Abstract
The utility model discloses a structure for preventing pulling depression of flexible glue appearance. The structure is used for forming overmolding products. The inner side of the product is a non-appearance surface, the structure for preventing pulling depression of flexible glue appearance comprises ebonite comprising an ebonite body and a plurality of material overflow grooves formed from the surface of the ebonite body towards the ebonite body, wherein the material overflow grooves are located on the non-appearance surface on the inner side of the product; flexible glue comprising a flexible glue body and extension parts convexly extending from the surface of the flexible glue body; and the surface of the flexible glue body is in contact with the surface of the ebonite body, the extension parts are cooperatively inserted in the material overflow grooves, and the glue feed points of the flexible glue are located at the lower ends of the extension parts. The structure for preventing pulling depression of flexible glue appearance provided by the utility model is suitable for non-appearance elements on the inner side of the product, simple in structure, convenient to use and capable of well avoiding the pulling depression phenomenon of the product appearance.
Description
[technical field]
The utility model relates to a kind of injection structure, is specifically related to a kind of flexible glue outward appearance that prevents and draws sunk structure.
[background technology]
The quadric injection mould of flexible glue (referring generally to thermoplastic elastomer (TPE)) and ebonite (referring generally to thermoplastic) not only can make the surface of some products be full of soft feeling, can also increase attractive in appearance, the functional and added value of product.See also Fig. 1 and Fig. 2 illustrates, product 10 comprises ebonite 11 and is molded over flexible glue 12 on the ebonite 11, general flexible glue 12 advance glue point 13 all be placed on flexible glue 12 under, owing to be that ox horn advances glue, advance and have the strength of pullling mutually when glue point and product 10 come off, especially thermoplastic elastomer (TPE), deflection is big, and it is just bigger to pull power.When in moulding, the also incomplete cooling of flexible glue 12, the stub bar in a flash of die sinking will draw depression to flexible glue 12, thereby has had influence on the appearance of product 10, and then does not reach expected effect.
In view of this, be necessary to provide a kind of flexible glue outward appearance that prevents to draw sunk structure in fact, above-mentioned to solve because of the flexible glue deflection is big, produce the phenomenon that flexible glue draws depression.
[summary of the invention]
Therefore, the utility model provides a kind of flexible glue outward appearance that prevents to draw sunk structure, to solve the phenomenon of the easy-to-draw depression of flexible glue.
In order to achieve the above object, the flexible glue outward appearance that prevents that the utility model provides is drawn sunk structure, and it is applied to moulding double color mould product, and the inboard of this product is non-appearance, and this prevents that the flexible glue outward appearance from drawing sunk structure to comprise:
Ebonite, it comprises the ebonite body and offers some flash grooves from this ebonite body surface to this ebonite body;
Flexible glue, it comprises flexible glue body and the extension that protrudes out from this flexible glue body surface, and the surface of described flexible glue body contacts the surface of described ebonite body, and described extension cooperates in the described flash groove of insertion;
It is characterized in that described flash groove is positioned on the inboard non-appearance of described product, described flexible glue enters the lower end that the glue point is positioned at described extension.
Preferable, described flexible glue body and described extension are one.
Preferable, described flash groove is the groove that is surrounded by first contact-making surface, second contact-making surface and the 3rd contact-making surface, and described first contact-making surface is relative with described second contact-making surface, and described the 3rd contact-making surface connects described first contact-making surface and second contact-making surface.
Preferable, describedly prevent that the flexible glue outward appearance from drawing sunk structure is the notebook computer screen outer-border.
Compared to prior art, the utility model prevents that the flexible glue outward appearance from drawing sunk structure, offers flash groove by the non-appearance of penetrating the ebonite part at double color mould product first, and second when penetrating flexible glue, begin into glue in the lower end of described flash groove, thereby described flexible glue is incorporated in the flash groove.When die sinking, the ox horn stub bar be molded in the flash groove flexible glue and partly begin to break away from owing to advance the non-appearance of glue point, even draw depression also can not influence the outward appearance of product the flexible glue in the flash groove at product.
The flexible glue outward appearance that prevents of the present utility model draws sunk structure to be applicable to the inboard non-outward appearance part of product, and is simple in structure, easy to process, can well avoid product appearance to draw the phenomenon of depression.
[description of drawings]
Fig. 1 illustrates the perspective view into prior art products.
Fig. 2 illustrate into the A-A of Fig. 1 to cutaway view.
Fig. 3 illustrates to the utility model prevents outward appearance and draws the perspective view of sunk structure.
Fig. 4 illustrate into the B-B of Fig. 3 to cutaway view.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
See also Fig. 3 and Fig. 4 illustrates, the utility model prevents that the flexible glue outward appearance from drawing sunk structure, and it is applied to moulding double color mould product 100, and the inboard of this product 100 is non-appearance, this product 100 is the notebook computer housing, and this prevents that the flexible glue outward appearance from drawing sunk structure to comprise:
Ebonite 1, it comprises ebonite body 11 and offers some flash grooves 12 from the surface of this ebonite body 11 to this ebonite body 11, described flash groove 12 is positioned on the described product 100 inboard non-appearance, described flash groove is the groove that is surrounded by first contact-making surface 121, second contact-making surface 122 and the 3rd contact-making surface 123, described first contact-making surface 121 is relative with described second contact-making surface 122, and described the 3rd contact-making surface 123 connects described first contact-making surface 121 and second contact-making surface 122;
During double-color mold injecting products 100, first nozzle is injected cavity forming with ebonite 1, forms some flash grooves on the non-appearance of ebonite 1 corresponding product 100.After the die sinking first time, with matched moulds behind the mould Rotate 180 degree, advance in the glue at ox horn, will enter the lower end that glue point 23 is located at flash groove, second nozzle is injected flexible glue 2 in the die cavity by advancing glue point 23.During die sinking for the second time, ox horn stub bar 3 begins to break away from the flexible glue 2 that is molded in the described flash groove, owing to advance glue point 23 on the non-appearance of product 100, even draw depression also can not influence the outward appearance of product 100 flexible glue in the flash groove 2.
The flexible glue outward appearance that prevents of the present utility model draws sunk structure to be applicable to the inboard non-outward appearance part of product, and is simple in structure, easy to process, can well avoid product appearance to draw the phenomenon of depression.
Be pointed out that; the utility model is not limited to above-mentioned embodiment; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description based on technical solutions of the utility model all fall in the protection domain of the present utility model.
