[0001] This utility model belongs to the field of mold processing technology, and in particular relates to a wire harness series integrated injection mold structure. Background Technology
[0002] For wire harness overmolding products, the market demand for this product is increasing. However, in the past, the molds were usually used for separate overmolding, and when there were many points, 4-5 sets of molds were needed. This has the following drawbacks: 1) Separate overmolding has a long production cycle and wastes manpower; 2) Separate overmolding results in more waste material during injection molding, which wastes materials; 3) Separate overmolding requires more sets of molds, which increases development costs; 4) Separate overmolding increases the overall defect rate of the product.

[0005] Preferably, the adjusting wire harness fixture includes a movable plate with a U-shaped groove on the upper surface of the movable plate, in which the wire harness is clamped. The movable plate has a sliding groove in the middle in the front-back direction, and a limiting bolt corresponding to the sliding groove is installed on the worktable. The movable plate can drive the wire harness to be adjusted in the front-back direction on the worktable.
[0006] Preferably, the adjustment mechanism includes a slider, and a limiting groove is provided on the worktable. The slider slides back and forth in the limiting groove, and the hot runner plate is clamped on the slider. In turn, the slider drives the hot runner plate and the injection mold to adjust in the front and back direction as a whole. The slider is provided with locking bolts corresponding to the worktable.
[0007] Preferably, the workbench is equipped with a fixing component corresponding to the lower end of the injection mold.
[0008] Preferably, the hot runner plate is provided with a material injection pipe.
[0009] This utility model has the following advantages over traditional equipment: 1) It has a clever structure that can complete the wrapping of nodes with different spacing on the wire harness in one go, enabling sustainable production without frequent mold changes, and effectively reducing labor, development, and production material costs; 2) The adjustment mechanism and fixing components can effectively ensure product accuracy, achieve sustainable production, reduce product defects caused during the production process, and improve product yield; 3) It effectively shortens production time, reduces costs and increases efficiency, and achieves sustainable production.

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0014] Depend on Figures 1 to 2 A wire harness series integrated injection mold structure is provided, including a worktable 1, a hot runner plate 2 on the worktable 1, a hot runner channel inside the hot runner plate 2, multiple injection molds 3 horizontally placed on the worktable 1, the injection molds 3 being connected to the hot runner channel, a wire harness 4 on the worktable 1, the wire harness 4 passing through the multiple injection molds 3 in sequence, an adjusting wire harness fixture located between two adjacent injection molds 3 on the worktable 1, the adjacent adjusting wire harness fixtures being distributed in the front-back direction, and an adjusting mechanism for controlling the front-back movement of the hot runner plate 2 on the worktable 1.
[0015] The adjustment fixture for the wire harness includes a movable plate 5. The upper surface of the movable plate 5 is provided with a U-shaped groove, and the wire harness 4 is clamped in the U-shaped groove. The movable plate 5 is provided with a sliding through groove 6 in the middle of the front and back direction. The worktable 1 is equipped with a limiting bolt 12 corresponding to the sliding through groove 6. The movable plate 5 can drive the wire harness 4 to adjust in the front and back direction on the worktable 1.
[0016] The adjustment mechanism includes a slider 7. The worktable 1 is provided with a limiting groove 11. The slider 7 slides back and forth in the limiting groove 11. The hot runner plate 2 is clamped on the slider 7. Then the slider 7 drives the hot runner plate 2 and the injection mold 3 to adjust the overall back and forth direction. The slider 7 is provided with a locking bolt 8 corresponding to the worktable 1.
[0017] The workbench 1 is equipped with a fixing component 9 that corresponds to the lower end of the injection mold 3.
[0018] To facilitate material injection, the hot runner plate 2 is provided with an injection pipe 10.
[0019] In use, the wire harness 4 is first placed on the workbench 1. The wire harness 4 is arranged in an orderly manner through various adjusting wire harness fixtures. The specifications of each adjusting wire harness fixture can be different according to actual needs to meet the requirements of different spacing nodes on the wire harness 4 for gluing. The moving plate 5 slides back and forth on the workbench 1, and the U-shaped groove drives the wire harness 4 to slide back and forth. Then, the moving plate 5 is fixed to the workbench 1 by the limiting bolt 12, thereby realizing the adjustment of the length of the wire harness 4. Then, the hot runner plate 2 and multiple injection molds 3 are clamped on the workbench 1 from top to bottom. The wire harness 4 passes through the injection mold 3. The structure of each injection mold 3 can also be different. The hot runner plate 2 is clamped on the slider 7, and the slider 7 moves through the limiting groove. The slide 11 in the front-back direction adjusts the position of the hot runner plate 2 and multiple injection molds 3 on the worktable 1. After adjustment, tighten the locking bolt 8, fix the slider 7 on the worktable 1, and install the fixing component 9 on the worktable 1. The fixing component 9 clamps and fixes the lower end of the injection mold 3. Finally, the hot melt adhesive is injected into the hot runner plate 2 through the injection pipe 10 and transported to each injection mold 3 through the hot flow channel in the hot runner plate 2. Each injection mold 3 performs encapsulation treatment on different positions of the wire harness 4. The multi-point molding mechanism has high working efficiency, reduces production costs, realizes the serial injection of the wire harness 4, and has a high yield rate. The outer layer of the wire harness 4 is injection molded to form a plastic layer, and then the mold is opened and the material is unloaded.
