Operation principle of the present utility model is as follows:
Change course according to mold temperature, a complete rapid thermal cycles injection molding cycle can be divided into mold heated stage, high temperature maintenance stage, mold cools down stage and low temperature and keep the stage.Be elaborated below in conjunction with the operation principle of above-mentioned several working stages to electrical heating rapid thermal circulation injection mould of the present utility model.
In the mold heated stage, attemperating unit is to the second cartridge heater 16 ' energising in the first cartridge heater 16 in the cavity plate 9 and the core plate 7, a large amount of Joule heats that the first cartridge heater 16 produces will constantly spread in cavity plate 9, a large amount of Joule heats that the second cartridge heater 16 ' produces will constantly spread in core plate 7, thus the temperature of rising mold cavity surface and whose surfaces.Because being the geometry conformal according to mold cavity surface and whose surfaces, the first cartridge heater 16 and the second cartridge heater 16 ' be evenly arranged, distance between cartridge heater 16 and the cavity surface, between cartridge heater 16 ' and the core plan is consistent, so the temperature of cavity surface and core plan obtains efficiently, evenly promotes in the heating process.In the mold heated process, be installed in the first thermocouple 6 real-time temperature to attemperating unit feedback mold cavity surface in the cavity plate 9, be installed in the second thermocouple 6 ' the real-time temperature to attemperating unit feedback-type wicking surface in the core plate 7, when temperature is increased to predefined temperature upper limit, attemperating unit cuts off the power supply of the first cartridge heater 16 and the second cartridge heater 16 ', thus the stopped heating mould.
Keep the stage at high temperature, the electrical heating rapid thermal circulation injection mould is in the matched moulds state, and the plastic melt in the injecting machine material tube will enter mold cavity through nozzle, main running channel 1, runner 13, cast gate 14 successively, until melt is full of die cavity fully.Because mould-filling time is very short, so the mold cavity temperature can maintain the state that heats after finishing substantially in this process.In this process, if the mold cavity drop in temperature is too much, attemperating unit can be again to the second cartridge heater 16 ' energising in the first cartridge heater 16 in the cavity plate 9 and the core plate 7, to keep the high mould temperature state of mold cavity so.
In the mold cools down stage, attemperating unit passes into low-temperature cooling water by the control reversal valve to the first cooling line 18 between cavity plate 9 and the cavity side coldplate 10 and the second cooling line 18 ' between core plate 7 and the core side coldplate 4, cooling water will constantly be taken away the heat in cavity plate 9 and the core plate 4 by heat convection, thereby cool off rapidly the plastic 8 between cavity plate 9 and core plate 4 and cavity plate 9 and the core plate 4.Because the first cooling line 18 between cavity plate 9 and the cavity side coldplate 10 and the second cooling line 18 ' between core plate 7 and the core side coldplate 4 evenly distribute according to the geometry conformal of mold cavity surface and whose surfaces respectively, the first cooling line 18 and cavity surface, the second cooling line 18 ' core plan apart from uniformity, so can guarantee efficient, the evenly cooling of plastic 8.In cooling procedure, be installed in the second thermocouple 6 ' in the first thermocouple 6 in the cavity plate 9 and the core plate 7 in real time to the temperature of attemperating unit feedback mold cavity surface and whose surfaces, when temperature is reduced to predefined lowest temperature, attemperating unit switches reversal valve and stops to pass into low-temperature cooling water in the first cooling line 18 and the second cooling line 18 ', thereby stops cooling die.
Keep the stage at low temperature, attemperating unit passes into gases at high pressure by the control reversal valve to the first cooling line 18 between cavity plate 9 and the cavity side coldplate 10 and the second cooling line 18 ' between core plate 7 and the core side coldplate 4, residual cooling water drainage in the first cooling line 18 and the second cooling line 18 ' is removed, thereby avoid the excessive descent of mold temperature, effectively avoid simultaneously cooling water residual in the first cooling line 18 and the second cooling line 18 ' to the interference of mold heated in the next molding cycle, be conducive to improve mold heated efficient.In this stage, the temperature of plastic 8 has been cooled to satisfy and has ejected requirement, therefore can open mould, takes out plastic 8, thereby finishes a rapid thermal cycles injection molding cycle.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
