The surface of plastic abuts, it is necessary to control dynamic model to be separated with cover half after moulding injection molding, is then driven and pushed up by top plate
Pin is moved towards cover half side, and moulding is ejected；And during thimble ejects moulding, thimble supports with moulding
Connect, and need to apply with larger holding power moulding, deeper thimble vestige can be there are on the moulding so ejected,
Large effect is caused to the surface smoothness of moulding.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of injection mold, it has note
The preferable advantage of plastic surface smoothness.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of injection mold, bag
Cover half and dynamic model are included, die cavity is provided with the cover half, core is provided with the dynamic model, the die cavity fastens shape with core
Into die cavity, the dynamic model is provided with die holder on the end face away from cover half, and top plate is provided with the die holder, is set on the top plate
Have thimble, the thimble flushes through dynamic model and with core, the core include be fixedly connected on top plate loop bar, wear
In top plate and the core bar being connected to inside loop bar is slid, is provided with projection on the top of the core bar, the end face of the projection is wide
Degree is gradually reduced towards cover half side, and the core bar is internally provided with air flue, and the air flue is close to fixed end through projection
Side wall, it is described set boom end on wear be equipped with place projection putting hole.
Pass through above-mentioned technical proposal, when needing moulding being stripped ejection, dynamic model is controlled first away from cover half one
Side is moved, and then controlroof drives loop bar to be moved towards cover half side, and Relative sliding is now produced between loop bar and core bar, is made
The lateral wall for obtaining projection separates with the inner hole wall of putting hole, and now air flue connects with putting hole, and gas flows out from air flue, stream
Through putting hole, most after-blow applies to point to the holding power of cover half side on the lateral wall of moulding, and to moulding, so exists
During loop bar ejects moulding, the active force between loop bar and moulding is reduced so that loop bar is acted on outside moulding

Pass through above-mentioned technical proposal, the number of air flue is some, and during moulding is ejected, multiply gas is simultaneously right
Moulding, which applies, with holding power, can so the active force reduced between loop bar and moulding so that loop bar produces to moulding
Raw pressure significantly reduces, and ensure that the surface smoothness for the moulding that the injection mold is produced.
Preferably, connecting plate is provided between the top plate and die holder, the core bar is fixedly connected on connecting plate, described
Thimble is internally provided with stopper, and the stopper is used for the limit slip locations for limiting core bar.
Pass through above-mentioned technical proposal, core bar are connected with connecting plate, when top plate drives loop bar to move, connecting plate
And the core bar being fixedly connected on connecting plate is not moved, to ensure when top plate moves, between loop bar and core bar
Relative sliding can comparatively fast occur so that gas can flow out and act on moulding from air flue；And set inside thimble
There is the stopper for limiting core bar limit slip locations so that the cavity between loop bar and core bar is smaller, and such gas can
It is very fast to flow out loop bar and act on moulding, the active force between loop bar and moulding is reduced, ensures that the injection mold produces
The surface smoothness of moulding out.
Preferably, the stopper include be arranged on core bar lateral wall restriction groove, be arranged on loop bar madial wall and
For the stop block abutted with limiting groove bottom land.
Pass through above-mentioned technical proposal, when loop bar moves relative to core bar, stop block is slided inside restriction groove
Move；When the side wall and the end abutment of restriction groove of stop block, loop bar drives core bar to move together, and now loop bar is with limiting
Relative sliding is not produced between bar；The stopper so set is simple in construction, more convenient, quick using process.
Preferably, the stop block is rotatably connected to ball on the end of core bar, and the ball is with limiting the interior of groove
Cell wall abuts.
Pass through above-mentioned technical proposal, stop block along the length direction for limiting groove when entering line slip, on stop block end
Ball abutted and ball rotates with limiting groove internal groove side wall, now ball and limit friction between groove as rolling friction,
And force of rolling friction is smaller, it is less prone between such stop block and restriction groove and occurs situation about damaging because of friction, ensured
The service life of the injection mold.
Preferably, the stopper at least two and the circumferentially array setting centered on the axial line of thimble.
Pass through above-mentioned technical proposal, when core bar is slid onto extreme position, multiple stoppers produce restriction to core bar simultaneously
Effect, now core bar is moved with loop bar together, and core bar is less prone to unilateral inclined feelings in core bar moving process
Condition, reduce core bar friction and situation about damaging occur, ensure that the service life of the injection mold.
Preferably, it is provided with oil cylinder on the lateral wall of the dynamic model, the defeated axle of power of the oil cylinder is towards die holder side, institute
State the connecting rod being provided with oil cylinder power output shaft for being connected with top plate.
Pass through above-mentioned technical proposal, when needing to control thimble to eject moulding, control cylinder power output shaft
Towards oil cylinder internal contraction, now connecting rod is moved with top plate, and moulding is ejected；And oil cylinder is fixedly connected
On the lateral wall of dynamic model, and oil cylinder power output shaft, towards die holder side, the oil cylinder so set being capable of effectively less injection
The length of mould, it ensure that the structural compactness of the injection mold.
In summary, the utility model having the beneficial effect that in contrast to prior art：The injection mold has the note of production
The advantages of plastic surface smoothness is preferable, structural compactness is preferable, service life is long.
