Abstract
The invention discloses a kind of ejector sleeve, comprising: the first main body, the second main body and ejector sleeve seat；Described first main body is connected with the second cylinder；Described second main body is connected with ejector sleeve seat；The diameter of described first main body is less than the diameter of the second main body；Described first main body and the second main body are provided with guide hole and guide groove；Described first main body and the second main center are provided with and the through hole of this ejector sleeve body coaxial line；The through hole of described second main body is more than the through hole of the first main body.This ejector sleeve simple in construction, safe and reliable, eccentric between ejector sleeve and thimble or stuck phenomenon can be prevented effectively from during use and occur, thus ensure the quality of product, promote working (machining) efficiency.
Description
Technical field
The present invention relates to mould ejector sleeve field, particularly relate to a kind of ejector sleeve.
Background technology
Ejector sleeve and thimble support the use and are called ejector pin assembly, are the one in plastic mould accessory.Ejector sleeve is i.e. to produce
There are through hole or the blind hole of circle on product, and glue position must be provided with ejecting a kind of liftout attachment metal fittings used.Due to
Ejector sleeve generally to match with supporting thimble during using, due to the characteristic of its structure, in actual use process
In, the operation of thimble usually there will be stuck phenomenon, once thimble locking, the most then rectified it by conventional method
Just, allowing it can be the most properly functioning, so will affect the progress of production, the serious whole product that results even in goes out
Do not come, cause product rejection, mould can cause a certain degree of infringement even damage simultaneously yet, so will result in bigger
The loss of degree, thus existing ejector sleeve needs to be improved.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of ejector sleeve, and it is reasonable in design, and simple in construction solves thimble
The problem the most stuck with ejector sleeve.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is to provide a kind of ejector sleeve, comprising: first
Main body, the second main body and ejector sleeve seat；Described first main body is connected with the second cylinder；Described second main body is connected with ejector sleeve seat；Institute
State the diameter diameter less than the second main body of the first main body；Described first main body and the second main body are provided with guide hole and guide groove；Institute
State the first main body and the second main center is provided with and the through hole of this ejector sleeve body coaxial line；The through hole of described second main body is more than the
The through hole of one main body.
Preferably, described ejector sleeve is an entirety；
Preferably, described ejector sleeve be straight body type ejector sleeve and notch cuttype ejector sleeve one of them.
The invention has the beneficial effects as follows: ejector sleeve simple in construction of the present invention, safe and reliable, take charge of during use can be prevented effectively from
Eccentric or stuck phenomenon generation between cylinder and thimble, thus ensure the quality of product, promote working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of ejector sleeve of the present invention；
In accompanying drawing, the labelling of each parts is as follows: 1, the first main body；2, the second main body；3, ejector sleeve seat；4, guide hole；5, guide groove.
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 energy
It is 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: the first main body the 1, second main body 2 and ejector sleeve seat 3；Described first is main
Body 1 is connected with the second cylinder 2；Described second main body 2 is connected with ejector sleeve seat 3；The diameter of described first main body 1 is less than the second main body
The diameter of 2；Described first main body 1 and the second main body 2 are provided with guide hole 4 and guide groove 5；In described first main body 1 and the second main body 2
The heart is provided with and the through hole of this ejector sleeve body coaxial line；The through hole of described second main body 2 is more than the through hole of the first main body 1.
Further, described ejector sleeve is an entirety；
Further, described ejector sleeve be straight body type ejector sleeve and notch cuttype ejector sleeve one of them.
When deployed, ejector sleeve seat 3 is connected on die machine, allows thimble and ejector sleeve keep absolute parallel, the second main body 2
Endoporus directly can prevent the situation of thimble locking more than the diameter of the first main body 1 endoporus；Ejector sleeve simple in construction of the present invention, safety
Reliably, eccentric or stuck phenomenon generation between ejector sleeve and thimble during use can be prevented effectively from, thus ensure the quality of product,
Promote working (machining) efficiency.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks
Territory, is the most in like manner included in the scope of patent protection of the present invention.
