Summary of the invention
For the technical deficiency of above-mentioned existence, the object of this invention is to provide a kind of setscrew nut and dismantling device thereof of double-wall pipe mould outer wall core, this setscrew nut can firmly be pushed against outer wall core on outer wall core spacer shell, guarantee outer wall raw material is not revealed, and then ensures the unimpeded of gas passage.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of setscrew nut of double-wall pipe mould outer wall core, described double-wall pipe mould comprises the inwall mould that is used to form inner layer wall, be used to form the outer wall mold of outer wall, described outer wall mold comprises the outer wall core spacer shell at middle part, outer wall core, on the periphery wall of described outer wall core spacer shell, there is an outer step surface, the end axis of described outer wall core is to being pushed against on described outer step surface, on the internal perisporium of described outer wall core, there is an interior step surface, described inwall mould comprises the inwall mouth mould spacer shell at middle part, this setscrew nut is connected on described inwall mouth mould spacer shell by internal thread, and the corresponding end of described setscrew nut is pushed against on described interior step surface, described outer wall core axial location is between described outer wall core spacer shell and described setscrew nut, the end away from described outer wall core spacer shell of described setscrew nut has multiple recesses.
Preferably, on described setscrew nut, offer multiple passages that extend vertically.
A kind of dismantling device of setscrew nut of arbitrary double-wall pipe mould outer wall core described above, this dismantling device is circular, extends axially on protuberance that multiple recesses of being provided with on multiple and described setscrew nut match, another axial end portion and be provided with the operating portion of being convenient to it to rotate in its one axial end.
Preferably, described operating portion is the multiple grooves that extend vertically that circumferentially distribute.
Beneficial effect of the present invention is: the setscrew nut by the design is by outer wall core and the outer wall core spacer shell location that offsets, ensure that in production process, outer wall raw material is not revealed, and then prevent that gas passage from stopping up, and for this setscrew nut of easy disassembly, need the design's dismantling device, utilize its can be fast, easily setscrew nut is carried out to dismounting, be suitable for promoting the use of.
