An in-mold film mold

Abstract

The invention discloses an in-mold film pasting die. The in-mold film pasting die comprises a fixed die at the upper part and a movable die at the lower part, wherein the movable die comprises a movable die plate and a mounting plate which are connected through uprights; a top plate is arranged on the mounting plate; a big groove allowing a decorative film to be placed therein is formed in the upper surface of the movable die plate; the periphery of the big groove is connected with a plurality of small grooves allowing extending edges of the decorative film to be placed therein; the fixed die and the movable die are closed to form a cavity therebetween; a plurality of film pressing cavities connected with the cavity are formed around the cavity; the heights of the film pressing cavities are equal to the thickness of the decorative film; cutter channels are arranged on the movable die plate; cutters are arranged in the cutter channels connected with the film pressing cavities; and the cutters are connected with the top plate through connecting rods. According to the in-mold film pasting die, the decorative film is fixed by the die per se, and therefore, has low probability of displacement; the residual decorative film can be automatically cut off; the film pasting effect is stable; and procedures are simple and convenient.

Description

Technical field [0001] The invention relates to an in-mold film sticking mold, which belongs to the field of injection molds. Background technique [0002] In-mold decoration technology (IMD) is the current internationally popular surface decoration technology. The surface hardened transparent film, the middle printing pattern layer, the back injection layer, and the ink middle can prevent the product from scratching and friction resistance on the surface, and can maintain the color for a long time. The vividness is not easy to fade. It is printed and high-pressure formed on the surface of the film, and then placed in an injection mold to make it integral with the injection material. However, in the actual injection molding process, after the decorative film is placed in the cavity, the film cannot be tightly attached to the cavity or the impact of the fluid during injection molding may cause the film to wrinkle and shift, which affects the effect of the film decoration.

AI Technical Summary

Problems solved by technology

However, in the actual injection molding process, after the decorative film is placed in the cavity, it is often because the film cannot be tightly attached to the cavity, or the impact of the fluid during injection molding causes the film to wrinkle and shift, which affects the effect of film decoration.
