Abstract

The utility model provides a labeling is used in shaping in plastic work piece mould, including substrate layer and heat seal layer, substrate layer and heat seal layer form laminated structure, substrate layer surface coating has the printing layer, runs through on its whole thickness direction and has a plurality of through-hole so that printing layer surface and heat seal layer surface switch on, a plurality of through-hole interval sets up. The utility model provides a pair of labeling is used in mould internal forming, its through-hole can make the clamp stay the gas between labeling and the plastic work piece and discharge from one side that the through-hole is located the printing layer fast in the mould internal forming process at the plastic work piece, prevents that gas from being detained and causes the phenomenon of labeling foaming fold between labeling and plastic work piece.

Description

Label for plastic workpiece mould internal forming

Technical Field

The utility model relates to an attached labeling in plastic work piece especially relates to an attached labeling of using of shaping in plastic work piece mould.

Background

In the molding of a resin molding device, a method of molding a resin-molded plastic work piece integrated with a label at one time is called an "in-mold sticking molding method", that is, a label is inserted into a mold for molding a plastic work piece in advance, and the plastic work piece is molded in the mold by an injection molding process, a hollow blow molding process, a two-step blowing process for PET bottle blowing, or the like, so that the label and the molded plastic work piece are integrated in a high-temperature molding process. However, in such a molding process, there is a possibility that the label may be uneven or foamed due to the possibility of air existing between the label and the molded plastic workpiece.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the embodiment of the utility model provides a shaping is labeling in more smooth plastic work piece mould for shaping. The technical scheme is as follows:

the utility model provides a labeling is used in shaping in plastic work piece mould, including substrate layer and heat seal layer, substrate layer and heat seal layer form laminated structure, substrate layer surface coating has the printing layer, runs through on its whole thickness direction and has a plurality of through-hole so that printing layer surface and heat seal layer surface switch on, a plurality of through-hole interval sets up.

Preferably, the through holes are uniformly distributed on the surface of the base.

Preferably, the through hole is formed by laser beam or physical mechanical means.

Preferably, the physical mechanical means is to form a needle on the surface of the roller or form a needle on the surface of the flat plate, and the label is pressed by the needle to complete the punching.

Preferably, the through holes are arranged in a preset pattern or character shape.

The utility model provides a pair of labeling is used in mould internal forming, its through-hole can make the clamp stay the gas between labeling and the plastic work piece and discharge from one side that the through-hole is located the printing layer fast in the mould internal forming process at the plastic work piece, prevents that gas from being detained and causes the phenomenon of labeling foaming fold between labeling and plastic work piece.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Fig. 1 is a schematic structural view of a label for in-mold forming provided in an embodiment of the present invention;

FIG. 2 is a sectional view taken along line A-A of FIG. 1;

fig. 3 is an enlarged view of a portion B of fig. 2.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The utility model provides a labeling is used in shaping in plastic work piece mould, as shown in fig. 1-3, including substrate layer 1 and heat seal layer 2, substrate layer and heat seal layer form laminated structure, substrate layer surface coating has printing layer 3, printing layer 3 can be for printing characters or pattern on substrate layer surface, substrate layer 1 can adopt thermoplastic resin, heat seal layer 2 is solid-like at the normal atmospheric temperature, but when the shaping adherend in the mould, the heat of resin makes the heat seal nature resin layer activate after the melting, makes it bond with the adherend melting, becomes solid-like once more after the cooling, can give play to firm adhesion in order to shape with the utensil. The plastic workpiece can be made into bottles, bottle caps and other appliances through injection molding process, hollow blow molding process or PET bottle blow molding process.

A plurality of through holes 3 penetrate through the whole thickness direction of the printing plate to enable the surface of the printing plate to be communicated with the surface of the heat seal layer, and the through holes are uniformly distributed on the surface of the printing plate. The through hole can be punched by adopting a laser beam or by adopting a physical mechanical means, the physical mechanical means is that a needle is arranged on the surface of the roller or a needle is arranged on the surface of the flat plate, and the label is pressed by the needle to complete the punching purpose.

The through holes are arranged into preset patterns or character shapes, such as information of trademarks of products and the like, so that the effects of attractiveness and counterfeit prevention are achieved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
