Embodiment Construction

[0025] A specific embodiment of a shape-adaptive in-mold decoration method of the present invention will be explained below with reference to the accompanying drawings.

[0026] Firstly, the roll-shaped decorative film is placed on the conveyor substrate, and the feeder clamps the decorative film and conveys it to a set length. This kind of decorative film can generally be divided into three layers: (1) Substrate, generally polyethylene terephthalate, referred to as PET, or polycarbonate, referred to as PC, or polymethyl methacrylate, referred to as PMMA , the requirement for base material selection is that it has good molding and processing properties; (2) the ink layer, which is a printing material, requires wear resistance, high temperature resistance, and good performance in blending and screen printing operations; (3) protective film, or It is a special adhesive or polyethylene (PE). The requirement of the protective film is that it has good surface wear resistance and ch...

Abstract

The invention relates to a shape self-adaptive in-mold decorating method, which comprises the following production steps: 1, conveying a decorating film by a material conveyer; 2, cutting the decorating film; 3, rotating a base plate of a conveyer, and placing the cut decorating film in a vertical position; 4, using a mechanical hand for conveying the decorating film to a position in front of a forming cavity of a mold; 5, using a controllable air flow for regulating the position and the shape of the decorating film; 6, using a material pressing frame for fixing the decorating film; 7, heating the film; 8, carrying out vacuum injection suction forming on the decorating film after the mold assembly, and prefabricating injection molding holes; and 9, controlling an injection molding machine and peripheral equipment to start injection molding, if required after the third step, rotating the cut decorating film for 90 degrees for changing the printing direction of patterns of the decorating film. The decorating film comprises a transfer printing film and an in-mold transfer printing film. The invention has the advantages that the film does not need to be preprocessed and pretreated in advance, products or parts with surface decoration in any shape can be produced only through one work procedure, the production cost is low, and the popularization is easy.

Description

【Technical field】 [0001] The invention relates to the technical field of production and processing of automobiles and home appliance parts, in particular to a shape self-adaptive technology that can produce decorative products or parts with only one process without being limited by the shape, shape angle and forming depth of the parts. Method of in-mold decoration. 【Background technique】 [0002] In-mold decoration technology (English name is In-Mold Decoration, referred to as IMD) is currently a popular product (or part) surface decoration technology in the world. With the rise of light, thin and short consumer electronic products in the market and the enhancement of people's awareness of environmental protection, traditional plastic processing technology can no longer meet the requirements of modern society for new products, and in-mold decoration technology (IMD) came into being . [0003] In-mold decoration technology (IMD) refers to a method of making a printed decora...
