Embodiment approach

[0032] see Figure 5 , the second preferred embodiment of the molding method for in-mold decoration of the present invention includes the following steps:

[0033] Step 202, providing a carrier film; the carrier film is printed with desired patterns such as patterns, patterns and colors on one side or at a certain distance, and the part printed with the desired patterns is made of a transparent film. Obviously, the carrier film can also be entirely made of a transparent film.

[0034] Step 204 , use the film feeding device 10 to pull the carrier film and send the carrier film between the female die 20 and the male die 30 along the intersection line of the male and female dies 30 , 20 .

[0035] Step 206 , aligning the part of the carrier film printed with the required pattern, pattern and color with the mold cavity 22 .

[0036] In step 208 , the carrier film is tightly attached to the inner wall of the mold cavity 22 of the master mold 20 . In this preferred embodiment, th...

Abstract

The invention relates to an in-mold decoration forming method, which comprises the following steps: providing a carrier thin film, wherein patterns to be attached to plastic products are printed on one surface of the carrier thin film; conveying the carrier thin film to in-mold decoration forming equipment; performing mold assembly, and cutting off the patterns to be attached to the plastic products on the carrier thin film from the carrier thin film; performing injection forming to enable the patterns cut off from the carrier thin film to be attached to the surface of a forming piece; and performing mold unloading and removing the part after the carrier thin film is cut off from the in-mold decoration forming equipment. By the in-mold decoration forming method, the thin film to be attached to the plastic products is attached to the carrier thin film which can utilize a film conveying device to convey the film automatically so as to realize continuous automated production.

Description

technical field [0001] The invention relates to an in-mold decoration forming method. Background technique [0002] In-mold insert injection molding (IML, In Mold Label) is a commonly used in-mold decoration molding method. Its process features are: a transparent film printed with a pattern layer is placed in the mold, and after injection molding, the transparent film is pasted. Attached to the surface of the product, the pattern layer is located between the transparent film and the plastic layer. Because the ink is sandwiched in the middle, the product can prevent the surface from being scratched and abrasion-resistant, and can keep the color bright and not easy to fade for a long time. [0003] However, during the injection molding of in-mold inserts, a transparent film needs to be placed into the mold in each molding cycle, which cannot realize continuous automatic production, and the production efficiency is low. Contents of the invention [0004] In view of this, it ...
