Abstract
The utility model discloses a kind of airbag cover injection molds, including dynamic model and cover half, the dynamic model and cover half form mold, there is the cavity being composed of dynamic model and cover half in the mold, the runner being connected to the cavity side is additionally provided in the mold, mould inscribe mechanism is provided in the runner, mould inscribe mechanism is fixed on cover half, and offers the glue-feeder being connected to runner in mould inscribe mechanism.After injection molding, extra material head is generated in glue-feeder, when mold molds, mould inscribe mechanism is motionless with cover half, when dynamic model retreats, product is moved with dynamic model, generates relative motion between such product and mould inscribe mechanism so that extra material head is cut, so there is no need to the extra material heads of artificial removal, production efficiency is improved, cost of labor is reduced, also improves the qualification rate of product.
Description
Technical field
The utility model belongs to injection mold technology, more particularly to a kind of airbag cover injection mold.
Background technology
With the improvement of people's safety consciousness, existing automobile is typically provided with air bag to protect driver and multiply
The safety of member, the air bag being more particularly set in vehicle steering wheel play an important role protection driver.Existing side
Solid nitrogen inflation is ignited to disk air bag generally use mechanical shock or electronic striking ignites the various types such as miniature gunpowder inflation
Formula, before inflation, air bag is hidden in steering wheel, and air bag is covered equipped with one piece of cover board on the steering wheel, works as vapour
Vehicle occur sharp impacts when air bag instantaneously inflate, cover board is torn and is popped up along certain tear line, be interposed between steering wheel with
Between driver, to play the role of protecting driver.
Airbag cover is typically to use injection molding, when injection molding using from mold side directly into glue, injection molding
Product side will produce extra material head afterwards, need the artificial extra material head part of removal by hand, to increase cost of labor,
But also production efficiency cannot improve, the disqualification rate of product appearance can be also improved.
Utility model content
For the above the deficiencies in the prior art, the purpose of this utility model is that a kind of airbag cover injection mold,
To improve the production efficiency of product, production cost is reduced, promotes product qualification rate.
In order to achieve the above objectives, the technical solution of the utility model is：
A kind of airbag cover injection mold, including dynamic model and cover half, the dynamic model and cover half form mold, described
There is the cavity being composed of dynamic model and cover half in mold, be additionally provided in the mold and be connected to the cavity side
Runner, mould inscribe mechanism is provided in the runner, mould inscribe mechanism is fixed in bulk on cover half, and
The glue-feeder being connected to runner is offered in mould inscribe mechanism.
Further, the glue-feeder is in closing in shape.
Further, the glue-feeder is trapezoidal.
The beneficial effects of the utility model are：
There is mould inscribe mechanism in the mold of the utility model, offered in mould inscribe mechanism be connected to runner into
Jiao Kou, when injection molding, glue enters runner from sprue, then flows into cavity, note from side using glue-feeder by runner
After being moulded into type, extra material head is generated in glue-feeder, when mold molds, mould inscribe mechanism is motionless with cover half, and dynamic model retreats
When, product is moved with dynamic model, and relative motion is generated between such product and mould inscribe mechanism so that and extra material head is cut,
So there is no need to the extra material heads of artificial removal, improve production efficiency, reduce cost of labor, also improve the conjunction of product
Lattice rate.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Attached drawing needed in description is briefly described, it should be apparent that, the accompanying drawings in the following description is only that this practicality is new
Wherein two width of type for those of ordinary skill in the art without having to pay creative labor, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the sectional view of the utility model.
Wherein, 1- products, 2- runners, 3- mould inscribes mechanism, 4- glue-feeders, 5- dynamic models.
Specific implementation mode
Below in conjunction with attached drawing, the technical solution in the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only the preferred embodiment of the utility model, instead of all the embodiments.Based in the utility model
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the range of the utility model protection.
Embodiment
As depicted in figs. 1 and 2, a kind of airbag cover injection mold, including dynamic model 5 and cover half, the dynamic model 5 and fixed
Mould forms mold, has the cavity being composed of dynamic model and cover half in the mold, is additionally provided in the mold
The runner 2 being connected to the cavity side is provided with mould inscribe mechanism 3 in the runner 2, and shown mould inscribe mechanism 3 is in
Bulk is fixed on cover half, and the glue-feeder 4 being connected to runner 2 is offered in mould inscribe mechanism 3.
When injection molding, glue enters runner 2 from sprue, then by runner 2 using glue-feeder 4 from side inflow type
Chamber after injection molding, generates extra material head in glue-feeder 4, and when mold molds, mould inscribe mechanism is motionless with cover half, moves
When mould 5 retreats, product 1 is moved with dynamic model 5, generates relative motion between such product 1 and mould inscribe mechanism 3 so that extra
Material head is cut, and so there is no need to the extra material heads of artificial removal, improve production efficiency, reduce cost of labor, also carry
The qualification rate of product is risen.
In the present embodiment, the glue-feeder 4 is in from outside to inside closing in shape, and the material head inner thickness formed in this way is thinner,
It is easier to cut extra material head in die sinking.
In the present embodiment, the glue-feeder 4 is trapezoidal, is also designed to the other shapes such as circle, ellipse certainly.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
