Description

Notebook computer C shell injection moulds
Technical field
A kind of mould is the utility model is related to, more specifically, it relates to a kind of notebook computer C shell injection moulds.
Background technology
Notebook is generally made up of four main housings, is commonly called as in production as A shells, B shells, C shells and D shells, Wherein notebook C shells refer to cover on the main frame of notebook.
Computer notebook C shells are molded using IMR, i.e., a kind of forming method injected and molded, in order to save subsequent artefacts Material head cost is cut off, in forming process, forms die sinking using three template dies are poured in down a chimney, three diaphragm plates include fixed plate, stripper plate and male model Plate, traditional runner that pours is opened on pressing plate, and pressing plate is embedded to be used to the lower end of sprue bush being fixed on fixation in fixed plate On plate, the upper end of sprue bush is embedded in the die in male template.But pour in down a chimney three template dies and exist defective, the material head of cast is too Long, so as to cause molding cycle to extend, production efficiency reduces.In addition, traditional sprue bush material is SKD61, heat dispersion is poor.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of notebook computer C shells injection Mould, solve the problems, such as to pour into a mould the oversize reduction production efficiency of material head.
To achieve the above object, the utility model provides following technical scheme:
A kind of notebook computer C shell injection moulds, including male template, stripper plate, fixed plate, pressing plate and sprue bush, described Die is inlaid with male template, the sprue bush sequentially passes through fixed plate, male template and die from top to bottom, the sprue bush Upper end is embedded in the die, and lower end is embedded in the fixed plate, the lower surface of the fixed plate open up it is fluted, it is described Offered in groove and pour runner, this pours runner and turned on sprue bush, and the pressing plate is with setting the stripper plate thereunder to consolidate Fixed connection.
By using above-mentioned technical proposal, pouring runner and be opened on the groove of fixed plate, pressing plate is fixedly connected with stripper plate, Colloid can directly since in fixed plate pour runner feed, enter glue mode with traditional, that is, it is to be opened in pressing plate to pour runner On compare, by change pour runner position and sprue bush connected mode, material head length is shortened, so as to shorten cast The work period of production, improve production efficiency.
The utility model is further arranged to:The sprue bush material is beryllium copper.
By using above-mentioned technical proposal, beryllium copper perfect heat-dissipating and each good physical properties, it is possible to reduce moulding Cool time.
The utility model is further arranged to:The pressing plate is fixed with stripper plate by screw.
By using above-mentioned technical proposal, the connection of pressing plate and stripper plate is easy and effective, difficult for drop-off.
The utility model is further arranged to:The sprue bush is provided with two.
By using above-mentioned technical proposal, two sprue bush pour into a mould work simultaneously, while greatly improving cast efficiency, make Colloid is more evenly distributed in die, improves yield rate.

Embodiment
The utility model notebook computer C shell injection mould embodiments are described further referring to the drawings.
A kind of notebook computer C shell injection moulds, including male template 1, stripper plate 3, fixed plate 2, pressing plate 4 and sprue bush 5, Die 6 is inlaid with the male template 1, the sprue bush 5 sequentially passes through fixed plate 2, male template 1 and die 6, institute from top to bottom The upper end for stating sprue bush 5 is embedded in the die 6, and lower end is embedded in the fixed plate 2, the lower surface of the fixed plate 2 Open up fluted, offered in the groove and pour runner 21 for the colloid that circulates, this pours runner 21 and turned on sprue bush 5. The mid-length position for pouring runner 21 is provided with glue-feeder, and the both ends for pouring runner 21 turn on sprue bush 5 respectively, and colloid is from glue-feeder Into being trickled along runner 21 is poured to its both ends, sprue bush 5 is provided with two, pouring the both ends of runner 21 respectively, colloid passes through Sprue bush 5 injects die 6, and two sprue bush 5 pour into a mould work simultaneously, accelerate the duration of pouring of product, improving production efficiency.Tradition Casting moulds, that is, pour runner 21 and be opened on pressing plate 4, pressing plate 4 is embedded to be used for the lower end of sprue bush 5 in fixed plate 2 It is fixed in fixed plate 2, groove is provided with the lower surface of fixed plate 2, so the length of material head is thickness+fixed plate 2 of pressing plate 4 Thickness+fixed plate 2 to male template 1 distance+male template 1 thickness+die 6 thickness-depth of groove, be 200mm.And pass through Technological improvement is crossed, runner 21 is poured and is opened in fixed plate 2, pressing plate 4 is fixedly connected with stripper plate 3, so the length of material head is solid Thickness+fixed plate 2 of fixed board 2 arrives the depth of thickness-groove of thickness+die 6 of distance+male template 1 of male template 1, is 180mm, material head length shorten, and so as to shorten the work period of cast production, improve operating efficiency.
Traditional material of sprue bush 5 is SKD61, and heat dispersion is poor, because the colloid in molten condition will lead to always Cross sprue bush 5 and inject die cavity, and if heat dispersion is poor, colloid still keeps higher temperature during injection, the cooling needed for that Time also can be very long, and by technological improvement, the material of sprue bush 5 is changed into beryllium copper, the perfect heat-dissipating of beryllium copper and each physical Can be excellent, the material of sprue bush 5 is well suited as, for before, the glue temperature reduction of cast, is molded required cooling Time is also reduced, and is shortened the work period and is also just improved production efficiency.The pressing plate 4 is fixed with stripper plate 3 by screw to be connected Connect, the connection of pressing plate 4 and stripper plate 3 is easy and effective, difficult for drop-off.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
