Abstract
The invention relates to an improved guide pillar. The improved guide pillar comprises a guide pillar body, wherein a center hole is formed in the guide pillar body, the circumferential outer surface of the guide pillar body is provided with thread-shaped heat dissipation oil grooves, and oil inlets of the heat dissipation oil grooves are arranged on the upper end of the guide pillar body; an oil outlet is arranged on the lower end of the guide pillar body, the groove cross section of each heat dissipation oil groove is U-shaped, and the distance between the adjacent heat dissipation oil grooves is 1.2-1.8cm. The improved guide pillar provided by the invention has the advantages that due to the arrangement of the heat dissipation oil grooves, heat conduction oil is injected from the oil inlets, so that the temperature between the guide pillar and a guide sleeve is effectively reduced, and the service life of the improved guide pillar is prolonged.
Description
Technical field
The present invention relates to the pillar for mold field, relate in particular to a kind of modified guide pillar.
Background technology
During Design of Dies, a plurality of guide pillars and bushes need to be set on mould bases, these guide pillars and bushes are corresponding and cooperatively interact one by one, so that, when matched moulds, guarantee its precision.This is general knowledge well-known to those skilled in the art.Therefore, in most cases, people can emphasize precision and the intensity of guide pillars and bushes, so that improve the precision of mould, then reach the purpose that improves machining accuracy.But, particularity due to mould, add that guide pillars and bushes itself is made of metal, when mold work, friction between guide pillars and bushes adds the workflow of mold itself, particularly plastic mould, itself just have heating, insulation etc. step, makes the guide pillars and bushes temperature when mold work be arranged on mould raise gradually.When its temperature is elevated to certain value, deformation may occur in guide pillars and bushes, and the friction that this has not only aggravated between guide pillars and bushes raises temperature again, then makes the mould location difference occur; And the wearing and tearing that the friction aggravation brings may be that guide pillars and bushes is scrapped in advance because of the wearing and tearing aggravation.But, do not have comparatively effective method in prior art, only just control by rule of thumb the temperature of guide pillars and bushes, reliability is poor.
Summary of the invention
The objective of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of modified guide pillar.
The present invention is achieved through the following technical solutions:
A kind of modified guide pillar, comprise the guide pillar body, described guide pillar body is provided with centre bore, and the circumferential outer surface of described guide pillar body is provided with and is screw-shaped heat radiation oil groove, the oil-in of described heat radiation oil groove is in the upper end of double-screw bolt body, and oil-out is in the lower end of double-screw bolt body.
As the preferred technical solution of the present invention, the slot cross-section of described heat radiation oil groove is " U " type.
As the preferred technical solution of the present invention, the distance between described adjacent heat radiation oil groove is 1.2-1.8cm.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by the heat radiation oil groove is set, injects conduction oil from oil-in, effectively reduces the temperature between guide pillar and guide pin bushing, improves its service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
Described a kind of modified guide pillar, comprise guide pillar body 1, described guide pillar body 1 is provided with centre bore 2, and the circumferential outer surface of described guide pillar body 1 is provided with and is screw-shaped heat radiation oil groove 3, the oil-in of described heat radiation oil groove 3 is in the upper end of double-screw bolt body 1, and oil-out is in the lower end of double-screw bolt body 1.
The slot cross-section of described heat radiation oil groove 3 is " U " type, and the distance between described adjacent heat radiation oil groove 3 is 1.5cm.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
