Abstract
The utility model relates to a grid structure for an automobile. The grid structure for the automobile comprises a grid body, wherein fillets and protruding columns for installation are arranged on the grid body, and axial installing holes are formed in the protruding columns. The grid structure for the automobile is characterized in that grooves which correspond to the fillets are formed in the reverse side of the grid body. Compared with the prior art, due to the fact that the grooves are used for moderately reducing the wall thickness of the connecting portions between the fillets and the grid body, namely, the wall thickness is partially eliminated through adjustment of the structure of the reverse side of a product to effectively prevent sink marks from generating on the appearance surface, the forming quality of the appearance surface can be ensured; in addition, due to the fact that protruding ribs are added, good support is provided for bright strips, even when the bright strips are impacted by external force, collapse cannot easily happen, and the performance of the appearance surface of a post-installation finished automobile can be further improved; furthermore, due to the fact that the structure of each installing hole is improved, the purpose of preventing hands from being scratched and the purpose of improving strength of dies are achieved.
Description
Technical field
The utility model relates to a kind of car accessories, specifically refers to the grid that a kind of automobile is used.
Background technology
Grille for automobile is arranged on headstock part, is a kind of Plastic Parts, and oad is large, shape is comparatively special, and bright wisp (or claim upholstery border) also is installed on its front, playing decoration function, number is the structure disclosed in CN202294595 as the Chinese patent Granted publication.
In order to improve the intensity of grid, generally be provided with rib on grill body, this makes the wall thickness of connecting portion of rib and grill body blocked up, in injection machine, when the resin melten gel transfers solid to, the blocked up place of wall thickness volumetric shrinkage is slow, forms tensile stress, if product surface hardness is inadequate, and glue-free replenishing, product surface is just drawn sunken by stress, thereby produces the shrink trace on the surface of product, can't guarantee the appearance quality of product.Secondly, after bright wisp is arranged on grid, do not support because the back has corresponding structure, easily occur under external impacts subsiding being subject to, and then can't guarantee the appearance property of car load.moreover, be provided with the erection column that matches with thread-forming screw that use is installed on grill body, the structure of this erection column, mostly adopt at present structure as shown in figure 11, be that the mounting hole degree of depth on erection column is darker, the aperture is less, during injection moulding, must have the pin or the ejector sleeve structure that match with it on dynamic model, make on mould with elongated steel structure, such structure, easily scratch on the one hand operator's hand in the course of processing, can cause the undercapacity of mould on the other hand, when product carries out volume production, mould comes repercussion inside injection machine, elongated steel structure easily ruptures, finally affect the mold use life-span.
The utility model content
Technical problem to be solved in the utility model is the present situation for prior art, and a kind of automobile cell sructure that can guarantee the appearance quality is provided.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of automobile cell sructure, comprise grill body, be provided with rib and the projection of use is installed on grill body, have axial mounting hole in described projection, it is characterized in that: have groove on the grill body back side of corresponding described rib.
As further improvement of the utility model, the front of described grill body be interval with for bright wisp against convex tendon, like this when bright wisp is subject to external impacts, difficult subsiding.
In above-mentioned each scheme, described mounting hole can be designed to stepped hole, the contiguous described grill body in the hole, large footpath in this stepped hole, and through described grill body.During injection moulding, can by the shorter pin of mould outshot combination of monoblock, just can effectively prevent easily to scratch in the course of processing defective of hand, and can improve the intensity of mould.
In such scheme, the middle part in described mounting hole also can be provided with a baffle plate and this mounting hole is separated into upper mounting hole and lower mounting hole, and, the contiguous described grill body of described upper mounting hole and through described grill body.Like this by two pins that structure is shorter, can reach equally and prevent the purpose that scratches hand and can improve mould strength, and because pin is shorter, mould strength is high, thereby can further extend the mold use life-span.
Compared with prior art, because the utility model can utilize groove, suitably reduce the wall thickness of the connecting portion of rib and grill body, namely pass through the adjustment of product back structures, the local wall thickness of eliminating, effectively prevent the generation of appearance shrink mark, thereby can guarantee the Forming Quality of appearance.Secondly, by setting up convex tendon, give bright wisp with good support, even bright wisp is subject to the impact of external force like this, also can not subside easily, can further improve the car load appearance performance after assembling.

The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
To shown in Figure 10, this automobile comprises grill body 1 with cell sructure as Fig. 1, is provided with rib 2 and the projection 3 of use is installed on grill body, has axial mounting hole 4 in projection 3, to having groove 5 on grill body 1 back side that should rib.
The front of described grill body 1 be interval with for bright wisp 7 against convex tendon 6.
In the present embodiment, the mounting hole in projection 3 is designed to stepped hole, sees also Fig. 9, the contiguous grill body 1 of the large footpath hole 4a in this stepped hole, and through grill body 1.
Mounting hole in projection 3 is except being designed to said structure, can also adopt following structure, see also Figure 10, namely the middle part in this mounting hole is provided with a baffle plate 8 and this mounting hole is separated into upper mounting hole 4b and lower mounting hole 4c, and, the contiguous grill body 1 of upper mounting hole 4b and through 1 grill body 1.
