The invention combines the induction heating and the steam forming under the high temperature to effectively improve the combining lines on the surface of the product and reduces the production cycle.
Description
Technical field
The present invention relates to a kind of heater, relate in particular to a kind of heater that is applied in the make-up machine.
Background technology
In the mould of the injection molding product of tradition, generally use steam high-temperature molding technology with injection mo(u)lding.But because the restriction of mould structure itself and steam pressure, existing steam high-temperature molding technology increased relatively for the heating-up time of big mould, cause the production cycle greatly to prolong, and the product surface joint line after the moulding was more.
Summary of the invention
In view of the above problems, the invention provides a kind of heater of eddy-current heating coordinating with steam rapid heat cycle high-temperature molding,, reduce the purpose of production cycle to reach rapid raising mold temperature.
For achieving the above object, the present invention has adopted following technical scheme: a kind of heater of eddy-current heating coordinating with steam rapid heat cycle high-temperature molding, it is mainly used in the make-up machine, this device comprises a mould, a jet chimney and a heater coil at least, wherein, described mould is arranged on this make-up machine, in order to injection mo(u)lding; Again, this jet chimney is installed on this mould, and the heat that utilizes water steam to bring heats the mould inboard; Moreover, this heater coil is arranged on the manipulator that make-up machine is provided with, and this heater coil feeds the frequency conversion electric current and places the die cavity of mould by manipulator, the magnetic line of force that produces concentrates on the mould, because the induction effect of electromagnetism, produce vortex current, thereby make above-mentioned mould because the metal impedance of itself and by Fast Heating.
Preferable, the invention provides a kind of device of heater of eddy-current heating coordinating with steam rapid heat cycle high-temperature molding, wherein, described mould utilizes above-mentioned jet chimney, by the normal-temperature water or the water circulation of freezing water mould is lowered the temperature, again, also be provided with a temperature detector on this mould, in order to the detecting mold temperature.
Compared to prior art, the heater of a kind of eddy-current heating coordinating with steam rapid heat cycle high-temperature molding provided by the invention, this heater are mainly used in the injection moulding machine, make the mould mold temperature that raises fast to reach, and reduce the purpose of production cycle.
Description of drawings
Fig. 1 is a work schematic diagram of the present invention
The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Please refer to shown in Figure 1ly, the present invention is the heater of an eddy-current heating coordinating with steam rapid heat cycle high-temperature molding, and it is mainly used on the injection moulding machine, can improve mold temperature fast with injection mo(u)lding.
But described heater mainly comprises the mould 30 and of a control device 10, a heater coil 20, a jet chimney 40, a folding and is arranged at the temperature detector 50 on this mould 30.
Described temperature detector 50 is arranged on the mould 30, in order to detect the temperature of this mould 30, and issue a signal transmitted to control device 10, this heater coil 20 of control and jet chimney 40 heat mould 30 simultaneously behind these control device 10 these signals of reception, after treating that mould 30 is heated to a certain degree and carries out injection molding product, 40 pairs of moulds 30 of these control device 10 these jet chimneys of control are lowered the temperature, and subsequently, can die sinking take out product.
Wherein, described mould 30 is arranged on the make-up machine, this mould 30 by a patrix and once mould form, but this upper and lower mould is oppositely arranged and folding, and reserves a die cavity between this upper and lower mould, and this die cavity is used for the injection shaped article, moreover, a jet chimney 40 also is installed on this mould 30.
Again, described heater coil 20 is arranged on the manipulator of make-up machine, can stretch in the die cavity of above-mentioned mould 30 by manipulator, and die cavity is carried out eddy-current heating.
When make-up machine need heat action to mould 30, make-up machine issues a signal transmitted to control device 10, the manipulator of ordering this control device 10 to utilize make-up machine to be provided with extend into this heater coil 20 in the die cavity of mould 30 in order to shaped article, and this die cavity carried out Fast Heating, in addition, this control device 10 is controlled the intensification action that 40 pairs of moulds of jet chimney 30 carry out water steam simultaneously, and the heat that brings by water steam heats mould 30.Before this, the staff has set a upper and lower normal temperature value respectively according to the condition of injection mo(u)lding.
In present embodiment, this heater coil 20 feeds the frequency conversion electric current, the magnetic line of force that produces concentrates on the mould 30, because the induction effect of electromagnetism, produce vortex current, mould 30 then because of metal impedance itself by Fast Heating, so, heat up by above-mentioned eddy-current heating coordinating with steam rapid heat cycle, thereby reach the purpose of rapidly heating moulds.
When mould 30 is heated to a certain degree, after the temperature that temperature detector 50 on the mould 30 detects mould 30 reaches the last standard temperature value of setting, transmit signals to control device 10, by these control device 10 this heater coil 20 of control and jet chimneys 40, stop mould 30 is heated, subsequently, mould 30 begins matched moulds and die cavity is carried out injection to finish the injection mo(u)lding action.
After waiting to finish the injection molding product action, make-up machine returns a signal to this control device 10,40 pairs of moulds 30 of this jet chimney of control were lowered the temperature rapidly after this control device 10 received orders, the water circulation that this jet chimney 40 utilizes normal-temperature water or freezes water in the present embodiment is to take away the heat of mould 30, after mould 30 is cooled to down the standard temperature value, temperature detector 50 issues a signal transmitted to control device 10 after detecting the temperature of mould 30 again, and control device 10 control jet chimneys 40 stop mould 30 is carried out cooling water circulation, so, mould 30 can carry out the die sinking action, thereby the manipulator that utilizes make-up machine to be provided with takes out product in the die cavity of mould 30.
