Please coordinate with reference to shown in figure 7, the present invention is a kind of vacuum forming, and its step includes:
S1: put material, please coordinate with reference to shown in figure 2, the longitudinal lowering or hoisting gear 20 of lower heater is to make lower heater 22 rise one highly, low mold frame horizontal mobile device 21 is to make low mold frame 23 transverse shifting one distances, the longitudinal lowering or hoisting gear 24 of low mold frame also rises one highly, one workpiece 50 is that material placing hole 230, one films 51 that are placed in low mold frame 23 are located at low mold frame 23 top, and the size of film 51 is the sizes that are greater than material placing hole 230.
S2: press mold, please coordinate with reference to shown in figure 3, low mold frame horizontal mobile device 21 moves again, so that low mold frame 23 returns back to original position, the longitudinal lowering or hoisting gear 24 of low mold frame is the height that rise, it is to rise that the longitudinal lowering or hoisting gear 32 of upper molded plate coordinates the longitudinal lowering or hoisting gear 24 of low mold frame, and makes the longitudinal lowering or hoisting gear 32 of upper molded plate rise one highly.
The longitudinal lowering or hoisting gear 32 of upper molded plate is the height that decline, so that upper molded plate 31 combines with lower film frame 23, and makes upper molded plate 31 be pressed film 51, and make film 51, is a formation state.
S3: heating, please coordinate again with reference to shown in figure 3, low mold frame 23 edge is that clip is in fixed block 242, and make low mold frame 23 along with the longitudinal lowering or hoisting gear 24 of low mold frame rises, the longitudinal lowering or hoisting gear 20 of lower heater drops to original position, and low mold frame 23 and lower heater 22 are separated, and workpiece 50 is also separated with low mold frame 23.
Heater bracing frame horizontal mobile device 41 is that heater bracing frame 42 is moved towards low mold frame 23 directions along slide rail set 40, and make heater bracing frame 42 extend to low mold frame 23 bottom, heater 43 heats film 51 within a heat time, heat time is 15 seconds, and post-heater bracing frame horizontal mobile device 41 is that heater bracing frame 42 is moved towards the direction away from low mold frame 23, so that heater 43 leaves low mold frame 23 bottom.
S4: moulding, please coordinate with reference to shown in figure 4, the longitudinal lowering or hoisting gear 20 of lower heater is to continue to rise one highly towards upper die unit 3, so that low mold frame 23 combines with lower heater 22, and workpiece 50 is entered in material placing hole 230 once again, 24 of the longitudinal lowering or hoisting gears of low mold frame drop to original position, and the longitudinal lowering or hoisting gear 24 of low mold frame is separated with low mold frame 23.
The longitudinal lowering or hoisting gear 32 of upper molded plate coordinates the longitudinal lowering or hoisting gear 20 of lower heater to rise, and returns back to original position, and upper molded plate 31 is still maintained at bonding state with low mold frame 23.
When upper molded plate 31 is got back to original position, pump device of air 33 and be to provide a negative pressure to upper molded plate 31, negative pressure Shi Shi hole has a negative-pressure sucking, so that upper molded plate 31 is able to adsorbed film 51, meanwhile, air extractor is to provide a negative pressure to material placing hole 230 by negative pressure hole 231, and makes material placing hole 230 form a subnormal ambient, providing the time of negative pressure to be about 6 seconds, is to make film 51 more smooth and the object of negative pressure is provided.
The embossed pattern 312 of upper molded plate 31 is to make film 51 have pattern, and except the designed pattern of film 51 own, embossed pattern 312 artistic skills have different patterns in film 51, therefore can increase its aesthetic appearance of product.
Pump device of air 33 and be to provide a malleation to upper molded plate 31, and make mould plate 31 produce a malleation thrust, air extractor still provides negative pressure hole 231 1 negative pressure to material placing hole 230, so that material placing hole 230 is maintained at a subnormal ambient, rely on the pressure reduction of malleation and negative pressure, and make film 51 and workpiece 50, the two can mutually combine, after film 51 and workpiece 50 combinations, pump device of air 33 and stop providing malleation, air extractor stops providing negative pressure.
The longitudinal lowering or hoisting gear 24 of low mold frame drops to original position, to take out the workpiece 50 with film 51.
Comprehensive above-mentioned vacuum forming method of the present invention and device thereof, because upper molded plate 31 is a smooth plate body, therefore when upper molded plate 31 provides negative-pressure sucking to film 51, film 51 is subject to the restriction of upper molded plate 31, and make film 51 present a formation state, therefore can increase contraposition precision, and can reduce product generation fold.
In addition, upper heater 30 can pass through upper molded plate 31, and the thermal energy conduction that it is produced, to film 51, to increase the efficiency of heating surface of film 51, and can reduce molding time.
More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, in the situation that do not depart from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all will falling into protection scope of the present invention.
