Abstract
The utility model discloses a kind of extrusion die improving tube surfaces fineness; comprise core, mouth mould, mouth modular ring, core ring; mouth modular ring is fixed on a mouthful mould flow path wall exit; core ring is fixed on core flow path wall exit, and mouth modular ring and core ring define annular melt outlet runner at runner exit place.The utility model solves tube surfaces in tubing production process and occurs drawing the defects such as trace, concave point, pit, reducing the phenomenon of hanging mould, reduce the frequency of cleaning mould, solve conventional coatings mode simultaneously and hold caducous problem, it is simple and reasonable, extruding pipe material smooth surface.
Description
Technical field
The utility model relates to the tubular article formation mould in a kind of tubular object extruding equipment, is specifically related to a kind of extrusion die improving tube surfaces fineness.
Background technology
In prior art, in the production process of tube forming, easily occur that tube surfaces has the defect of drawing the surface smoothnesses such as trace, concave point, pit; When equipment is started shooting for a long time, easily occur hanging mould phenomenon, need the problem of frequent cleaning mould; Coating easily comes off, the problem such as must frequently to do over again.
Summary of the invention
Task of the present utility model is to provide a kind of extrusion die improving tube surfaces fineness, and when it can solve tube forming in prior art, surface occurs drawing the defects such as trace, concave point, pit; Reduce due to the extension mould phenomenon occurred of starting shooting for a long time, thus reduce the frequency needing to clear up mould; Solve coating easily to come off, need the problem of frequently doing over again.
The utility model is realized by following technical proposals:
A kind of extrusion die improving tube surfaces fineness; comprise core, mouth mould, mouth modular ring, core ring; mouth modular ring is fixed on a mouthful mould runner exit place, and core ring is fixed on core runner exit place, and mouth modular ring and core ring define annular melt discharging opening at runner exit place.
Above-mentioned mouth modular ring and core ring are fixed on corresponding mould by mouth mold pressing ring and core pressure ring respectively; and compressed by contact of incline plane face between ring and pressure ring; very moment modular ring and core ring are due to when there is mild wear in start for a long time; suitable keeper mold pressing ring and core pressure ring; give convergent force in mouthful modular ring and core ring, thus reach the object of regulating ring size.
Above-mentioned mouth modular ring, core ring are that Teflon material or its surface uniform are coated with one deck Teflon; Teflon has the feature of extremely low, high temperature resistant, the antiacid alkali resistant of coefficient of friction, anti-various organic solvent; be dissolved in all solvents hardly; so can be used as to lubricate; improve tube surfaces fineness; reduce and hang mould phenomenon, solve coating and easily to come off problem.
Above-mentioned mouth mold pressing ring and core pressure ring and reservedly between mouth mould and core regulate gap;
Above-mentioned mouth mold pressing ring and core pressure ring are bolted on corresponding mould by hoop is equally distributed.
Relative to prior art, the beneficial effects of the utility model are:
The utility model achieves the object improving tube surfaces fineness, solve tube surfaces in existing production process to occur drawing the defects such as trace, concave point, pit, reducing the phenomenon of hanging mould, reduce the frequency of cleaning mould, solve conventional coatings mode simultaneously and hold caducous problem, it is simple and reasonable, extruding pipe material smooth surface.
Accompanying drawing explanation
Fig. 1 is a kind of cross-sectional view improving the extrusion die of tube surfaces fineness of the utility model;
Fig. 2 is the enlarged diagram of I part in Fig. 1.
Detailed description of the invention
Composition graphs 1, Fig. 2, describe detailed description of the invention of the present utility model in detail, but be not limited in any way claim.
A kind of extrusion die improving tube surfaces fineness; comprise core 1, mouth mould 2, mouth modular ring 3, core ring 5; core 1 is through mouth mould 2 inner chamber; gap between core 1 outer surface and mouth mould 2 inwall forms an annular melt discharging runner 7; mouth modular ring 3 is arranged on mouthful mould flow path wall 72 exit; core ring 5 is arranged on core flow path wall 71 exit, there is uniform gap between mouth modular ring 3 and core ring 5, and mouth modular ring 3 and core ring 5 define annular discharging opening 8 in runner 7 exit.
Described a kind of extrusion die improving tube surfaces fineness, also comprise a mouthful mold pressing ring 4, core pressure ring 6, described mouth modular ring 3 outer wall is the conical surface, an end face external diameter near discharging opening 8 is less than other end external diameter, core ring 5 inwall is the conical surface, core ring 5 is greater than other end internal diameter near an end face internal diameter of discharging opening 8, the inwall of mouth mold pressing ring 4 is the conical surface, the outer wall of core pressure ring 6 is the conical surface, the conical surface of mouthful mold pressing ring 4 and the cone match of mouth modular ring 3 closely adapt mouth modular ring 3 to press and are fixed on mouthful mould 2, the conical surface of core pressure ring 6 and the cone match of core ring 5 closely adapt core ring 5 to press and are fixed on core 1.
Above-mentioned mouth modular ring 3 and core ring 5 are fixed on corresponding mould by mouth mold pressing ring 4 and core pressure ring 6 respectively; and compressed by contact of incline plane face between ring and pressure ring; very moment modular ring 3 and core ring 5 are due to when there is mild wear in start for a long time; suitable keeper mold pressing ring 4 and core pressure ring 6; give convergent force in mouthful modular ring 3 and core ring 5, thus reach the object of regulating ring size.
Above-mentioned mouth modular ring 3, core ring 5 are coated with one deck Teflon for Teflon material or its surface uniform, Teflon has the feature of extremely low, high temperature resistant, the antiacid alkali resistant of coefficient of friction, anti-various organic solvent, be dissolved in all solvents hardly, so can be used as to lubricate, improve tube surfaces fineness, reduce and hang mould phenomenon, solve coating and easily to come off problem;
Above-mentioned mouth mold pressing ring 4 and core pressure ring 6 and reservedly between mouth mould 2 and core 1 regulate gap 12;
Above-mentioned mouth mold pressing ring 4 and core pressure ring 6 are bolted on corresponding mould by hoop is equally distributed.
