Description
Technical field
The utility model is related to a kind of auto parts machineries, and in particular to a kind of automobile engine cover for injection molding latches.
Background technology
Automobile panel can be divided into external covering part, inner cover and skeleton covering three classes by function and position.It passes
The body outer skin of system mainly uses metallic plate, is made of punch forming.After punch forming, it is also necessary to pass through the processes such as welding
Complete final automobile panel.Above-mentioned complex manufacturing technology, production efficiency are relatively low, equipment and cost of labor are higher, automobile covers
Cover piece heavier mass.
With the popularization of energy-saving and emission-reduction theory, automotive light weight technology becomes focal point, in recent years, gradually appears using injection molding
Method production body accessories, such as inner plate of car door, instrument board, body bottom accessory, bumper, bonnet of forming etc..Generally
For, automobile engine cover is hinged side relative to the rear side in vehicle body direction, and front side is locking side；The cover board is close to hinged side
The both ends of lower surface are each provided with a hinged-support for being hinged with vehicle frame；The cover board is close to the lower surface for locking side
There are one be used for and the matched lock of tapered end on vehicle frame for middle part setting.It is also adopted using the lock in the bonnet of injection molding
With injection molding, its intensity is relatively low as a result, after being used for a long time, can cause to latch the phenomenon that being broken, so as to cause being molded into
The bonnet quality of type is bad, the problem of should not promoting.
Invention content
In view of the above shortcomings of the prior art, technical problem to be solved in the utility model is：Provided that a kind of strong
Degree height, good toughness, and the automobile engine cover for injection molding that can improve bonnet forming quality latches.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution：
A kind of automobile engine cover for injection molding latches, it includes pedestal and lock, and the lock is in inverted U-shaped
Shape, the pedestal and automobile engine cover integrated injection molding, which is characterized in that the built-in metal latched by a U-shaped
It manages and is wrapped in outer built-in metal pipe and bottom end and the integrally formed plastic outer layer of pedestal form；It is embedding that a metal is equipped in pedestal
The both ends of part, the built-in metal pipe are fixedly connected through pedestal upper end with the metal insert in pedestal.By using embedded gold
After the metal insert and metal tube that belong to material, the intensity of lock can greatly be improved so that latch under the influence of external force also not
The phenomenon that will appear fracture.And plastics and this mode of coated metal are used, not only so that entire lock is connect tightly with bonnet
It is close, meanwhile, it is also very beautiful.
Further, the high 3-5mm of the pedestal, sets that there are two for injection molding or fixing screws in the middle part of pedestal
Vertical through holes, and the rounded rectangle in section of pedestal.Through-hole set by the middle of the base is not only able to use screw the bottom of by
Seat is further fixed with cover board, and lock fixation is made, additionally it is possible in injection moulding process, be reduced stress influence, be made Forming Quality
More preferably.Meanwhile pedestal surrounding is designed as fillet, stress concentration when can also prevent from being molded improves the Forming Quality of pedestal.
Further, the spacing at left and right sides of the lock is sequentially increased from top to bottom, built-in metal pipe and bottom in lock
Metal insert in seat is fixed together by welding, and metal insert is rectangular, thickness 2-3mm.In this way, using welding
Mode connects and fixes built-in metal pipe and metal insert so that its connection type is very secured.
Compared with prior art, the automotive engine hood lock fastener for injection molding that the utility model obtains has following excellent
Point：
1, by using after lock is embedded in the metal insert and metal tube of metal material, lock can greatly be improved
Intensity so that the phenomenon that fracture will not be occurred by latching under the influence of external force.
2, the through-hole set by the middle of the base is not only able to, convenient for further fixing pedestal with cover board using screw, make lock
Detain fixation, additionally it is possible in injection moulding process, reduce stress influence, make Forming Quality more preferably.
Description of the drawings
Fig. 1 is the structure schematic diagram of automobile engine cover in embodiment；
Fig. 2 is the cross-sectional view latched in embodiment.
In figure：Automobile engine cover 1, pedestal 2, metal insert 21, vertical through holes 22, lock 3, built-in metal pipe 31, plastics

Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment：
As shown, the automobile engine cover provided in this embodiment for injection molding latches, it is mounted on automobile engine cover 1
The back side of side is locked, 1 back side of the automobile engine cover is equipped with more cross reinforcings, waling and oblique reinforcing rib,
The lock includes pedestal 2 and lock 3, and the lock 3 is in inverted U-shaped, and the pedestal 2 is noted with 1 one of automobile engine cover
It is moulded into type, multiple and 1 integrated injection molding of automobile engine cover reinforcing rib is surrounded by pedestal 2；The lock 3 is by one
U-shaped built-in metal pipe 31 and it is wrapped in outer built-in metal pipe 31 and bottom end and 2 integrally formed plastic outer layer 32 of pedestal
Composition is set in pedestal 2 there are one metal insert 21, the both ends of the built-in metal pipe 31 through 2 upper end of pedestal and with pedestal 2
Interior metal insert 21 is by being welded and fixed.
Specifically, 2 high 3-5mm of above-mentioned pedestal, set that there are two for injection molding or fixing screws at the middle part of pedestal 2
