Abstract
The utility model relates to a quick cooling mould core of a light guide plate forming mould, which comprises a dynamic mould core and a static mould core, wherein the dynamic mould core and the static mould core are respectively arranged in a dynamic mould assembly and a static mould assembly. The dynamic mould core and the static mould core are respectively formed by sequentially laminating a first steel layer, a middle beryllium copper layer and a second steel layer, and at least one group of cooling pipelines are respectively arranged in the middle beryllium copper layers of the dynamic mould core and the static mould core. Compared with a full steel integral type mould core, the quick cooling mould core of the light guide plate forming mould can quickly absorb heat of the steel layers contacted with light guide plate sizing materials due to the fact the heat conduction of the middle beryllium copper layers is excellent, and quick cooling mould core utilizes the cooling pipelines in the middle beryllium copper layers to feed cooling water to quickly guide away the heat, so that the effect of quick cooling of the light guide plate sizing materials can be achieved, the forming cycle of the light guide plate is shortened, production efficiency is improved, and cost is reduced. Compared with a traditional mould, the quick cooling mould core of the light guide plate forming mould can shorten the forming cycle from original 8-10 seconds to 4-6 seconds.
Description
Technical field:
The utility model relates to LGP production mould technical field, refers in particular to a kind of die of the light guide plate forming mould that can cool off fast.
Background technology:
In the LGP injection molding process, after injection moulding was accomplished, needing a period of time to make the LGP sizing material cooling in the mold cavity was the complete moulding of LGP; And in mould, the cooling of the die that directly contacts with the LGP sizing material is the key of LGP molding cycle.Die in the existing mold (comprising dynamic model die and cover half die) all adopts all steel material integral design, and the main nature that relies on of its heat radiation cools off; It is slower to dispel the heat, so its time that needs is longer, causes the molding cycle of LGP longer; Production efficiency is not high, and cost is higher.
The utility model content:
The purpose of the utility model is to overcome the above-mentioned weak point of prior art, and a kind of die of the light guide plate forming mould that can cool off fast is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of die of the light guide plate forming mould that can cool off fast; Comprise the dynamic model die that is separately positioned in the dynamic model assembly and be arranged on the cover half die in the cover half assembly, wherein: said dynamic model die and cover half die are formed by stacking by the first steel layer, middle beryllium copper layer and the second steel layer respectively successively; And be respectively equipped with at least one group of cooling line in the middle beryllium copper layer of said dynamic model die and cover half die.
Between described first steel layer and the middle beryllium copper layer, be respectively equipped with public female fit structure between middle beryllium copper layer and the second steel layer.
Said cooling line is curved in middle beryllium copper layer.
Die adopts the first steel layer, middle beryllium copper layer and the second steel layer three-decker to be formed by stacking successively in the utility model, and both sides adopt steel can satisfy the wearability requirement of die; And compare with existing all steel monoblock type die; Because the heat conductivility of middle beryllium copper layer is splendid, the heat of the steel layer that the ability fast Absorption contacts with the LGP sizing material, and the cooling line in the beryllium copper layer feeds cooling water with the quick diversion of heat in the middle of utilizing; Make the LGP sizing material effect of cooling rapidly thereby reach; Shorten the molding cycle of LGP, enhance productivity, reduce cost.
Description of drawings:
The structural representation of Fig. 1 the utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1;
Fig. 3 is the planar structure sketch map of dynamic model assembly under the die opening state;
Fig. 4 is the planar structure sketch map of cover half assembly under the die opening state;
The specific embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
Like Fig. 1～shown in Figure 4; The die of the described light guide plate forming mould that can cool off fast of the utility model; Comprise the dynamic model die that is separately positioned in the dynamic model assembly 1 11 and be arranged on the cover half die 21 in the cover half assembly 2 that said dynamic model die 11 and cover half die 21 are formed by stacking by the first steel layer 301, middle beryllium copper layer 302 and the second steel layer 303 respectively successively; And be respectively equipped with at least one group of cooling line 304 in the middle beryllium copper layer 302 of said dynamic model die 11 and cover half die 21.
The utility model utilizes the splendid heat conductivility of beryllium copper, cooperates cooling line in the beryllium copper layer, and the radiating efficiency of whole die is significantly promoted, and both sides adopt steel can satisfy the wearability requirement of die; The second steel layer, 303 thinner thickness that contact with the LGP sizing material can be led LGP sizing material heat to middle beryllium copper layer 302 fast, accelerate the sizing material cooling forming.
In the utility model; Between described first steel layer 301 and the middle beryllium copper layer 302, be respectively equipped with public female fit structure 300 between middle beryllium copper layer 302 and the second steel layer 303; Present embodiment is to adopt the public female fit structure of dovetail grooved, and it not only can make the three, and directly the location is more accurate, helps the setting of cooling line; Contact area in the middle of also can increasing simultaneously between beryllium copper layer 302 and the first steel layer 301, the second steel layer 303, the lifting heat transference efficiency.
Like Fig. 3, shown in 4, said cooling line 304 is curved in middle beryllium copper layer 302.Cooling line 304 is the curved design in middle beryllium copper layer 302, can increase heat exchange area and heat exchange uniformity as far as possible, improves heat exchange efficiency, further quickens the die cooling.The entery and delivery port of cooling line is by passing in the first steel layer 301 and extend out, to the mould outside so that with extraneous pipeline connection.
In sum, the utility model is compared with existing all steel monoblock type die, because the heat conductivility of middle beryllium copper layer is splendid; The heat of the steel layer that the ability fast Absorption contacts with the LGP sizing material; And the cooling line in the beryllium copper layer feeds cooling water with the quick diversion of heat in the middle of utilizing, and makes the LGP sizing material effect of cooling rapidly thereby reach, and shortens the molding cycle of LGP; Enhance productivity, reduce cost.Compare with traditional moulds, adopt the utility model die structure, molding cycle can foreshorten to 4～6 seconds by original 8～10 seconds.
