Abstract
The invention discloses a double-chamber-coextruded extrusion-molding die of a plastic main sectional material. The double-chamber-coextruded extrusion-molding die comprises a coextrusion machine outlet device and two molding plates, wherein the two molding plates are provided with co-extruding flow channels; a material distributor is arranged at the molding die and connected with the coextrusion machine outlet device through a main co-extruding nozzle connecting device; and a material flow channel in the material distributor is divided from a main flow channel into two branched flow channels, and the two branched flow channels are respectively connected with the two molding plates provided with the co-extruding flow channels through branched co-extruding nozzle connecting devices. Due to the adoption of the technical scheme, the material is uniformly divided into two parts by the material distributor, the enough materials are provided for the material distributor by a main co-extruding nozzle flow path, and the material distributor and the flow channels of the molding plates are connected together by the branched co-extruding nozzle connecting devices; and the market requirement of the co-extruded plastic main sectional material is met, the productivity of an extruding device is adequately expressed, the production cost of the coextruded plastic main sectional material is lowered, and the production efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of extrusion molding molds for plastic profiles, and more specifically, the invention relates to a dual-cavity co-extrusion extrusion molding mold for plastic main profiles. Background technique [0002] The key technology of the plastic profile co-extrusion extrusion molding die is to cover the visible surface of the profile with a layer of co-extrusion layer material that is different from other non-visible surfaces. The co-extruded layer materials are bright in color and have good gloss, which improves the visual effect of the product and protects the product. [0003] The co-extrusion layer material is extruded through the co-extrusion extruder, and the co-extrusion flow channel of the mold is covered on the visible surface of the profile. [0004] The current plastic profile co-extrusion extrusion molds include single-cavity main profile co-extrusion dies, double-cavity auxiliary profile co-extrusion d...
