Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of low cost of manufacture, and intensity is high, the PFA mold pressing elbow forming die that Forming Quality is good.
Background technology
PFA is as a kind of macromolecular material of function admirable, it has good chemical stability, electrical insulating property, the extremely low coefficient of kinetic friction, nonflammable, resistance to chemical attack and higher mechanical strength, be widely used in all trades and professions, especially in anticorrosion equipment, as liner of anti-corrosion equipment, threeway, elbow etc., existing PFA elbow is generally by welding fabrication after the bending of PFA pipe, not only manufacturing cost is high, especially, while making the little wall thickness elbow of small size, often cannot ensure the quality of PFA elbow.
Summary of the invention
The utility model has mainly been to provide a kind of low cost of manufacture, and intensity is high, and the PFA mold pressing elbow forming die that Forming Quality is good has solved the PFA elbow manufacturing cost existing in prior art high, the technical problem that quality cannot ensure etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of PFA mold pressing elbow forming die, comprise metal bends, openend at metal bends is respectively equipped with inner flange, be respectively equipped with outward and the outward flange of inner flange interworking at the openend of described metal bends, in metal bends, be coaxially provided with core rod, the two ends of core rod stretch out and are inlaid on corresponding outward flange, outward flange, metal bends and core rod enclose PFA formable layer die cavity jointly, therein on an outward flange to being connected to sizing vat, the interworking briquetting that is being slidably connected in sizing vat, and sizing vat corresponding to briquetting below is connected with PFA formable layer die cavity by several material guide holes.By core rod is coaxially set in metal bends, and interworking is installed outward flange on the inner flange at metal bends two ends, make outward flange, metal bends and core rod enclose PFA formable layer die cavity jointly, and outward flange docking sizing vat therein, and sizing vat is connected with PFA formable layer die cavity, when PFA mold pressing bend forming, granular PFA powder is poured in PFA formable layer die cavity from sizing vat, and by the briquetting compacting PFA powder in sizing vat, again by mold integral heat temperature raising, PFA powder melting in die cavity, again briquetting is exerted pressure, briquetting further sinks along sizing vat bucket wall, the PFA of melting material in compacting die cavity, after compression molding, open and remove after core rod in original metal bends liner one deck PFA layer uniformly after outward flange, with respect to traditional structure, simple in structure, low cost of manufacture, the metal bends of outer lining has improved bulk strength and the quality of product.
As preferably, described sizing vat is the circular staving being coaxial docking on outward flange, in the sizing vat lower port corresponding with outward flange, is provided with counterbore, is provided with boss on outward flange, and boss interworking is inlaid in counterbore.Outward flange is fixed in the counterbore of sizing vat lower port by boss setting-in, and fixed form is simple, has both ensured the axiality of sizing vat and outward flange, thereby has guaranteed to enter the PFA powder amount uniformity of PFA formable layer die cavity.
As preferably, described material guide hole is axially disposed within on outward flange, and material guide hole is along the circumferential direction uniform on corresponding outward flange between core rod and sizing vat inwall.When material guide hole is along the circumferential direction uniform on corresponding outward flange between core rod and sizing vat inwall, guarantees to enter the PFA powder amount uniformity of PFA formable layer die cavity, thereby ensured the PFA layer consistent in density of liner.
As preferably, be provided with locating hole at the outward flange medial surface corresponding with described sizing vat, core rod interworking is inlaid in locating hole, is provided with lower locating hole at another outward flange medial surface relative with sizing vat, and core rod interworking is inlaid in lower locating hole.Core rod is inlaid in upper and lower locating hole, and fixed form is simple and reliable, thereby has ensured the axiality of core rod, makes the PFA layer thickness uniformity of liner.
As preferably, described PFA formable layer die cavity horizontally outward extends to form annular PFA layer flange chamber at the outer surface of inner flange.PFA layer flange chamber makes the PFA layer of liner be lining in the surface of two ends inner flange outward, has improved the antiseptic property of PFA mold pressing elbow docking end face.
Therefore, PFA mold pressing elbow forming die of the present utility model has following advantage: PFA and, is lining in formation PFA mold pressing elbow in metal bends, with respect to traditional welding fabrication structure, low cost of manufacture, the metal bends of outer lining has improved bulk strength and the quality of product.
