Description

A kind of storage is penetrated transformational structure and has the injection-moulding device of this structure

Technical field

This utility model relates to injection machine field, is specifically related to a kind of storage and penetrates transformational structure and have the note of this structure Mould equipment.

Background technology

Carbon fiber is a kind of carbon content novel inorganic fibrous material more than 90% (mass fraction), has height Specific strength, high ratio modulus, high temperature resistant, corrosion-resistant, endurance, radioprotective, conduct electricity, conduct heat with relative A series of excellent properties such as density is little, belong to typical high-performance fiber.The existing material with carbon element of carbon fiber intrinsic Characteristic, has both again the soft machinability of textile fabric, and the component quality utilizing carbon fiber to make is light, ratio is firm Degree height, has wide range of applications.But, the most ripe carbon fiber application form mainly has four kinds, and one Planting and stick with paste laminate layer method for hands, lamination of being cultrated by the carbon fiber sheet after dipped glue is, or laying is while brush is climbed the tree Fat, hot repressing molding, the carbon fiber product intensity height that this kind of method is made, but production efficiency is low；A kind of For filament winding process, being wrapped in by carbon mono-filaments on carbon fiber axle, this kind of method is only applicable to make cylinder Body and holloware, and production efficiency is low；One is die pressing, and this method is by pre-soaked resin Carbon fibre material is put in metal die, makes unnecessary glue overflow after pressurization, then hot setting molding, The carbon fiber product intensity height that this kind of method is made, but same production efficiency is low, and structural member cannot be made； A kind of is long fine pellet injection moulding, by carbon fiber preprocessing, makes pellet, then via injection machine injection mo(u)lding, Although this kind of method solves production efficiency problem, but the carbon fiber that fibre length is longer in pellet, pass through Under screw in injection molding machine and the shearing of hot flow path and heat effect, in manufactured goods, fibre length is at more than 5mm only It is 30%, causes manufactured goods intensity to be substantially reduced.

Owing to the intensity of carbon fibre material itself at high temperature predisposes to damage, and the length of carbon fiber and its system Staggered complexity in finished product, will affect the intensity of its manufactured goods, it can be seen that, at present for carbon fiber Application, it is in sight that to ensure that carbon fibre material intensity realizes again the production technology of mass industrialized production be vacancy , the equipment of continuous prodution and processing and forming for realizing carbon fiber is similarly in the state of the market vacancy, Therefore, develop a kind of carbon fiber that i.e. can reduce can be increased again carbon fiber by the time of high temperature injury and making Length in product, and the equipment that can meet the efficiency requirements of industrialized mass is particularly necessary.

In prior art, the structure majority of injection machine uses the injection that helical screw agitator device combines with injection moulding apparatus Equipment, when using this equipment to produce moulding, helical screw agitator device both needs to stand after being melted by injected plastics material I.e. injecting, when mould pressurize, helical screw agitator device needs to quit work, and is otherwise in aqueous injection material Material will overflow injection machine, and this injection machine is the most inconvenient, and extremely inefficient, and repeatedly opens Stop equipment easily equipment to be caused damage.And in the prior art, have employed storage and penetrate the injection machine of transformational structure, When liquid injection molding material is stored temporarily, easily make the injected plastics material of fraction remain in storage and penetrate conversion The top of structure, in the course of time, old material can not get flowing out, and this part injection material is heating shape for a long time Under state, performance reduces, and will largely effect on the intensity of product after molding.

In view of drawbacks described above, this utility model creator obtains this reality finally through research for a long time and practice With novel.
