Description

The double-colored ejection shaping die of in-mold decoration

Technical field

The utility model mainly provides a kind of structure technology about mould, refer to especially a kind of can be utilizing the manufacturing process of dual in-mold decoration IMD (In Mold Decoration), and reach full-automatic purpose of producing three-dimensional double-colored ejaculation product.

Background technology

IMD (In Mold Decoration) technology is the international at present surface decoration technique that is in fashion, utilize surface sclerosis transparent membrane, middle printing pattern layer, back side injection molded layers, printing ink is therebetween, can prevent that product surface is more wear-resisting and in order to avoid scratched, and can keep the distinctness of color to be difficult for fading for a long time.

The double-colored ejaculation product of solid (3D) that present stage is common, carry out the first look ejection formation with IMF (InMold Film) technology among the utilization IMD earlier, and generation product inner liner, then then with the second time ejection formation means produce the skin of product, treat to carry out operations such as application, printing again in superficies after outer the generation, to produce desired pattern and label.

Owing to also will pass through application, printing, therefore can influence production efficiency of products and product yield, and pattern and label after the application printing also scratched easily, and wearability is not good yet, so outward appearance can't obtain third dimension (3D) visual effect high-quality, high request.And if the IMR among the IMD (InMold Roller) technology applied in product subsurface decorate, can be in order to solve relevant exterior design of prior art and label is also scratched easily, wearability is not good problem; Yet, when a product wants gradation to carry out two kinds of different technologies of IMF, IMR, can produce in its process that die cost improves, secondary processing product is to the problem of bit period elongated (production efficiency reduction).

In view of this, the designer improves and researches and develops at double-colored ejection shaping die, and then a kind of double-colored ejection shaping die of in-mold decoration that can carry out automation IMF, IMR ejaculation operation on same board in regular turn is provided.

Summary of the invention

Main purpose of the present utility model is providing a kind of in-mold decoration double-colored ejection shaping die, and it utilizes the manufacturing process of dual in-mold decoration IMD (In Mold Decoration), and reaches full-automatic purpose of producing three-dimensional double-colored ejaculation product.

For reaching above-mentioned purpose, the double-colored ejection shaping die of the utility model in-mold decoration supplies to be arranged on the make-up machine board, and it comprises at least: a male model benevolence, inboard are provided with first an ejaculation groove for the ejaculation of the first chromatograph plastics; One first mother module core, involutory in aforementioned male model benevolence, and for the setting of one first in-mold decoration film, make the first in-mold decoration film close in first and penetrate the groove outside; One second mother module core is transferred contraposition for male model benevolence behind the first chromatograph plastics ejection formation, and covers for one second in-mold decoration film; And a pressure ring, be clamped between the male model benevolence and second mother module core, and be provided with one corresponding to the outside of this first in-mold decoration film, inboard that this second in-mold decoration film covers and second penetrate groove for what the second chromatograph plastics penetrated.

The described first in-mold decoration film is that IMF (In Mold Film) film, the second in-mold decoration film are IMR (In Mold Roller) film, and these second chromatograph plastics are transparent aspect.

Rely on this utilizing the manufacturing process of dual IMD (In Mold Decoration), and reach full-automatic purpose of producing three-dimensional (3D) double-colored ejaculation product; And compared to prior art, the utility model can obtain third dimension (3D) the vision processing effect of higher quality, high request, and the decorative effect that product is presented is more wear-resisting and be difficult for scratching, and makes product carry out IMF, IMR in regular turn adding the die cost in man-hour and reduce, make producing of product more efficient.

The specific embodiment

See also shown in Figure 1, overall structure schematic diagram for the utility model most preferred embodiment, disclose the double-colored ejection shaping die 10 of in-mold decoration among the figure, for being arranged on the make-up machine board 100, it comprises a male model benevolence 11, one first mother module core 12, one second mother module core 13 and a pressure ring 14 at least.

See also Figure 1 and Figure 2, wherein Fig. 2 is the utility model male model benevolence and the corresponding schematic diagram of first mother module core; Male model benevolence 11 inboards are provided with the first ejaculation groove, 111, the first mother module cores 12 that supply the first chromatograph plastics to penetrate, and are involutory in aforementioned male model benevolence 11, and are provided with for one first in-mold decoration film 20, make the first in-mold decoration film, 20 films close in the first ejaculation groove outside; This first in-mold decoration film 20 is IMF (In Mold Film) film, can from the special fixture platform, it be drawn on placement first mother module core 12 by the manipulator on the board 100, and via the located in connection on first mother module core 12, contraposition mechanism (common reference column in for example general mould) with the first in-mold decoration film, 20 location, by the getter devices in first mother module core 12 first mother module core 12 is close in thin 20 absorption of the first in-mold decoration film again.
