Abstract

The utility model discloses a kind of guide-post of die-set, comprise for cylindrical guide pillar main body, guide pillar main body two ends are provided with chamfering, described guide pillar main body offers toroidal cavity, is equipped with snap ring in groove, and described guide pillar main body offers thermal vias vertically.The utility model installation and removal are convenient, can greatly reduce the amount of labour, thus raise labour efficiency, meanwhile, decrease the wearing and tearing to guide-post of die-set itself, extend its service life.And dispel the heat in time when can ensure that guide pillar works.

Description

Guide-post of die-set

Technical field

The utility model belongs to technical field of mold, particularly relates to a kind of guide-post of die-set.

Background technology

The guide-post of die-set used in current industry is generally while with the pin assembly of broadside hat, when this guide-post of die-set is taken out from mould, artificial one end never with cap is needed to be pounded out, therefore the shortcoming of this guide pillar shows as: one, the amount of labour is large, all bring unnecessary production consumption to thus workman and enterprise, also cause the reduction of productivity ratio; Its two, large to the loss of guide-post of die-set itself, the service life of guide-post of die-set is shortened.Therefore, prior art needs further to be improved.

In addition, at home in punching production, use common punch press more, it is less that high velocity ram machine uses, because common punch press speed is slower, the needs of production development can not be met, the use of high velocity ram machine has become following development trend, but mould is when high velocity ram machine works, guide pillar easily produces severe friction, produce amount of heat simultaneously, make guide pillar temperature too high, in addition existing common die is solid guide pillar, radiating effect own is bad, when dispelling the heat not in time, guide post surface can produce fusing sintering phenomenon, produce stress deformation, the positioning precision of guide pillar is reduced, punching production is caused and has a strong impact on.

And, existing mold guide pillar many employings cylinder single structure, because any part will cause whole guide pillar to use after damaging in single cylinder, and the guide pillar of whole stressed time without any buffering leeway, it is greatly stressed when this structure makes guide pillar use, be easy to abrasion deformation, the life-span is short.

Utility model content

The purpose of this utility model is just to provide a kind of guide-post of die-set, can solve above-mentioned the deficiencies in the prior art part completely.

The purpose of this utility model is realized by following technical proposals:

A kind of guide-post of die-set, comprise for cylindrical guide pillar main body, guide pillar main body two ends are provided with chamfering, it is characterized in that: described guide pillar main body offers toroidal cavity, is equipped with snap ring in groove, and described guide pillar main body offers thermal vias vertically.

As a kind of preferred structure of the present utility model, described guide pillar main body is connected and composed by elastic component mutually by multi-segment structure.

As a kind of preferred structure of the present utility model, described snap ring is notched annulus.

Compared with prior art, the beneficial effects of the utility model are:

1. structure is simple, reasonable in design, and installation and removal are convenient, can greatly reduce the amount of labour, thus raise labour efficiency, meanwhile, decrease the wearing and tearing to guide-post of die-set itself, extend its service life.

2. dispel the heat in time when can ensure that guide pillar works.

3. because guide pillar main body is made up of multistage, and flexible connection between every section, so can impulsive force be reduced in the course of work, greatly improve service life, reduce operation cost of enterprises.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with specific embodiments and the drawings, the utility model is further described.

As shown in Figure 1, a kind of guide-post of die-set, comprise for cylindrical guide pillar main body 1, guide pillar main body 1 two ends are provided with chamfering 2, described guide pillar main body 1 offers toroidal cavity 3, is equipped with snap ring 4 in groove 3, and this snap ring 4 is notched annulus.Described guide pillar main body 1 offers thermal vias 5 vertically.

In order to improve the shock resistance of guide pillar entirety, described guide pillar main body 1 is connected and composed by elastic component 6 mutually by two-stage structure.

When mounted, can insert in the pin-and-hole of mould by any one end of guide pillar main body 1, by this guide-post of die-set press-in die, snap ring 4 opens to be fixed guide-post of die-set in a mold.When dismantling, without the need to turnover mould, directly knock one end of guide-post of die-set, snap ring 4 tightens up and guide-post of die-set can be taken out.This guide-post of die-set operationally, can accelerate heat radiation by louvre 5.This guide-post of die-set because guide pillar main body 1 forms by two sections, and is connected by elastic component 6 between every section, so can reduce impulsive force in the course of work, greatly improves service life, reduces operation cost of enterprises.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.

Claims

1. a guide-post of die-set, comprise for cylindrical guide pillar main body, guide pillar main body two ends are provided with chamfering, it is characterized in that: described guide pillar main body offers toroidal cavity, is equipped with snap ring in groove, and described guide pillar main body offers thermal vias vertically.

2. guide-post of die-set according to claim 1, is characterized in that: described guide pillar main body is connected and composed by elastic component mutually by multi-segment structure.
