Embodiment Construction

[0028] The following is further described in detail through specific implementation methods:

[0029] figure 1 It is a product technology roadmap of the present invention, and the specific steps are as follows:

[0030] 1. Using Moldflow software for mold flow analysis research and structural optimization

[0031] 1 Mold flow analysis using Moldflow software

[0032] First, use UG software to build a 3D model of the curved window product, import the established 3D model of the curved window product into the Moldflow software, select the Fusion format for mesh division, and correct the defects of the mesh.

Abstract

The invention relates to an in-mold injection molding method of a curved window in the technical field of display window product processing. The in-mold injection molding method comprises the following steps of (1), carrying out mold flow analysis research and structure optimization by utilizing Moldflow software; (2) designing a curved window IMR mold; and (3) performing curved window product mold testing, production process optimization and mold testing and analyzing the mounting, adjusting and sample testing processes of a mold and equipment. The curved window IMR process is reliable, molddesign optimization is reasonable, IMR forming of a curved window product is successfully achieved, the production efficiency is high, and beneficial experience is provided for IMR technology and molddesign of large plastic products in the future.

Description

technical field [0001] The invention relates to the technical field of display window product processing, in particular to an in-mold injection molding method for a curved surface window. Background technique [0002] IMD technology is a general term for in-mold insert molding (IML), in-mold insert molding (IMF) and in-mold transfer printing (IMR). Among them, IML technology is suitable for 2D plastic parts with no stretch and small curved surface; IMF technology is suitable for 3D plastic parts with high stretch and large curved surface; IMR technology is to peel off the plastic sheet on the decorative film, leaving only Ink on the surface of the plastic part. Due to the similarity between IML technology and IMF technology, some professionals divide IMD into two types: IML (IMF) and IMR. The biggest difference between these two types of processes lies in the difference in the surface of the plastic part. The surface has only ink layer. [0003] In the second half of 2006...
