Abstract
The utility model provides an injection mold structure of a backlight source light guide plate. The injection mold structure comprises a main die, at least two main die cores, and a glue injection channel arranged on the main die, wherein the glue injection channel is communicated with the main die cores to mold the backlight source light guide plate; long sides of the main die cores are arranged oppositely; and the glue injection channel is arranged between the long sides of the main die cores. The injection mold structure has the beneficial effects that the injection length of the backlight source light guide plate is effectively shortened by a transverse arrangement mode, so as to solve the molding problem caused by an overlong product.
Description
Technical field
The utility model relates to a kind of mould structure for Mould Machining.
Background technology
Existing backlight source light conducting plate generally adopts injection molded, for obtaining higher production efficiency, the mould structure that is used for injection mo(u)lding, general correspondence arranges two core rods on the main mould, the general employing vertically of core rod arranged, and simultaneously two core rods carried out injection mo(u)lding by the glue injection channel between two core rods.Existing backlight source light conducting plate injection mold structure figure as shown in Figure 1.
Existing mould structure is 16: 9 product for ratio more than 3.5 cun, often because product length is longer, adopts this vertical arrangement mode product to be difficult to injection mo(u)lding.
The utility model content
The utility model is the shortcoming that overcomes above-mentioned existing mold structure, provides a kind of efficient higher backlight source light conducting plate injection mold structure.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of backlight source light conducting plate injection mold structure, comprise main mould, at least two main mould core rods and be arranged on glue injection channel on the main mould, described glue injection channel is communicated with described main mould core rod with the moulding backlight source light conducting plate, the long side of described main mould core rod is oppositely arranged, and described glue injection channel is arranged between the long side of described main mould core rod.
Preferably, described glue injection channel is communicated with described main mould core rod in the centre position of the long side of described main mould core rod.
Particularly, described main mould core rod is that mold insert combines.
The beneficial effects of the utility model are: adopt horizontal mode, effectively with the injection moulding contraction in length of backlight source light conducting plate, and then solve the difficult forming that causes owing to product is long.
Description of drawings
Fig. 1, existing backlight source light conducting plate injection mold structure figure.
Fig. 2, the backlight source light conducting plate injection mold structure figure of embodiment.
The specific embodiment
A kind of backlight source light conducting plate injection mold structure, its structure chart is referring to accompanying drawing 2, comprise main mould 1 and two main mould core rods 2 that are arranged on the main mould 1, main mould core rod 2 mold inserts combine, be formed at the core rod cavity of backlight source light conducting plate structural correspondence, the long side of two main mould core rods 2 is oppositely arranged, glue injection channel 3 is arranged between the long side of two main mould core rods, glue injection channel 3 is communicated with respectively with two main mould core rods 2 in the centre position of the long side of two main mould core rods 2, in order to moulding backlight source light conducting plate in the core rod cavity that plastic cement is injected main mould core rod 2 by glue injection channel 3.
With respect to the mould structure of existing vertical arrangement mode, present embodiment adopts horizontal mode, effectively with the injection moulding contraction in length of backlight source light conducting plate, and then solves the difficult forming that causes owing to product is long.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, it will be understood by those of skill in the art that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
