Description

Guide pin bushing
Technical field
The utility model relates to mould, particularly relates to a kind of guide pin bushing in mould.
Background technology
Guide pin bushing is guide frame part conventional in mould, and traditional guide pin bushing is straight-tube shape, and guiding accuracy is poor, after a number of uses, easily reduces guiding accuracy because of wearing and tearing, does not meet the mould that required precision is higher.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides the higher and good guide pin bushing of wear resistance of a kind of guiding accuracy.
The utility model provides a kind of guide pin bushing, comprises guide sleeve body, and described guide sleeve body is provided with guide hole, and the madial wall of described guide hole is provided with bulge loop, and the protrusion direction of described bulge loop is along the radial direction of described guide hole to central protuberance.
As further improvement of the utility model, described bulge loop is arranged along the Axis Extension of described guide hole.
As further improvement of the utility model, described bulge loop is positioned at the shoulder of described guide hole.
As further improvement of the utility model, the edge of described bulge loop is provided with rounding.
As further improvement of the utility model, described bulge loop is arc-shaped convex.
As further improvement of the utility model, described bulge loop is single spherical surface hill.
As further improvement of the utility model, described bulge loop is two spherical surface hills.
As further improvement of the utility model, described bulge loop is that the face of cylinder is protruding.
As further improvement of the utility model, described guide pin bushing also comprises guide rod, and described guide rod is arranged in described guide hole, and described guide rod is located at accurate guide section, and described accurate guide section matches with described bulge loop.
The beneficial effects of the utility model are: by such scheme, by setting up bulge loop in guide hole, improve guiding accuracy, and, improve wear resistance by bulge loop, effectively can improve the service life of guide pin bushing.
