Abstract
The utility model relates to a can improve vacuum structure that takes out that injection mold is stranded gas, by the vacuum pump interface of bleeding, take out main air flue around, the mould connect bleed, mould induction port and limit air guide say and constitute, the vacuum pump interface of bleeding install in the outside of front mould and back mould and this interface meets with the vacuum pump that has a flow control valve, and front mould wherein corresponds with each outward flange of mould of back mould sets up a mould induction port and set up limit air guide way peripheral the encircleing of mould, this limit air guide is said and is taken out main air flue and is linked together, and simultaneously, the mould was connected and is bled around the limit air guide way department of meeting of taking out main air flue and corresponding was equipped with. The utility model discloses beneficial effect does: the flow dimension regulated flow comes the inside air of suction mould as required, that can solve any machine production here is stranded the bad problem that gas causes because of the mould.
Description
Technical field
This utility model relates to injection mold technology, particularly relates to a kind of injection mold that improves and is stranded taking out very of gas
Hollow structure.
Background technology
Mould is mainly made up of running gate system, thermoregulating system, forming part and constitutional detail.Injection mold by
Dynamic model and cover half two parts composition, dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on note
Penetrate on the fixed form of forming machine；When injection moulding, dynamic model constitutes running gate system and die cavity with cover half Guan Bi,
During die sinking, dynamic model separates with cover half to take out goods.
This case it is important to note that at present, when injection molded produces, mould close after mould in
There is air in portion, thus, often cause because inner air cannot be discharged when injection mo(u)lding and lack material or burn
Bad, or have air discharge duct, but air discharge duct is excessive, and melt plastic cement forms rim charge (hair in easily entering air discharge duct
Limit) bad；Air discharge duct is too small, and in easily there is mould, air has little time to discharge and cause and lack material or burn bad；
Additionally, also can because of after plastic warp high-temperature fusion mobility become big, flow velocity can not be stablized and uncontrollable.
Therefore, for the above, need prior art is reasonably improved.
Utility model content
For disadvantages described above, this utility model provides a kind of injection mold that improves to be stranded the Vacuuming structure of gas,
To solve the problem causing product bad at present because mould inside there is air, and solve plastic cement industry
The bad difficult problem that injecting molding die causes due to tired gas.
For achieving the above object, this utility model is by the following technical solutions:
A kind of injection mold that improves is stranded the Vacuuming structure of gas, by aspirator vacuum pump interface, take out main airway,
Front and back mould connects air exhaust duct, mold suction mouth and limit airtube composition, and described aspirator vacuum pump interface is installed
Connect with the vacuum pump with flow control valve with outside and this interface of rear mold in front mould, front mould therein
Corresponding with each outward flange of the mould of rear mold offer a mold suction mouth and in mould periphery around arranging limit
Airtube, this limit airtube is connected with taking out main airway；Meanwhile, main airway and corresponding limit inducing QI are taken out described in
Joint, road is provided with before and after's mould and connects air exhaust duct.
Described main airway be set to one or at least two and each with an aspirator vacuum pump interface phase
Connect；Before and after described, mould connection air exhaust duct is perpendicular to front mould and rear mold upper surface.
The injection mold that improves described in the utility model is stranded the having the beneficial effect that of Vacuuming structure of gas
(1) by installing a vacuum pump having flow control valve outside injection moulding machine, need to discharge at mould
Bore a small de-air hole (depending on hole size is according to material category) at air, outside mould, fill an interface, will
Vacuum pump air entry is connected with vent bore interface, and vacuum pump action is connected with folding mould or injection action
Dynamic, before action of injection starts, vacuum pump starts air in sucking-off mould；
(2) employing has the vacuum pump of flow regulating function, can carry out sucking-off mould by uninterrupted regulation flow as required
Tool inner air；
(3) injection machines only need to install a vacuum pump, just can solve any this machine produce because of mould
The bad problem being stranded gas and cause.

Detailed description of the invention
As Figure 1-3, the improved injection mold described in this utility model embodiment is stranded the evacuation knot of gas
Structure, by aspirator vacuum pump interface 3, take out main airway 4, front and back mould connect air exhaust duct 5, mold suction mouth 6 with
And limit airtube 7 forms, described aspirator vacuum pump interface 3 is installed on the outside of front mould 1 and rear mold 2, its
In front mould 1 corresponding with each outward flange of the mould of rear mold 2 offer a mold suction mouth 6 and at mould
Peripheral around arranging limit airtube 7, this limit airtube 7 is connected with taking out main airway 4, and this takes out main airway 4
It is set to two and each connect with an aspirator vacuum pump interface 3；Meanwhile, main airway 4 is taken out described in
Being provided with before and after's mould with corresponding limit airtube 7 joint and connect air exhaust duct 5, before and after being somebody's turn to do, mould connects air exhaust duct 5
It is perpendicular to front mould 1 and rear mold 2 upper surface.
Improved injection mold described in above this utility model embodiment is stranded the Vacuuming structure of gas, by
One vacuum pump having flow control valve is installed outside injection moulding machine, needs to bore one at air-out at mould
Small de-air hole (depending on hole size is according to material category), fills an interface, by vacuum pump air entry outside mould
Being connected with vent bore interface, vacuum pump action is connected with folding mould or injection action, action of injection
Before beginning, vacuum pump starts air in sucking-off mould.
The above-mentioned description to embodiment is for the ease of those skilled in the art it will be appreciated that and answer
Using this case technology, these examples obviously can be made various amendment by person skilled in the art easily, and
General Principle described herein is applied in other embodiments without through performing creative labour.Therefore,
This case is not limited to above example, and those skilled in the art, according to the announcement of this case, makes for this case
Improve and amendment, such as, the structure of mould, front and back mould or type, vacuum pump structure or type, each
The shape of pore or air flue and structure etc.,
Additionally, this case embodiment and figure thereof use the structure that main airway and vacuum pump interface are set to two,
According to mould structure complexity difference needs, one or some, therefore, every similar structures can be set
Conversion, if without producing beyond the beneficial effect outside this case scope, the most all should be in the protection domain of this case.
