INJECTION MOLDING DEVICE FOR WRAPPING WIRES WITH THREE-COLOR SPIRAL INSULATION LAYERS AND THREE-COLOR WIRES

摘要

The present invention discloses an injection molding device for wrapping wires with three-color spiral insulation layers and three-color wires. The injection molding device comprises: a spinning block, a fixed mould, and a handpiece that are coaxially mounted. Each of the axes of these three components is provided with a center bore. The third plastic feeding pipe is arranged between the side wall of the handpiece and the center bore; a first plastic feeding pipe and a second plastic feeding pipe are arranged between the side wall of the fixed mould and the front end face thereof. This injection molding device is used to wrap wires up with three-color insulation layers. Three-color spiral wires are easy to identify and operate.
