Abstract
The invention discloses a mould guide device which comprises a guide column and a guide sleeve, wherein the guide column and the guide sleeve are fixed on an upper mould plate and a lower mould plate, respectively, the guide column is in a cylindrical shape, the guide sleeve is in a ring cylinder shape, and an annular limiting groove is formed in the bottom of the inner wall of the guide sleeve; a ball bearing bushing is arranged in the guide sleeve in a clearance fit way; a limiting bulge which corresponds to the annular limiting groove is formed at the bottom of the ball bearing bushing; an elastic part is arranged between the limiting bulge and the annular limiting groove; the ball bearing bushing comprises a body and ball bearings; the body is in the ring cylinder shape, and a plurality of circular through grooves are formed in the side wall of the body; the ball bearings are contained in the circular through grooves and can roll freely. According to the mould guide device, the ball bearing bushing is arranged in the guide sleeve in the clearance fit way, conventional line friction or surface friction is changed into rolling friction, so that the positioning and the guiding can be realized easily, small errors are achieved, the quality stability of a product is ensured, the service life of the guide column and the service life of the guide sleeve are prolonged, and the economic benefit is outstanding.
Description
Technical field
The present invention relates to a kind of mold guide sleeve, belong to mould applications.
Background technology
In mould applications, guide pin bushing and guide pillar form the guider of mould jointly, are used for guaranteeing that upper and lower mould is so that position relationship is involutory accurately.Owing to constantly doing relative motion between patrix and counterdie, so must have certain gap between guide pillar and guide pin bushing to guarantee accessible motion, existing mould is all the relative motion that guide pillar, guide pin bushing are done line or face friction, and excesssive gap can cause locating inaccurate, and error is large; The too small serious wear that can increase friction, make guide pillar guide pin bushing in gap, has reduced service life, increased cost input, and the replacing of guide pillar guide pin bushing quite bothers.Given this, in the urgent need to a kind of novel, error is little, locate easy, durable mould guider.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of easy location, guiding accurately, error is little, mould guider little, long service life weares and teares.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Mould guider, comprise: the guide pillars and bushes that is individually fixed in cope match-plate pattern and lower bolster, described guide pillar is cylindrical, described guide pin bushing is that the inwall bottom of annulus cylindricality and guide pin bushing is formed with an annular spacing groove, described guide pin bushing internal clearance coordinates a ball sleeve, the bottom of described ball sleeve is formed with the spacing preiection corresponding with annular spacing groove, between described spacing preiection and annular spacing groove, is provided with elastic component; Described ball sleeve comprises body and ball, wherein body be annulus cylindricality and sidewall on be formed with multiple circular grooves, described ball is contained in circular groove and can Free-rolling.
Aforementioned spacing preiection is and the integrated annular protrusion of ball sleeve body.
Aforementioned spacing preiection is and the integrated multiple projections of ball sleeve body that described multiple projections are arranged on same periphery.
Aforementioned elastic parts is the elastomeric pad of being made up of rubber.
Aforementioned elastic parts is jump ring, and described jump ring one end props up spacing preiection, and the other end props up annular spacing groove.
The outer wall middle and lower part of aforementioned guide pin bushing forms a locating slot.
The top of aforementioned ball sleeve exceeds the top of described guide pin bushing.
The rectification error of the matched in clearance of aforementioned guide pin bushing and ball sleeve is below 2 μ m.
Usefulness of the present invention is: mould guider of the present invention, guide pin bushing internal clearance coordinates a ball sleeve, traditional line friction or face friction are changed into rolling friction, make location and guiding become easy realization, and error is little, guarantee the stability of product quality, also extended the service life of guide pillars and bushes simultaneously, remarkable in economical benefits.
Accompanying drawing explanation
Fig. 1 is the structural representation of mould guider of the present invention;
Fig. 2 is the top view of mould guider of the present invention.
The implication of Reference numeral in figure: 1, guide pillar, 2, guide pin bushing, 3, ball sleeve, 4, body, 5, ball, 6, spacing preiection, 7, annular spacing groove, 8, elastic component, 9, locating slot.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1 and Fig. 2, mould guider of the present invention, comprise: be individually fixed in guide pillar 1 and the guide pin bushing 2 of cope match-plate pattern and lower bolster, at the interior ball sleeve 3 that arranges of guide pin bushing 2, guide pillar 1 is columniform, guide pin bushing 2 and ball sleeve 3 are annulus cylindricality, ball sleeve 3 adopts matched in clearance with guide pin bushing 2, and particularly, ball sleeve 3 comprises body 4 and ball 5, on the sidewall of body 4, be formed with multiple circular grooves, ball 5 is just in time contained in and in circular groove, can not drops out and can Free-rolling.So, the guiding of guide pillar 1 and guide pin bushing 2 and location just become and are easy to realize, and adopt ball 5 to realize rolling friction, have greatly reduced the wearing and tearing of guide pillar 1 and guide pin bushing 2, have extended service life.Preferably, the top of ball sleeve 3 exceeds the top of described guide pin bushing 2, to further facilitate location.
For guide pin bushing 2 and ball sleeve 3 are worked good, inwall bottom at guide pin bushing 2 is formed with an annular spacing groove 7, correspondingly be formed with the spacing preiection corresponding with annular spacing groove 76 in the bottom of ball sleeve 3, and be provided with elastic component 8 between spacing preiection 6 and annular spacing groove 7.Are matched in clearance due to ball sleeve 3 and guide pin bushing 2 but also are provided with elastic component 8, so, even if there is a little deviation the position of guide pin bushing 2 and guide pillar 1, also can automatically correct by the displacement of ball sleeve 3, preferred as one, ball sleeve 3 is below 2 μ m (micron) with the rectification error of the matched in clearance of guide pin bushing 2.
As concrete structure, spacing preiection 6 is and the integrated annular protrusion of ball sleeve 3 body 4, can be also and the integrated multiple projections of ball sleeve 3 body 4 that multiple projections are arranged on same periphery.Elastic component 8 can be the elastomeric pad of being made up of rubber, can be also jump ring, and jump ring one end props up spacing preiection 6, and the other end props up annular spacing groove 7.Like this, thus ball sleeve 3 just can be realized displacement rectification error by compression elastic piece 8.
Further, as shown in Figure 1, the outer wall middle and lower part of guide pin bushing 2 forms a locating slot 9, to guide pin bushing 2 is installed on to position accurately.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
