Abstract
The utility model discloses an injection mold for cover plates of the steering wheel and the airbag of an automobile, which comprises a mold body. The center of the mold body is provided with a pouring area, one end of the mold body is provided with a main pouring port, the main pouring port is communicated with the pouring area, the mold body is also provided with two auxiliary pouring ports, and the two auxiliary pouring ports are communicated with the pouring area and are respectively arranged on two adjacent end faces of the end of the mold body with the main pouring port. Since the mold body is additionally provided with the auxiliary pouring ports, the flow distance of injection molding materials in the pouring area, in particular on tearing lines, is shortened, the condensation of the injection molding materials is effectively prevented, thus the product quality is guaranteed.
Description
Technical field
The utility model relates to a kind of automobile safety protector, specifically, relates to the cover plate injection mould of air bag in a kind of vehicle steering.
Background technology
Along with the raising of people's awareness of safety, existing automobile all is provided with the safety of air bag with protection driver and occupant usually, particularly is arranged on the air bag in the vehicle steering, and the protection driver is had important effect.Existing steering wheel air bag adopts mechanical shock to ignite the solid nitrogen inflation usually or electronic striking is ignited various types such as miniature gunpowder inflation; before inflation; air bag is hidden in the steering wheel; being provided with a cover plate on steering wheel covers air bag; the instantaneous inflation of air bag when automobile generation sharp impacts; cover plate is torn and ejected along certain tear line, every between steering wheel and driver, to play protection driver's effect.
The steering wheel airbag cover adopts injection mo(u)lding to be made usually, because the size of cover plate is less, existing injection mould adopts a cast gate to pour into a mould usually, as shown in Figure 1, usually the tear line on the steering wheel airbag cover is one I-shaped, during the instantaneous inflation of air bag, tear line from the center gradually to around tear, air bag ejects from breach.The thickness thinnest part at tear line place has only 0.4 millimeter, and in casting process, the flow resistance at the tear line place of cover plate is bigger, and flow velocity is slower, and shape is played gel easily, causes product quality to descend, even scraps.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of injection mould that carries out the cast of vehicle steering airbag cover, and it can not play gel the tear line place of cover plate shape.
For achieving the above object, the technical solution adopted in the utility model is: a kind of vehicle steering airbag cover injection mould, comprise mold, the center of described mold is a pouring area, one end of described mold is provided with main cast gate, described main cast gate and pouring area connect, and also are provided with dozzle on the described mold, and described dozzle and pouring area connect.
Described dozzle is two, is separately positioned on to establish on the mold on two adjacent end faces of main cast gate one end.
Adopt vehicle steering airbag cover injection mould of the present utility model, owing on mold, added dozzle, make injection molding material in pouring area, the distance that particularly flows on the tear line shortens, effectively prevent the gel of injection molding material, thereby guaranteed the quality of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-mold, 2-pouring area, 3-master's cast gate, 4-dozzle, 5-tear line.
The specific embodiment
As shown in Figure 1; the utility model discloses a kind of vehicle steering airbag cover injection mould; comprise mold 1; the center of described mold 1 is a pouring area 2, and an end of described mold 1 is provided with main cast gate 3, and described main cast gate 3 connects with pouring area 2; injection molding material flows into pouring area 2 by main cast gate 3; to finish cast to product, in sum, with existing vehicle steering airbag cover injection mould basically identical.
Innovative point of the present utility model mainly is also to be provided with dozzle 4 on the described mold 1, and described dozzle 4 connects with pouring area 2.When cover plate is poured into a mould, injection molding material also flows into pouring area 2 by dozzle 4 except flowing into the pouring area 2 by main cast gate 3, plays the effect of auxiliary cast, the length of the tear line 5 that injection molding material flows through is descended, prevent that injection molding material from gel taking place at tear line 5 places.During practical operation, adopt injection molding material to flow into pouring area 2 from main cast gate 3 earlier usually, and then flow into the order pouring type of pouring area 2 from dozzle 4.
Described dozzle 4 is two, is separately positioned on to establish on the mold 1 on two adjacent end faces of main cast gate 3 one ends.Dozzle 4 is set according to actual conditions with the distance of establishing the end face of main cast gate 3, to guarantee that injection molding material can gel.
