Abstract

The invention relates to a mould for forming an in-mould decoration transfer printing device, which comprises a fixed module and a moving module, wherein the fixed module is provided with a forming groove and a plurality of first pouring channels communicated with a main feed end; the moving module is provided with a plurality of demoulding pipelines and second pouring channels which are respectively communicated with one demoulding pipeline in the moving module. When the moving module clamps and fixes a module, plastics at the main feed end are respectively poured into the forming groove through the first pouring channels, the second pouring channels and the demoulding pipelines to disperse the pressure of the plastics.

Description

technical field [0001] The invention relates to a molding die, in particular to a molding die applied to in-mold decoration transfer printing equipment. Background technique [0002] In recent years, In-Mold Decoration (IMD) technology has developed for many years and has gradually become one of the mainstreams of product appearance design. With the increasingly complex changes in product shapes, it has been applied to many forms, such as: In-Mold Forming (IMF) technology, In-Mold Roller (IMR) technology, etc. [0003] Among them, the in-mold transfer printing technology is before the plastic is injected into the mold. The film with printing ink has been placed in the mold in advance, waiting for the combination of printing ink and plastic to improve the visual and diversity of product shell decoration. However, in the application process of in-mold transfer printing technology, the setting conditions of plastic injection into the mold, such as temperature, pressure and spe...
