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...

The invention discloses a material forming preparation method for double-threaded in-mold film coating. The material forming preparation method comprises the following steps that S4, a thin film to beattached is fixed in a film-fixing area, a printing area is coated with ink to form a character to be printed, and through the mold assembly of a first upper mold and a first lower mold, an ink layeris adhered to the lower surface of the thin film to be attached; a second upper mold and a second lower mold are assembled, and a liquid raw material is injected into an injection molding cavity to form a plastic part; S5, the first upper mold is separated from the first lower mold, the thin film to be attached and adhered to the ink layer stays in the film-fixing area; the second upper mold is separated from the second lower mold, and the plastic part stays on the second lower mold; and S6, through the mold assembly of the first upper mold and the second lower mold, and the thin film to be attached is adhered to the plastic part. The material forming preparation method avoids the damage to the thin film and the plastic part due to frequent transfer of processes by avoiding the transfer work of the thin film and the plastic part, thereby improving the process efficiency and the quality of finished products.
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...
