Connection-peg.
At present, conventional mould is divided into two classes, and one kind is the nonadjustable fixing mould of external diameter；One kind is the mould of outer radius variable
Tool, the nonadjustable fixing mould of external diameter are stripped relatively difficult after shaping, and interior wall frictions of the Cheng Zhonghui to tubing, shadow are dragged in the demoulding
The quality of speaking pipe material.And the mould of outer radius variable is typically now all and the mould of this undergauge mode by the way of undergauge
Due to being all overall shrinkage, the mould part of shaping bell and spigot joint and the mould part for supporting body portion thus be accordingly used in
All radial contractions, and there is error in the body of the tubing of specification of the same race, cause the external diameter of mould to change greatly so that finally it is molded
Bell and spigot joint there is also larger error.
