The heating device is arranged in the screw rod and the vacuum cavity is arranged outside the material cavity, so that energy waste in an energy transfer process is reduced by an inner-heating way; and the vacuum cavity is arranged to reduce thermal radiation, so that temperature in the material cavity is stable and energy resources are saved.
Description
Technical field
The present invention relates to injection machine, relate in particular to a kind of screw rod heating injection machine.
Background technology
The injection machine heater is the 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 plastic products dense accurately or with 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 the 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 the high-temperature oxydation state, and service life is short, need to often change.
Summary of the invention
The invention provides a kind of by the injection machine of conductive fluid heated at constant temperature.
For realizing above-mentioned design, the present invention by the following technical solutions:
A kind of screw rod heating injection machine, comprise screw rod and material cavity, and described screw rod is arranged in described material cavity, also comprises heater and vacuum chamber, and described heater is arranged at the inside of described screw rod, and vacuum chamber is arranged at the outside of described material cavity.
Wherein, described heater is heating wire.
Wherein, described heater is coil, and described coil is by the heating of electromagnetic induction drive screw.
Wherein, described heater is the conductive fluid pipeline, and conductive fluid is carried heat energy by described conductive fluid pipeline heating screw rod.
Wherein, the outer wall of described screw rod is provided with temperature sensor and obtains the temperature in material cavity.
Wherein, the inwall of described material cavity is provided with temperature sensor and obtains the temperature in material cavity.
Wherein, scribble heat-reflective coating in described vacuum chamber.
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 heater is set in screw rod, vacuum chamber is set outside material cavity, and the mode by interior heating reduces the energy dissipation in energy transfer process, by vacuum chamber is set, reduces heat radiation, keep the temperature stabilization in material cavity, save the energy.
The accompanying drawing explanation
Fig. 1 is the structural representation that a kind of screw rod heating of the present invention injection machine is housed.
Wherein: the 1-screw rod; The 2-material cavity; The 3-vacuum chamber.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Fig. 1 is the structural representation of a kind of screw rod heating of the present invention injection machine.As shown in the figure, this screw rod heating injection machine, comprise screw rod 1 and material cavity 2, described screw rod 1 is arranged in described material cavity 2, also comprise heater and vacuum chamber 3, described heater is arranged at the inside of described screw rod 1, and vacuum chamber 3 is arranged at the outside of described material cavity 2.Described heater is heating wire.The outer wall of described screw rod 1 is provided with temperature sensor and obtains the temperature in material cavity 2.The inwall of described material cavity 2 is provided with temperature sensor and obtains the temperature in material cavity 2.Scribble heat-reflective coating in described vacuum chamber 3.Described heat-reflective coating is silver layer.Described silver layer is coated onto in vacuum chamber 3 by plating.Preferably, described silver layer is coated onto in vacuum chamber 3 by silver mirror reaction.
Heater is arranged to the inside of described screw rod 1, is equivalent to directly in the inside of material cavity 2, material be heated, to the energy minimizing of external diffusion, the vacuum chamber 3 of material cavity 2 outsides can effectively reduce the radiation of heat, puies forward high-octane utilization rate.The heating wire of usining is lower as the heater cost.In order further to control the temperature in material cavity 2, outer wall set temperature sensor at screw rod 1 obtains the temperature in material cavity 2, for the variation of overall monitor temperature, at the inwall of material cavity 2 also set temperature sensor, guarantee that the temperature of material is in most suitable scope.In order further to improve automaticity and the levels of precision of producing, temperature sensor is connected with the power supply control apparatus of heater, when temperature changes, directly by the variation of electric current, control temperature.At the interior painting reflectance coating of vacuum chamber 3, reduce the radiation of energy, be preferably silver layer, it is plating or silver mirror reaction that silver layer is coated onto in vacuum chamber 3 to preferably mode.
Preferably, described heater is coil, and described coil is by the heating of electromagnetic induction drive screw.
The variation of electromagnetic induction heating temperature is more gentle, and controllable degree is higher.
Preferably, described heater is the conductive fluid pipeline, and conductive fluid is carried heat energy by described conductive fluid pipeline heating screw rod.
Conductive fluid heating is to deliver in the conductive fluid conduit after conductive fluid is heated to suitable temperature material cavity 2 is interior, and conductive fluid flows through the conductive fluid conduit, to being heated in material cavity 2, more easily keeps stationary temperature.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, anyly is familiar with the people of this technology 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.
