[0032] The embodiment provides a technical scheme:

[0033] Please refer to Figures 1-6As shown, the keyboard and mouse injection mold with a general interface comprises a base 1, the top of the base 1 is provided with a lower mold base 10, the top of the lower mold base 10 is provided with a keyboard punch 11, and the side of the keyboard punch 11 is provided with a plurality of mouse punches 12; the upper side of the base 1 is provided with a top base 2, the bottom of the top base 2 is provided with an upper mold base 20, the bottom of the upper mold base 20 is provided with a keyboard cavity 21, and the side of the keyboard cavity 21 is provided with a plurality of mouse cavities 22; the top of the upper mold base 20 is provided with a vertical gate 23; the gate 23 is provided with a standard gate sleeve 5; the bottom of the upper mold base 20 and the top of the lower mold base 10 are both provided with a horizontal half runner 3, the upper half runner 3 is communicated with the gate 23, the side of the half runner 3 is provided with a first branch 30 communicated with the keyboard cavity 21, and the other side of the half runner 3 is provided with a plurality of second branches 31 communicated with the mouse cavities 22; the top of the top base 2 is provided with a fixing assembly 4, the fixing assembly 4 comprises a frame 40 fixedly connected with the top base 2, two symmetrical clamping blocks 44 are arranged in the opening of the frame 40, and the opposite end faces of the two clamping blocks 44 are both provided with clamping grooves 440, and the clamping grooves 440 are clamped on the outer wall of the standard gate sleeve 5.

[0034] Further, a double-head screw rod 42 is rotatably arranged at one side of the opening of the frame 40, and the two ends of the double-head screw rod 42 pass through the two clamping blocks 44 and are threadedly connected with the clamping blocks 44. The thread groove of the two ends of the double-head screw rod 42 has opposite thread winding directions, and when the double-head screw rod 42 rotates, the two clamping blocks 44 can synchronously move relatively, so that the standard gate sleeve 5 can be conveniently disassembled and assembled;

[0035] In the embodiment, the front end of the double-head screw rod 42 passes through the frame 40 and is coaxially connected with an adjusting screw 420, and the outer wall of the adjusting screw 420 is provided with a plurality of anti-skid lines. The plurality of anti-skid lines arranged on the outer wall of the adjusting screw 420 increase the friction when the hand holds, so that the user can more easily rotate the adjusting screw 420, and meanwhile, the hand is prevented from slipping during the adjusting process, thereby facilitating the rotation of the double-head screw rod 42.

[0036] In the embodiment, the other side of the opening of the frame 40 is fixedly connected with a guide rod 41 through a bolt, and the guide rod 41 passes through the clamping block 44 and is slidably connected with the clamping block 44. The guide rod 41 plays a guiding role on the clamping block 44, and ensures the smoothness of the movement of the clamping block 44.

[0037] In the embodiment, the overall shape of the clamping groove 440 is arc-shaped, and the inner wall of the clamping groove 440 is provided with a plurality of anti-skid grooves 441. The arc-shaped design is beneficial to better clamping the standard gate sleeve 5, and the plurality of anti-skid grooves increase the friction between the standard gate sleeve 5 and the clamping groove 440, so that the object is prevented from slipping or loosening during the clamping process.

[0038] In the embodiment, the guide rails 400 are fixed to both sides of the opening of the frame 40, and the guide grooves 442 that are in sliding connection with the guide rails 400 are arranged at both ends of the clamping blocks 44. This design enables the clamping blocks 44 to move smoothly along the guide rails 400, while ensuring the linearity and accuracy of the movement of the clamping blocks 44.

[0039] In the embodiment, the ear plates 43 are fixed to the outer walls of the frame 40, and the ear plates 43 are fixedly connected to the top seat 2 by bolts. The ear plates 43 are fixedly connected to the top seat 2 by bolts, which has the advantages of simple and reliable connection mode and convenient installation and disassembly.

[0040] In the embodiment, the guide columns 13 are fixed to the top corners of the base 1, and the guide holes 24 that are in sliding connection with the guide columns 13 are arranged at the four corners of the top seat 2. The design of the guide columns 13 and the guide holes 24 enables the top seat 2 to be accurately positioned during movement, thereby improving the overall precision and stability of the device.

[0041] It should be noted that the cross-sectional shape of the half runner 3, the first sub-runner 30 and the second sub-runner 31 in the embodiment is semicircular. When the upper mold seat 20 and the lower mold seat 10 are closed, the upper and lower half runners 3, the first sub-runners 30 and the second sub-runners 31 are clamped against each other and form injection molding channels for the flow of molten plastic, thereby facilitating the injection of molten plastic into the keyboard cavity 21 and the mouse cavity 22.

[0042] In specific use, the user first inserts the standard sprue bush 5 into the sprue 23, then rotates the adjusting screw 420, which drives the double-headed screw rod 42 to rotate. At this time, the clamping blocks 44 on both sides move synchronously inward, and the clamping blocks 44 move closer to the standard sprue bush 5. When the clamping grooves 440 clamp the standard sprue bush 5, the standard sprue bush 5 is fixed, and the user stops rotating the adjusting screw 420. Next, the user connects the standard sprue bush 5 with the nozzle of the injection molding machine. The molten plastic enters the half runner 3 through the standard sprue bush 5, and then enters the first sub-runner 30 and the second sub-runner 31 on both sides through the half runner 3. Finally, the molten plastic enters the keyboard cavity 21 and the mouse cavity 22 on both sides. After the molten plastic cools and solidifies in the keyboard cavity 21 and the mouse cavity 22, the finished product is obtained.
