Instrument.The weight repetitive error of general common injection machine is 1% or so, and preferable machine can reach 0.8%, is precision less than 0.5%
Machine, is ultraprecise machine less than 0.3%, and the applicant is accomplished by using weight repetitive error in the production process of plastic clock shell to exist
0.8% or less injection machine, i.e., accurate injection machine.With regard to the precision performance assessment criteria of accurate injection machine, except above-mentioned weight weight
Outside multiple error, another is the temperature control precision of extrusion equipment, and the temperature control precision of extrusion equipment will be directly affected into
The quality of product product, if temperature is too high, plasticizing is just overweight, will result in plastics and seriously degrades, product band overlap, switchs to dun
There are the filamentary silver filaments of sun, spot and a line mark in color, the surface of plastics drag chain, and there is a bubble inside, and current extrusion device is in heating,
There can be heating dead angle in usual recipient and can not be heated, cause the heating effect of partial material uneven, can be further
Reduce the physical property of product.
The content of the invention
In order to overcome above mentioned problem, this new one kind that provides can heat uniform accurate injection-moulding device extrusion dress
Put.
To achieve the above object, the technical scheme of this new offer is：
A kind of accurate injection-moulding device extrusion device, including extruded tube, extruding screw is provided with the extruded tube,
Heater is provided with outside extruded tube；Described heater includes heat-conducting plate, and heat-conducting plate is coated on recipient outer barrel face, led
The lateral wall of hot plate is glued with hot-fluid layer；One end of described hot-fluid layer is provided with connecting hole, and the connecting hole is connected with hot-fluid layer,
Heating medium is provided with hot-fluid layer；Control valve is provided with the connecting hole；Heating is additionally provided with outside hot-fluid layer
Layer, zone of heating is set around hot-fluid layer, and some exothermal infrared bodies, the work of exothermal infrared body are provided with the zone of heating
Hot-fluid layer is faced with face.
One layer of reflecting layer is additionally provided with the outside of the zone of heating.
Flow-guiding channel is connected with the connecting hole, the flow-guiding channel is set through zone of heating and reflecting layer, described
Control valve be arranged on flow-guiding channel.
The outside of flow-guiding channel is provided with branch flow passage, the terminal of the branch flow passage is provided with draw-off pump.
Above-mentioned technical proposal is beneficial in that：
This it is new provide a kind of accurate injection-moulding device extrusion device, using outside extruded tube set hot-fluid layer and it is right
The exothermal infrared body that hot-fluid layer is heated, due to being provided with heating medium in hot-fluid layer, heating medium can be in hot-fluid
Arbitrarily moved in layer, in heating, exothermal infrared body is heated to the heating medium in hot-fluid layer, and heats medium in heat
Moved in fluid layer, so can realize the heating to heat-conducting plate, and can ensure that the temperature in all regions of heat-conducting plate is consistent, will not
In the presence of the uneven phenomenon of heating, it can be ensured that product surface is not in the filamentary silver filaments of sun, spot, line mark and bubble phenomenon, is carried
The performance of high product.
It is clearly and completely described below in conjunction with the accompanying drawing technical scheme new to this, it is clear that described implementation
Example is originally new a part of embodiment, rather than whole embodiments.Embodiment based on this in new, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belongs to this novel protected scope.
Brief description of the drawings
Fig. 1 is the structural representation of this new embodiment 1.
Embodiment
