Technical field
The present invention relates to injection-moulding device field, related in particular to a kind of injection machine.
Background technology
Along with the development of industrial technology, high-end industrial production is come into people's life gradually, the life of the product of various designs
Producing and designing all needs through the several steps 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 of using while being some complex-shaped parts of batch production.Specifically refer to the material melting that is heated to inject die cavity by high pressure, after cooling curing, 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.Dynamic model and cover half closed formation running gate system and die cavity in the time of injection moulding, when die sinking, dynamic model separates to take out plastic products with cover half.
Although the structure of injection mold is due to the shape of plastics variety and performance, plastic products and structure and injector
Types etc. are different and possible ever-changing, 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 and the direct contact portion of plastics, and change with plastics and goods, are the most complicated in mold, change maximum, require processing fineness and the highest part of precision.Running gate system refers to the runner section of plastics from nozzle enters die cavity, comprises sprue, cold slug well, runner and cast gate etc.Forming part refers to the various parts that form article shape, comprises dynamic model, cover half and die cavity, core, curved lever and exhaust outlet etc.
Injection machine is that liquid material, thermoplastic or thermosetting material are made to various shape plastics by mould for plastics
The former of goods.In forming process, liquid material, thermoplastic or thermosetting material enter by the charge door of hopper in the injecting systems of injection machine, in hopper, carry out the manufacturing procedure before melting, mixing or other injection, injection machine applies high pressure to this type of material, makes its ejaculation be full of mold cavity in order to complete the process of injection moulding.Along with the needs of social development, the performance requirement of plastic products is also more and more higher, and for meeting the difference in functionality demand of various products, plastic products develop towards the line of production of multiple mixed materials from the single product of material.
In the prior art, various hybrid material are the mixing that complete material by charge door in hopper, in conventional art, hopper is to be completed and stirred and extruding material transfer work by screw rod, not only easily there is stirring unequal phenomenon being uniformly mixed in injection process, and the extruding material transfer of screw rod easily produces heat, cause the temperature of material to raise.Compound need keep low temperature just can guarantee that material keeps the state of material in when injection, once the temperature rise of material easily causes material partial status to change, mixing of materials unequal also reduces the performance of product after moulding.
Summary of the invention
The deficiency existing for prior art, object of the present invention is just to provide a kind of injection machine, and material is stirred, and guarantees the even of composition, has improved the quality of product.
To achieve these goals, the technical solution used in the present invention is such: a kind of injection machine, by body, fixed disc, upper rotary disk, stirring rod fixed bar, lower rotary disk, bearing pin, charging aperture, discharging opening, inject pipe material and channel-dividing device forms, the madial wall of described body is provided with heating wire, and is provided with temperature sensor in body; The bottom inside of described body is provided with rotating shaft, outside is installed with motor, and this motor is connected with rotating shaft; Described fixed disc is fixedly installed in rotating shaft outside, and the fixed disc center of circle overlaps with the axis of rotating shaft; The described upper rotary disk rotating around the axis, stirring rod fixed bar, the lower rotary disk rotating around the axis are fixedly installed on fixed disc successively by bearing pin; Described stirring rod fixed bar one end is positioned in the middle of rotary disk and lower rotary disk, the other end is installed with stirring rod; Described charging aperture is positioned at the top of body, and discharging opening is positioned at the bottom of body; Described one end that injects pipe material is connected with discharging opening, the other end is connected with channel-dividing device, and is provided with flowmeter; Described channel-dividing device comprises steering gear, servo-drive, servomotor and mould pipeline, and one end of described servomotor is connected with the steering gear that is arranged at injection moulding discharge nozzle, the other end is connected with driven by servomotor; Described mould pipeline is connected with injection moulding pipeline.
As a kind of preferred version, described stirring rod is two or more, and is uniformly distributed in the centre of upper rotary disk and lower rotary disk by stirring rod fixed bar.
As a kind of preferred version, described mould pipeline is two or more.
Compared with prior art, beneficial effect of the present invention:
