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.

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0019] Such as figure 1 and 2 An in-mold film sticking mold with a stable effect is shown, including a fixed mold 1 above and a moving mold below. connected, the mounting plate 3 is provided with a top plate 5, the upper surface of the movable template 2 has a large groove 6 for the decorative film to be placed in, and several grooves for the extended edge of the decorative film are placed around the large groove 6. The small grooves 7 are connected. After the fixed mold 1 and the movable mold are closed, a mold cavity 8 is formed in the middle, and a number of pressure film cavities 9 connected with the mold cavity 8 are formed around the cavity 8. The height of the pressure film cavity 9 is ...

The invention discloses an in-mold film attaching mold with a stable effect. The in-mold film attaching mold comprises a fixed mold body on the upper portion and a movable mold body on the lower portion. The movable mold body comprises a movable mold plate and an installation plate. An ejection plate is arranged on the installation plate. A mold cavity is formed after the fixed mold body and the movable mold body are assembled. A plurality of pressing mold cavities connected with the mold cavity are formed around the mold cavity. The height of each pressing mold cavity is slightly larger than the thickness of a decoration film. Cutter channels are formed in the movable mold plate. Cutters are installed in the cutter channels. The cutter channels are connected with the pressing mold cavities. The cutters are connected with the ejection plate through connecting rods. Replaceable elastic pressing bars are arranged on the lower surface of the fixed mold body. The elastic pressing bars correspond to small grooves in position. According to the in-mold film attaching mold with the stable effect, decoration films with different thicknesses can be firmly fixed and are protected against displacement in the mold assembly and injection molding processes, the film attaching effect is stable, and the procedure is simple and convenient to implement.
Description
technical field [0001] The invention relates to an in-mold film sticking mold with stable effect, belonging to the field of injection molds. Background technique [0002] In-mold decoration technology (IMD) is currently a popular surface decoration technology in the world. The surface is hardened transparent film, the middle printing pattern layer, the back injection molding layer, and the middle of the ink, which can prevent the surface of the product from being scratched and rubbed, and can maintain the color for a long time The bright color is not easy to fade. It is printed on the surface of the film, high-pressure formed, and then put into the injection mold to make it integrally formed with the injection material. However, in the actual injection molding process, after the decorative film is placed in the cavity, the film is often wrinkled and shifted due to the inability of the film to adhere tightly to the cavity, or the impact of the fluid during injection molding,...
