Abstract
The invention discloses a constant temperature heating injection molding machine. The constant temperature heating injection molding machine comprises a screw and a material cavity. The screw is arranged in the material cavity. The machine also comprises a heating cavity, which is coated outside the material cavity. A heat conduction liquid pipeline is arranged in the heating cavity, and constant temperature heat conduction liquid passes through the heat conduction liquid pipeline. Through the heating cavity arranged outside the material cavity and heating on the material by heat the conduction liquid in the heating cavity, the machine realizes a milder and more controllable heating mode.
Description
Technical field
The present invention relates to injection machine, relate in particular to a kind of heated at constant temperature injection machine.
Background technology
Injection machine heater is heating of plastic particle, make it reach molten state, and molten plastic is applied to high pressure, make its ejaculation and be full of mold cavity, can one-shot forming complex contour, size accurately or with the dense plastic products of the quality of metal insert, be widely used in the every field such as national defence, electromechanics, automobile, packing.The tubulose head of existing injection machine heater, by Resistant heating, preheating time that need to be very long, has been wasted electric energy greatly.Heat, to external environment transmission, makes production environment in the condition of high temperature, and workman's operating environment is severe.Head is exposed to easily oxidation in air, and resistance wire is in high-temperature oxydation state, and service life is short, need to often change, and the fluctuation of Resistant heating variations in temperature is large, and the control of temperature is meticulous not.
Summary of the invention
The invention provides a kind of injection machine of heated constant temperature gentleness.
For realizing above-mentioned design, the present invention by the following technical solutions:
An injection machine, comprises screw rod and material cavity, and described screw rod is arranged in described material cavity, also comprise heating chamber, described heating chamber is coated on outside described material cavity, is provided with conductive fluid pipeline in described heating chamber, in described conductive fluid pipeline, has constant temperature conductive fluid to flow through.
Wherein, described conductive fluid pipeline is a plurality of end to end U-shaped pipes, and described U-shaped pipe is along the axially-aligned of screw rod.
Wherein, described conductive fluid pipeline is the pipeline along material cavity periphery Spiral distribution.
Wherein, described heating chamber is outside equipped with vacuum chamber.
Wherein, in described vacuum chamber, scribble heat-reflective coating.
Wherein, described heat-reflective coating is aluminium lamination.
Wherein, described aluminium lamination is coated onto in vacuum chamber by plating.
Wherein, described heat-reflective coating is silver layer.
Wherein, described silver layer is coated onto in vacuum chamber by plating.
Wherein, described silver layer is coated onto in vacuum chamber by silver mirror reaction.
Beneficial effect of the present invention is: by heating chamber being set at material cavity outward, by conductive fluid mobile in heating chamber, to heating material, mode of heating is more gentle controlled.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of heated at constant temperature injection machine of the present invention.
Wherein: 1-screw rod; 2-material cavity; 3-heating chamber; 4-vacuum chamber.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.
Fig. 1 is the structural representation of a kind of heated at constant temperature injection machine of the present invention, as shown in the figure, this heated at constant temperature injection machine, comprise screw rod 1 and material cavity 2, described screw rod 1 is arranged in described material cavity 2, also comprises heating chamber 3, described heating chamber 3 coated with described material cavity 2 outside, in described heating chamber 3, be provided with conductive fluid pipeline, in described conductive fluid pipeline, have constant temperature conductive fluid to flow through.Described conductive fluid pipeline is a plurality of end to end U-shaped pipes, and described U-shaped pipe is along the axially-aligned of screw rod 1.Preferably, described conductive fluid pipeline is the pipeline along material cavity 2 periphery Spiral distributions.Described heating chamber 3 is outside equipped with vacuum chamber 4.In described vacuum chamber 4, scribble heat-reflective coating.Described heat-reflective coating is aluminium lamination.Described aluminium lamination is coated onto in vacuum chamber 4 by plating.Preferably, described heat-reflective coating is silver layer.Described silver layer is coated onto in vacuum chamber 4 by plating or silver mirror reaction.
By at material cavity, heating chamber being set outward, outside material cavity to conductive fluid heating, then by conductive fluid by the conductive fluid pipeline transmitting energy in heating chamber to heating material, mode of heating is more gentle controlled.A plurality of end to end U-shaped pipes can be complete coated by material cavity 2, realizes good heating effect, and can be from the turnover of same one end.The pipeline of Spiral distribution can evenly heat whole material cavity 2.In order to prevent that better heat is to external radiation, at the outer vacuum chamber that arranges of heating chamber 3, at the interior painting heat-reflective coating of vacuum chamber 3, can further prevent that energy is to external radiation, guarantee that injection machine has good working environment outward, and save the energy.
The above; be only the preferably specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any people who is familiar with this technology is in the disclosed technical scope of the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
