Problems solved by technology
[0002] Existing extrusion dies for window sills are all processed with a main channel and a single runner. Although this single runner is easier to process and has a lower processing cost, it has the following problems: First, the runner is relatively large and prone to The phenomenon of uneven feeding, and the plastic fluid in the mold is often decomposed due to overheating; second, due to the large runner, the strength of the mold is low, which will inevitably affect the service life of the mold, thereby increasing the use cost of the mold

The invention discloses a multi-runner co-extruded window board extruding die. The die comprises an aperture die, a confluence board, a core rod bracket board, a sprue spreader bracket board, a first transition board, a second transition board, a third transition board, a fourth transition board, a die body, a sprue spreader and a core rod, wherein sub-runners and a main runner are arranged on the confluence board, the sub-runners on the confluence board are provided with a plurality of big shunt feeding ports and a plurality of small shunt discharging ports, a plurality of supporting ribs I are arranged in inner holes of the first transition board, a plurality of supporting ribs II are arranged in inner holes of the second transition board, a wedge-shaped supporting rib I is arranged in an inner hole of the third transition board, and a wedge-shaped supporting rib II is arranged in an inner hole of the fourth transition board. The die disclosed by the invention is high in strength, uniform in plastic fluid flowing, free from thickener, good in processed product quality, high in production efficiency and long in service life.
Description
technical field [0001] The invention relates to a plastic mold, in particular to a multi-channel co-extrusion window sill extrusion mold. Background technique [0002] Existing extrusion dies for window sills all adopt main channel and single runner for processing. Although this single runner is easier to process and has lower processing cost, it has the following problems: first, the runner is relatively large and prone to The phenomenon of uneven feeding, and the plastic fluid in the mold is often decomposed due to overheating; second, due to the large runner, the strength of the mold is low, which will inevitably affect the service life of the mold, thereby increasing the use cost of the mold. Contents of the invention [0003] The purpose of the present invention is to provide a multi-channel co-extrusion window sill extrusion die with high strength, uniform flow of plastic fluid, no paste, good quality of processed products, high production efficiency and long service...
