Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically to a hot-press injection molding die. Background Technology

[0002] A phone cover is a component that is fitted onto a mobile phone to protect the internal parts of the phone. To meet market demands, phone covers come in a variety of shapes and materials, including glass, plastic, flat, and curved shapes.

[0003] In existing technologies, single-material phone cover plates are generally easier to process, requiring only the use of appropriate molds to process the sheet material. However, for phone cover plates made of multiple materials, a step-by-step molding process is often necessary. For example, curved glass phone cover plates with plastic splicing structures are typically produced by hot-pressing and bending the glass sheet using a hot-pressing bending mold, then transferring the bent sheet to an injection mold for injection molding, so that the plastic structure is spliced ​​onto the bent glass sheet; or by bending the glass sheet, injection molding the plastic structure, and then assembling the separately formed glass sheet and plastic structure into one piece.

[0004] The above molding and processing methods require further transfer or assembly of the sheet materials, which generally consumes a certain amount of turnaround time during production, thus affecting the overall production efficiency of mobile phone cover panels. In particular, mobile phone cover panels that are molded separately from components of different materials and then assembled not only have low production efficiency, but also have low bonding strength after assembly, resulting in poor overall quality and service life of the mobile phone cover panels.
