Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of thermoplastic fluoroelastomer plastic liner shaped device, and its volume is little, with low cost, and the bushing pipe of moulding can not produce the defects such as bubble.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of thermoplastic fluoroelastomer plastic liner shaped device, comprise the mould for moulding bushing pipe body, described mould comprises patrix, middle mould, counterdie and the plug for moulding bushing pipe endoporus; Described patrix, middle mould, counterdie coordinate the forming cavity surrounding for moulding bushing pipe profile; Between described patrix and middle mould, middle mould and counterdie, be connected by flange; Described patrix comprises sleeve, and described sleeve one end is connected with flange; Described plug extends into forming cavity by sleeve; Also comprise the platen of an annular; The outside diameter of described platen equals sleeve diameter of bore; The diameter of bore of platen equals diameter of mandrel; Platen can slide up and down along plug; This shaped device also comprises a device for exerting that is used to platen to exert pressure.
Improve as one, described device for exerting is hydraulic press; Also comprise a forcing pipe, described forcing pipe is placed on plug, and its upper surface contacts with hydraulic press press member, and its lower surface contacts with platen upper surface.Utilize hydraulic press as device for exerting, its equipment interoperability is strong, and cost is low, operates also very convenient.And its pressure is huge, can guarantee that molten state high viscosity fluoroplastics fluid fills forming cavity, discharges the air in fluid, cooling under pressure, make fluoroplastics become a closely knit liner entirety, thereby avoid staying the defect such as space, bubble.
Improve as one, on described middle mould lateral wall, be provided with some reinforcements, avoid the lower mould deformation fracture of pressure.
Improve as one, on described middle mould sidewall, have through hole, also comprise a measurement electrode hole forming rod that extends into through hole; On described through hole and dip hatch moulding stick, be provided with the step cooperatively interacting; On middle mould lateral wall, be positioned at through hole both sides and be provided with fixed bar, fixed bar top has axial inner bolt hole; Also comprise a pressing plate, described pressing plate contacts with dip hatch moulding stick upper surface; On pressing plate, be provided with the screw corresponding with the inner bolt hole of fixed bar, and rely on bolt and fixed bar to fix.For one-shot forming bushing pipe, reprocess without moulding later, increase operation.
Usefulness of the present utility model is: have the shaped device of said structure, simple in structure, volume is little, and equipment interoperability is high.And the bushing pipe of its moulding can not produce the defects such as bubble, interior sky.
