Description
Technical field
The present invention relates to rubber injection to connect angle mold, and particularly a kind of weather strip for automobile injection that built-in can be buckled connects angle
Mould.
Background technology
The edge of automobile window glass is enclosed with the sealing strip of rubber material, and the part of the sealing strip on the corner is usual
It is compressing that angle mould is connect by dedicated injection.
Existing weather strip for automobile injection, which connects angle mould, includes upper die and lower die, middle template and core.Middle template and core activity
In lower die, upper mold can be engaged or separate with lower die, when upper mold is engaged with lower die, middle template and core be located at upper mold and
Between lower die.Upper die and lower die, middle template and core coordinate, and form the cavity for accommodating sealing strip.
In use, injection connect angle mould upper and lower mould be separately mounted to injection connect on the upper and lower hot plate of angle machine；Injection connects angle
Machine controls upper and lower hot plate to move toward one another, and closes up upper and lower mould；Again by the injection port of upper mold upper end to mould type intracavitary administration
Raw material；After raw material curing, injection connects angle machine and controls upper and lower hot plate to separate upper and lower mould backwards to moving, manually take middle mould away
Plate and core, take out product from core.
Its existing shortcoming is：1st, the product that existing mould suppresses, need to be by follow-up not comprising buckle
Process inlays buckle (effect of buckle is that peace is buckled on car door, makes product be fixed with car door), and production cost is higher, easily occurs
The problem of neglected loading is buckled.Need to be removed the middle template in lower die with hand when the 2nd, molding, then core is removed with hand, by core
Interior product takes out, its is cumbersome, inefficiency.3rd, need to put back to artificial core into the card slot in lower die after taking out product
Card slot that is interior, easily colliding with lower die, causes mould easy to wear, shortens die life.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, and provide a kind of weather strip for automobile injection that built-in can be buckled
Connect angle mould.The interiors of products that it is suppressed is inlaid with buckle, reduces the manpower and cost of later process, improves production effect
Rate, reduces buckle neglected loading quality problems, makes product appearance more smooth, wheel hub is apparent.
The technical scheme is that：The weather strip for automobile injection that built-in can be buckled connects angle mould, including lower die, core, cunning
Plate and upper mold；Lower die is equipped with the groove A to match with core；Upper mold is equipped with the groove B to match with core；Core activity
In the groove A for installing lower die；Slide plate is movably arranged in lower die；Upper mold is movably arranged on above core；When upper mold and core lid
During conjunction, upper die and lower die, slide plate and core coordinate, and form the cavity for accommodating sealing strip；Lower die is equipped with positioning baffle and determines
Position column C；When upper mold and core cover, positioning baffle and positioning column C are respectively positioned in cavity.
Further technical solution is the present invention：Lower die is equipped with and the matched sliding slot A of slide plate；Slide plate is set on lower face
There is strip bulge；When slide plate is installed in lower die, the strip bulge on its lower face is fallen into the sliding slot A of lower die.
Further technical solution is the present invention：Bearing support B is fixed in lower die, and positioned at the mobile route of rack
On, to limit the stroke distances of rack.
Technical solution of the invention further is：Positioning column A is equipped with the center of upper mold lower end, upper mold lower end four corners are set
There are positioning column B and positioning column D, core is equipped with the location hole to match with positioning column A, is equipped with and positioning column B at Core edge
The notch to match, slide plate edge are equipped with the pit to match with positioning column D.
Technical solution of the invention further is：Lower die is equipped with sliding slot B；It further includes die opening mechanism；Die opening mechanism
It is located in lower die, and is associated with core, core is combined or separated with lower die under the driving of die opening mechanism；Die opening mechanism includes turning
Axis A, gear, operation lever, draw runner, rack, bearing support A, roller, stick up block, bearing support B and shaft B；Shaft A is vertically installed at down
On mould；Gear is installed on shaft A；Operation lever is fixed on gear；Draw runner is movably arranged in the sliding slot B of lower die；Rack is consolidated
It is connected on draw runner and is engaged with gear；Bearing support A is fixed on draw runner；Roller is movably arranged on bearing support A, and with sticking up block rolling
Dynamic contact；Bearing support B is fixed in lower die；Shaft B is movably arranged on bearing support B；Stick up on block installation shaft B, stick up block and holding
Portion is affixed with core.
Technical solution of the invention further is：Rack has two, is respectively and fixedly installed to the both sides of draw runner；Gear has
Two, engaged respectively with two toothed racks.
The present invention has the following advantages that compared with prior art：
1st, the interiors of products that the present invention suppresses is inlaid with buckle, reduces the manpower and cost of later process, improves production
Efficiency, reduces buckle neglected loading quality problems, makes product appearance more smooth, wheel hub is apparent.Lower die is equipped with positioning baffle and determines
Position column C.Under die opening state, buckle is placed on positioning column, buckle side offsets with positioning baffle and realizes positioning.Molding
Backward type intracavitary administration liquid rubber, liquid rubber will be buckled it is fully wrapped around, after liquid rubber curing after, buckle be embedded in production
In product.
2nd, rack has two, is respectively and fixedly installed to the both sides of draw runner, and gear has two, is engaged respectively with two toothed racks.
During rotating operation bar, gear and the rack synchronous movement on both sides, compared to unilateral setting gear and rack, double-side band gear and rack
Structure driven it is more steady, draw runner move when be subject to driving force direction it is consistent with the direction that draw runner moves, will not uneven wear
Sliding slot B.
3rd, mold when worker with hand by slide plate backward (away from core direction) push away, be rotated further by operation lever can make core to
Upper rotation, and then separated with lower die, it then can easily remove product.After removing product, rotating backward operation lever makes core downward
Rotate, and then be bonded with lower die.Mold-break operations are simple and convenient, improve production efficiency, and during die sinking, core is not deposited with lower die
In phenomenon of colliding with, reduce the abrasion of mould, extend the service life of mould.
Below in conjunction with figure, the invention will be further described with embodiment.
