The specific embodiment
Below in conjunction with accompanying drawing, specify embodiments of the invention.
As shown in Figure 1, the embodiment of the mould of the even extruding spinning of a kind of fluorine material, this mould includes a die ontology 1, and this die ontology 1 inner formed inner chamber.The T type die that die ontology 1 adopts new No. three steel to process in the present embodiment; The structure of die ontology 1 is made as flat cube; Its long and high length is close, and wide length is much smaller than long and high, and promptly this die ontology 1 is made as its two relative structures that side, end face and bottom surface are narrower.End face at die ontology 1 is provided with supply port 4, and material gets in the die ontology 1 inner formed inner chamber through this supply port 4.
Like Fig. 2 and combine shown in Figure 1; A plane that parallels with die ontology 1 front and back; Die ontology 1 is divided into the die assembly 1a and the die assembly 1b of shape symmetry; This plane is vertical with side, end face and the bottom surface of die ontology 1, and tangent on the center line of its each face with this side, end face and bottom surface, makes the identical and symmetrical configuration of structure size of die assembly 1a with the die assembly 1b be used to be combined into die ontology 1.
Bottom at die assembly 1a and die assembly 1b; Its two relative each other bottom faying faces are respectively bottom faying face 2a and bottom faying face 2b; This bottom faying face 2a and faying face 2b place, bottom be depression setting accordingly respectively; Make when die assembly 1a and die assembly 1b are combined into die ontology 1, between bottom faying face 2a and bottom faying face 2b, form an outside opening that is communicated with die ontology 1 inner chamber in bottom surface that makes die ontology 1.
Between bottom faying face 2a and bottom faying face 2b, be folded with a flat board 5, this flat board 5 adopts new No. three steel to process.The appearance of the length of this flat board 5 and die ontology 1 etc.; The opening that forms between dull and stereotyped 5 wide and bottom faying face 2a and the bottom faying face 2b is complementary; When die assembly 1a and die assembly 1b were relatively combined, dull and stereotyped 5 were embedded between bottom faying face 2a and the bottom faying face 2b in the formed opening dull and stereotyped 5 two sides just; Be plane 5a with plane 5b; Fit with bottom faying face 2a and bottom faying face 2b respectively, plane 5a and bottom faying face 2a fit tightly, and plane 5b and bottom faying face 2b fit tightly.
As shown in Figure 3, on the bottom faying face 2a of die assembly 1a and die assembly 1b and the bottom faying face 2b respectively at interval cut have some as groove 3a, the groove 3b of spinning with nozzle.This some groove 3a, groove 3b laterally arrange each other.Through these a plurality of grooves, the material in die ontology 1 inner chamber flows out from the bottom of die ontology 1, and forms many spinning s simultaneously.
As Fig. 4 and combine shown in Figure 1, dull and stereotyped 5 plane 5a with plane 5b on also respectively cut some groove 6a and groove 6b are arranged.The mutual parallel interval setting of groove 6a on the 5a of plane, the shape size of the groove 3a on this several grooves 6a and the bottom faying face 2a is suitable, and the position of this several groove 6a also with bottom faying face 2a on the corresponding one by one setting in position of groove 3a.Equally; The mutual parallel interval setting of groove 6b on the 5b of plane; The shape size of groove 3b on this several grooves 6b and the bottom faying face 2b is suitable, and the position of this several groove 6b also with bottom faying face 2b on the corresponding one by one setting in position of groove 3b.Make and to combine as die assembly 1a and die assembly 1b, and in dull and stereotyped 5 openings that are arranged between bottom faying face 2a and the bottom faying face 2b time, groove 6a makes up the formation through nozzle hole with corresponding one by one settings of groove 3a is also mutual; And groove 6b and also corresponding one by one setting of groove 3b and combination each other form through nozzle hole.This through nozzle hole is made up of two semicircular grooves, makes its nozzle that forms complete circle, makes from through nozzle hole, to flow out more smooth and easyly when spinning, increases work efficiency.
For die ontology 1 can flow down and form the spinning s that a plurality of and mutual adhesion does not disturb simultaneously; This through nozzle hole laterally arranges each other; And bottom view by die ontology among Fig. 41; These several through nozzle hole are provided with abreast at interval, and the spacing between while two adjacent nozzle through holes is set to greater than 5 millimeters.The diameter of each through nozzle hole is set to greater than 20 millimeters, and the scope of length is arranged on 50 millimeters to 100 millimeters.
As shown in Figure 1, the shoulder of die assembly 1a and both sides, die assembly 1b end face place is provided with some turnbuckle screw v, is used for the top of die assembly 1a and die assembly 1b is fixed together.And on bottom faying face 2a and bottom faying face 2b; Its two ends are provided with some turnbuckle screw v separately; Simultaneously corresponding two ends dull and stereotyped 5 are provided with some screws, through these some turnbuckle screw v the bottom of die assembly 1a and die assembly 1b are fixed together.
At the mould of the even extruding spinning of fluorine material of present embodiment in running; Pour into the fluorine material of fusion in the inner chamber of its die ontology 1 through supply port 4; In order the ground that makes mould of the present invention can not be more smoothly to flow out the fluorine material and to form the spinning s of fluorine material from the through nozzle hole of die ontology 1 bottom; The fluorine material of this fusion need satisfy its melt index MFR greater than 25g/10min, promptly per 10 minutes 25 grams.In order to make the fluorine material in the die ontology 1 keep above-mentioned requirements, the operating temperature range that the mould of the even extruding spinning of this fluorine material need keep is arranged on 300 ℃ to 350 ℃.
Equally, since polyethylene, polypropylene; Polyvinylchloride, the PVDF resin, the character and the fluorine material of synthetic resin materials such as PFA resin and ETFE are similar; The mould of the even extruding spinning of fluorine material of the present invention also can be to above-mentioned polyethylene, polypropylene, polyvinylchloride; The PVDF resin, synthetic resin such as PFA resin and ETFE carry out spinning.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
