Summary of the invention
The utility model mainly provides a kind of low cost of manufacture, the PTFE isostatic pressed pipe shaping mould that Forming Quality is good, solves the manufacturing cost existed in prior art high, and cannot process the technical problem of the broad wall PTFE tube of small size etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of PTFE isostatic pressed pipe shaping mould, the external mold comprising tubulose and the core rod be coaxially plugged in external mold mesopore, external mold and core rod enclose the PTFE tube shaping mold cavity of tubulose jointly, and on the both-side opening end of PTFE tube shaping mold cavity, be respectively equipped with the plug of annular, described external mold is provided with several conductings in the through hole of PTFE tube shaping mold cavity, the external mold inner ring surface that through hole is corresponding is equipped with layers of elastomeric film, in layers of elastomeric film, PTFE powder is filled with in PTFE tube shaping mold cavity corresponding between plug and core rod, and keep being smoothly connected between core rod and plug and PTFE powder.During processing and forming, PTFE powder is dosed in PTFE tube shaping mold cavity, two openends up and down of PTFE tube shaping mold cavity are blocked again by plug, then mold integral is immersed in the water and pressurizes, press water applies pressure to layers of elastomeric film through the through hole on external mold, layers of elastomeric film all presses PTFE powder to make its isostatic compaction again, after hydrostatic profile, remove outward flange and the external mold of two openends, owing to keeping between the PTFE tube after core rod and plug and hydrostatic profile being smoothly connected, therefore core rod can take out smoothly, PTFE tube inner wall smooth and dimensional accuracy is high, Forming Quality is good, relatively existing PTFE tube is machining, low cost of manufacture, and can be used for the production of the broad wall PTFE tube of small size, save material cost.
As preferably, be provided with inner flange outside the external mold corresponding with described plug, to then outward flange on inner flange, outward flange is pressed on plug end face.Be pressed on two openends of PTFE tube shaping mold cavity by plug by inside and outside flange pressure, make PTFE powder be full of also compacting in die cavity, structure is simple, convenient disassembly.
As preferably, described layers of elastomeric film extends and is folded between the outer ring surface of external mold inner ring surface and plug.Layers of elastomeric film extends between the outer ring surface of external mold inner ring surface and plug, improves the sealing of PTFE tube shaping mold cavity, guarantees that PTFE tube is exerted pressure by layers of elastomeric film is stable in forming process, ensure that the quality of product.
Counterbore can be set in the external port at outward flange, as preferably, chamfering is provided with in the external port of described outward flange, O RunddichtringO is set with outside the core rod corresponding with chamfering, core rod outside outward flange is set with annular pressing plate, O RunddichtringO by annular pressing plate press seal on the mating surface of outward flange and core rod.Chamfer machining is simple, and O RunddichtringO guarantees PTFE tube shaping mold cavity positiver sealing, ensures the Forming Quality of PTFE tube.
Core rod can be the cylinder of real core, and as preferably, described core rod is tubular.Core rod adopts the circular tube structure of hollow, lightweight, is easy to carrying and dismounting.
As preferably, described layers of elastomeric film is rubber parts.Rubber parts cost is low, good springiness.
Therefore, PTFE isostatic pressed pipe shaping mould of the present utility model has following advantage: to be exerted pressure layers of elastomeric film by press water, PTFE powder is all pressed to make its isostatic compaction by layers of elastomeric film again, outward flange, external mold and core rod is removed successively after shaping, PTFE tube inner wall smooth and dimensional accuracy is high, Forming Quality is good, and relatively existing PTFE tube is machining, low cost of manufacture, and the processing and forming that can be used for the broad wall PTFE tube of small size; By arranging O RunddichtringO at PTFE tube shaping mold cavity port, guaranteeing that die cavity obtains positiver sealing, ensure that the Forming Quality of PTFE tube.
