Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of die head one preferred embodiment on extruder of the present invention;
Fig. 2 is the sectional view of the die head on extruder of Fig. 1;
Fig. 3 is the pictorial diagram of the die head on extruder of Fig. 1.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A die head on extruder, comprises ground floor 1 and the second layer 2, and described ground floor 1 is connected setting with the second layer about 2.Described ground floor 1 is provided with the shape of the mouth as one speaks 3 of " e " type design, the shape of the mouth as one speaks 3 of described " e " type design is arranged through described ground floor.Be provided with passage 4 in the described second layer 2, the shape of the mouth as one speaks 3 that described passage 4 designs with described " e " type communicates.
The shape of the shape of the mouth as one speaks 3 of described " e " type design is axisymmetric
type, is namely provided with a polygonal breach on the basis of circle.The diameter of described circle is 22 ± 0.1mm, described polygon breach is zhou duicheng tuxing and has 5 limits, Zhong Liangtiao limit, described 5 limits is parallel and described polygonal interior angle is 2 right angles, 2 obtuse angles and 1 acute angle, the distance on two limits of described polygonal parallel is 5 ± 0.1mm, the R angle≤0.1mm of the described shape of the mouth as one speaks.
The outer shape of described ground floor 1 is cylindrical, and the basal diameter of described ground floor 1 is 90 ± 0.1mm, and the height of described ground floor 1 is 7 ± 0.1mm.The outer shape of the described second layer 2 is cylindrical, and the basal diameter of the described second layer 2 is 100 ± 0.1mm, and the height of the described second layer 2 is 40 ± 0.1mm.The cross section of described passage 4 is trapezoidal, and the upper bottom side length of described trapezoid cross section is 22 ± 0.1mm, and the length of side of going to the bottom is 84 ± 0.1mm.The material of described die head is S50C.The smooth surface of described die head and impulse-free robustness.
The invention has the beneficial effects as follows:
One, the product that the described die head on extruder of application is produced is the cylindrical shape tube banks of multilayer rank, top oral area circle internal diameter is minimum, dull and stereotyped vertical compression mould is easy to form bubble or be vented bad, therefore by preforming material glue embryo die head die design for " e " shape be one of the most effective way, preformed fetus produce time, because material " e shape " has opening, with circular or columnar phase ratio, more be conducive to matched moulds exhaust, product does not have the phenomenons such as exhaust is bad, bubble of choking with resentment and occurs;
Two, this die design reduces mould improvement cost and transformation cycle greatly, adopting the design of " e " shape to replace the circular or column compression mod of inertial thinking cannot the drawback of deaeration, simultaneously grind material and mandrel contact frictional force little, substantially improve product and be adsorbed on possibility on mould, because core tip first thrusts preformed fetus, but " e shape " material opening is larger, rub less, so compare without adhesion with circular or columnar phase during product stripping, greatly reduce product delivery difficulty, improve production efficiency;
Three, because " e shape " preforming material uses, making product be vented bad, bubble incidence drops within 1% by 85%, greatly improve product quality, promoted the volume production of this product, the possibility that product mucous membrane occurs have dropped more than 95%, greatly reduces staff labor intensity and improves per unit area yield production capacity, production capacity is promoted to 175pcs from 75pcs per hour, personnel's modulo operation is simply easy, shortens the delivery cycle greatly, decreases the possibility that employee scalds.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
