Abstract
The invention discloses a positioning die ejector sleeve. The positioning die ejector sleeve comprises a flange, a first rod, a second rod, an amplification groove, positioning holes, a positioning groove and a key groove. One end of the flange is connected with the first rod. The amplification groove is formed in the middle portion of the upper face of the flange. The positioning holes are further formed in the upper face of the flange. The four positioning holes are formed in the flange in the front direction, the rear direction, the left direction and the right direction. The positioning groove is formed in the flange. A heat dissipation hole is formed in the first rod. The other side of the first rod is connected with the second rod. The key groove is formed in the second rod. An annular groove is formed in the inner hole wall of the ejector sleeve. The ejector sleeve is simple, safe and reliable, the phenomenon of eccentricity or jamming between the ejector sleeve and a centre can be effectively avoided in the using process, the quality of products is guaranteed accordingly, and the machining efficiency is improved.
Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of jig ejector sleeve.
Background technology
Ejector sleeve is also the thimble of push pipe, hollow, general and thimble with the use of, be called ejector pin assembly, be plastic mould
One in accessory, has straight body type ejector sleeve and notch cuttype ejector sleeve etc., and in use, ejector sleeve is enclosed within thimble, and ejector sleeve can move up and down by thimble relatively, thus is ejected by the product wrapped on thimble.But the ejector sleeve used at present, especially notch cuttype ejector sleeve, it is internal because being provided with step, therefore thimble is when moving relative to ejector sleeve, if thimble does not has the concentricity enough with ejector sleeve holding, or the precision of thimble and ejector sleeve somewhat has deviation, will result in thimble axis deviation ejector sleeve axle center, so that ejector sleeve and thimble are when relative movement, can the problems such as outlet boring is eccentric, friction change is big.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of jig ejector sleeve, and it is reasonable in design, simple in construction, solves ejector sleeve and is difficult to the problems such as location, the easily friction of ejector sleeve inwall.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is to provide a kind of jig ejector sleeve, comprising: flange, first body of rod, second body of rod, amplification groove, hole, location, locating slot and keyway；One end of described flange is connected with first body of rod；The upper Middle face of described flange offers amplification groove；The above of described flange is additionally provided with hole, location；Described location Kong Yousi is individual and is arranged on flange in four direction all around respectively；Described flange is provided with a locating slot；Described first body of rod is provided with a louvre；The another side of described first body of rod and second body of rod are connected；Described keyway is arranged on second body of rod；Described annular groove is arranged on ejector sleeve inner hole wall.
Preferably, described keyway is U-shaped；
Preferably, described annular groove has one or more, and the surface being provided with kollag and kollag in annular groove is concordant with guide pin bushing inwall.
The invention has the beneficial effects as follows: present configuration location simple, easily fabricated, easy, guarantee installation accuracy, and ejector sleeve inwall are provided with kollag, reduce the friction of barrel and attached article, extend the service life of ejector sleeve, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention a kind of jig ejector sleeve；
In accompanying drawing, the labelling of each parts is as follows: 1, flange；2, first body of rod；3, second body of rod；4, amplification groove；5, hole, location；6, locating slot；7, keyway.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to accompanying drawing 1, the embodiment of the present invention includes: flange 1, first body of rod, 2, second body of rod 3, amplification groove 4, hole 5, location, locating slot 6 and keyway 7；One end of described flange 1 is connected with first body of rod 2；The upper Middle face of described flange 1 offers amplification groove 5；The above of described flange 1 is additionally provided with hole 5, location；Hole, described location 5 has four and is arranged on flange 1 in four direction all around respectively；Described flange 1 is provided with a locating slot 6；Described first body of rod 2 is provided with a louvre；Another side and second body of rod 3 of described first body of rod 2 are connected；Described keyway 7 is arranged on second body of rod 3；Described annular groove is arranged on ejector sleeve inner hole wall.
Described locating slot 6 can quickly make ejector sleeve position, and then hole 5, location is directly fixed ejector sleeve；When ejector sleeve is started working, ejector sleeve inwall reduces inner wall abrasion by the kollag stored in annular groove；Louvre on described first body of rod 2 can heat fricative to ejector sleeve inwall dispel the heat；Keyway 7 on described second body of rod 3 can with connector with the use of.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
