Further, in this embodiment, two adjusting blocks 30 are provided, and four fixing blocks 20 are provided. Both the adjusting blocks 30 and the mounting blocks 10 are inclined relative to the wire harness injection molding mold 200, so that more wire harnesses 300 can be placed on the wire harness injection molding mold 200 of the same size for injection molding at the same time relative to the wire harness 300 placed directly opposite, thereby improving the efficiency of wire harness injection molding.

[0026] The adjusting block 30 is provided with a sliding groove 31, and the side walls of the two mounting blocks 10 are provided with sliding blocks 11 adapted to the sliding groove 31 and moving grooves 12 for the fixed block 20 to move, and the sliding block 11 is slidably arranged in the sliding groove 31. The side walls of the sliding block 11 are provided with a limiting block 111, and the sliding groove 31 is provided with a limiting groove 311 adapted to the limiting block 111, and the limiting block 111 is slidably arranged in the limiting groove 311. The moving groove 12 is parallel to the length direction of the wire harness injection mold 200.

[0027] The fixing block 20 is provided with a mounting groove 21 adapted to the wire harness 300, and the mounting groove 21 is provided with a limiting protrusion 211. When the wire harness 300 is placed in the mounting groove 21, the limiting protrusion 211 is located at the top of the wire harness 300 and abuts against the wire harness 300. Specifically, in this embodiment, the limiting protrusion 211 and the mounting groove 21 are integrally formed, and the sheathing layer of the wire harness 300 involved in the utility model has a certain elasticity. When the wire harness 300 is placed in the mounting groove 21, the wire harness 300 can be pressed into the mounting groove 21.

[0028] The side wall of the fixed block 20 is also provided with a moving block 22 adapted to the moving groove 12, and the moving block 22 is slidably arranged in the moving groove 12. The moving block 22 and the groove wall of the moving groove 12 are both provided with fixing holes 23. When the wire harness 300 is placed by injection molding, one end of the wire harness 300 is clamped in the installation groove 21, and the wire harness 300 is in a state of maximum stretched length.

[0029] The wire harness injection molding limiting device 100 also includes a fixing assembly 40, which includes a limiting screw 41 and a fixing screw 42, as well as a positioning block 43, a hand crank 44 and a positioning screw 45. The limiting screw 41 is rotatably arranged in the sliding groove 31, and the limiting screw 41 passes through the sliding block 11 and is threadedly connected to the sliding block 11. The positioning block 43 is fixedly connected to the adjustment block 30, and the positioning block 43 is provided with a plurality of positioning holes 1 431 adapted to the positioning screw 45, and the hand crank 44 is provided with a positioning hole 2 441 corresponding to the positioning hole 1 431, and the positioning screw 45 and the positioning hole 1 431 and the positioning hole 2 441 are all threadedly connected, and the hand crank 44 and the limiting screw 41 are coaxially fixed. Specifically, in this embodiment, two positioning blocks 43 are provided, and the two positioning blocks 43 correspond to the two adjustment blocks 30 respectively. There are a plurality of positioning holes 1 431, and the plurality of positioning holes 1 431 are distributed in a ring shape about the center of the positioning block 43. There is one positioning hole 441. When adjusting the position of the mounting block 10 relative to the wiring harness injection mold 200, the limit screw 41 is driven to rotate by the hand crank 44, thereby driving the sliding block 11 to slide along the sliding groove 31. When it is necessary to fix the position of the mounting block 10 relative to the wiring harness injection mold 200, the positioning screw 45 is sequentially passed through the positioning hole 441 and the positioning hole 431 at the corresponding position and tightened. The fixing screw 42 is adapted to the fixing hole 23. When fixing the position of the fixing block 20 relative to the mounting block 10, the fixing screw 42 passes through the fixing hole 23 at the corresponding position on the fixing block 20 and the fixing hole 23 at the corresponding position on the movable groove 12, and the fixing screw 42 and the fixing hole 23 are threadedly connected.

[0030] The working process of a wire harness injection limiting device 100 provided by the utility model is: move the mounting block 10, and after moving to a suitable position, fix the mounting block 10 on the adjusting block 30 by a positioning screw, so as to realize the overall adjustment of the fixed positions of multiple wire harnesses 300 that are injected simultaneously; when the length of one of the wire harnesses 300 is slightly different from that of the other wire harnesses 300, move the fixing block 20 so that the position of the fixing block 20 relative to the wire harness injection mold 200 changes; after moving to a suitable position, fix it with a fixing screw 42 to realize the adjustment of the limited position of one of the wire harnesses 300 on the mounting block 10. By changing the position of the fixing block 20 relative to the mounting block 10 and the position of the mounting block 10 relative to the wire harness injection mold 200, the position of the wire harness injection molding limit device 100 relative to the wire harness injection mold 200 can adapt to wire harnesses 300 of different lengths, and wire harnesses 300 of different lengths are all in a state of maximum stretching length during injection molding, so that the wire harness 300 is not easy to move during injection molding, thereby improving the practicality of the wire harness injection molding limit device 100.

[0031] Beneficial effect: When the wire harness 300 is placed by injection molding, the mounting block 10 is moved so that the position of the mounting block 10 relative to the wire harness injection mold 200 matches the length of the wire harness 300, and then the wire harness 300 is clamped in the mounting groove 21 on the mounting block 10, and the wire harness 300 is in a state of maximum stretched length. Thus, wire harnesses 300 of different lengths can be limited and fixed, so that the wire harness 300 is not easy to move during injection molding, thereby improving the practicality of the wire harness injection molding limiting device 100.
