Abstract
The utility model discloses an intramode injection-molding steel strap, which comprises the steel strap main body, both sides of the steel strap main body are respectively provided with a side wall vertically, the side wall is provided with a fin in an outward bending way. The utility model correspondingly provides an intramode injection-molding structure, which comprises a plastic outer shell provided with the intramode injection-molding steel strap. Therefore, the utility model has good bending resistance. Optimizedly, the fin is provide with a rubber-pulling hole, the weakening of the bending resistance of the injection-molding steel strap caused by the rubber-pulling hole designed at the side wall can be avoided. The utility model can effectively solve the problem of the deformation of parts of intramode injection-molding steel strap, thereby shortening the regulating-machine time, and the shaping process to the deformed parts can be avoided, therefore, the producing efficiency is greatly increased, and the production cost is saved.
Description
Technical field
The utility model relates to the mold injection field, relates in particular to a kind of in-mould injection and injection structure thereof.
Background technology
A kind of method of plastic products is made in injection moulding, utilizes pressure to annotate in the plastic products mould in the plastics of fusion, and cooling forming obtains wanting various working of plastics.
As depicted in figs. 1 and 2, the injection structure of existing electronic product generally includes plastic shell 1 and in-mould injection steel disc 2.General in-mould injection steel disc 2 has just carried out simple 90 degree bendings, for the part of in-mould injection steel disc 2, after the injection mo(u)lding, because the shrinkage factor of plastic cement is big big more a lot of than steel disc, therefore part can be to the many lateral bending songs of plastic cement, existing technical scheme has just been carried out simple 90 degree bendings to steel disc, because the thickness of the restriction steel disc in space generally has only about 0.4mm, simultaneously because the isostructural constraint of side button bit, the sidewall of 90 degree bendings is done not high, therefore its bending strength itself is just more weak, and the while peels off because of stressed in order to prevent steel disc and plastic cement, must open some holes on the sidewall of 90 degree bendings again, its bending strength is weakened once again, therefore the undercapacity of steel disc finally causes spares bend with the bending stress of opposing plastic cement, thereby influences the size of part, assembling and relevant fit clearance.As shown in Figure 3, after the moulding of steel disc in-mould injection, part can deform.
In summary, existing in-mould injection structure obviously exists inconvenience and defective, so be necessary to be improved on reality is used.
The utility model content
At above-mentioned defective, the purpose of this utility model is to provide a kind of in-mould injection steel disc and injection structure thereof, has bending strength preferably.
To achieve these goals, the utility model provides a kind of in-mould injection steel disc, comprises the steel disc body, it is characterized in that, the dual-side of described steel disc body vertically is provided with a sidewall respectively, and described each sidewall outwards bending is provided with a fin.
