The utility model relates to a kind of in-mold decoration heat pressing forming machines.
Background technology
In recent years, raising and science and technology development along with living standards of the people, requirement for incrustation also rises to a new class, so the current up-to-date surface decoration tech technology with IMD (" IMD " is the abbreviation of In-MoldDecoration, i.e. " in-mold decoration ") technical development has just been arranged.IMD puts into injection mould with the decoration sheet that prints forming, then with the back side of resin injection at formed sheet, make the be combined into one technology of curing molding of resin and sheet material, formed products integral body to stereo structure can be banded printing, makes product reach ornamental and functional effect.IMD technology is the first-selected technology that the control panel, button, shell, visual window lens, instrument board, nameplate of products such as present household electrical appliance, mobile phone, automobile etc. made, replacing traditional PVC card membrane process, its main feature is: corrosion-resistant, wear-resisting, chemical-resistant reagent in surface and cleaning agent, non-scale, do not come off, surface decoration effect is splendid.
The IMD technical process mainly comprises: film printing-film forming-film cutting-finished product injection moulding.Wherein the film forming process is that the printing plastic sheeting is carried out the 3 D stereo moulding by make-up machine.Existing heat pressing forming machines mainly is by the workbench heating element shaping mould to be carried out preheating earlier, high pressure matched moulds then, behind matched moulds, again shaping mould is heated, heat passes to film by shaping mould, make the moulding of film hot high pressure, this moulding process film before matched moulds does not soften to the heat distortion temperature HDT value of plastics, and its softening process carries out behind matched moulds, and this film forming technology easily makes the film of moulding frill.Chinese patent publication number CN1486829 for example, open day is on April 7th, 2004, the name of innovation and creation is called " a kind of in-mode inserts injection moulding (IMD) Mask Molding Machine " and discloses a kind of such film hot high pressure make-up machine, this make-up machine mainly comprises body, preheating table, heating plate, shaping mould, controller, hydraulic press, air compressor machine, feeder and sliding rail, and its weak point is: the bad thin-film sheet of draftability such as PET are carried out moulding occur gauffer easily; Adopt the pressure-air moulding, need configuration High Pressure Air Compressor in addition, production cost is higher; Adopt the oil pressure matched moulds, its mould-closing stroke needed for 3 times in second when 15cm, and the matched moulds time is longer, and efficient is lower.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, provide that a kind of production cost is lower, moulding in-mold decoration heat pressing forming machines fast, described in-mold decoration heat pressing forming machines carries out moulding to the bad thin-film sheet of draftability and is difficult for occurring gauffer.
The technical scheme that the utility model adopted is: the utility model comprises body, mould bases, heater, shaping mould, electric control gear, described mould bases, described heater, described electric control gear is arranged on the described body, described shaping mould is arranged on the described mould bases, it also comprises pneumohydraulic pressure-cylinder, described pneumohydraulic pressure-cylinder is arranged on described mould bases top, the adjacent setting on described organism soleplate of described mould bases and described heater, described heater comprises the heating plate cylinder, the heating plate guide groove, heating plate, the heating plate height adjustment mechanism, the heating plate case, described heating plate cylinder is arranged on the described heating plate case, described heating plate guide groove is arranged in the described heating plate case, described heating plate is slidingly connected mutually with described heating plate guide groove, and described heating plate height adjustment mechanism is connected with described heating plate case and is arranged on described heating plate case below.
The utility model also comprises assisted heating device, and described assisted heating device is arranged on described shaping mould relevant position.
Described electric control gear comprises Programmable Logic Controller.
The beneficial effects of the utility model are: because the utility model comprises pneumohydraulic pressure-cylinder, heating makes it reach the heat distortion temperature HDT value of plastics to thin-film sheet by heater, carry out mould assembling action and moulding by described pneumohydraulic pressure-cylinder then, without the pressure-air moulding, therefore do not need to dispose High Pressure Air Compressor in addition, so the utility model production cost is lower; Because the utility model carries out mould assembling action and moulding by described pneumohydraulic pressure-cylinder, pneumohydraulic pressure-cylinder at the F.F. stroke by the quick little power of compressed air-driven shaping mould near workpiece, its stroke only needed for 1 time in second when 15cm, reduce a lot of times in 3 seconds of required time of identical stroke than adopting pressure-air to be molded over, efficient improves, so the utility model moulding is quick; Because heating makes it reach the heat distortion temperature HDT value of plastics to the utility model to thin-film sheet by heater before matched moulds, its softening process carries out before matched moulds, not rigid stretching in the forming process, be difficult for occurring gauffer so the utility model carries out moulding to the bad thin-film sheet of draftability.
