Description
Technical field
The present invention relates to mould of plastics, particularly a kind of multiple flow passages coextrusion window platen extrusion die.
Background technology
Existing windowsill extrusion die all adopts sprue and single runner to process, although this single runner processing is comparatively easy, processing cost is lower, but there are the following problems: the one, and runner is larger, be prone to the inhomogeneous phenomenon of feed, and the plastic liquid in mould usually produces decomposition because of overheated; The 2nd, because runner is larger, the intensity of mould is lower, and this certainly will affect the mold use life-span, thereby increases the mold use cost.
Summary of the invention
Purpose of the present invention just is to provide that a kind of intensity is high, plastic liquid flows evenly, the multiple flow passages coextrusion window platen extrusion die of high, the long service life of thickener, the good product quality that processes, production efficiency not.
for achieving the above object, the present invention includes a mouthful mould, cylinder manifold, the plug supporting plate, the spreader supporting plate, rebound one, rebound two, rebound three, rebound four, die body, spreader and plug, described cylinder manifold is provided with runner and sprue, the runner of described cylinder manifold is provided with several larger 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, described spreader is loaded on the spreader supporting plate by feet, described plug is loaded on the plug supporting plate by feet, described mouthful of mould, cylinder manifold, the plug supporting plate, the spreader supporting plate is connected with rebound and is connected successively by screw three, described rebound one is connected with rebound and is connected successively by screw one, described rebound two is connected with rebound and is connected successively by screw four, and described rebound three is connected screw two and is connected successively with the rebound four-way, 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 is symmetrical and corresponding one by one with wedge shape brace rod II shape.
the present invention is owing to being provided with several larger shunting charging apertures and several less shunting discharging openings on the runner of cylinder manifold, be provided with several brace rods I in the endoporus of rebound one, be provided with several brace rods II in the endoporus of rebound two, be provided with wedge shape brace rod I in the endoporus of rebound three, be provided with wedge shape brace rod II in the endoporus of rebound four, 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 is symmetrical and corresponding one by one with wedge shape brace rod II shape, after adopting such structure, can greatly improve the intensity of mould on the one hand, thereby improve the mold use life-span, can improve the mobility of plastic liquid on the other hand, avoid the generation of thickener phenomenon, and can guarantee that plastic liquid flows evenly, improve the quality of product.Intensity of the present invention is high, and plastic liquid flows evenly, thickener not, and the good product quality that processes, production efficiency is high, long service life.
