Embodiment Construction

[0017] refer to figure 1 , the present invention proposes a material molding preparation method for a double-threaded in-mold coating, comprising the following steps.

[0018] S1. Shape the first upper mold and the first lower mold. The lower surface of the first upper mold is provided with a fixed film area for fixing the film to be pasted, and the upper surface of the first lower mold is provided with a printing area for printing.

[0019] In this embodiment, the film fixing area of ​​the first upper mold is provided with a plurality of through holes, and each through hole is connected to a preset negative pressure mechanism such as an air suction machine, and the first upper mold positions the film to be pasted by the pressure difference. Specifically, the inside of the first upper mold is provided with a cavity that communicates with each through hole in the film-fixing area, and the negative pressure mechanism makes the film on the film-fixing area stick and position by s...

Abstract

The invention discloses a material forming preparation method for double-threaded in-mold film coating, comprising the following steps: S4, fixing the film to be pasted in the film fixing area, coating ink in the printing area to form characters to be printed, and passing through the first upper die Close the mold with the first lower mold, and adhere the ink layer on the lower surface of the film to be pasted; close the second upper mold and the second lower mold, and inject liquid raw materials into the injection cavity to form a plastic component; S5. The mold is separated from the first lower mold, and the film to be attached to the ink layer stays in the fixed film area; the second upper mold is separated from the second lower mold, and the plastic component stays on the second lower mold; S6, through the first upper mold The mold and the second lower mold are closed, and the film to be pasted is adhered to the plastic component. The invention avoids the transfer work of the film and the plastic component, that is, avoids the damage to the film and the plastic component caused by the frequent transfer of the process, and improves the process efficiency and the quality of the finished product.

Description

technical field [0001] The invention relates to the technical field of in-mold coating, in particular to a material forming preparation method for dual-thread in-mold coating. Background technique [0002] In the existing in-mold lamination process, the ink layer is printed on the film to be pasted, and then the film to be pasted is pasted on the plastic component through the in-mold film. In this process, the film and plastic components to be pasted need to be prepared in advance, and then transferred to the film-coated mold. During the transfer process of the film and plastic components, it is easy to cause damage to the film and plastic components, which increases the cost and is not conducive to improving production efficiency. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a material forming preparation method for in-mold coating with two threads. [0004] A material forming pr...
