Description

Technical Field

[0001] This utility model relates to the technical field of in-mold injection molding devices for mobile phone mid-frames, and in particular to an in-mold injection molding device for a composite mobile phone mid-frame reinforced with titanium alloy and carbon fiber. Background Technology

[0002] The modern mobile phone market pursues a balance between ultra-thin and lightweight design and high strength, with particularly fierce competition in the high-end market. Titanium alloy and carbon fiber reinforced composite materials, with their excellent strength-to-weight ratio and unique texture, have become the ideal choice for high-end mid-frames. The application of in-mold injection molding devices is to achieve efficient and precise integrated molding of these two high-performance materials and plastic structural parts. This technology can significantly improve the degree of production automation, ensure the precision of complex structures, effectively reduce labor costs, meet the ultimate requirements of product design and the needs of large-scale production, and support the direction of sustainable manufacturing.

[0003] Currently, after each injection molding process, the mold of the mobile phone frame requires manual cleaning to prevent residual foreign matter from affecting the next injection molding. Manual cleaning takes a long time, which greatly slows down the processing speed. After the first piece is produced, the product usually needs to be cut and inspected to check for material problems. However, the injection molding device does not have a cutting structure, so the product needs to be sent to the cutting equipment, which is very time-consuming and greatly reduces the continuity of production.

The electro-hydraulic device 5 is a device that converts electrical energy into hydraulic energy and then outputs mechanical work through hydraulic actuators. It consists of an electric motor, a hydraulic pump, an oil tank, and a control valve. It can extend the distance of the output end and has a self-locking function. This is existing technology and will not be described in detail. An upper mold 6 is fixedly installed on the output end of the electro-hydraulic device 5, and four supports are fixedly connected to the upper side of the upper mold 6. The four sliding rods 27 are slidably connected to the top plate 3. The four sliding rods 27 can ensure that the upper mold 6 will not shift during the movement. An injection box 7 is fixedly installed on the upper side of the top plate 3. A telescopic hose 8 is fixedly connected between the injection box 7 and the upper mold 6. The injection box 7 can melt the raw material so that the melted raw material can be transported into the upper mold 6 through the telescopic hose 8. This is existing technology and will not be described in detail. The telescopic hose 8 has the effects of high temperature resistance and telescopic length. This is existing technology and will not be described in detail. A cleaning structure is installed on the support rod 2, and a cutting structure is also installed on the injection table 1.

[0022] The cleaning structure includes a control motor 9 fixedly mounted on the upper side of the injection molding table 1. A threaded rod 10 is rotatably connected between two support rods 2. A rubber ring connects the threaded rod 10 to the two support rods 2 to prevent the threaded rod 10 from rotating. The output end of the control motor 9 is connected to the threaded rod 10 via a pulley assembly 11, which consists of two pulleys and a belt. A sliding plate 12 is threadedly connected to the outer side of the threaded rod 10. Two fixed rods 26 are fixedly connected to the side walls of the two support rods 2. The fixed rods 26 restrict the movement of the sliding plate 12 under the action of the threaded rod 10. Both fixed rods 26 are slidably connected to the sliding plate 12. The side walls of the sliding plate 12 are rotatably connected... A rotating shaft 13 is connected, and a spur gear 14 is fixedly sleeved on the outside of the rotating shaft 13. A rack 15 is fixedly connected between two support rods 2. The two support rods 2 are the same as the two support rods 2 of the rotatably connected threaded rod 10. The spur gear 14 meshes with the rack 15. Multiple rotating rods 16 are rotatably connected to the side wall of the slide plate 12. The rotating shaft 13 is connected to one of the rotating rods 16 through a pulley assembly 2 17. The pulley assembly 2 17 also consists of two pulleys and a belt, which can transmit the power of the rotating shaft 13 to the rotating rod 16 adjacent to the rotating shaft 13. A spur gear 2 18 is fixedly sleeved on the outside of each of the multiple rotating rods 16, and adjacent spur gears 2 18 mesh with each other. Cleaning brushes 19 are fixedly connected to both ends of each of the multiple rotating rods 16.

[0023] The cutting structure includes an extension plate 20 fixedly connected to the side wall of the injection molding table 1. Two fixed plates 21 are fixedly connected to the side wall of the extension plate 20. A rotating shaft 22 is rotatably connected between the two fixed plates 21. The rotating shaft 22 is connected to the threaded rod 10 through a pulley assembly 3 23. The pulley assembly 3 23 also consists of two pulleys and a belt, which transmits the power of the threaded rod 10 to the rotating shaft 22. A cutting blade 24 is fixedly installed on the outside of the rotating shaft 22. Two baffles 25 are fixedly connected to the upper side of the extension plate 20. The baffles 25 can prevent debris from flying onto the surface of the injection molding table 1 during cutting and affecting the injection molding.

[0024] In this invention, firstly, the operator moves the upper mold 6 downwards using the electro-hydraulic device 5 until it fits against the lower mold 4. The raw material is then fed in through the injection box 7 and the telescopic hose 8 for injection molding. After the product is removed from the injection mold, the control motor 9 is activated, causing it to drive the threaded rod 10 to rotate via the pulley assembly 11. The rotation of the threaded rod 10 allows the slide plate 12 to slide outside the two fixed rods 26. During the sliding of the slide plate 12, the rotating shaft 13 rotates via the spur gear 14 and the rack 15. The rotating shaft 13 rotates via the pulley assembly 17. The rotating rod 10 drives the adjacent rotating rod 16 to rotate. The multiple rotating rods 16 drive the cleaning brushes 19 at both ends to rotate through the adjacent spur gears 18. The cleaning brushes 19 can also rotate on their own as they move with the slide plate 12, resulting in better cleaning effect. The rotation of the threaded rod 10 also drives the rotating shaft 22 to rotate through the pulley assembly 23. The rotating shaft 22 drives the cutting blade 24 to rotate, which can cut the freshly produced sample, greatly saving the time for sending it for inspection. Problems can be solved in time, saving a lot of time and increasing the continuity of production.
