Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing technology, and more specifically, to a mold for injection molding of wire harnesses and wire clips. Background Technology

[0002] Wire harness clips are key components used to fix and store wire harnesses, preventing them from being damaged by shaking and friction during equipment operation. They are widely used in automobiles, home appliances, industrial equipment and other fields.

[0003] Traditional wire harness and cable clip molding technology mainly relies on prefabrication and manual crimping processes: First, standard-sized individual cable clips are mass-produced from plastics (such as nylon, PBT, etc.) using an injection molding machine. Then, in the subsequent wire harness assembly process, operators manually or with the aid of simple jigs place the pre-cut wire harness into the clip slots. Finally, the locking structure of the cable clip is forcibly closed by physical means (such as manually squeezing with crimping pliers), thereby clamping and securing the wire harness.

[0004] However, this manual assembly method suffers from poor reliability and consistency in the connection between wire harnesses and wire clips. Due to the significant influence of the operator's skill level, this method results in large fluctuations in component assembly gaps and connection firmness, easily leading to poor compatibility between wire clips and wire harnesses. Furthermore, the manual assembly process can damage the insulation layer of the wire harness conductors, posing certain safety hazards. In terms of production efficiency, manual assembly relies on manual operation, is time-consuming per process, and is difficult to adapt to large-scale mass production. Utility Model Content
