Description
Technical field
The utility model relates to a kind of heater, relates in particular to a kind of in-mold transfer printing injection molding Far-infrared Heating plate.
Background technology
In-mold transfer printing (In-Mold Decoration, IMD) injection mo(u)lding, high pressure when being heat when utilizing injection moulding of melt to arrive mould and locked mode, printed picture and text on diaphragm in advance are transferred on the plastic of moulding, make plastic in moulding, obtain a kind of modern surface decoration technique of decorating.Use this technology, need not again the moulding plastic is carried out conventional surface spraying, printing (moving silk, silk-screen, roll printing etc.), decoration technology such as gold stamping, the automaticity height, fraction defective is low, solvent-free volatilization, and picture and text are difficult for now being widely used in fields such as electronics, electrical equipment, household electrical appliances, automobile, as phone housing, Washing Machine Panel, automobile door panel, instrument and meter control panel etc. by scratch or mill flower.
Use the IMD technology, need in advance diaphragm to be transported between the punch and die of mould by film feeding machine location, treat diaphragm be compacted form confined space with die after, by vacuumizing, make diaphragm stretch, be fitted in the concave die cavity surface, carry out technologies such as matched moulds, injection moulding, pressurize, cooling afterwards again.Because quality problems such as the bearing bed of diaphragm is by Merlon (PC), polybutylene terephthalate (PBT) plastic sheetings such as (PET) formation, when normal temperature stretches, easily produces the stress whiting together with the picture and text layer, and is wrinkling; Particularly when the high-grade plastic to the distortion of some surface ratios, complexity carried out in-mold transfer printing, its diaphragm stretching depth often surpassed 20 millimeters, and this problem is particularly serious, and yield rate is almost nil.Along with complex-curved, high-grade picture and text plastic increasingly extensive in sector applications such as automobile, household electrical appliances, each injection moulding is decorated producer and is fallen over each other this bottleneck technology is studied.
Patent CN 1895906A has announced that a kind of wearing layer that is made of heat reactive resin compound and/or thermoplastification resin complexes by the substrate increase one deck at in-mold transfer thin membrane solves the method that in-mold transfer printing goods corner easily forms crackle; Patent CN201064936Y has announced a kind of by increase a press mold process of being finished by mold clamping force drive pressuring template mold insert in the matched moulds flow process, realizes dual press mold action, thereby reaches the wrinkle resistant purpose method of diaphragm; Patent CN102198721A has announced a kind of by design exhaust part in the steam vent of in-mold roller mould, divide stream, strengthen the air pressure absorption affinity and improve adsorption rate, thereby it is slower to solve the existing air-breathing speed of transfer printing injection mold, the easy fold of diaphragm and the susceptible to plugging method of steam vent; Patent CN201579900U has announced a kind of by the half-cylindrical projection of arch strip is set at the mold cavity stop portion, and diaphragm is easily broken by inhaling at the stop portion side of die cavity when producing, the method for cracking problem thereby overcome; Patent CN 101284413A has announced a kind of by gas circuit is set in punch, when being implemented in die and vacuumizing, to the blow method of heating pressurization of die cavity, solves the method for the big stretching depth of diaphragm and low-angle applying problem.
Patent CN 1895906A, CN201064936Y, CN102198721A, CN201579900U respectively by in diaphragm composition, press mold mode, vacuumize the innovation on mode and the mould structure, alleviated wrinkling, the problems of crack of common plastic in-mold transfer printing injection molding in varying degrees, the in-mold transfer printing complex-curved, high-grade plastic of diaphragm stretching depth above 20 millimeters whitens, wrinkling problem but can not solve.
Patent CN 101284413A can successfully address the above problem, but because the heatable substance that adopts is hot gas, the efficiency of heating surface is low, easily condensation, the temperature control difficulty is big, and because the use of relief valve in the patent, part hot gas can be trapped in the mold cavity, thereby easily produce calcination, water wave, bubble, problem such as wrinkling, so heater needs innovation.
