[0015] 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.

[0016] like Figures 1-7 As shown in the figure, this embodiment provides an example of a quick-release display front frame injection mold.

[0017] A quick-release injection mold for a display front frame includes a fixed mold base plate 1 and a movable mold base plate 2. The top of the fixed mold base plate 1 is provided with a lower mold 3, and the bottom of the movable mold base plate 2 is provided with an upper mold 4. Both the fixed mold base plate 1 and the movable mold base plate 2 are provided with quick-release structures 5. The quick-release structure 5 includes a support frame 6 symmetrically fixedly installed on the surfaces of the fixed mold base plate 1 and the movable mold base plate 2. A locking rod 7 is movably installed on the support frame 6. Multiple first springs 8 are provided between the support frame 6 and the locking rod 7. Multiple locking blocks 9 are fixedly installed on the surfaces of the lower mold 3 and the upper mold 4.

[0018] By setting up the quick-release structure 5, the connection structure between the lower mold 3 and the upper mold 4 and the fixed mold base plate 1 and the moving mold base plate 2 is optimized. After the lower mold 3 and the upper mold 4 are installed on the fixed mold base plate 1 and the moving mold base plate 2 respectively, multiple locking blocks 9 on both sides of the lower mold 3 and the upper mold 4 are inserted into the support frames 6 set on both sides of the fixed mold base plate 1 and the moving mold base plate 2. Then, the locking rod 7 is pushed into the slot opened on one side of the locking block 9 and fastened by multiple first springs 8. The connection is fixed by the locking of multiple locking rods 7 and locking blocks 9. When disassembling and replacing the lower mold 3 and the upper mold 4, it is not necessary to disassemble a large number of bolts and connecting parts. The disassembly can be completed by directly pulling the locking rod 7, which makes the operation simpler and avoids affecting the production efficiency of the front frame of the display.

[0019] In this embodiment, as Figure 1As shown, a limiting frame 10 is fixedly installed on one side of the support frame 6. A limiting groove 11 is opened on the limiting frame 10. A fixing block 12 is fixedly installed on one end of the clamping rod 7. Two first grooves 13 are opened on one side of the fixing block 12. A clamping plate 14 is slidably installed inside the first groove 13. Multiple second springs 15 are provided between the first groove 13 and the clamping plate 14. The diameter of the other end of the clamping rod 7 is equal to the inner diameter of the groove on one side of the clamping block 9. One side of the clamping plate 14 is set as a bevel structure. Fixing plates 16 are fixedly installed on both ends of the first spring 8. Multiple first bolts 17 are provided on the fixing plate 16. Multiple threaded grooves are opened on both the support frame 6 and the clamping rod 7.

[0020] Through the arrangement of the limiting frame 10, limiting groove 11, fixing block 12, first groove 13, clamping plate 14, and second spring 15, the fixed mold base plate 1 and the lower mold 3, as well as the moving mold base plate 2 and the upper mold 4, are fixedly connected by multiple sets of clamping rods 7 and clamping blocks 9. During disassembly, multiple clamping rods 7 need to be pulled and disassembled one by one. After disassembling the clamping rod 7, the fixing block 12 on one side is inserted into the limiting groove 11 on the limiting frame 10. Then, the two clamping plates 14 on one side of the fixing block 12 extend outward from the first groove 13 and abut against the outside of the limiting frame 10 under the extension and push of multiple second springs 15. In this way, the clamping of the limiting frame 10 and multiple clamping plates 14 can lock the disassembled clamping rod. The rod 7 is fixed in a limiting position to prevent the disassembled rod 7 from resetting when other rods 7 are disassembled. By setting the diameter of one end of the rod 7 to be equal to the inner diameter of the groove on one side of the block 9, the connection between the rod 7 and the block 9 is made tighter and more stable. At the same time, when one side of the plate 14 is set as a bevel structure, the fixing block 12 can squeeze and shrink the two plates 14 when it is inserted into the limiting groove 11, thereby reducing resistance and facilitating the connection between the fixing block 12 and the limiting frame 10. With the setting of the fixing plate 16 and the first bolt 17, the first spring 8 is installed on the support frame 6 and the rod 7 by the connection of the first bolt 17 and the threaded groove, which improves the firmness of the installation of the first spring 8.

[0021] In this embodiment, as Figure 1 As shown, a plurality of guide pillars 18 penetrating the lower mold 3 are fixedly installed on the top surface of the fixed mold base plate 1. The surface of the guide pillars 18 is provided with a nitrided layer. A second groove 19 is opened on the top of the guide pillars 18. A third spring 20 is fixedly installed inside the second groove 19. A damping plate 21 is fixedly installed at one end of the third spring 20. Cooling pipes 22 are provided on both the lower mold 3 and the upper mold 4. Shut-off valves 23 are provided on both ends of the cooling pipes 22 extending to the outside. The cooling pipes 22 and the shut-off valves 23 are fixedly connected by a plurality of flanges and a second bolt.

[0022] The guide post 18 allows for the positioning of the connection between the lower mold 3 and the upper mold 4. The nitrided layer reduces friction and wear, extending service life. The second groove 19, the third spring 20, and the damping plate 21 further reduce the impact force when the lower mold 3 and the upper mold 4 come into contact, providing protection for them. The cooling pipe 22 facilitates internal cooling of the lower mold 3 and the upper mold 4, reducing internal stress and preventing deformation and cracking of the display front frame. The shut-off valve 23 allows for easy control of the coolant flow within the cooling pipe 22, enabling the supply of coolant to be shut off during maintenance or replacement of the lower mold 3 and the upper mold 4. It also allows for adjustment of the coolant flow rate according to actual production needs.

[0023] In this embodiment, as Figures 1-7 As shown, the working process of a quick-release display front frame injection mold provided in this embodiment is as follows: After the lower mold 3 and the upper mold 4 are respectively installed on the fixed mold base plate 1 and the moving mold base plate 2, the multiple locking blocks 9 on both sides of the lower mold 3 and the upper mold 4 are inserted into the support frames 6 set on both sides of the fixed mold base plate 1 and the moving mold base plate 2. Then, the locking rod 7 is pushed into the locking groove opened on one side of the locking block 9 and fastened by multiple first springs 8 to achieve a fixed connection between the fixed mold base plate 1 and the lower mold 3, and between the moving mold base plate 2 and the upper mold 4. During disassembly, pull each of the levers 7 one by one so that one end of it disengages from the slot on one side of the lever 9, and insert the fixing block 12 on one side of the lever 7 into the limiting slot 11. The lever 7 is limited and fixed by the engagement of the limiting frame 10 and multiple locking plates 14 until the multiple levers 7 and the locking blocks 9 are completely separated, and the disassembly is completed.
