[specific embodiment]
Below in conjunction with accompanying drawing the present invention is done further detailed description of the process.
As shown in Figure 1, injection molding apparatus of the present invention comprises the injection machine modular system 1 of unblanking, in unblanking modular system 1, described injection machine is provided with injection mold 5, on described injection mold 5, be connected with and give the multi-functional die heater 2 of injection mold 5 heating, being provided with at described injection mold 5 one ends can be to the injection machine gun barrel 12 of described injection mold 5 injecting materials, on described injection machine gun barrel 12 1 ends, be connected with oven dry charging basket 6, in described injection machine gun barrel 12, be provided with and send being injection molding resin that the machine gun tube is heated into molten condition into the screw in injection molding machine 9 of injection mold 5, on described screw in injection molding machine 9 one ends, be respectively equipped with check ring 7 and check ring 8, on the injection machine gun barrel 12 between described check ring 7 and the check ring 8, be connected with gases at high pressure controller 3, be respectively equipped with gas check (non-return) valve 10 and gas check (non-return) valve 11 on two air shooters that between injection machine gun barrel 12 and gases at high pressure controller 3, are connected, on described injection machine gun barrel 12 nozzle front ends, be provided with the pipeline that is connected with gases at high pressure controller 3, stop and prevention contains the nozzle check (non-return) valve 14 that the molten condition resin 17 of nitrogen scintilla overflows under the gases at high pressure effect being provided with on the described pipeline, the described injection machine modular system 1 of unblanking, multi-functional die heater 2 and gases at high pressure controller 3 are by control terminal 15 controls.
Can be connected with nitrogen gas generator 4 or can pure nitrogen gas on the described gases at high pressure controller 3.
Preparation before the technology of the high light beam plastic of injection moulding metal of the present invention sense:
Preparation contains the resin of metal color and with its thorough oven dry; Place injection machine gun barrel 12 rear ends to allow the particulate resin of oven dry charging basket 6 be squeezed into the front end of screw in injection molding machine 9 screw in injection molding machine 9.
Set the parameter of multi-functional die heater 2, its hot water that produces 180 ℃ is heated the injection mold outer wall; Set the parameter of gases at high pressure controller 3, the amount of control nitrogen input injection machine gun barrel 12; Set the unblank condition of molding of modular system 1 of injection machine.
Technological process is described:
As shown in Figure 2, starting the injection machine modular system 1 of unblanking is in injection mold 5 to close the mould state, signal is transferred to control terminal 15 from the injection machine modular system 1 of unblanking, control terminal 15 is given multi-functional die heater 2 with signal feedback, multi-functional die heater 2 begins to injection mold 5 heating, start injection machine gun barrel 12, the particulate resins that contains metal color 16 to the fusing point intermediate value in the heating injection machine gun barrel 12 makes it become molten condition.
Reach the softening point setting value that is higher than resin itself when injection mold 5 actual temperatures, signal is transferred to control terminal 15, signal is transferred to gases at high pressure controller 3 again from control terminal 15, nozzle check (non-return) valve 14 is opened when gases at high pressure controller 3 received signals, gas check (non-return) valve 10 and gas check (non-return) valve 11 are closed, and the molten condition resin 17 that contains the nitrogen scintilla injects injection mold 5 rapidly under the promotion of screw in injection molding machine 9.
When the resin 17 that contains the nitrogen scintilla when molten condition is filled to the 80-95% of plastic rubber shaping product 13 gross weights in the injection mold 5, stops screw in injection molding machine 9 and push ahead, nozzle check (non-return) valve 14 stops to cut out simultaneously at screw in injection molding machine 9.The extruding of expanding rapidly of nitrogen scintillas is uniformly distributed in each corner in the die cavity with resin 17 promotions of molten condition in the middle of the plastic rubber shaping product 13 of this moment in the injection mold 5, the molten condition resin do not transfer to solid-state before, the miniature molecule of nitrogen is constantly expanding till the resin solidification of molten condition between the molecular resin, when the plastic rubber shaping product 13 in the injection mold 5 begin full gradually under the expansion of nitrogen scintilla, in the middle of whole plastic cement products forming process, do not have from the screw rod dwell pressure, product never is full of under the die cavity situation expansion by nitrogen molecule to be made between the plastic cement molecule and continues to increase at interval, make plastic cement products full, originally concentrated on the black vestige of metal strip of back, position, hole and strip difference color and also disperse and disappear, finally obtained can't see the plastic rubber shaping product on the high light metal sense of having of metal strip vestige and strip difference color surface along with the plastic cement molecule constantly expands.
When screw in injection molding machine 9 begins metering for preparation of following one-period storing, control terminal 15 receives the signal of gases at high pressure controller 3, control the softening point setting value that multi-functional die heater 2 begins to be lower than up to the temperature of plastic rubber shaping product 13 to injection mold 5 coolings resin itself, control terminal 15 acknowledge(ment) signals also feed back to injection machine 1, injection machine 1 die sinking, take out plastic rubber shaping product 13, i.e. high light plasthetics, an injection cycle end with metal sense.
Screw in injection molding machine 9 beginnings are when the rotation metering of injection machine gun barrel 12 rear ends, the particulate resins 16 of oven dry charging basket 6 the insides will be by the front end extruding of screw rod rotation toward screw rod, gas check (non-return) valve 10 and gas check (non-return) valve 11 are opened, nitrogen is exported from nitrogen gas generator 4 through gases at high pressure controller 3 and is injected in the injection machine gun barrels 12 foremost, the effect of check ring 7 and check ring 8 is when nitrogen injects, and avoids nitrogen molecule to leak into the middle rear end of the nozzle front end and the gun barrel of injection machine gun barrel 12.
