Abstract
The utility model discloses an ejector sleeve. The ejector sleeve comprises an ejector sleeve body, wherein a cup head screw is arranged at one end of the ejector sleeve body; one end, which is provided with the cup head screw, of the ejector sleeve body forms a tail end, and the other end of the ejector sleeve body forms a head end; the center of the ejector sleeve body is provided with a through hole which is coaxial with the ejector sleeve body; the radius of the through hole gradually increases from the middle part of the ejector sleeve body to the tail end of the ejector sleeve body. The ejector sleeve is simple in structure and is safe and reliable; a phenomenon that the ejector sleeve and a thimble are eccentric or are clamped in the use process can be avoided effectively, so that the quality of products is guaranteed and the processing efficiency is improved.
Description
Technical field
The utility model relates to a kind of ejector sleeve.
Background technology
Ejector sleeve also is the thimble of push pipe, hollow, general and thimble is used in conjunction with, be called the ejector pin assembly, a kind of in the plastic mould accessory, straight body type ejector sleeve and notch cuttype ejector sleeve etc. are arranged, and in use, ejector sleeve is enclosed within on thimble, ejector sleeve thimble relatively moves up and down, thereby the product that will wrap on thimble ejects.
But current used ejector sleeve, especially notch cuttype ejector sleeve, it is inner because be provided with step, therefore thimble is when ejector sleeve moves, if thimble does not have and ejector sleeve keeps enough concentricitys, perhaps the precision of thimble and ejector sleeve has deviation a little, will cause thimble axis deviation ejector sleeve axle center, thereby make ejector sleeve and thimble when relatively moving, can outlet eccentric, the holes of boring bad, thimble can be stuck in ejector sleeve, or thimble front end collapse angle, fillet, and product appearance is bad, even make a whole set of mould cause scrapping of mould because of ejector sleeve assembly stuck.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of ejector sleeve, can not produce stuck phenomenon with thimble.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of ejector sleeve, comprise the ejector sleeve body, this ejector sleeve body one end is provided with hexagonal socket head cap screw, the end that described ejector sleeve body is provided with hexagonal socket head cap screw forms tail end, its other end forms head end, described ejector sleeve body center is provided with the through hole with this ejector sleeve body coaxial line, and at described ejector sleeve body middle part, the radius of a section to the tail end of described ejector sleeve body becomes large to described through hole gradually.
As further improvement of the utility model, described through hole is identical to the radius size of a section of first section of described ejector sleeve body at described ejector sleeve body middle part.
As further improvement of the utility model, described ejector sleeve be straight body type ejector sleeve and notch cuttype ejector sleeve one of them.
The beneficial effects of the utility model are: simple in structure, safe and reliable, and can effectively avoid in use procedure between ejector sleeve and thimble bias or stuck phenomenon to occur, thereby guarantee the quality of product, promote working (machining) efficiency.
The accompanying drawing explanation
Fig. 1 is straight body type ejector sleeve structural representation described in the utility model;
Fig. 2 is notch cuttype ejector sleeve structural representation described in the utility model.
By reference to the accompanying drawings, make the following instructions:
1---ejector sleeve body 2---hexagonal socket head cap screw
3---tail end 4---head end
5---through hole
The specific embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
A kind of ejector sleeve, can be straight body type ejector sleeve (see figure 1) or notch cuttype ejector sleeve (see figure 2), comprise ejector sleeve body 1, this ejector sleeve body one end is provided with hexagonal socket head cap screw 2, the end that described ejector sleeve body is provided with hexagonal socket head cap screw forms tail end 3, its other end forms head end 4, and described ejector sleeve body center is provided with the through hole 5 with this ejector sleeve body coaxial line, it is characterized in that: at described ejector sleeve body middle part, the radius of a section to the tail end of described ejector sleeve body becomes large to described through hole gradually.Like this, in use, because the radius of through hole in the part near ejector sleeve body tail end gradually changes, form gradient, thereby, when thimble and ejector sleeve are relatively moved, can adjust in time their concentricity, thereby can not be offset, phenomenon occurs to cause thimble to damage or stuck etc.
Preferably, described through hole is identical to the radius size of a section of first section of described ejector sleeve body at described ejector sleeve body middle part.
Claims (3)
1. an ejector sleeve, comprise ejector sleeve body (1), this ejector sleeve body one end is provided with hexagonal socket head cap screw (2), the end that described ejector sleeve body is provided with hexagonal socket head cap screw forms tail end (3), its other end forms head end (4), described ejector sleeve body center is provided with the through hole (5) with this ejector sleeve body coaxial line, it is characterized in that: at described ejector sleeve body middle part, the radius of a section to the tail end of described ejector sleeve body becomes large to described through hole gradually.
2. ejector sleeve according to claim 1 is characterized in that: described through hole is identical to the radius size of a section of first section of described ejector sleeve body at described ejector sleeve body middle part.
3. ejector sleeve according to claim 1 and 2 is characterized in that: described ejector sleeve be straight body type ejector sleeve and notch cuttype ejector sleeve one of them.
