Abstract
A kind of mould structure with air blowing assisted demoulding, it includes the throw-out collar below interior core, outside core, formed product chamber and formed product chamber, the interior core is located at the lower section at the top of the formed product intracavitary, the inner mold core inner is equipped with insufflation channel, the interior core is set at top there are four venthole, and the insufflation channel is connected to by the venthole with formed product cavity wall.The utility model at least has many advantages, such as the possibility for reducing deformation of products risk, preventing product sticking to mould, prevents from being sticked on throw-out collar the risk for not falling, reducing press mold when product stripping.
Description
Technical field
The utility model is related to a kind of mould structures with air blowing assisted demoulding.
Background technology
Lid mold is very universal at home now, and lid mold is also all the more ripe, but while rapid development, also companion
As some are difficult to the problem captured.The mould structure of lid is produced in the prior art, and there are some disadvantages：One, product ejects
Stress is more much larger than remaining position at oral area big end when demoulding, it is easy to make product oral area gross distortion, lead to product size not
It is qualified；Two, highly polished product inner wall and part are low because of roughness in demoulding, and face easily forms pull of vacuum with face,
The adhesive force of product is very big at this time, and depending merely on throw-out collar ejection, product top easily occur bad, the case where can not demoulding.If without and
Shi Faxian there is also the case where pressing mold, and mold is caused to damage by pressure, unnecessary loss occurs；Three, product ejection after product with push away
The contact surface of ring also has certain viscous force, and without external forces, product, which is possible to be sticked on throw-out collar, product top occurs
The case where not falling, for the slight needs of situation by the way that repeatedly ejection shaking product falls off back and forth, situation there will be severe pressing mold
Situation.
Utility model content
To solve defect existing for above-mentioned technology, the utility model is intended to provide a kind of mold with air blowing assisted demoulding
Structure at least has the possibility for reducing deformation of products risk, preventing product sticking to mould, prevents from being sticked to when product stripping on throw-out collar not
The advantages that falling, reduce the risk of press mold.
Specific utility model content is as follows：
A kind of mould structure with air blowing assisted demoulding, it includes interior core, outside core, formed product chamber and product
Throw-out collar below forming cavity, the interior core are located at the lower section at the top of the formed product intracavitary, and the inner mold core inner is equipped with
Insufflation channel, the interior core are set at top there are four venthole, the insufflation channel by the venthole and product at
Cavity inner wall is connected to.
Preferably, cooling-water duct, the insufflation channel and the cooling water are equipped between the interior core and outside core
The mutual not unicom in channel.
Further, the venthole is located at the cooling-water duct over top.
Preferably, the interior core bottom is equipped with the air admission hole being connected to insufflation channel.
Advantageous effect：
In the utility model product formed product chamber molding after be ejected when, product in addition to the thrust upward by throw-out collar,
Can also be blown the power generated by entire internal insufflation channel, make product uniform force in demoulding, reduce product change
The risk of shape；Insufflation channel be connected to formed product cavity wall make product demoulding when be beneficial to eliminate product inner wall connect with part
The vacuum state of contacting surface has prevented the possibility of product sticking to mould；After product is ejected, air blowing is also carrying out, and blowing can make at this time
Product is smoothly detached from throw-out collar, prevents product to be sticked on throw-out collar and does not fall, reduces the risk of pressing mold.
Description of the drawings
Fig. 1 is the whole main view cross-sectional view of one preferred embodiment of the utility model.
Reference numeral：
1, interior core；2, outside core；3, formed product chamber；4, throw-out collar；5, insufflation channel；6, venthole；7, cooling water is logical
Road；8, air admission hole.
Specific implementation mode
The utility model is illustrated with reference to specific embodiment：
A kind of mould structure with air blowing assisted demoulding, it include interior core 1, outside core 2, formed product chamber 3 and
The throw-out collar 4 of 3 lower section of formed product chamber, the interior core 1 are located at the lower section of 3 inner top of formed product chamber, the interior core 1
It is internally provided with insufflation channel 5, the interior core 1 is set at top there are four venthole 6, and the insufflation channel 5 is logical by this
Stomata 6 is connected to 3 inner wall of formed product chamber.
Preferably, between the interior core 1 and outside core 2 be equipped with cooling-water duct 7, the insufflation channel 5 with it is described cold
But the mutual not unicom of water channel 7.
Further, the venthole 6 is located at 7 over top of the cooling-water duct.
Preferably, 1 bottom of interior core is equipped with the air admission hole 8 being connected to insufflation channel 5.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
