A kind of mould for being used to be molded the plastic tube with position limiting convex ring as described above, the mold core A portion uses steel
It is made, the mold core B portion is made of beryllium copper.
A kind of mould for being used to be molded the plastic tube with position limiting convex ring as described above, the die sleeve use steel
Into.
A kind of mould for being used to be molded the plastic tube with position limiting convex ring as described above, the die sleeve are equipped with through hole A,
The core rod is set in through hole A, and the mold core A portion is equipped with through hole B, and the mold core B portion is set in through hole B.
A kind of mould for being used to be molded the plastic tube with position limiting convex ring as described above, the mold core A portion is equipped with
The locating part that limitation mold core B portion is rotated relative to mold core A portion.
Compared with prior art, the invention has the advantages that：
1st, the present invention is used for using mold core A portion come the madial wall of moulding plastics pipe and adjacent position limiting convex ring using mold core B portion
The madial wall of moulding plastics pipe and remote position limiting convex ring, the thermal conductivity factor in mold core A portion are less than the thermal conductivity factor in mold core B portion so that
Plastic tube is located at the temperature in position limiting convex ring region and is higher than temperature of the plastic tube away from position limiting convex ring region after shaping, so that plastics
Intensity of the pipe positioned at position limiting convex ring region is higher than intensity of the plastic tube away from position limiting convex ring region, and then plastic tube is forced
When the demoulding, plastic tube can be made smoothly to demould, avoid forced stripper mechanism from damaging plastic tube, improve yield rate.
2nd, the die sleeve of this hair and mold core A portion, which can adopt, is made of a steel, and mold core B portion can be made of beryllium copper；Mold core B portion is adopted
It is made of beryllium copper, has both can guarantee that the intensity in mold core B portion, avoids mold core B portion during shaping from deforming, and the effect of heat dissipation can be improved
Rate, reduces cooling time, improves production efficiency.
