Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The high-density polyethylene HDPE board die cladding co-extrusion structure device shown in figures 1, 2 and 3 comprises a die body 1, a co-extrusion material feeding hole 2 is arranged at the central position of the upper surface of the die body 1, a T-shaped main runner 3 with the top communicated with the co-extrusion material feeding hole 2 is arranged on the front surface of the die body 1, 8 longitudinal sub-runners 4 are arranged at the upper end of the main runner 3 on the front surface of the die body 1, first storage bins 5 which are parallel to each other are arranged on the back surface of the die body 1, second feed bin 6 and four mutually independent third feed bins 7, 1 back of mould body is located 5 tops of first feed bin and sets up 8 minutes silo 8 that are linked together with first feed bin 5, and the inside width of minute silo 8 is from last down grow gradually, and 1 inside being located of mould body indulges and has put subchannel 4 and correspond the position and all seted up branch material hole 9 between the silo 8, indulges and puts subchannel 4, branch material hole 9 and branch silo 8 and be the shallow runner mode in the middle of the both ends is dark.

Further, in order to match with material guiding, the third bunker 7 is an inclined bunker with a low front part and a high rear part, further, in order to prevent series flow, a first flow blocking table 10 is arranged between the first bunker 5 and the second bunker 6, a second flow blocking table 11 is arranged between the second bunker 6 and four mutually independent third bunkers 7, further, in order to match with processing production, the number of the distribution holes 9 in the die body 1 is 8, further, in order to keep the same flow rate at different positions, the inner aperture of the distribution hole 9 in the die body 1 is gradually increased from two sides, the inner aperture of the distribution hole 9 in the die body 1 is increased from the middle to the outer inner aperture by multiple of 2, further, in order to facilitate material guiding, the inner width of the longitudinal branch runner 4 is the same as the inner aperture of the distribution hole 9 at the corresponding position, further, in order to match with production processing, the length of the die body 1 is 640mm, the height of mould body 1 is 280mm, mould body 1 is inside to be seted up length and is 472mm, highly be 84.8mm put opening 12 in, the utility model discloses a high density polyethylene HDPE panel die cladding is crowded constructional device altogether will crowd the material flow in mould altogether from crowded material feed port 2 altogether, rethread sprue 3 is indulged the branch runner 4 reposition of redundant personnel of putting on both sides from left and right sides, sprue 3, indulge the mode that shallow both sides progressively deepened in the middle of putting sprue 4 and branch material hole 9 adoption, utilize the fine characteristic of high density polyethylene material mobility, make crowded material reposition of redundant personnel more even altogether, crowd the material through the feed bin manifold many times again altogether, improve the effect of converging, at last from third feed bin 7 cladding to the goods surface, make the very even cladding of crowded material altogether to the goods surface, promote cladding effect and product quality greatly.

As shown in fig. 1, co-extruded materials flow into a die from a co-extruded material feeding hole 2 and are divided to the left and right sides through a main runner 3, and the main runner 3 adopts a mode that the middle part is shallow and the two sides are gradually deepened; then enters the material distributing hole 9 through the longitudinally arranged sub-runners 4; the longitudinally-arranged branch runners 4 and the material distributing holes 9 also adopt a mode that the middle part is shallow and the two sides are gradually deepened and enlarged. Because the fluidity of the high-density polyethylene material is good, if the distance between two sides is longest, the co-extruded material flows away from the middle runner if the runners are as deep as the same, and the runners on two sides almost have no material, so that the co-extruded material is not uniform; this is done in order to achieve a uniform splitting of the coextrusion. As shown in fig. 2, the co-extruded material enters a material distribution groove 8 through a material distribution hole 9, the material distribution groove 8 also adopts a flow channel mode that two sides are deep and the middle is shallow, the co-extruded material is converged for the first time through a first storage bin 5, and the converging effect is improved by a first flow blocking platform; the co-extruded materials enter a second storage bin 6 to be converged for the second time, and the second flow blocking table improves the converging effect again; and finally, the co-extruded material enters a third storage bin 7 to be coated on the surface of the product. Such a structure allows for a very uniform coating of the final co-extrusion onto the surface of the article by laminar flow splitting.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
