A kind of injection machine that can stir
Technical field
Injection-moulding device field, a kind of injection machine that can stir are the present invention relates to.
Background technology
Along with the development of industrial technology, high-end commercial production gradually comes into the life of people, and the production of the product of various designs and design are required for through the several step of layout design, mould shape and the manufacturing.Injection mold is one of most widely used mould in current industrial production, a kind of processing method used when being and produce some complex-shaped parts in batches.Refer specifically to by high pressure, the material melted that is heated is injected die cavity, after cooled solidification, obtain formed products.Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model constitutes running gate system and die cavity with cover half Guan Bi, and during die sinking, dynamic model separates with cover half to take out plastic.
Although the structure of injection mold may be ever-changing owing to the type etc. of plastics variety and performance, the shape of plastic and structure and injector is different, but basic structure is consistent.Mould is mainly made up of running gate system, thermoregulating system, forming part and constitutional detail.Wherein running gate system and forming part are contact portions direct with plastics, and change with plastics and goods, are the most complicated in mold, change maximum, it is desirable to processing fineness and the highest part of precision.Running gate system refers to that plastics enter the runner section before die cavity from nozzle, including sprue, cold slug well, sub-runner and cast gate etc..Forming part refers to constitute the various parts of article shape, including dynamic model, cover half and die cavity, core, curved lever and air vent etc..
Injection machine is that by mould for plastics, liquid material, thermoplastic or thermosetting material are made the former of variously-shaped plastic.In forming process, liquid material, thermoplastic or thermosetting material enter in the injecting systems of injection machine by the charge door of hopper, hopper carried out melt, mix or manufacturing procedure before other injection, injection machine applies high pressure to this type of material so that it is injection is full of mold cavity in order to complete the process of injection.Along with the needs of social development, the performance requirement of plastic is more and more higher, and for meeting the difference in functionality demand of various product, plastic develops from the single product of material towards the line of production of multiple mixed materials.
In the prior art, various hybrid material are the mixing being completed material by charge door in hopper, in conventional art, hopper is to complete stirring and extruding material transfer work by screw rod, the phenomenon that stirring is unequal not only easily occurs during stirring hybrid injection, and the extruding material transfer of screw rod easily produces heat, the temperature of material is caused to raise.Compound need to keep low temperature just to can ensure that the state of material holding material when injecting, and once the temperature of material rises, and easily causes the change of material parts state, the performance of product after the unequal also reduction molding of material mixing.
