Abstract
The invention discloses a combined extrusion-molding mold used in wire cable processing. The mold is mainly composed of a mold core, a mold sleeve seat, a mold nozzle, and a cover plate. A cylindrical stepped concave platform hole formed by contraction and transition from a tail-end second tapered hole to an axis is arranged in the mold sleeve seat. A cylindrical hole formed by contraction and transition from a tail-end third tapered hole to the axis is arranged in the mold nozzle. An extrusion molding channel is uniformly formed between the inner wall of the second tapered hole on the mold sleeve seat and the outer wall of the mold core arranged therein. The mold nozzle and the cover plate are arranged in the mold sleeve seat. The tail end of the third tapered hole of the mold nozzle and the head end of the second tapered hole are smoothly connected into a complete extrusion-molding channel. The mold has the advantages that: with the mold nozzle manufactured by using polytetrafluoroethylene, surface smoothness of extruded plastic can be improved, and cable appearance can be improved. A same set of mold sleeve seat and cover plate can be shared by molds with different specifications, such that a large amount of material and processing time can be saved, and cost can be substantially reduced. When the specification needs changing, only the mold core and the mold nozzle are changed. The assembly and disassembly are convenient, and production efficiency is high.
