bottom end of the outer wall protrusion, and the wheel of the movable roller abuts against the top end of the outer shell.

[0010] Preferably, the through-hole is located at the top of the outer shell, and the through-hole communicates with the chute. The direct conveying pipe slides through the moving block and is slidably connected to the inner wall of the through-hole.

[0011] Preferably, the inner wall of the chute has a limiting groove, a connecting plate is fixedly connected to the left side of the melt plasticizing injection assembly, and limiting blocks are provided on the outer walls of both sides of the connecting plate. The limiting blocks are slidably connected to the limiting groove, and the connecting plate is slidably connected to the lead screw and the slide rod respectively.

[0012] Preferably, a device processing table is fixedly connected to the bottom end of the outer shell, an anti-scalding soft pad is provided at the center of the top of the device processing table, and a transparent protective door is provided at the opening of the outer shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, this utility model allows the metering tank to move along with the melting and plasticizing injection assembly via a direct feed pipe, outer wall protrusions, moving rollers, and limiting grooves. Replacing the potentially bendable hose with a direct feed pipe makes the input of solid raw materials smoother, greatly reducing the occurrence of blockages and thus preventing the device from being unable to process materials or the machine from being damaged.

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3 A high-temperature melting device for injection molding raw materials of television casing includes an outer shell 1. A groove 2 is provided at the top of the inner wall of the outer shell 1. A drive motor 3 is provided on the outer wall of the outer shell 1. A lead screw 4 is fixedly connected to the output end of the drive motor 3. The lead screw 4 is connected to a quantitative feeding tank 5 through a transmission structure. A direct feeding pipe 6 is provided at the bottom end of the quantitative feeding tank 5. A melting and plasticizing injection assembly 7 is connected through the bottom end of the direct feeding pipe 6.

[0021] It should be noted that the drive motor 3, the quantitative feeding tank 5, and the melt plasticizing injection assembly 7 are existing technologies. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0022] Furthermore, the transmission structure includes a movable block 8, a slide rod 9, an outer wall protrusion 10, a movable roller 11, and a through opening 12. The movable block 8 is slidably connected to the inner wall of the slide groove 2, and the slide rod 9 is fixedly connected to the inner wall of the slide groove 2.

[0023] The transmission structure is achieved by starting the drive motor 3, which drives the lead screw 4 to rotate. The lead screw 4 drives the moving block 8 to move back and forth in the slide 2. When the moving block 8 moves, it drives the direct feed pipe 6 to move, and the direct feed pipe 6 drives the melt plasticizing injection assembly 7 to move.

[0024] Furthermore, an outer wall protrusion 10 is provided on the outer wall of the quantitative feeding tank 5, and a movable roller 11 is fixedly connected to the bottom end of the outer wall protrusion 10, with the wheel of the movable roller 11 abutting against the top end of the outer casing 1.

[0025] The outer wall protrusions 10 and the moving rollers 11 allow the metering tank 5 to move more smoothly as it follows the molten plasticizing injection assembly 7.

[0026] Furthermore, the through-hole 12 is located at the top of the outer shell 1, and the through-hole 12 is interconnected with the slide 2. The direct conveying pipe 6 slides and connects with the inner wall of the through-hole 12 while passing through the moving block 8.

[0027] The moving block 8 is fixedly connected to the outer wall of the direct conveying pipe 6, so that the drive motor 3 can move the quantitative feeding tank 5 while moving the melting and plasticizing injection component 7. Furthermore, after using the direct conveying pipe 6, solid raw materials are directly injected into the melting and plasticizing injection component 7, reducing bends and making the material conveying smoother.

[0028] Furthermore, a limiting groove 13 is provided on the inner wall of the chute 2, and a connecting plate 14 is fixedly connected to the left side of the melt plasticizing injection assembly 7. Limiting blocks are provided on both outer walls of the connecting plate 14, and the limiting blocks are slidably connected to the limiting groove 13. The connecting plate 14 is slidably connected to the lead screw 4 and the slide rod 9 respectively.

[0029] The upper part is the tail end stabilizing device of the molten plastic injection assembly 7, which allows the molten plastic injection assembly 7 to perform hydraulic extension and retraction, and also makes the molten plastic injection assembly 7 more stable when moving.

[0030] Furthermore, a device processing table 15 is fixedly connected to the bottom of the outer shell 1, and a heat-resistant soft pad 16 is provided at the center of the top of the device processing table 15. A transparent protective door 17 is provided at the opening of the outer shell 1.

[0031] The heat-resistant pad 16 is installed at the top of the processing table 15, which allows the shaped TV casing to fall directly onto the heat-resistant pad 16, protecting the TV casing from damage while preventing workers from directly contacting the hot TV casing that has just been processed, thus reducing the probability of workers being injured.

[0032] Working principle: When using this device, first start the drive motor 3. The drive motor 3 drives the lead screw 4 to rotate. The lead screw 4 drives the moving block 8 to move back and forth in the slide 2. When the moving block 8 moves, it drives the direct feed pipe 6 to move. The direct feed pipe 6 drives the melt plasticizing injection component 7 to move. At the same time, the direct feed pipe 6 can also drive the quantitative feeding tank 5 to move. Through the outer wall protrusion 10 and the moving roller 11, the quantitative feeding tank 5 can move more smoothly when following the melt plasticizing injection component 7. After using the direct feed pipe 6, the solid raw material is directly injected into the melt plasticizing injection component 7, reducing the number of bends and making the material conveying smoother. Finally, a heat-proof soft pad 16 is set on the top of the processing table 15 of the device. This allows the molded TV shell to fall directly onto the heat-proof soft pad 16, protecting the TV shell from damage while preventing workers from directly contacting the hot TV shell that has just been processed, reducing the probability of worker injury.

[0033] 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.
