Description
Technical field
The present invention relates to a kind of mold more particularly to a kind of injection mold location structures.
Background technology
At present, in injection mold, positioning when dynamic model and cover half mold all is by being located in them in a module
The positioning guide column positioning guide sleeve that is located in another module of insertion come what is realized, under normal circumstances, positioning guide column is cylinder
Shape, the endoporus for positioning guide sleeve are circular holes.However, injection molding machine is often injection moulded a plastic article, the positioning on injection molding mould fixed die
The positioning guide sleeve that guide post is just passed in and out on dynamic model is primary, often a working day get off, injection mould open-close mould up to hundreds of times even
It thousands of times, results in mutually rubbing between positioning guide column and positioning guide sleeve in this way, the two gap constantly increases；When the two gap reaches
During to certain value, dynamic model and cover half molding will will appear problem of misalignment, cause position inaccurate, influence product quality, thus anxious
It needs to solve.
Invention content
In view of this, the object of the present invention is to provide a kind of injection mold location structure, so as to solve in background technology
The problem of mentioning.
The present invention solves above-mentioned technical problem by following technological means：
A kind of injection mold location structure, including positioning guide column and locating channel, it is characterised in that：The positioning guide column is
One frustum structure offers a positioning hole in the top circle centre position of the positioning guide column, and the location hole extends downwardly connection one
Round air cavity, the air cavity circumferentially radially connect several cylinder slideways, and the cylinder slideway is led through the positioning
Column is provided with sliding block in the slideway；The end of the sliding block is equipped with inclined-plane, the gradient on the inclined-plane and the positioning guide column
Be consistent；It is fixedly connected with and the matched positioning plug-in unit of the location hole in the slot bottom circle centre position of the locating channel.
Further, the opening of the location hole is additionally provided with chamfering.
Further, the positioning plug-in unit is equipped with sealing ring.
The present invention compares compared with the prior art to be had：The positioning guide column of frustum structure is in molding moment convenient for positioning guide sleeve
Contact surface is detached from, and is effectively alleviated friction between the two, is improved the service life of positioning guide column.It is approached in positioning guide sleeve
During positioning guide column, after certain distance is reached, positioning plug-in unit will be inserted into location hole, while compress in air cavity slowly
Air, the air of air cavity pushes the sliding block being located in cylinder slideway while compression, sliding block made slowly to skid off positioning guide column
And the inner wall of positioning guide sleeve is moved closer to, when upper and lower mould fits like a glove, sliding block is just against positioning and leads under the influence of air pressure
On the inner wall of set and apply certain atmospheric pressure, play the role of certain locking, prevent to misplace, and sliding block contracts in molding
It returns, it is easy to operate, it is easily changed wear-out part.
Description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is positioning guide column overlooking the structure diagram of the present invention.
Specific embodiment
Below with reference to attached drawing, the present invention is described in detail：
As shown in Figs. 1-2：
A kind of injection mold location structure, including positioning guide column 1 and locating channel 2, it is characterised in that：The positioning guide column
1 is a frustum structure, offers a positioning hole 3 in the top circle centre position of the positioning guide column 1, the location hole 3 extends downwardly
The round air cavity 4 of connection one, the air cavity 4 circumferentially radially connect several cylinder slideways 5, and the cylinder slideway 5 runs through
The positioning guide column 1 is provided with sliding block 6 in the slideway 5；The end of the sliding block 6 be equipped with inclined-plane 7, the inclined-plane 7 it is oblique
Degree is consistent with the positioning guide column 1；It is fixedly connected with and the location hole in the slot bottom circle centre position of the locating channel 2
3 matched positioning plug-in units 8.
Further, the opening of the location hole 3 is additionally provided with chamfering.
Further, the positioning plug-in unit 8 is equipped with sealing ring.
The present invention compares compared with the prior art to be had：The positioning guide column of frustum structure is in molding moment convenient for positioning guide sleeve
Contact surface is detached from, and is effectively alleviated friction between the two, is improved the service life of positioning guide column.It is approached in positioning guide sleeve
During positioning guide column, after certain distance is reached, positioning plug-in unit will be inserted into location hole, while compress in air cavity slowly
Air, the air of air cavity pushes the sliding block being located in cylinder slideway while compression, sliding block made slowly to skid off positioning guide column
And the inner wall of positioning guide sleeve is moved closer to, when upper and lower mould fits like a glove, sliding block is just against positioning and leads under the influence of air pressure
On the inner wall of set and apply certain atmospheric pressure, play the role of certain locking, prevent to misplace, and sliding block contracts in molding
It returns, it is easy to operate, it is easily changed wear-out part.
The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be understood by those of ordinary skill in the art that, it can modify to technical scheme of the present invention
Or equivalent replacement, without departing from the objective and range of technical solution of the present invention, the claim in the present invention should all be covered
In range.
