Abstract
The invention provides a television mold with a novel cooling system and a good cooling effect. The television mold comprises an upper mold base, a mold core, a lower mold base, a mold cavity, an injection molding port and the like. The upper mold base is provided with the mold core, and a spraying cooling chamber is arranged in the upper mold base. The bottom face of the spraying cooling chamber is composed by connecting crests and valley bottoms in sequence. Spray heads and a vacuumizing port are installed on the upper mold base, and the spray heads, the vacuumizing port and the spray cooling chamber are communicated. The lower mold base is provided with the mold cavity. A thermal insulating layer is arranged in the lower mold base at the lower end of the mold cavity. The lower mold base is internally provided with the injection molding port which is communicated with the mold cavity. According to the television mold with the novel cooling system, the upper mold base is internally provided with the spraying cooling chamber which is sprayed with mist and cooled through the spraying heads, and cold mist which is sprayed out downwards disperses towards the valley bottoms on the two sides through the crests, so that a melt body in the mold cavity is cooled more evenly and quickly.
Description
Technical field
The present invention relates to television set injection mold field, particularly relate to a kind of television set mould with novel cooling system.
Background technology
The injection mold of the injection mo(u)lding production of television set is mainly by dynamic model, cover half, cooling system forms, in the process of injection mo(u)lding, normally melt plastic cement material is injected mould from injection hole, when after the melt plastic cement condensation in die cavity, die sinking ejects plastic, cooling system can cool mould, shorten plastic cement setting time, thus improve the dimensional accuracy of product, Forming Quality and surface quality, the cooling system of current injection mold is all generally water cooling system, dispel the heat by arranging circulation waterway around mold cavity, but the cooldown rate of this type of cooling is slower, the flow velocity of branches different in circulating water pipe is different, make inhomogeneous cooling even, cooling effect is undesirable, and the impurity in the incrustation scale that produces of recirculated water and recirculated water can deposit blocking circulating water pipe, causes cooling system to lose efficacy, mould also can be caused to get rusty, the shortening mold use life-span, and molten plastic is being expelled in the process in die cavity, needing, heater is set die cavity is heated, avoid the melt solidifying entering die cavity, not only make the complex structure of mould, and cause the waste of the energy.
Summary of the invention
According to above technical problem, the invention provides a kind of television set mould with novel cooling system of good cooling results, comprise upper bolster, core, die shoe, die cavity, injection hole, it is characterized in that: also comprise spray cooling chamber, fog-spray nozzle, vacuum orifice, summit, the lowest point, thermal insulation layer, described upper bolster is provided with core, the inside of described upper bolster offers spray cooling chamber, the bottom surface of described spray cooling chamber is by summit, the lowest point connects and composes successively, described fog-spray nozzle, vacuum orifice is arranged on upper bolster, described fog-spray nozzle, vacuum orifice is communicated with spray cooling chamber, described die shoe offers die cavity, the inside of the die shoe of described die cavity lower end is provided with thermal insulation layer, the inside of described die shoe offers injection hole, described injection hole is communicated with die cavity.
Described fog-spray nozzle has N number of, N >=1, and described fog-spray nozzle is arranged on upper bolster corresponding to summit.
Described injection hole has N number of, N >=1.
Beneficial effect of the present invention is: the present invention improves on original injection mold, namely spray cooling chamber has been offered in the inside of upper bolster, the bottom of spray cooling chamber is set to the summit, the valley structure that connect successively, by fog-spray nozzle, misting cooling is carried out to spray cooling chamber, the cold mist of downward ejection is disperseed by the lowest point of summit to both sides, make the melt in die cavity carry out more evenly, fast cooling, improve cooling effect; And decrease the use of circulating water pipe, avoid because circulating water pipe blocks the situation causing cooling system to lose efficacy, extend the mold use life-span; Also add vacuum orifice, thermal insulation layer, spray cooling chamber can be evacuated by vacuum orifice, insulation is carried out to die cavity by the spray cooling chamber of vacuum and thermal insulation layer simultaneously and prevents melt solidifying, structure is simple, high insulating effect, thus improve the quality of plastic.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
According to Fig. 1, the present invention is further described:
As Fig. 1, upper bolster-1, core-2, die shoe-3, die cavity-4, injection hole-5, spray cooling chamber-6, fog-spray nozzle-7, vacuum orifice-8, summit-9, the lowest point-10, thermal insulation layer-11.
Embodiment 1
The present invention includes upper bolster 1, core 2, die shoe 3, die cavity 4, injection hole 5, spray cooling chamber 6, fog-spray nozzle 7, vacuum orifice 8, summit 9, the lowest point 10, thermal insulation layer 11, first core 2 and upper bolster 1 are wholely set during making, spray cooling chamber 6 is offered in the inside of upper bolster 1, by the underrun summit 9 of spray cooling chamber 6, the lowest point 10 connects and composes successively, then by fog-spray nozzle 7, vacuum orifice 8 is arranged on upper bolster 1, make fog-spray nozzle 7, vacuum orifice 8 is communicated with spray cooling chamber 6, die cavity 4 is offered again on die shoe 3, thermal insulation layer 11 is arranged on the inside of the die shoe 3 of die cavity 4 lower end, finally offer injection hole 5 in the inside of die shoe 3, injection hole 5 is communicated with die cavity 4.
Embodiment 2
During use, by upper bolster 1, die shoe 3 closes, make core 2, die cavity is formed between die cavity 4, by vacuum orifice 8, spray cooling chamber 6 is evacuated, then molten plastic is injected die cavity from injection hole 5, the spray cooling chamber 6 of vacuum and thermal insulation layer 11 carry out insulation to die cavity 4 simultaneously and prevent melt solidifying, after melt is full of die cavity 4, misting cooling is carried out by fog-spray nozzle 7 pairs of spray cooling chambers 6, the cold mist of downward ejection is disperseed by the lowest point 10 of summit 9 to both sides, Homogeneous cooling is carried out to the melt in die cavity, cool rear die sinking plastic is ejected, complete injection moulding work.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
