Abstract
The invention discloses a preparing method and mould of hollow container with print material, which comprises the following steps: (1) printing image on the film material, (2) cutting the printed film material mould into the needed shape and size, (3) starting mould, placing the cut film material in the mould cavity, locking the mould, (4) heating the plastic, spraying the plastic in the mould through the sprayer of injection machine, (5) cooling, starting the mould, stripping. The mould possesses inner core and outer core with the height of external core higher than inner core with inner core connecting extending device or inner core possessing gap with external core.
Description
Technical field
The present invention relates to field of plastic products, be specifically related to a kind of manufacture method and mould therefor thereof of the hollow container with printed article.
Background technology
The hollow container of selling on the market mostly is cylindrical at present, conical, traditional is cylindrical, the making of plastic objects such as taper shape, as water tumbler, cylindrical plastic vessel etc., all be that first injection molded is again at the outside printed patterns, because there is certain curvature on its surface, generally can only adopt transfer-print technology or screen printing technique now, and the printing of above-mentioned two kinds of forms also can only be common color lump, the printing of line engraving or coarse net point (50-150 netting twine), can not go up at above-mentioned these objects (product) and realize exquisite printing, some technological high-grade printings of more impossible realization are as stereoeffect, animation effect etc.
Summary of the invention
The objective of the invention is in order to solve the deficiencies in the prior art, a kind of plane offset printing technology that adopts present advanced person is provided, the picture that is beautifully printed earlier, advertisement etc., and then the manufacture method of moulding a kind of hollow container with printed article of manufacturing various plastic products.
Another object of the present invention provides the used mould of a kind of above-mentioned manufacture method.
The present invention is a kind of manufacture method of the hollow container with printed article, and it mainly comprises following operation:
(1) on film condensation material, prints image with offset press;
(2) film condensation material that will print image is die-cut to needed shape and size;
(3) opening mold, the film condensation material that cross cutting is good is put die cavity into, locks mould then;
(4) plastics that are used for injection moulding are heated, plastics are injected die for molding by the injection machine shower nozzle;
(5) after the cooling, opening mold is with product stripping.
Above-mentioned used film condensation material and plastics are polypropylene (PP) resin or polyethylene to acid esters (PET) resin too;
Above-mentioned nozzle temperature remains on 200 ℃～260 ℃;
The used mould of above-mentioned manufacture method, comprise train wheel bridge, frame assembly, core body and lower plate, frame assembly is installed between train wheel bridge and the lower plate, core body is arranged in the frame assembly, it is characterized in that: described core body is provided with inner core and the outer core that is fitted to each other, and the aspect ratio inner core height of outer core, inner core is connected with between retractor device or inner core and the outer core gapped simultaneously;
Above-mentioned retractor device is the hydraulic piston pillar, and its effect is to make mold core and outer core can relatively move in the axial direction.
Compared with prior art, the present invention has following beneficial effect: the present invention adopt the produced hollow container of the method for first planographic aftershaping be beautifully printed, lucuriant in design; Film condensation material and hollow container fuse together by the mode of injection molding, and image is between film condensation material and container, and the retention time that is difficult for fading is long.

The specific embodiment
Below in conjunction with embodiment the present invention is described in further detail.
Embodiment 1
With the four looks little Sen Liselong offset press of Japan printing color image on the raster film made from polypropylene (PP) resin, image can be selected as required; The raster film that will print coloured image then is die-cut to fan-shaped with die-cutting machine, the fan-shaped grating film is put in the mould with the inner core A3 that is fitted to each other and outer core A4, the surface of this mould core body is that circular cone and outer core A4 are highly a little than inner core A3 height again.Fan-shaped raster film surrounds the ring-like conical surface and cooperates with mold shape in mould.Injection machine adopts ZY-180 type hydraulic pressure injection molding machine of plastic, and the injection machine nozzle temperature remains on 200 ℃.Polypropylene (PP) resin is the smallest end notes progressive die tool of mould core body from the top of mould, because the outer core A4 of mould is highly a little than inner core A3 height, so plastics fill up the top of die cavity earlier in mould, inner core A3 because of mould is connected with hydraulic piston pillar A5 again, can relatively move on axis with outer core A4, under the effect of pressure, the external mutually core A4 of the inner core A3 of mould moves, plastics moments is filled up the space between mold core A3 and the outer core A4, and raster film then fuses the outer surface at hollow container.After the cooling, opening mold will will can dispatch from the factory after the packing of product then with the conical hollow container demoulding of printed article.
Through the plastic containers that this method is produced, outside surface image is clear, and is bright in luster and have very strong stereoeffect, has also practical value of artistic value.
Embodiment 2
The injection machine nozzle temperature remains on 220 ℃, and production procedure is identical with embodiment 1.
Embodiment 3
With the little Sen Liselong offset press of four looks Japan printing color image on the raster film of acid esters (PET) resin too being made with polyethylene, image can be selected as required; The raster film that will print coloured image then is die-cut to rectangle with die-cutting machine, again the rectangular raster film is put in the mould with the inner core B3 that is fitted to each other and outer core B4, the B3 core is a cylinder in this mould, the inner surface of outer core B4 is the face of cylinder, and between outer core B4 and the inner core B3 fixed gap being arranged, its thickness is thickness of container wall after the moulding.The rectangular raster film surrounds the inwall that core B4 outside the mould is close on the face of cylinder in mould.Injection machine adopts ZY-500 type hydraulic pressure injection molding machine of plastic, the injection machine nozzle temperature remains on 260 ℃, polyethylene is annotated the progressive die tool from the top of mould acid esters (PET) resin too, because the outer core B4 of mould is highly a little than gapped between inner core B3 height and outer core B4 and the inner core B3, so plastics begin diffusion until filling up die cavity by the top in die cavity, form hollow container, raster film then fuses the outer surface at hollow container.After the cooling, opening mold will will can dispatch from the factory after the packing of product then with the cylindrical hollow container demoulding of printed article.
Through the plastic containers that this method is produced, outside surface image is clear, and is bright in luster and have very strong stereoeffect, has also practical value of artistic value.
Embodiment 4
The injection machine nozzle temperature remains on 240 ℃, and production procedure is identical with embodiment 3.
The manufacture method of the hollow container of band printed article disclosed by the invention should not only limit to the manufacture method of conical hollow container or cylindrical hollow container, how all should include protection scope of the present invention in as long as use its shape of container of this method manufacturing.
