Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold for a mobile phone middle plate with deburring function. Background Art

[0002] The mobile phone middle plate is an important accessory of the mobile phone, which is used to install the internal parts and the shell of the mobile phone. Therefore, the mobile phone middle plate will directly affect the cost of the mobile phone. Publication No.: CN218836045U discloses a semi-solid die-casting mold for a mobile phone middle plate, including a device table. A base is fixedly installed at the bottom of the device table. A stamping table is arranged at the top of the device table. A lower mold is arranged at the top of the stamping table. A stamping groove is formed inside the lower mold. A lifting structure that can move up and down is arranged inside the stamping groove. A top seat is arranged above the device table. A stamping cylinder is fixedly installed at the top of the top seat. A connecting plate is connected to the bottom of the top seat. An upper mold that cooperates with the lower mold is connected to the bottom of the connecting plate. By the action of the electric telescopic rod, the lifting table is driven to move upward, and then the mobile phone middle plate located inside the stamping groove is jacked up and lifted, facilitating demoulding between it and the stamping groove. However, in the process of using the above technology, after the mobile phone middle plate is formed, in order to make the border of the mobile phone middle plate smooth and flat, polishing is often required. Polishing increases the process and cost, and the production efficiency is low. Therefore, improvement is needed. Summary of the Utility Model

[0032] Embodiment 1

[0033] Please refer to Figures 1-4, the present utility model provides a technical solution: a die-casting mold for a mobile phone middle plate with deburring, including a workbench 1. A vertical rod 2 is fixedly installed on the surface of the workbench 1. The top of the vertical rod 2 is fixedly installed with a top plate 3. A die-casting cylinder 4 is fixedly installed on the top of the top plate 3. The output end of the die-casting cylinder 4 is fixedly installed with an upper mold 5. A guide rod 6 is fixedly installed on the surface of the upper mold 5. The guide rod 6 is slidably connected inside the top plate 3, which helps to ensure that the upper mold 5 can be accurately aligned during die-casting, avoid offset phenomena, thereby improving the accuracy of the die-casting mold and the quality of the finished product, reducing mold wear, and extending the service life of the mold. A lower mold 7 is fixedly installed on the surface of the workbench 1. A side plate 8 is fixedly installed inside the vertical rod 2. A clamping cylinder 9 is fixedly installed on the surface of the side plate 8. The output end of the clamping cylinder 9 is fixedly installed with a clamping plate 10. A telescopic rod 11 is fixedly installed between the clamping plate 10 and the side plate 8. The number of telescopic rods 11 is two groups, and the two groups of telescopic rods 11 are symmetrically distributed on the surface of the clamping plate 10. The symmetrical distribution of the telescopic rods 11 can provide stable support and more uniform pressure for the clamping plate 10, not only improving the stability of clamping, but also ensuring that the deburring process is more uniform and stable, reducing processing defects, and improving product quality. A slide rail 12 is fixedly installed inside the side plate 8. A deburring block 14 is slidably connected inside the slide rail 12. A fixed shell 15 is fixedly installed on the side of the deburring block 14. A roller 16 is rotatably connected inside the fixed shell 15. The roller 16 is in rolling connection with the slide rail 12. The design of the roller 16 reduces the friction of the deburring block 14 on the slide rail 12, making its movement smoother, improving work efficiency, and reducing the wear of mechanical components. At the same time, it also facilitates the deburring block 14 to perform deburring operations on the burrs of the mobile phone middle plate more smoothly. A chute 13 is opened on the surface of the slide rail 12. A slider 17 is fixedly installed on the surface of the deburring block 14. A dial 18 is fixedly installed on the surface of the slider 17. The slider 17 is slidably connected inside the chute 13, further enhancing the movement stability of the deburring block 14, making its movement along the slide rail 12 more accurate, and contributing to the accuracy of deburring.

[0034] Embodiment Two

[0035] Please refer to Figures 1-2, a support 19 is fixedly installed inside the workbench 1, a blanking cylinder 20 is fixedly installed on the surface of the support 19, a push plate 21 is fixedly installed at the output end of the blanking cylinder 20, a ejector pin 22 is fixedly installed on the surface of the push plate 21, and a round hole 23 is opened inside the lower die 7. After die casting is completed, the finished product can be ejected from the lower die 7 through the ejector pin 22, reducing the operation of manually taking out the product, improving the degree of automation, not only reducing the operation time, but also improving the production efficiency and safety. The ejector pin 22 is slidably connected inside the round hole 23, and the ejector pins 22 are evenly distributed on the surface of the push plate 21. The evenly distributed design of the ejector pins 22 ensures that the finished product is evenly stressed when ejected, preventing deformation or damage. Ensure that the product maintains a good shape during demoulding and improve the quality of the finished product.

[0036] Working principle: The lower die 7 is fixedly installed on the workbench 1 of the mold. The upper die 5 slides on the top plate 3 through the guide rod 6 and is driven by the die-casting cylinder 4. The output end of the die-casting cylinder 4 is fixedly connected to the upper die 5. After the cylinder is started, the upper die 5 is pushed down to close with the lower die 7 to complete the die casting of the mobile phone middle plate. The guide rod 6 ensures that the upper die 5 maintains precise alignment during the closing process, avoiding deviation and ensuring the quality of the formed part and the service life of the mold. When the mobile phone middle plate is formed, the clamping cylinder 9 drives the clamping plate 10 to move to fix the middle plate in the mold. The clamping plate 10 and the side plate 8 are supported by the telescopic rod 11. The telescopic rod 11 provides stable and symmetrical pressure to ensure that the middle plate does not shift during the deburring process. The deburring block 14 is fixed on the slide rail 12, and a chute 13 is provided inside the slide rail 12. The surface of the deburring block 14 is provided with a slider 17, and the slider 17 slides in the chute 13 to drive the deburring block 14 to move along the mold. The pick-up piece 18 installed on the surface of the deburring block 14 slides along the edge of the middle plate to precisely remove the excess burrs. The roller 16 is designed to achieve a rolling connection between the slide rail 12 and the deburring block 14, reducing the friction force and making the movement of the deburring block 14 smoother, effectively improving the deburring efficiency. After die casting is completed, the blanking cylinder 20 is started, and the push plate 21 drives the ejector pin 22 to eject the finished mobile phone middle plate from the round hole 23 of the lower die 7. The ejector pins 22 are evenly distributed on the surface of the push plate 21 to ensure that the finished product is evenly stressed when ejected, avoiding deformation or damage caused by uneven local stress. The design of the ejector pin 22 makes the automatic demoulding process more efficient, reduces manual operation, and improves the degree of automation and safety of production.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
