Description
Technical field
A kind of injection mold air pressure ejecting structure is the utility model is related to, belongs to injection mold technology.
Background technology
With the extensive use of plastic products, its structure is also more next complicated, for some thin-walleds or large scale plastic,
When injection mold molds, plastic is easy to adsorb on die, flexural deformation when causing the moulding to eject, or even rupture.Mould
Tool surface roughness has a significant impact to plastic ejection, and die surface is too coarse, and frictional force is big during ejection, and ejection is difficult；Mould
Surface is too smooth, product fitting die surface, forms vacuum, and ejection is also difficult, therefore the roughness of die surface needs strict control
System, but still have the problem of ejection is difficult.
Plastic ejects an important step as injection moulding process, and conventional pushing method uses oil hydraulic power, mostly pushed up
The mode of pin, push rod, jacking block etc. " resisting stubbornly ", ejection plastic is forced under ejector retainner plate effect.Oil pressure needed for such a pushing method
System architecture is complicated, requires higher to environmental condition, moreover, it is broken to easily cause plastic top for the difficult plastic of ejection.Meanwhile
The reciprocating action of ejector retainner plate is needed to take substantial amounts of die space, and such a pushing method is applicable just for main mould insert, nothing
Method is used at the mold mechanisms such as core pulling, oblique top.
In addition, for the back-off structure of plastic, the mechanisms such as core pulling, oblique top are designed on mould, if inside and outside plastic
There is back-off structure side, then the design of mould and the demoulding of product all can be complicated a lot, if oblique top and core-pulling mechanism are not easy
Depart from plastic, now traditional pushing method is difficult to solve such case, and this is due to the ejection such as thimble, push rod, jacking block
Ejector retainner plate needed for structure can not be arranged.
The content of the invention
The purpose of this utility model is to provide a kind of injection mold air pressure ejecting structure, and substituting oil pressure using air pressure realizes work
The demoulding ejection of part, mould is simple in construction without ejector retainner plate, and relatively low, stripping result wider using face is required to external condition
It is good.
The utility model takes following technical scheme：
A kind of injection mold air pressure ejecting structure, including mold insert 2, jacking block 3, jacking block connecting rod 4, back-moving spring 5, connecting rod bonnet
6；The inside of mold insert 2 is provided with gas channels, jacking block connecting rod movable passageway；Gas channels and jacking block connecting rod movable passageway are arranged on
Inside mold insert 2, the top of jacking block connecting rod 4 is connected with jacking block 3, and bottom is connected with connecting rod bonnet 6, and the both ends of back-moving spring 5 are supported respectively
The firmly end face of connecting rod bonnet 6 and jacking block connecting rod movable passageway.
Further, in addition to framed 1, the mold insert 2 is inlayed on framed 1, and the gas channels extend to mould
Frame 1 is simultaneously connected with the tracheae 7 of framed outside.
Further, the tracheae 7 is connected on the gas channels by air pipe interface 8.
Further, the jacking block connecting rod 4, gas channels, back-moving spring, set straight up.
Further, mold insert 2 is placed in framed 1, and mold insert 2 is sealed with framed 1 at jacking block tie rod holes by sealing ring 9
Connection.
Further, the front and back end of jacking block connecting rod 4 is coupled with jacking block 3, connecting rod bonnet 6 respectively by screw thread, connecting rod bonnet 6
Open interior hexagonal groove.
The beneficial effects of the utility model are：
1) blowed air among mould and plastic so as to eject plastic, overcome true between plastic and mould by air inlet pipe
Empty suction-operated, by gas flexibility, plastic is uniformly acted on, the top for avoiding thimble from easily occurring when directly pushing up plastic is broken, top
Phenomena such as convex.
2) the external complex device such as ejector retainner plate is avoided, need to only the mold component for needing to eject plastic be coupled by tracheae
Place, can be applied to the mold component of the inconvenience push rod such as oblique top, core pulling, have the characteristics of being widely used.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model injection mold air pressure ejecting structure.
In figure, 1. is framed, 2. mold inserts, 3. jacking blocks, 4. jacking block connecting rods, 5. back-moving springs, 6. connecting rod bonnets, 7. tracheaes, and 8.
Air pipe interface, 9. sealing rings, 10. plastics.
Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of injection mold air pressure ejecting structure, including mold insert 2, jacking block 3, jacking block connecting rod 4, back-moving spring 5,
Connecting rod bonnet 6；The inside of mold insert 2 is provided with gas channels, jacking block connecting rod movable passageway；Gas channels and the movement of jacking block connecting rod are logical
Road is arranged on inside mold insert 2, and the top of jacking block connecting rod 4 is connected with jacking block 3, and bottom is connected with connecting rod bonnet 6, and the two of back-moving spring 5
End is respectively held against the end face of connecting rod bonnet 6 and jacking block connecting rod movable passageway.
In this embodiment, with continued reference to Fig. 1, in addition to framed 1, the mold insert 2 is inlayed on framed 1, described
