Abstract
The utility model discloses a multi-channel co-extrusion windowsill board extrusion mold. The extrusion mold comprises an open mold, a conflux plate, a core rod supporting plate, a shunt cone supporting plate, a first transition plate, a second transition plate, a third transition plate, a fourth transition plate, a mold body, a shunt cone and a core rod, wherein a shut channel and a main channel are arranged on the conflux plate; a plurality of large shunt feed ports and a plurality of small shunt discharge ports are formed in the shunt channel on the conflux plate; a plurality of supporting ribs I are arranged in inner holes of the first transition plate; a plurality of supporting ribs II are arranged in inner holes of the second transition plate; a wedge-shaped supporting rib I is arranged in an inner hole of the third transition plate; and a wedge-shaped supporting rib II is arranged in an inner hole of the fourth transition plate. The multi-channel co-extrusion windowsill board extrusion mold has the advantages of high strength, even flow of plastic fluid, high production efficiency and long service life; and pasted materials do not exist and the quality of produced products is good.
Description
Technical field
The utility model relates to mould of plastics, particularly a kind of multithread road coextrusion window platen extrusion die.
Background technology
Existing windowsill extrusion die all adopts sprue and single runner to process, though this single runner processing is comparatively easy, processing cost is lower, but there are the following problems: the one, and runner is bigger, be prone to the inhomogeneous phenomenon of feed, and the plastic liquid in the mould usually produces decomposition because of overheated; The 2nd, because runner is bigger, the intensity of mould is lower, and this certainly will influence the service life of mould, thereby increases the use cost of mould.
The utility model content
The purpose of this utility model just provides that a kind of intensity height, plastic liquid flow evenly, the multithread road coextrusion window platen extrusion die of thickener, the good product quality that processes, production efficiency height, long service life not.
For achieving the above object, the utility model comprises a mouthful mould, cylinder manifold, the plug supporting plate, divide the flow cone supporting plate, rebound one, rebound two, rebound three, rebound four, die body, divide flow cone and plug, described cylinder manifold is provided with runner and sprue, the runner of described cylinder manifold is provided with several bigger shunting charging apertures and several less shunting discharging openings, be provided with several brace rods I in the endoporus of described rebound one, be provided with several brace rods II in the endoporus of described rebound two, be provided with wedge shape brace rod I in the endoporus of described rebound three, be provided with wedge shape brace rod II in the endoporus of described rebound four, described die body is provided with main charging aperture, flow cone was loaded on the branch flow cone supporting plate by feet in described minute, described plug is loaded on the plug supporting plate by feet, described mouthful of mould, cylinder manifold, the plug supporting plate, divide the flow cone supporting plate to be connected successively by screw three with rebound one, described rebound one is connected by screw one successively with rebound two, described rebound two is connected by screw four successively with rebound three, and described rebound three is crossed screw two with the rebound four-way and is connected successively; The cross section of described brace rod I and brace rod II is two ends point, shape broad in the middle; The cross section of described wedge shape brace rod I is left small and right large triangular shaped; The cross section of described wedge shape brace rod II is left large and right small triangular shaped; Described wedge shape brace rod I and wedge shape brace rod II shape symmetry and corresponding one by one.
The utility model is owing to the runner at cylinder manifold is provided with several bigger shunting charging apertures and several less shunting discharging openings, in the endoporus of rebound one, be provided with several brace rods I, in the endoporus of rebound two, be provided with several brace rods II, in the endoporus of rebound three, be provided with wedge shape brace rod I, in the endoporus of rebound four, be provided with wedge shape brace rod II, the cross section of brace rod I and brace rod II is the two ends point, shape broad in the middle, the cross section of wedge shape brace rod I is left small and right large triangular shaped, the cross section of wedge shape brace rod II is left large and right small triangular shaped, wedge shape brace rod I and wedge shape brace rod II shape symmetry and corresponding one by one, after adopting such structure, can improve the intensity of mould on the one hand greatly, thereby improve the service life of mould, can improve the flowability of plastic liquid on the other hand, avoid the generation of thickener phenomenon, and can guarantee that plastic liquid flows evenly, improves the quality of product.The utility model intensity height, plastic liquid flow evenly, thickener not, the good product quality that processes, production efficiency height, long service life.
